I. CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application No. 62/459,784, filed Feb. 16, 2017, the content of which is hereby incorporated by reference herein in its entirety.

II. FIELD

Provided herein are methods for treating schizophrenia, and various compounds and compositions comprising the compounds, for use therein.

III. BACKGROUND

Central nervous system disorders affect a wide range of the population with differing severity. Generally, the major feature of this class of disorders includes the significant impairment of cognition or memory that represents a marked deterioration from a previous level of functioning.
Schizophrenia is a psychopathic disorder of unknown origin, which usually appears for the first time in early adulthood and is marked by characteristics such as, psychotic symptoms, phasic progression and development, and/or deterioration in social behavior and professional capability. Schizophrenia is also a chronic and disabling disorder with a heterogeneous clinical presentation characterized by symptoms across a range of psychological, behavioral, and cognitive domains. A DSM-5 diagnosis of schizophrenia requires the presence of at least 3 criteria in the domains of positive symptoms (delusions or hallucinations), negative symptoms (diminished emotional expression or avolition), or disorganized thinking/behavior (disorganized speech or grossly disorganized behavior or catatonia). Associated symptoms supporting the diagnosis include symptoms occurring in 2 additional domains of depression/anxiety and hostility/excitement. See, e.g., Diagnostic and Statistical Manual of Mental Disorders, 5^thEd., American Psychiatric Association (2013) (DSM-V™, aka DSM-5).
Since its introduction in 1987, the Positive and Negative Syndrome Scale (PANSS), consisting of 30 items, has been the most widely used measure of schizophrenia illness severity, and the PANSS total score is the gold standard primary efficacy measure in acute treatment studies of schizophrenia. Factor analyses of the PANSS have consistently identified 5 factors, which are frequently used as secondary efficacy measures, and which map on to DSM-5 core, and associated, diagnostic criteria: positive symptoms, negative symptoms, disorganized thinking, hostility/excitement, and symptoms of depression/anxiety.
Positive symptoms are those, which represent an “excess” of normal experiences, such as hallucinations and delusions. Negative symptoms are those where the patient suffers from a lack of normal experiences, such as anhedonia and lack of social interaction. The cognitive symptoms relate to cognitive impairment in schizophrenics, such as lack of sustained attention and deficits in decision making. The current antipsychotics may be successful in treating the positive symptoms but fare less well for the negative and cognitive symptoms.
A significant impediment to establishing the efficacy of new drugs for the treatment of specific symptom domains (e.g., negative symptoms or cognitive dysfunction) is the extent to which PANSS factors are correlated with each other. As a consequence, it has not been possible to determine whether improvement in the severity of symptoms in the five PANSS factors is a domain-specific treatment effect, or is a non-specific effect secondary to observed improvement in correlated PANSS items.
Accordingly, although both first and second generation antipsychotic medications have demonstrated significant efficacy in the treatment of positive symptoms of schizophrenia, hostility/excitement, and (to a lesser degree) symptoms of depression/anxiety. However, comparably effective treatment of negative symptoms and cognitive dysfunction remains an unmet need.
Therefore, there is a great need for effective treatments for the negative symptoms and cognitive dysfunction symptoms of schizophrenia.

V. BRIEF DESCRIPTION OF THE DRAWINGS

In the accompanying drawings like reference numerals indicate like elements and features in the various figures. For clarity, not every element may be labeled in every figure. In addition, the drawings are not necessarily complete when viewed without reference to the text, emphasis instead being placed upon illustrating the principles of the inventions.

FIG. 1 presents a correlation matrix heat map of PANSS item scores for all patients at baseline (N=1710). The dendrogram (far right) displays clustering of related items according to a distance metric (1-r²), where closely related items were more correlated than distantly related items (x-axis). The branches are labeled according to the clustering of items. Each row corresponds to an item in PANSS (labeled on far left) with identity to each column in the correlation matrix along the diagonal. The columns under heading MARDER FACTORS collect correlations between each item rating and each of 5 Marder PANSS factor scores vs rows. Items identified by the Marder model are labeled with letters as follows: P for positive, D for disorganized, A for anxiety/depression, H for hostility, and N for negative. The CORRELATION MATRIX is shaded according to Pearson's r value between each item (higher absolute values of r having a darker shading) and is symmetrical across the diagonal. Boxed areas identify clusters of items with higher correlations (darker shading) and correspond to the clustering in the dendrogram branches.

FIG. 2 presents a correlation matrix heat map of PANSS item scores for all observations' change from baseline. Correlations of individual item change scores (rows) are shown relative to the transformed PANSS factor change scores (columns under heading TRANSFORMED FACTORS), or relative to the Marder PANSS factors. Transformed PANSS factors were calculated using the coefficients of the score matrix (see FIG. 4 and Table 4A). The relatively low correlations among items outside of their respective (transformed) factor illustrates specific associations of items with distinct transformed PANSS factors, relative to Marder PANSS factor scores which have substantial correlations outside of their respective PANSS factors. The amount of variance explained by each PANSS factor was identified and labeled for each transformed PANSS factor. The CORRELATION MATRIX is shaded according to Pearson's r value between each item, and corresponds by row to the dendrogram at the far right. Branches in the dendrogram are labeled according to clustering of items, and correspond to boxes along the diagonal of the correlation matrix.

FIG. 3A shows a Forest plot of the effect size change from baseline for placebo. Profile of improvements (change from baseline) in schizophrenia symptoms estimated using PANSS factors. In the left panel of FIG. 3A, shown are within-treatment effect sizes (with 95% CI) for placebo for change from baseline at week 6 endpoint, based on the Marder PANSS factors. In the right panel of FIG. 3A, the same within-treatment effect sizes at endpoint are shown based on the transformed PANSS factors. Transformed PANSS factors were calculated using the coefficients of the score matrix (see FIG. 4 and Table 4A).

FIG. 3B shows a Forest plot of the effect size change from baseline for treatment with lurasidone. Profile of active drug effects on schizophrenia symptom domains. In the left panel of FIG. 3B, shown are lurasidone vs placebo effect sizes (with 95% CI) for change from baseline at week 6 endpoint, based on the Marder PANSS factors. In the right panel of FIG. 3B, the same lurasidone vs placebo effect sizes at endpoint are shown based on the transformed PANSS factors. Drug effects were constructed using a pool of all lurasidone doses (40, 80, 120, or 160 mg/day, total N=993) and excluded active comparators (olanzapine, quetiapine-XR). To examine placebo effects on PANSS factors, placebo treated patients (N=484) were pooled across all studies. Transformed PANSS factors were calculated using the coefficients of the score matrix (see FIG. 4 and Table 4A).

FIG. 4 presents the transformation matrix, also referred to herein as the score matrix and Uncorrelated PANSS Score Matrix (UPSM), that was used to transform Marder PANSS factor data to transformed PANSS factor data. The score matrix itself comprises the matrix from Columns 7 to 13 (inclusive) and rows 2 to 30 (inclusive), and is also presented in Table 4A. Column 1 provides the PANSS factor transformed (e.g. provide the order of the PANSS column vector) and column 14 the name for this PANSS factor. Columns 2 to 6 illustrate the correspondence between the PANSS factors and the associated Marder PANSS factors (here also diagnostic symptom domains), and the traditional weighting of PANSS factors as either “0” or “1.” In FIG. 4, the following abbreviations are used: “POS” means positive symptoms; “DIS” means disorganized thoughts; “NAA” means negative symptoms of apathy/avolition; “NDE” means negative symptom of deficit of expression; “HOS” means hostility; “NEG” means, negative symptoms; “ANX” means anxiety; and “DEP” means depression; “DEP/ANX” means depression/anxiety.

FIG. 5 presents the correlation coefficients among the transformed PANSS factor scores for the validation data of Example 1. Column of the table of FIG. 5 indicates if the study used was from the analysis or validation data set; column 2 the study; column 3 the study design; column 4 the number of subjects; column 5 the study duration; column 6 the transformed PANSS factors (Nfactor) total versus the PANSS factor total; columns 7-10 the Pearson's correlation coefficients between the transformed PANSS factor scores for Positive symptoms (POS) and the other transformed PANSS factor scores (e.g. DIS, AA, DE and HOS); and columns 11-13 the transformed PANSS factor subtotals versus the transformed PANSS factor scores for Positive symptoms. Correlations are presented for change scores to study endpoint for the indicated duration of column 5. The following abbreviations are used: “RCT” means Randomized placebo-Controlled Trial in acute schizophrenia; “RWS” means Randomized Withdrawal Study at endpoint of Open Label (“OL”) or Double Blind (“DB”) period; “POS” means positive symptoms; “DIS” or “Dis” means disorganized thoughts; “AA” also “NAA” means negative symptoms of apathy/avolition; “DE” also “NDE” means negative symptom of deficit of expression; “HOS” or “Hos” means hostility; and “NEG” or “Neg” means, negative symptoms.

VI. DETAILED DESCRIPTION

A. Definitions

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as those commonly understood by one of ordinary skill in the art. In certain embodiments, abbreviations are as defined in J. Org. Chem. 2007, 72, 23A. All publications and patents referred to herein are incorporated by reference herein in their entireties. As used in the specification and the accompanying claims, the indefinite articles “a” and “an” and the definite article “the” include plural as well as singular referents, unless the context clearly dictates otherwise.
As used herein, and unless otherwise specified, the terms “drug” and “therapeutic agent” refer to a compound, or a pharmaceutical composition thereof, which is administered to a subject for treating, preventing, managing, or ameliorating one or more symptoms of a condition, disorder, or disease.
As used herein, and unless otherwise specified, the terms “active ingredient” and “active substance” refer to a compound, which is administered, alone or in combination with one or more pharmaceutically acceptable excipients, to a subject for treating, preventing, or ameliorating one or more symptoms of a condition, disorder, or disease. As used herein, “active ingredient” and “active substance” may be an optically active isomer of a compound described herein.
As used herein, the term “subject,” to which administration is contemplated includes, but is not limited to, humans (i.e., a male or female of any age group, e.g., a pediatric subject (e.g., infant, child, adolescent) or adult subject (e.g., young adult, middle-aged adult or senior adult)) and/or other primates (e.g., cynomolgus monkeys, rhesus monkeys); mammals, including commercially relevant mammals such as cattle, pigs, horses, sheep, goats, cats, and/or dogs; and/or birds, including commercially relevant birds such as chickens, ducks, geese, quail, and/or turkeys.
As used herein, the terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, including but not limited to therapeutic benefit. In various embodiments, treatment may be administered after one or more symptoms have developed. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a subject prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence.
Therapeutic benefit includes eradication and/or amelioration of the underlying disorder being treated; it also includes the eradication and/or amelioration of one or more of the symptoms associated with the underlying disorder such that an improvement is observed in the subject, notwithstanding that the subject may still be afflicted with the underlying disorder. In various embodiments, “treatment” or “treating” includes one or more of the following: (a) inhibiting the disorder (for example, decreasing one or more symptoms resulting from the disorder, and/or diminishing the extent of the disorder); (b) slowing or arresting the development of one or more symptoms associated with the disorder (for example, stabilizing the disorder and/or delaying the worsening or progression of the disorder); and/or (c) relieving the disorder (for example, causing the regression of clinical symptoms, ameliorating the disorder, delaying the progression of the disorder, and/or increasing quality of life.)
As used herein, the term “therapeutically effective amount” or “effective amount” refers to an amount that is effective to elicit the desired biological or medical response, including the amount of a compound that, when administered to a subject for treating a disorder, is sufficient to effect such treatment of the disorder. The effective amount will vary depending on the compound, the disorder, and its severity, and the age, weight, etc. of the subject to be treated. The effective amount may be in one or more doses (for example, a single dose or multiple doses may be required to achieve the desired treatment endpoint). An effective amount may be considered to be given in an effective amount if, in conjunction with one or more other agents, a desirable or beneficial result may be or is achieved. Suitable doses of any co-administered compounds may optionally be lowered due to the combined action, additive or synergistic, of the compound.
As used herein, an “at risk” individual is an individual who is at risk of developing a disorder to be treated. This may be shown, for example, by one or more risk factors, which are measurable parameters that correlate with development of a disorder and are known in the art.
As used herein, “prevention” or “preventing” refers to a regimen that protects against the onset of the disorder such that the clinical symptoms of the disorder do not develop. Accordingly, “prevention” relates to administration of a therapy, including administration of a compound disclosed herein, to a subject before signs of the diseases are detectable in the subject (for example, administration of a compound disclosed herein to a subject in the absence of a detectable syndrome of the disorder). The subject may be an individual at risk of developing the disorder. The terms encompass the inhibition or reduction of a symptom of the particular disease. Patients with familial history of a disease in particular are candidates for preventive regimens in certain embodiments. In addition, patients who have a history of recurring symptoms are also potential candidates for the prevention. In this regard, the term “prevention” may be interchangeably used with the term “prophylactic treatment.”
As used herein, and unless otherwise specified, a “prophylactically effective amount” of a compound is an amount sufficient to prevent a disease or disorder, or prevent its recurrence. A prophylactically effective amount of a compound means an amount of therapeutic agent, alone or in combination with other agents, which provides a prophylactic benefit in the prevention of the disease. The term “prophylactically effective amount” can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent.
As used herein, and unless otherwise specified, the terms “manage,” “managing,” and “management” refer to preventing or slowing the progression, spread or worsening of a disease or disorder, or of one or more symptoms associated with the disease or disorder. In one embodiment, such symptoms are those known to a person of skill in the art to be associated with the disease or disorder being managed. Often, the beneficial effects that a subject derives from a prophylactic and/or therapeutic agent do not result in a cure of the disease or disorder. In this regard, the term “managing” encompasses treating a patient who had suffered from the particular disease in an attempt to prevent or minimize the recurrence of the disease.
As used herein, and unless otherwise specified, the various PANSS factors terms: (P01) delusions, (P02) conceptual disorganization, (P03) hallucinations, (P04) excitement, (P05) grandiosity, (P06) suspiciousness/persecution, and (P07) hostility, (N01) blunted affect, (N02) emotional withdrawal, (N03) poor rapport, (N04) passive/apathetic social withdrawal, (N05) difficulty in abstract thinking, (N06) lack of spontaneity and flow of conversation, and (N07) stereotyped thinking, (G01) somatic concern, (G02) anxiety, (G03) guilt feelings, (G04) tension, (G05) mannerisms and posturing, (G06) depression, (G07) motor retardation, (G08) uncooperativeness, (G09) unusual thought content, (G10) disorientation, (G11) poor attention, (G12) lack of judgment and insight, (G13) disturbance of volition, (G14) poor impulse control, (G15) preoccupation, and (G16) active social avoidance; are used herein in a manner consistent with their accepted meanings in the art. See, e.g., Marder S R, Davis J M, Chouinard G., J. Clin. Psychiatry. 1997; 58:538-546). It is to be understood that the notations in parenthesis, for example (P01), (N05), (G12), etc., are used for ease of reference and convenience.

B. Methods

For decades, the PANSS has been the most widely used measure for evaluating efficacy in randomized clinical trials of acute schizophrenia. However, attribution of specific treatment-related improvements among the various symptom domains within PANSS is limited by the high degree of correlation between PANSS factors. As a consequence, apparent improvement in key clinical domains (e.g., negative symptoms, disorganized thinking/behavior) may largely be attributable to scoring of a correlated clinical domain, such as positive symptoms, a problem frequently referred to as pseudospecificity.
Previous attempts at targeting specific symptom domains, sub-domains or patient sub-populations (e.g. patients with symptoms prominently in a specific symptom sub-domain or sub-domains) have not resulted in regulatory approval, in large measure because multidimensional scales such as the PANSS have not overcome the hurdle of pseudospecificity, i.e., the strong correlation between traditional PANSS factors.
The present inventors have discovered methods which can be used to minimize the correlation or decorrelate the PANSS factors and thus ascertain the potential efficacy of a compound and/or treatment for a specific symptom of schizophrenia, and in various particular embodiments, the potential efficacy of a compound and/or treatment for a negative symptom of schizophrenia.
In various embodiments, methods of the present inventions provide a solution to the problem of pseudospecificity, by validating orthogonal, minimally correlated measures of key clinical domains.
Traditional PANSS factors can be significantly correlated, as a consequence, it has not been possible to determine whether improvement in the severity of symptoms in the five PANSS factors is a domain-specific treatment effect, or is a non-specific effect secondary to observed improvement in correlated PANSS items. The inventors have conducted an analysis of PANSS data from a 6-week treatment study of lurasidone that illustrates such correlation.
The analysis sample consisted of PANSS data derived from 5 similarly-designed, randomized, double-blind, placebo-controlled, 6-week treatment studies of lurasidone or active comparator for the treatment of patients with an acute exacerbation of schizophrenia. Patients (N=1,710) were included in this analysis if they had received at least one dose of study drug, and had at least one post-baseline PANSS assessment. The analysis pooled all lurasidone doses (40, 80, 120, or 160 mg/d, total N=993), and excluded active comparators (olanzapine, quetiapine-XR). To examine placebo effects on PANSS factors, placebo treated patients (N=484) were pooled across all studies. Herein also referred to as the “PANSS Analysis Study.”
To visualize the relatedness among PANSS items, dendrograms were calculated using correlations between items at baseline, and separately using correlations between items in change post baseline. Items with more correlation were considered more closely related and were shown with shorter pairwise branch distances in a dendrogram. Dendrograms were calculated based on the unweighted average distance method in MATLAB R2016a2, and using a distance metric of 1−r², where r is the Pearson correlation between two items.
FIG. 1 presents the correlation matrix heat map of PANSS item scores calculated for all patients at baseline. Schizophrenia symptoms, present at baseline in the pooled sample (N=1,710), were clustered according to the relative correlations among the 30 PANSS items. The baseline correlation matrix identified substantial correlations among PANSS items. To identify clustering of related items, a dendrogram of baseline symptoms was plotted using the correlation matrix as a distance metric. The dendrogram of FIG. 1 (far right), displays clustering of related items according to the distance metric 1−r², where closely related items are more correlated than distantly related items (x-axis). Clusters of items visible as 5 major branches in the dendrogram were identified as 5 domains of psychopathology. The branches are labeled according to the clustering of items.
Ratings on items identified by the original PANSS factor model of Marder (Marder S R, Davis J M, Chouinard G., J. Clin. Psychiatry. 1997; 58:538-546) were summed (with equal weighting) to show correlations between individual PANSS items and the 5 Marder PANSS factors (see FIG. 1). A correspondence was found between the Marder PANSS factors, and branches in the dendrogram.
The change-from-baseline was then examined in the 30 PANSS items. The correlation matrix identified substantial correlations among individual PANSS item change scores. Referring to FIG. 2, a second dendrogram of the PANSS item change scores was plotted to identify clustering of related items using the correlation matrix of change scores as a distance metric, shown in FIG. 2. The dendrogram of FIG. 2 suggested that change-from-baseline in PANSS items exhibited a clustering that was similar to that observed for PANSS items at baseline. In the branch of negative symptoms, for example, the same two distinct subfactors (apathy/avolition and deficit of expression) were evident in both change-from-baseline, and at baseline. Table 1 shows the Pearson's correlation coefficients between the Marder PANSS factors, where the following abbreviations are used: POS, positive symptoms; DIS, disorganized thoughts; Neg, negative symptoms; Hos/Exc, hostility/excitement; Anx/Dep, anxiety/depression; Tot, total.

The analysis of baseline-to-endpoint change in the current pooled data set revealed substantial correlations among the Marder PANSS factors as can be seen in Table 1. For example, endpoint (week 6) change in the Marder PANSS positive factor score was highly correlated with endpoint change in the Marder PANSS negative (r=0.57), PANSS disorganized (r=0.74), PANSS hostile (r=0.64), and PANSS depressed (r=0.52) factor scores.
The present inventors have discovered methods which can be used to minimize the correlation or decorrelate PANSS factors. Despite the availability of dozens of agents across two generations of antipsychotic drugs, there is broad consensus that there remains an unmet need for effective treatments of key clinical dimensions of schizophrenia, most notably negative symptoms and cognitive dysfunction. In various aspects and embodiments, the present inventions provide orthogonal, minimally correlated measures of severity across key symptom domains and/or patient sub-populations, which, for example, could be used by clinicians to more clearly delineate the efficacy of drugs in treating symptom domain, symptom sub-domains and/or patient sub-populations (e.g. patients with symptoms prominently in a specific symptom sub-domain or sub-domains).
In various embodiments, the methods provide transformed PANSS factor score estimates by differentially weighting each PANSS item to optimize its contribution to the relevant factor, while minimizing the contribution of the item to other PANSS factors.
In various embodiments, a score matrix (also referred to herein as an Uncorrelated PANSS Score Matrix, abbreviated UPSM) is used to transform PANSS factor data into transformed PANSS factor data, where the transformed PANSS factors have reduced or minimal correlation between them.
In various embodiments, the methods transform a PANSS data set comprising 30 PANSS factors (see. e.g., Table 4A, column 8, and Table 4B) to produce a data set described by 7 transformed PANSS factors. For example, in various embodiments, the PANSS factors are as listed in Table 4B and the score matrix portion of Table 4A is used to transform the PANSS data substantially as follows:
[PANSS Data]_(N×30)*[UPSM]_(30×7)=[Transformed PANSS Factor Data]_(N×7)
where [PANSS Data]_(N×30)is a matrix with N PANSS assessments and 30 columns for 30 PANSS factors to be transformed; [UPSM]_(30×7)is a matrix with 30 rows (one for each PANSS item) and 7 columns (one for each of the 7 Transformed PANSS Factors); and [Transformed PANSS Factor Data]_(N×7)is the transformed matrix with N PANSS assessments in the 7 columns for 7 Transformed PANSS factors. That is, the coefficients of the uncorrelated PANSS score matrix (the UPSM is a matrix of 30 rows, one of r each PANSS item, ×7 columns, one for each transformed PANSS Factor) are used to transform individual PANSS assessments (ratings expressed either as change from baseline, or as absolute ratings) to reduce 30 items into 7 factor scores (transformed PANSS factor scores) for each PANSS assessment. Each column of the UPSM contains coefficients to multiply the corresponding item scores of PANSS.
In various embodiments, a score matrix for any set of PANSS factors is determined by a maximum likelihood factor analysis upon a matrix of untransformed factors followed by an orthogonal rotation, e.g. a varimax rotation, to produce the score matrix. Communalities greater than 1 in the maximum likelihood factor analysis are compensated for using Heywood criteria (that is, communalities greater than 1 are set to 1, thus no communality is allowed to exceed 1) without a limit on the number of factors produced.
It is to be understood that maximum likelihood factor analysis can have issues with commonalities (which can arise from the interactive way in which communalities are estimated), in addition, maximum likelihood factor analysis is far more computationally intensive than principal factor analysis by two or more orders of magnitude. Further, it is to be understood that rotating a set of factors does not change the statistical explanatory power of the factors. Therefore, there is no a prior choice for orthogonal rotation and choice of rotation cannot be based on statistical grounds. However, the inventors have unexpectedly discovered that a UPSM generated by maximum likelihood factor analysis with a varimax rotation, despite issues communalities has general applicability as further discussed in the Examples.
For example, the UPSM of Table 4A was generated from PANSS data derived from the 5 similarly-designed, randomized, double-blind, placebo-controlled, 6-week treatment studies of lurasidone or active comparator for the treatment of patients with an acute exacerbation of schizophrenia described above (the PANSS Analysis Study) and discussed in the context of Table 1 and FIG. 1 and FIG. 2.
The Uncorrelated PANSS Score Matrix (UPSM) of FIG. 4 and Table 4A was derived using PROC FACTOR procedure of SAS 9.4 with maximum likelihood method (maximum likelihood factor analysis), rotated using the varimax algorithm and compensated for communality greater than 1 using Heywood criteria without a limit on the number of factors produced. A last observation carried forward (LOCF) data imputation method was applied for missing post-baseline PANSS assessments.
An analysis of PANSS assessments as pooled over all post-baseline observations was conducted on the PANSS Analysis Study data. The factoring of change scores was weighted both by repeated measures within-patients as well as by the between-patient measures, and was utilized to increase statistical confidence in the output of the factor analysis. The change-from-baseline transformation of PANSS items (the score matrix) was intentionally derived from an analysis of PANSS over time (study visits) across the study population such that items changing together (vs changing separately) were captured in the structure and coefficients of the score matrix. Remarkably it was discovered that a fixed score matrix applied to disparate patient samples, different trial designs and durations, still retained the properties of orthogonality and high total variance explained with respect to the known factor structure of PANSS.
The ratings of 30 items in the PANSS data of the PANSS Analysis Study were transformed to transformed PANSS factor scores using a score matrix identified by the maximum likelihood method factor analysis conducted on all change from baseline PANSS data from the 5 short-term clinical trials in the pooled analysis sample. The score matrix, also referred to here as the UPSM, consisted of coefficients multiplying the numerical ratings of each PANSS item differentially for each of the factor scores.
The change-from-baseline PANSS data for all patients and all observations N was a matrix of dimensions (N observations×30 items). To increase precision, the score matrix coefficients were determined using all change-from-baseline observations at Weeks 1-6. The resultant score matrix (30 items×7 factors), or UPSM, was used to transform individual PANSS item change scores (without standardization) to reduce the dimensionality into 7-factor values for each PANSS assessment. FIG. 4 and Table 4A summarize the score matrix (UPSM) weights for individual PANSS items used to generate the transformed PANSS factors.
The weighted score matrix transformation was performed on each of the PANSS item baseline-to-endpoint change scores. This transformation yielded 5 transformed PANSS factors that corresponded to the Marder PANSS factors, with two of the factors (negative symptoms and depression/anxiety) further subdivided into sub-factors (corresponding to the symptom sub-domains of: apathy/avolition and deficit of expression; and depression and anxiety, respectively).
Each transformed PANSS factor corresponded preferentially with each of the Marder PANSS factors, as illustrated in Table 2. The transformed PANSS positive symptom factor (POS) correlated well with the Marder positive symptom factor (r=0.79) (see Table 2). The transformed PANSS factor for negative, disorganized, and hostile symptoms were each preferentially correlated with their respective Marder PANSS factors. The transformed PANSS anxiety and depression sub-factors (representing symptom sub-domains) were each well-correlated with the combined Marder PANSS depression/anxiety factor (r=0.74 and r=0.76, respectively).
The amount of variance explained by each transformed PANSS factor is noted in FIG. 2 with 8 to 19% variance explained by each of the 7 transformed PANSS factor scores. PANSS total scores were well-described by sums of the 7 transformed PANSS factor scores, with estimates from regression analysis yielding r²value goodness of fit for p<0.0001 at 0.93.
The transformed PANSS factors resulted in a marked reduction in correlations between the different factors when compared to the substantial correlations observed between the Marder PANSS factors, see for example Table 1. The off-diagonal item correlations evident in the Marder PANSS factors (see Table 1) were substantially reduced in the transformed PANSS factor correlations (see Table 3). In Table 3 the orthogonality of the transformed PANSS factors is evidenced by the lower correlations between the transformed PANSS factors when compared with the higher off-diagonal correlations of the Marder PANSS factors shown in Table 1.
In various aspects, the present inventions utilize existing PANSS data and transform that data with score matrix weighting coefficients to generate transformed PANSS factors with minimal between-factor correlation (enhanced orthogonality) while preserving the correspondence to Marder PANSS factors.
The low between-factor correlations between transformed PANSS factors (see Table 3) indicates that the transformed PANSS factors are measuring independent symptom domains and/or sub-domains, thereby reducing or eliminating pseudospecificity concerns. In addition, the strong correspondence between the transformed PANSS factors and the Marder PANSS factors confirms that each factor is measuring similar, established symptom domains of schizophrenia without substantial loss of statistical validity. These results were further validated as discussed in Examples 1-3, and it has been unexpectedly discovered that various embodiments of these methods provide a robust and generalizable means to address the challenge of pseudospecificity that has, to date, been a limitation in the usefulness of PANSS factors as efficacy measures.
Accordingly, in various aspects provided are methods for determining if a drug has potential efficacy for the treatment for a specific symptom of schizophrenia, and in various particular embodiments, the potential efficacy of a compound for treatment of a negative symptom of schizophrenia.

In various embodiments, subjects can be classified using the UPSM (score matrix) (see FIG. 4 and Table 4A) on the PANSS factors assessed at baseline (“BL”) to produce transformed PANSS factors from which subject classification can be made. In various embodiments, subject PANSS scores are transformed using a score matrix (see FIG. 4 and Table 4A) and clustering the subjects by k-means to identify distinct clusters, each characterized by distinctly prominent baseline transformed PANSS factor scores. A SVM (Support Vector Machine) classifier is then trained on these cluster assignments at baseline, and subsequently used to identify subject sub-population types post-baseline and in external data sets.
For example, in various embodiments, a liner support vector machine classifier is determined substantially as follow, where the score matrix (e.g. UPSM) transforms PANSS data into seven factors. For each cluster in the trainer data (transformed PANSS factors), calculate all possible distance between each Cartesian coordinate point within the cluster and outside the cluster, where the number of Cartesian coordinate points is equal to the number of transformed factors. In this example embodiment, the PANSS factor data is transformed into seven transformed PANSS factors so the coordinate points a 7D (seven dimensional).
Distance between two 7D Cartesian coordinate points (a_i, b_i, c_i, d_i, e_i, f_i, g_i) and (a_j, b_j, c_j, d_j, e_j, f_j, g_j) can be calculated using,
$d_{k} = \sqrt{\begin{matrix} {(a_{i} - a_{j})}^{2} + {(b_{i} - b_{j})}^{2} + {(c_{i} - c_{j})}^{2} + {(d_{i} - d_{j})}^{2} + \\ {(e_{i} - e_{j})}^{2} + {(f_{i} - f_{j})}^{2} + {(g_{i} - g_{j})}^{2} \end{matrix}}$
The process continues with the selection of two of the coordinate points, for example purposes called A and B, that give the give a minimum distance, min (d_k), where point A is within the cluster and point B is outside the cluster.
A hyperplane (of one less dimension than the coordinate dimension, here a 6D hyperplane) is determined where all the points on the hyperplane are equidistant from A and B. That is, if P is on the hyperplane,
$\langle AP \rangle = \langle BP \rangle$ $\sqrt{\begin{matrix} {(a_{i} - a_{k})}^{2} + {(b_{i} - b_{k})}^{2} + {(c_{i} - c_{k})}^{2} + {(d_{i} - d_{k})}^{2} + \\ {(e_{i} - e_{k})}^{2} + {(f_{i} - f_{k})}^{2} + {(g_{i} - g_{k})}^{2} \end{matrix}} = \sqrt{\begin{matrix} {(a_{j} - a_{k})}^{2} + {(b_{j} - b_{k})}^{2} + {(c_{j} - c_{k})}^{2} + {(d_{j} - d_{k})}^{2} + \\ {(e_{j} - e_{k})}^{2} + {(f_{j} - f_{k})}^{2} + {(g_{j} - g_{k})}^{2} \end{matrix}}$
Where the above equation can be used to provide the hyperplane, and where |AP| is the distance between A and P; |BP| is the distance between B and P; A is (a_i, b_i, c_i, d_i, e_i, f_i, g_i); B is (a_j, b, c_j, d_j, e_j, f_j, g_j); and P is (a_k, b_k, c_k, d_k, e_k, f_k, g_k).
The 7 axis of the 7D Cartesian coordinate system (or N axis for an N dimensional coordinate system, e.g., a 5 axis for a 5D coordinate system) along with the 7 hyperplanes (or N hyperplanes for an N dimensional coordinate system) that separate each cluster give the margins (boundaries) of each cluster. Based on the maximum value along each axis, new axis constants (lines x=k or y=t) can be defined to complete polygon margins. These cluster margins complete the training, or cluster margin, and thus classifier determination, for, in this example, Linear SVM. Accordingly, any new Cartesian coordinate (here 7D), i.e. transformed PANSS factor vector, that is the seven transformed PANSS factors of a given subject, can be classified into the clusters based on the cluster margins so defined.
In various embodiments, a comparison of transformed PANSS symptom domain score is used to determine which symptom domain is prominent. In various embodiments, the symptom domain with the highest domain score is determined to be prominent.

In one embodiment, provided herein is a method of treating, preventing, and/or managing a neurological disorder, including schizophrenia, schizophrenia spectrum disorder, acute schizophrenia, chronic schizophrenia, NOS schizophrenia, schizoid personality disorder, schizotypal personality disorder, delusional disorder, psychosis, psychotic disorder, brief psychotic disorder, shared psychotic disorder, psychotic disorder due to a general medical condition, drug-induced psychosis (e.g., cocaine, alcohol, amphetamine), psychoaffective disorder, aggression, delirium, Parkinson's psychosis, excitative psychosis, Tourette's syndrome, organic or NOS psychosis, seizure, agitation, post-traumatic stress disorder, behavior disorder, neurodegenerative disease, Alzheimer's disease, Parkinson's disease, dyskinesias, Huntington's disease, dementia, mood disorder, anxiety, affective disorders (e.g., depression, e.g., major depressive disorder and dysthymia; bipolar disorder, e.g., biopolar depressive disorder; manic disorder; seasonal affective disorder; and attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD)), obsessive-compulsive disorder, vertigo, epilepsy, pain (e.g., neuropathic pain, sensitization accompanying neuropathic pain, and inflammatory pain), fibromyalgia, migraine, cognitive impairment, movement disorder, restless leg syndrome (RLS), multiple sclerosis, sleep disorder, sleep apnea, narcolepsy, excessive daytime sleepiness, jet lag, drowsy side effect of medications, insomnia, substance abuse or dependency (e.g., nicotine, cocaine), addiction, eating disorder, sexual dysfunction, hypertension, emesis, Lesche-Nyhane disease, Wilson's disease, autism, Huntington's chorea, and premenstrual dysphoria, comprising administering to a subject an effective amount of a compound provided herein, or a pharmaceutically acceptable salt or stereoisomer thereof.
In one embodiment, provided herein is a method of treating, preventing, and/or managing a disorder related to psychosis, schizophrenia, ADHD, mood disorder or affective disorder such as depression and anxiety, comprising administering to a subject an effective amount of a compound provided herein. For example, without being limited by a particular theory, the compounds provided herein may improve the gating deficits of DBA/2 mice seen in the pre-pulse inhibition (PPI) test and reverse the methamphe-tamine-induced hyperlocomotor activity. Without being limited to a particular theory, the compounds provided herein may: 1) reverse the amphetamine-induced hyper-locomotor activity; 2) be useful as antipsychotic agents and dosed sparing; 3) improve attention and modulate impulsivity; 4) improve learning parameters in ADHD; 5) enhance learning ability and reduce anxiety in behavioral tests; and/or 6) have an anti-depressant effect.
Any suitable route of administration can be employed for providing the patient with a therapeutically or prophylactically effective dose of an active ingredient. For example, oral, mucosal (e.g., nasal, sublingual, buccal, rectal, vaginal), parenteral (e.g., intravenous, intramuscular), transdermal, and subcutaneous routes can be employed. Exemplary routes of administration include oral, transdermal, and mucosal. Suitable dosage forms for such routes include, but are not limited to, transdermal patches, ophthalmic solutions, sprays, and aerosols. Transdermal compositions can also take the form of creams, lotions, and/or emulsions, which can be included in an appropriate adhesive for application to the skin or can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose. An exemplary transdermal dosage form is a “reservoir type” or “matrix type” patch, which is applied to the skin and worn for a specific period of time to permit the penetration of a desired amount of active ingredient. The patch can be replaced with a fresh patch when necessary to provide constant administration of the active ingredient to the patient.
The amount to be administered to a patient to treat, prevent, and/or manage the disorders described herein will depend upon a variety of factors including the activity of the particular compound employed, or the ester, salt or amide thereof, the route of administration, the time of administration, the rate of excretion or metabolism of the particular compound being employed, the duration of the treatment, other drugs, compounds and/or materials used in combination with the particular compound employed, the age, sex, weight, condition, general health and prior medical history of the patient being treated, and like factors well known in the medical arts.
A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the effective amount required. For example, the physician or veterinarian could start doses of the compounds employed at levels lower than that required in order to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved.
In general, a suitable daily dose of a compound provided herein will be that amount of the compound which is the lowest dose effective to produce a therapeutic or prophylactic effect. Such an effective dose will generally depend upon the factors described above. Generally, oral, intravenous, intracerebroventricular and subcutaneous doses of the compounds provided herein for a patient will range from about 0.005 mg per kilogram to about 5 mg per kilogram of body weight per day. In one embodiment, the oral dose of a compound provided herein will range from about 10 mg to about 300 mg per day. In another embodiment, the oral dose of a compound provided herein will range from about 20 mg to about 250 mg per day.

In addition, if the stereochemistry of a structure or a portion of a structure is not indicated with, for example, bold or dashed lines, the structure or portion of the structure is to be interpreted as encompassing all stereoisomers of it or mixtures thereof. Where the compound provided herein contains an alkenyl or alkenylene group, the compound may exist as one of or a mixture of geometric cis/trans (or Z/E) isomers. Where structural isomers are inter-convertible, the compound may exist as a single tautomer or a mixture of tautomers. This can take the form of proton tautomerism in the compound that contains, for example, an imino, keto, or oxime group; or so-called valence tautomerism in the compound that contains, for example, an aromatic moiety. It follows that a single compound may exhibit more than one type of isomerism.
The compounds provided herein may be enantiomerically pure or diastereomerically pure, such as a single enantiomer or a single diastereomer, or be stereoisomeric mixtures, such as a mixture of enantiomers and/or diastereomers, e.g., a racemic or enantioenriched mixture of two enantiomers; or a mixture of two or more diastereomers. In some instances, for compounds that undergo epimerization in vivo, one of skill in the art will recognize that administration of a compound in its (R) form is equivalent to administration of the compound in its (S) form, and vice versa. Conventional techniques for the preparation/isolation of individual enantiomers or diastereomers include synthesis from a suitable optically pure precursor, asymmetric synthesis from achiral starting materials, or resolution of a stereometric mixture, for example, by chiral chromatography, recrystallization, resolution, diastereomeric salt formation, or derivatization into diastereomeric adducts followed by separation.
When the compound provided herein contains an acidic or basic moiety, it may also be provided as a pharmaceutically acceptable salt (See, Berge et al., J. Pharm. Sci. 1977, 66, 1-19; and “Handbook of Pharmaceutical Salts, Properties, and Use,” Stahl and Wermuth, Ed.; Wiley-VCH and VHCA, Zurich, 2002).

Suitable bases for use in the preparation of pharmaceutically acceptable salts, including, but not limited to, inorganic bases, such as magnesium hydroxide, calcium hydroxide, potassium hydroxide, potassium carbonate, zinc hydroxide, sodium hydroxide, or ammonia; and organic bases, such as primary, secondary, tertiary, and quaternary, aliphatic and aromatic amines, including L-arginine, benethamine, benzathine, choline, deanol, diethanolamine, diethylamine, dimethylamine, dipropylamine, diisopropylamine, 2-(diethylamino)-ethanol, ethanolamine, ethylamine, ethylenediamine, isopropylamine, N-methyl-glucamine, hydrabamine, 1H-imidazole, L-lysine, morpholine, 4-(2-hydroxyethyl)-morpholine, methylamine, piperidine, piperazine, propylamine, pyrrolidine, 1-(2-hydroxyethyl)-pyrrolidine, pyridine, quinuclidine, quinoline, isoquinoline, secondary amines, triethanolamine, trimethylamine, triethylamine, N-methyl-D-glucamine, 2-amino-2-(hydroxymethyl)-1,3-propanediol, and tromethamine.
Unless otherwise specified, the term “compound” referred to herein, such as, e.g., a compound of formula (I), (IIa), (IIb), (IIc), (IIIa), (IIIb), (IIIc), (IVa), (IVb), (IVc), (V), or (VI) is intended to encompass one or more of the following: a free base of the compound or a salt thereof, a stereoisomer or a mixture of two or more stereoisomers, a solid form (e.g., a crystal form or an amorphous form) or a mixture of two or more solid forms thereof, or a solvate (e.g., a hydrate) thereof. In certain embodiments, the term “compound” referred to herein is intended to encompass a pharmaceutical acceptable form of the compound, including but not limited to, a free base, a pharmaceutically acceptable salt, a stereoisomer or a mixture of two or more stereoisomers, a solid form (e.g., a crystal form or an amorphous form) or a mixture of two or more solid forms, a solvate (e.g., a hydrate), or a cocrystal thereof.
The compounds used in the methods provided herein can be made by a variety of methods known to the art, including, but not limited to those, disclosed in U.S. Pat. Nos. 8,710,245 and 9,351,954, the contents of which are incorporated herein by reference in their entirety.
The compounds used in the methods provided herein may also be provided as a prodrug, which is a functional derivative of the compound, for example, of Formula (I) and is readily convertible into the parent compound in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent compound. They may, for instance, be bioavailable by oral administration whereas the parent compound is not. The prodrug may also have enhanced solubility in pharmaceutical compositions over the parent compound. A prodrug may be converted into the parent drug by various mechanisms, including enzymatic processes and metabolic hydrolysis.

In various embodiments, the compounds used in the methods provided herein are prepared as a mixture of two or more stereoisomers or diastereoisomers. In one embodiment, the stereoisomers or diastereoisomers are separated using techniques known to those skilled in the art, including but not limited to, chiral column chromatography and chiral resolution by forming a salt with a suitable chiral counterion.
In various embodiments, the compounds used in the methods provided herein are provided as pharmaceutical compositions. Pharmaceutical compositions can be used in the preparation of individual, single unit dosage forms. Pharmaceutical compositions and dosage forms provided herein comprise a compound provided herein, or a pharmaceutically acceptable salt, stereoisomer, clathrate, or prodrug thereof. Pharmaceutical compositions and dosage forms can further comprise one or more excipients.
Pharmaceutical compositions and dosage forms provided herein can also comprise one or more additional active ingredients. Examples of optional second, or additional, active ingredients are also disclosed herein.
Single unit dosage forms provided herein are suitable for oral, mucosal (e.g., nasal, sublingual, vaginal, buccal, or rectal), parenteral (e.g., subcutaneous, intravenous, bolus injection, intramuscular, or intra-arterial), topical (e.g., eye drops or other ophthalmic preparations), transdermal or transcutaneous administration to a patient. Examples of dosage forms include, but are not limited to: tablets; caplets; capsules, such as soft elastic gelatin capsules; cachets; troches; lozenges; dispersions; suppositories; powders; aerosols (e.g., nasal sprays or inhalers); gels; liquid dosage forms suitable for oral or mucosal administration to a patient, including suspensions (e.g., aqueous or non-aqueous liquid suspensions, oil-in-water emulsions, or a water-in-oil liquid emulsions), solutions, and elixirs; liquid dosage forms suitable for parenteral administration to a patient; eye drops or other ophthalmic preparations suitable for topical administration; and sterile solids (e.g., crystalline or amorphous solids) that can be reconstituted to provide liquid dosage forms suitable for parenteral administration to a patient.
The composition, shape, and type of dosage forms will typically vary depending on their use. For example, a dosage form used in the acute treatment of a disease may contain larger amounts of one or more of the active ingredients it comprises than a dosage form used in the chronic treatment of the same disease. Similarly, a parenteral dosage form may contain smaller amounts of one or more of the active ingredients it comprises than an oral dosage form used to treat the same disease. These and other ways in which specific dosage forms are used will vary from one another and will be readily apparent to those skilled in the art. See, e.g., Remington's Pharmaceutical Sciences, 18th Ed., Mack Publishing, Easton Pa. (1990).
In one embodiment, pharmaceutical compositions and dosage forms comprise one or more excipients. Suitable excipients are well known to those skilled in the art of pharmacy, and non-limiting examples of suitable excipients are provided herein. Whether a particular excipient is suitable for incorporation into a pharmaceutical composition or dosage form depends on a variety of factors well known in the art including, but not limited to, the way in which the dosage form will be administered to a patient. For example, oral dosage forms such as tablets may contain excipients not suited for use in parenteral dosage forms. The suitability of a particular excipient may also depend on the specific active ingredients in the dosage form. For example, the decomposition of some active ingredients may be accelerated by some excipients such as lactose, or when exposed to water. Active ingredients that comprise primary or secondary amines are particularly susceptible to such accelerated decomposition. Consequently, provided are pharmaceutical compositions and dosage forms that contain little, if any, lactose other mono- or disaccharides. As used herein, the term “lactose-free” means that the amount of lactose present, if any, is insufficient to substantially increase the degradation rate of an active ingredient.
Lactose-free compositions can comprise excipients that are well known in the art and are listed, for example, in the U.S. Pharmacopeia (USP) 25-NF20 (2002). In general, lactose-free compositions comprise active ingredients, a binder/filler, and a lubricant in pharmaceutically compatible and pharmaceutically acceptable amounts. In one embodiment, lactose-free dosage forms comprise active ingredients, microcrystalline cellulose, pre-gelatinized starch, and/or magnesium stearate.
Also provided are anhydrous pharmaceutical compositions and dosage forms comprising active ingredients, since water can facilitate the degradation of some compounds. For example, the addition of water (e.g., 5%) is widely accepted in the pharmaceutical arts as a means of simulating long-term storage in order to determine characteristics such as shelf-life or the stability of formulations over time. See, e.g., Jens T. Carstensen, Drug Stability: Principles & Practice, 2d. Ed., Marcel Dekker, NY, NY, 1995, pp. 379-80. In effect, water and heat accelerate the decomposition of some compounds. Thus, the effect of water on a formulation can be of great significance since moisture and/or humidity are commonly encountered during manufacture, handling, packaging, storage, shipment, and use of formulations.
Anhydrous pharmaceutical compositions and dosage forms can be prepared using anhydrous or low moisture containing ingredients and low moisture or low humidity conditions. Pharmaceutical compositions and dosage forms that comprise lactose and at least one active ingredient that comprises a primary or secondary amine are preferably anhydrous if substantial contact with moisture and/or humidity during manufacturing, packaging, and/or storage is expected.
An anhydrous pharmaceutical composition should be prepared and stored such that its anhydrous nature is maintained. Accordingly, anhydrous compositions are, in one embodiment, packaged using materials known to prevent exposure to water such that they can be included in suitable formulary kits. Examples of suitable packaging include, but are not limited to, hermetically sealed foils, plastics, unit dose containers (e.g., vials), blister packs, and strip packs.
Also provided are pharmaceutical compositions and dosage forms that comprise one or more compounds that reduce the rate by which an active ingredient will decompose. Such compounds, which are referred to herein as “stabilizers,” include, but are not limited to, antioxidants such as ascorbic acid, pH buffers, or salt buffers.
Like the amounts and types of excipients, the amounts and specific types of active ingredients in a dosage form may differ depending on factors such as, but not limited to, the route by which it is to be administered to patients. In one embodiment, dosage forms comprise a compound provided herein in an amount of from about 0.10 to about 500 mg. In other embodiments, dosage forms comprise a compound provided herein in an amount of about 0.1, 1, 2, 5, 7.5, 10, 12.5, 15, 17.5, 20, 25, 50, 100, 150, 200, 250, 300, 350, 400, 450, or 500 mg.
In other embodiments, dosage forms comprise a second active ingredient in an amount of 1 to about 1000 mg, from about 5 to about 500 mg, from about 10 to about 350 mg, or from about 50 to about 200 mg. Of course, the specific amount of the second active agent will depend on the specific agent used, the diseases or disorders being treated or managed, and the amount(s) of a compound provided herein, and any optional additional active agents concurrently administered to the patient.
Pharmaceutical compositions that are suitable for oral administration can be provided as discrete dosage forms, such as, but not limited to, tablets (e.g., chewable tablets), caplets, capsules, and liquids (e.g., flavored syrups). Such dosage forms contain predetermined amounts of active ingredients, and may be prepared by methods of pharmacy well known to those skilled in the art. See generally, Remington's The Science and Practice of Pharmacy, 21st Ed., Lippincott Williams & Wilkins (2005).
Oral dosage forms provided herein are prepared by combining the active ingredients in an intimate admixture with at least one excipient according to conventional pharmaceutical compounding techniques. Excipients can take a wide variety of forms depending on the form of preparation desired for administration. For example, excipients suitable for use in oral liquid or aerosol dosage forms include, but are not limited to, water, glycols, oils, alcohols, flavoring agents, preservatives, and coloring agents. Examples of excipients suitable for use in solid oral dosage forms (e.g., powders, tablets, capsules, and caplets) include, but are not limited to, starches, sugars, micro-crystalline cellulose, diluents, granulating agents, lubricants, binders, and disintegrating agents.
In one embodiment, oral dosage forms are tablets or capsules, in which case solid excipients are employed. In another embodiment, tablets can be coated by standard aqueous or non-aqueous techniques. Such dosage forms can be prepared by any of the methods of pharmacy. In general, pharmaceutical compositions and dosage forms are prepared by uniformly and intimately admixing the active ingredients with liquid carriers, finely divided solid carriers, or both, and then shaping the product into the desired presentation if necessary.
For example, a tablet can be prepared by compression or molding. Compressed tablets can be prepared by compressing in a suitable machine the active ingredients in a free-flowing form such as powder or granules, optionally mixed with an excipient. Molded tablets can be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent.
Examples of excipients that can be used in oral dosage forms provided herein include, but are not limited to, binders, fillers, disintegrants, and lubricants. Binders suitable for use in pharmaceutical compositions and dosage forms include, but are not limited to, corn starch, potato starch, or other starches, gelatin, natural and synthetic gums such as acacia, sodium alginate, alginic acid, other alginates, powdered tragacanth, guar gum, cellulose and its derivatives (e.g., ethyl cellulose, cellulose acetate, carboxymethyl cellulose calcium, sodium carboxymethyl cellulose), polyvinyl pyrrolidone, methyl cellulose, pre-gelatinized starch, hydroxypropyl methyl cellulose, (e.g., Nos. 2208, 2906, 2910), microcrystalline cellulose, and mixtures thereof.
Suitable forms of microcrystalline cellulose include, but are not limited to, the materials sold as AVICEL-PH-101, AVICEL-PH-103 AVICEL RC-581, AVICEL-PH-105 (available from FMC Corporation, American Viscose Division, Avicel Sales, Marcus Hook, Pa.), and mixtures thereof. A specific example of a binder is a mixture of microcrystalline cellulose and sodium carboxymethyl cellulose sold as AVICEL RC-581. Suitable anhydrous or low moisture excipients or additives include AVICEL-PH-103™ and Starch 1500 LM.
Examples of fillers suitable for use in the pharmaceutical compositions and dosage forms provided herein include, but are not limited to, talc, calcium carbonate (e.g., granules or powder), microcrystalline cellulose, powdered cellulose, dextrates, kaolin, mannitol, silicic acid, sorbitol, starch, pre-gelatinized starch, and mixtures thereof. The binder or filler in pharmaceutical compositions is, in one embodiment, present in from about 50 to about 99 weight percent of the pharmaceutical composition or dosage form.
Disintegrants may be used in the compositions to provide tablets that disintegrate when exposed to an aqueous environment. Tablets that contain too much disintegrant may disintegrate in storage, while those that contain too little may not disintegrate at a desired rate or under the desired conditions. Thus, a sufficient amount of disintegrant that is neither too much nor too little to detrimentally alter the release of the active ingredients may be used to form solid oral dosage forms. The amount of disintegrant used varies based upon the type of formulation, and is readily discernible to those of ordinary skill in the art. In one embodiment, pharmaceutical compositions comprise from about 0.5 to about 15 weight percent of disintegrant, or from about 1 to about 5 weight percent of disintegrant.
Disintegrants that can be used in pharmaceutical compositions and dosage forms include, but are not limited to, agar-agar, alginic acid, calcium carbonate, microcrystalline cellulose, croscarmellose sodium, crospovidone, polacrilin potassium, sodium starch glycolate, potato or tapioca starch, other starches, pre-gelatinized starch, other starches, clays, other algins, other celluloses, gums, and mixtures thereof.
Lubricants that can be used in pharmaceutical compositions and dosage forms include, but are not limited to, calcium stearate, magnesium stearate, mineral oil, light mineral oil, glycerin, sorbitol, mannitol, polyethylene glycol, other glycols, stearic acid, sodium lauryl sulfate, talc, hydrogenated vegetable oil (e.g., peanut oil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil, and soybean oil), zinc stearate, ethyl oleate, ethyl laureate, agar, and mixtures thereof. Additional lubricants include, for example, a syloid silica gel (AEROSIL200, manufactured by W.R. Grace Co. of Baltimore, Md.), a coagulated aerosol of synthetic silica (marketed by Degussa Co. of Plano, Tex.), CAB-O-SIL (a pyrogenic silicon dioxide product sold by Cabot Co. of Boston, Mass.), and mixtures thereof. If used at all, lubricants may be used in an amount of less than about 1 weight percent of the pharmaceutical compositions or dosage forms into which they are incorporated.
In one embodiment, a solid oral dosage form comprises a compound provided herein, and optional excipients, such as anhydrous lactose, microcrystalline cellulose, polyvinylpyrrolidone, stearic acid, colloidal anhydrous silica, and gelatin.
In various embodiments, the active ingredients of compositions used in the methods provided herein and compounds used in the methods provided herein can be administered by controlled release means or by delivery devices that are well known to those of ordinary skill in the art. Examples include, but are not limited to, those described in U.S. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 3,598,123; and 4,008,719, 5,674,533, 5,059,595, 5,591,767, 5,120,548, 5,073,543, 5,639,476, 5,354,556, and 5,733,566, each of which is incorporated herein by reference. Such dosage forms can be used to provide slow or controlled-release of one or more active ingredients using, for example, hydropropylmethyl cellulose, other polymer matrices, gels, permeable membranes, osmotic systems, multilayer coatings, microparticles, liposomes, microspheres, or a combination thereof to provide the desired release profile in varying proportions. Suitable controlled-release formulations known to those of ordinary skill in the art, including those described herein, can be readily selected for use with the active agents provided herein. In one embodiment, provided are single unit dosage forms suitable for oral administration such as, but not limited to, tablets, capsules, gelcaps, and caplets that are adapted for controlled-release.
In one embodiment, controlled-release pharmaceutical products improve drug therapy over that achieved by their non-controlled counterparts. In another embodiment, the use of a controlled-release preparation in medical treatment is characterized by a minimum of drug substance being employed to cure or control the condition in a minimum amount of time. Advantages of controlled-release formulations include extended activity of the drug, reduced dosage frequency, and increased patient compliance. In addition, controlled-release formulations can be used to affect the time of onset of action or other characteristics, such as blood levels of the drug, and can thus affect the occurrence of side (e.g., adverse) effects.
In another embodiment, the controlled-release formulations are designed to initially release an amount of drug (active ingredient) that promptly produces the desired therapeutic or prophylactic effect, and gradually and continually release of other amounts of drug to maintain this level of therapeutic or prophylactic effect over an extended period of time. In one embodiment, in order to maintain a constant level of drug in the body, the drug can be released from the dosage form at a rate that will replace the amount of drug being metabolized and excreted from the body. Controlled-release of an active ingredient can be stimulated by various conditions including, but not limited to, pH, temperature, enzymes, water, or other physiological conditions or compounds.
Parenteral dosage forms can be administered to patients by various routes including, but not limited to, subcutaneous, intravenous (including bolus injection), intramuscular, and intra-arterial. In various embodiments, administration of a parenteral dosage form bypasses patients' natural defenses against contaminants, and thus, in these embodiments, parenteral dosage forms are sterile or capable of being sterilized prior to administration to a patient. Examples of parenteral dosage forms include, but are not limited to, solutions ready for injection, dry products ready to be dissolved or suspended in a pharmaceutically acceptable vehicle for injection, suspensions ready for injection, and emulsions.
Suitable vehicles that can be used to provide parenteral dosage forms are well known to those skilled in the art. Examples include, but are not limited to: Water for Injection USP; aqueous vehicles such as, but not limited to, Sodium Chloride Injection, Ringer's Injection, Dextrose Injection, Dextrose and Sodium Chloride Injection, and Lactated Ringer's Injection; water-miscible vehicles such as, but not limited to, ethyl alcohol, polyethylene glycol, and polypropylene glycol; and non-aqueous vehicles such as, but not limited to, corn oil, cottonseed oil, peanut oil, sesame oil, ethyl oleate, isopropyl myristate, and benzyl benzoate.
Compounds that increase the solubility of one or more of the active ingredients disclosed herein can also be incorporated into the parenteral dosage forms. For example, cyclodextrin and its derivatives can be used to increase the solubility of a compound provided herein. See, e.g., U.S. Pat. No. 5,134,127, which is incorporated herein by reference.
Topical and mucosal dosage forms provided herein include, but are not limited to, sprays, aerosols, solutions, emulsions, suspensions, eye drops or other ophthalmic preparations, or other forms known to one of skill in the art. See, e.g., Remington's The Science and Practice of Pharmacy, 21st Ed., Lippincott Williams & Wilkins (2005); and Introduction to Pharmaceutical Dosage Forms, 4th ed., Lea & Febiger, Philadelphia (1985). Dosage forms suitable for treating mucosal tissues within the oral cavity can be formulated as mouthwashes or as oral gels.
Suitable excipients (e.g., carriers and diluents) and other materials that can be used to provide topical and mucosal dosage forms encompassed herein are well known to those skilled in the pharmaceutical arts, and depend on the particular tissue to which a given pharmaceutical composition or dosage form will be applied. In one embodiment, excipients include, but are not limited to, water, acetone, ethanol, ethylene glycol, propylene glycol, butane-1,3-diol, isopropyl myristate, isopropyl palmitate, mineral oil, and mixtures thereof to form solutions, emulsions or gels, which are non-toxic and pharmaceutically acceptable. Moisturizers or humectants can also be added to pharmaceutical compositions and dosage forms. Examples of additional ingredients are well known in the art. See, e.g., Remington's The Science and Practice of Pharmacy, 21st Ed., Lippincott Williams & Wilkins (2005).
The pH of a pharmaceutical composition or dosage form may also be adjusted to improve delivery of one or more active ingredients. Also, the polarity of a solvent carrier, its ionic strength, or tonicity can be adjusted to improve delivery. Compounds such as stearates can also be added to pharmaceutical compositions or dosage forms to alter the hydrophilicity or lipophilicity of one or more active ingredients so as to improve delivery. In other embodiments, stearates can serve as a lipid vehicle for the formulation, as an emulsifying agent or surfactant, or as a delivery-enhancing or penetration-enhancing agent. In other embodiments, salts, solvates, prodrugs, clathrates, or stereoisomers of the active ingredients can be used to further adjust the properties of the resulting composition.
In one embodiment, active ingredients provided herein are not administered to a patient at the same time or by the same route of administration. In another embodiment, provided are kits which can simplify the administration of appropriate amounts of active ingredients.
In one embodiment, a kit comprises a dosage form of a compound provided herein. Kits can further comprise one or more second active ingredients as described herein, or a pharmacologically active mutant or derivative thereof, or a combination thereof.
In other embodiments, kits can further comprise devices that are used to administer the active ingredients. Examples of such devices include, but are not limited to, syringes, drip bags, patches, and inhalers.
Kits can further comprise cells or blood for transplantation as well as pharmaceutically acceptable vehicles that can be used to administer one or more active ingredients. For example, if an active ingredient is provided in a solid form that must be reconstituted for parenteral administration, the kit can comprise a sealed container of a suitable vehicle in which the active ingredient can be dissolved to form a particulate-free sterile solution that is suitable for parenteral administration. Examples of pharmaceutically acceptable vehicles include, but are not limited to: Water for Injection USP; aqueous vehicles such as, but not limited to, Sodium Chloride Injection, Ringer's Injection, Dextrose Injection, Dextrose and Sodium Chloride Injection, and Lactated Ringer's Injection; water-miscible vehicles such as, but not limited to, ethyl alcohol, polyethylene glycol, and polypropylene glycol; and non-aqueous vehicles such as, but not limited to, corn oil, cottonseed oil, peanut oil, sesame oil, ethyl oleate, isopropyl myristate, and benzyl benzoate.

VII. EXAMPLES

Various embodiments and aspects of the present inventions are further illustrated by the following non-limiting examples.

Example 1: Validation of Transformation Matrix

The robustness and general applicability of the discovery, was investigated by calculating transformed PANSS factor scores for all subjects in 12 additional clinical trials (the “Validation Study” data set) in the lurasidone database that were not included in the analysis sample (PANSS Analysis Study) used to derive the score matrix of FIG. 4 and Table 4A. Included among the 12 additional clinical trials were short-term acute schizophrenia studies, open-label studies, long-term extension studies, and randomized withdrawal studies. For each study in the Validation Data Set, the transformed PANSS factors were evaluated for their total variance (high r-squared values between sums of the transformed PANSS factors vs. PANSS total score), specificity/orthogonality (low correlation between the individual transformed PANSS factors), and high face validity (high correspondence with the Marder PANSS factors).
All study patients were adults with schizophrenia except for D1050301 which was adolescents (13-17 years) with schizophrenia. The PANSS Analysis Study data set alone was used to derive the score matrix (Table 4A) to transform PANSS items in the Validation Data Set into transformed PANSS factor scores.
Transformed PANSS factors were determined, using the same score matrix established from the PANSS Analysis Study data set operating upon the PANSS data od the Validation Set, to determine transformed PANSS factors data for the Validation Data Set, that is:
[PANSS Validation Data]_(N×30)*[UPSM Analysis Study]_(30×7)=[Transformed PANSS Factor Validation Data]_(N×7)
FIG. 5 summarizes the results, for the PANSS Analysis Study dataset (labeled “Analysis” in FIG. 5) and Validation Study dataset (labeled “Validation” in FIG. 5). For each study summarized in FIG. 5, endpoint change scores utilizing the transformed PANSS factors yielded substantially reduced between-factor correlations, regardless of the duration of study treatment (6 weeks to 1 year), or other differences in study design or stage of illness. In addition, a sum of 7 transformed PANSS factors for each patient at endpoint retained over 90% of the variance of untransformed PANSS total.
The transformed PANSS factors also corresponded well to the Marder PANSS factors (r, 0.65-0.94), thus indicating that both factors are measuring very similar schizophrenia symptom domains. Based on the analysis of change, the PANSS negative symptom factor was subdivided into two subfactors, apathy/avolition and deficit of expression (representing these symptom sub-domains), and the PANSS depression/anxiety factor was subdivided into two subfactors, depression and anxiety (representing these symptom sub-domains). The transformed PANSS negative symptom subfactors (apathy/avolition and deficit of expression), correspond to the two subclusters previously identified in a factor analysis by Liemburg et al. (see, J. Psychiatr Res, June 2013; 47(6):718-725). The empirically derived PANSS negative symptom subfactors are also consistent with previously reported differences in the clinical presentation of negative symptoms (see, Blanchard J J, Cohen A S., Schizophr Bull, April 2006; 32(2):238-245) and with reported differences in outcome for each negative symptom phenotype (see, Strauss G P, Horan W P, Kirkpatrick B, et al., J. Psychiatr Res, June 2013; 47(6):783-790). In addition, there is evidence to suggest that these respective negative symptom subfactors may be subserved by distinct neurocircuitry (see, Shaffer J J, Peterson M J, McMahon M A, et al., Mol Neuropsychiatry, December 2015; 1(4):191-200). The transformed PANSS depression/anxiety factor, which separates depression and anxiety as two subfactors, is consistent with the view that these subfactors are partially independent of each other.
The transformed PANSS factors of this Example, derived from the weighted score matrix transformation of PANSS items, were found to meet three important criteria: to have good face validity, to account for almost all of the total variance observed in PANSS total score change, and to exhibit minimal between-factor correlation (high specificity/orthogonality). These criteria were met using the 5 lurasidone clinical trials (PANSS Analysis Study data) used to derive the score matrix transformation. The criteria were also met among the 12 additional lurasidone clinical trials, indicating high cross-study stability and and general applicability. These criteria are discussed more specifically below.
Face validity. Each of the transformed PANSS factors was found to be strongly correlated with Marder PANSS factor scores, with Pearson's r-values at baseline ranging from 0.65-0.94, indicating that each factor is measuring similar efficacy domains.
Total variance. The transformed PANSS factors retained over 90% of the variance contained in the transformed PANSS total score, thus indicating that there was minimum (but quantifiable) loss of information related to total symptom severity using the transformed, transformed PANSS factors. Thus, the sum of transformed PANSS factor scores accurately captured the overall drug treatment effect sizes.
Specificity. A Pearson's correlation analysis of the transformed PANSS factor change scores at week 6 indicated reduced correlations when compared to the Marder PANSS factors, indicating that the transformed PANSS factors are measuring changes somewhat independent of any changes in correlated scores, reducing pseudospecificity concerns. Accordingly, in various embodiments, analyses using these transformed PANSS factors can be used to determine and/or ensure that improvements in one symptom domain are not largely accounted for by improvements in a cross-correlated domain.
Cross-study stability. In the independent validation sample of 12 clinical studies (Validation Study data), the transformed PANSS factor scores, generated using the score matrix, demonstrated similarly low correlations (r<0.25) between the transformed PANSS positive factor change score, and change scores for the other 6 transformed PANSS factors. Notably, the 12 clinical studies used in this Example spanned a diverse range of patient populations, from adolescents, ages 13 to 17 years, to adults, ages 18 to 55 years; and in widely varying geographical regions, including the US, and countries in Europe and Asia. In the analysis of the Validation Study data, the transformed PANSS factors also demonstrated orthogonality and specificity when the score matrix transformation was applied to schizophrenic patient populations, (i.e. patient sub-domains) regardless of whether the patients were acutely ill, chronic, or symptomatically stable. This result indicates that the score matrix formula performs well across studies and across clinical populations, and thus may be pre-specified in the analysis plans.

Example 2: Lurasidone Sub-Domains

The Validation Study data transformed PANSS factors of Example 1 were used to compare treatment effects of an antipsychotic (lurasidone) on established schizophrenia symptom domains with those estimated using Marder PANSS factors. The high degree of total variance explained, effect sizes for the sum of transformed PANSS factors and PANSS total were almost identical (between the transformed PANSS and untransformed PANSS factors), indicating that the estimates of drug effect on schizophrenia symptoms were unchanged between the methods.
FIG. 3A compares baseline to week 6 (within-treatment group) effect sizes for both lurasidone and placebo, as estimated using both the Marder PANSS factors (left panel), and the transformed PANSS factors (right panel). In the left panel, a consistent pattern of moderate-to-high pre-post, within-treatment group, effect sizes (0.5 to 1.1) were observed for lurasidone across all Marder PANSS factors. Pre-post effect sizes for placebo were in the low-to-moderate range across all Marder PANSS factors (effect sizes <0.5, except for the PANSS positive factor change score;
FIG. 3A). For both lurasidone and placebo, the transformed PANSS positive factor (right panel) had an endpoint effect size that was similar in magnitude to the Marder PANSS positive factor (left panel). For the other transformed PANSS factors (disorganized, negative-apathy/avolition and deficit of expression, hostility, and depression and anxiety), the endpoint effect sizes were smaller for both lurasidone and placebo.
FIG. 3B presents for the 5 pooled clinical trials (Analysis Study Data), drug vs. placebo effect sizes for baseline-to-endpoint change were calculated using both the Marder PANSS factors (FIG. 3B; left panel) and the transformed PANSS factors (FIG. 3B, right panel). In the left panel, a relatively consistent pattern of moderate effect sizes (ranging from 0.31 to 0.43) were observed for lurasidone across all Marder PANSS factors. In the right panel, the effect size calculated using the transformed PANSS positive factor was approximately similar to the effect size using the Marder PANSS positive factor (left panel). For the other transformed PANSS factors, the endpoint drug effect sizes were smaller when compared to the same Marder PANSS factors. Endpoint effect sizes calculated for the other transformed PANSS factors (right panel) ranged from 0.05 to 0.29. The endpoint effect size for the transformed PANSS hostility factor was larger than the effect sizes observed in the transformed PANSS disorganized, negative apathy/avolition, deficit of expression, and anxiety/depression factors.
Referring again to FIG. 3B, the effect sizes estimated for positive and hostility symptoms were quite similar between the untransformed PANSS method and the present transformed PANSS method. However, the effect sizes were somewhat lower on negative symptoms of apathy/avolition (r=0.22) and deficit of expression (r=0.04) compared with the effect size observed on Marder negative symptom factor (r=0.35). This appears to be a consequence of reducing the correlation between the PANSS positive and negative factors from r=0.57 to r≤0.10. Effect sizes for the other transformed PANSS factor change scores were also reduced compared with the Marder PANSS factor change scores on the positive (r=0.45 vs. 0.59), disorganized (r=0.23 vs. 0.48), hostility (r=0.31 vs. 0.43), and anxiety (r=0.24 vs. 0.38) and depression (r=0.16 vs. 0.38) factors. In traditional PANSS factor use, effect sizes that are similar across symptom domains may be partly attributable to pseudospecificity. In contrast, measuring efficacy using the transformed PANSS factors, in accord with various embodiments of the present inventions, allows for a clearer understanding of the profile of treatment effects across the symptom domains of schizophrenia.
In addition, it was discovered that increasing the orthogonality of PANSS factors (e.g., by the methods of this Example) revealed an effect of placebo on specific clinical domains of schizophrenia. In spite of the large placebo response, the transformed PANSS hostility factor associated with placebo treatment demonstrated a specific worsening in symptoms of hostility (pre-post effect size, −0.10) and revealed that the apparent improvements in the Marder PANSS factor for hostility was likely due to correlations with improvements in other PANSS items.

Example 3: Application to Compound 129

An embodiment of the methods of the present inventions was applied to PANSS data acquired for Compound 129:
in a study (n=16) of schizophrenic subjects. The study was conducted to test the effects of daily doses of 75 mg Compound 129 for 28 days. PANSS total scores were assessed at baseline (“BL”) pre-dose, Day 1 post-dose and on Days 7, 21, and 28 (endpoint). Each of n=16 subjects were classified into distinct subject sub-population types according to the following classifications, subject sub-populations types, subjects with: (1) prominently positive symptoms (“Positive” group in Tables 5A and 5B; subject ID numbers 35, 48, 28, 44, 34, 30, 53 and 56); (2) prominently disorganized symptoms (“Disorganized” group in Tables 5A and 5B; subject ID number 50); (3) prominently affective symptoms (“Affective” group in Tables 5A and 5B; subject ID numbers 54, 51, 47, and 45); or (4) prominently negative symptoms (“Negative” group in Tables 5A and 5B; subject ID numbers 37, 29, and 49).
Subjects were classified using the UPSM (score matrix) of Table 4A on the PANSS factors assessed at baseline (“BL”) to produce transformed PANSS factors from which subject classification was made. The classifications were determined using the PANSS Analysis Study data for lurasidone, described elsewhere herein, where each of the subjects' (N=1710) PANSS factor scores at baseline were transformed with the UPSM (score matrix) of Table 4A (see, also FIG. 4). Clustering of the subjects (N=1,710) by k-means was used to identify distinct clusters, each characterized by distinctly prominent baseline transformed PANSS factor scores. A SVM (Support Vector Machine) classifier was trained on these cluster assignments at baseline, and subsequently used to identify subject sub-population types post-baseline and in external data sets. These sub-population types (identified using the PANSS Analysis Study data for lurasidone) where used to classify subject sub-population types for the subjects (N=16) of this study on Compound 129, where the UPSM (score matrix) of Table 4A was used to transform the baseline PANSS factor scores of the subjects in this Example 3 to classify the subjects by sub-population type.
Table 5A shows each subjects total PANSS score (based on untransformed PANSS scores) at baseline (pre-dose) and days 1, 7, 14, 21 and 28 (end-point) post-dose. Table 5B shows change from the % baseline of the untransformed PANSS scores at days 1, 7, 14, 21 and 28 (end-point). It is to be understood that a 20% improvement or decrease from baseline 100% scores is generally considered a clinically significant change in acute schizophrenia trials. It was discovered that Compound 129 provided a clinically significant improvement in overall schizophrenia symptoms (untransformed PANSS total) for the subject sub-population with prominent negative symptoms. These results indicate that Compound 129 was a particularly effective treatment in the patient sub-population type characterized by prominent negative symptoms.
The UPSM transformation of the PANSS factor data shows the specificity of treatment effects within the domains of schizophrenia. A drug with treatment effects on a given symptom domain of schizophrenia (e.g., negative symptoms) would be expected to demonstrate overall improvements (PANSS total) in a patient type characterized by more-prominent symptoms in that specific domain (e.g., negative symptoms). Baseline UPSM factor scores can be used to demonstrate specific schizophrenia patient types having prominence of specific symptoms among the 5 dimensions of schizophrenia.
It is to be understood that the score matrix used in this Example was the one determined, as discussed herein, from lurasidone studies (PANSS Analysis Study data) as was the SVM classifier which was trained on PANSS Analysis Study data transformed with the UPSM (score matrix) of Table 4A (see also FIG. 4). That is, the UPSM of Table 4A was shown in this Example to have general applicability to the assessment of the efficacy of schizophrenia treatments on other subject (e.g. patient) groups with other drugs, even though the UPSM of Table 4A (and FIG. 4) was determined using only data from lurasidone studies.

Example 4: Animal Models

Anti-psychotic like activity of the compounds was evaluated in mice using the PCP hyperactivity and Pre-Pulse Inhibition (PPI) models of schizophrenia. Tables 6A and 6B summarize the results.
Methods: Animals: Male C57Bl/6J mice from Jackson Laboratories (Bar Harbor, Me.) were used. Upon receipt, mice were assigned unique identification numbers (tail marked) and were group housed with 4 mice per cage in OptiMICE ventilated cages. All animals remained housed in groups of four during the remainder of the study. All mice were acclimated to the colony room for at least two weeks prior to testing. During the period of acclimation, mice were examined on a regular basis, handled, and weighed to assure adequate health and suitability. Animals were maintained on a 12/12 light/dark cycle. The room temperature was maintained between 20 and 23° C. with a relative humidity maintained between 30% and 70%. Chow and water were provided ad libitum for the duration of the study. In each test, animals were randomly assigned across treatment groups.
PCP Hyperactivity: Open field (OF) chambers were Plexiglas square chambers (27.3×27.3×20.3 cm; Med Associates Inc., St Albans, Vt.) surrounded by infrared photobeams (16×16×16) to measure horizontal and vertical activity. The analysis was configured to divide the open field into a center and periphery zone. Distance traveled was measured from horizontal beam breaks as the mouse moved whereas rearing activity was measured from vertical beam breaks.
Mice were injected with vehicle, test compound, or clozapine (1 mg/kg; i.p) and placed in the OF chambers for 30 min measurement of baseline activity. Mice were then injected with either water or PCP (5 mg/kg; i.p) and placed back in the OF chambers for a 60-minute session. At the end of each OF test session the OF chambers were thoroughly cleaned.
Prepulse Inhibition of Startle: The acoustic startle is an unconditioned reflex response to an external auditory stimulus. Prepulse inhibition of startle (PPI) refers to the reduction in the startle response caused by the presentation of a low-intensity auditory stimulus prior to the startle stimulus. The PPI paradigm is used for the study of schizophrenia and antipsychotic action due to the similarities between the results from human and rodent studies. PPI has been used as a tool for the assessment of deficiencies in sensory-motor gating observed in schizophrenia and to screen for potential antipsychotic drugs. Various psychotomimetic drugs such as PCP can disrupt PPI. In mice, antipsychotic drugs such as clozapine can reverse the disruption of PPI induced by PCP.
Mice were placed in the PPI chambers (Med Associates) for a 5 min session of white noise (70 dB) habituation. After the habituation period the test session was initiated. The session started with a habituation block of 6 presentations of the startle stimulus alone, followed by 10 PPI blocks, each of which consisted of 6 different types of trials. Trial types were: ‘null’ (no stimuli), ‘startle’ (120 dB), ‘startle plus prepulse’ (4, 8 and 12 dB over background noise, i.e., 74, 78 or 82 dB) and ‘prepulse’ (82 dB). Trial types were presented in a random order within each block. Each trial started with a 50 ms stimulus-free period during which baseline movements were recorded. This was followed by a subsequent 20 ms period during which the prepulse stimulus was presented and responses to the prepulse measured. After a further 100 ms period, the startle stimulus was presented for 40 ms and responses recorded for 100 ms from startle onset. Responses were sampled every ms. The inter-trial interval was variable with an average of 15 s (range from 10 to 20 s). In ‘startle’ trials the basic auditory startle response was measured. The basic startle response was calculated as the mean startle response of all ‘startle’ trials (i.e., excluding the first habituation block). In ‘startle plus prepulse’ trials the degree of inhibition of the normal startle was calculated and expressed as a percentage of the basic startle response.
Mice were treated with vehicle, haloperidol (1 mg/kg; i.p) or test compound 30 min prior to PPI test. The PPI enclosures were cleaned following each test.
