Description

    FIELD OF THE INVENTION
  • The present invention relates to methods for the treatment or prevention of fatigue associated with disordered sleep, for example, in multiple sclerosis, Fabry's disease, fibromyalgia, Parkinson's disease, or traumatic brain injury using cyclobenzaprine. The present invention further relates to a biomarker for assessing treatment effects on disordered sleep using cyclobenzaprine.
  • BACKGROUND OF THE INVENTION
  • Cyclobenzaprine, or 3-(5H-dibenzo[a,d]cyclohepten-5-ylidene)-N,N-dimethyl-1-propanamine, was first approved by the U.S. Food and Drug Administration in 1977 for the treatment of acute muscle spasms of local origin. (Katz, W., et al., Cyclobenzaprine in the Treatment of Acute Muscle Spasm: Review of a Decade of Clinical Experience, Clinical Therapeutics 10:216-228 (1988)). Cyclobenzaprine has also been studied in the treatment of fibromyalgia. In a study of 120 fibromyalgia patients, those receiving cyclobenzaprine (10 to 40 mg) over a 12-week period had significantly improved quality of sleep and pain score. There was also a reduction in the total number of tender points and muscle tightness (Bennett R M, et al. A Comparision of Cyclobenzaprine and Placebo in the Management of Fibrositis: A Double-Blind Controlled Study, Arthiritis Rheum. 1988; 31(12):1535-42).
  • Furthermore, the utility of a very low dose cyclobenzaprine as an agent for improving the quality of sleep, as a sleep deepener, or for treating sleep disturbances has been investigated. The very low dosage regimen was viewed as particularly useful in treating sleep disturbances caused by, exacerbated by or associated with fibromyalgia syndrome, prolonged fatigue, chronic fatigue, chronic fatigue syndrome, a sleep disorder, a psychogenic pain disorder, chronic pain syndrome (type II), the administration of a drug, autoimmune disease, stress or anxiety or for treating an illness caused by or exacerbated by sleep disturbances, and symptoms of such illness and generalized anxiety disorder. See U.S. Pat. Nos. 6,395,788 and 6,358,944, herein incorporated by reference.
  • It is important to develop new methods and pharmaceutical compositions that ameliorate fatigue associated with disordered sleep to improve symptoms found in fibromyalgia, multiple sclerosis, Fabry's disease, traumatic brain injury or Parkinson's disease.
  • SUMMARY OF THE INVENTION
  • In one aspect the invention is a method for treating or preventing fatigue associated with a sleep disorder associated with fibromyalgia, multiple sclerosis, Fabry's disease, traumatic brain injury or Parkinson's disease. The method comprises administering to a human in need of such treatment a pharmaceutical composition comprising cyclobenzaprine in a therapeutically effective amount and a therapeutically effective carrier, wherein such treatment ameliorates or eliminates the symptoms. The cyclobenzaprine may be administered at a dose between 0.1 mg to 50 mg/day. In one embodiment the cyclobenzaprine is administered at a low dose of less than 5 mg/day, such 1 mg/day or 2.5 mg/day. In another embodiment, the cyclobenzaprine may be administered at doses between 5 mg and 12 mg/day, such as 7 mg/day or 10 mg/day.
  • The method may further entail administering sequentially or concurrently a drug selected from the group consisting of an alpha-1-adrenergic receptor antagonist, a beta-adrenergic antagonist, an anticonvulsant, a selective serotonin reuptake inhibitor or a serotonin-norepinephrine reuptake inhibitor. Exemplary drugs include prazosin, sertraline, paroxetine, fluoxetine, citalopram and escitalopram.
  • In another aspect, the invention is a method for relieving muscle spasticity encountered in multiple sclerosis or Parkinson's disease. The method comprises administering cyclobenzaprine to relieve the spasticity. The cyclobenzaprine may be administered at a dose between 0.1 mg to 50 mg/day. In one embodiment, cyclobenzaprine is administered at a low dose of less than 5 mg/day, such 1 mg/day or 2.5 mg/day. In another embodiment, the cyclobenzaprine may be administered at doses higher between 5 mg and 12 mg/day, such as 7 mg/day or 10 mg/day.
  • In yet another aspect, the invention is a biomarker or method for monitoring the effectiveness of a cyclobenzaprine treatment for disordered sleep. The method comprises determining CAP A1, A2 and A3 rates, and calculating an nCAP A2+A3 (or CAPA2+A3(Norm)) value to determine whether a specified CAPA2+A3(Norm) threshold is achieved. When the specified CAPA2+A3(Norm) threshold is achieved the cyclobenzaprine treatment is considered effective. Typically the threshold is CAPA2+A3(Norm)≦33%, such 10%, 15%, 20%, 25%, 30% or 33%.
  • DETAILED DESCRIPTION OF THE INVENTION
  • In one aspect the invention is a method for treating fatigue associated with disordered sleep in conditions characterized by chronic fatigue including multiple sclerosis, fibromyalgia, Parkinson's disease, Fabry's disease, or traumatic brain injury. We have shown that improvement in fatigue is strongly associated with normalization of disordered sleep and that cyclobenzaprine normalizes disordered sleep. This normalization of sleep is measured by cyclic alternating pattern (CAP) analysis. Fatigue and disordered sleep may be symptoms of diseases including fibromyalgia, traumatic brain injury, Parkinson's disease, Fabry's disease, or multiple sclerosis. Traumatic brain injury and multiple sclerosis have muscle spasticity components that cyclobenzaprine can target along with disordered sleep and fatigue.
  • Furthermore, we have identified a biomarker for investigating the effectiveness of cyclobenzaprine treatment for fatigue associated with disordered sleep. Specifically, we have identified CAPA2+A3(Norm)≦33% as a threshold for effectiveness for cyclobenzaprine treatment. The method entails measuring CAPA1, CAPA2 and CAPA2 at different times or doses during treatment. CAPA2+A3(Norm) is then determined to identify whether a cyclobenzaprine treatment course is effective.
  • Fatigue may be defined as: “The awareness of a decreased capacity for physical and/or mental activity due to an imbalance in the availability, utilization, and/or restoration of resources needed to perform activity” (Aaronson, et al. (1999). Defining and measuring fatigue. Image J Nurs Sch 31(1): 45-50). Fatigue is commonly measured by rating scales such as the Fatigue Impact Scale.
  • CAP is a sleep EEG measurement consisting of transient arousals (phase A) that periodically interrupt the tonic theta/delta activities of NREM sleep (phase B) (Terzano, Parrino et al. (1996). Polysomnographic analysis of arousal responses in obstructive sleep apnea syndrome by means of the cyclic alternating pattern J Clin Neurophysiol 13(2): 145-55). Functionally, CAP translates a condition of sustained arousal instability oscillating between a greater arousal level (phase A) and a lesser arousal level (phase B). Arousal can be considered as a short transient intrusion of wakefulness EEG rhythms into sleep. An increased level of arousability might be related to sleep fragmentation. CAP is a spontaneous rhythm detectable during NREM sleep in form of EEG amplitude oscillations composed of an EEG transient pattern (phase A of the cycle) separated by intervals of background activity (phase B of the cycle). Three main EEG patterns have been described according to the prevalence of EEG synchrony (subtype A1, or CAPA1), prevalence of EEG desynchrony (subtype A3, or CAPA3), or a combination of both (subtype A2, or CAPA2) (Terzano, Parrino et al. (2001, 2002). Atlas, rules, and recording techniques for the scoring of cyclic alternating pattern Sleep Med., 2(6) 537-553 and 3(2) 187-199).
  • “Cyclobenzaprine” includes cyclobenzaprine or a metabolite thereof, prodrug of cyclobenzaprine, a metabolite thereof, or a compound related to cyclobenzaprine. Metabolites of cyclobenzaprine useful according to the methods of this invention are metabolites that have substantially the same activity or better as cyclobenzaprine in alleviating symptoms. Cyclobenzaprine metabolites that may be useful according to this invention include CBP 10,11-trans-dihydriol, N-desmethyl-2-hydroxycyclobenzaprine, 3-hydroxycyclobenzaprine, N-desmethylcyclobezaprine, cyclobenzaprine N-oxide or a chiral isomer of these metabolites. A prodrug of cyclobenzaprine is a derivative of cyclobenzaprine that is metabolized in vivo into the active agent. Prodrugs useful according to this invention are those that have substantially the same activity or better than cyclobenzaprine in treating or preventing the symptoms of fibromyalgia, multiple sclerosis, Fabry's disease, traumatic brain injury or Parkinson's disease. Methods for making prodrugs are readily known in the art (e.g., Balant, L. P., Prodrugs for the Improvement of Drug Absorption Via Different Routes of Administration, Eur. J. Drug Metab. Pharmacokinet. 15:143-153 (1990); and Bundgaard, H., Novel Chemical Approaches in Prodrug Design, Drugs of the Future 16:443-458 (1991); incorporated by reference herein). A compound related to cyclobenzaprine is a compound with substantially the same activity as cyclobenzaprine, such as amitryptyline or nortriptyline.
  • As used herein, a “therapeutically effective amount” of cyclobenzaprine for the purposes of this invention refers to the amount of the compound that prevents or alleviates or eliminates or interferes with disordered sleep. A physician can readily determine when symptoms are prevented or alleviated or eliminated, for example through clinical observation of a subject, or through reporting of symptoms by the subject during the course of treatment. One skilled in the art can readily determine an effective amount of a cyclobenzaprine to be administered, by taking into account factors such as the size, weight, age and sex of the subject, the extent of disease penetration or persistence and severity of symptoms, and the route of administration. Generally, a therapeutically effective amount of cyclobenzaprine administered to a subject is between 0.1 mg to about 50 mg/day, between 0.5 to about 12 mg/day, between 1 mg and 12 mg/day, or between 1 and 4 mg/day. Higher or lower doses are also contemplated.
  • In one embodiment the cyclobenzaprine is administered at a very low dose to minimize side effects observed at higher doses. The low doses include doses of less than 5 mg/day or less than 2.5 mg/day. Even lower doses are also contemplated. Generally, cyclobenzaprine therapy can be carried out indefinitely to alleviate the symptoms of interest and frequency of dosage may be changed to be taken as needed. The period of treatment should be carried out for as long as necessary to alleviate one or more of fibromyalgia, multiple sclerosis, Fabry's disease, traumatic brain injury or Parkinson's disease symptoms and the cyclobenzaprine administered at night-time and at an appropriate dose.
  • In another embodiment of the invention, cyclobenzaprine is administered in combination with a drug which may further alleviate the symptoms of fatigue. The drugs may be administered sequentially or concurrently with the cyclobenzaprine. The drugs include an alpha-1-adrenergic receptor antagonist, a beta-adrenergic antagonist, an anticonvulsant, a selective serotonin reuptake inhibitor or a serotonin-norepinephrine reuptake inhibitor. Exemplary selective serotonin reuptake inhibitor or a serotonin-norepinephrine reuptake inhibitor include, but are not limited to, buproprion (at a dose between about 105 mg and 450 mg/day), citalopram (at a dose between about 10 mg and 40 mg/day), desvenlafaxine (at a dose between about 50 mg and 400 mg/day), duloxetine (at a dose between about 40 mg and120 mg/day), escitalopram (at a dose between about 10 mg and 20 mg/day), fluoxetine (at a dose between about 20 mg and 80 mg/day), fluvoxamine (at a dose between about 100 mg and 300 mg/day), milnacipran (at a dose between about 30 mg and 200 mg/day), paroxetine (at a dose between about 20 mg and 50 mg/day), sertraline (at a dose between about 50 mg and 200 mg/day), tradodone (at a dose between about 150 mg and 600 mg/day), and venlafaxine (at a dose between about 75 mg and 225 mg/day), Exemplary anticonvulsants include, but are not limited to carbamazepine (at a dose between about 400 mg and 1200 mg/day), gabapentin (at a dose between about 900-1800 mg/day), lamotrigine (at a dose between about 100 mg and 400 mg/day), oxcarbazepine (at a dose between about 1200 mg and 2400 mg/day), pregabalin (at a dose between about 150 mg and 600 mg/day), tiagabine (at a dose between about 32 mg and 56 mg/day), topiramate (at a dose between about 200 mg and 400 mg/day), and valproate (at a dose between about 1200 mg and 1500 mg). Exemplary alpha-1-adrenergic receptor antagonists include, but are not limited to, prazosin administered at a dose of between about 0.5 mg to 15 mg/day.
  • In a further aspect, the invention is a pharmaceutical composition. The pharmaceutical composition comprises a therapeutically effective amount of cyclobenzaprine in combination with a drug selected from the group consisting of an alpha-1-adrenergic receptor antagonist, a beta-adrenergic antagonist, and an anticonvulsant. Generally, the amount of cyclobenzaprine in the pharmaceutical composition is between 0.1 mg to about 50 mg, between 0.5 to about 30 mg, or between 1 mg and 20 mg. Higher or lower doses are also contemplated. In one particular embodiment the amount of cyclobenzaprine is low to minimize side effects observed with higher amounts. The very low amounts are of less than 10 mg, less than 7 mg or less than 5 mg or less than 2.5 mg per day. Even lower amounts are also contemplated. In another embodiment of the invention, cyclobenzaprine is combined with a drug which may further alleviate the symptoms of fibromyalgia, multiple sclerosis, traumatic brain injury, Fabry's disease or Parkinson's disease. The drugs include an alpha-1-adrenergic receptor antagonist, a beta-adrenergic antagonist, an anticonvulsant, a selective serotonin reuptake inhibitor or a serotonin-norepinephrine reuptake inhibitor. Exemplary anticonvulsants include, but are not limited to carbamazepine (400 mg to 1200 mg), gabapentin (900 mg to 1800 mg), lamotrigine (100 mg to 400 mg), oxcarbazepine (1200 mg to 2400 mg), pregabalin (150 mg to 600 mg), tiagabine (32 mg to 56 mg), topiramate (200 mg to 400 mg), and valproate (1200 mg to 1500 mg). An exemplary alpha-1-adrenergic receptor antagonists includes, but is not limited to, prazosin in the amount of 0.5 mg to 15 mg. An exemplary selective serotonin reuptake inhibitor is escitalopram (in the amount of 10 mg and 20 mg).
  • Any suitable route of administration may be employed for providing the patient with an effective dosage of cyclobenzaprine. For example, buccal, oral, rectal, parenteral, transdermal, subcutaneous, sublingual, intranasal, intramuscular, intrathecal and the like may be employed as appropriate. The term parenteral as used herein includes subcutaneous, intracutaneous, intravenous, intramuscular, intra-articular, intrasynovial, intrasternal, intrathecal, intralesional and intracranial injection or infusion techniques. Dosage forms include tablets, such as scored tablets, coated tablets, or orally dissolving tablets; thin films, caplets, capsules (e.g. hard gelatin capsules), troches, dragees, dispersions, suspensions, solutions, patches and the like, including sustained release formulations well known in the art. In one preferred embodiment, the dosage form is an orally dissolving tablet or a thin film.
  • By “pharmaceutically acceptable carrier” is meant any diluent or excipient that is compatible with the other ingredients of the formulation, and which is not deleterious to the recipient. The pharmaceutically acceptable carrier can be selected on the basis of the desired route of administration, in accordance with standard pharmaceutical practices. Pharmaceutical compositions of the invention for parenteral administration can take the form of an aqueous or nonaqueous solution, dispersion, suspension or emulsion. In preparing pharmaceutical compositions of the invention for parenteral administration, cyclobenzaprine can be mixed with a suitable pharmaceutically acceptable carrier such as water, oil (particularly a vegetable oil), ethanol, saline solutions (e.g., normal saline), aqueous dextrose (glucose) and related sugar solutions, glycerol, or glycols such as propylene glycol or polyethylene glycol. Pharmaceutical compositions of the invention for parenteral administration preferably contain a water-soluble salt of cyclobenzaprine. Stabilizing agents, antioxidizing agents and preservatives can also be added to the pharmaceutical compositions for parenteral administration. Suitable antioxidizing agents include sulfite, ascorbic acid, citric acid and its salts, and sodium EDTA. Suitable preservatives include benzalkonium chloride, methyl- or propyl-paraben, and chlorbutanol.
  • In preparing pharmaceutical compositions of the invention for oral administration, cyclobenzaprine can be combined with one or more solid or liquid inactive ingredients to form tablets, capsules, pills, powders, granules or other suitable oral dosage forms. For example, cyclobenzaprine can be combined with at least one pharmaceutically acceptable carrier such as a solvent, filler, binder, humectant, disintegrating agent, solution retarder, absorption accelerator, wetting agent absorbent or lubricating agent. In one embodiment, cyclobenzaprine is combined with carboxymethylcellulose calcium, magnesium stearate, mannitol or starch, and is formed into tablets by conventional tableting methods.
  • Pharmaceutical compositions of the invention can be formulated so as to provide lymphatic absorption including pre-micellar and micellar mixtures to provide faster absorption in the small-intestine than the immediate release tablets or capsules through oral/GI route and to reduce or potentially bypass first-pass hepatic metabolism of cyclobenzaprine, for example by cytochrome P-450 3A4 as a CYP3A substrate, demethylation to norcyclobenzaprine (also known as desmethylcyclobenzaprine), or by glucuronidation (such as to cyclobenzaprine-N+-glucuronidate). Preferably, a controlled-release pharmaceutical composition of the invention is capable of releasing cyclobenzaprine into a subject at a rapid onset, so as to maintain a substantially constant or desired pharmacological activity for a given period of time, reduce or remove the effect of food on absorption, and to provide elimination of the drug and metabolites from the body with a reduced terminal elimination phase.
  • Pharmaceutical compositions of the invention can be formulated so as to provide buccal absorption including thin film formulations and orally dissolving tablets to provide faster absorption than the oral/GI route and to reduce or potentially bypass first-pass hepatic metabolism of cyclobenzaprine, for example by cytochrome P-450 3A4 as a CYP3A substrate, demethylation to norcyclobenzaprine (also known as desmethylcyclobenzaprine), or by glucuronidation (such as to cyclobenzaprine-N+-glucuronidate). Preferably, a controlled-release pharmaceutical composition of the invention is capable of releasing cyclobenzaprine into a subject at a rapid onset, so as to maintain a substantially constant or desired pharmacological activity for a given period of time, reduce or remove the effect of food on absorption, and to provide elimination of the drug and metabolites from the body with a reduced terminal elimination phase.
  • Pharmaceutical compositions of the invention can also be formulated so as to provide controlled-release of cyclobenzaprine upon administration of the composition to a subject. Preferably, a controlled-release pharmaceutical composition of the invention is capable of releasing cyclobenzaprine into a subject at a desired rate, so as to maintain a substantially constant or desired pharmacological activity for a given period of time. As used herein, a “controlled-release component” is a compound such as a lipid or mixture of lipids, liposome and/or microsphere that induces the controlled-release of cyclobenzaprine into the subject upon exposure to a certain physiological compound or condition. For example, the controlled-release component can be biodegradable, activated by exposure to a certain pH or temperature, by exposure to an aqueous environment, or by exposure to enzymes.
  • Formulation of controlled-release pharmaceutical compositions of the invention is within the skill in the art. Controlled release formulations suitable for use in the present invention are described in, for example, U.S. Pat. No. 5,674,533 (liquid dosage forms), U.S. Pat. No. 5,591,767 (liquid reservoir transdermal patch), U.S. Pat. No. 5,120,548 (device comprising swellable polymers), U.S. Pat. No. 5,073,543 (ganglioside-liposome vehicle), U.S. Pat. No. 5,639,476 (stable solid formulation coated with a hydrophobic acrylic polymer), the entire disclosures of which are herein incorporated by reference.
  • Biodegradable microparticles can also be used to formulate controlled-release pharmaceutical compositions suitable for use in the present invention, for example as described in U.S. Pat. Nos. 5,354,566 and 5,733,566, the entire disclosures of which are herein incorporated by reference.
  • In one embodiment, controlled-release pharmaceutical compositions of the invention comprise cyclobenzaprine and a controlled-release component. As used herein, a “controlled-release component” is a compound such as a polymer, polymer matrix, gel, permeable membrane, liposome and/or microsphere that induces the controlled-release of cyclobenzaprine into the subject upon exposure to a certain physiological compound or condition. For example, the controlled-release component can be biodegradable, activated by exposure to a certain pH or temperature, by exposure to an aqueous environment, or by exposure to enzymes. An example of a controlled-release component which is activated by exposure to a certain temperature is a sol-gel. In this embodiment, cyclobenzaprine is incorporated into a sol-gel matrix that is a solid at room temperature. This sol-gel matrix is implanted into a subject having a body temperature high enough to induce gel formation of the sol-gel matrix, thereby releasing the active ingredient into the subject.
  • In one embodiment, pharmaceutical compositions of the invention may comprise cyclobenzaprine and components that form micelles. Micelles containing cyclobenzaprine in the stomach and proximal small intestine facilitate absorption. Example of a micelle-component which is activated by exposure to a certain temperature is found in U.S. Pat. Nos. 6,761,903; 6,720,001; 6,383,471; 6,309,663; 6,267,985; and 6,248,363, incorporated herein by reference. In this embodiment, cyclobenzaprine is incorporated into a soft-gel capsule. Such components may mimic the augmentation of absorption termed the “food effect”, and such formulations may provide more predictable absorption by eliminating the “food effect” from dietary sources.
  • The composition of this invention may be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other solubilizing or dispersing agents known in the art.
  • The magnitude of a prophylactic or therapeutic dose of the active ingredient (i.e., cyclobenzaprine or metabolite thereof) in the prevention or treatment of a human will vary with the type of affliction, the severity of the patient's affliction and the route of administration. The dose and dose frequency will also vary according to the age, weight and response of the individual patient. In a preferred embodiment, one dose is given at bed time or up to several hours before bedtime to facilitate the achievement of deep, refreshing sleep. Bedtime may be any hour of the day at which a person engages in the most extensive period of sleep.
  • In order that this invention to be more fully understood, the following examples are set forth. These examples are for the purpose of illustration only and are not to be construed as limiting the scope of the invention in any way. The practice of the invention is illustrated by the following non-limiting examples.
  • EXAMPLES Example 1 Tablet Formulation
  • A typical oral formulation for coated tablets consists of the following:
  • Formula quantity per tablet (mg.) cyclobenzaprine 1.0, lactose 74.0, corn starch 35.0, water (per thousand tablets) 30.0 ml, magnesium stearate 1.0, corn starch 25.0 The active ingredient (cyclobenzaprine) is blended with the lactose until a uniform blend is formed. The smaller quantity of corn starch is blended with a suitable quantity of water to form a corn starch paste. This is then mixed with the uniform blend until a uniform wet mass is formed. The remaining corn starch is added to the resulting wet mass and mixed until uniform granules are obtained. The granules are then screened through a suitable milling machine, using a ¼ inch stainless steel screen. The milled granules are then dried in a suitable drying oven until the desired moisture content is obtained. The dried granules are then milled through a suitable milling machine using ¼ mesh stainless steel screen. The magnesium stearate is then blended and the resulting mixture is compressed into tablets of desired shape, thickness, hardness and disintegration.
  • Tablets are coated by standard aqueous or nonaqueous techniques. For example, 2.5 mg of hydroxypropymethylcellulose can be dissolved in 25 mg of deionized water. An aqueous (10 mg) suspension of 1.88 mg talc, 0.5 mg of titanium dioxide, 0.1 mg of yellow iron oxide, and 0.02 mg of red iron oxide is stirred into this solution. The coating suspension is sprayed on the tablets and the coated tablets are dried overnight at 45° C.
  • Example 2 Development of an Optimized Gelcap Formulation of VLD Cyclo for Fatigue
  • We are developing a novel gelcap that employs a specific mixture of lipids to form micelles containing cyclobenzaprine that is expected to speed upper GI absorption, increase efficiency of absorption (in stomach and proximal small intestine); decrease or eliminate food effect (which is 20% for the Amrix formulation of cyclobenzaprine) and speed elimination (since lower GI absorption may prolong the terminal elimination phase in existing formulations). The gelcap formulation is expected to result in increased dosage precision; decreased potential for morning “hangover”; and potentially more rapid induction of sleep.
  • The lipid formulation is designed to form micelles in gastric-intestinal fluids, to solubilize cyclobenzaprine in the stomach and small intestine and to increase the rate, efficiency and predictability of absorption of cyclobenzaprine in the bloodstream. Cyclobenzaprine assumes a positive charge in the acidic gastric fluid. Micelles and charged cyclobenzaprine are highly soluble in gastric fluid. In the small intestine, the pH increases and cyclobenzaprine starts to lose its charge. Uncharged cyclobenzaprine molecules have poor solubility without micelles. The micelles prevent precipitation of the uncharged cyclobenzaprine by solubilizing it in their cores and to deliver the cyclobenzaprine to the wall of the small intestine where the cyclobenzaprine can be absorbed into the bloodstream. The lipid formulation is referred to as pro-micellar because prior to interacting with aqueous fluid, the lipids do not form micelles. The pro-micellar mixtures are typically encased in a gelatin capsule (gelcap).
  • Example 3 Cyclic Alternating Pattern Analysis VLD CBP Effects on CAP A2+CAP A3
  • Subsequent to enrollment and completion, EEG sleep studies in FM patients were reported that identified increases in the periodic sleep EEG arousal disorder known as the cyclic alternating pattern (CAP) in non-REM sleep. (Rizzi et al. J. Rheumatol. 2004, 31(6):1193-1199, Rosa et al. 1999, 110(4):585-592). Therefore, an analysis of sleep EEG CAP was performed that measured subtypes CAP A1, CAP A2, and CAP A3 and Total CAP (or CAP A1+A2+A3). Subtype CAP A1 is associated with sleep maintenance or least sleep instability, and subtypes CAP A2 and A3 are associated with moderate to prominent increases in sleep instability.
  • Because CAP A2 and A3 are most closely associated with sleep instability26, 27, the sum of CAPA2+CAPA3 rates (CAPA2+A3) was used as an indicator of disordered sleep. CAPA2+A3 was normalized (CAPA2+A3(Norm)) by dividing CAPA2+A3 by the total CAP rate (CAPtotal=CAPA1+CAPA2+CAPA3 rates=CAPA1+A2+A3) and expressed as a percentage. Therefore, CAPA2+A3(Norm)=100*CAPA2+A3/CAPA1+A2+A3 and this reflects the percentage of total CAP that is associated with sleep instability.
  • To determine whether patients experienced nights with a potential CAP response to treatment, it was necessary to determine an empirical threshold below which CAPA2+A3(Norm) values reflect a night of relatively stable sleep for this population. To determine a threshold for CAPA2+A3(Norm) that could be informative for a potential treatment response, the study CAP data were then evaluated by considering a range of cutoff values for CAPA2+A3(Norm) from ≦10% to ≦50%. Testing various nCAPA2+A3 values revealed that defining a threshold for response CAPA2+A3(Norm)≦33% distinguished VLD CBP-treated subjects from placebo-treated subjects at which threshold, the percentage of patients with increased nights of CAP response while on treatment (ITT, LOCF) was 72% with VLD CBP vs. 33% with placebo (p=0.019).
  • Correlation of CAPA2+A3(Norm) with FM Symptoms. To evaluate whether increased nights with CAPA2+A3(Norm)≦33% was correlated with clinical improvement measures in pain, fatigue, tenderness, HAD, and HAD depression, over the course of the study (LOCF week 8), Spearman's rank correlation was then investigated separately for each treatment. Data were coded such that improvements were positive. Within the VLD CBP treated patients, increased nights with CAPA2+A3(Norm)≦33% was correlated positively to decreases in fatigue (rho=0.62, p=0.006), HAD total score (rho=0.505, p=0.033), HAD depression subscale (rho=0.556, p=0.017), patient-rated fatigue (rho=0.614, p=0.007) and clinician-rated fatigue (rho=0.582, p=0.0112). In contrast, improved CAP response was not correlated with either musculoskeletal pain or dolorimetry. Within the Placebo-treated subjects, none of these FM symptoms or Sleep EEG parameters was significantly correlated to increased number of nights with CAPA2+A3(Norm)≦33%. In the placebo group, increased nights of CAP response correlated with measures of improved sleep: a positive correlation with sleep efficiency and a negative correlation with total time awake. Together, these findings show that nights with CAPA2+A3(Norm)≦33% reflect relatively healthy or restorative sleep for FM patients as symptoms vary naturally over the course of the condition, as well as providing a potential biomarker for treatment effects of low dose cyclobenzaprine for disordered sleep.
  • Example 4 Treatment of Multiple Sclerosis
  • A 46 year old woman was diagnosed with multiple sclerosis three years ago. Her last flare-up was treated with a short course of steroids, and she has been symptom free for two months. However, she has noted that throughout the day she has very low energy levels. Her capacity for physical and mental work has declined to the point where she is unable to function at work. She reports getting 6 to 8 hours of sleep each night but feels unrefreshed in the morning. Taking naps or getting more sleep does nothing to improve her energy level. She began taking cyclobenzaprine initially at a dose of 2 mg at bedtime. Her doctor increased the dose to 4 mg at bedtime. With each does she felt that the quality of her sleep improved and her level of energy increased during the day. Within three weeks, her physical stamina as well as her ability to concentrate and focus increased to the extent that she was able to resume occupational functioning. Her doctor asks her to assess her level of fatigue on a scale of 1 to 10 before and after cyclobenzaprine treatment. Before treatment she assessed herself as having 9/10 fatigue. After treatment her level of fatigue decreased to 3/10.
  • Example 5 Treatment of Traumatic Brain Injury
  • A 27-year-old male survived a serious motor vehicle accident with closed head trauma. He underwent six months of physical rehabilitation. However, he was left with mild spasticity and hyper-reflexia of the upper extremities, general cognitive slowing, and mild language difficulties. Other symptoms including pronounced emotional lability often manifested as outbursts of anger or uncontrollable crying spells. These symptoms were felt by his neurologist to be consistent with traumatic brain injury. Because of the spasticity, the neurologist recommended six months of additional physical rehabilitation. However, the patient was unable to make progress with his physical rehabilitation because his physical energy level and motivation would drop very rapidly during the course of his rehabilitation sessions. He was unable to complete many of the exercises or follow complex instructions. If sleep is poor or, characterized by both difficulty falling asleep and early-morning awakening. His neurologist prescribed cyclobenzaprine at a dose of 5 mg at bedtime. Within three weeks, the patient's sleep improved substantially and his level of energy and concentration were markedly better. He was able to complete rehabilitation and make significant gains in physical capacity.
