Description

FAVORABLE MODULATION OF FfEALTH-RELATED QUALITY OF LIFE AND
HEALTH-RELATED QUALITY-ADJUSTED TIME-TO-PROGRESSION OF
DISEASE IN PATIENTS WITH PROSTATE CANCER
TECHNICAL FIELD This invention is directed to a method for favorably modulating the health-related quality of life and the health-related quality-adjusted time-to-disease progression in a patient with prostate cancer and a method for measuring of the health-related quality-adjusted time-to-disease progression in a patient with prostate cancer.
BACKGROUND OF THE INVENTION Prostate cancer patients often face poor prognosis, limited treatment options, and a decline in their health-related quality of life (QoL) with disease progression. Because conventional analyses of responses in prostate cancer trials fail to account for the effect of treatment on a patient's self-perception of their health status and general well-being, qualitative and quantitative evaluation of the multidimensional health-related QoL responses of the patient over time could potentially provide a more comprehensive assessment and understanding of the benefit of a given therapeutic intervention. Thus, there is a long-standing need in the art for a method of favorably modulating the health-related QoL and the health-related quality-adjusted time-to-progression (QATTP) of disease in patients with prostate cancer and a method for measuring the health-related QATTP of disease in patients undergoing treatment for prostate cancer.
DISCLOSURE OF THE INVENTION
A first embodiment of this invention, therefore, is directed to a method for favorably modulating the health-related QoL of a patient with prostate cancer comprising administering thereto a therapeutically effective amount of an endothelin (ET) receptor antagonist. A second embodiment of this invention is directed to a method for favorably modulating the health-related QATTP of disease of a patient with prostate cancer comprising administering thereto a therapeutically effective amount of an ET receptor antagonist.
As used herein, the following terms have the meanings ascribed. The term "endothelin receptor antagonist" means a compound which binds to the endothelin receptor, which binding may be evaluated by the ability of the compound to inhibit endothelin from binding to its receptor, which inhibition is preferably between about 50%- 100% at 1 μm inhibitor concentration, more preferably about 80%- 100% at 1 μm inhibitor concentration, most preferably about 95%-100% at 1 μm inhibitor concentration. The term "favorably modulating" means sustaining and/or improving the health-related QoL and/or sustaining and/or improving and/or extending the health-related QATTP of disease in a patient with prostate cancer.
The term "quality-adjusted time-to-progression of disease" or "QATTP of disease" means the interval between the initiation of chemotherapy in a patient with prostate cancer to the time of disease progression adjusted by the patient's health-related QoL score.
The term "health-related quality of life" or "health-related QoL" means domains comprising physical functioning, emotional functioning, social/family functioning, role functioning, cognitive functioning, self-perception, and other domains for patients with prostate cancer, the other domains comprising pain, fatigue, nausea and vomiting, change in appetite, dyspnea, sleep disturbance, diarrhea, constipation, urinary function, and change in weight.
A third embodiment of this invention is directed to a method for determining modulation of the health-related QATTP of disease in a patient undergoing endothelin antagonist chemotherapy for prostate cancer, the method comprising the steps of:
(a) providing a patient population, in which the patient population comprises at least one patient with prostate cancer, preferably about 100 patients with prostate cancer, more preferably about 150 patients with prostate cancer, most preferably about 280 patients with prostate cancer;
(b) administering to each member of the patient population either a therapeutically effective amount of an ET receptor antagonist or placebo, in which ET receptor antagonist favorably modulates, preferably sustains and/or extends, more preferably improves and/or extends, the health-related QATTP of disease of a patient with prostate cancer; (c) measuring the health-related QoL domains of each patient over a period of time to provide a health-related QATTP of disease for each patient in the patient population, in which the period of time is at least one interval time period between the beginning and end of the treatment, preferably about five to about seven weeks after the beginning of treatment, more preferably about six weeks after the beginning of the treatment; and
(d) determining the health-related QATTP for each health-related QoL domain and the sum of the mean or median health-related QATTP's of disease for the patient population.
A fourth embodiment of this invention is directed to a method for increasing the survival time of a patient with prostate cancer comprising administering thereto a therapeutically effective amount of an ET receptor antagonist.

The ET receptor antagonists of this invention comprise asymmetrically substituted carbon atoms in the R or S configuration, in which the terms "R" and "S" are as defined by the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem. (1976) 45, 13-10. ET receptor antagonists having asymmetrically substituted carbon atoms with equal amounts of R and S configurations are racemic at those carbon atoms. Atoms with an excess of one configuration over the other are assigned the configuration in the higher amount, preferably an excess of about 85%-90%, more preferably an excess of about 95%-99%, and still more preferably an excess greater than about 99%. Accordingly, this invention is meant to embrace racemic mixtures, relative and absolute stereoisomers, and mixtures of relative and absolute stereoisomers of the ET receptor antagonists therein.
The term "relative stereochemistry," as used herein, refers to the direction of the variable R 1 and R 2 moieties in relation to the direction of the fixed carboxyl moiety to which each is adjacent. In a preferred embodiment, R 1 and R 2 are in the opposite direction of the carboxyl moiety and form the "trans,trans-" stereochemistry shown in the compound having formula (I)-b.
The term "absolute stereochemistry," as used herein, refers to the fixed direction of each fixed or variable moiety regardless of the orientation of the other substituents. The compounds having formula (I)-a and formula (I)-b may also contain carbon-carbon double bonds in the Z or E configuration, in which the term "Z" represents the larger two of the four substituents on same side of a carbon-carbon double bond and the term "E" represents the larger two of the four substituents on opposite sides of a carbon-carbon double bond. The compounds having formula (I)-a and formula (I)-b may also exist as an equilibrium mixture of Z and E configurations.
Compounds having formula (I)-a and formula (I)-b containing hydroxyl, amino, or carboxylic acids may have attached thereto prodrug-forming moieties. The prodrug-forming moieties are removed by metabolic processes and release the compounds having the freed hydroxyl, amino, or carboxylic acid in vivo. Prodrugs are useful for adjusting such pharmacokinetic properties of the compounds, or their metabolites, as solubility and/or hydrophobicity, absorption in the gastrointestinal tract, bioavailability, tissue penetration, and rate of clearance. Examples of prodrugs of the compounds include ones in which the carboxyl moiety of the compounds have attached thereto a methyl, ethyl, isopropyl, or tert-butyl moiety. The compounds having formula (I)-a and formula (I)-b may be prepared by synthetic processes or metabolic processes. Metabolic processes include those processes occurring in vitro or in vivo. An example of a metabolite of the compounds is one in which R 1 is 4-methoxyphenyl; R2 is l,3-benzodioxol-5-yl; and R 3 is ((N-butylamino)carbonyl)methyl. The compounds having formula (I)-a and formula (I)-b may exist as acid addition salts, basic addition salts, or zwitterions. Salts of the compounds are prepared during their isolation or following their purification. Acid addition salts of the compounds are those derived from the reaction of the same with an acid. For example, the acetate, adipate, alginate, citrate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, camphorate, camphorsufonate, digluconate, glycerophosphate, hemisulfate, heptanoate, hexanoate, formate, fumarate, hydrochloride, hydrobromide, hydroiodide, lactate, maleate, mesitylenesulfonate, methanesulfonate, naphthylenesulfonate, nicotinate, oxalate, pectinate, persulfate, picrate, propionate, succinate, tartrate, thiocyanate, trichloroacetic, trifluoroacetic, phosphate, glutamate, bicarbonate, para-toluenesulfonate, lactobionate, and undecanoate salts of the compounds and prodrugs thereof are contemplated as being within the scope of this invention. Because the compounds contain carboxylic acids, basic addition salts may be prepared therefrom by reaction with a base such as the hydroxide, carbonate, or bicarbonate of cations such as lithium, sodium, potassium, calcium, and magnesium. A preferred salt of the compounds is the hydrochloride salt.
The compounds having formula (I)-a and formula (I)-b may be administered with or without an excipient and with or without another chemotherapeutic agent. Excipients include encapsulating materials or formulation additives such as absorption accelerators, antioxidants, binders, buffers, coating agents, coloring agents, diluents, disintegrating agents, emulsifiers, extenders, fillers, flavoring agents, humectants, lubricants, perfumes, preservatives, propellants, releasing agents, sterilizing agents, sweeteners, solubilizers, wetting agents, and mixtures thereof.

DETERMINATION OF HEALTH-RELATED QUALITY-ADJUSTED TΓME-TO-DISEASE PROGRESSION
The health-related QATTP of disease model for this invention expresses progression-free time as an equally preferable amount of time spent in full health. This is achieved by using patient-reported health-related QoL, as measured for the duration of observation or progression-free interval, to weight progression-free time. These data were collected from randomized patients having hormone refractory prostate cancer (HRPCa) with the following validated instruments: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-30) and the Functional Assessment of Cancer Therapy (FACT-G) and its prostate cancer-specific module (FACT-P).
Patients received treatment with 10 mg (N=89) or 2.5 mg (N=95) of atrasentan or placebo (N=104) until experiencing a clinical event indicative of disease progression such as palliative opiate treatment of new bone or visceral pain, palliative radiation treatment of new bone pain, or new tumor growth symptoms requiring intervention or treatment with chemotherapy. Patient-reported health-related QoL data were collected with the EORTC QLQ-30 and the FACT-G and FACT-P, both of which were administered at baseline, at six week intervals and at each patient's final visit. The results from the 10 mg and 2.5 mg treatment groups are reported relative to the placebo group. A patient's transformed domain score and total score from both the
EORTC QLQ-30 and FACT were used to weight the time-to-progression outcome data. Transformed domain scores ranged between 0 and 1, so the reported health-related QATTP of disease outcome was never larger than the actual time-to-progression. The methods used for converting domain scores to weight adjustments are shown in TABLE 1.
TABLE 1
TRANSFORMATION OF HEALTH-RELATED QUALITY OF LIFE INSTRUMENT
DOMAIN SCORES TO WEIGHTED ADJUSTMENTS
A higher score means a better health-related QoL. A higher transformed score means improved health-related QoL.
A higher score means a worse health-related QoL. A higher transformed score means improved symptoms. Possible scores for the fourteen EORTC domains each range between 1 and 100.
For six domains (physical, emotional, role, social, and cognitive functioning and global score), a higher score means a better health-related QoL. These six scores were transformed to weights by dividing the patient-reported scores by 100.
For the remaining eight EORTC domains, a higher score indicates worse symptoms (a worse health-related QoL). These domains are pain, fatigue, nausea and vomiting, appetite loss, dysnepa, sleep disturbance, diarrhea, and constipation. These eight scores were converted to weight adjustments by dividing them by 100 and subtracting the result from the integer 1 to provide consistent directionality of response. FACT domain scores were converted to weights using the linear affine transformation suggested in SF-36 Health Survey Manual and Interpretation Guide.
Each patient's health-related QATTP of disease was computed as the sum of the health-related QoL weights multiplied by the duration for which that patient experienced that health-related QoL.
If a patient experienced a clinical event between two health-related QoL assessments, the set of health-related QoL domain scores immediately prior to the event were carried forward to the time of the clinical event. The mean and median health- related QATTP of disease outcomes were then estimated using Kaplan-Meier product limit methodology (Journal of the American Statistical Association, vol. 53, 1958, pp 457- 481). The area under a Kaplan-Meier survival curve conveys an estimated mean health- related QATTP of disease. This analysis was applied to both intent-to-treat and per protocol population data. All health-related QATTP of disease comparisons between atrasentan and placebo treatment groups were based on a log-rank test with statistical significance at an α of 0.05.
Results of the Kaplan-Meier product limit survival method analysis are reported in TABLE 2 (Intent to Treat) and TABLE 3 (Per Protocol Population). Mean and median health-related QATTP of disease are shown by treatment group. Log-rank tests comparing the differences between treatment groups are also reported. The Kaplan-Meier product limit method may provide biased results if study data are obtained under certain conditions such as staggered entry of subjects into the study and/or incomplete follow-up (Biometrics. 1989; 5:781-795). Thus, a second analysis was implemented to verify that the conclusions derived from the Kaplan-Meier method would remain robust to the length of follow-up. The assumption was that all patients were followed for one year. Patients who discontinued from the study prior to one year of observation had their last observation for all health-related QoL domains carried forward through the remainder of the year. Similarly, patients who had not completed one year of observation had their health-related QoL data carried forward through one year. If the patient experienced a clinical event within the one year period, the last observation was not carried forward. The Area under the Curve (AUC) value for each domain was computed by multiplying the health-related QoL domain score by the respective duration of that score. Finally, AUC values were aggregated across all subjects within each respective treatment group (atrasentan (10 mg), atrasentan (2.5 mg), and placebo). Aggregated AUC values for each domain were compared for differences between treatment groups using a t-test.

aP- Values from Kaplan-Meier log-rank test of differences in health-related QATTP of disease curves. * Significant at p<0.05. At. is atrasentan. PI. is placebo.
The data in TABLE 2 show significantly longer (p<0.05) mean health-related QATTP's of disease for all health-related QoL domains except dyspnea, global score, emotional well-being, and social well-being in the 10 mg atrasentan treatment group. In the dyspnea, global score, emotional well-being, and social well-being domains, the trend favored the 10 mg atrasentan treatment group (p<0.10). The 2.5 mg atrasentan treatment group also produced longer mean health-related QATTP of disease. Log rank tests showed these results to be statistically significant for all health-related QoL domains except dyspnea and functional well-being; and there were no statistical differences noted between the atrasentan treatment groups for any health-related QoL domain.
The data in TABLE 3 show both delays and improvement in the mean health-related QATTP's of disease in the both 10 mg and 2.5 mg atrasentan treatment groups.
The AUC analysis results were consistent with the health-related QATTP analyses in TABLES 2 and 3. For the Intent to Treat population (TABLE 2), atrasentan treatment and placebo groups showed no statistical differences. The AUC analysis of the per-protocol population showed strong trends in favor of the atrasentan treatment groups in every health-related QoL domain score when compared to placebo. The responses in the 10 mg and 2.5 mg treatment groups were not statistically differentiable. The AUC for the health-related QoL domain scores for physical functioning, social functioning, and pain were significantly longer (p<0.05) for atrasentan. Similarly, the 2.5 mg atrasentan group showed significantly improved AUC results except for dyspnea, social/family, functional well-being, and FACT-P domain scores.
The impact of the 10 mg and 2.5 mg atrasentan treatment on the patients' perceived health-related QoL was also addressed. Patient-reported health-related QoL data has validity for two reasons: the perception of health is stated by the patient directly, and multidimensional health-related QoL instruments provide a more complete and balanced assessment of patients' health status. It was found that after adjusting for health-related QoL effects, both 10 mg and 2.5 mg atrasentan therapies offered longer health-related QATTP over placebo in the per protocol population. These gains in the health-related QATTP were robust over a wide range of health-related QoL domain weighting and were consistently observed using the EORTC and FACT as the two health-related QoL instruments. For the intent-to-treat population, there were no statistically significant differences in the QATTP across treatment groups. This finding is consistent with the fact that, for the intent-to-treat population, no statistically significant differences were observed in either the time to disease or PSA progression across treatment groups.
Additional AUC analyses showed that after adjusting for possible bias induced by unequal lengths of follow-up and the staggered entry of subjects, the findings produced by the Kaplan-Meier methods were confirmed.
Thus, both the health-related QoL and the health-related QATTP of disease in patients with prostate cancer are favorably modulated by administration of an ET antagonist, preferably an ETA antagonist such as atrasentan.
