Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To evaluate the preliminary efficacy of in reducing the frequency and severity of vasomotor symptoms (VMS) in men on androgen deprivation therapy (ADT).	Efficacy will be assessed using a composite outcome of median weekly hot flash frequency and severity at week 4 compared to baseline.	28 days
Secondary	To evaluate the effect of Osanetant on follicle stimulating hormone for men with prostate cancer on ADT.	Levels of follicle stimulating hormone (FSH) will be measured at week 4 will be compared to baseline.	28 days
Secondary	To evaluate the effect of Osanetant on luteinizing hormone for men with prostate cancer on ADT.	luteinizing hormone (LH) will be measured at week 4 will be compared to baseline.	28 days
Secondary	To evaluate the effect of Osanetant on testosterone for men with prostate cancer on ADT.	testosterone will be measured at week 4 will be compared to baseline.	28 days
Secondary	To evaluate the effect of Osanetant on estradiol for men with prostate cancer on ADT.	estradiol will be measured at week 4 will be compared to baseline. with prostate cancer on ADT	28 days
Secondary	Functional Assessment of Cancer Therapy-Prostate (FACT-P)	To evaluate the impact of Osanetant on global quality of life with Functional Assessment of Cancer Therapy-Prostate (FACT-P)	28 days
Secondary	EuroQOL 5-dimension	To evaluate the impact of Osanetant on global quality of life with a visual analog scale from EuroQOL 5-dimension, 5-level (EQ-5D-5L). The EQ-5D-5L visual analog scale is 0-100 with higher numbers being better.	28 days
Secondary	Patient Health Questionnaire-9 question (PHQ-9).	To evaluate the impact of Osanetant on depressive symptoms on Patient Health Questionnaire-9 question (PHQ-9).	28 days
Secondary	General Anxiety Disorder-7 question (GAD-7)	To evaluate the impact of Osanetant on anxiety symptoms on General Anxiety Disorder-7 question (GAD-7).	28 days
Secondary	Hot Flash Related Daily Interference Scale (HFRDIS).	To evaluate the impact of Osanetant on hot flash interference using the Hot Flash Related Daily Interference Scale (HFRDIS). The hot flash daily interference scale has a minimum of 0 and a max of 100, with higher scores indicating more interference (which is worse).	28 days
