Clinical Trial Summary

This is a prospective, open-label, randomized, controlled, cross-over trial assessing patient preference for apalutamide versus enzalutamide in 146 male patients with recurrent or metastatic hormone-sensitive prostate cancer. The primary objective is to investigate whether there is any difference in patient preference between apalutamide and enzalutamide in patients with recurrent or metastatic hormone-sensitive prostate cancer.

Description:

This is a prospective, open-label, randomized, controlled, cross-over trial assessing patient preference for apalutamide versus enzalutamide in 146 male patients with recurrent or metastatic hormone-sensitive prostate cancer The primary outcome is patient preference, which serves as an indicator covering different aspects of treatment-related effects, and this would be most important in a patient's perspective. The quality of life, psychological and cognitive changes following apalutamide and enzalutamide in a comprehensive manner will be investigated.

Patient will receive two 12-weeks treatment periods with a 5-week wash-out period between the treatment periods. Patients will receive Apalutamide and Enzulutamide sequentially. Patient, physician and caregiver preferences will be assessed at the end of the second treatment period. Other secondary outcomes on health-related quality of life measures, psychological assessment scores and cognitive assessment scores shall be assessed before and the end of first treatment and second treatment period.

6. Prior use of chemotherapy, immunotherapy, radiopharmaceutical agents, CYP17 inhibitors (e.g. abiraterone acetate), enzalutamide or apalutamide for the treatment of prostate cancer or prior participation in a clinical trial of an investigational agent that inhibits the androgen receptor or androgen synthesis

Congestive heart failure New York Heart Association class 3 or 4, or a history of congestive heart failure New York Heart Association class 3 or 4, unless a screening echocardiogram or multigated acquisition scan performed within 3 months before randomization demonstrates a left ventricular ejection fraction = 50%;

Type	Measure	Description	Time frame	Safety issue
Primary	Patient Preference Questionnaire	This Patient Preference Questionnaire consists of 4 questions, assessing the patients preference on Apalutamide verse Enzalutamide, the factors that had an influence on their treatment preference, the most important reason for their preference and the side effect of first treatment and second treatment.	Week 29 (at the end of second treatment)
Secondary	The side effect profile as assessed Patient Preference Questionnaire	In Patient Preference Questionnaire, participants completed a sideffect checklist.	Baseline to week 29 (the end of the study)
Secondary	Physician Preference Questionnaire	This Physician Preference Questionnaire consists of 3 questions, assessing the physicians preference on Apalutamide verse Enzalutamide, the factors that had an influence on their treatment preference, the most important reason for their preference.	Week 29 (at the end of second treatment)
Secondary	Caregiver Preference Questionnaire	This Caregiver Preference Questionnaire consists of 3 questions, assessing the caregivers preference on Apalutamide verse Enzalutamide, the factors that had an influence on their treatment preference, the most important reason for their preference.	Week 29 (at the end of second treatment)
Secondary	The Functional Assessment of Cancer Therapy-Prostate Questionnaire (FACT-P)	This is a 39-item questionnaire assessing five domains including Physical Well-Being, Social and Family Well-Being, Emotional Well-Being, Functional Well-Being and Prostate Cancer Subscale.The higher the score, the better the QOL	Week 0 (before start of first treatment period), Week 12 (end of first treatment period), week 17 (before start of second treatment period) and Week 29 (end of second treatment period).
