Study Details

Study Description

Brief 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.

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed 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.

Drug: Enzalutamide
Androgern receptor inhibitor

Outcome Measures

Primary Outcome Measures

  1. Patient Preference Questionnaire [Week 29 (at the end of second treatment)]

    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.

Secondary Outcome Measures

  1. The side effect profile as assessed Patient Preference Questionnaire [Baseline to week 29 (the end of the study)]

    In Patient Preference Questionnaire, participants completed a sideffect checklist.

  2. Physician Preference Questionnaire [Week 29 (at the end of second treatment)]

    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.

  3. Caregiver Preference Questionnaire [Week 29 (at the end of second treatment)]

    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.

  4. The Functional Assessment of Cancer Therapy-Prostate Questionnaire (FACT-P) [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).]

    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

  5. Quality of life measured by EurolQol instrument (EQ-5D-5L) [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]

    This questionnaire consists of two parts, namely the EQ-5D-5L Descriptive System and the EQ Visual Analog Scale, the higher the score the better in quality of life

  6. FACT-Cognitive Function Version 3 (FACT-Cog) [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]

    This is a well-established 37-item questionnaire assessing patients' perceived cognitive impairments, perceived cognitive abilities, noticeability or comments from others, and impact of cognitive changes on quality of life. The higher the score, the better the QOL.

  7. Brief Fatigue Inventory (BFI) [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]

    This is a well-established 9-item questionnaire assessing patients' degree of fatigue.The higher the score, the higher fatigue level
