Clinical Trial Summary

The overall aim of the trial is to investigate the safety and anti-tumour activity of an experimental drug BI 836845 taken together with the prostate cancer drug, enzalutamide, compared to enzalutamide given alone, in castrate resistant prostate cancer (CRPC) patients that have previously been treated and failed on docetaxel and abiraterone treatments. Initially, a tolerability and safety phase (phase Ib escalation) will be performed to confirm the maximum tolerated dose (MTD), or recommended doses of both BI 836845 and enzalutamide that can be taken together. Once the MTD, or recommended phase II dose, have been determined an expansion cohort will also be explored (phase Ib expansion) in CRPC patients already taking enzalutamide and have a rise in prostate serum antigen (PSA) levels. Patients may not have received prior docetaxel or abiraterone. Patients in this cohort will receive the MTD, or recommended phase II dose, of BI 836845 and enzalutamide determined in the phase Ib escalation phase. The randomised trial (phase II) will be an open label, parallel group study design in a 1:1 ratio to which patients will receive either BI 836845 plus enzalutamide (Arm A) at the MTD/recommended doses, or enzalutamide alone (Arm B). In all parts of the trial safety, anti-tumour activity will be assessed, in addition to circulating tumour cells (CTC), prostate serum antigen (PSA) response and progression, and determination of Overall Survival (OS).

The QTcF will be calculated as the mean of the 3 ECGs taken at screening. - Patients with small cell or neuroendocrine tumours. - Patients with known or suspected leptomeningeal metastases. - Uncontrolled or poorly controlled hypertension. - Known human immunodeficiency virus infection or acquired immunodeficiency syndrome-related illness. - Patients with epilepsy, seizures, or predisposing factors for seizure as judged by the investigator. - Patients unable to comply with the protocol as judged by the investigator. - Active alcohol or active drug abuse as judged by the investigator. - A history of allergy to human monoclonal antibodies. - Patients who are sexually active and unwilling to use a medically acceptable method of contraception, e.g. condom plus spermicide use for participating males, plus another form of birth control such as implants, injectables, combined oral contraceptives, intrauterine devices for female partners, during the trial and for at least three months after end of active therapy. Men unwilling to agree to not donate sperm while on trial drug and up to 6 months following the last dose of trial drug. - Previous or concomitant malignancies at any other site with the exception of the following: - benign basal cell carcinoma - benign low grade transitional cell carcinoma of the bladder - other effectively treated malignancy that has been in remission for more than 5 years and is considered to be cured - Only for patients entering phase Ib dose escalation and phase II cohorts: - Patients who have received more than 2 prior non-docetaxel containing cytotoxic chemotherapy regimens for Metastatic Castration-Resistant Prostate Cancer (mCRPC). - Patients who have received a taxane based treatment or abiraterone, within 4 weeks before start of study treatment. - Patients that have received prior enzalutamide in any setting will not be eligible. Exclusion criterion only for patients entering phase Ib expansion cohort: - Patients that have received prior taxane-based chemotherapy or abiraterone in any setting will not be eligible for the expansion cohort. Additional exclusion criterion for patients undergoing tumour biopsy: - For patients that are to undergo the tumour biopsy, a history of a hereditary bleeding disorder, or clinically relevant major bleeding event in the past 6 months, as judged by the investigator. - Further exclusion criteria apply
