A Pilot Study of Neoadjuvant Non-fucosylated Anti-CTLA-4 (BMS-986218) + Degarelix Acetate vs. Degarelix Acetate Alone in Men With High-risk Localized Prostate Cancer
A Pilot Study of Neoadjuvant Non-fucosylated Anti-CTLA-4 (BMS-986218) + Degarelix Acetate vs. Degarelix Acetate Alone in Men With High-risk Localized Prostate Cancer
The purpose of this study is to see whether immunotherapy with BMS-986218 added to degarelix (which suppresses testosterone) given prior to surgery can decrease the chance that cancer will come back compared to degarelix alone. People who usually have this type of prostate cancer usually do not receive any additional therapy prior to surgery. Approximately 24 individuals will be asked to participate in this study.
This is a single-center, randomized, two-arm, study evaluating the safety, feasibility and immunogenicity of neoadjuvant degarelix(Arm A) or BMS-986218 plus degarelix (Arm B) prior to radical prostatectomy in men with high-risk localized prostate cancer (neo-RED-P). Our primary objective is to characterize safety, tolerability, and feasibility of degarelix with or without BMS-986218 in the neoadjuvant setting. The trial will monitor toxicity and safety, as well as surgery related adverse events. The secondary objectives will be to evaluate an immune response consistent with the proposed mechanism of action of BMS-986218, depletion of Tregs, and to assess the pathologic complete response rate, PSA response rate and time-to-PSA recurrence following treatment.
