A Phase III, Randomized, Open-label Trial of BNT324 Versus Docetaxel With Prednisone/Prednisolone in Metastatic Castration-resistant Prostate Cancer

BioNTech SE

Summary

This study will test whether BNT324 is safe and works better against metastatic castration-resistant prostate cancer (mCRPC) than the current standard of care (SoC) chemotherapy, which is docetaxel (given together with the steroid medicines prednisone or prednisolone). The study will include participants with mCRPC that have been previously treated with androgen receptor pathway inhibitor, but with no previous taxane-based systematic chemotherapy for mCRPC. The main goals of this study are: * To find out if BNT324 helps participants live longer without their cancer getting worse (radiographic progression-free survival \[rPFS\]). * To find out if BNT324 helps participants live longer overall (overall survival \[OS\]).

Description

The study consists of a screening period (up to 28 days), a treatment period with 21-day cycles, and an after-treatment period that includes a 30-day safety follow-up period and a long-term survival follow-up period. Treatment continues until the cancer clearly gets worse (in scans, based on blinded independent central review \[BICR\] assessment or investigator's decision), side effects become unacceptable, the participant chooses to stop, or the study ends. Participants are put into one of two groups in a 1:1 ratio, which means they will have an equal chance to be in either treatment group,…

Detailed criteria

Key Inclusion Criteria: * Are male adults (defined as ≥18 years of age or of an acceptable age according to local regulations at the time of giving informed consent). * Must have documented progressive prostate cancer based on at least one of the following criteria: * Serum/plasma PSA progression, by local laboratory, defined as two consecutive increases in PSA over a previous reference value, each measured sequentially at least 1 week apart. The PSA value at screening is required to be ≥1.0 ng/mL. * Radiographic soft tissue progression as per PCWG3-modified RECIST v1.1. * Radiographic…
