En fas III-studie av BNT324 jämfört med docetaxel vid metastaserad kastrationsresistent prostatacancer
En fas III, randomiserad, öppen prövning av BNT324 jämfört med docetaxel tillsammans med prednison/prednisolon vid metastaserad kastrationsresistent prostatacancer
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]).

Detaljerad beskrivning
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, i.e., BNT324 group, or docetaxel plus prednisone/prednisolone group (current SoC). An independent committee will help ensure participant safety, by regularly reviewing safety and early results.
For each participant, the treatment and follow-up periods are projected to be up to ~58 months.
