En fase III-undersøgelse af BNT324 versus docetaxel ved metastatisk kastrationsresistent prostatakræft

15. oktober 2026 opdateret af: BioNTech SE

En fase III, randomiseret, åben-label undersøgelse af BNT324 versus docetaxel med prednison/prednisolon ved metastatisk kastrationsresistent prostatakræft

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]).

Detaljeret beskrivelse

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.
