New hope for tough prostate cancer: BNT324 takes on chemo
NCT ID NCT07365995
First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 5 times
Summary
This study tests a new drug called BNT324 against standard chemotherapy (docetaxel) in men with metastatic castration-resistant prostate cancer that has progressed after hormone therapy. The goal is to see if BNT324 helps patients live longer without their cancer worsening. About 736 men will participate in this Phase 3 trial.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BNT324 (also called DB-1311)
- What this could lead to
- If it works, BNT324 could offer a more effective treatment option for men with advanced prostate cancer that has stopped responding to hormone therapy.
- What could go wrong
- This is an early-stage Phase 3 trial, so results are not guaranteed. The new drug may not work better than current chemotherapy and could have unexpected side effects.

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 progression of bone disease: evaluable disease or new bone lesion(s) by bone scan per PCWG3 criteria. * Had previously received one or two prior androgen receptor pathway inhibitor treatments and experienced disease progression during or after a minimum of 8 weeks of therapy. * Must not have received systemic cytotoxic chemotherapy, including taxane-based chemotherapy, for mCRPC. * Must have had prior orchiectomy and/or have ongoing androgen-deprivation therapy and a castrate-level of serum/plasma testosterone (\<50 ng/dL or \<1.7 nmol/L). Participant being treated with luteinizing hormone-releasing hormone agonists or antagonists must continue such treatment throughout the study. * Must have an Eastern Cooperative Oncology Group performance score of 0 or 1. Key Exclusion Criteria: * Have received prior treatment with B7-H3 targeted therapy, including B7-H3 ADCs. * Have uncontrolled or significant cardiovascular disease, as defined in the protocol. * Have a history of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required steroids or have current ILD/pneumonitis. NOTE: Other protocol defined Inclusion/Exclusion criteria apply.
