Phase 3 Study Comparing Pasritamig With Docetaxel Versus Docetaxel Alone in Men With Metastatic Castration-Resistant Prostate Cancer

What this Trial Is About

Researchers are evaluating whether combining pasritamig with docetaxel can extend the time before prostate cancer worsens in men with metastatic castration-resistant prostate cancer mCRPC, a type of prostate cancer that continues to grow despite low hormone levels. This Phase 3 study compares pasritamig plus docetaxel against docetaxel alone to see if the combination improves radiographic progression-free survival rPFS, which is the time until disease progression or death as seen on scans. Participants are randomly assigned to receive either pasritamig together with docetaxel or docetaxel plus prednisoneprednisolone as background medication. Treatment continues until disease progression is confirmed by scans or other criteria are met. The study is open-label, meaning both participants and researchers know which treatment is given. During the trial, participants will have regular scans such as CT, MRI, or bone scans to monitor disease progression, assessed by independent review. Researchers will also evaluate overall survival, symptom progression, response rates, prostate-specific antigen PSA levels, quality of life measures, and safety by tracking adverse events and lab results. The study may last up to approximately 4 years and 5 months, with frequent assessments throughout.
