A Study of Risvutatug Rezetecan in Participants With Metastatic Castration-resistant Prostate Cancer (mCRPC) [EMBOLD Prostate-302]
A Phase 3 Randomized Study to Evaluate the Safety and Efficacy of Risvutatug Rezetecan, a B7-H3 Antibody Drug Conjugate (ADC) in Participants With Metastatic Castration-resistant Prostate Cancer (EMBOLD Prostate-302)
This study aims to evaluate how well risvutatug rezetecan (Ris-Rez) works in treating prostate cancer compared to best supportive/standard of care (BSC) which may include a hormone therapy with an androgen receptor pathway inhibitors (ARPI), by checking whether it makes cancers smaller or disappear completely, if it helps participants live longer, and/or feel better. The study is also assessing whether Ris-Rez is safe and tolerated well by participants and aims to provide a better understanding of the side effects of the drug.
