- Original description
Researchers are looking for new ways to treat metastatic castration-resistant prostate cancer (mCRPC). Researchers have designed a study medicine called ifinatamab deruxtecan (also called I-DXd or MK-2400) to treat mCRPC. The goal of this study is to learn if people who receive I-DXd live longer overall and live longer without the cancer growing or spreading than people who receive chemotherapy.Read full original descriptionShow less
A Phase 3, Open-label Study of Ifinatamab Deruxtecan Versus Docetaxel in Participants With Metastatic Castration-Resistant Prostate Cancer (mCRPC) (IDeate-Prostate01)
Researchers are looking for new ways to treat metastatic castration-resistant prostate cancer (mCRPC). Researchers have designed a study medicine called ifinatamab deruxtecan (also called I-DXd or MK-2400) to treat mCRPC. The goal of this study is to learn if people who receive I-DXd live longer overall and live longer without the cancer growing or spreading than people who receive chemotherapy.

Exclusion: Has received prior treatment with a taxane-based chemotherapy agent for metastatic castration-resistant prostate cancer (mCRPC); Has had prior discontinuation of an antibody drug conjugate (ADC) that consists of an exatecan derivative (eg, trastuzumab deruxtecan) due to treatment-related toxicities; Has any of the following indicators of interstitial lung disease (ILD)/pneumonitis:; Has any history of ILD/pneumonitis that required steroid use, except for a history of radiation pneumonitis that did not require steroids; Has current ILD/pneumonitis; Has a clinical or radiographic suspicion of ILD for which the diagnosis of ILD cannot be ruled out; Has clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses; Has uncontrolled or significant cardiovascular disease; The main exclusion criteria include but are not limited to the following:; Is unable to swallow tablets/capsules; Has a "superscan" bone scan.
