A Clinical Study of Ifinatamab Deruxtecan (I-DXd) in People With Metastatic Prostate Cancer (MK-2400-001)
Purpose
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 Criteria
The main exclusion criteria include but are not limited to the following: - Is unable to swallow tablets/capsules - Has any of the following indicators of interstitial lung disease (ILD)/pneumonitis: 1. Has any history of ILD/pneumonitis that required steroid use, except for a history of radiation pneumonitis that did not require steroids 2. Has current ILD/pneumonitis 3. 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 - 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 a "superscan" bone scan
