Overview

Ifinatamab deruxtecan + pembrolizumab is an investigational combination therapy currently in clinical development for the treatment of advanced cancers, primarily esophageal squamous cell carcinoma and non-small cell lung cancer. **Ifinatamab deruxtecan** (I-DXd, DS-7300a, MK-2400) is an antibody-drug conjugate (ADC) targeting B7-H3 (CD276) on tumor cells; it delivers a topoisomerase I inhibitor payload via a cleavable linker, leading to targeted cytotoxicity. **Pembrolizumab** (Keytruda, MK-3475) is a monoclonal antibody that blocks the interaction between PD-1 and its ligands (PD-L1/PD-L2), enhancing T-cell mediated immune responses against tumors. The combination aims to exploit both **direct tumor cell kill by ADC** and **enhanced immune checkpoint inhibition**, with early-phase trials underway to evaluate safety and efficacy in multiple cancer indications[1][4][7][10].
