Overview

This is a **combination therapy** composed of ifinatamab deruxtecan, an antibody-drug conjugate (ADC) targeting B7-H3 with a topoisomerase I inhibitor cytotoxic payload, and enzalutamide, a second-generation nonsteroidal antiandrogen that acts as a potent antagonist of the androgen receptor. Ifinatamab deruxtecan binds specifically to B7-H3, a cell surface antigen overexpressed in various solid tumors, leading to intracellular delivery of deruxtecan, which induces DNA damage and apoptosis in tumor cells[1][3][5]. Enzalutamide inhibits androgen receptor signaling, blocking the effects of androgens and arresting growth of androgen-driven prostate cancer cells[2][4][6]. This combination is being studied for the treatment of cancer, with strong evidence for use in small cell lung cancer (SCLC) and prostate cancer.
