Overview

Bintrafusp alfa + docetaxel is a **combination therapy** consisting of bintrafusp alfa, a bifunctional fusion protein targeting both programmed death-ligand 1 (PD-L1) and transforming growth factor-beta (TGF-β), and docetaxel, a cytotoxic taxane chemotherapeutic agent. Bintrafusp alfa acts by simultaneously blocking PD-L1-mediated immune evasion and trapping/sequestering TGF-β in the tumor microenvironment, thus reversing immunosuppression, enhancing T cell and NK cell antitumor activity, and inhibiting epithelial-mesenchymal transition (EMT) and chemotherapy resistance[2][4][7]. Docetaxel promotes microtubule stabilization and thereby inhibits mitosis, resulting in cancer cell death. This combination is being evaluated in clinical trials for several advanced solid tumors, including metastatic prostate cancer and non-small cell lung cancer (NSCLC), aiming to increase progression-free survival and response rates over chemotherapy or immunotherapy alone[1][3][7].
