Belantamab mafodotin‑blmf is a B‑cell maturation antigen (BCMA)‑directed antibody and microtubule inhibitor conjugate. Belantamab mafodotin‑blmf is an antibody conjugate composed of 3 components: 1) afucosylated, humanized immunoglobulin G1 monoclonal antibody covalently linked to 2) the microtubule inhibitor mcMMAF via 3) a protease‑resistant maleimidocaproyl linker. The antibody is produced in a mammalian cell line (Chinese Hamster Ovary) using recombinant DNA technology and the microtubule inhibitor and linker are produced by chemical synthesis. Approximately 4 molecules of mafodotin are attached to each antibody molecule. The molecular weight of belantamab mafodotin‑blmf is approximately 152 kDa. Belantamab mafodotin‑blmf has the following structure: BLENREP (belantamab mafodotin‑blmf) for injection is a sterile, preservative‑free, white to yellow, lyophilized powder in a single‑dose vial for reconstitution and further dilution prior to intravenous use. BLENREP is supplied as 70 mg per vial and requires reconstitution with 1.4 mL of Sterile Water for Injection, USP, to obtain a concentration of 50 mg/mL. Each mL of reconstituted solution contains belantamab mafodotin‑blmf (50 mg) and the inactive ingredients, citric acid monohydrate (0.46 mg), edetate disodium (0.017 mg), polysorbate 80 (0.2 mg), sodium citrate (5.88 mg), and trehalose (68.4 mg). The pH of the reconstituted solution is 6.2. Belantamab mafodotin-blmf chemical structure
