BLENREP (belantamab mafodotin-blmf)
BLENREP (belantamab mafodotin-blmf) is an antibody-drug conjugate indicated for use in combination with bortezomib and dexamethasone to treat adult patients with relapsed or refractory multiple myeloma. This therapeutic regimen is intended for patients who have already received at least two prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent. By targeting specific proteins on cancer cells, the drug provides a specialized treatment option for advanced stages of the disease.
How BLENREP Works
Belantamab mafodotin-blmf is an antibody-drug conjugate that targets the B-cell maturation antigen (BCMA) found on multiple myeloma cells. After binding to BCMA, the drug is internalized and releases a cytotoxic microtubule inhibitor that disrupts the cell's internal structure, leading to cell cycle arrest and apoptosis. The drug also facilitates tumor cell destruction through immune-mediated mechanisms, specifically antibody-dependent cellular cytotoxicity and phagocytosis.

BLENREP Target & Pathway
ProTarget
A protein highly expressed on malignant plasma cells in multiple myeloma. BCMA-targeted therapies, including CAR-T cells and bispecific antibodies, can eliminate myeloma cells while sparing most normal immune cells.
BLENREP Competitive Set
ProThree rings of competition based on shared molecular targets and treated indications.
Direct competitors
Same target(s) AND same indication — head-to-head.

Filters applied: drops same-active-ingredient (505(b)(2) reformulations), route-mismatch (topical vs systemic), and cross-therapeutic-area matches in same-indication rings.
