Belantamab Mafodotin

1 INDICATIONS AND USAGE BLENREP is indicated in combination with bortezomib and dexamethasone for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least two prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent. BLENREP, a B‑cell maturation antigen (BCMA)‑directed antibody and microtubule inhibitor conjugate, is indicated in combination with bortezomib and dexamethasone for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least two prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Ocular Toxicity [see Warnings and Precautions ( 5.1 )] • Thrombocytopenia [see Warnings and Precautions ( 5.3 )] The most common adverse reactions (≥20%) with BLENREP in combination with bortezomib and dexamethasone are reduction in best-corrected visual acuity (BCVA), corneal exam findings, blurred vision, dry eye, photophobia, foreign body sensation in eyes, eye irritation, upper respiratory tract infection, hepatotoxicity, eye pain, diarrhea, fatigue, pneumonia, cataract, and COVID-19.

8.1 Pregnancy Risk Summary Based on its mechanism of action, BLENREP can cause fetal harm when administered to a pregnant woman, because it contains a genotoxic compound (the microtubule inhibitor, MMAF) and it targets actively dividing cells [see Clinical Pharmacology ( 12.1 ), Nonclinical Toxicology ( 13.1 )] . Human immunoglobulin G (IgG) is known to cross the placenta; therefore, belantamab mafodotin-blmf has the potential to be transmitted from the mother to the developing fetus. There are no available data on the use of BLENREP in pregnant women to evaluate for drug-associated risk.

WARNING: OCULAR TOXICITY • BLENREP causes changes in the corneal epithelium resulting in changes in vision, including severe visual impairment, and symptoms such as blurred vision and dry eyes. In the clinical study, corneal ulcers, including cases with infection, also occurred [see Warnings and Precautions ( 5.1 )] . • Conduct ophthalmic exams at baseline, before each dose, promptly for new or worsening symptoms, and as clinically indicated. 5 WARNINGS AND PRECAUTIONS • Thrombocytopenia: Monitor complete blood counts at baseline and periodically during treatment. Withhold or reduce the dosage based on severity. ( 2.3 , 5.3 ) • Embryo‑fetal Toxicity: Can cause fetal harm. Advise patients of the potential risk to fetus and to use effective contraception. ( 5.4 , 8.1 , 8.3 ) 5.1 Ocular Toxicity BLENREP causes ocular toxicity, defined as changes in the corneal epithelium and changes in BCVA based on ophthalmic exam (including slit lamp exam), or other ocular adverse reactions as defined by the CTCAE [see Adverse Reactions ( 6.1 )] . In DREAMM-7, ocular toxicity occurred in 92% of patients, including Grade 3 or 4 in 77% of patients. 4 CONTRAINDICATIONS None. None. ( 4 )
