boxed warning
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. In the clinical study, 83% of patients required a dosage modification due to ocular toxicity. Withhold BLENREP until improvement and resume or permanently discontinue, based on severity [see Dosage and Administration ( 2.3 ), Warnings and Precautions ( 5.1 )] . • Because of the risk of ocular toxicity, BLENREP is available only through a restricted program called the BLENREP Risk Evaluation and Mitigation Strategy (REMS) [see Warnings and Precautions ( 5.2 )] .

warnings and cautions
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. The most common ocular toxicities (>25%) were reduction in BCVA (89%) and corneal exam findings (86%) based on ophthalmic exam findings, blurred vision (66%), dry eye (51%), photophobia (47%), foreign body sensation in eyes (44%), eye irritation (43%), and eye pain (33%) [see Adverse Reactions ( 6.1 )] . Ocular toxicity based on ophthalmic exam findings was reported as Grade 2 in 9% of patients, Grade 3 in 56% of patients, and Grade 4 in 21% of patients. The median time to onset of the first Grade 2 to 4 ophthalmic exam findings was 43 days (range: 15 to 611 days). The median duration of all Grade 2 to 4 ophthalmic exam findings was 85 days (range: 5 to 813 days). Patients experienced a median of 3 episodes (range: 1 to 11 episodes) of ocular toxicity based on ophthalmic exam findings. Of the patients with Grade 2 to 4 ophthalmic exam findings, 42% had improvement of the last event to Grade 1 or better; 22% had resolution of the last event based on return to baseline or normal ophthalmic exam findings. The most commonly reported corneal exam findings included superficial punctate keratopathy, microcyst-like deposits, epithelial changes, and haze. Cases of corneal ulcer, including cases with infection, have been reported and should be managed promptly by an eye care professional [see Adverse Reactions ( 6.1 )] . A reduction in BCVA to 20/50 or worse in at least one eye occurred in 69% of patients, including 29% who experienced a change in BCVA to 20/100 or worse, and 12% who experienced a change in BCVA to 20/200 or worse. Of the patients with reduced BCVA to 20/50 or worse in at least one eye, 61% had resolution of the last event to baseline or better. Of the patients ...

adverse reactions
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. The most common Grade 3 or 4 (≥10%) laboratory abnormalities are decreased platelets, decreased lymphocytes, decreased neutrophils, increased gamma-glutamyl transferase, decreased white blood cells, and decreased hemoglobin. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact GlaxoSmithKline at 1-888-825-5249 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Relapsed or Refractory Multiple Myeloma in Combination with Bortezomib and Dexamethasone The safety of BLENREP with bortezomib and dexamethasone (n = 242) compared with daratumumab with bortezomib and dexamethasone (n = 246) was evaluated in DREAMM‑7 in patients with relapsed or refractory multiple myeloma who received at least one prior line of therapy [see Clinical Studies ( 14 )] . Patients received BLENREP 2.5 mg/kg of actual body weight once every 3 weeks in combination with bortezomib and dexamethasone (BVd) for the first 8 cycles, followed by BLENREP as a single agent or daratumumab in combination with bortezomib and dexamethasone (DVd) for the first 8 cycles, followed by daratumumab as a single agent. Among patients who received BLENREP, 69% were exposed for 6 months or longer and 55% were exposed for greater than one year. The safety of BLENREP in combination with bortezomib and dexamethasone in patients who received only one prior line of therapy (n = 125) has not been established. Serious adverse reactions occurred in 50% of patients who received BVd. Serious adverse reactions in ≥2% of patients...
