The laboratory parameters were graded according to CTCAE v5.0. Grade 1 (G1): mild; Grade 2 (G2): moderate; Grade 3 (G3): severe; Grade 4 (G4) life-threatening or disabling. Higher grade indicates greater severity and an increase in CTCAE grade was defined relative to the Baseline grade. Any worst-case post baseline increases to G1, G2, G3, and G4 are presented. Baseline value was defined as the most recent, non-missing value from a local laboratory prior to the first dose of study treatment.","groups":[{"description":"In DE Phase, participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 0.95 milligram (mg)/kilogram (kg) belantamab mafodotin intravenous (IV) infusion as powder for solution once every 3 weeks (Q3W) infused over 30- 60 minutes on day 1 of 21-day cycles in combination with 100 mg nirogacestat administered twice a day (BID) on day 1, 4, 8 and 15 of 21-day cycles.
