Time frame
Predose, end of infusion (EOI), and 2 hours postdose on Cycle 1 Day 1, anytime sample at Cycle 1 Day 4, 8, 29; Predose and EOI on Day 1 of Cycle 2, 4, 6, 9, 12; Predose on Cycle 18 Day 1; and at end of treatment (~137 weeks)
What was measured
Blood samples were collected for PK analysis of belantamab mafodotin Antibody-Drug Conjugate (ADC).
Analysis population: Pharmacokinetic (PK) population included all participants in the safety population from whom at least one PK sample has been obtained and analyzed. Only those participants who were measured and analyzed (i.e., contributed data reported in the table) were included in the Overall Number of Participants Analyzed field. 'Number Analyzed' signifies participants evaluable for the specified timepoints.
Participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 0.5 mg/kg belantamab mafodotin intravenous (IV) infusion as powder for solution once every 4 weeks (Q4W) infused over 30- 60 minutes on day 1 of each 28-day cycle in combination with 100 mg Nirogacestat administered orally twice a day (BID) up to Day 28. Along with 4 mg Pomalidomide orally per day (QD) on Days 1-21 of each 28-day cycle and Dexamethasone 40mg (20 mg for participants \>75 years old or BMI \<18.5 kg/m\^2) administered orally on days 1, 8, 15 and 22 of each 28-day cycle.
