What was measured

Blood samples were collected for PK analysis of belantamab mafodotin Total Antibody. As pre-specified in protocol, only specified treatment arms were planned to be analyzed for this outcome measure. As first dose of belantamab mafodotin was administered on Day 1, cycle length correlates to Day 1 plus 21 days i.e., Day 22 in timeframe. For some participants, dosing in Cycle 2 or Cycle 4 was delayed, resulting in the pre-dose samples in these cycles (C2D1 or C4D1) being collected later than the protocol-defined planned days after dosing in C1D1 or C3D1. Consequently, the last PK samples for these participants were collected outside the pre-defined protocol time points, and certain Tlast values in the data table extend beyond the original protocol-defined Time Frame.

Analysis population: Pharmacokinetic Evaluable population. 'Cycle 1' and 'Cycle 3' include the full first and third cycles, along with the Day 1 of Cycle 2 (C2D1) and Cycle 4 (C4D1) Predose periods, respectively. Only those participants who were measured and analyzed (i.e., contributed to data reported in the table) were included in the Overall Number of Participants Analyzed field. 'Number Analyzed' signifies participants evaluable for the specified timepoints.

Groups in this outcome

Part 1: Belantamab Mafodotin 2.5 mg/kg (Normal/Mildly Impaired Renal Function)

Participants with Relapsed/Refractory Multiple Myeloma (RRMM) who have had at least 3 lines of prior treatment (or at least 2 lines of prior treatment if ineligible for autologous stem cell transplantation) and normal/mildly impaired renal function received intravenous (IV) infusion of 2.5 milligram (mg)/kilogram (kg) belantamab mafodotin for 30 minutes on Day 1 of every 21-day Cycle until disease progression, withdrawal of consent, withdrawal due to adverse event (AE), lost to follow-up, death, whichever occurs first.

Part 1: Belantamab Mafodotin 2.5 mg/kg (Severely Impaired Renal Function)

Participants with RRMM who have had at least 3 lines of prior treatment (or at least 2 lines of prior treatment if ineligible for autologous stem cell transplantation) and severe renal impairment renal function received IV infusion of 2.5 mg/kg belantamab mafodotin for 30 minutes on Day 1 of every 21-day Cycle until disease progression, withdrawal of consent, withdrawal due to AE, lost to follow-up, death, whichever occurs first.
