En studie av Belantamab Mafodotin Monoterapi hos deltagare med multipelt myelom med normal och varierande grad av nedsatt njurfunktion (DREAMM12)

5 juni 2026 uppdaterad av: GlaxoSmithKline

En fas I-studie för att utvärdera farmakokinetiken och säkerheten för Belantamab Mafodotin Monoterapi hos deltagare med återfall och/eller refraktärt multipelt myelom (RRMM) som har normala och varierande grader av nedsatt njurfunktion (DREAMM 12)

Belantamab mafodotin är ett antikroppsläkemedelskonjugat (ADC) som innehåller humaniserad anti-B-cellmognadsantigen (BCMA) monoklonal antikropp (mAb). Nedsatt njurfunktion är en stor komplikation av multipelt myelom (MM) och majoriteten av MM-deltagare är antingen i riskzonen eller har redan nedsatt njurfunktion vid initial diagnos. Syftet med denna studie är att bedöma farmakokinetiken (PK), säkerheten och tolerabiliteten för monoterapi med belantamab mafodotin hos deltagare med RRMM, som har haft minst 3 rader tidigare behandling (eller minst 2 rader tidigare behandling om de inte är kvalificerade för autolog stamcellstransplantation) och har antingen normal eller nedsatt njurfunktion. Studien kommer att bestå av två delar: del 1 kommer att inkludera deltagare med normal/lindrigt nedsatt njurfunktion och gravt nedsatt njurfunktion och del 2 kommer att omfatta deltagare med njursjukdom i slutstadiet (ESRD), där deltagarna antingen inte genomgår eller behöver hemodialys. Deltagarna kommer att administreras belantamab mafodotin i en dos på 2,5 milligram per kilogram (mg/kg) intravenöst en gång i tre veckor (Q3W) i del 1. Baserat på del 1 säkerhet/farmakokinetiska (PK) data, kommer del 2 deltagare att administreras dosen på antingen 2,5 mg/kg eller 1,9 mg/kg (eller annan justerad dos). Deltagarna kommer att behandlas med belantamab mafodotin som monoterapi tills sjukdomsprogression, dödsfall, oacceptabel toxicitet, återkallande av samtycke eller avslutas av studien, beroende på vilket som inträffar först. Denna studie kommer att inkludera en screeningsfas, behandlingsfas, uppföljningsfas och en efteranalysfas för fortsatt behandling (PACT). Studiens totala varaktighet är cirka 48 månader.

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.

Blood samples were collected for PK analysis of belantamab mafodotin Cys-mcMMAF. 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.
Pre-dose, end of infusion (EOI), start of infusion (SOI)+2hour (h), SOI+4h, SOI+8h and SOI+24h on Cycle(C) 1 Day(D) 1 and C3D1; Anytime on C1 D4, D8, D15, D22; Anytime on C3 D4, D8, D15, D22; Pre-dose on C2D1 and C4D1.
Part 2: Area Under the Concentration-time Curve During the Dosing Interval up to 168 Hours (AUC (0-168h)) Following Administration of Belantamab Mafodotin (Cys-mcMMAF)
Tidsram: Pre-dose, end of infusion (EOI), start of infusion (SOI)+2hour (h), SOI+4h, SOI+8h and SOI+24h on Cycle(C) 1 Day(D) 1 and C3D1; Anytime on C1 D4, D8, and D15; Anytime on C3 D4, D8, and D15
Blood samples were collected for PK analysis of belantamab mafodotin Cys-mcMMAF. In cases where the nominal Day 8 sample was collected prior to 168 hours and earlier time points did not permit reliable extrapolation to 168 hours, a later sample (e.g., Day 15) with a measurable concentration was used to support estimation of the concentration at 168 hours. Outcome data are reported only for AUC over 0-168 hours.

Part 1 and Part 2: Change From Baseline (CFB) in Vital Signs: Diastolic Blood Pressure (DBP) and Systolic Blood Pressure (SBP)
Tidsram: Baseline (Day 1) and up to approx. 236 weeks
Blood pressures (DBP and SBP) were measured after resting for at least 5 minutes in a supine or semi-recumbent position. Baseline (Day 1) was defined as latest pre-dose assessment with a non-missing value, including unscheduled visits. Change from Baseline was calculated as post-dose visit value minus Baseline value. The "0" participants analyzed represents that data was not collected or available for analysis at that particular time point for the respective Arms/Groups.

Part 1 and Part 2: Change From Baseline (CFB) in Vital Signs: Heart Rate
Tidsram: Baseline (Day 1) and up to approx. 236 weeks
Heart rate was measured after resting for at least 5 minutes in a supine or semi-recumbent position. Baseline (Day 1) was defined as latest pre-dose assessment with a non-missing value, including unscheduled visits. Change from Baseline was calculated as post-dose visit value minus Baseline value.

Tidsram: Up to approximately 236 weeks
An AE is defined as any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. AEs were coded using the Medical Dictionary for Regulatory Activities (MedDRA) coding system.

Part 1 and Part 2: Number of Participants With Worst Case Hematology Results by Maximum Grade Increase Post-Baseline Relative to Baseline
Tidsram: Baseline (Day 1) and up to approx. 236 weeks
Blood samples were collected for the analysis of hematology parameters and are categorized in alignment with Common Terminology Criteria for Adverse Events (CTCAE) version 5 as Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; and Grade 4: life-threatening consequences. Higher grade indicates greater severity. An increase in grade was defined relative to the Baseline grade. Participants with missing baseline values are assumed to have baseline value of grade 0. Increase to a maximum grade of 3 and 4 is presented. Baseline is defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Worst Case Post-Baseline includes all scheduled and unscheduled visits post baseline.

Data is presented as "No Change/Decreased" and "Any Increase" that includes Increase to TRACE, Increase to 1+, Increase to 2+ and Increase to 3+ indicating proportional concentrations in the urine sample.
