Phase 1RecruitingM.D. Anderson Cancer CenterNCT05055063Data as of May 2026

Treatment: Belantamab mafodotinThis is a single-center, single arm, phase I study designed to determine the safety and find the recommended Phase 2 dose (RP2D) or maximum dose level (MTD) of Belantamab Mafodotin in patients with high-risk smoldering multiple myeloma. The study will have a dose-finding part and a dose-expansion part. The maximum number of enrolled patients will be 30 with 18 patients for the dose-finding part and 12 patients for the dose-expansion part. Once we determine the MTD or RP2D in the dose-finding part, we will enroll and treat 12 additional patients at the MTD or RP2D in the expansion part. Efficacy will be assessed through the overall response rate (ORR) at the end of the study. With the limited number of patients for the dose-expansion part, we will not have formal futility monitoring rule.

Lab requirements

Blood counts

Absolute neutrophil count (ANC) ≥ 1.0 x 10^9 /L, hemoglobin more or equal than 2 grams below the institutional level of normal and platelet count ≥ 90 x 10^9/L. Platelet and blood transfusions are allowed on protocol.

Kidney function

Creatinine clearance (CrCl) ≥ 30 ml/min. CrCl will be calculated using the Modification of Diet in Renal Disease (MDRD) equation.
