About this study
Official title: Phase 2 Trial of Belantamab Mafodotin Consolidation Treatment in Patients With Multiple Myeloma and MRD Positivity After Autologous Stem Cell Transplantation
This phase II trial investigates the effect of belantamab mafodotin and lenalidomide on minimal residual disease negative rates in patients with multiple myeloma with minimal residual disease positive after stem cell transplant. Belantamab mafodotin is a monoclonal antibody, called belantamab, linked to a chemotherapy drug, called mafodotin. Belantamab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as B-cell maturation antigen (BCMA) receptors, and delivers mafodotin to kill them. Lenalidomide may help block the formation of growths that may become cancer, and is used as a standard of care treatment for multiple myeloma. Giving belantamab mafodotin and lenalidomide may help to maintain minimal residual disease negativity in patients with multiple myeloma.
Read the detailed description
PRIMARY OBJECTIVE:
- Assess the minimal residual disease (MRD) negative rate after 6 cycles of post autologous stem cell transplant consolidation with belantamab mafodotin and lenalidomide.
SECONDARY OBJECTIVE:
- Assess sustained MRD negative rate, progression free survival (PFS) and overall survival (OS).
OUTLINE:
Patients receive belantamab mafodotin intravenously (IV) over 30 minutes on day 1 and lenalidomide orally (PO) once daily (QD) on days 1-28. Treatment repeats every 8 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 12 weeks and the periodically for up to 5 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Minimal residual disease (MRD) negative rate
A 90% confidence interval about true 6-month post-consolidation MRD negative rate will be obtained.
Measured: After 6 cycles of post-transplant consolidation with belantamab mafodotin and lenalidomide (1 cycle = 8 weeks)
Secondary outcomes (3)
Sustained MRD negative rate
Measured: At 1 year after end of consolidation
Progression-free survival
Will be summarized using standard Kaplan-Meier methods, with estimates of the median obtained with 90% confidence intervals.
Measured: Time from the start of consolidation therapy until disease progression death, due to disease, or last disease evaluation, assessed up to 5 years
Overall survival
Will be summarized using standard Kaplan-Meier methods, with estimates of the median obtained with 90% confidence intervals.
Measured: Time from the start of consolidation until death due to any cause or last follow-up, assessed up to 5 years
