Minimal Residual Disease Guided Maintenance Therapy With Belantamab Mafodotin and Lenalidomide After Autologous Hematopoietic Cell Transplantation in Patients With Newly Diagnosed Multiple Myeloma

To increase the conversion rate from MRD-positive to MRD-negative CR in patients with newly diagnosed multiple myeloma (NDMM) receiving post-transplant maintenance therapy with belantamab mafodotin plus lenalidomide.

Study Overview

• Status: Recruiting
• Conditions: Myeloma Multiple
• Intervention / Treatment: Drug: Belantamab mafodotin; Drug: Lenalidomide

Detailed Description

Primary Objective:

-To increase the conversion rate from MRD-positive to MRD-negative CR in patients with newly diagnosed multiple myeloma (NDMM) receiving post-transplant maintenance therapy with belantamab mafodotin plus lenalidomide.

Secondary Objectives:

• To determine the safety and tolerability of belantamab mafodotin plus lenalidomide maintenance therapy after auto-HCT.
• To increase the overall MRD-negative CR rate in patients with NDMM receiving post-auto-HCT maintenance therapy with belantamab mafodotin plus lenalidomide.
• To determine the PFS and OS in patients who discontinue maintenance therapy after achieving sustained MRD-negative CR. Sustained MRD-negative CR is defined as MRD-negative status in two assessments, at least 1-year apart, without any MRD-positive status in between.
• To determine the PFS with belantamab mafodotin plus lenalidomide maintenance therapy after auto-HCT in patients with NDMM.
• To determine the OS with belantamab mafodotin plus lenalidomide maintenance therapy after auto-HCT in patients with NDMMM.

• Patient agrees to enroll in the lenalidomide REMS program.
• Woman of child-bearing potential (WOCPB) must abstain from hetersosexual sexual contact or agrees to use a contraceptive method that is highly effective (with a failure rate of <1% per year), preferably with low user dependency (as described in Appendix C), plus one additional effective method at least 28 days before starting therapy (for lenalidomide), during the intervention period, at least 28 days after the last dose of lenalidomide and at least 4 months after the last dose of belantamab mafodotin, and agrees not to donate eggs (ova, oocytes) for reproduction during this period. The investigator should evaluate the effectiveness of the contraceptive method in relation to the first dose of the study intervention.

A WOCBP must have a negative highly sensitive serum pregnancy test (as required by local regulations) within 10-14 days and also within 24 hours before the first dose of the study intervention.

Nonchildbearing potential is defined as follows (by other than medical reasons):

• ≥ 45 years of age and has not had menses for >1 year.
• Patients who have been amenorrhoeic for <2 years without a history of a hysterectomy and oophorectomy must have a follicle-stimulating hormone value in the postmenopausal range upon screening evaluation.
• Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. 9. Male participant agrees to contraceptive use that should be consistent with institutional guidelines regarding the methods of contraception for those participating in clinical studies.

Male participants are eligible to participate if they agree to the following during the intervention period and for 6 months after the last dose of study treatment to allow for clearance of any altered sperm:

• Refrain from donating sperm during treatment (including dose interruptions) and for 4 weeks after their last dose of lenalidomide.

PLUS, either:

• Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent.

OR Must agree to use contraception/barrier as detailed in Appendix C.

• All prior auto-HCT- related toxicities (defined by National Cancer Institute - Common Toxicity Criteria for Adverse Events (NCI-CTCAE), version 5 must be ≤ Grade 1 at the time of enrollment except for alopecia, fatigue, and amenorrhea.

Exclusion Criteria:

• History of progressive disease at any time before starting maintenance.
• Patients with smoldering MM (IMWG criteria, Appendix F.).

• Participant must not have presence of active renal condition (infection, requirement for dialysis or any other condition that could affect participant's safety). Participants with isolated proteinuria resulting from MM are eligible, provided they fulfil inclusion criteria.
• Current corneal or epithelial disease (except mild punctate keratopathy; see Appendix E.).
