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

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over

  • (3) months of screening.
3. Class III or IV heart failure as defined by the New York Heart Association functional classification system.16. 4. Uncontrolled hypertension (blood pressure that remains above goal despite the concurrent use of three antihypertensive drug classes).
  • - Participant must not have known HIV infection.

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
