Lenalidomide, and Dexamethasone With or Without Daratumumab in Treating Patients With High-Risk Smoldering Myeloma

NCT03937635

Description:

This phase III trial studies how well lenalidomide and dexamethasone works with or without daratumumab in treating patients with high-risk smoldering myeloma. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and dexamethasone with daratumumab may work better in treating patients with smoldering myeloma.

Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and dexamethasone with daratumumab may work better in treating patients with smoldering myeloma.

      Therapy [FACT]- General [G]]) from baseline to end of study therapy between arms.

      II. To compare change in FACT-G scores from treatment end to 6-months post-treatment end
      between arms.

      III. To describe changes in FACT-G scores over study therapy and shortly after treatment
      discontinuation and evaluate correlation with survival.

      IV. To evaluate attributes of select patient reported treatment-emergent symptomatic adverse
      events (Patient Reported Outcomes [PRO]-Common Terminology Criteria for Adverse Events
      [CTCAE]) longitudinally.

      V. To derive an overall PRO-CTCAE score at each assessment time point. VI. To measure the
      likelihood of medication adherence (ASK-12) at 6 month intervals throughout treatment.

      I. To evaluate the association of baseline fludeoxyglucose F-18 (FDG)-positron emission
      tomography (PET)/computed tomography (CT) imaging with progression-free survival.

      II. To assess the ability of baseline FDG-PET/CT to predict minimal residual disease status
      after 12 cycles of study therapy and at the end of study therapy.

      III. To describe the results of subsequent FDG-PET/CT imaging studies in the subset of
      patients with baseline abnormal FDG-PET/CT, and to associate these results with
      progression-free survival (PFS).

             receive daratumumab must extend this contraception requirement to 3 months after the
             last dose of protocol treatment). Women must also agree to not breastfeed during this
             same time period. Men must agree to either abstain from sexual intercourse for the
             duration of their participation in the study or use a latex condom during sexual
             contact with a FCBP while participating in the study and for 28 days after the last
             dose of protocol treatment even if they have had a successful vasectomy. Men must also

Time Frame:From randomization to death due to any cause, or censored at date last known alive, assessed up to 15 years
Safety Issue:
Description:Will be estimated using the Kaplan-Meier (KM) method and compared using a stratified log-rank test. Stratified cox proportional hazards regression will produce a treatment hazard ratio estimate.

Secondary Outcome Measures

Measure:Progression-free survival (PFS)
Time Frame:From randomization until disease progression or death due to any cause, or censored at date of last disease evaluation, assessed up to 15 years
Safety Issue:
Description:Will be estimated using the KM method and compared using a stratified log-rank test. Stratified cox proportional hazards regression will produce a treatment hazard ratio estimate.
