S1803, Daratumumab/rHuPh20 +/- Lenalidomide as Post-ASCT Maintenance for MM w/MRD to Direct Therapy Duration

NCT04071457

Description:

Patients are enrolled to screening (Reg Step 1) prior to or after ASCT but prior to Reg Step 2. Patients are followed until they will begin Maintenance and then registered to Reg Step 2 (first randomization). Patients are randomized between Lenalidomide for 2 years and Lenalidomide + Daratumumab/rHuPH20. After 2 years of Maintenance, MRD is assessed to guide further therapy. MRD-positive patients will continue with the assigned treatment. MRD-negative patients will be further randomized (Reg Step 3) to either continue or discontinue the assigned treatment. Patients are treated for up to 7 years from Step 2 reg and followed for up to 15 years.

        Healthy Volunteers:No

        Primary Outcome Measures

        Measure:Overall Survival
        Time Frame:From date of intial randomization until death due to any cause, assessed up to 15 years
        Safety Issue:
        Description:Overall survival will evaluated using a weighted log-rank test and will be compared between primary treatment arms. All eligible patients with valid consent will be included in the analysis. Patients last known to be alive are censored at the date of last contact.

        Secondary Outcome Measures

        Measure:Progression Free Survival

        Safety Issue:
        Description:Progression-free survival will evaluated using a weighted log-rank test and will be compared between primary treatment arms. All eligible patients with valid consent will be included in the analysis. Patients last known to be progression-free and alive are censored at the date of last contact.
        Measure:Response (PR or better)
        Time Frame:From date of initial randomization until date of best response while on study treatment.
        Safety Issue:
        Description:Per International Uniform Response Criteria for Multiple Myeloma PR- ≥ 50% reduction in size of soft tissue plasmacytomas & plasma cells; ≥ 50% decrease in serum & reduction in urine M protein ≥ 90% or to < 200 mg/24hr or ≥ 50% decrease in difference in uninvolved & involved serum free light chain levels; VGPR- PR + Serum and urine M proteins detectable by immunofixation but not on electrophoresis or ≥ 90% reduction in serum M protein & urine M protein < 100 mg/24 hrs; uPR- 1 objective status of PR, but confirmation studies are not done, or do not meet the requirements necessary to confirm response; SD- does not meet criteria for sCR, CR, VGPR, PR or PROG; PROG- new or increase in size of existing bone lesions or soft tissue plasmacytomas/ development of hypercalcemia attributable solely to MM/ ≥ 25% increase from baseline/ lowest response level of either serum or Urine M protein, difference in involved & uninvolved serum free light chain level or bone marrow plasma cell percentage.
        Measure:MRD Negativity
        Time Frame:24 months from initial randomization
        Safety Issue:
        Description:The rate of MRD response will be calculated as the number of patients who achieved MRD response divided by the number of eligible patients; patients without a conclusive MRD results will be included as non-responders. Comparisons between arms will be made using a stratified Cochran-Mantel-Haenszel test. MRD data will be collected from the central testing laboratory, including percent of cells detected and total cells collected. Unless the sample is limiting, 5 x 106 events are collected for a standard multiple myeloma MRD sensitivities of 0.0001%. MRD negativity will be defined as no templates observed at a sensitivity of 1 in a million cells assessed, with a minimum of 1 million cells being assessed. MRD positivity will be defined as any templates observed regardless of the number of cells analyzed, or non-diagnostic specimens, including if the reference specimen from diagnosis is not able to be sequenced.
