Phase III Study of Daratumumab/rHuPH20 (NSC-810307) + Lenalidomide or Lenalidomide as Post-Autologous Stem Cell Transplant Maintenance Therapy in Patients With Multiple Myeloma (MM) Using Minimal Residual Disease to Direct Therapy Duration (DRAMMATIC Study)
The purpose of this study is to compare overall survival (OS) between the two treatment arms with lenalidomide as the comparator arm and lenalidomide + daratumumab/rHuPH20 as the experimental arm in post-autologous transplant multiple myeloma (MM) patients.
- Active Comparator: Lenalidomide
- Experimental: Lenalidomide + Daratumumab/rHuPH20
- Patients must have had a confirmed diagnosis of symptomatic multiple myeloma (See Section 4.1) that required systemic induction therapy prior to autologous stem cell transplantation (ASCT).
- Patients with disease measurable by serum light chain assay alone are eligible (defined as >/= 100 mg/L on involved light chain).
- Patients must be registered to Step 1 prior to registration to Step 2. Registration to Step 1 may take place prior to or after autologous stem cell transplant (ASCT), but after completion of induction therapy.
- Patients must have initiated induction therapy within 12 months prior to registration Step 1 and have received at least two cycles of induction therapy.
- Patients must be willing and able to take DVT prophylaxis (aspirin, low molecular weight heparin, warfarin, or equivalent oral anticoagulation).
- Patients must be >/= 18 and </= 75 years of age at time of registration to Step 1.
- Patients must have history and physical exam within 28 days prior to registration.
- Patients must have Zubrod Performance Status </= 2.
- Patients must have evidence of adequate renal function, as defined by (1) creatinine clearance (CrCl) >/= 30 mL/min., as measured by a 24-hour urine collection, or estimated by the Cockcroft and Gault formula, or (2) serum creatinine < 2.5 mg/dL. Values must be obtained within 28 days prior to registration.
- Patients must have adequate hepatic function defined by the following within 42 days prior to registration:
- Total bilirubin </=1.5 x IULN (institutional upper limit of the norm) AND
- AST and ALT </=3.0 x IULN
- Patients must meet one of the following criteria:
- Be acceptable for transplant per institutional guidelines and the criteria evidencing this must be documented on the S1803 Onstudy Form. (See Appendix 18.3 for standard transplant eligibility guidelines. Note that these are guidelines and not required criteria.) OR
- Have completed autologous stem cell transplant within 180 days prior to registration (see also Section 5.2a).
- Patients with human immunodeficiency virus (HIV) are eligible providing they are on effective antiretroviral therapy and have undetectable viral load at their most previous viral load test and within 6 months prior to registration.
- Patients must be able to take and swallow oral medication (capsules) whole. Patients may not have any known impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of study drug (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection).
- For patients who have not yet received transplant: Patients must be willing and able to return to the transplant center for their assigned treatment after randomization. Note that patients need not have a direct relationship with the transplant center in order to register.
