Detailed Description

The aim of the study is to investigate the safety and efficacy of daratumumab added to a standard induction regimen of bortezomib, cyclophosphamide and dexamethasone (VCD). A secondary aim is to assess the efficacy of maintenance therapy until progression using daratumumab in combination with bortezomib and dexamethasone. Thirdly the efficacy of a daratumumab-containing regimen at first relapse shall be tested following a daratumumab-containing first line regimen. Rationale: VCD has been established as a standard of care for first line therapy of transplant-eligible patients in Germany. The favorable toxicity profile makes this regimen also suitable for transplant-ineligible patients. Daratumumab has shown to be safe and efficacious in a variety of combinations such as with VMP, Vd or Rd. Using a reduced dose of cyclophosphamide the study shall investigate safety and efficacy of Dara-VCD in the transplant-ineligible patient population. Maintenance therapy has become standard of care in transplant-eligible and non-eligible patients. However, there is uncertainty whether a single agent maintenance is sufficient or whether a combination therapy is necessary. In this study the safety and efficacy of maintenance with daratumumab in combination with bortezomib and dexamethasone will be assessd with a focus on MRD negativity as a novel endpoint. The multitude of treatment options at first relapse has generated the need to find an optimal sequence of therapy regimens in first and second line. In particular it is unclear whether the efficacy of daratumumab at relapse is affected by its prior use as part of the first line treatment. Patients in this study will relapse on or after a daratumumab-containing maintenance and shall receive DRd at first relapse. In the POLLUX study patients received DRd but had no prior exposure to daratumumab. Therefore, patients included into the POLLUX study can serve as an indirect control cohort for the present study. If in the present study the PFS after DRd is similar to the PFS of the comparable cohort from the POLLUX study, the assumption is supported that prior exposure to daratumumab does not impair the activity of a subsequent daratumumab-containing regimen at relapse. In addition, the overall efficacy of the whole protocol treatment will be assessed by analyzing PFS2 after relapse from study inclusion (PFS2).


  • Drug: Daratumumab
    • Daratumumab added to induction regimen of bortezomib, cyclophosphamide and dexamethasone (VCD), to bortezomib and dexamethasone during maintenance and to lenalidomide and dexamethasone at progression/relapse.

Arms, Groups and Cohorts

  • Experimental: Daratumumab added to VCd in induction, Vd in maintenance and Rd at relapse
    • Daratumumab at standard dose of 1800 mg will be administered subcutaneously at weekly intervals in cycles 1-2 and every 2 weeks in cycles 3-6 and every 4 weeks in cycles 7-8 together with VCD using bortezomib weekly s.c. for 8 cycles of 28 days each, cyclophosphamide i.v. at 500 mg/m2 on d1 of every cycle and dexamethasone p.o. at 20 mg per week. Maintenance will be daratumumab subcutaneously every 4 weeks with bortezomib s.c. and dexamethasone 20 mg every 2 weeks until progression or intolerance. At relapse/progression treatment will be daratumumab 1800 mg subcutaneously weekly during cycle 1-2, every 2 weeks in cycle 3-6 and every 4 weeks thereafter together with lenalidomide 25 mg p.o. day 1-21 and dexamethasone 20-40 mg weekly.
