About
The goal of this clinical trial is to compare a maintenance therapy consisting of iberdomide and isatuximab with an iberdomide-only regimen. The trial is the subsequent maintenance therapy to GMMG-HD8/DSMM XIX trial for patients with newly-diagnosed multiple myeloma. The main question it aims to answer is:
• Will the addition of isatuximab lead to decreased amounts of measurable myeloma cells in the bone marrow after two years?
Full description
Prospective, multicentre, randomised, parallel group, open, phase III clinical trial for a maintenance therapy, for patients who underwent an induction therapy and autologous stem cell transplantation in the GMMG-HD8/DSMM XIX trial.
Investigational Medicinal Product: Iberdomid (oral), isatuximab (subcutaneous administration via a wearable injector system).
Randomisation will be performed centrally by GMMG/DSMM offices after verification of the eligibility of the patient. At the time of study inclusion, randomization will be performed into arm A (iberdomide) or arm B (iberdomide + isatuximab). Randomization will be stratified by centrally assessed MRD negativity status (yes vs. no vs. unknown); assessed by NGF from BMA; sensitivity of 10^-5; independent of standard IMWG response) and number of HDM/ASCT (single vs. tandem).
Patients randomized in arm A will receive 39 cycles of the drug iberdomide, a Cereblon E3 Ubiquitin Ligase Modulating Drug (CELMoD®) that shares structural similarities to the immunomodulatory compounds (IMiDs) such as thalidomide and lenalidomide. Each cycle will last for 29 days. Patients in arm B will receive the same the 39 cycles of iberdomide plus monoclonal anti-CD38 antibody isatuximab subcutaneously. In both arms, patients will receive 20 mg dexamethasone in cycle 1, on the same days as the isatuximab administration in Arm B. End of study will be after 36 months of the maintenance therapy.
