Trial on the Effect of Isatuximab to Lenaliodomide/Bortezomib/Dexamethasone (RVd) Induction and Lenalidomide Maintenance in Patients With Newly Diagnosed Myeloma (GMMG HD7)

Brief description of study

Trial in patients with newly diagnosed myeloma to evaluate the effect of isatuximab in induction therapy with lenalidomide/bortezomib/dexamethasone (RVd) and in lenalidomide maintenance treatment

Detailed Study Description

Prospective, multicentre, randomised, parallel group, open, phase III clinical trial, for patients with confirmed diagnosis of untreated multiple myeloma requiring systemic therapy.

Investigational Medicinal Products: Isatuximab, Lenalidomide

  1. Randomization: Patients are randomized in one of 2 study arms (IA or IB) before induction therapy. Patients randomized in arm IA will receive 3 cycles RVd (Bortezomib (Velcade), Lenalidomide (Revlimid, each cycle is 42 days), Dexamethasone). Patients in arm IB will additionally receive the monoclonal antibody Isatuximab in the 3 cycles RVd. After induction therapy patients undergo intensifying therapy according to GMMG standard (usually mobilization therapy followed by stem cell collection and autologous stem cell transplantation).
  2. Randomization: Before maintenance treatment patients are randomized in one of 2 study arms (IIA and IIB): Patients in arm IIA receive Lenalidomide maintenance therapy for three years, patients in arm IIB receive additional Isatuximab.

There are two primary objectives:

  1. to compare the induction regimen (IA vs IB) regarding minimal residual disease (MRD) negativity after induction (assessed by flow cytometry; sensitivity at least 1e-5)
  2. to compare the maintenance strategies (arms IIA vs IIB) regarding progression-free survival (PFS), defined as time from 2nd randomization (prior to maintenance therapy) to progression or death from any cause whichever occurs first.

The duration of the trial for each patients is expected to be 45-48 months (induction and intensification treatment: 6-9 months, 3 months rest between intensification and start of maintenance phase 36 months).

Clinical Study Identifier: NCT03617731
