Status: Recruiting

Start: Oct. 2021

Coordinating Investigator: Univ. Prof. Dr. Heinz Ludwig

EudraCT Nummer: 2020-004972-17

ClinicalTrialsID: NCT04891809

Number of patients: 198

Sponsor: AGMT gemeinnützige GmbH

Design

This is a prospective, multicenter, multinational, randomized, open-label, parallel group, 2-arm study evaluating the clinical benefit of isatuximab in combination with lenalidomide and low-dose dexamethasone followed by isatuximab and lenalidomide maintenance therapy as compared to lenalidomide and low-dose dexamethasone followed by lenalidomide maintenance therapy for the treatment of patients with newly diagnosed multiple myeloma 70 years of age or older.

Randomization/treatment arms
After confirmation of eligibility criteria, patients will be randomly assigned in a 1:1 ratio to one of the two arms:

  • Isatuximab in combination with lenalidomide and low-dose dexamethasone (8 cycles) followed by isatuximab and lenalidomide maintenance therapy (IRd/Id), experimental arm
  • Lenalidomide and low-dose dexamethasone (8 cycles) followed by lenalidomide maintenance therapy (Rd/R), control arm
Primary objective:

To demonstrate the benefit of isatuximab in combination with lenalidomide and low-dose dexamethasone followed by isatuximab and lenalidomide maintenance therapy in increasing the proportion of patients with MRD negativity as compared to lenalidomide and low-dose dexamethasone followed by lenalidomide maintenance treatment in patients with newly diagnosed multiple myeloma (NDMM).

Secondary objectives:
  • To evaluate the Overall Response Rate (ORR), Partial Response (PR), Very Good Partial Response (VGPR) and Complete Response (CR) as per International Myeloma Working Group (IMWG) criteria in each arm.
  • To compare the Progression-free (PFS) and Overall Survival (OS) between the two arms.
  • To evaluate the proportion of patients with MRD negativity (defined by NGF [next generation flow] at 10-5) after 12 months (13 cycles) of maintenance treatment.
  • To evaluate the Time to Progression (TTP) in each arm.
  • To evaluate the PFS in high risk cytogenetic population defined as patients carrying a) del(17p), t(4;14), t(14;16) in each arm and b) the same aberrations plus amp1q21.
  • To evaluate the Duration of Response in each arm.
  • To evaluate safety in both treatment arms.
  • To assess disease-specific and a generic health-related quality of life (HRQL), disease and treatment-related symptoms, health state utility and health status.
  • To evaluate PFS of potential second line therapy.

Synopsis

Short title: DSMM_XVII

Title: Elotuzumab (E) in Combination with Carfilzomib, Lenalidomide and Dexamethasone (E-KRd) versus KRd prior to and following Autologous Stem Cell Transplant in Newly Diagnosed Multiple Myeloma and Subsequent Maintenance with Elotuzumab and Lenalidomide versus Single-Agent Lenalidomide

Status: active, not recruiting

Start: Q3 2019 (in Austria)

Coordinating Investigator: Assoc. Prof. Dr. Wolfgang Willenbacher (Austria)

EudraCT Nummer: 2017-001616-11

ClinicalTrialsID: NCT03948035

Number of patients: 576 (international)

Sponsor: University Hospital Würzburg in cooperation with DSMM (Deutsche Studiengruppe Multiples Myelom) and AGMT gemeinnützige GmbH (Sponsor representative in Austria)

Design

This is an interventional, multicentre, open-label, randomized phase III trial with two parallel arms to compare two different regimens. Quadruple elotuzumab in combination with carfilzomib, lenalidomide, and dexamethasone [E-KRd] versus triple carfilzomib, lenalidomide, and dexamethasone [KRd]) is given during induction treatment prior to ASCT and as consolidation treatment after ASCT in patients suffering from newly diagnosed multiple myeloma according to the updated IMWG criteria.

Consolidation treatment is followed by maintenance treatment (elotuzumab in combination with lenalidomide versus lenalidomide monotherapy).

Patients are randomized in a 1:1 ratio to be administered 6 cycles induction treatment, either E-KRd (Arm A) or KRd (Arm B).

After three cycles of induction therapy cyclophosphamide (4.5 g/m2 BSA) is given for stem cell mobilisation (Arm A and Arm B) followed by stem cell harvest. In case of failure, a second attempt of stem mobilization therapy is at discretion of the local investigator.

All patients who obtain at least stable disease (SD) at the restaging following six cycles of induction treatment will proceed to high-dose melphalan chemotherapy followed by ASCT.

The patients are given four cycles of consolidation treatment, patients in Arm A receive E-KRd and patients in Arm B receive KRd. Another restaging is performed within two weeks after Cycle 4 Day 28 of consolidation treatment and before the start of maintenance treatment.

As maintenance treatment the combination of elotuzumab and lenalidomide continuously is administered in Arm A and continuous lenalidomide monotherapy in Arm B until progression or occurrence of unacceptable toxicity whichever period is shorter.

Primary endpoints:

For the induction phase:

  • Rate of patients who have VGPR or better response according to IMWG criteria and are MRD-negative as assessed by flow cytometry following six cycles of induction treatment

GMMG-HD8 / DSMM XIX

A randomized phase III non-inferiority trial assessing lenalidomide, bortezomib and dexamethasone induction therapy with either intravenous or subcutaneous isatuximab in transplant-eligible patients with newly diagnosed multiple myeloma

Synopsis

Short title: GMMG-HD8 / DSMM XIX

Title: A randomized phase III non-inferiority trial assessing lenalidomide, bortezomib and dexamethasone induction therapy with either intravenous or subcutaneous isatuximab in transplant-eligible patients with newly diagnosed multiple myeloma

Status: recruiting

Start: Q4 2023 (in Austria)

Coordinating Investigator: Univ. Prof. Dr. Richard Greil (Austria)

EudraCT Nummer: 2022-000996-38

ClinicalTrialsID: NCT05804032

Number of patients: 514 (international)

Sponsor: Ruprecht-Karls-Universität Heidelberg in cooperation with GMMG (German-Speaking Myeloma Multicenter Group) and DSMM (Deutsche Studiengruppe Multiples Myelom) and AGMT gemeinnützige GmbH (Sponsor representative in Austria)

Design

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

Investigational Medicinal Product: Isatuximab, subcutaneous administration via a wearable injector system.

Randomization: Patients are randomized in one of 2 study arms (A or B) before induction therapy. Patients randomized in arm A will receive 3 cycles of the monoclonal antibody isatuximab intravenously, combined with RVd regimen (Lenalidomide, Bortezomib, Dexamethasone). Each cycle will last for 42 days. Patients in arm B will receive 3 cycles RVd plus isatuximab subcutaneously. After induction therapy, patients will receive standard intensification (usually cyclophosphamide-based mobilization therapy, stem cell collection and high-dose melphalan followed by autologous stem cell transplantation (HDM/ASCT)). End of study will be after the first HDM/ASCT.

Primary endpoints:

Demonstration of non-inferiority of subcutaneous (SC) isatuximab compared to intravenous (IV) isatuximab, both in combination with RVd, with respect to rates of VGPR or better after induction therapy (according to standard International Myeloma Working Group (IMWG) response criteria).

Key Secondary endpoints:
  • Comparison of patient-reported outcomes (PRO) regarding route of administration of isatuximab (SC vs. IV) on induction therapy as assessed by modified CTSQ (modified 9-item questionnaire).
  • Non-inferiority of rates of MRD negativity (assessed by NGS from BMA; sensitivity 10^-5) independent of standard IMWG response after induction therapy.
