Isatuximab in Combination With Lenalidomide and Dexamethasone in High-risk Smoldering Multiple Myeloma


Brief description of study

Primary Objectives:

  • Safety run-in: To confirm the recommended dose of isatuximab when combined with lenalidomide and dexamethasone in participants with high-risk smoldering multiple myeloma (SMM)
  • Randomized Phase 3: To demonstrate the clinical benefit of isatuximab in combination with lenalidomide and dexamethasone in the prolongation of progression-free survival when compared to lenalidomide and dexamethasone in subjects with high-risk SMM

Secondary Objectives:

Safety run-in

  • To assess overall response rate (ORR)
  • To assess duration of response (DOR)
  • To assess minimal residual disease (MRD) negativity in participants achieving very good partial response (VGPR) or complete response (CR)
  • To assess time to diagnostic (SLiM CRAB) progression or death
  • To assess time to first-line treatment for multiple myeloma (MM)
  • To assess the potential immunogenicity of isatuximab

Randomized Phase 3 - Key Secondary Objectives:

To compare between the arms

  • MRD negativity
  • Sustained MRD negativity
  • Second progression-free survival (PFS2)
  • Overall survival

Other Secondary Objectives:

To evaluate in both arms

  • CR rate
  • ORR
  • DOR
  • Time to diagnostic (SLiM CRAB) progression
  • Time to first-line treatment for MM
  • Safety and tolerability
  • Pharmacokinetics (PK)
  • Potential of isatuximab immunogenicity
  • Clinical outcome assessments (COAs)

Detailed Study Description

Study duration is expected to be approximately 10 years, including a 28-day screening period, followed by an up to 36-month treatment period, and a follow-up period of approximately 7 years.

Clinical Study Identifier: NCT04270409
