Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy, Therapy

The primary objective is to evaluate the very good partial response rate (VGPR) in patients with newly diagnosed NTE multiple myeloma

Secondary objectives 8

1. To assess the survival according to IMWG
2. To evaluate the response rate
3. To evaluate the safety profile associated to the association IsVRd
4. To evaluate patient satisfaction with SC isatuximab
5. To evaluate assessment of abilities and life quality of patients
6. FOR MIBAPIX AND PK- ADA-To assess the PK profile and the potential immunogenicity of isatuximab when given by SC route in combination with RVd in NDMM patients
7. FOR MIBAPIX AND PK- ADA-To evaluate Apixaban exposition in newly diagnosed non-frail MM patients.
8. FFOR MIBAPIX AND PK- ADA-To compare Apixaban exposition to BENEFIT/APIXABOR patients and to correlate the plasma level of Apixaban according to myeloma treatments.
