Study of Isatuximab Combined With Bortezomib + Cyclophosphamide + Dexamethasone (VCD) and Bortezomib + Lenalidomide + Dexamethasone (VRD) in Newly Diagnosed Multiple Myeloma (MM) Non Eligible for Transplant or No Intent for Immediate Transplantation

Registration Number
NCT02513186
Lead Sponsor
Sanofi
Brief Summary

Primary Objectives:

* VCDI cohort:

* To determine the maximum tolerated dose (MTD) and recommended dose (RD) of SAR650984 isatuximab when administered in combination with bortezomib (VelcadeĀ®) , cyclophosphamide, and dexamethasone (VCDI) based on the dose-limiting toxicity(ies) (DLTs) observed in patients with newly diagnosed multiple myeloma non-eligible for transplantation

* To evaluate safety and preliminary efficacy (overall response rate and complete response rate) of isatuximab administered at the selected dose in combination with bortezomib based regimin VCDI according to IMWG criteria.

* VRDI Part A cohort and Part B cohort:

* To evaluate the preliminary efficacy (complete response \[CR\] rate) of isatuximab administered at the selected dose in combination with bortezomib based regimen: VRDI, (bortezomib, lenalidomide, dexamethasone) according to IMWG criteria in adult patients with newly diagnosed MM non eligible for transplantation or no intent for immediate transplantation.

Secondary Objectives:

* VCDI cohort:

* To characterize the overall safety profile of SAR650984 in combination with VCD regimen, including cumulative toxicities.

* To characterize the pharmacokinetic (PK) profile of SAR650984/isatuximab and each combination drug in VCDI regimen.

* To evaluate the immunogenicity of SAR650984 in combination treatments.

* To evaluate the preliminary efficacy of VCDI regimen in terms of duration of response and progression-free survival.

* To assess the relationship between clinical effects (adverse event \[AE\] and/or tumor response) and CD38 receptor density.

* VRDI Part A cohort and Part B cohort:

* To characterize the overall safety profile of isatuximab in combination with VRD regimen.

* To evaluate the infusion duration (only applicable for VRDI Part B cohort)

* To characterize the PK profile of isatuximab and each combination drug in VRDI regimen.

* To evaluate the immunogenicity of isatuximab in combination treatments.

* To evaluate the preliminary efficacy of VRDI regimen in terms of ORR, DOR, and PFS.

* To evaluate the impact of M protein measurement without isatuximab interference (via the SEBIA HYDRASHIFT 2/4 isatuximab IFE test) on CR and BOR assessment.

* To assess the relationship between clinical effects (AE and/or tumor response) and CD38 receptor density (only applicable for VRDI Part A cohort).

* To assess MRD negativity rate in patients achieving a CR or VGPR and explore correlation with clinical outcome.

Detailed Description

The duration of the study for an individual patient will include:

* A period to assess eligibility (screening or baseline period) of up to 3 weeks for VCDI cohort, up to 28 days for VRDI cohort;

* for patients in the VCDI cohort: a treatment period including up to 12 induction treatment cycles (50-week duration).

* for patients in the VRDI cohort: a treatment period including up to 4 induction cycles (24 week duration).

* Following induction, both cohorts have maintenance periods consisting of 4 week cycles until progression, unacceptable AE, or patient willingness to discontinue and an end-of-treatment visit at least 30 days following the last administration of treatment.

* Patients that discontinue therapy for reasons other than progression will have follow-up visits until progression or until the patient receives another anticancer therapy, whichever is earlier.

IsatuximabdexamethasoneVCDI cohort: Isatuximab (escalating dose) + bortezomib + cyclophosphamide + dexamethasone (VCDI): Induction phase will be 50 weeks (12 cycles). The duration of a cycle will be 42 days (6 weeks) for Cycle 1 (C1) and 28 days (4 weeks) for subsequent cycles. The duration of a cycle of the maintenance phase will be 28 days (4 weeks). After C12, isatuximab will be administered at its initial assigned dose and dexamethasone once every 28 days. VRDI cohort parts A and B: Isatuximab + bortezomib + dexamethasone + lenalidomide (VRDI): Induction phase will be 24 weeks (4 cycles at 6 weeks/cycle). The duration of a cycle of the maintenance phase will be 28 days (4 weeks). Maintenance therapy may continue until disease progression, unacceptable AE or patient willingness to discontinue. VRDI Part A: Enrollment to begin after the VCDI cohort is completed. VRDI Part B: Enrollment to begin after the VRDI part A is completed.
