Phase 1/2 Dose Escalation and Efficacy Study of Anti-CD38 Monoclonal Antibody in Patients With Selected CD38+ Hematological Malignancies
To determine the maximum tolerated dose (MTD)/maximum administered dose (MAD) of SAR650984.
To evaluate the activity of single-agent SAR650984 at different doses/schedules and to further evaluate the overall response rate (ORR) of SAR650984 at the selected dose.
- To characterize the global safety profile including cumulative toxicities.
- To evaluate the pharmacokinetic (PK) profile of SAR650984 in the proposed dosing schedule(s).
- To assess the pharmacodynamics (PD), immune response, and preliminary disease response.
- To evaluate safety of SAR650984.
- To evaluate the efficacy of SAR650984 as measured by duration of response, clinical benefit rate, progression free survival, overall survival.
- To evaluate patient reported outcomes.
- To evaluate the PK profile.
- To evaluate the immunogenicity of SAR650984.
- To investigate the relationship between CD38 receptor occupancy and CD38 receptor density and parameters of clinical response.

Phase 1: Accelerated dose escalation phase (1 patient/cohort), two administrations every two weeks (Q2W) per dose cohort. Followed by basic dose escalation phase evaluating SAR650984 administration weekly (QW) and Q2W with 3-6 patients/cohort treated until disease progression or unsatisfactory safety. Cohort 1-10 will enroll patients with CD38+ hematological malignancies and cohort 11 onwards will enroll patients with multiple myeloma only. Two expansion cohorts will evaluate the recommended Phase 2 dose (RP2D) in standard risk and high risk multiple myeloma patients.
Phase 2: Stage 1 will further evaluate four randomized arms. Arm 1: Dose 1 Q2W, Arm 2: Dose 2 Q2W, Arm 3: Dose 2 Q2W for 2 cycles then every 4 weeks (Q4W), Arm 4: Dose 3 QW for 1 cycle then Q2W. Stage 2 will use the dose and schedule determined from Stage 1.
Pharmaceutical form: solution for infusion
Route of administration: intravenous
The Phase 1 study duration for an individual patient will include a screening period for inclusion of up to 2 weeks, treatment with SAR650984 QW (every week) or Q2W (every 2 weeks) unless discontinued earlier due to safety or disease progression. Patients will be followed for a minimum of 30 days following the last use of study drug or more than 30 days in case of unresolved toxicity, or up to initiation of another anticancer treatment.
The Phase 2 study duration for an individual patient will include a screening period for inclusion of up to 3 weeks, treatment with SAR650984 Q2W or Q4W (every 4 weeks) unless discontinued earlier due to safety or disease progression. Patients will be followed every 3 months following the last use of study drug until death or study cutoff whichever comes first.
