Primary Outcome Measures :
- Percentage of Participants With Complete Response (CR) Rate [ Time Frame: From enrollment until the primary analysis completion date of 12 Sep 2022; the median duration of exposure was approximately 7 weeks ]The complete response rate (CR + CRi [complete response with incomplete peripheral recovery]) was defined as the percentage of participants achieving complete response (CR + CRi) assessed by the investigator per National Comprehensive Cancer Network (NCCN) guidelines version 1.2018 criteria. CR was defined as <5% blasts in a bone marrow aspirate (BMA) with spicules; no circulating blasts (ALL)/no blasts with Auer rods (AML) or extramedullary disease, no lymphadenopathy, splenomegaly, skin/gum infiltration/testicular mass/central nervous system involvement (ALL), trilineage hematopoiesis (ALL); Absolute neutrophil count (ANC) >=1000/microliter (mcL); platelets >100000/mcL; red blood cell transfusion independence. If the physician documented transfusion dependency related to study treatment and not to the participant's underlying disease, CRi was reported. CRi met the same criteria as for CR, except neutrophils and/or platelets recovery (ANC <1000/mcL or platelets <100000/mcL).
Secondary Outcome Measures :
- Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs) [ Time Frame: From the time of the first treatment administration (Day 1) up to 30 days after the last treatment (maximum duration of exposure of 13.1 weeks for B-ALL cohort, 10.7 weeks for T-ALL cohort and 7.1 weeks for AML cohort) ]An AE was defined as any untoward medical occurrence in a participant temporally associated with the use of study treatment, whether or not considered related to the study treatment. SAEs were any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a medically important event. TEAEs were defined as an AE which occurred after the first dose of study treatment administration until the last dose plus 30 days, or until the start of hematological recovery period or a new anti-leukemia/lymphoma therapy, whichever occurred first.
- Number of Participants With Infusion Reactions (IRs) [ Time Frame: From the time of the first treatment administration (Day 1) up to 30 days after the last treatment (maximum duration of exposure of 13.1 weeks for B-ALL cohort, 10.7 weeks for T-ALL cohort and 7.1 weeks for AML cohort) ]An IR was an AE related to isatuximab typically with onset within 24 hours from the start of the isatuximab infusion and was reported by the investigator.
- B-ALL and T-ALL: Area Under the Concentration Time Curve (AUC) of Isatuximab [ Time Frame: From Week 0 to Week 1, Week 0 to Week 5, and Week 0 to Week 10 ]Plasma samples were collected at specified timepoints to determine the AUC of isatuximab.
- AML: AUC of Isatuximab [ Time Frame: From Week 0 to Week 1, Week 0 to Week 3, and Week 0 to Week 8 ]Plasma samples were collected at specified timepoints to determine the AUC of isatuximab.
- B-ALL and T-ALL: Plasma Concentration Reached by Isatuximab Before Next Dose Administration (Ctrough) [ Time Frame: Cycle 1 Day 8, Cycle 1 Day 15, Cycle 1 Day 22, Cycle 1 Day 29, Cycle 2 Day 43, Cycle 2 Day 57 ]Plasma samples were collected at specified timepoints to determine the Ctrough of isatuximab.
- AML: Plasma Concentration Reached by Isatuximab Before Next Dose Administration (Ctrough) [ Time Frame: Cycle 1 Day 8, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 2 Day 15 ]Plasma samples were collected at specified timepoints to determine the Ctrough of isatuximab.
- B-ALL and T-ALL: Concentrations at the End of Infusion (Ceoi) of Isatuximab [ Time Frame: At end of infusion on Cycle 1 Days 1 and 29 ]Ceoi is the plasma concentration observed at the end of intravenous infusion of isatuximab.
- AML: Ceoi of Isatuximab [ Time Frame: At end of infusion on Cycle 1 Days 1 and 15 ]Ceoi is the plasma concentration observed at the end of intravenous infusion of isatuximab.
- Number of Participants With Negative Minimal Residual Disease (MRD) [ Time Frame: From screening until the study completion date, approximately 46 months ]MRD assessment was performed by next generation sequencing (NGS) using clonoSEQ and T-cell receptor (TCR) assays for B-ALL and T-ALL cohorts respectively. It was performed by flow cytometry for AML cohort. Number of participants with CR or CRi who achieved negative MRD in bone marrow and blood were analyzed.
- Overall Response Rate (ORR) [ Time Frame: From enrollment until the primary analysis completion date of 12 Sep 2022; the median duration of exposure was approximately 7 weeks ]ORR:Percentage of participants with CR/CRi or partial response (PR) for blood and bone marrow disease based on NCCN guideline. CR: <5% blasts in BMA with spicules; no circulating blasts (ALL)/no blasts with Auer rods (AML) or extramedullary disease, no lymphadenopathy, splenomegaly, skin/gum infiltration/testicular mass/central nervous system involvement (ALL), trilineage hematopoiesis (ALL);ANC >=1000/mcL; platelets >100000/mcL; RBC transfusion independence. If the physician documented transfusion dependency related to study treatment;not to participant's underlying disease, CRi was reported. CRi met the same criteria as CR, except neutrophils and/or platelets recovery (ANC <1000/mcL or platelets <100000/mcL). PR: >50% decrease in the sum of the product of the greatest perpendicular diameters of the mediastinal enlargement. For participants with a previous positive positron emission tomography (PET) scan, a post-treatment PET was to be positive in at least 1 previously involved site.
- Overall Survival (OS) [ Time Frame: From first study treatment administration up to death due to any cause, approximately 45 months ]Overall survival was defined as the time interval from the date of first study treatment administration to death from any cause.
- Event-Free Survival (EFS) [ Time Frame: From study treatment administration up to the date of first documented disease progression or death due to any cause, approximately 45 months ]EFS was defined as the time interval from the date of first study treatment administration to the date of the first of: completion or going off protocol induction/consolidation therapy without CR, relapse from CR, or death due to any cause.
- Duration of Response (DoR) [ Time Frame: From first documented response up to the date of first documented disease progression or death due to any cause, approximately 45 months ]Duration of response was defined as the time from the date of the first response to the date of first disease progression or death from any cause, whichever happens first.
- Cluster of Differentiation (CD)38 Receptor Density [ Time Frame: Pre-dose on Day 1 ]Blood samples were collected to assess CD38 receptor density as a predictive biomarker. It was assessed across complete responders and non-complete responders. The Antibody Binding Capacity (ABC) was calculated using the following equation: ABC = 10^(Logarithm(Mean Fluorescence Intensity)*a+b) where "a" was the slope and "b" was the Y-intercept of the calibration curve equation. Specific and absolute quantitative values (specific antibody-binding capacity [sABC]) of binding of the selected antibodies were calculated after subtraction of the negative isotypic immunoglobulin G (IgG) control.
- CD38 Receptor Occupancy [ Time Frame: Pre-dose on Day 15 ]Blood samples were collected to assess CD38 receptor occupancy as a pharmacodynamics marker. It was assessed across complete responders and non-complete responders. Multicolor flow cytometry assay was validated for CD38 receptor occupancy (CD38RO) quantification, based on the use of two murine monoclonal antibodies (MAbs), one competing with SAR650984 to determine the number of free CD38 receptors (MAb1) and one recognizing a different binding epitope on CD38 to measure the total number of receptors (MAb2) at the cell surface of the cancer cells. Cells were tagged with either MAb1 (Tube #1) or MAb2 (Tube #2). The percentage RO was calculated using the following equation: % CD38RO = [(sABC MAb2 - sABC MAb1)/sABC MAb2] X 100.
