Primary Objective:

To evaluate the efficacy of isatuximab.

Secondary Objectives:

  • To evaluate the safety profile of isatuximab.
  • To evaluate the duration of response (DOR).
  • To evaluate progression free survival (PFS) and overall survival (OS).
  • To evaluate the pharmacokinetics (PK) of isatuximab in participants with T-ALL or T-LBL.
  • To evaluate immunogenicity of isatuximab in participants with T-ALL or T-LBL.
  • To assess minimal residual disease (MRD) and correlate it with clinical outcome.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study duration per participant included a 3-week screening period, an approximately 1 year of treatment period or until disease progression or discontinuation for any other reason, and a follow-up period of at least 30 days after the last investigational medicinal product administration.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion criteria :

  • Participants must had a known diagnosis of acute lymphoblastic leukemia (ALL) of T cell origin, including T-LBL and T-ALL with extramedullary involvement at relapse confirmed by biopsy.
  • Participants must be previously treated for T-ALL or T-LBL and have relapsed or are refractory to most recent treatment. Participants in first relapse were be eligible regardless of the first remission duration.
  • Participants must had been previously exposed to nelarabine in countries where this drug is available (unless due to a contraindication to its use or administrative issue).
  • No more than 3 prior salvage therapies.

Exclusion criteria:

  • Prior treatment with immunotherapy/investigational agents within 3 weeks, chemotherapy within 2 weeks of study treatment. Must have recovered from acute toxicity before first study treatment administration.
  • Prior stem cell transplant within 4 months and/or evidence of active systemic Graft versus Host Disease and/or immunosuppressive therapy for Graft versus Host Disease within 1 week before the first study treatment administration.
  • Clinical evidence of active central nervous system (CNS) leukemia.
  • T-ALL with testicular involvement alone.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Objective Response
Time Frame: Baseline until disease progression or death (maximum duration: 12.1 weeks)
Objective response was defined as percentage of participants with complete response (CR) or with complete response with incomplete peripheral recovery (CRi) as per National Comprehensive Cancer Network (NCCN) guidelines. CR was defined as no circulating blasts or extramedullary disease, no lymphadenopathy, splenomegaly, skin/gum infiltration/testicular mass/central nervous system involvement, trilineage hematopoiesis and less than 5 percentage blasts, absolute neutrophil count (ANC) greater than 1000 per micro liter, platelets less than 100 000 per micro liter, no recurrence for 4 weeks. CRi meet all criteria for complete response except platelet count and/or ANC.
Baseline until disease progression or death (maximum duration: 12.1 weeks)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Duration of Response (DOR)
Time Frame: Baseline until disease progression or death (maximum duration: 12.1 weeks)
DOR defined as time (in days) from date of first response until date of first documented progressive disease (PD) or death (from any cause), whichever came first. Progressive disease as per NCCN guidelines was defined as increase of at least 25 percentage (%) in the absolute number of circulating or bone marrow blasts or development of extramedullary disease.
Baseline until disease progression or death (maximum duration: 12.1 weeks)
Progression Free Survival (PFS)
Time Frame: Baseline until disease progression or death (maximum duration: 12.1 weeks)
PFS was defined as the time interval (in days) from the date of first study drug administration to the date of first observation of PD or death due to any cause, whichever came first. PD as per NCCN guidelines was defined as increase of at least 25% in the absolute number of circulating or bone marrow blasts or development of extramedullary disease.
Baseline until disease progression or death (maximum duration: 12.1 weeks)
Overall Survival (OS)
Time Frame: Baseline until death (maximum duration: 12.1 weeks)
Overall Survival was defined as the time interval from the date of first study drug administration to the date of death due to any cause.
Baseline until death (maximum duration: 12.1 weeks)
Number of Participants With Minimal Residual Disease (MRD)
Time Frame: Baseline until death or study cut-off (maximum duration: 12.1 weeks)
Presence of MRD was measured by sequencing and/or flow cytometry in participants achieving CR and CRi. CR was defined as no circulating blasts or extramedullary disease, no lymphadenopathy, splenomegaly, skin/gum infiltration/testicular mass/central nervous system involvement, trilineage hematopoiesis and less than 5 percentage blasts, ANC greater than 1000 per micro liter, platelets less than 100 000 per micro liter, no recurrence for 4 weeks. Complete response with incomplete blood count recovery meet all criteria for complete response except platelet count and/or ANC.
Baseline until death or study cut-off (maximum duration: 12.1 weeks)
