Blinatumomab in Pediatric B-cell Acute Lymphoblastic Leukemia (ALL) With Minimal Residual Disease (MRD)

February 20, 2022 updated by: Seoul National University Hospital

Blinatumomab for Minimal Residual Disease Before Hematopoietic Stem Cell Transplantation With Pediatric B-cell Precursor Acute Lymphoblastic Leukemia

This is a single-arm, open-label, multi-center phase I study using blinatumomab for pediatric B-cell acute lymphoblastic leukemia patients with positive of minimal residual disease. 1 Cycle of blinatumomab treatment followed by hematopoietic stem cell transplantation. Blinatumomab has approved to treat adults and children with B-cell precursor ALL who are in remission but still have MRD. However, data on the effects and safety of blinatumomab in children with B-precursor ALL with MRD positive are insufficient.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

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
Safety evaluation including cytokine release syndrome
Time Frame: At the latest possible timepoint prior to the initiation of transplant conditioning or after 30 days of Blinatumomab treatment
The incidence of treatment-emergent and treatment-related adverse events
At the latest possible timepoint prior to the initiation of transplant conditioning or after 30 days of Blinatumomab treatment

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.
