Detailed Description

The investigator is testing the ability of a biologically active therapy in blinatumomab, an anti-CD19/CD3 bispecific T-cell engager, to further reduce residual leukemia immediately prior to HCT to improve post-HCT outcomes. This Phase 2 study will determine the effectiveness of delivering 1 to 2 cycles of blinatumomab (Days 1-28) as bridging therapy in children, adolescent and young adults with relapse or persistent MRD B-ALL. Eligible subjects will receive 1 or 2, 28-day cycles of blinatumomab prior to proceeding to HCT. Centralized MRD assessment will be performed after completion of the 28-days of blinatumomab using both flow cytometry (University of Washington, Brent Wood, MD) and High-Throughput Deep Sequencing (HTS) MRD technologies (Adaptive Technologies, Seattle, WA). Subjects who achieve flow cytometry negative MRD (<0.01%) after a single cycle of blinatumomab can proceed directly to HCT whereas subjects who remain MRD positive by flow cytometry may receive a 2nd cycle of blinatumomab. Subjects who remain MRD positive by flow cytometry after a 2nd cycle of blinatumomab will come off study.

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.

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

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.

Sexually active men must agree to use barrier contraceptive for the duration of treatment and for 2 months after the last dose of chemotherapy.

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 Subjects in Complete Remission (CR)
Time Frame: 1 or 2 Months depending on the number of cycles of blinatumomab
The primary efficacy variable is the percent of subjects that remain in Complete Remission (CR) after completion of 1 or 2 cycles of blinatumomab. Complete remission was defined as <5% blasts in the bone marrow. Complete remission was further defined as minimal residual disease (MRD) positive (>/= to 0.01%) or MRD negative (<0.01%) as measured by flow cytometry of the bone marrow.
1 or 2 Months depending on the number of cycles of blinatumomab
Percentage of Subjects Flow Cytometry (FC) -Minimal Residual Disease (MRD) Negative Defined as <0.01% Leukemia
Time Frame: 1 to 2 Months depending on the number of cycles of blinatumomab
The primary efficacy variable is the percent of subjects that become Flow Cytometry-MRD negative (FC-MRD negative) < 0.01% after completion of 1 or 2 cycles of blinatumomab.
1 to 2 Months depending on the number of cycles of blinatumomab

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
Percentage of Subjects That Are High-Throughput Deep Sequencing (HTS)-Minimal Residual Disease (MRD) Negative Defined as Undetectable
Time Frame: After completion of Blinatumomab bridging therapy (1 participant's course consisted of 1 cycle, the other participant's course consisted of 2 cycles)
The percent of subjects that achieve MRD negative by molecular High-Throughput Deep Sequencing (HTS-MRD negative) (MRD undetectable) after completion of Blinatumomab bridging therapy, which may consist of 1 to 2 cycles of Blinatumomab.
After completion of Blinatumomab bridging therapy (1 participant's course consisted of 1 cycle, the other participant's course consisted of 2 cycles)
