Pembro + Blina Combination in Pediatric and Young Adult Patients With Relapsed/Refractory Acute Leukemia or Lymphoma

March 30, 2021 updated by: Children's Hospital Medical Center, Cincinnati

A Pilot Study of Blinatumomab in Combination With a PD1 Inhibitor, Pembrolizumab, in Pediatric and Young Adult Patients With Relapsed/Refractory CD19 Positive B-cell Acute Leukemia or Lymphoma

This study combines the immune checkpoint inhibitor pembrolizumab with the BITE antibody blinatumomab for the treatment of relapsed/refractory pre-B cell ALL. Pembrolizumab at the proposed dosing schedule has been very well tolerated in adult studies, including elderly and unfit patients, as well as in pediatric patients. Both blinatumomab and pembrolizumab are FDA-approved for use in children as well as adults. Phase I/II trials in adult patients have demonstrated safety and activity of pembrolizumab in combination with multiple agents. In this trial, the combination of pembrolizumab and blinatumomab will be investigated for toxicity as well as possible synergy in the treatment of relapsed/refractory pre-B cell ALL.

This is a single institution investigator-initiated pilot study designed to test the safety and feasibility of combining pembrolizumab and blinatumomab immunotherapies in children, adolescents, and young adults with CD19 positive hematologic malignancies. The investigator will define the toxicity profile of the combination in two safety strata based on whether or not a patient has had a prior allogeneic hematopoietic stem cell transplant (HSCT), as they hypothesize that the immune toxicities may differ between strata. In addition, the overall response rate (CR/CRh) to this therapy will be estimated. Additional biologic correlates will be conducted to delineate the effect of the combination therapy on the patient's leukemia/lymphoma and T-cell populations and how this may influence response to therapy.

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

Participants who meet study eligibility will receive or continue to receive blinatumomab by continuous IV infusion for 28 days and also receive pembrolizumab (by IV infusion over 30 minutes) on day 12 of cycle 1 and day 5 of cycle 2.

One cycle lasts 35 days and patients will receive 2 cycles of therapy.

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.
Interventional

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
