Pembro + Blina Combination in Pediatric and Young Adult Patients With Relapsed/Refractory Acute Leukemia or Lymphoma
Withdrawn before enrolling · Phase 1
Conditions studied: Leukemia, B-cell, Lymphoma, B-Cell
In brief
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.
