Blinatumomab and Pembrolizumab for Adults With Relapsed/Refractory B-cell Acute Lymphoblastic Leukemia With High Marrow Lymphoblasts

About

Brief Summary

This is a Phase I/II study of blinatumomab in combination with pembrolizumab in adult patients with relapsed or refractory B-lineage ALL The primary objective of this study is to determine if the addition of pembrolizumab to blinatumomab improves the overall response rate (CR+ CRh) relative to blinatumomab alone in adult subjects with relapsed or refractory B-cell acute lymphoblastic leukemia with high bone marrow lymphoblast percentage (>50% lymphoblasts).
