Moxetumomab Pasudotox (CAT-8015, HA22) in Children With B-lineage Acute Lymphoblastic Leukemia and Minimal Residual Disease Prior to Allogeneic Hematopoietic Stem Cell Transplantation

Summary

This is a phase II, open-label, nonrandomized, prospective study to evaluate the activity, safety, and feasibility of administration of moxetumomab pasudotox in the pre-allogeneic hematopoietic cell transplantation (HCT) setting to patients with B-lineage Acute Lymphoblastic Leukemia (ALL) who are in a morphologic complete remission and have pre-transplant minimal residual disease (MRD) \> 0.01% (detected by flow cytometry). The primary objective of this study is to determine if treatment with moxetumomab pasudotox in the MRD positive setting is able to lead to MRD negativity (\< 0.01% by flow cytometry) or at least a 1-log10 reduction in MRD prior to allogeneic HCT.
