Magrolimab in Children and Adults With Recurrent or Progressive Malignant Brain Tumors

Summary

Children and adults with recurrent or progressive malignant brain tumors have a dismal prognosis, and outcomes remain very poor. Magrolimab is a first-in-class anticancer therapeutic agent targeting the Cluster of differentiation 47 (CD47)-signal receptor protein-alpha (SIRP-alpha) axis. Binding of magrolimab to human CD47 on target malignant cells blocks the "don't eat me" signal to macrophages and enhances tumor cell phagocytosis. Pre-clinical studies have shown that treatment with magrolimab leads to prolonged survival in models of Atypical Teratoid Rhabdoid Tumors (ATRT), diffuse intrinsic pontine glioma (DIPG), high-grade glioma (adult and pediatric), medulloblastoma, and embryonal tumors formerly called Primitive Neuro-Ectodermal Tumors (PNET). Safety studies in humans have proven that magrolimab has an excellent safety profile. Ongoing studies are currently testing magrolimab in adult myelodysplastic syndromes, acute myeloid leukemia, non-Hodgkin lymphoma, colorectal, ovarian, and bladder cancers. Herein we propose to test the safety of magrolimab in children and adults with recurrent or progressive malignant brain tumors.
