What this study is about

Researchers are testing whether adding inotuzumab ozogamicin to standard chemotherapy improves outcomes for patients with high-risk B-cell Acute Lymphoblastic Leukemia (B-ALL), mixed phenotype acute leukemia, and B-lymphoblastic lymphoma. The trial also compares outcomes of patients treated with or without inotuzumab ozogamicin.
