Management of Recurrent Acute Lymphoblastic Leukemia With T-Cell Engagement: CAR T, BiTEs, and Beyond.

Immunotherapies targeting CD19 (blinatumomab) and CD22 (inotuzumab ozogamicin) have demonstrated higher complete response rates and improved survival compared with chemotherapy in relapsed/refractory acute lymphoblastic leukemia (ALL), and are now standard of care in the relapsed setting. However, most adult patients still die of ALL despite these therapies, with or without hematopoietic stem cell transplant. At the NCCN 2019 Annual Congress: Hematologic Malignancies, Dr. Jae Park summarized clinical data from key trials of novel immunotherapies in ALL and reviewed evidence-based treatment approaches for adults with relapsed/refractory B-cell ALL.
