Novel therapies for pediatric acute lymphoblastic leukemia.

PURPOSE OF REVIEW: This review summarizes the current novel therapy landscape in pediatric acute lymphoblastic leukemia (ALL), with a focus on key clinical trials which will shape the future direction of care for these children. RECENT FINDINGS: Recent landmark immunotherapy trials in B-ALL have demonstrated significant benefit for children, adolescents, and young adults with relapsed/refractory high-risk leukemia. Due to these successes, current trials are asking the question as to whether immunotherapy can be successfully incorporated upfront. Additionally, therapies targeting novel antigens or molecular pathways are being developed, providing new options for children previously thought to have incurable leukemia. SUMMARY: As survival for ALL has relatively plateaued with maximizing intensity through conventional chemotherapy, continued preclinical and clinical study of novel immunotherapeutic and targeted agents is crucial to further improve outcomes in childhood leukemia.
