Agents with novel mechanisms of action distinct from available ATP-competitive tyrosine kinase inhibitors have been tested in patients with previously treated, Philadelphia chromosome–positive chronic myeloid leukemia and offer promise to facilitate deeper remissions.
During a debate, Nicholas J. Short, MD, argued that intensive chemotherapy combined with a BCR-ABL tyrosine kinase inhibitor still holds the place of standard-of-care treatment for Phildelphia chromosome acute lymphoblastic leukemia, while Sabina Chiaretti, MD, PhD, made the case for targeted therapy.
On the treatment of adult patients with acute lymphoblastic leukemia, long-term cure rates in elderly populations, or those older than 55 to 60 years of age, are approximately 15% to 20% and represent a clinically unmet need in this hematologic cancer.
Using a modified pediatric regimen to treat adolescents and young adults with acute lymphoblastic leukemia led to superior outcomes compared with historical adult ALL regimen results, according to a retrospective analysis that evaluated 95 AYAs aged 14 to 39 years. Findings were presented at the eighth annual Society of Hematologic Oncology virtual meeting.
In the past 5 years, 3 new treatment options have emerged to treat patients with relapsed or refractory acute lymphoblastic leukemia, providing hope for patients with this disease, but also raising clinical questions of how to choose among these agents and what is the best option for the patient at which time.
In an interview with Targeted Oncology Guillermo Garcia-Manero, MD, discussed the key findings from the QUAZAR AML-001 study and the importance of the FDA approval of CC-486 in post-remission acute myeloid leukemia.
The FDA granted approval to the oral hypomethylating agent, CC-486 (azacitidine tablets, Onureg), as a maintenance treatment for adult patients with acute myeloid leukemia who achieved a first complete remission or with incomplete blood count recovery after intensive induction chemotherapy and who are unable to complete intensive curative therapy.
The primary end point of statistically superiority in major molecular response rate at 24 weeks was met with asciminib versus bosutinib as treatment of patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase in the phase 3 ASCEMBL study.
