Ponatinib inhibits LCK and PI3K signaling and promotes CD8(+) T stem cell memory cell development

Repurposing a leukemia drug to strengthen CAR-T cell persistence could enhance immunotherapy outcomes for cancer patients.

Researchers discovered that ponatinib, a CML drug, promotes the formation of long-lived T stem cell memory cells by inhibiting LCK and PI3K pathways, and dramatically improves CAR-T cell persistence and antitumor activity. This repurposing approach could enhance adoptive cell therapy outcomes.

Why it surfaced

Highly novel mechanism for enhancing CAR-T therapy using an existing approved drug; limited by preclinical-only evidence but strong translational potential.
