A phase 1 trial of venetoclax in combination with liposomal vincristine in patients with relapsed or refractory B‐cell or T‐cell acute lymphoblastic leukemia: Results from the ECOG‐ACRIN EA9152 protocol

Relapsed or refractory (r/r) acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LL) remains a therapeutic challenge. Preclinical data in both B- and T-ALL suggests synergy of venetoclax (VEN) with vincristine (VCR). We designed a phase I/II trial (EA9152) of the combination of L-VCR and VEN for patients with r/r B-or T-cell ALL or LL. Here, we report the safety and efficacy outcomes of the phase I portion of this trial (NCT03504644).
