This is an open label, multicenter, phase I study of adoptive immunotherapy with enriched and expanded autologous natural killer (NK) cells for patients with Ph+ acute lymphoblastic leukemia (ALL) in complete hematologic remission (CHR) but with persistent/recurrent minimal residual disease (MRD) ≥60 years or not eligible for other post-CHR treatment modalities. The study will investigate the safety and tolerability of a new type of NK-based immunotherapy based on the infusion of escalating doses of ex-vivo expanded autologous NK cells in Ph+ ALL patients. A maximum of 6 patients will be enrolled in two different steps. No conditioning therapies will be administered before the infusion of the expanded NK cells. Patients may receive tyrosine kinase inhibitor (TKI) maintenance.
