Phase I Study of Adoptive Immunotherapy With Enriched and Expanded Autologous Natural Killer (NK) Cells for Patients With Ph+ Acute Lymphoblastic Leukemia (ALL)

"Each patient will receive repeated intravenous (IV) infusions of escalating doses of expanded autologous NK cells.~The initial dose will be 1 x 106/kg of recipient body weight (BW), followed by half log increments of the dose level for each infusion, to a maximum of 1 x 108/kg of recipient BW or until they experience any toxicity, for a maximum of 5 infusions. The minimum interval between each infusion will be 28 days. No conditioning therapies will be administered before the infusion of the expanded NK cells. Patients may receive TKI maintenance."
