Phase 1 Study of Locoregional Injections of Ex Vivo Expanded Natural Killer Cells

Description

A cycle is 28 days (4 weeks) consisting of weekly infusions of UD TGFβi NK cells via Ommaya or a programable ventriculoperitoneal (VP) shunt for three weeks followed by one week of rest. The dose-limiting toxicity (DLT) period is the first 28 days (4 weeks). A DLT is defined as any event that is at least possibly attributable to the TGFβi NK cell product and that occurs from the time of initial NK cell infusion through the end of the first cycle (28 days). Patients with stable or improved disease will receive up to 12 cycles of TGFβi NK cell infusions.
