Interventions
N-803 will be administered at the following doses intravenously: 0.3/0.5, 1.0, 3.0, 6.0 ug/kg N-803 will be administered at the following does subcutaneously: 6.0, 10.0, 15.0, 20.0 ug/kg N-803 will be administered intratumorally at a dose of 10.0 ug/kg, followed by N-803 administered subcutaneously at a dose of 15.0 ug/kg. Each treatment cycle consists of 4 weeks on therapy and 2 weeks off. Patients will receive weekly dose of ALT-803 for 4 weeks (Days 1, 8, 15, and 22) used for the identification of the OBD and MTD. After a 2-week rest period (Weeks 5 and 6) and recovery of any dose limiting toxicities to grade 0-1 of Cycle 1, a second 6-week cycle (4 weeks on treatment and 2 weeks off) can begin. After a rest period during Weeks 5 and 6 of Cycle 2, stable or benefitting patients assessed at week 8 +/- 1 may receive up to 2 additional 6-week cycles.
