Cohort A: Experimental ArmEXPERIMENTAL3-week cycles. N803, Tislelizumab, and Docetaxel will be administered on Cycle 1 and 2. N803 and Tislelizumab will be administered on Cycle 3 and onward until end of study.
Cohort A: Control ArmACTIVE_COMPARATORThe control arm treatment regimen will consist of repeated 3-week cycles with a ± 3-day window for each visit of Docetaxel 75 mg/m2 IV.
Cohort B: Experimental ArmEXPERIMENTAL3-week cycles. N803, prior failed checkpoint inhibitor, and Docetaxel will be administered on Cycle 1 and 2. N803 and prior failed checkpoint inhibitor will be administered on Cycle 3 and onward until end of study.
Cohort B: Control ArmACTIVE_COMPARATORThe control arm treatment regimen will consist of repeated 3-week cycles with a ± 3-day window for each visit of Docetaxel 75 mg/m2 IV.

Healthy SubjectsEXPERIMENTALSubjects will be scheduled for first apheresis collection on study Day 1. All subjects will receive N-803 at a fixed dose of 1 mg by subcutaneous (SC) injection 4 to 5 days prior to the second apheresis collection. The study day for N-803 administration will be determined based on the planned date of the second apheresis collection.
