Brief Summary:
This is a Phase IIb, multicohort, open-label multicenter study of combination immunotherapies in patients who have previously received treatment with PD-1/PD-L1 immune checkpoint inhibitors. All patients in Cohorts 1-4 will receive the combination treatment of PD-1/PD-L1 checkpoint inhibitor plus N-803 for up to 17 cycles. Each cycle is six weeks in duration. Some patients who experience disease progression while on study in Cohorts 1-4 may roll over into Cohort 5 and receive combination therapy with a PD-1/PD-L1 checkpoint inhibitor, N-803, and PD-L1 t-haNK cellular therapy for up to an additional 17 cycles. Each cycle is six weeks in duration. All patients will receive N-803 once every 3 weeks. Patients will also receive the same checkpoint inhibitor that they received during their previous therapy. Radiologic evaluation will occur at the end of each treatment cycle. Treatment will continue for up to 2 years, or until the patient experiences confirmed progressive disease or unacceptable toxicity, withdraws consent, or if the Investigator feels it is no longer in the patient's best interest to continue treatment. Patients will be followed for disease progression, post-therapies, and survival through 24 months past administration of the first dose of study drug.
