Stopped: Revisions to eligibility/design being made prior to enrollment of first participants.
Background: Surgery is the primary treatment for non-small cell lung cancer (NSCLC) that is diagnosed in its earlier stages. But the tumors often return. Radiation and chemotherapy can improve survival in some people who have had surgery for NSCLC, but these treatments also cause serious side effects. A new approach, called immunotherapy, may be a better way to stop NSCLC tumors from coming back. Objective: To test a new treatment (H1299 lung cancer cell vaccine combined with the drug N-803) in people who received surgery for NSCLC. Eligibility: Adults aged 18 years or older with no sign of disease after surgery for NSCLC. Design: Participants will be screened. They will have a physical exam with blood tests. They will have tests of their heart and lung function. They will have imaging scans. Study treatment will be given in 28-day cycles. Participants will visit the clinic on the first day of each cycle. They will receive 2 treatments at each visit: The study vaccine is given as 2-4 small shots under the skin of the thigh or arm. N-803 is given as a shot under the skin of the abdomen. Treatment will continue for 6 cycles. Blood tests and imaging scans will be repeated throughout the study. Participants will have a blood test 1 month after receiving the 6th vaccine. Some participants may then resume taking N-803; they may also receive 2 more vaccinations at 3 and 6 months after their previous treatment. Follow-up visits will continue for up to 5 years.

Phase II Component: To assess the frequency of immunologic responses to purified CT-X and autosomal CT antigens in NSCLC participants following vaccinations with H1299 cancer cell lysate and Montanide ISA-51 VG adjuvant in combination with N-803
Timeframe: 1 month following first 6 vaccinations, and every 6 months during retreatment
Phase I Component: To determine the safety of H1299 lung cancer cell lysate vaccines administered with Montanide (Registered Trademark) ISA-51 VG adjuvant and N-803
Timeframe: before each cycle, every 2 weeks between vaccines 1 & 2 (AE only), at each treatment evaluation, and at the safety visit
