Ipilimumab plus Nivolumab and Nogapendekin Alfa Inbakicept for the Treatment of Stage IV or Recurrent Non-small Cell Lung Cancer, FLINN Trial
This phase I/II trial studies the side effects and best dose of nogapendekin alfa inbakicept (N-803) in combination with nivolumab and ipilimumab, and to see how well the combination works in treating patients with non-small cell lung cancer (NSCLC) that is stage IV or that has come back after a period of improvement (recurrent). N-803 is a protein that has been shown to stimulate the immune system and improve response to immunotherapies. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Adding N-803 to nivolumab and ipilimumab may be a safe and effective treatment for patients with stage IV or recurrent NSCLC.

- The effects of the treatment regimen on the developing human fetus are unknown. For this reason, women of childbearing potential and people able to father a child must agree to use highly effective methods of contraception from the time of consent through 6 months after the last dose of study treatment
- Ability to understand and willingness to sign an institutional review board (IRB)-approved written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants
Exclusion Criteria
- Mixed histology (including small cell lung cancer)
- Tumor harboring any of the following: * classic EGFR mutations * HER2 mutation * ALK fusion * ROS1 fusion * RET fusion * NTRK fusion * MET Exon14 skipping mutation * BRAF V600E mutation
- Use of any live vaccines within 28 days of C1D1
- Prior systemic therapy in the adjuvant setting or during concurrent radiation therapy for locally advanced disease within 12 months prior to enrollment. If the interval from the last treatment is 12 months or longer, the patient is eligible
- Radiation therapy within 14 days prior to C1D1
- History of major surgery within 14 days prior to C1D1
- Underlying medical conditions that, in the Investigator’s opinion, will make the administration of study treatment hazardous, including but not limited to: * History of interstitial lung disease or noninfectious pneumonitis, * Active viral, bacterial or fungal infections requiring parenteral treatment within 14 days of C1D1, * Clinically significant cardiovascular disease, * A condition that may obscure the interpretation of toxicity determination or adverse events (AEs), * History of prior solid-organ transplantation
- Concurrent medical condition requiring the use of supra-physiologic doses of corticosteroids (> 10 mg/day of oral prednisone or equivalent) or immunosuppressive medications (absorbable topical corticosteroids are not excluded)
- HIV-infected patients unless with undetectable viral load for at least 6 months prior to starting the study. HIV testing not required in the absence of known history of infection
- Evidence of chronic hepatitis B (HBV) that is detectable on suppressive therapy. Patients with evidence of chronic HBV infection with undetectable HBV viral load on suppressive therapy are eligible. HBV testing not required in the absence of known history of infection
- History of hepatitis C virus (HCV) infection that has not been cured or that has a detectable viral load. Patients with a history of HCV that has been treated and cured are eligible. Patients with HCV infection who are currently on treatment and have an undetectable HCV viral load are eligible. HCV testing not required in the absence of known history of infection
- Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
- Any active autoimmune disease or a documented history of autoimmune disease or syndrome that required systemic treatment in the past 2 years (i.e., with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs), except for vitiligo or resolved childhood asthma/atopy * Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment * Participants with asthma who require intermittent use of bronchodilators, inhaled corticosteroids, or local corticosteroid injections will not be excluded from this study * Participants on chronic systemic corticosteroids will be excluded from the study
- Prior or concurrent malignancy whose natural history has the potential to interfere with the safety or efficacy assessment of the investigational regimen. Patients with prior or concurrent malignancy that does NOT meet that definition are eligible for this trial
- Use of other investigational drugs (drugs not marketed for any indication) within 28 days or 5 half-lives (whichever is longer) of C1D1
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to any agents used in the study, or known hypersensitivity to recombinant proteins, or any excipient contained in the trial formulations
- Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 7 days of study entry

PRIMARY OBJECTIVES:
I. To determine the dose-limiting toxicities (DLTs) of the combination of nivolumab and ipilimumab with nogapendekin alfa inbakicept. (Phase Ib)
II. To determine progression-free survival of patients with stage IV or recurrent NSCLC who are treated with nivolumab, ipilimumab, and nogapendekin alfa inbakicept. (Phase Ib acceptable dose and Phase II)
SECONDARY OBJECTIVES:
I. To evaluate the safety and tolerability of the combination of nivolumab, ipilimumab, and nogapendekin alfa inbakicept. (All Patients)
II. To determine the efficacy of the combination of nivolumab, ipilimumab, and nogapendekin alfa inbakicept in patients with previously untreated or recurrent stage IV NSCLC. (Phase Ib acceptable dose and Phase II)
EXPLORATORY OBJECTIVES:
I. To explore the relationship of the immunophenotype of peripheral blood immune cells and response to combined therapy. (All Patients)
II. To explore the changes in tumor immune cell infiltrate after treatment and relationship with response. (All Patients)
OUTLINE:
Patients receive nogapendekin alfa inbakicept (N-803) subcutaneously (SC) on days 1 and 22 of each cycle, nivolumab intravenously (IV) over 30 minutes on days 1 and 22 of each cycle, and ipilimumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 42 days for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then continue receiving N-803 SC and nivolumab IV on days 1 and 22 of each cycle thereafter. Cycles repeat every 42 days for up to 2 years (including previous 4 cycles) in the absence of disease progression or unacceptable toxicity. Patients also undergo biopsy during screening and computed tomography (CT), magnetic resonance imaging (MRI), and blood sample collection throughout the study. Patients may also undergo an optional biopsy on study.
After completion of study treatment, patients are followed every 3 months for 2 years or until death, whichever occurs first.
