This is a single center, phase Ib/II study combining an anti-PD-1 antibody and an anti-CTLA-4 antibody with IL-15. It is testing the hypothesis that the addition of nogapendekin alfa inbakicept to nivolumab and ipilimumab will augment the clinical activity of those two drugs.
Interventions
DRUG
Ipilimumab
Ipilimumab will be given intravenously at a dose of 1mg/kg.
DRUG
Nivolumab
Nivolumab will be given intravenously at a dose of 360mg.
DRUG
Nogapendekin alfa inbakicept
Nogapendekin alfa inbakicept will be given subcutaneously at the assigned dose level.
Primary outcome measures
Progression-free survival (PFS) (Phase Ib acceptable dose participants and Phase II participants)
Time frame: Start of treatment through 2 years after end of treatment (up to 4 years)
PFS is defined as the duration of time from the start date of study treatment to the date of earliest progression or death, whichever occurs first. Patients who neither progress nor die by the data cutoff date will be censored at the last follow up date.
Incidence of dose-limiting toxicities (DLTs) (Phase Ib participants)
Time frame: From start of treatment through completion of cycle 1 (each cycle is 42 days)
DLTs are defined in the protocol.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Histologically or cytologically confirmed, previously untreated or recurrent metastatic NSCLC.
- Availability of archival biopsy tissue or willingness to undergo a biopsy prior to C1D1 for biomarker analysis, including PD-L1 by IHC using a CLIA-certified test. Results of the PD-L1 testing are not required for enrollment.
- Measurable disease per RECIST 1.1.
- At least 18 years of age.
- ECOG performance status ≤ 1
- Adequate organ and marrow function, as defined below:
- Absolute neutrophil count ≥ 1.5 K/cumm
- Platelets ≥ 100 K/cumm
- Hemoglobin ≥ 9.0 g/dL
- AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN without hepatic metastasis and ≤ 5 x IULN with hepatic metastasis
- Total bilirubin ≤ 2 x IULN (except participants with Gilbert's syndrome who must have total bilirubin \< 3.0 mg/dL)
- Creatinine clearance \> 30 mL/min by Cockcroft-Gault
- INR ≤ 1.5 unless using therapeutic anticoagulation
- PTT/aPTT \< 1.5 x IULN unless using therapeutic anticoagulation
- Patients with brain metastases are eligible if they have previously treated with surgery or radiation therapy, are neurologically stable after a washout period of at least 2 weeks, and are not receiving corticosteroids at dose higher than 10 mg of prednisone or equivalent on C1D1.
- The effects of the treatment regimen on the developing human fetus are unknown. For this reason, people of childbearing potential and people able to father a child must agree to use highly effective methods of contraception, according to the protocol, from the time of consent through 6 months after the last dose of study treatment.
- Ability to understand and willingness to sign an 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
- ROS1 fusion
- NTRK fusion
- MET Exon14 skipping mutation
- BRAF V600E mutation
- Use of any live vaccines within 28 days of C1D1.
- Prior chemotherapy 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 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 if not on effective anti-retroviral therapy with undetectable viral load for 6 months. Patients with HIV who are receiving anti-retroviral therapy and have had an undetectable viral load for at least 6 months are eligible. 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. People of childbearing potential must have a negative pregnancy test within 7 days of study entry.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
