First-Line Ipilimumab Plus Nivolumab and Nogapendekin Alfa Inbakicept (N-803) in Patients With Stage IV or Recurrent Non-Small Cell Lung Cancer

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.

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.

  • 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.

Primary outcomes

  1. 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.

  2. 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.

Secondary outcomes

  1. Adverse event effect rate (All participants)

    Time frame: Start of treatment through 100 days after discontinuation of therapy (up to 2 years and 100 days)

    Defined as the number of study treatment related adverse events (AEs) and discontinuations due to treatment-related AEs. Adverse events will be assessed using the CTCAE v5.0 criteria.

  2. Disease control rate (DCR) (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)

    DCR is defined as the proportion of patients achieving either a complete response (CR), partial response (PR), or stable disease (SD), according to RECIST 1.1.

    Complete Response (CR): Disappearance of all target lesions. Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (<10 mm short axis).

    Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

    Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum diameters while on study.

  3. Duration of response (DoR) (Phase Ib acceptable dose participants and Phase II participants) (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)

    DoR is defined as the time from the confirmation of a CR of PR according to RECIST 1.1 until the first date that recurrent or progressive disease is objectively documented or death from any cause.

    Complete Response (CR): Disappearance of all target lesions. Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (<10 mm short axis).

    Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

  4. Objective response rate (ORR) (Phase Ib acceptable dose participants and Phase II participants)

    Time frame: Start of treatment through completion of treatment or progression (up to 2 years)

    ORR is defined as the proportion of patients achieving CR or PR measured according to RECIST 1.1.

    Complete Response (CR): Disappearance of all target lesions. Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (<10 mm short axis).

    Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

  5. Immune-related best overall response (iBOR) (Phase Ib acceptable dose participants and Phase II participants)

    Time frame: Start of study treatment to up to 2 years after the end of treatment (up to 4 years)

    iBOR is defined as the proportion of the best confirmed immune-related response recorded from the start of the study treatment until disease progression, the end of treatment, or death, whichever comes first, according to iRECIST guideline.

  6. Immune-related progression-free survival (iPFS) (Phase Ib acceptable dose participants and Phase II participants)

    Time frame: Start of study treatment up to 2 years after treatment is completed (up to 4 years)

    iPFS is defined as the time from the start date of study treatment to date of confirmed immune-related progressive disease by investigator's assessment or death from any cause, whichever occurs first.

    Immune unconfirmed progressive disease (iUPD) is defined according to iRECIST guidelines.

  7. Overall survival (OS) (Phase Ib acceptable dose participants and Phase II participants)

    Time frame: Start of study treatment up to 2 years after treatment is completed (total 4 years)

    OS is defined as the duration of time from the start date of study treatment to death from any cause.
