---|---|
Experimental: Non-Small cell Lung Cancer
Nivolumab, intravenously (given by vein), once every 3 weeks Ipilimumab, intravenously (given by vein), once every 6 weeks Participants will have blood samples taken for cell free deoxyribonucleic acid (cfDNA) testing. If there is an increasing or stable tumor cfDNA, platinum-doublet chemotherapy will be given. |
Diagnostic Test: cfDNA blood test
Blood sample will be taken for cfDNA testing Drug: Nivolumab Antineoplastic agent Drug: Ipilimumab Antineoplastic agent Combination Product: Platinum-based Chemotherapy May include carboplatin with gemcitabine, or paclitaxel or pemetrexed |
- Percentage of participants whose disease does not worsen (progression-free survival rate) at 6 months [ Time Frame: 6 months ]
- Average percentage of tumor cfDNA detected in the blood (tumor cfDNA clearance rate) at 3 weeks [ Time Frame: 3 weeks ]
- Average percentage of tumor cfDNA detected in the blood (tumor cfDNA clearance rate) at 12 weeks [ Time Frame: 12 weeks ]
- Number participants with adverse events [ Time Frame: 4 years ]

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Age ≥ 18 years at the time of screening or age of consent.
- Written informed consent obtained from the subject prior to performing any protocol-related procedures, including screening evaluations.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Weight ≥ 35 kg.
- Must have a life expectancy of at least 12 weeks.
- Recurrent or newly diagnosed metastatic non-small cell lung cancer
- Tumor PDL1 status <50%.
- Non-Squamous and squamous histologies are eligible
- Histologies with targetable mutations are not eligible, regardless of prior treatment with tyrosine kinase inhibitors
- No prior radiation, surgery or chemotherapy is allowed for the current diagnosis of non-small cell lung cancer
- Adequate organ and marrow function
Exclusion Criteria:
- Receipt of any conventional or investigational anticancer therapy within 21 days or palliative radiotherapy within 14 days prior to the scheduled first dose of study treatment.
- Prior receipt of any immune-mediated therapy.
- Incomplete surgical resection
- Concurrent enrolment in another therapeutic clinical study. Enrolment in observational studies will be allowed.
- Any toxicity (excluding alopecia) from prior standard therapy that has not been completely resolved to baseline at the time of consent.
- Participants with prior history of myocardial infarction, transient ischemic attack, congestive heart failure ≥ Class 3 based on New York Heart Association Functional Classification or stroke within the past 3 months prior to the scheduled first dose of study treatment.
- Active or prior documented autoimmune disorders within the past 3 years prior to the scheduled first dose of study treatment with exceptions.
- Participants with confirmed human immunodeficiency virus (even if viral load is undetectable), chronic or active hepatitis B or C, or active hepatitis A.
- History of primary immunodeficiency, solid organ transplantation, or active tuberculosis (by clinical evaluation that includes clinical history, physical examination and radiographic findings, and tuberculosis testing in line with local practice).
- Other invasive malignancy within 2 years. Non-invasive malignancies (i.e., cervical carcinoma in situ, in situ prostate cancer, non-melanomatous carcinoma of the skin, ductal carcinoma in situ of the breast that has been surgically cured) are excluded from this definition.
- Known allergy or hypersensitivity to investigational product formulations.
- History of more than one event of infusion related reactions requiring permanent discontinuation of intravenous drug treatment.
- Uncontrolled intercurrent illness including, but not limited to ongoing or active infection requiring antibiotic therapy, uncontrolled hypertension, bleeding diatheses, or psychiatric illness/social situations that would limit compliance with study requirements, substantially increase risk of incurring adverse events, or compromise the ability of the subject to give written informed consent.
- Current or prior use of immunosuppressive medication within 14 days prior to the scheduled first dose of study treatment with exceptions.
- Receipt of live, attenuated vaccine within 30 days prior to the scheduled first dose of study treatment - Major surgery within 28 days prior to scheduled first dose of study treatment or still recovering from prior surgery.
- Females who are pregnant, lactating, or intend to become pregnant during their participation in the study.
- Participants who are involuntarily incarcerated or are unable to willingly provide consent or are unable to comply with the protocol procedures.
- Any condition that, in the opinion of the investigator, would interfere with safe administration or evaluation of the investigational products or interpretation of subject safety or study results.
