- People with non-squamous NSCLC for whom a doctor-approved targeted therapy is not considered suitable
- People who are able to provide a tumor tissue sample — either one stored from within the last 5 years (or since completing their last treatment), or a newly collected biopsy taken from an area not previously treated with radiation, within 90 days before starting the trial treatment
- People who have not yet received any systemic (whole-body) treatment for their advanced/metastatic NSCLC
- People who are able to complete all required pre-trial check-ups within 35 days (Part A) or 28 days (Part B) of beginning the screening process
Who may not be able to join:
- People who have been diagnosed with small cell lung cancer
- People who have an immune system deficiency, or who have been taking steroid medications above a certain daily dose, or any other immune-suppressing medication in the 7 days before the first trial treatment
- People who have another cancer (in addition to NSCLC) that is currently growing or has required active treatment within the past 2 years
- People who have active cancer spread to the brain or spinal fluid lining (confirm with trial site)
- People who have an autoimmune disease that has needed systemic (whole-body) treatment within the past 2 years
- People who have a history of lung inflammation (not caused by infection) that required steroid treatment, or who currently have lung inflammation
- People who have an active infection that requires systemic (whole-body) treatment
- People with serious heart conditions, including unstable chest pain, a heart attack within the past 6 months, or severe heart failure

- People who have had major surgery within 3 weeks before the first trial treatment
- People who are expected to need another form of cancer treatment during the trial
- People who have a bowel condition (such as Crohn's disease or ulcerative colitis), significantly impaired liver function, or another condition that a doctor believes could interfere with how oral medications are absorbed or processed
- People receiving chemotherapy who have active diverticulitis, an abscess in the abdomen, a bowel blockage, or cancer spread throughout the abdominal cavity
- People who already have moderate or worse nerve damage (neuropathy)
- People who have previously received systemic chemotherapy, targeted therapy, or biological cancer treatment for their metastatic disease
- People who are unwilling or unable to take folic acid or vitamin B12 supplements, if they are assigned to receive a chemotherapy drug called pemetrexed
- People with a known allergy or sensitivity to carboplatin, paclitaxel, pemetrexed, or any of their ingredients

- People who have received a live vaccine within 30 days before the first trial treatment — approved COVID-19 mRNA, adenoviral, or inactivated vaccines are permitted, but investigational (unapproved) vaccines are not
- People who have previously received immunotherapy and had to stop it due to a severe or worse immune-related side effect
- People who have had chemotherapy or biological cancer therapy within 4 weeks before the first trial treatment, or whose side effects from earlier cancer treatment have not sufficiently resolved
- People who are currently taking part in, or have taken part in, another clinical trial involving an experimental treatment or device within the past 4 weeks
