A Study to Investigate the Efficacy of Durvalumab Plus Tremelimumab in Combination With Chemotherapy Compared With Pembrolizumab in Combination With Chemotherapy in Metastatic NSCLC Patients With Non-squamous Histology Who Have Mutations and/or Co-mutations in STK11, KEAP1, or KRAS

Exclusion Criteria38

• Any evidence of acute or uncontrolled diseases or history of allogeneic organ transplant.
• Mixed small cell lung cancer and NSCLC histology.
• Major surgical procedure within 28 days prior to the first dose of the study intervention or an anticipated need for major surgery during the study.
• Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease \[eg, colitis or Crohn's disease\], systemic lupus erythematosus, sarcoidosis, granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis \[requiring immunosuppressive systemic therapy, eg, methotrexate, steroids\], hypophysitis, uveitis, etc), autoimmune pneumonitis and autoimmune myocarditis. The following are exceptions to this criterion:
• Participants with vitiligo or alopecia.
• Participants with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement.
• Any chronic skin condition that does not require systemic therapy.
• Participants without active disease in the last 5 years may be included but only after consultation with the Study Clinical Lead.
• Participants with celiac disease controlled by diet alone.
• Medical contraindication to platinum-based doublet chemotherapy.
• History of another primary malignancy except:
• Malignancy treated with curative intent with no known active disease ≥ 2 years before the first dose of study intervention and of low potential risk for recurrence
• Adequately resected non-melanoma skin cancer and curatively treated in situ disease.
• Persistent toxicities (Common Terminology Criteria for Adverse Events \[CTCAE\] Grade ≥ 2) caused by previous anti-cancer therapy, alopecia and vitiligo are excluded toxicities.
• Participants with Grade ≤ 2 neuropathy can be considered based on Investigator's judgement. Participants with irreversible toxicity that is not reasonably expected to be exacerbated by treatment with study intervention in the opinion of the Investigator may be included (eg, hearing loss).
• Spinal cord compression unless asymptomatic and stable.
• Participant meets the following:
• \- Symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia (multifocal premature ventricular contractions, bigeminy, trigeminy, ventricular tachycardia), which requires treatment (CTCAE Grade 3), symptomatic or uncontrolled atrial fibrillation despite treatment, or asymptomatic sustained ventricular tachycardia. Participants with atrial fibrillation controlled by medication or arrhythmias controlled by pacemakers may be permitted based on the Investigator judgement with cardiologist consultation recommended.
• Any concurrent chemotherapy, investigational product, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (eg, hormone replacement therapy) is acceptable.
• No radiation therapy is allowed, unless it is 1) definitive radiation that had been administered at least 6 months prior, 2) palliative radiation to brain, with associated criteria for stability or lack of symptoms, or 3) palliative radiation to painful bony lesions (this must comprise less than 30% of the bone marrow)
• Patients with suspected brain metastases at screening should have an IV contrast-enhanced MRI (preferred) or IV contrast-enhanced CT/CT-PET of the brain prior to study entry. If brain metastases are detected patients must be treated before randomization. Randomization is only permitted if patients with brain metastases have:
• Confirmed stable condition
• Returned neurologically to baseline Brain metastases will not be recorded as RECIST target lesions at baseline.
• History of leptomeningeal carcinomatosis.
• Known to have tested positive for active tuberculosis infection
• Known active hepatitis infection, positive HCV antibody, HBsAg, or anti-HBc, at screening. Participants with a past or resolved HBV infection (defined as the presence of anti-HBc and absence of HBsAg) are eligible. Participants positive for HCV antibody are eligible only if PCR is negative for HCV RNA. Participants co-infected with HBV and HCV, or co-infected with HBV and HDV, namely: HBV positive (presence of HBsAg and/or anti-HBcAb with detectable HBV DNA); AND
• HCV positive (presence of anti-HCV antibodies); OR
• HDV positive (presence of anti-HDV antibodies).
• Known human immunodeficiency virus (HIV) infection that is not well controlled.
• Current or prior use of immunosuppressive medication within 14 days before the first dose of study intervention. The following are exceptions to this criterion:
• Intranasal, inhaled, topical steroids or local steroid injections (eg, intra-articular injection).
• Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent.
• Steroids as premedication for hypersensitivity reactions (eg, CT scan premedication, premedication for chemotherapy) or a single dose for palliative purpose (eg, pain control).
• Receipt of live attenuated vaccine within 30 days prior to the first dose of study intervention.
• Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or the follow-up period of an interventional study.
• Participants with a known hypersensitivity to any of the study interventions or any of the excipients of the products.
• For females only: Currently pregnant (confirmed with positive pregnancy test) or breastfeeding, or who are planning to become pregnant.
• Female participants should refrain from breastfeeding from enrolment throughout the study and until up to 14 months after the last dose of cisplatin or 180 days after pemetrexed or 90 days after tremelimumab or durvalumab or pembrolizumab, whichever is longer; and during treatment with carboplatin.
