About

The primary objective of this study is to compare the effect of zimberelimab (ZIM) and domvanalimab (DOM) in combination with chemotherapy relative to pembrolizumab (PEMBRO) in combination with chemotherapy on progression-free survival (PFS) and overall survival (OS) in patients with untreated metastatic non-small cell lung cancer with no actionable genomic alteration.

Inclusion and exclusion criteria

Key Inclusion Criteria:

  • Life expectancy ≥ 3 months.

  • Pathologically documented NSCLC that meets both of the criteria below:

    • Have documented evidence of Stage IV NSCLC disease at the time of enrollment (based on American Joint Committee on Cancer (AJCC), Eighth Edition).
    • Have documented negative test results for epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) mutations.
  • Have no actionable genomic alterations such as ROS proto-oncogene 1 (ROS1), neurotrophic tyrosine receptor kinase (NTRK), proto-oncogene B-raf (BRAF), RET mutations, or other driver oncogenes with approved frontline therapies.

  • Have not received prior systemic treatment for metastatic NSCLC.

  • Measurable disease per RECIST v1.1 criteria by investigator assessment.

  • Eastern Cooperative Oncology Group performance status (ECOG PS) score of 0 or 1.

  • Have adequate organ functions.

Key Exclusion Criteria:

  • Have mixed small-cell lung cancer (SCLC) and NSCLC histology.
  • Positive serum pregnancy test or individuals who are breastfeeding or have plans to breastfeed during the study period.
  • Received prior treatment with any anti-PD-1, anti-PD-L1, or any other antibody targeting an immune checkpoint.
  • Known hypersensitivity to the study drug, its metabolites, or formulation excipient.
  • Have an active second malignancy or have had an active second malignancy within 3 years prior to enrollment.
  • Have an active autoimmune disease that required systemic treatment in past 2 years (i.e., with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs).
  • Are receiving chronic systemic steroids.
  • Have significant third-space fluid retention.
  • Have untreated central nervous system (CNS) metastases and/or carcinomatous meningitis.
  • Active chronic inflammatory bowel disease (ulcerative colitis, Crohn's disease) or gastrointestinal perforation within 6 months of enrollment.
  • Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
  • Has had an allogenic tissue/solid organ transplant.
  • Have received a live-virus vaccination within 30 days of planned treatment start. Seasonal flu and COVID-19 vaccines that do not contain live virus are permitted.
  • Have known active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

792 participants in 3 patient groups

Zimberelimab (ZIM) +Domvanalimab (DOM) + Chemotherapy
Experimental group
Description:
Participants will receive ZIM 360 mg + DOM 1200 mg (up to 35 doses) with chemotherapy every 3 weeks (Q3W) on Day 1 of each 21-day cycle. Choice of chemotherapy is dependent on histology. * Participants with nonsquamous histology will receive cisplatin 75 mg/m\^2 or carboplatin area under the concentration versus time curve (AUC)5 + pemetrexed 500 mg/m\^2 Q3W for first 4 cycles. After the completion of the first 4 cycles, participants with nonsquamous histology may continue with maintenance pemetrexed 500 mg/m\^2 Q3W until disease progression or intolerable toxicities. * Participants with squamous histology will receive carboplatin AUC 6 Q3W with paclitaxel 200 mg/m\^2 Q3W or nab-paclitaxel 100 mg/m\^2 weekly (QW) for first 4 cycles.
Treatment:
Drug: Pemetrexed
Drug: Zimberelimab
Drug: Cisplatin
Drug: Carboplatin
Drug: Paclitaxel
Drug: Nab-paclitaxel
Drug: Domvanalimab
Pembrolizumab (PEMBRO) + Chemotherapy
Active Comparator group
Description:
Participants will receive PEMBRO 200 mg (up to 35 doses) with chemotherapy Q3W on Day 1 of each 21-day cycle. Choice of chemotherapy is dependent on histology. * Participants with nonsquamous histology will receive cisplatin 75 mg/m\^2 or carboplatin AUC 5 + pemetrexed 500 mg/m\^2 Q3W for first 4 cycles. After the completion of the first 4 cycles, participants with nonsquamous histology may continue with maintenance pemetrexed 500 mg/m\^2 Q3W until disease progression or intolerable toxicities. * Participants with squamous histology will receive carboplatin AUC 6 Q3W with paclitaxel 200 mg/m\^2 Q3W or nab-paclitaxel 100 mg/m\^2 weekly (QW) for first 4 cycles.
Treatment:
Drug: Pemetrexed
