Study of Durvalumab + Tremelimumab With Chemotherapy or Durvalumab With Chemotherapy or Chemotherapy Alone for Patients With Lung Cancer (POSEIDON).

Non-Small Cell Lung CancerLymphomaSarcomaPhase 3Stage IIIStage IVEGFRALKPD-L1

This is a randomized, open-label, multi-center, global, Phase III study to determine the efficacy and safety of durvalumab + tremelimumab combination therapy + Standard of care (SoC) chemotherapy or durvalumab monotherapy + SoC chemotherapy versus SoC chemotherapy alone as first line treatment in patients with metastatic non small-cell lung cancer (NSCLC) with tumors that lack activating epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) fusions.

Conditions: Non Small Cell Lung Cancer NSCLC

Eligibility Criteria

Inclusion Criteria

  • For inclusion in the study, patients should fulfill the following criteria:
  • Aged at least 18 years.
  • Histologically or cytologically documented Stage IV NSCLC.
  • Confirmed tumor PD-L1 status prior to randomization.
  • Patients must have tumors that lack activating EGFR mutations and ALK fusions.
  • No prior chemotherapy or any other systemic therapy for metastatic NSCLC.
  • World Health Organization (WHO)/Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • No prior exposure to immunemediated therapy, excluding therapeutic anticancer vaccines.

Exclusion Criteria

  • Mixed small-cell lung cancer and NSCLC histology, sarcomatoid variant.
  • Active or prior documented autoimmune or inflammatory disorders.
  • Brain metastases or spinal cord compression unless the patient's condition is stable and off steroids.
  • Active infection including tuberculosis, hepatitis B, hepatitis C, or human immunodeficiency virus.
