A Phase III, Randomized, Multi-Center, Open-Label, Comparative Global Study to Determine the Efficacy of Durvalumab or Durvalumab and Tremelimumab in Combination With Platinum-Based Chemotherapy for First-Line Treatment in Patients With Metastatic Non Small-Cell Lung Cancer (NSCLC) (POSEIDON)

AstraZeneca·interventional·Posted May 23, 2017·Updated Mar 13, 2026

In Brief

A Phase 3 clinical trial evaluating Durvalumab, Tremelimumab, and 5 other interventions for Non Small Cell Lung Cancer NSCLC. Active but no longer recruiting, targeting 1,186 participants across 175 sites in 19 countries.

Detailed Summary

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.

Interventions

Durvalumabdrug

IV infusions every 3 weeks for 12 weeks (4 cycles) and every 4 weeks thereafter until disease progression or other discontinuation criteria

Tremelimumabdrug

IV infusions every 3 weeks for 12 weeks (4 cycles). An additional dose of tremelimumab will be administered in the week 16.

Abraxane + carboplatindrug

Standard of care chemotherapy (squamous and non-squamous patients): Abraxane 100 mg/m2 on Days 1, 8, and 15 of each 21-day cycle. Carboplatin Area under the plasma drug concentration-time curve (AUC) 5 or 6 via IV infusion on Day 1 of each 21-day cycle for 4 to 6 cycles (ie, 4 cycles for Treatment Arms 1 and 2 and 4 to 6 cycles for Treatment Arm 3).

Gemcitabine + cisplatindrug

Standard of care chemotherapy (squamous patients only): Gemcitabine 1000 or 1250 mg/m2 via IV infusion on Days 1 and 8 of each 21-day cycle + cisplatin 75 mg/m2 via IV infusion on Day 1 of each 21-day cycle, for 4 to 6 cycles (ie, 4 cycles for Treatment Arms 1 and 2 and 4 to 6 cycles for Treatment Arm 3).

Gemcitabine + carboplatindrug

Standard of care chemotherapy (squamous patients only): Gemcitabine 1000 or 1250 mg/m2 via IV infusion on Days 1 and 8 of each 21-day cycle + carboplatin AUC 5 or 6 via IV infusion on Day 1 of each 21-day cycle for 4 to 6 cycles (ie, 4 cycles for Treatment Arms 1 and 2 and 4 to 6 cycles for Treatment Arm 3).

Pemetrexed + carboplatindrug

Standard of care chemotherapy (non-squamous patients only): Pemetrexed 500 mg/m2 and carboplatin AUC 5 or 6 via IV infusion on Day 1 of each 21-day cycle for 4 to 6 cycles (ie, 4 cycles for Treatment Arms 1 and 2 and 4 to 6 cycles for Treatment Arm 3); then continue pemetrexed 500 mg/m2 maintenance \[i.e., q4w for Treatment Arms 1 and 2. For Treatment Arm 3, Pemetrexed maintenance therapy can be given either q3w or q4w (dependent on Investigator decision and local standards)\] until objective disease progression.

Pemetrexed + cisplatindrug

Standard of care chemotherapy (non-squamous patients only): Pemetrexed 500 mg/m2 and cisplatin 75 mg/m2 via IV infusion on Day 1 of each 21-day cycle, for 4 to 6 cycles (ie, 4 cycles for Treatment Arms 1 and 2 and 4 to 6 cycles for Treatment Arm 3); then continue pemetrexed 500 mg/m2 maintenance \[i.e., q4w for Treatment Arms 1 and 2. For Treatment Arm 3, Pemetrexed maintenance therapy can be given either q3w or q4w (dependent on Investigator decision and local standards)\] until objective disease progression.
