Trial Summary

What is the purpose of this trial?

The purpose of this study is to assess the efficacy and safety of pembrolizumab in combination with concurrent chemoradiation therapy followed by either pembrolizumab with olaparib placebo (Arm 1) or with olaparib (Arm 2) compared to concurrent chemoradiation therapy followed by durvalumab (Arm 3) in participants with unresectable, locally advanced NSCLC. Arms 1 and 2 will be studied in a double-blind design and Arm 3 will be open-label. The primary hypotheses are: 1. Pembrolizumab with concurrent chemoradiation therapy followed by pembrolizumab with olaparib is superior to concurrent chemoradiation therapy followed by durvalumab with respect to progression-free survival (PFS) and overall survival (OS) 2. Pembrolizumab with concurrent chemoradiation therapy followed by pembrolizumab is superior to concurrent chemoradiation therapy followed by durvalumab with respect to PFS and OS

Interventions

  • Carboplatin (Platinum-based Chemotherapy)
  • Cisplatin (Platinum-based Chemotherapy)
  • Durvalumab (Checkpoint Inhibitor)
  • Etoposide (Topoisomerase Inhibitor)
  • Olaparib (PARP Inhibitor)
  • Paclitaxel (Taxane Chemotherapy)
  • Pembrolizumab (Checkpoint Inhibitor)
  • Pemetrexed (Antimetabolite Chemotherapy)
  • Placebo for Olaparib (Placebo)
  • Thoracic Radiotherapy (Radiation)
Trial OverviewThe study tests pembrolizumab combined with chemoradiation followed by either pembrolizumab plus olaparib placebo or just olaparib versus chemoradiation followed by durvalumab. It aims to see if the first two methods are better than the third in improving survival without cancer progression.

Group I: pembrolizumab+chemoradiation→pembrolizumab+olaparib placeboExperimental Treatment8 Interventions
Participants will receive pembrolizumab 200 mg intravenously (IV) every 3 weeks (Q3W) in combination with 3 cycles of the investigator's choice of platinum doublet chemotherapy and concurrent standard thoracic radiotherapy (60 Gray (Gy) over 6 weeks) followed by pembrolizumab plus olaparib placebo twice a day (BID) for approximately 1 year.
Group II: pembrolizumab+chemoradiation→pembrolizumab+olaparibExperimental Treatment8 Interventions
Participants will receive pembrolizumab 200 mg IV Q3W in combination with 3 cycles of the investigator's choice of platinum doublet chemotherapy and concurrent standard thoracic radiotherapy (60 Gy over 6 weeks) followed by pembrolizumab plus olaparib 300 mg BID for approximately 1 year.
Group III: chemoradiation→durvalumabActive Control7 Interventions
Participants will receive 3 cycles of the investigator's choice of platinum doublet chemotherapy with concurrent standard thoracic radiotherapy (60 Gy over 6 weeks) followed by durvalumab 10 mg/kg every 2 weeks (Q2W) for approximately 1 year.
