Study of Pembrolizumab With Concurrent Chemoradiation Therapy Followed by Pembrolizumab With or Without Olaparib in Stage III Non-Small Cell Lung Cancer (NSCLC) (MK-7339-012/KEYLYNK-012) (NCT04380636)

A Phase 3 Study of Pembrolizumab (MK-3475) in Combination With Concurrent Chemoradiation Therapy Followed by Pembrolizumab With or Without Olaparib vs Concurrent Chemoradiation Therapy Followed by Durvalumab in Participants With Unresectable, Locally Advanced, Stage III Non-Small Cell Lung Cancer (NSCLC)

๐Ÿ”ต Active, Not Recruiting Phase3 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Merck Sharp & Dohme LLC

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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
