Pembrolizumab/Vibostolimab (MK-7684A) or Atezolizumab in Combination With Chemotherapy in First Line Treatment of Extensive-Stage Small Cell Lung Cancer (MK-7684A-008/KEYVIBE-008) (NCT05224141)

A Phase 3, Randomized, Double-Blind Study of MK-7684A in Combination With Etoposide and Platinum Followed by MK-7684A vs Atezolizumab in Combination With Etoposide and Platinum Followed by Atezolizumab for the First-Line Treatment of Participants With Extensive-Stage Small Cell Lung Cancer (KEYVIBE-008)

🔵 Active, Not Recruiting Phase3 💊 Investigational Drug / Biologic Sponsor: Merck Sharp & Dohme LLC

🩺 Plain-English Summary (8th-Grade Level)

This study will evaluate the combination of a fixed dose pembrolizumab/vibostolimab co-formulation (MK-7684A) with etoposide/platinum chemotherapy followed by MK-7684A compared to the combination of atezolizumab with etoposide/platinum chemotherapy followed by atezolizumab in the first-line treatment of Extensive-Stage Small Cell Lung Cancer (ES-SCLC). The primary hypothesis is, with respect to overall survival, MK-7684A in combination with the background therapy of etoposide/platinum followed by MK-7684A, is superior to atezolizumab in combination with the background therapy of etoposide/platinum followed by atezolizumab.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (7 items) and avoid the listed exclusions (19 items).
