Brief Summary

This is a phase 3, randomized, double-blind study of adjuvant calderasib plus subcutaneous pembrolizumab and berahyaluronidase alfa (MK-3475A) versus adjuvant placebo plus MK-3475a in participants with completely resected stage IIA-IIIB (N2), KRAS G12C-mutant non-small cell lung cancer following receipt of either neoadjuvant pembrolizumab plus chemotherapy or adjuvant chemotherapy. The primary goal of the study is to compare adjuvant calderasib plus MK-3475A to adjuvant placebo plus MK-3475A with respect to disease-free survival (DFS) as assessed by the investigator.

Conditions

Non-small Cell Lung Cancer

• Disease-free Survival (DFS)

  DFS is the time from randomization to any recurrence (local, locoregional, regional, or distant), occurrence of new primary NSCLC, or death due to any cause, whichever occurs first.

Secondary Outcomes (11)

• Overall Survival (OS)

  Up to ~11 years

• Distant Metastasis-Free Survival (DMFS)

  Up to ~11 years

• Change from Baseline in the European Organization for Research and Treatment of Cancer (EORTC)-Quality of Life Questionnaire-Core 30 (QLQ-C30) Global Health Status (Item 29) and Quality of Life (Item 30) Combined Score

  Up to ~11 years

• Change from Baseline in the EORTC-QLQ-C30 Physical Functioning (Items 1-5) Combined Score

  Up to ~11 years
