Official title: A Phase 3, Randomized, Double-blind, Placebo- and Active-Comparator-Controlled Study of MK-1084 Plus Durvalumab Versus Placebo Plus Durvalumab in Participants With Locally Advanced, Unresected KRAS G12C-Mutant Non-Small Cell Lung Cancer Without Disease Progression Following Definitive Platinum-Based Chemoradiotherapy (KANDLELIT-015)

Run by Merck Sharp & Dohme LLC · NCT07554339 · Data updated 2026-11-12

This trial tests whether calderasib plus durvalumab can help people with locally advanced KRAS G12C NSCLC who have completed chemotherapy and radiation, compared with placebo plus durvalumab.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with locally advanced, unresected Stage II to III NSCLC (nonsquamous) with KRAS G12C who completed definitive chemoradiotherapy and have adequate tumor tissue for biomarker testing.

Probably not a fit

Patients whose cancer does not respond to the combination or who experience unacceptable toxicity may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 3 interventional study in locally advanced, unresected NSCLC with KRAS G12C mutation. Participants have completed platinum-based chemoradiotherapy and will receive calderasib with durvalumab or placebo with durvalumab to see if the cancer stays under control longer. The study uses central testing of tumor samples for KRAS G12C and PD-L1, along with biomarker research. If eligible, participants must have stable HIV on ART or managed HBV/HCV as applicable. Primary goals focus on progression-free survival and overall survival.

Why it matters

Potential benefit: If successful, the combination could extend the time patients live without disease progression and possibly improve overall survival.

How similar studies have gone: Previous approaches in targeted KRAS G12C and immunotherapy combinations have shown signals of activity but results are still being established in this setting.
