Later-Stage HumanInvestigationalNot addressed

Important context

Trial eligibility (participation has strict criteria): Clinical-trial participation has study-specific eligibility criteria; registry listing does not mean a person qualifies or should enroll.

What changed: ClinicalTrials.gov lists MK-3475A±Calderasib (MK-1084) in Completely Resected Stage IIA-IIIB (N2) KRAS G12Cm NSCLC (MK-1084-013) (NCT07431827) as a Phase 3 interventional cancer study. The registry status is Recruiting, with the record last updated 2026-08-17.

Study snapshot: Phase 3; Recruiting; planned enrollment 400. Conditions listed: Non-small Cell Lung Cancer. A primary outcome listed by the registry is: Disease-free Survival (DFS).

This entry tracks verified trial-registry facts. Trial registration by itself does not show that an intervention is effective, safe for a particular person, FDA-approved for this use, or recommended by clinical guidelines.

What This Means

ClinicalTrials.gov confirms that this Phase 3 study is registered and currently listed as Recruiting. This establishes the study's existence and registry-reported design/status, not a treatment benefit.

What This Doesn't Mean

A registered trial is not proof that the intervention works, is not FDA approval for this cancer or use, and is not a clinical-guideline recommendation.

Why It Matters

Phase 3 trials can contribute later-stage human evidence. CancerDiscoveries can track this record as results and regulatory information emerge.

Promise & Proof

Proof — strength of the evidence 4 / 5

Base score from evidence stage: Later-Stage Human.

Promise — potential significance if later evidence holds up 3 / 5

Baseline — a validly-evidenced story starts here; every further point below is an explicit, checkable reason.
The record includes substantive editorial reasoning about why this discovery matters.
Targets a cancer type with historically limited effective treatment options.

These two ratings are automatically computed from this story's own structured evidence fields and are shown separately on purpose — they are never combined into one score. They describe this record, not a medical recommendation: they do not establish medical certainty, do not substitute for reading the cited sources, and are recalculated whenever the underlying evidence changes.

Population / Applicability

Studied in: Participants age 18 Years and older with Non-small Cell Lung Cancer who meet the study-specific registry eligibility criteria. (Adults)

Eligibility is study-specific. Registry information does not determine whether any individual should enroll in or receive the intervention.
