Public criteria

Who may be able to participate

The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.

Requirements people may need to meetInclusion criteria
  • The target population includes adults with small lung nodules that may represent a new diagnosis of lung cancer, who typically would be managed by CT surveillance in usual clinical practice. Thus, we will enroll all patients:
  • aged ≥35 years
  • at least one nodule measuring ≤15 mm in average diameter on chest CT.
Reasons someone may not be able to joinExclusion criteria
  • Pregnant Women
  • Age \<35 years
  • Known diagnosis of cancer (except non-melanoma skin cancer) within 5 years

Important: This is the sponsor’s public criteria, not a determination of eligibility. The study team must review your individual situation.
