Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Subject has KRasG12C mutation in tumor tissue or other bio-specimens containing cancer cells or DNA. Historical, local laboratory result (up to 5 years prior to this study) can be used for Phase 1 subjects. Phase 2 subjects must be tested for KRasG12C mutation by a central laboratory.
  • Subject has tumor type requirement as follows: advanced or metastatic solid tumors including NSCLC and CRC.
