Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This is a prospective, observational study of 1,000 subjects with known or suspected cancer and 2,000 subjects with no known cancer. Potential participants will be asked questions to confirm their eligibility by a nurse navigator, study staff member, or physician. Informed consent will be carried out for eligible subjects in accordance with applicable federal regulations and International Council for Harmonisation (ICH)/Good Clinical Practice (GCP) guidelines. Subjects will then complete a survey, and study staff will draw 60 mL of blood and measure the height and weight of the subject. Where available, data from the medical records of the cancer subjects will reviewed and collected. In addition, non-cancer subjects will be requested to allow access to their medical records as an optional portion of their informed consent.
