Galleri in the Medicare Population

This multi-center comparative, prospective, cohort study is designed to assess the real world clinical impact, including safety and test performance, of Galleri^®, a blood-based multi-cancer early detection (MCED) test. The study will seek enrollment representative of the Medicare population, including people traditionally not represented in clinical research.

The study will enroll approximately 50,000 participants aged 50 and older with Medicare coverage who will receive Galleri in addition to usual care as well as a passively-enrolled contemporaneous comparator cohort of approximately 50,000 Medicare beneficiaries who receive usual care without MCED screening.
