GENETIC TESTING

FDA Watch: Expanded Label Clearance Opens Cologuard to a Younger Market

September was an eventful month for one of the hottest products on the consumer genetic test market, the Cologuard multi-target stool DNA test (mtSDNA) for colorectal cancer screening produced by Exact Sciences. The month started badly with the release of a CMS-sponsored research report finding Cologuard “less effective and considerably more costly” than alternatives. Although Exact Sciences quickly criticized the report and its analytical methodology, its stock took a beating.

But on Sept. 23, less than three weeks later, things turned around when Exact Sciences announced that the FDA had widened its approval for Cologuard to include people age 45 and older, as opposed to the previous approval for people age 50 and older. The clearance, which came a year before the company expected, adds 19 million potential users to Cologuard’s target market. It also greatly improves the prospects for a U.S. Preventive Services Task Force (USPSTF) thumbs-up on mtSDNA colorectal cancer screening. The USPSTF decision is expected by the end of the year.
