According to a release, Pfizer will join Exact Sciences’ sales representatives in reaching both physicians and health systems and also will actively participate in extending and deepening the Cologuard marketing campaign.

“This partnership marks a turning point in the fight to end colorectal cancer,” Exact Sciences CEO Kevin Conroy said in a statement. “Together we can help reduce the prevalence of colorectal cancer by combining the power of Cologuard and the talented Exact Sciences team with Pfizer’s experience, relationships and resources.”

The co-promotion efforts will begin in the fourth quarter of 2018.
