Merck, known as MSD outside the United States and Canada, announced that the US Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to KEYTRUDA (pembrolizumab), the company's anti-PD-1 therapy, for the treatment of patients with microsatellite instability high (MSI-H) metastatic colorectal cancer.

KEYTRUDA is a humanized monoclonal antibody that works by increasing the ability of the body's immune system to help detect and fight tumor cells.

It blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

"We are committed to understanding the full potential of KEYTRUDA to help patients with a broad range of difficult-to-treat cancers," said Dr Roger M Perlmutter, president, Merck Research Laboratories. "The data investigating the use of KEYTRUDA in patients with advanced colorectal cancer whose tumors have substantial evidence of mismatch DNA repair defects have been encouraging, and we appreciate the opportunity that this FDA Breakthrough Therapy Designation provides us to accelerate our effort to bring KEYTRUDA to these patients."

The FDA's Breakthrough Therapy Designation is intended to expedite the development and review of a candidate that is planned for use, alone or in combination, to treat a serious or life-threatening disease or condition when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints.
