Merck receives Breakthrough Therapy Designation from FDA for KEYTRUDA (pembrolizumab) in advanced colorectal cancer
Co announces that the 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. This is the third Breakthrough Therapy Designation granted for KEYTRUDA. Merck is conducting a Phase 2 registration study (KEYNOTE-164) to evaluate the efficacy and safety of KEYTRUDA based on microsatellite instability status in patients with previously treated advanced colorectal cancers, and is also planning a Phase 3 study (KEYNOTE-177) in a treatment naïve patient population. Registration-enabling trials of KEYTRUDA are currently enrolling patients in melanoma, NSCLC, head and neck cancer, bladder cancer, gastric cancer, colorectal cancer, esophageal cancer, breast cancer, Hodgkin lymphoma, multiple myeloma and other tumors, with further trials in planning for other cancers.
