“Patients with advanced RCC whose cancer progresses following immune checkpoint and anti-angiogenic therapies face a poorer prognosis, and for those patients, there is a crucial unmet need for new options with an alternative mechanism of action,” said Dr. Marjorie Green, senior vice president and head of late-stage oncology, global clinical development, Merck Research Laboratories. “The FDA’s priority review designation of this application reinforces the urgency to provide new options to previously treated patients with advanced RCC, and we are committed to working closely with the FDA to bring WELIREG to these patients as quickly as possible.”
