EC Approves Merck’s KEYTRUDA (pembrolizumab) as Adjuvant Therapy for Certain Patients With Renal Cell Carcinoma (RCC) Following Surgery

Merck, known as MSD outside the United States and Canada, announced that the European Commission has approved KEYTRUDA, Merck’s anti-PD-1 therapy, as monotherapy for the adjuvant treatment of adults with renal cell carcinoma (RCC) at increased risk of recurrence following nephrectomy, or following nephrectomy and resection of metastatic lesions. This approval is based on results from the Phase 3 KEYNOTE-564 trial, in which KEYTRUDA demonstrated a statistically significant improvement in disease-free survival (DFS), reducing the risk of disease recurrence or death by 32% (HR=0.68 [95% CI, 0.53-0.87]; p=0.0010) after a median follow-up of 23.9 months compared to placebo, in patients at increased risk of recurrence (defined in the clinical trial protocol as intermediate-high or high risk following nephrectomy and those with resected advanced disease).

“KEYTRUDA addresses a critical unmet need for treatment options that help patients reduce their risk of cancer returning following surgery,” said Dr. Thomas Powles, professor of Genitourinary Oncology and director of Barts Cancer Centre at St. Bartholomew’s Hospital. “The European Commission’s approval of KEYTRUDA brings certain patients with renal cell carcinoma a long-awaited therapy that has demonstrated a statistically significant reduction in the risk of disease recurrence or death by almost a third.”

“KEYTRUDA is the first adjuvant therapy approved for certain patients with renal cell carcinoma in Europe, providing the option of immunotherapy earlier in the course of their treatment,” said Dr. Scot Ebbinghaus, vice president, clinical research, Merck Research Laboratories. “This approval demonstrates our progress in bringing KEYTRUDA to patients with earlier stages of cancer, with the goal of helping more patients around the globe prevent disease recurrence.”

This approval allows marketing of KEYTRUDA monotherapy in all 27 European Union member states plus Iceland, Lichtenstein, Norway and Northern Ireland.

Merck has a broad clinical development program exploring KEYTRUDA, as monotherapy or in combination, as well as several other investigational and approved medicines across multiple settings and stages of RCC, including adjuvant and advanced or metastatic disease.
