Merck announced that the FDA has approved KEYTRUDA, Merck’s anti-PD-1 therapy, for the adjuvant treatment of patients with renal cell carcinoma (RCC) at intermediate-high or high risk of recurrence following nephrectomy, or following nephrectomy and resection of metastatic lesions. The approval is based on data from the pivotal 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) compared to placebo. Median DFS has not been reached for either group.
“Despite decades of research, limited adjuvant treatment options have been available for earlier-stage renal cell carcinoma patients who are often at risk for recurrence. In KEYNOTE-564, pembrolizumab reduced the risk of disease recurrence or death by 32%, providing a promising new treatment option for certain patients at intermediate-high or high risk of recurrence,” said Dr. Toni K. Choueiri, director, Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute, and professor of medicine, Harvard Medical School. “With this FDA approval, pembrolizumab may address a critical unmet treatment need and has the potential to become a new standard of care in the adjuvant setting for appropriately selected patients.”
Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue and can affect more than one body system simultaneously. Immune-mediated adverse reactions can occur at any time during or after treatment with KEYTRUDA, including pneumonitis, colitis, hepatitis, endocrinopathies, nephritis, dermatologic reactions, solid organ transplant rejection, and complications of allogeneic hematopoietic stem cell transplantation. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions. Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of KEYTRUDA. Based on the severity of the adverse reaction, KEYTRUDA should be withheld or permanently discontinued and corticosteroids administered if appropriate. KEYTRUDA can also cause severe or life-threatening infusion-related reactions. Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman.
