FDA Grants Priority Review to Merck?s Supplemental Biologics License Application for KEYTRUDA? (pembrolizumab) as Adjuvant Therapy in Certain Patients With Renal Cell Carcinoma (RCC) Followin
KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced that the U.S. Food and Drug Administration (FDA) has accepted and granted priority review for a new supplemental Biologics License Application (sBLA) for 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 (surgical removal of a kidney), or following nephrectomy and resection of metastatic lesions. This sBLA is based on data from the pivotal Phase 3 KEYNOTE-564 trial, in which KEYTRUDA demonstrated a statistically significant and clinically meaningful improvement in disease-free survival (DFS) compared to placebo. These data were presented at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting. The FDA has set a Prescription Drug User Fee Act (PDUFA), or target action, date of December 10, 2021.
?The acceptance of our application demonstrates the progress we are making in earlier lines and earlier stages of certain cancers across our oncology portfolio,? said Dr. Scot Ebbinghaus, vice president, clinical research, Merck Research Laboratories. ?We look forward to working with the FDA towards the goal of bringing the first adjuvant immunotherapy option to appropriate patients with renal cell carcinoma in the U.S.?
KEYTRUDA is currently approved in the U.S., Europe and Japan in combination with axitinib for the first-line treatment of patients with advanced RCC. Merck is continuing to study KEYTRUDA, in combination or as monotherapy, as well as other investigational products across multiple settings and stages of RCC, including adjuvant and advanced or metastatic disease. The broad clinical development program exploring KEYTRUDA in RCC includes over 20 clinical studies and more than 4,000 patients worldwide.
About KEYNOTE-564
KEYNOTE-564 is a randomized, double-blind, Phase 3 trial (ClinicalTrials.gov,?NCT03142334) evaluating KEYTRUDA monotherapy for the adjuvant treatment of patients with RCC who have undergone nephrectomy and who have intermediate-high risk, high risk, or M1 no evidence of disease (M1 NED) RCC with clear cell component. The study enrolled 994 patients who were randomized to receive either KEYTRUDA (200 mg intravenously [IV] on Day 1 of each three-week cycle for up to 17 cycles) or placebo (saline solution IV on Day 1 of each three-week cycle for up to 17 cycles). The primary endpoint is DFS, and the secondary endpoints include overall survival and safety.
About Renal Cell Carcinoma (RCC)
Renal cell carcinoma is by far the most common type of kidney cancer; about nine out of 10 kidney cancer diagnoses are RCCs. Renal cell carcinoma is about twice as common in men as in women. Most cases of RCC are discovered incidentally during imaging tests for other abdominal diseases. Worldwide, it is estimated there were more than 431,000 new cases of kidney cancer diagnosed and more than 179,000 deaths from the disease in 2020. In the U.S., it is estimated there will be more than 76,000 new cases of kidney cancer diagnosed and almost 14,000 deaths from the disease in 2021.
About KEYTRUDA??(pembrolizumab) Injection, 100 mg
KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body?s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that 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.
Merck has the industry?s largest immuno-oncology clinical research program. There are currently more than 1,500 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.
Selected KEYTRUDA??(pembrolizumab) Indications in the U.S.
Melanoma
KEYTRUDA is indicated for the treatment of patients with unresectable or metastatic melanoma.
KEYTRUDA is indicated for the adjuvant treatment of patients with melanoma with involvement of lymph node(s) following complete resection.
Non-Small Cell Lung Cancer
KEYTRUDA, in combination with pemetrexed and platinum chemotherapy, is indicated for the first-line treatment of patients with metastatic nonsquamous non-small cell lung cancer (NSCLC), with no EGFR or ALK genomic tumor aberrations.
KEYTRUDA, in combination with carboplatin and either paclitaxel or paclitaxel protein-bound, is indicated for the first-line treatment of patients with metastatic squamous NSCLC.
KEYTRUDA, as a single agent, is indicated for the first-line treatment of patients with NSCLC expressing PD-L1 [tumor proportion score (TPS) =1%] as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations, and is:
- stage III where patients are not candidates for surgical resection or definitive chemoradiation, or
- metastatic.
- in combination with platinum- and fluoropyrimidine-based chemotherapy, or
- as a single agent after one or more prior lines of systemic therapy for patients with tumors of squamous cell histology that express PD-L1 (CPS =10) as determined by an FDA-approved test.
