KENILWORTH - 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.
The application seeks approval of KEYTRUDA monotherapy for the treatment of patients with Bacillus Calmette-Guerin (BCG)-unresponsive, high-risk, non-muscle invasive bladder cancer (NMIBC) with carcinoma in-situ (CIS) with or without papillary tumors who are ineligible for or have elected not to undergo cystectomy (removal of bladder). This application for KEYTRUDA, which is based on results from the Phase 2 KEYNOTE-057 trial, will be discussed at the Dec. 17 meeting of the FDA's Oncologic Drugs Advisory Committee (ODAC). Data from this trial were first presented at the European Society for Medical Oncology 2018 Congress. Merck anticipates a Prescription Drug User Fee Act (PDUFA), or target action date, in January 2020, based on priority review.
'Merck is steadfast in its commitment to patients with bladder cancer, including advancing research to meet unmet medical needs. Patients with high-risk, non-muscle invasive bladder cancer sometimes make an informed decision to decline, or are medically ineligible for radical cystectomy, and there are currently limited non-surgical treatment options approved by the FDA for these patients who are BCG-unresponsive,' said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. 'We look forward to participating in the advisory committee meeting and to continuing to work with the FDA as they review this supplemental application for KEYTRUDA.'
About Bladder Cancer
Bladder cancer begins when cells in the urinary bladder start to grow uncontrollably. As more cancer cells develop, they can form a tumor and spread to other areas of the body. Bladder cancers are described based on how far they have invaded into the wall of the bladder. NMIBC occurs when the cancer has not grown into the main muscle layer of the bladder. It is estimated that more than 80,000 new cases of bladder cancer will be diagnosed in 2019 in the United States. Approximately 75% of patients with bladder cancer are diagnosed with non-muscle invasive bladder cancer (NMIBC). For high-risk NMIBC patients who are BCG-unresponsive with persistent or recurrent disease, treatment guidelines recommend radical cystectomy, a surgery to remove the entire bladder that often requires removal of other surrounding organs and tissues. In men, removal of the prostate is common, and in women, surgeons may also remove the uterus, fallopian tubes, ovaries and cervix, and occasionally a portion of the vagina.
About KEYNOTE-057
The filing was based on data from KEYNOTE-057 (NCT02625961), a Phase 2, multicenter, open-label, single-arm trial in 102 patients with Bacillus Calmette-Guerin (BCG)-unresponsive, high-risk, non-muscle invasive bladder cancer (NMIBC) with carcinoma in-situ (CIS) with or without papillary tumors who were ineligible for or had elected not to undergo cystectomy (Cohort A). In this study, BCG-unresponsive high risk NMIBC is defined as persistent disease despite adequate BCG therapy, disease recurrence after an initial tumor-free state following adequate BCG therapy, or T1 disease following a single induction course of BCG. Patients received KEYTRUDA 200 mg every three weeks until unacceptable toxicity, persistent or recurrent high-risk NMIBC or progressive disease. Assessment of tumor status was performed every 12 weeks, and patients without disease progression could be treated for up to 24 months. The major efficacy outcome measures were complete response (as defined by negative results for cystoscopy [with transurethral resection of bladder tumor (TURBT)/biopsies as applicable], urine cytology, and computed tomography urography [CTU] imaging) and duration of response.
About KEYTRUDA (pembrolizumab) Injection, 100mg
KEYTRUDA is an anti-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 1,000 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.
