KENILWORTH, NJ, USA I December 1, 2016 I 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 for review the supplemental Biologics License Application (sBLA) for KEYTRUDA® (pembrolizumab), the company’s anti-PD-1 therapy, for the treatment of patients with refractory classical Hodgkin lymphoma (cHL) or for patients who have relapsed after three or more prior lines of therapy. The FDA granted Priority Review with a PDUFA, or target action, date of March 15, 2017. The sBLA will be reviewed under the FDA’s Accelerated Approval program. In April 2016, KEYTRUDA was granted Breakthrough Therapy Designation by the FDA for this indication.

“Patients with refractory or relapsed classical Hodgkin lymphoma have limited treatment options,” said Dr. Roger Dansey, senior vice president and therapeutic area head, oncology late-stage development, Merck Research Laboratories. “We believe that the expedited review of this sBLA granted by the FDA is an important step in helping us make KEYTRUDA available as quickly as possible to patients living with this disease.”

The application is seeking approval for KEYTRUDA at a fixed dose of 200 mg administered intravenously every three weeks and is based on data from the KEYNOTE-087 and KEYNOTE-013 trials, which studied patients with refractory cHL or who had relapsed after three or more prior lines of therapy. This is the first application for regulatory approval of KEYTRUDA in a hematologic malignancy.

The KEYTRUDA clinical development program includes more than 30 tumor types in more than 360 clinical trials, including nearly 200 trials that combine KEYTRUDA with other cancer treatments. For hematologic malignancies specifically, Merck is conducting broad immuno-oncology research assessing the role of monotherapy and combination regimens with KEYTRUDA (pembrolizumab). The program includes nearly 40 ongoing studies – several of which are registration-enabling trials – across more than 20 hematologic subtypes, including leukemia, lymphomas and myeloma.

About Hodgkin Lymphoma

Hodgkin lymphoma is a type of lymphoma that develops in the white blood cells, called lymphocytes, which are part of the immune system. Hodgkin lymphoma can start almost anywhere – most often in lymph nodes in the upper part of the body, with the most common sites being in the chest, neck or under the arms. In 2016, it is estimated that more than 8,500 people will be diagnosed with Hodgkin lymphoma in the U.S. Classical Hodgkin lymphoma (cHL) accounts for about 95 percent of all cases of Hodgkin lymphoma in developed countries.

About KEYTRUDA® (pembrolizumab)

KEYTRUDA is a humanized monoclonal antibody that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA 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.

KEYTRUDA is administered as an intravenous infusion over 30 minutes every three weeks for the approved indications. KEYTRUDA for injection is supplied in a 100 mg single use vial.

KEYTRUDA Indications and Dosing

Melanoma

KEYTRUDA is indicated for the treatment of patients with unresectable or metastatic melanoma at a dose of 2 mg/kg every three weeks until disease progression or unacceptable toxicity.

Lung Cancer

KEYTRUDA is indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have high PD-L1 expression [tumor proportion score (TPS) ≥50%] as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations.

KEYTRUDA (pembrolizumab) is also indicated for the treatment of patients with metastatic NSCLC whose tumors express PD-L1 (TPS ≥1%) as determined by an FDA-approved test, with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving KEYTRUDA.

In metastatic NSCLC, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression.

Head and Neck Cancer

KEYTRUDA is indicated for the treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) with disease progression on or after platinum-containing chemotherapy. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. In HNSCC, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression.
