European Medicines Agency Adopts Positive Opinion for Merck’s KEYTRUDA® (pembrolizumab) in Combination with Chemotherapy for First-Line Treatment of Adults with Metastatic Squamous Non-Small Cell Lung Cancer (NSCLC)

Recommendation Based on Significant Overall Survival Benefit Demonstrated with KEYTRUDA in Combination with Chemotherapy in Pivotal KEYNOTE-407 Trial

KENILWORTH, NJ, USA I February 4, 2019 I Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending KEYTRUDA, Merck’s anti-PD-1 therapy, in combination with carboplatin and either paclitaxel or nab-paclitaxel, for the first-line treatment of metastatic squamous non-small cell lung cancer (NSCLC) in adults. This recommendation is based on results from the pivotal, Phase 3 KEYNOTE-407 trial, which enrolled patients regardless of PD-L1 tumor expression status. The trial showed a significant improvement in overall survival (OS) and progression-free survival (PFS) for patients taking KEYTRUDA in combination with chemotherapy (carboplatin and either paclitaxel or nab-paclitaxel) compared with chemotherapy alone. If approved, this would mark the first approval in Europe for an anti-PD-1 therapy in combination with chemotherapy for adults with metastatic squamous NSCLC.

“We are pleased by today’s positive opinion from the CHMP, which brings us one step closer to potentially expanding our lung cancer indications in Europe to include first-line combination therapy for patients with metastatic squamous non-small cell lung cancer, regardless of PD-L1 expression,” said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. “This is important as squamous cell carcinoma continues to be an area of unmet need, and there was a significant overall survival benefit observed in the Phase 3 KEYNOTE-407 trial.”

Data from KEYNOTE-407 were presented at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting and were published in The New England Journal of Medicine. The CHMP’s recommendation will now be reviewed by the European Commission for marketing authorization in the European Union (EU). The decision by the European Commission is expected in the first quarter of 2019.

KEYNOTE-407 is part of Merck’s leading clinical development program in lung cancer, which includes 10 Merck-sponsored Phase 3 trials. These trials are evaluating KEYTRUDA in combination with other treatments and as monotherapy, in both advanced and earlier stages of disease, as well as across different histologies and lines of treatment.

About Lung Cancer in Europe

Lung cancer, which forms in the tissues of the lungs, usually within cells lining the air passages, is the leading cause of cancer death in Europe and worldwide. In 2018, there were nearly 388,000 deaths from lung cancer in Europe. The two main types of lung cancer are non-small cell and small cell. NSCLC is the most common type of lung cancer, accounting for about 85 percent of all cases. There are several subtypes of NSCLC, including adenocarcinoma (accounting for 40 percent of lung cancers), squamous cell carcinoma (25 to 30 percent) and large cell carcinoma (10 to 15 percent).

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 900 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.
