“As a leader in lung cancer research, we continue to try to advance science for our patients by building upon the standard we set several years ago with KEYTRUDA,” said Dr. Gregory Lubiniecki, Vice President, Global Clinical Development, Merck Research Laboratories. “While these results are not what we hoped for, we are proud of the foundational role that KEYTRUDA has established in the treatment of certain types of lung cancer, and we are committed to continuing to research how we can further improve responses to our medicines for patients with difficult-to-treat forms of the disease.”
