KEYTRUDA plus chemotherapy improves overall survival versus chemotherapy alone to treat advanced malignant pleural mesothelioma: Merck
Malignant mesothelioma is a type of cancer that starts in the linings of certain parts of the body, including the chest, abdomen, heart and testicles.
Rahway: Merck, known as MSD outside of the United States and Canada, and the Canadian Cancer Trials Group (CCTG) have announced that the Phase 2/3 CCTG IND.227/KEYNOTE-483 trial evaluating KEYTRUDA, Merck’s anti-PD-1 therapy, in combination with chemotherapy met its primary endpoint of overall survival (OS) for the first-line treatment of patients with unresectable advanced or metastatic malignant pleural mesothelioma.
IND.227 was sponsored by CCTG, in collaboration with investigators in Italy (co-sponsored by National Cancer Institute of Naples - NCIN), and France (co-sponsored by The French Cooperative Thoracic Intergroup - IFCT); Merck provided KEYTRUDA and support for the trial. At the final analysis of the study, KEYTRUDA plus chemotherapy showed a statistically significant and clinically meaningful improvement in OS compared to chemotherapy alone in these patients. The safety profile of KEYTRUDA in combination with chemotherapy in this study was consistent with previously reported studies. Results will be presented at an upcoming medical meeting and discussed with regulatory authorities worldwide.
“Malignant pleural mesothelioma is a rapidly progressing cancer that develops in the lining of the lungs and has a poor prognosis,” said Dr. Eliav Barr, senior vice president, head of global clinical development and chief medical officer, Merck Research Laboratories. “Patients are in need of new treatments that can improve survival outcomes, and these positive results support the potential of KEYTRUDA in combination with chemotherapy as a first-line treatment for patients with the most common form of malignant mesothelioma.”
“There have been few treatment advances for patients with malignant pleural mesothelioma, which can be challenging to treat through surgery and radiation alone,” said Dr. Quincy Chu, CCTG’s study chair of the IND.227 trial/KEYNOTE-483 trial. “The results from the trial have the potential to make a difference for patients with this disease who have had limited treatment options available to them.”
Merck has an extensive clinical development program in lung cancer and is advancing multiple registration-enabling studies, with research directed at earlier stages of disease and novel combinations.
