A recently published study from the Netherlands appears to indicate that a combination of a pair of immunotherapy drugs can help improve the prognosis of mesothelioma patients with tumors that are not able to be removed through surgery. The experiment, named checkmate 743, compared the use of first-line nivolumab and ipilimumab versus platinum-based chemotherapy in a group of over 600 mesothelioma cancer patients, and showed significant tumor shrinkage for a large portion of the participants who were given the two-drug combination.
Conducted by The Netherlands Cancer Institute and The University of Leiden, in Amsterdam, the study showed a two year survival rate in 41% of the 303 participants given the combination of nivolumab and ipilimumab, contrasted with a 27% survival rate of the 302 patients undergoing platinum-based chemotherapy. For many decades, chemotherapy has been the standard of care for mesothelioma patients diagnosed with tumors that cannot be operated on or otherwise surgically removed.
“CheckMate 743 met its primary endpoint of statistically improved OS with nivolumab + ipilimumab vs standard of care chemotherapy in first-line treatment of patients with mesothelioma,” said Paul Baas, M.D., who presented the study’s findings at The International Association for the Study of Lung Cancer conference. “These clinically meaningful data represent the first positive phase 3 trial of immunotherapy in first-line MPM and should be considered as a new standard of care.”
