PARP Inhibitors Could Enhance Immunotherapy Response in Mesothelioma
A new study suggests that drugs known as PARP inhibitors may enhance immunotherapy response in mesothelioma patients. According to a report published in the Journal of Clinical Investigations, PARP inhibitors worked especially well in cancers with mutations in their DNA repair genes. Some malignant mesothelioma patients have mutated DNA repair genes. In these patients, a PARP inhibitor may modify immunotherapy response, making drugs like Keytruda work better. How PARP Impacts Immunotherapy Response PARP stands for poly (ADP-ribose) polymerase. It represents a family of proteins involved in a number of cellular processes, including DNA repair. PARP is also involved in apoptosis, or programmed cell death. Olaparib (Lynparza) is an example of a PARP inhibitor. PARP inhibitors attack tumors that already have…
