Collaborators Aim to Identify OC Patients Likely to Benefit from New Combo Therapy
The University of New Mexico (UNM) Comprehensive Cancer Center and the New Mexico Alliance for Cancer Care have entered a collaboration with Personalis to use its cancer immunogenomics platform to identify which ovarian cancer patients respond to a new combination therapy — Lynparza (olaparib) plus the investigational immunotherapy tremelimumab. The combination is being tested in an ongoing Phase 1/2 clinical trial (NCT02571725) in women with BRCA-mutated epithelial ovarian, fallopian tube, or primary peritoneal carcinoma who received at least one prior course of platinum-based chemotherapy. The study, led by Sarah Adams, MD, associate professor at the UNM Comprehensive Cancer Center, is recruiting 50 patients across five sites in the United States.

In cancer treatment, blocking PARP keeps cancer cells from repairing their damaged DNA, causing them to die. In ovarian cancers, these treatments extend the time patients live without their disease getting worse, but they have largely failed to improve overall survival. In a 2015 study, Adams and her team found that by killing ovarian cancer cells, PARP inhibitors create a highly immunogenic environment, which can make tumors sensitive to immune therapy.
