ChemoCentryx, Inc. announced positive overall survival (OS) results from an ongoing Phase Ib clinical trial of the company’s second CCR2 inhibitor – CCX872 – in the treatment of locally advanced/metastatic pancreatic cancer. The study demonstrated OS of 29% at 18 months with CCX872 and FOLFIRINOX combination therapy in all patients treated. The OS rate of 29% in the present study of CCX872 compares favorably with previously published OS rates of 18.6% using FOLFIRINOX alone to treat pancreatic cancer patients with metastatic disease. The findings will be presented during the ASCO-SITC Clinical Immuno-Oncology Symposium, being held January 25-27, 2018 in San Francisco, CA. The ongoing, Phase Ib, multi-center, open-label clinical trial of CCX872 for advanced pancreatic cancer completed enrollment in March 2016. All patients enrolled in the trial had advanced non-resectable pancreatic cancer (76% of patients having metastatic disease), and an Eastern Cooperative Oncology Group (ECOG) Performance Status score of less than or equal to 2. Fifty patients received FOLFIRINOX (fluorouracil [5-FU], leucovorin, irinotecan, oxaliplatin) once every two weeks (maximum 12 cycles) plus daily doses of CCX872 for 12 weeks. Patients showing at least stable disease at the end of the 12-week treatment period were eligible to continue CCX872 treatment until disease progression. Patients were followed for OS and blood samples were taken at baseline and at intervals throughout the active treatment period for hematologic and flow cytometric analysis of circulating immune cell populations. At 18 months, better OS was associated with lower peripheral blood monocyte counts at baseline. The presentation at ASCO-SITC will be the first publication of OS data at 18 months.
