The companies will investigate the combination of CRS-207, Aduro’s LADD (live, attenuated double-deleted) based immunotherapy, with KEYTRUDA (pembrolizumab), Merck’s anti-PD-1 therapy, for the treatment of patients with malignant pleural mesothelioma (MPM) whose disease progressed following prior treatment.
Earlier this year, Aduro announced a Phase 2 clinical collaboration with Merck, through a subsidiary, to evaluate the combination of CRS-207 with pembrolizumab for the treatment of gastric cancer.
Natalie Sacks, M.D., chief medical officer at Aduro, said: “Data from our ongoing Phase 1 clinical trial of CRS-207 with standard chemotherapy as frontline treatment for malignant pleural mesothelioma have been very encouraging, including disease control in 94 percent of patients treated with the CRS-207/chemotherapy combination.
“Based on these clinical data, as well as data from preclinical studies that demonstrate synergistic activity of CRS-207 and anti-PD-1 therapy, we look forward to initiating a Phase 2 trial to evaluate the CRS-207/pembrolizumab combination in patients with malignant pleural mesothelioma who have failed prior treatment.”
The multicenter, single-arm, open-label Phase 2 study is designed to evaluate the safety and efficacy of CRS-207 with pembrolizumab in adults with previously treated MPM. The trial is expected to involve approximately 35 patients who have failed one to two prior treatments.
