Higher Doses of Tarextumab Appear to Correlate with Improved Progression-free and Overall Survival
REDWOOD CITY, Calif., Feb. 22, 2016 (GLOBE NEWSWIRE) -- OncoMed Pharmaceuticals Inc. (NASDAQ:OMED), a clinical-stage company developing novel anti-cancer stem cell and immuno-oncology therapeutics, announced updated survival data from a Phase 1b clinical trial of tarextumab (anti-Notch2/3, OMP-59R5) for the treatment of small cell lung cancer.
The Phase 1b dose-escalation trial enrolled 27 previously untreated patients with extensive-stage small cell lung cancer to assess the safety, biomarker, and anti-tumor activity of tarextumab in combination with etoposide and platinum-based chemotherapy. Doses of tarextumab ranged from 5 mg/kg to 15 mg/kg and a Phase 2 combination dose of 15mg/kg every three weeks was selected. Among all patients in the trial, median progression-free survival (PFS) was 4.4 months and the median overall survival (OS) was 10.3 months. Additional survival benefit was observed in 15 patients who received higher doses of tarextumab (at or above 12.5 mg/kg every three weeks) in combination with standard-of-care therapy, with a median PFS of 5.8 months and median OS of 16 months.
"These more mature follow-up data from our Phase 1b trial of tarextumab plus chemotherapy in small cell lung cancer patients provide early signs of encouraging efficacy. Of note, we are seeing a dose-efficacy association with a manageable side effect profile for tarextumab in the small cell lung cancer Phase 1b clinical trial. This Phase 1b data supports our ongoing Phase 2 PINNACLE trial," said Jakob Dupont, M.D., OncoMed's Chief Medical Officer. "Small cell lung cancer responds quickly to chemotherapy, but has a high rate of recurrence. By targeting cancer stem cells, and Notch3 in particular, we hope to have a positive impact on patient outcomes."
