Esophageal Cancer

February 1, 2010

GenVec reported long term results from a phase II trial of TNFerade for the treatment of esophageal cancer. The dose escalation study enrolled 24 subjects with locally advanced resectable disease. Prior to surgery, TNFerade was administered weekly for five weeks via intratumoral injections in combination with cisplatin, infusional 5-FU, and radiation. Successive dosing cohorts received TNF at 4x108, 4X109, 4x1010, and 4x1011 PU. Five year follow-up was reached in 3 out of 4 groups (4x108 - 4x1010 PU) and showed an overall five-year survival rate of 56% in these three groups combined. The overall survival rate for the entire cohort was 42% and the overall median survival was 47.7 months. At the 4x109 PU dose, a pathological complete response (pCR) was seen in 100% of resected tumors, with a radiographic CR in a fourth subject; all four remained disease-free up to 48 months. At the 4x1010 PU dose, pCR was seen in 25% of resected tumors and the median survival has not yet been reached. The median survival for the 4x108 and 4x1011 PU doses is 47.4 and 30.4 months, respectively.

Long-term phase III trial results support the potential of Axcan Pharma's Photofrin photodynamic therapy (PDT) for the prevention of esophageal cancer. The trial included 208 subjects with high-grade dysplasia associated with Barrett's Esophagus. In the long-term analysis, 138 subjects in the Photofrin PDT group and 70 subjects in the comparative group (omeprazole alone) were followed for a minimum two-year period. Results showed that esophageal cancer occurred in 13% of subjects treated with Photofrin PDT, compared to a rate of 27% for omeprazole-treated subjects.
