SAN DIEGO, Dec. 5 /PRNewswire-FirstCall/ -- ADVENTRX Pharmaceuticals, Inc. (Amex: ANX), a biopharmaceutical research and development company focused on commercializing proprietary product candidates for the treatment of cancer and infectious diseases, announced today that it has completed patient enrollment in its Phase 2 clinical trial of ANX-510, or CoFactor, for the treatment of advanced breast cancer.

"Data on the primary endpoint in this study, along with overall survival data from our Phase 2b study and available data from our discontinued Phase 3 study, all of which we expect in the second quarter of 2008, will expand our understanding of CoFactor's safety and efficacy," said Evan M. Levine, chief executive officer of ADVENTRX. "By mid-next year we should have greater insight into our ability to develop CoFactor in breast cancer and other indications."

The Phase 2 clinical trial is a single arm, multicenter study to evaluate the safety and efficacy of treatment with CoFactor plus 5-fluorouracil (5-FU) in advanced breast cancer patients who have failed anthracycline and taxane chemotherapies. Patients are treated with CoFactor followed by 5-FU administered by IV bolus weekly for 6 weeks, with tumor and safety assessments every 8 weeks. The primary endpoint for the study is objective response rate as defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria, and secondary endpoints are duration of response, progression free survival, overall survival and incidence and severity of adverse events, as defined by the National Cancer Institute (NCI) Common Terminology Criteria. A total of 32 patients were enrolled in this study.
