SOUTH SAN FRANCISCO, Calif., April 30, 2012 (GLOBE NEWSWIRE) -- OXiGENE, Inc. (Nasdaq:OXGN), a clinical-stage, biopharmaceutical company developing novel therapeutics to treat cancer, announced today that data were presented from a pre-specified subgroup analysis of the FACT trial, a randomized, controlled Phase 2/3 study of ZYBRESTAT® (fosbretabulin tromethamine, CA4P) in patients with anaplastic thyroid cancer (ATC), at the 2012 Annual Meeting of the American Association of Endocrine Surgeons (AAES). A subgroup analysis compared patients on the FACT study who underwent prior cancer-related surgery (thyroidectomy) followed by fosbretabulin and chemotherapy to patients without surgery who received chemotherapy alone. The results showed that improvements were observed in median survival and one-year survival for patients with prior thyroidectomy followed by fosbretabulin and chemotherapy.
