Press Release: Neose Technologies Presents Positive NE-180 Phase I Clinical Trial Data

Neose Technologies Presents Positive NE-180 Phase I Clinical Trial Data at American Society of Hematology Annual Meeting HORSHAM, Pa -- Neose Technologies, Inc. presented positive data from its NE-180 Phase I clinical trial during the American Society of Hematology 48th Annual Meeting and Exposition. The data were presented in a poster entitled, “NE-180, a Novel GlycoPEGylated™ Erythropoietin, Demonstrates Dose-Dependent Activity in a Phase 1, Single Dose, Dose Escalation Study in Normal Human Volunteers” on December 9, 2006. NE-180 is being developed for the treatment of anemia associated with chronic kidney disease, including patients on dialysis and patients not on dialysis, and for the treatment of anemia in adult cancer patients with non-myeloid malignancies receiving chemotherapy. Conclusions from the study are as follows: > Single doses of NE-180, up to 1.5mcg/kg, were generally well-tolerated with no serious adverse events. > Single doses of NE-180 demonstrated potent, dose-dependent erythropoietic activity. > The results from the Phase I study support a Phase II program in patients with anemia associated with chronic kidney disease, dosed every four weeks, and in cancer patients receiving chemotherapy, dosed every three weeks. The full poster presentation can be found on the Neose website via the following link: “We are excited by the data generated in this Phase I trial, particularly the increases in reticulocytes and hemoglobin.
