BioGeneriX and Neose Technologies Announce Positive Data from Two Phase I Studies of GlycoPEG-GCSF

BioGeneriX AG, a member of the ratiopharm Group of companies, and Neose Technologies, Inc. (NasdaqGM:NTEC) today announced positive data from two Phase I clinical studies of GlycoPEG-GCSF. GlycoPEG-GCSF is being co-developed by the companies for the treatment of neutropenia associated with myelosuppressive chemotherapy. The first Phase I study evaluated a randomized, weight-based, single ascending dose of GlycoPEG-GCSF compared to Neulasta® in 53 healthy subjects. Conclusions from this trial are as follows: Single doses of GlycoPEG-GCSF demonstrated potent stimulation of neutrophils and mobilization of peripheral blood progenitor cells. GlycoPEG-GCSF demonstrated an approximately 30% greater absolute neutrophil count response versus Neulasta. GlycoPEG-GCSF demonstrated an approximately 60% increased bioavailability versus Neulasta®. Single doses of GlycoPEG-GCSF, up to 100 µg/kg, were generally well-tolerated with no serious adverse events. Adverse events were comparable to those for Neulasta® and there were no discontinuations due to adverse events. There were no antibodies to GlycoPEG-GCSF detected. The second Phase I study evaluated a 6 mg dose of GlycoPEG-GCSF versus a 6 mg dose of Neulasta® in 36 healthy subjects. Conclusions from this trial are as follows: GlycoPEG-GCSF demonstrated potent stimulation of neutrophils and mobilization of peripheral blood progenitor cells. GlycoPEG-GCSF demonstrated an approximately 30% greater absolute neutrophil count response versus Neulasta. GlycoPEG-GCSF demonstrated an approximately 60% increased bioavailability versus Neulasta®. GlycoPEG-GCSF was generally well-tolerated with no serious adverse events. Adverse events were comparable to Neulasta, and there were no discontinuations due to adverse events. There were no antibodies to GlycoPEG-GCSF detected. "We are excited by the data generated in these Phase I trials. We look forward to moving into Phase II in the first half of 2008,” said Dr. Karl Heinz Emmert, BioGeneriX chief scientific officer. "We are encouraged by the emerging product profile for our GlycoPEG-GCSF candidate. We look forward to determining whether the intriguing increases in absolute neutrophil count and bioavailability seen in the Phase I studies will continue to be evident in patients receiving chemotherapy in Phase II," said George J. Vergis, Ph.D., Neose president and chief executive officer.” Conference Call As previously announced, a conference call will be held this morning at 8:00 a.m. (EST) to review the Phase I data in detail. The call is expected to last approximately 30 minutes and will include prepared remarks by Neose and BioGeneriX with a subsequent question and answer period.

About G-CSF and Neutropenia G-CSF is prescribed to stimulate the production of neutrophils, and is approved for sale in major markets around the world for the treatment of neutropenia associated with myelosuppressive chemotherapy. Worldwide sales in the G-CSF category exceeded $4 billion in 2006. Neutropenia is a severe reduction in the number of neutrophils (mature white blood cells) in the circulating blood, commonly associated with cancer chemotherapy. Patients with neutropenia are at increased risk of developing serious infection. If not treated promptly, neutropenia can be life-threatening.
