Proteo, Inc. / Proteo Biotech AG: Start of the Phase II clinical trial with Elafin

Irvine, CA – Kiel, 17th November, 2008 – Proteo Inc. (OTCBB: PTEO; WKN: 925981) and its wholly-owned subsidiary Proteo Biotech AG announced today the beginning of patient recruitment for a Phase II clinical trial.

In this randomized, placebo-controlled Phase II trial the effect of Elafin on inflammatory parameters will be investigated in patients undergoing esophagectomy for esophagus carcinoma. The trial will be performed under the direction of Prof. Fred Fändrich, Department of General and Thoracic Surgery, University of Kiel: »The removal of the esophagus for esophageal cancer is a very invasive surgical procedure that frequently requires long stays in intensive care units. No drugs are currently available which substantially alleviate the inflammatory reaction of the body to this surgical treatment. I am therefore particularly pleased that we have the opportunity to conduct the first clinical trial worldwide on the therapeutic efficacy of the drug candidate Elafin.«

»As the second largest university hospital in Germany, the University Hospital of Schleswig-Holstein offers an ideal infrastructure for performing a trial of this type. We are confident that the results of the trial will provide confirmation of the mode of action (proof of concept) and so promote our multifaceted development program for Elafin,« announced Birge Bargmann, CEO of Proteo.

Prof. Oliver Wiedow, who discovered Elafin and founded Proteo, draws a positive balance: »With the start of this trial we are also setting a new milestone for biotechnology in Kiel. The close cooperation of many committed colleagues at the University Hospital, the state's economic development fund and Proteo Biotech AG, has made it possible to promote in Schleswig-Holstein the development of a pharmaceutical, that was discovered in the Department of Dermatology at the University of Kiel, and to make this drug substance available for the first time to patients within the framework of a clinical trial.«

About Elafin

The drug candidate Elafin is produced naturally in humans and inhibits enzymes responsible for the formation of circulating factors (cytokines) that promote inflammatory reactions. The release of these cytokines is increased after major surgery and is responsible for an inflammatory reaction that can affect all vital organs. In the planned trial it is expected that Elafin will impair the formation of these cytokines and thus have a positive effect on the inflammatory reaction.

The excellent tolerability of Elafin in human subjects was demonstrated in a Phase I clinical single dose escalating study. On recommendation of the European Medicines Agency (EMEA), Proteo Biotech AG received orphan drug status from the EU commission for its candidate drug Elafin for the treatment of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension.
