Urocortin 2 for Congestive Heart Failure (CHF) Continues Preclinical Evaluation

Initiation of longer term (up to 72 hours in duration) Phase II clinical trials of urocortin 2 are awaiting additional preclinical data. The Company has identified five preclinical studies necessary to support the longer period of infusion in the clinical program. Two of these five preclinical studies were successfully completed by July 2008. The two completed studies were non- GLP toxicology and safety assessment studies over 14 days of continuous infusion in distinct species models. The favorable results of these studies now await confirmation in the GLP preclinical studies anticipated later in 2008.
