Dynogen Pharmaceuticals, Inc. announced today that dosing has begun for a double-blinded, placebo controlled Phase 1b trial designed specifically to examine DDP733 on the functional changes associated with gastroesophageal reflux. In addition to examining safety, the trial will be powered to yield important efficacy data to support the use of DDP733 as a treatment for nocturnal gastroesophageal reflux (NGERD). Dynogen is developing DDP733 for NGERD as an adjunctive treatment with current GERD therapies. DDP733 is also being studied by Dynogen for irritable bowel syndrome with constipation (IBS-c) in a Phase 2 clinical study.

Dynogen Pharmaceuticals, Inc. announced today that it has initiated a Phase II proof-of-concept trial of DDP225 for diarrhea-predominant irritable bowel syndrome (IBS-d), and the first patients have been dosed. DDP225 is an orally-active compound that targets two key pathways that control the gastrointestinal (GI) system, thus giving it the potential to address multiple symptoms associated with IBS-d. This DDP225 Phase II trial is a randomized, double-blind, placebo controlled study that is enrolling patients with IBS-d at multiple centers in Canada and is assessing safety and pharmacodynamic efficacy as well as symptom-based endpoints. In September 2005, Dynogen began dosing patients in a Phase II study of DDP733 for the treatment of patients with constipation-predominant IBS (IBS-c), the other common form of IBS.

In its largest financing to date, Dynogen Pharmaceuticals Inc. secured $50 million in a Series B round, enabling it to build its pipeline and advance its two clinical com- pounds.
