VIAject is an investigational ultra-rapid-acting injectable human insulin which Biodel is developing as a treatment for diabetes.
The company said that in a poster presentation at the American Diabetes Association 69th Scientific Sessions, Dr. Roderike Pohl and colleagues from Biodel described results of in vitro studies to explain VIAject's mechanism of absorption and rapid onset of action (poster #438, Rapidity of Hexameric Dissociation of Various Prandial Insulin Formulations). VIAject was shown to have a smaller mean particle size compared to rapid acting insulin analogs and regular human insulin. These data are consistent with an increased proportion of monomeric/dimeric insulin after injection into the subcutaneous space, a key contributor to VIAject's more rapid absorption that has been previously demonstrated in clinical studies.
In a separate presentation on Saturday, Dr. Thomas Forst and colleagues from the Institute for Clinical Research and Development (ikfe), Mainz, Germany, described results of a clinical study comparing the effect of VIAject to regular human insulin and insulin lispro on markers of oxidative stress and endothelial function following a liquid test meal in patients with type 2 diabetes (poster #1304, Postprandial Vascular Effects of VIAject Compared with Insulin Lispro and Regular Human Insulin in Patients with Type 2 Diabetes Mellitus). VIAject was found to be the most effective of the three insulins in reducing post-prandial oxidative stress and improving microvascular blood flow and function. These findings were presented previously at the Eighth Annual Diabetes Technology Meeting in November 2008.

Dr. Solomon Steiner, chairman and chief executive officer of Biodel, said: "These poster presentations support our belief that VIAject has unique pharmacologic attributes and clinical effects which make it a very promising drug candidate for the treatment of diabetes. Our VIAject characterization work demonstrated meaningful differences between VIAject and other insulins which may explain its more rapid absorption profile, while measures of oxidative stress and tissue blood flow in patients receiving three different insulin therapies favored VIAject. These findings are encouraging and suggest to us that VIAject has significant clinical and commercial potential as a treatment for diabetes.
"I also wish to congratulate our board member and good friend, Dr. Daniel Lorber, on his receipt of the ADA's Outstanding Physician Clinician in Diabetes Award. Dr. Lorber is a well-known expert on the treatment of diabetes, a former member of the ADA board of directors, and very deserving of this prestigious honor."
