Genaera Corporation Announces Presentation Of Data On Trodusquemine Mechanism Of Action In Obesity

Announced that data supporting the mechanism of action of trodusquemine, the Company’s centrally-acting small molecule appetite suppressant, was presented at the Keystone Symposia Obesity Meeting taking place in Keystone, Colorado, January 14-19, 2007 by Kristen Lantz, PhD, Research Scientist.

January 16th, 2007 -- Genaera Corporation (NASDAQ: GENR) today announced that data supporting the mechanism of action of trodusquemine, the Company’s centrally-acting small molecule appetite suppressant, was presented at the Keystone Symposia Obesity Meeting taking place in Keystone, Colorado, January 14-19, 2007 by Kristen Lantz, PhD, Research Scientist.

Summarizing pre-clinical evaluations of trodusquemine performed to date, the presentation described a multi-factorial mechanism of action through which trodusquemine suppresses appetite, induces loss of body weight and normalizes blood glucose and blood cholesterol levels. This includes the selective inhibition of protein tyrosine phosphatase 1B (PTP1B), the inhibition of neurotransmitter reuptake transporters (dopamine and norepinephrine) and the downregulation of orexigenic hormone expression (AgRP and NPY) to decrease appetite and induce fat loss.

“These data confirm that trodusquemine is active against several critical molecular targets involved in the regulation of appetite, body weight, and insulin sensitivity, that may give it broad utility in treating obesity and related conditions,” said Jack Armstrong, President and CEO of Genaera Corporation. “We expect to begin exploring the potential of trodusquemine in humans with a Phase I clinical trial in the first half of 2007.”

About Trodusquemine

Trodusquemine (MSI-1436) is a centrally-acting appetite-suppressant discovered at Genaera that has been shown to cause weight loss and normalize both fasting blood glucose and blood cholesterol levels in animal models of obesity.

Genaera has conducted studies in a number of mouse models of obesity (including diet-induced obese (DIO) mice, agouti mice, leptin deficient and leptin receptor deficient mouse strains). This preclinical activity of trodusquemine reduces food intake by appetite suppression and is reversible. The ability of trodusquemine to induce weight loss without associated toxicities in several animal models (rodent, rabbit, dog and monkey) supports selection of this compound as a candidate for evaluation in clinical studies.
