Unigene Presents Positive Advanced Preclinical Data for UGP281 a Potent, Orally Delivered Anorexigenic Peptide in a Late-Breaking Poster Presentation at the American Diabetes Association 71st Scientific Sessions

-UGP281 demonstrated significant and sustained weight reduction over several weeks using oral formulation-

-Unigene expects to file IND and commence Phase 1 studies in 1H 2012-

BOONTON, N.J.--(BUSINESS WIRE)--Jun 27, 2011 - Unigene Laboratories, Inc. (OTCBB: UGNE) a leader in the design, delivery, manufacture and development of peptide-based therapeutics announced today that the Company presented positive preclinical data for UGP281, its potent, orally-delivered anorexigenic peptide as a late-breaking poster presentation at the American Diabetes Association (ADA) 71st Scientific Sessions being held June 24-28 in San Diego, California.

Poster Presentation

Titled: “Preclinical Studies with UGP281, a Potent, Orally Delivered, Anorexigenic Peptide”, and authored by N. Mehta, W. Stern, A. Sturner, S. Carl, V. Ray, A. Conslavo, C. Sisk, F. Ritacco, N. Souders, S. Pennington, J. Jiacchi, K. Veintimilla, C. Meenan, A. Vryhoff and A. Bolat.


UGP281 is a peptide hormone analog that shows an acute dramatic reduction in food intake in a rat model at low doses. The peptide has been produced by recombinant expression in E. coli and has also been formulated in enteric-coated capsules for oral delivery. The effect of UGP281 on food intake and body mass has been investigated in several preclinical studies. In a 20 day chronic dosing study, young rats injected daily with UGP281 at doses of 5 µg/kg and 20 µg/kg exhibited an immediate acute dose dependent reduction in food intake of 55% and 84%, respectively and a sustained weight loss relative to placebo of 5.7% and 8.8%, respectively. A placebo-controlled study in Beagle dogs with enteric-coated capsules containing UGP281 demonstrated a sustained weight reduction of >8% compared to placebo for a period of 5 weeks. In comparative studies at comparable concentrations, UGP281 demonstrates greater reductions in body weight than other peptide drugs currently in development. Based on the results to date, UGP281 was well tolerated and offers the potential of a patient friendly orally dosed peptide therapy for the management of obesity.

Nozer Mehta, Vice President, Biological Research and Development commented, “We are pleased with our continued progress with UGP281 and thrilled to have the opportunity to showcase our advancements in a late-breaking poster presentation at a prestigious meeting such as the ADA's 71st Scientific Sessions.” Dr. Mehta continued, “Our peptide's selective receptor-binding is anticipated to result in a more attractive safety profile relative to several of the small molecule drugs or drug combinations currently, or previously, in development. Unigene's “Peptelligence™” branded core competence will also allow UGP281 to be manufactured and dosed by way of our proprietary recombinant production and oral drug delivery technologies. These proprietary attributes will further differentiate UGP281, especially from potential competitors with peptide or protein based drugs that require injectable, depot or patch formulations. Hence, we believe we have the means to effectively position UGP281 in this important market space.”

Unigene expects to file an Investigational New Drug application (IND) with the U.S. Food and Drug Administration (FDA) and commence a Phase 1 study with UGP281 in the first half of 2012.
