Unigene's Proprietary Peptelligence™ Platform Selected by Stealth Peptides for an Oral Phase 1 Clinical Study

BOONTON, N.J., March 5, 2012 /PRNewswire/ -- Unigene Laboratories, Inc. (OTCBB: UGNE), today announced that the Company signed a Clinical Manufacturing Services Agreement with Stealth Peptides Inc. (Stealth).  Unigene will use its validated, proprietary Peptelligence™ platform as part of the agreement to support Phase 1 clinical plans for one of Stealth's investigational drug candidates.  Stealth's Phase 1 clinical study is expected to begin later this year.

Stealth recently commenced an oral feasibility study for its pipeline candidate in August 2011.  After analyzing the data produced using Unigene's oral delivery technology relative to competitive technologies, Stealth chose to move forward into a clinical evaluation with the Peptelligence™ platform.

No financial terms from the agreement were disclosed.

Gregory Mayes, Unigene's Chief Business Officer, stated, "We are very pleased our validated oral delivery and manufacturing technology platforms were chosen by Stealth to advance its therapeutic candidate into an oral Phase 1 clinical study and look forward to supporting that work this year as well as longer term.  Our goal is to continue this momentum as we further exploit the potential of Unigene's Peptelligence™ platform by providing proprietary solutions to the development strategies of our partners.  Our successful, ongoing collaboration with Stealth epitomizes the value of Unigene's Peptelligence™ platform in the development of novel classes of oral peptide therapeutics.  This is the second clinical manufacturing services agreement we have executed since launching our Biotechnologies SBU just a little over a year ago.  We are making tremendous progress and fully expect we will continue to add additional feasibility studies to our fast growing portfolio over the course of this year.  We are confident we will convert at least one feasibility study into a definitive licensing agreement within the next 6-9 months."

Travis Wilson, CEO of Stealth, commented, "Unigene has been instrumental in providing its unique technologies to our pipeline compounds and opening up additional areas of clinical development.  Both scientifically, via its Peptelligence™ platform, and strategically, given its depth of knowledge and experience, Unigene is becoming the leader in oral peptide formulation development strategies.  Based on the success of our feasibility studies, we look forward to a successful Phase I study for our novel clinical candidate, which could offer a potential breakthrough in the treatment of chronic diseases with unmet needs."
