Unigene's Licensee, Tarsa Therapeutics, Reports Positive Clinical Data in Phase 2 Study of Oral Calcitonin for Prevention of Postmenopausal Osteoporosis
Results Presented at ASBMR 2012 Show Oral Calcitonin Improves Bone Mineral Density at Lumbar Spine

BOONTON, N.J., Oct. 16, 2012 /PRNewswire/ -- Unigene Laboratories, Inc. (OTCBB: UGNE), a leader in the design, delivery, manufacture and development of peptide-based therapeutics, today announced that its licensee, Tarsa Therapeutics, reported that a Phase 2 trial of its oral recombinant salmon calcitonin in the prevention of postmenopausal osteoporosis was successfully concluded and yielded statistically significant, clinically relevant improvements in bone mineral density (BMD) at the lumbar spine.

The Phase 2 trial evaluated the ability of Tarsa's oral calcitonin tablet to improve BMD at the lumbar spine after one year of daily treatment in postmenopausal women with low bone mass (osteopenia) at increased risk of fracture.  Tarsa's oral calcitonin was superior to placebo in increasing BMD at the lumbar spine in this patient population, and its safety profile did not differ substantially from that of placebo. The Phase 2 study results were the subject of an oral presentation at the American Society for Bone and Mineral Research (ASBMR) 2012 Annual Meeting.

Ashleigh Palmer, Chief Executive Officer, stated, "We are delighted with the positive results from Tarsa's study of oral calcitonin in postmenopausal women with osteopenia.  The safety and efficacy data in this Phase 2 study confirm the positive results that Tarsa achieved in its Phase 3 study of oral calcitonin for the treatment of postmenopausal osteoporosis."

Separately, on Friday, October 12, Tarsa announced an agreement in principle with Therapicon® Slr to provide consulting assistance to the Italian firm in its appeal of the recent recommendation by the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) to limit the use of calcitonin-containing medicines. Therapicon's request for a reexamination of the recommendation has been acknowledged by the CHMP, and a timetable for the reexamination process has been set.

A poster presentation hosted by Tarsa at ASBMR 2012 discussed combined safety data from Tarsa's two recent year-long clinical trials of its oral calcitonin showing that no signal of carcinogenicity was detected.

Palmer commented, "We applaud Therapicon and Tarsa for their strategic, proactive approach towards addressing the unexpected EMA recommendation, which we now understand was based on a retrospective analysis of long finished clinical trials involving certain calcitonin products unrelated to Unigene or its licensees.  We look forward to Tarsa's continued advancement of its oral calcitonin programs and to a satisfactory resolution to Therapicon's CHMP review, which we hope will reaffirm the favorable overall safety and efficacy profile that calcitonin has demonstrated over its nearly 30 years as an approved medicine."
