Unigene to Advance Phase 2 Development of Oral PTH Program by Entering into an Amended and Restated Exclusive Worldwide Li

Phase 2 study for treatment of osteoporosis in postmenopausal women expected to commence in Q1 2011; Unigene to receive $4M upfront for development costs and $4M upon completion of Phase 2 patient enrollment

BOONTON, N.J.--(BUSINESS WIRE)-- Unigene Laboratories, Inc. (OTCBB: UGNE) today announced that the Company entered into an amended and restated exclusive worldwide license agreement with GlaxoSmithKline (GSK) to develop and commercialize an oral formulation of a recombinantly produced parathyroid hormone (PTH) analog for the treatment of osteoporosis in postmenopausal women and plans to initiate a Phase 2 study in the first quarter of 2011.

Under the terms of the amended and restated agreement, Unigene will conduct the Phase 2 study and will be eligible to receive the remaining milestone payments of up to $142M including an upfront payment of $4M, an additional $4M payment upon completion of Phase 2 patient enrollment and further payments based on the achievement of regulatory and commercialization milestones. In addition, Unigene is eligible to receive tiered low double-digit royalties on global sales. Once the Phase 2 study has been completed and based on a review of the data, GSK may elect to assume responsibility for all future development and commercialization of the product.

In April 2002, GSK and Unigene signed the original exclusive worldwide license agreement to develop and commercialize the oral PTH program for osteoporosis with potential payments totaling approximately $150M upon the successful achievement of development and commercialization milestones. Prior to the revised agreement, an aggregate of $8M in up-front and milestone payments were made to Unigene. In addition, Unigene was entitled to reimbursement for development expenses, as well as tiered low double-digit royalties on global sales.

Ashleigh Palmer, Chief Executive Officer of Unigene Laboratories, Inc., said, “Over the past several months we have been focused on multiple strategic imperatives, including working closely with GSK on prioritizing the advancement of our oral PTH Phase 2 program for osteoporosis.” Palmer continued, “The completion of our amended agreement with GSK provides a clear path forward for the PTH program and is a significant milestone for Unigene. This is a strong validation of our new management team’s commitment to our strategy and our ability to deliver results. Importantly, we now have the financial resources needed to continue to advance our oral PTH program. We are thrilled to be continuing our collaboration with GSK to advance our oral PTH program while leveraging their impressive global clinical, regulatory and commercial expertise.”

About the Oral PTH Phase 2 Study

Unigene plans to initiate the Phase 2 oral PTH study in the first quarter of 2011. This multicenter, double blind, randomized, repeat dose placebo controlled study will include an open label comparator arm and will evaluate approximately 90 postmenopausal osteoporotic women for a period of 24 weeks. The primary endpoint will be an increase in bone mineral density in subjects at 24 weeks compared to baseline. Patient enrollment for this study is expected to be completed in the first half of 2011.

About Osteoporosis

Osteoporosis is a disease in which bones become brittle and so are more likely to break. In osteoporotic women and men, the density and quality of bone are reduced, leading to deterioration of the skeleton and increased risk of fracture. It's often diagnosed only after an osteoporosis-related fracture happens because prior to such an event, the patient has no outward signs or symptoms. The disease has a significant impact on patients' quality of life and it is estimated that one in three women and one in five men over the age of 50 will develop osteoporosis during their lifetimes.

The prevalence of osteoporosis is growing as the number of post-menopausal women rises, along with the general increase in life expectancy. Osteoporosis affects an estimated 75 million people in Europe, the US and Japan. In women over 45, osteoporosis accounts for more days spent in hospital than many other diseases, including diabetes, heart attack and breast cancer. There is currently no cure for osteoporosis, but available treatments can strengthen bones and help reduce the risk of fractures.
