Antares Reports On End of Phase II Meeting with FDA for Anturol(TM)

Anturol to Proceed to Phase III Pivotal Study for Overactive Bladder

EXTON, Pa.--(HSMN NewsFeed)--June 26, 2006--Antares Pharma, Inc. (Amex:AIS ) announced that an end of Phase II meeting was held with the U.S. Food and Drug Administration (FDA), based on the positive Phase II clinical study results for Anturol(TM), its oxybutynin gel product for the treatment of overactive bladder (OAB). Antares plans to initiate a Phase III clinical program in patients with urge and mixed urinary incontinence pending finalization of protocol specific details. The Phase III protocol is currently defined as a randomized, double-blinded, placebo-controlled multi-center study evaluating the effect of 12 weeks of Anturol treatment in patients. It is expected to support an optimized regulatory strategy with submission of an NDA anticipated before the end of 2007.

"We are pleased with the outcome of the end of Phase II meeting with the FDA and we believe our final protocol will provide Antares with an efficient pathway for approval of Anturol," commented Dario N. Carrara, PhD, Managing Director of Antares Pharma's Pharmaceutical operations in Basel, Switzerland.

In February 2006, Antares announced the results of its Anturol Phase II program in 48 healthy subjects. Each subject received three different doses (parallel three-treatment design) over 20 consecutive days. Anturol was found to be well tolerated at all doses with a reduced adverse event profile in comparison to those reported in both oral and adhesive patch formulations, the only treatments currently available.

Jack E. Stover, Antares' President and Chief Executive Officer, said "We are pleased to be able to continue the development program for Anturol as we explore opportunities with potential marketing partners. Anturol is an important new formulation and method of treatment for OAB which we believe will be well positioned to compete in the growing urinary incontinence market."

Anturol, the Company's transdermal gel product, is targeted for the treatment of OAB a common urological condition. Anturol is a clear, odorless and cosmetically appealing gel formulation of oxybutynin that is designed for optimized absorption through the skin following once-a-day application to the abdomen. The formulation utilizes Antares' proprietary Advanced Transdermal Delivery (ATD(TM)) platform.

According to SG Cowen & Co.'s Therapeutic Categories Outlook (March 2006), OAB affects an estimated 17 million Americans and is one of the fastest growing segments in the urology market. It is characterized by involuntary muscle contractions leading to loss of urine. Symptoms include urinary frequency, urgency, and urge incontinence.
