Antares Reports Product Progress in Growing Women's Health Portfolio
Testosterone ATD(TM) Gel Development Pathway Clarified by FDA

Antares Pharma, Inc. (AMEX:AIS) reports that its low-dose testosterone ATD gel for the treatment of FSD (female sexual dysfunction) has had the regulatory pathway for approval clarified by the U.S. Food and Drug Administration (FDA).

Clarification of a regulatory pathway from the FDA for testosterone ATD gel is very important news that reopens the prospects for approval in the U.S. as well as in Europe, each large potential markets, after several years of little regulatory progress. It also demonstrates the approvability of our core gel platform while emphasizing the flexibility of our technology in the key therapeutic area of womens health, commented Jack E. Stover, President & CEO.

Our development licensee for this product, BioSante Pharmaceuticals Inc., recently announced they had met with FDA representatives from the Division of Reproductive and Urologic Products, the Division of Cardio-Renal Products and the Office of Biometrics III (statistics) earlier this summer. The primary focus of the meeting was the safety study protocol to evaluate the cardiovascular risk of using testosterone in women, a key pre-approval concern of the FDA. It was reported that in addition to two Phase III efficacy trials, a separate Phase III cardiovascular safety study will also need to be conducted. The safety study will be a randomized, double-blind, placebo-controlled, multi-center, cardiovascular events driven study of between 2,400 and 3,100 women exposed to the low-dose testosterone or placebo for 12 months. A new drug application (NDA) can be filed and reviewed by the FDA, possibly leading to approval at that time. After NDA submission and potential approval the women enrolled in the study will be followed for an additional four years.

The Antares portfolio currently includes three womens health/urology products in clinical trials and one FDA approved product. Anturol ATD gel is for the treatment of overactive bladder (OAB) is in Phase III, a nestorone/estradiol low-dose ATD gel contraceptive is in Phase I and the low-dose testosterone ATD gel for Female Sexual Dysfunction (FSD) (mentioned above) is now in Phase III. The fourth product in this important therapeutic class is Elestrin which was approved by the FDA late last year and launched this past June.

Currently there is no FDA approved pharmaceutical product to treat FSD, and if approved, this product may help address the unmet medical need. It should be noted further that Intrinsa®, a testosterone patch developed and marketed by Procter & Gamble was approved for FSD in Europe and has been launched to date in the United Kingdom, France and Germany. According to a study published in the Journal of the American Medical Association, 43 percent of American women (about 40 million) experience some degree of impaired sexual function and it is anticipated that the size of the European market is approximately the same as the US. The overall market potential for low-dose testosterone products for FSD has been estimated to range from between $2 billion to $5 billion.

Advanced Transdermal Delivery Systems (ATD)

The ATD drug delivery platform is dedicated to the development of gels that offer a cosmetically superior option to patches, while delivering medication efficiently with less potential for skin irritation, minimizing gastrointestinal impact, as well as, the first-pass liver metabolism effect of many orally ingested drugs. Antares ATD gels are hydro-alcoholic and contain a combination of permeation enhancers to promote rapid drug absorption through the skin following application typically to the arms, shoulders, abdomen or thighs. The Companys transdermal ATD gel system provides the options for delivering both systemically (penetrating into and through the subcutaneous tissues and then into the circulatory system) as well as locally (e.g. topically for skin and soft tissue injury, infection and local inflammation). Typically, the gel is administered daily, and is effective on a sustained release basis over approximately a 24-hour period of time.
