Atrix Laboratories, Inc. (ATRX) Updates Eligard Prostate Cancer Products In Latin America

10/19/2005 5:11:34 PM

FORT COLLINS, Colo., June 1 /PRNewswire-FirstCall/ -- Atrix Laboratories, Inc. announced today that Tecnofarma International Ltd., Atrix's Latin America licensee, received marketing authorization from the Mexican regulatory authorities for the company's one- and three-month prostate cancer products. Eligard 7.5mg (leuprolide acetate for injectable suspension) one-month prostate cancer product was launched in May. Eligard(R) 7.5mg and 22.5mg (leuprolide acetate for injectable suspension) are indicated for the palliative treatment of hormone sensitive advanced prostate cancer.

"We estimated the private market in Mexico to be approximately $4 million. However, regardless of the size of the market, it is our goal to make Eligard a global product and give access to this new treatment option for prostate cancer patients around the world," said Michael R. Duncan, Atrix's vice president and general manager.

Additionally, Tecnofarma has submitted for marketing authorizations in Peru, Venezuela, Bolivia, Chile and in other countries of the region. Tecnofarma currently markets Eligard in Argentina. The estimated total market for hormone therapies like Eligard is approximately $3.3 million.

In 2002, Tecnofarma entered into a supply agreement for Eligard in Latin America including Mexico. Atrix will manufacture the products in its Fort Collins, Colorado facility. Tecnofarma is a privately held company that develops, manufactures, and markets a wide range of pharmaceutical products. The company has a sales force of over 1,200 sales representatives covering 16 countries throughout Latin America and focuses on several therapeutic areas including oncology and urology.

Leuprolide acetate is a lutenizing hormone releasing hormone (LHRH) agonist. Sustained levels of leuprolide acetate decrease testosterone levels to suppress tumor growth in patients with hormone-responsive advanced prostate cancer. The liquid Eligard product, using Atrix's proprietary Atrigel(R) sustained-release drug delivery technology, is injected subcutaneously with a small gauge needle, forming a solid implant in the body that slowly releases leuprolide as the implant is bioabsorbed.

Eligard products, like other hormonal treatments for prostate cancer, cause a transient increase in serum concentrations of testosterone during the first week of treatment. Patients may experience worsening of symptoms or onset of new signs and symptoms during the first few weeks of treatment. Response to these products should be monitored by measuring serum concentrations of testosterone and prostate specific antigen periodically.

Atrix Laboratories, Inc. is an emerging specialty pharmaceutical company focused on advanced drug delivery. With unique sustained release and topical technologies, Atrix is currently developing a diverse portfolio of proprietary products, including oncology, pain management, and dermatology products. The company also partners with large pharmaceutical and biotechnology companies to apply its proprietary technologies to new chemical entities or to extend the patent life of existing products.
