Acrux (ASX: ACR), the pharmaceutical company with unique technology for delivering drugs through the skin, today announced positive results in a US Phase 3 clinical trial of Evamist, its daily skin spray for prevention of symptoms associated with menopause. The trial was conducted by its US commercial partner VIVUS Inc. (NASDAQ: VVUS), which will now proceed to file a marketing application with the US Food and Drug Administration (FDA) in the second half of 2006.

Evamist is the most advanced commercial application of Acrux's patented delivery technology; if the FDA approves VIVUS' marketing application, Acrux's first product could be available to women in the USA in the second half of 2007. Several other products that use the same delivery technology are following close behind. The positive result of this Phase 3 trial is therefore a pivotal milestone for each of these products.

The Phase 3 trial assessed the safety and efficacy of Evamist for the treatment of hot flushes in menopausal women. The trial was a 12-week study of 457 menopausal women, conducted under a Special Protocol Assessment (SPA) from the FDA. Results showed that the most effective Evamist dose decreased the number of hot flushes by 78%. The reduction in frequency and severity of moderate to severe hot flushes was statistically significant compared with placebo for all three doses of Evamist evaluated.

Importantly, application site irritation was less than 1% and was mild in nature. The results from the trial will be discussed by VIVUS at an Analyst Day in New York on 18 May 2006.

"We believe these positive trial results along with this novel patient-preferred transdermal delivery system will establish Evamist as a superior estrogen therapy for the treatment of menopausal symptoms," stated Leland Wilson, president and chief executive officer for VIVUS. "We have worked diligently toward the development of this unique and easy-to-use product, and we are thrilled with
