Anacor Pharmaceuticals, Inc. To Present Efficacy Results On Lead Drug Candidates

PALO ALTO, Calif. and PARIS, Sept. 7 /PRNewswire/ -- Anacor Pharmaceuticals, a privately held pharmaceutical company, today announced it will present six posters at the European Society for Dermatological Research Meeting in Paris this week, including interim results from a 60-patient open-label trial of AN2690, its topical antifungal drug candidate being developed for onychomycosis, a fungal infection of the toenail and nail bed. Halfway through the six-month, Phase 2 trial, no nail samples were dermatophyte-positive, and 67 percent of subjects had sufficient clear nail growth to be considered responders. A separate presentation at the meeting will detail a second study of 15 patients receiving AN2690 that shows levels of the drug in the bloodstream are below the level of quantification and that no patients in that trial had a positive fungal culture after four weeks.

"These and other results strongly suggest that AN2690 could be the first topical treatment for onychomycosis with efficacy that is comparable to oral treatments," said Dr. Karl Beutner, chief medical officer at Anacor. "In addition, our clinical work has shown the drug appears to be free of systemic side effects."

Anacor researchers will also present data from the development program for AN0128, Anacor's treatment for atopic dermatitis. Results from a 103-patient Phase 2a study show that 51 percent of patients treated with AN0128 were judged to have skin that was "clear" or "almost clear," as compared with 37 percent of patients treated with the vehicle treatment, and an analysis of patients with more severe disease found an even greater difference between AN0128 and the vehicle cream.
