FDA approves Cayston® (aztreonam for inhalation solution) for P. aeruginosa in CF patients

First New Inhaled Anti-Pseudomonal Therapy Approved for Cystic Fibrosis Patients in More Than 10 Years
FOSTER CITY, Calif., Feb 22, 2010 (BUSINESS WIRE) -- Gilead Sciences, Inc. (Nasdaq:GILD) today announced that the U.S. Food and Drug Administration (FDA) has granted marketing approval for Cayston® (aztreonam for inhalation solution) as a treatment to improve respiratory symptoms in cystic fibrosis (CF) patients with Pseudomonas aeruginosa (P. aeruginosa). Cayston's safety and efficacy have not been established in pediatric patients below the age of 7, patients with forced expiratory volume in one second (FEV1) of less than 25 percent or greater than 75 percent predicted, or patients colonized with Burkholderia cepacia.

Cayston is administered at a dose of 75 mg three times daily over a 28-day period and is delivered via the Altera® Nebulizer System, a portable, drug-specific delivery device using the eFlow® Technology Platform, developed by PARI Pharma GmbH. PARI Pharma also contributed to the development of Cayston's drug formulation for delivery with the Altera Nebulizer System. Cayston will be available in the United States by the end of next week through certain specialty pharmacies.

"All of us at Gilead extend our thanks to the investigators and to the people with cystic fibrosis who took part in the Cayston clinical trials," said Norbert Bischofberger, PhD, Gilead's Executive Vice President, Research and Development and Chief Scientific Officer. "We look forward to making Cayston available to the cystic fibrosis community as soon as possible."

CF is a chronic, debilitating genetic condition that affects the respiratory and digestive systems of approximately 70,000 people worldwide, including 30,000 people in the United States. Chronic respiratory tract infection with P. aeruginosa contributes to the decline in pulmonary function, which is often associated with morbidity and mortality among CF patients.

"Since its founding in the 1950s, the Cystic Fibrosis Foundation has worked to advance the care and treatment of cystic fibrosis and we are pleased with the progress to date," said Robert J. Beall, PhD, President and Chief Executive Officer, Cystic Fibrosis Foundation. "However, a significant need for new treatments remains for people with cystic fibrosis, particularly for those with chronic pseudomonal infection. As the first new inhaled antibiotic approved for use in cystic fibrosis in more than a decade, Cayston therefore represents an important therapeutic option in the care of patients with cystic fibrosis."

Cayston received conditional marketing authorizations in the European Union and Canada in September 2009 and was approved in Australia in January 2010. Applications for marketing approval of Cayston are currently pending in Switzerland and Turkey.

Reimbursement and Access to Care

Gilead also announced today the establishment of a program designed to minimize barriers to access for Cayston for uninsured, privately insured and government-insured people with cystic fibrosis.

Additionally, Gilead is launching the Cayston® Access Program, a call center developed with Cystic Fibrosis Foundation Pharmacy, LLC,a wholly owned subsidiary of the Cystic Fibrosis Foundation. The program will assist people with cystic fibrosis and members of their care team with insurance verification, referral to participating specialty pharmacies, claims support and co-pay assistance.
