Forest and Almirall Announce Submission of New Drug Application for Aclidinium Bromide for the Treatment of Chronic Obstructive Pulmonary Disease (COPD)

Forest Laboratories, Inc. (NYSE: FRX) and Almirall, S.A. (ALM.MC) announced they have recently submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for aclidinium bromide, a long-acting inhaled antimuscarinic agent developed for the treatment of COPD.

The submission includes efficacy data from a large Phase III double-blind placebo-controlled program in which patients received aclidinium bromide 400 mcg or 200 mcg twice daily or placebo. In the pivotal studies, aclidinium 400 mcg twice-a-day, the proposed to-be-marketed dose, produced significant improvement in morning trough FEV₁ versus placebo at week 12 (p<0.0001), the primary endpoint assessed as support for the U.S. NDA, and at week 24 (p<0.0001), which was the primary endpoint assessed in one study as support for a European filing.

Additionally, safety data collected from the Phase III program demonstrated that aclidinium 400 mcg twice-a-day was generally well tolerated, with an incidence of adverse events that was low and similar across the study treatment arms. The most commonly reported adverse reactions were headache and nasopharyngitis.

About aclidinium bromide

Aclidinium bromide is a novel, long-acting inhaled anitmuscarinic agent, which is often referred to as an anticholinergic, that has a long residence time at M3 receptors and a shorter residence time at M2 receptors. When given by inhalation, aclidinium leads to bronchodilation by inhibiting airway smooth muscle contraction. Aclidinium is rapidly hydrolyzed in human plasma to two major inactive metabolites. Forest Laboratories, Inc. licensed U.S. rights for aclidinium from Almirall, while Almirall maintains rights for the rest of the world. The companies are jointly involved in the development of the compound.

Aclidinium bromide was administered to patients in the trials using a novel, investigational, state-of-the-art multidose dry powder inhaler (MDPI). This inhaler was designed with a feedback system which, through a 'colored control window' and an audible click, helps confirm that the patient has inhaled correctly. It contains multiple doses of aclidinium, includes a visible dose-level indicator and also incorporates safety features such as an anti-double-dosing mechanism and an end-of-dose lock-out system to prevent use of an empty inhaler.

About COPD

The World Health Organization (WHO) has described COPD as a global epidemic; an estimated 64 million people have COPD worldwide. More than 3 million people died of the condition in 2005, which is equal to 5% of all deaths globally that year. Total deaths from COPD are projected to increase by more than 30% in the next 10 years without interventions to cut risks, particularly exposure to tobacco smoke.

In patients with COPD the airways in the lungs typically lose their elasticity, produce excess mucus and become thick and inflamed, limiting the passage of air. The most common symptoms of COPD are breathlessness (or a "need for air"), abnormal sputum (a mix of saliva and mucus in the airway), and a chronic cough. Daily activities, such as walking up a short flight of stairs or carrying a suitcase, can become very difficult as the condition gradually worsens. There are significant unmet needs in the treatment of COPD and new therapies may be of value.
