Forest Laboratories, Inc. and Almirall, S.A. announced today that the U.S. Food and Drug Administration (FDA) has approved Tudorza™ Pressair™ for the long-term maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.
COPD is a common, progressive, and debilitating lung disease characterized by persistent airflow limitation that makes it hard to breathe; it is currently the third leading cause of mortality in the US1. Characteristic symptoms include breathlessness, excessive production of sputum, and a chronic cough.
Tudorza™ is a twice-daily inhaled long-acting anticholinergic, also referred to as a long-acting muscarinic antagonist (LAMA). Tudorza produces bronchodilation by inhibiting acetylcholine’s effect on muscarinic receptors in the airway smooth muscle. Forest expects Tudorza Pressair to be available to wholesalers in the fourth calendar quarter of 2012.
“We are pleased with the FDA approval of Tudorza. As the first long-acting inhaled anticholinergic agent approved in over 8 years for COPD, Tudorza will be an important treatment option available for the millions of patients living with this serious disease. Tudorza’s approval marks an important milestone in our ongoing partnership with Almirall and advances Forest’s respiratory franchise and our commitment to COPD patients,” commented Howard Solomon, Chairman, Chief Executive Officer, and President of Forest Laboratories commented.
“The FDA approval of TudorzaTM PressairTM demonstrates our steadfast commitment to the development of respiratory compounds, such as aclidinium, innovative delivery devices, and our unfailing belief in their potential for the treatment of COPD. Today, we celebrate this achievement for our company and, most importantly, for the patients we serve,” commented Jorge Gallardo, President of Almirall.
Professor Richard Casaburi, MD, Associate Chief for Research in the Division of Respiratory and Critical Care Physiology and Medicine, Harbor-UCLA Medical Center, stated, “The Global Initiative for Chronic Obstructive Lung Disease 2011 guidelines recommend long-acting anticholinergics as a first-line therapy for a broad range of COPD patients with moderate to very severe disease. Tudorza will be a valuable anticholinergic option in the clinical armamentarium available to manage this serious disease.”
Data Highlights
The Tudorza Pressair clinical development program included a dose-ranging trial and 3 confirmatory pivotal trials. The two 12-week and one 24-week pivotal placebo-controlled trials evaluated the efficacy and safety of Tudorza 400 mcg twice daily in 1,276 patients. Patients enrolled in these trials had a clinical diagnosis of COPD, were 40 years of age or older, had a smoking history of at least 10 pack-years, a forced expiratory volume in one second (FEV1) of at least 30% and less than 80% of predicted normal value, and a ratio of FEV1 over forced vital capacity (FEV1/FVC) of less than 0.7.
In all 3 pivotal trials, Tudorza Pressair demonstrated statistically significant improvements in bronchodilation, as measured by change from baseline in morning pre-dose trough FEV1 at 12 weeks (the primary endpoint) compared to placebo. The mean 12-week pre-dose FEV1 improvements vs placebo were 0.12 L, 0.07 L, and 0.11 L in the 3 trials, with a 24-week improvement of 0.13 L in the 6-month trial. Mean peak improvements in lung function (FEV1) assessed after the first dose of Tudorza were similar to those observed at week 12 in each study. Tudorza had a low incidence of side effects in these trials.
The most common adverse reactions that occurred in the Tudorza Pressair group with a frequency of greater than or equal to 3% and exceeding placebo were headache (6.6% vs 5.0%), nasopharyngitis (5.5% vs 3.9%), and cough (3.0% vs 2.2%). Three long-term safety studies, evaluating 891 patients treated with Tudorza Pressair 400 mcg twice daily for 40 to 52 weeks reported similar adverse events, with no new safety findings compared to the placebo-controlled trials.
Additionally, serial spirometric evaluations of FEV1 were performed over 12 hours in a subset of patients in the three pivotal trials. Improvement of lung function with TUDORZA PRESSAIR versus placebo was achieved for the first 12 hours on day 1 and was consistent over the 3- or 6-month treatment period evaluated.
In two of the three trials, patients treated with Tudorza Pressair also used less daily rescue albuterol compared to placebo treated patients.
About Tudorza Pressair
Tudorza Pressair (aclidinium bromide inhalation powder) 400 mcg is an anticholinergic indicated for the long-term maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. When given by inhalation, aclidinium produces bronchodilation by inhibiting the muscarinic M3 receptor in the airway smooth muscle. Aclidinium is rapidly hydrolyzed in human plasma into two major inactive metabolites.
Tudorza is administered using a multiple-dose dry powder inhaler, Pressair, which delivers 60 doses of aclidinium bromide powder for inhalation. The Pressair inhaler has a colored control window and audible “click” which confirm successful inhalation of the dose and a dose indicator to let patients know how many doses remain in the inhaler.
In 2005, Forest Laboratories, Inc. licensed U.S. rights for aclidinium from Almirall, while Kyorin Pharmaceutical Co., Ltd holds marketing rights in Japan and Daewoong Pharmaceutical Co., Ltd is licensed to market aclidinium in Korea. Almirall has recently given rights of joint commercialization in the majority of European member states and a number of non-EU countries to Menarini. Almirall maintains rights for the rest of the world.
About COPD
COPD, or chronic obstructive pulmonary disease, is a common, progressive, and debilitating lung disease characterized by persistent airflow limitation that makes it hard to breathe. 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. WHO predicts that COPD will become the third leading cause of death worldwide by 2030. COPD is already the third leading cause of death in the U.S.
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 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. New therapies to treat this debilitating disease may be of value.
Important Safety Information
Tudorza Pressair is not indicated for the initial treatment of acute episodes of bronchospasm (i.e., rescue therapy). Inhaled medicines, including Tudorza, may cause paradoxical bronchospasm. If this occurs, treatment with Tudorza should be stopped and other treatments considered.
Tudorza should be used with caution in patients with narrow-angle glaucoma or urinary retention. Instruct patients to consult a physician immediately should any signs or symptoms of narrow-angle glaucoma or prostatic hyperplasia or bladder-neck obstruction develop.
Immediate hypersensitivity reactions may occur after administration of Tudorza. If such a reaction occurs, therapy with Tudorza should be stopped at once and alternative treatments considered. Patients with a history of hypersensitivity reactions to atropine should be closely monitored for similar hypersensitivity reactions to Tudorza. Use with caution in patients with severe hypersensitivity to milk proteins.
