‘Smoker’s cough’ drug succeeds in late-stage trials, Novartis says
Four more trials will be completed this year, to prepare for United States Food and Drug Administration approval, as well as that of European and Japanese drug regulators.
Caused mainly by tobacco smoking, air pollution or job exposure to lung hazards, chronic obstructive pulmonary disease (COPD) — known commonly as smoker’s cough — is painful and debilitating. It forces its sufferers to cough most of the time, to take painful breaths, and to fall into debilitating bouts of breathlessness.
Chronic bronchitis and emphysema — over-inflation of the air sacs or alveoli in the lungs — are common symptoms that progress slowly and in time, lead to an irreversible loss of lung function. Around three-fourths of patients with advanced COPD are unable to perform normal everyday activities — and a good number of them go on to die when their lungs collapse.
According to National Institutes of Health, more than 12 million Americans are diagnosed with COPD, and another 12 million probably have it but don’t know. Across the world, about 210 million people have COPD. Every year, COPD claims the lives of 120,000 Americans.
Currently the fourth most common cause of death worldwide, by 2020 it’s predicted to become the third most common cause of death and top four disability-causing illness. In Europe, the total financial burden of lung disease amounts to nearly EUR102 billion — with COPD contributing almost one-half to these costs.
A 2011 study in the journal BMC Public Health revealed the actual impact of COPD on global productivity. It showed that while the ailment is often thought of as a disease of the elderly, a half of all COPD patients are within the ages of 50 and 65 — at the ages when they are likely at the peak of their earning power and family responsibilities.
Because tobacco smoking and other forms of consumption is the main cause of COPD, the prevalence of the disease will increase over the next 20 years in the U.S. and Europe, but it’s expected to plateau after that. But in Japan, China and other parts of Asia, where almost half of all men smoke and smoking rates continue to rise, COPD is expected to keep increasing for more than 40 years.
Experimental COPD drug meets goals
Fortunately, a new experimental treatment for patients with COPD has met the main goals of three late- stage clinical trials, its maker Swiss pharmaceutical Novartis announced on April 2. This means that it’s closer to being approved by drug regulators in the U.S., Canada, Europe, Japan and across the world.
The new medication, QVA149, is a combo drug that mixes two older Novartis lung drugs:
• The long-acting beta2-agonist (LABA) sold as Arcapta Neohaler — chemically known as indacaterol and sold in Europe as Onbrez Breezhaler
• The long-acting muscarinic antagonist (LAMA) sold as Seebri Breezhaler (NVA237) — chemically known as glycopyrronium bromide
Both drugs have been approved in some countries for COPD.
QVA149 contains 110 mcg of indacaterol and 50 mcg of glycopyrronium bromide and is inhaled once a day.
The first trial — called SHINE — showed that a once daily dose of QVA149 was better than the equivalent dose of Onbrez and NVA237 taken individually. This trial was a 26-week, multicenter, randomized, double-blind, parallel-group, placebo and active controlled pivotal trial of 2,144 patients with moderate to severe COPD.
A second trial — named BRIGHT — showed patients taking QVA149 had exercise endurance that was a significantly better than those taking a placebo. This was a smaller study of 85 patients with moderate or severe COPD. BRIGHT was a three-week, randomized, blinded, double-dummy, multi-center, placebo controlled, three-period crossover pivotal trial.
