VIVUS, Inc on 7. January 201, announced positive results from a phase 2 study evaluating the safety and efficacy of Qnexa®, an investigational drug, for the treatment of obstructive sleep apnea (OSA). VIVUS recently completed phase 3 development of Qnexa for the treatment of obesity and submitted a New Drug Application (NDA) to the FDA for that indication. The OSA- study announced demonstrated statistically significant improvement in the apnea/hypopnea index ("AHI" - a measure of the severity of sleep apnea) in patients with OSA treated with Qnexa for 28 weeks.
OSA is a sleep-related breathing disorder that involves a decrease or complete halt in airflow despite an ongoing effort to breathe. OSA is associated with an increased risk of hypertension, diabetes, stroke, sudden cardiac death and all-cause mortality. Currently, there are no approved pharmacologic treatments for OSA and current treatment approaches are limited to devices or surgery, so if approved by the FDA, Qnexa® not only reduce the weight but also significantly improve sleep apnea.
