About the Sleep Apnea (OB-204) Study

The phase 2 study (OB-204) was a single-center, randomized, double-blind, placebo-controlled parallel group trial including obese men and women (BMI 30 to 40 kg/m2 inclusive), 30 to 65 years of age with OSA (apnea/hypopnea index greater than or equal to 15) at baseline, who had not been treated with, or who were not compliant with continuous airway pressure (CPAP) devices within three months of screening. Patients were randomized to placebo or full-dose Qnexa. Patients underwent a four-week dose titration followed by 24 weeks of additional treatment. All patients were also provided with a lifestyle modification program focusing on diet and exercise. Overnight polysomnography was performed at baseline, Week 8 and Week 28. The primary endpoint was the change in Apnea/Hypopnea Index (AHI) between baseline and Week 28; secondary endpoints included weight loss, oxygen saturation and changes in blood pressure.

About Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea (OSA) is a sleep-related breathing disorder that involves a decrease or complete halt in airflow despite an ongoing effort to breathe. Approximately 18 million Americans are living with OSA, though an estimated 90 percent of patients remain undiagnosed or untreated. Studies have identified a relationship between OSA and a number of cardiovascular and metabolic diseases including hypertension, diabetes, stroke, congestive heart failure and sudden cardiac death. Currently, there are no pharmacotherapy agents approved to treat sleep apnea. More information on sleep apnea can be found on the American Academy of Sleep Medicine website at:
