Pfizer Inc. announced results published in The Lancet from the largest clinical trial of approved smoking cessation medicines, called EAGLES (Evaluating Adverse Events in a Global Smoking Cessation Study). This smoking cessation trial included 8,144 adult smokers and was designed to compare the neuropsychiatric safety of CHANTIX®/CHAMPIX® (varenicline) and bupropion with placebo and nicotine patch in adult smokers with and without a history of psychiatric disorders. The authors concluded that the trial did not show a significant increase in the incidence of the composite primary safety endpoint of serious neuropsychiatric adverse events with CHANTIX/CHAMPIX or bupropion compared to placebo and nicotine patch. Differences between incidence rates were considered significant if their associated 95% confidence intervals (CIs) were entirely above or below zero. Approximately half of the trial participants had a history of psychiatric disorders, either past and in remission or present and clinically stable. The psychiatric diagnoses included primarily depressive, bipolar, anxiety and psychotic disorders.
