FDA Accepts Qnexa NDA
VIVUS Announces FDA Acceptance of Qnexa New Drug Application for Treatment of Obesity
MOUNTAIN VIEW, Calif., March 1 /PRNewswire-FirstCall/ -- VIVUS, Inc. today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing the company's new drug application (NDA) for its investigational drug, Qnexa, for the treatment of obesity. The target date for the FDA to complete its review of the Qnexa NDA is October 28, 2010. In previously announced pivotal phase 3 trials, patients treated with all three doses of Qnexa achieved significant weight loss compared to placebo, and significant dose-related improvements in a variety of secondary endpoints including reductions in cardiovascular, inflammatory and metabolic risk factors.
"The FDA's acceptance of the Qnexa NDA marks an important milestone in the development of Qnexa as a treatment for patients who are obese or overweight with co-morbidities," stated Leland F. Wilson, chief executive officer for VIVUS. "We believe that Qnexa, if approved, will play an important role in treating the millions of patients living with obesity and related diseases, and who are in need of safe and effective options."
About the Phase 3 Obesity Program
The phase 3 clinical program, which evaluated Qnexa in more than 4,500 patients, was designed under a Special Protocol Assessment with the U.S. FDA and consisted of three trials: EQUATE (OB-301), EQUIP (OB-302) and CONQUER (OB-303). The EQUATE study was a 28-week randomized, double-blind, placebo-controlled, 7-arm, prospective trial with patients randomized to receive once-a-day treatment with mid- or full-dose Qnexa, the respective phentermine and topiramate constituents, or placebo. The average baseline BMI of the study population was 36.3 kg/m2 with an average baseline weight of 223 pounds. The EQUIP and CONQUER studies were 56-week, randomized, double-blind, placebo-controlled, 3-arm, prospective trials with patients randomized to receive once-a-day treatment with low-, mid-, or full-dose Qnexa, or placebo. In EQUIP, the average baseline BMI of the study population was 42.1 kg/m2 with an average baseline weight of 256 pounds; in CONQUER, the average baseline BMI of the study population was 36.6 kg/m2 with an average baseline weight of 227 pounds. All patients were asked to follow a hypocaloric diet representing a 500-calorie/day deficit and advised to implement a simple lifestyle modification program.
Qnexa (Q-NEX-uh) is an investigational drug being developed to address weight loss. Qnexa is a once-a-day, proprietary, oral, controlled-release formulation of low dose phentermine and topiramate, which is believed to address both appetite and satiety - the two main mechanisms that impact eating behavior - in one capsule. In phase 2 and 3 clinical data to date, Qnexa has demonstrated significant weight loss, glycemic control, reduction in sleep apnea events and improvement in cardiovascular risk factors.
VIVUS is a biopharmaceutical company developing innovative, next-generation therapies to address unmet needs in obesity, diabetes and sexual health. The company's lead product in clinical development, Qnexa, has recently completed phase 3 clinical trials for the treatment of obesity. Qnexa is also in phase 2 clinical development for the treatment of type 2 diabetes and obstructive sleep apnea (OSA). In the area of sexual health, VIVUS is in phase 3 development with avanafil, a potentially best-in-class PDE5 inhibitor, and in phase 2 development of Luramist™ for the treatment of hypoactive sexual desire disorder (HSDD) in women. MUSE (alprostadil), a first generation therapy for the treatment of ED, is already on the market and generating revenue for VIVUS.
