New Clinical Data Demonstrate VIVUS' Qsymia® is Effective at Reducing Binge Eating in Patients with Binge-Eating Disorder or Bulimia Nervosa
-Data published in International Journal of Eating Disorders show patients in the Qsymia group had 75% decrease in binge day frequency compared with 19% for placebo-
CAMPBELL, Calif., Nov. 20, 2019 (GLOBE NEWSWIRE) -- VIVUS, Inc. (Nasdaq: VVUS) (the “Company”), a biopharmaceutical company, today announced the results of a clinical study (NCT02553824) demonstrating that patients with binge-eating disorder (BED) or bulimia nervosa (BN) receiving Qsymia (phentermine and topiramate extended-release (ER)) capsules CIV had a significant reduction in binge day frequency compared with placebo over four weeks. Additionally, Qsymia was well tolerated in these patient populations. The study results appear online in the International Journal of Eating Disorders.
"Dropout rates for the two pharmacologic therapies approved for BED and BN range from 20 to 30 percent and many patients using these medications remain symptomatic, underscoring the need for alternative therapeutic approaches," said Santosh T. Varghese, MD, Chief Medical Officer at VIVUS. "The promising results announced today, along with previously reported data from another study evaluating Qsymia in BED, suggest that Qsymia could address an unmet treatment need in BED and BN and support further investigation of Qsymia as a treatment option for these serious medical conditions."
The randomized, double blind, placebo-controlled, crossover study enrolled 22 patients (BED=18 and BN=4) who were randomized to Qsymia (n=12, 3.75/23 mg phentermine [PHEN]/topiramate [TPM]-ER – 15 mg PHEN/92 mg TPM-ER) or placebo (n=10) for 12 weeks. The mean baseline body mass index for the 22 was 31.1 kg/m2. Following a two-week washout, patients crossed over to the other arm for 12 weeks. The primary outcome was the number of objective binge-eating (OBE) days over four weeks; secondary outcomes included binge abstinence. Demographics, vital signs, eating disorder behaviors, mood and side effect data were also collected.
Key findings from the study include:
Qsymia is approved in the United States and is indicated as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with an initial body mass index (BMI) of 30 kg/m2 or greater (obese) or 27 kg/m2 or greater (overweight) in the presence of at least one weight-related medical condition such as high blood pressure, type 2 diabetes, or high cholesterol.
The effect of Qsymia on cardiovascular morbidity and mortality has not been established. The safety and effectiveness of Qsymia in combination with other products intended for weight loss, including prescription and over-the-counter drugs, and herbal preparations, have not been established.
