MOUNTAIN VIEW, Calif., Feb. 1, 2013 /PRNewswire/ --VIVUS, Inc. (Nasdaq: VVUS)
announced today the publication of a study concluding that weight loss
resulting from treatment with Qsymia^TM (phentermine and topiramate
extended-release) capsules CIV led to significant improvements in cholesterol,
blood pressure and triglycerides in obese and overweight patients experiencing
one or more of these associated conditions. The improvements were
significantly greater among patients who lost 10% or more of their starting
weight.

The study was published online in The American Journal of Cardiology and can
be accessed via the following link:

"This provides clear evidence that patients with hypertension or high
cholesterol treated with Qsymia for one year experienced significant weight
loss and clinically meaningful improvements in their underlying cardiovascular
risk factors," said Suzanne Oparil, M.D., Director of the Vascular Biology and
Hypertension Program, University of Alabama at Birmingham, and an investigator
in the study. "The ability to improve underlying risk factors is another
reason physicians should proactively discuss the medical treatment of obesity
with their patients who have failed lifestyle modification alone."

Obesity is a chronic condition defined by having excess body fat. Obesity and
smoking are the leading causes of preventable death in the U.S., and obesity
contributes directly to numerous life-threatening conditions including
diabetes, cardiovascular disease, hypertension and stroke. According to the
World Health Organization and CDC, more than 500 million people worldwide and
approximately one-third of American adults (more than 78 million people) are
obese. In addition to obesity, high cholesterol, blood pressure and
triglycerides are significant risk factors for cardiovascular disease.

About the Study
Participants in the study with body mass indexes of 27 to 45 kg/m^2 were
randomized to placebo, recommended dose (7.5/46mg) or top dose (15/92mg)
Qsymia. Participants also received lifestyle modification counseling. Primary
end points were percentage weight loss and the proportion of participants
achieving at least 5% weight loss. Additional end points were changes in lipid
variables in patients with dyslipidemia and changes in blood pressure in
patients with hypertension, stratified by treatment assignment and magnitude
of weight loss. Qsymia produced significantly greater dose-related mean
percentage weight loss compared with placebo in the subgroups of participants
with dyslipidemia and those with hypertension.

In the subgroup with dyslipidemia, treatment-emergent adverse events occurred
in 75.9%, 86.5%, and 88.3% of the placebo, recommended dose, and top dose
groups, respectively. In the subgroup with hypertension, the rates were 77.3%,
85.4%, and 88.8%, respectively. The most common treatment emergent adverse
events in the subgroup with dyslipidemia and the subgroup with hypertension
were dry mouth, paraesthesia, constipation, upper respiratory tract infection,
and nasopharyngitis. Adverse event profiles in these high risk patients were
similar to those seen in the study population as a whole.

About Qsymia
Qsymia is approved in the U.S. 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/m^2 or
greater (obese) or 27 kg/m^2 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.

Important Safety Information
Qsymia (phentermine and topiramate extended-release) capsules CIV is
contraindicated in pregnancy; in patients with glaucoma; in hyperthyroidism;
in patients receiving treatment or within 14 days following treatment with
monoamine oxidase inhibitors (MAOIs); or in patients with hypersensitivity to
sympathomimetic amines, topiramate, or any of the inactive ingredients in
Qsymia.

Qsymia can cause fetal harm. Females of reproductive potential should have a
negative pregnancy test before treatment and monthly thereafter and use
effective contraception consistently during Qsymia therapy. If a patient
becomes pregnant while taking Qsymia, treatment should be discontinued
immediately, and the patient should be informed of the potential hazard to the
fetus.

The most commonly observed side effects in controlled clinical studies, 5% or
greater and at least 1.5 times placebo, include paraesthesia, dizziness,
dysgeusia, insomnia, constipation, and dry mouth.
