Exhibit 99.1



New Pilot Clinical Study Results Demonstrate that Addition of VIVUS’ Qsymia® to Gastric Sleeve Surgery Significantly Improves Weight Loss Compared with Surgery Alone


-Data published in Surgery for Obesity and Related Diseases also show that patients in the Qsymia group lost more than twice as much weight during preoperative treatment compared with control group-


CAMPBELL, CA., August 20, 2019 — VIVUS, Inc. (NASDAQ: VVUS; the “Company”) today announced the results of a pilot clinical study demonstrating that patients receiving Qsymia (phentermine and topiramate extended-release (ER)) capsules CIV before and after laparoscopic sleeve gastrectomy (LSG) surgery lost more weight and had a greater probability of achieving a body mass index (BMI) of less than 40 compared with patients undergoing surgery alone without anti-obesity medication (AOM). The study was conducted at the Wake Forest School of Medicine and the results appear in the current issue of Surgery for Obesity and Related Diseases.


“Patients with a BMI of 50 or greater generally benefit from bariatric surgery but have higher surgical risk and increased perioperative morbidity compared with patients with lower BMI,” said Jamy Ard, MD, Professor, Epidemiology and Prevention at Wake Forest School of Medicine and lead author on the publication. “In an effort to reduce these risks, we undertook a pilot study to assess the feasibility and impact of using the drug before and after LSG surgery. Study results show that patients taking it lost significantly more weight before surgery and had improved outcomes with respect to weight loss and BMI than those not on AOM. This may allow more patients to avoid a secondary surgical procedure and its attendant risks. These results should be further evaluated in larger studies.”


In addition to increased surgical risk, patients with a BMI of 50 or greater are likely to have a BMI of 40 or greater even after successful surgery. Physicians often address this issue by offering patients a two-stage weight loss process that involves an initial LSG followed by a second surgical procedure after initial post-LSG weight loss. Treatments that allow patients to achieve BMI of less than 40 after the initial LSG could reduce the need for a second surgical procedure, decreasing health risks and costs. “Though there is no consensus from a guidelines perspective, the use of the AOM Qsymia with a low-calorie diet prior to LSG has the potential to decrease weight and reduce surgical risk, while post-LSG Qsymia use could increase and maintain the total amount of weight lost with the potential to eliminate the need for a second surgical procedure,” said Santosh T. Varghese, MD, Chief Medical Officer at VIVUS.



The pilot study recruited 25 participants with a BMI of 50 or more who were planning to undergo LSG. Patients in the control group had a BMI of 50 or more and underwent LSG in the same timeframe (June 2014 — July 2016) but were not included in the study protocol. Patients in the experimental arm received Qsymia at a dose of 3.75/23 mg once daily for two weeks, which was then increased to 7.5/46 mg or 15/92 mg daily in order to achieve the greatest weight loss with the fewest side effects. Patients tapered off the medication beginning two weeks prior to surgery in order to avoid potential interactions between phentermine and anesthesia and resumed dosing at 7.5/46 mg daily one month following LSG, with dose adjustments made monthly over the next two months. Patients then continued to utilize Qsymia for a 24-month period.


Key findings from the study include:


·                  The experimental group had a baseline BMI of 61.2 ± 7.1 kg/m2 compared with 57.0 ± 5.6 kg/m2 for control participants. At 24 months, the mean BMI was 33.8 kg/m2 for the experimental group vs. 42 kg/m2 for control participants.

·                  Of the 25 patients recruited, 13 completed LSG. Patients who did not complete LSG were due to: medical complications unrelated to Qsymia (n=2), decision not to pursue surgery (n=1), Qsymia-related adverse events (n=3), because they were lost to follow-up and withdrawn from the study (n=4) or opted to undergo a surgical procedure other than LSG (n=2).

·                  Patients in the experimental arm lost more than twice the weight with an average of 28.1 kg during the pre-operative period compared with an average of 12.3 kg for those in the control group.

·                  At two years post-LSG, the experimental group lost 11.2% more of initial body weight compared with controls (p=0.007), which translates to a -18.2% difference in percent excess weight loss (%EWL) of favoring the experimental group.

·                  A higher proportion of patients in the experimental group compared with controls achieved a BMI less than 40 at 3, 6, 12 and 24 months post-LSG (61.5% vs. 47.5% at 24 months, respectively).

·                  There was a significant increase in the odds of achieving BMI less than 40 for the experimental group compared with controls at 6 months post-LSG (odds ratio = 4.1); at 24 months the odds ratio remained 4.1 but was no longer statistically significant.


The study authors conclude that for patients with a BMI of 50 or more the combination of LSG and phentermine/topiramate ER (Qsymia) had a robust impact on patients both before and for up to two years after LSG surgery.


“This pilot study adds to the growing body of data supporting the use of Qsymia in a variety of therapeutic strategies for helping adults with obesity improve their BMI and achieve more healthy weight goals,” said John Amos, Chief Executive Officer at VIVUS.  “The potential to help these patients achieve a BMI less than 40 and potentially avoid the need for a second surgical procedure would be an important advance in improving outcomes while reducing risk. Additionally, the enhanced pre-LSG weight loss in the experimental group compared with controls further underscores the clinical benefit that Qsymia can provide even in patients with a BMI of 50 or more.”



About Qsymia


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.


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; 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.
