MOUNTAIN VIEW, CA -- (Marketwired) -- 06/30/16 -- VIVUS, Inc.(NASDAQ: VVUS) (the "Company"), a biopharmaceutical company commercializing and developing innovative, next-generation therapies to address unmet needs in obesity and sexual health, today announced an extension of the termination date of the license agreement between Auxilium Pharmaceuticals, Inc., a subsidiary of Endo International, plc, and VIVUS for STENDRA^® (avanafil) U.S. and Canadian commercial rights through August 31, 2016. In December 2015, Auxilium notified VIVUS of its intention to return the U.S. and Canadian commercial rights for STENDRA. This notification was Auxilium's contractually required six-month notice of termination which, absent an agreement between Auxilium and the Company, would have resulted in the termination of the license agreement on June 30, 2016.

"As we have discussed, we and our advisor are engaged in a business evaluation process to optimize the value of STENDRA and Qsymia," said Seth H. Z. Fischer, VIVUS Chief Executive Officer. "We expect to make our decision on whether to commercialize STENDRA on our own or with a third party in the near term. The extension with Auxilium will provide us with additional time to ensure no interruptions in the availability of STENDRA to patients and health care providers while we complete our evaluation and process."

Important Safety Information

STENDRA^® (avanafil) is prescribed to treat erectile dysfunction (ED).

Do not take STENDRA if you take nitrates, often prescribed for chest pain, as this may cause a sudden, unsafe drop in blood pressure.

Discuss your general health status with your healthcare provider to ensure that you are healthy enough to engage in sexual activity. If you experience chest pain, nausea, or any other discomforts during sex, seek immediate medical help.

STENDRA may affect the way other medicines work. Tell your healthcare provider if you take any of the following; medicines called HIV protease inhibitors, such as ritonavir (Norvir^®), indinavir (Crixivan^®), saquinavir (Fortavase^® or Invirase^®) or atazanavir (Reyataz^®); some types of oral antifungal medicines, such as ketoconazole (Nizoral^®), and itraconazole (Sporanox^®); or some types of antibiotics, such as clarithromycin (Biaxin^®), telithromycin (Ketek^®), or erythromycin.

In the rare event of an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.

In rare instances, men taking PDE5 inhibitors (oral erectile dysfunction medicines, including STENDRA) reported a sudden decrease or loss of vision. It is not possible to determine whether these events are related directly to these medicines or to other factors. If you experience sudden decrease or loss of vision, stop taking PDE5 inhibitors, including STENDRA, and call a doctor right away.

Sudden decrease or loss of hearing has been rarely reported in people taking PDE5 inhibitors, including STENDRA. It is not possible to determine whether these events are related directly to the PDE5 inhibitors or to other factors. If you experience sudden decrease or loss of hearing, stop taking STENDRA and contact a doctor right away. If you have prostate problems or high blood pressure for which you take medicines called alpha blockers or other anti-hypertensives, your doctor may start you on a lower dose of STENDRA.

Drinking too much alcohol when taking STENDRA may lead to headache, dizziness, and lower blood pressure.

STENDRA in combination with other treatments for ED is not recommended.

STENDRA does not protect against sexually transmitted diseases, including HIV.

The most common side effects of STENDRA are headache, flushing, runny nose and congestion.
