VIVUS and Auxilium Announce FDA Acceptance of Supplemental Filing Seeking an Update of Prescribing Information for STENDRA (Avanafil)

MOUNTAIN VIEW, Calif. and CHESTERBROOK, Pa., Jan. 21, 2014 (GLOBE NEWSWIRE) -- VIVUS, Inc. (Nasdaq:VVUS) and Auxilium Pharmaceuticals, Inc. (Nasdaq:AUXL) today announced that the U.S. Food and Drug Administration (FDA) has accepted a supplemental application that proposes to revise the STENDRA (avanafil) prescribing information with efficacy and safety information from Study TA-501, entitled "A Randomized, Double-Blind, Placebo-Controlled Evaluation of Avanafil for On-Demand Treatment of Men with Erectile Dysfunction." The PDUFA date for the supplemental filing is September 20, 2014.

VIVUS had previously announced positive results from this multicenter, placebo-controlled study designed to assess the efficacy of two dosage strengths of STENDRA approximately 15 minutes after dosing.

In the 440-patient study conducted at 30 sites in the U.S., STENDRA patients achieved statistically significant improvement versus placebo in the mean proportion of attempts that resulted in erections sufficient for successful intercourse as early as 10 minutes for the 200 mg dose and 12 minutes for the 100 mg dose following administration. The currently approved prescribing information recommends administration approximately 30 minutes before sexual activity.

About Avanafil

STENDRA (avanafil) is approved by the FDA in the U.S. for the treatment of erectile dysfunction. STENDRA is rapidly absorbed and should be taken 30 minutes before sexual activity on an as-needed basis. STENDRA should not be taken more than once per day and may be taken without regard to food and with modest alcohol consumption. Auxilium Pharmaceuticals, Inc. has exclusive marketing rights to STENDRA in the U.S. and Canada and is in the early stages of commercializing STENDRA in the U.S.

STENDRA is currently available through retail and mail order pharmacies. Auxilium offers programs that will help patients with out-of-pocket costs.

SPEDRA, the trade name for avanafil in the European Union (EU), is approved by the European Medicines Agency (EMA) for the treatment of erectile dysfunction in the EU. VIVUS has granted an exclusive license to the Menarini Group through its subsidiary Berlin-Chemie AG to commercialize and promote SPEDRA for the treatment of erectile dysfunction in over 40 European countries plus Australia and New Zealand.

Avanafil is licensed from Mitsubishi Tanabe Pharma Corporation (MTPC). VIVUS owns worldwide development and commercial rights to avanafil for the treatment of sexual dysfunction, with the exception of certain Asian-Pacific Rim countries. VIVUS is in discussions with other parties for the commercialization rights to its remaining territories.

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.
