Duchesnay Inc. Receives Approval of Supplemental New Drug Application (sNDA) to Add Moderate to Severe Vaginal Dryness, a Symptom of Vulvar and Vaginal Atrophy (VVA) Due to Menopause, to the Indication of Osphena® (ospemifene)

BLAINVILLE, QC, Jan. 29, 2019 /PRNewswire/ - Duchesnay Inc., a pharmaceutical company specializing in women’s health, announced today that the FDA has approved its supplemental New Drug Application (sNDA) seeking to add moderate to severe vaginal dryness, a symptom of vulvar and vaginal atrophy (VVA), due to menopause, to the indication of Osphena^® (ospemifene).

The sNDA was based on new safety and efficacy data acquired through a confirmatory phase 3 randomized, double blind, placebo-controlled multicenter study evaluating the efficacy and safety of ospemifene in patients with moderate to severe vaginal dryness. Osphena^® is non-hormonal and helps improve specific vaginal tissues by increasing superficial cells, decreasing parabasal cells and reducing vaginal pH.

Prior to this approval, Osphena^® was indicated only for the treatment of moderate to severe dyspareunia (painful intercourse), also a symptom of VVA, due to menopause.

“Many menopausal women are not aware that vaginal dryness is one of the two most common and most bothersome symptoms (MBS) of vulvovaginal atrophy due to menopause. FDA’s approval of this additional indication affirms Osphena^®‘s safety and effectiveness for treating moderate to severe vaginal dryness, broadening its benefits to a larger number of menopausal women,” affirmed Dr. James A. Simon, Clinical Professor of Obstetrics and Gynecology at George Washington University.

Before menopause, estrogen helps maintain the thickness, elasticity and lubrication of vaginal tissues. However, as women age, estrogen levels drop, causing changes in these tissues, which can lead to dryness, itching, burning and painful intercourse.

“With the addition of moderate to severe vaginal dryness to Osphena^®‘s indication, Duchesnay USA can now help postmenopausal women suffering from this symptom of VVA”, explained Dean Hopkins, General Manager of Duchesnay USA. “With this new indication, Osphena^® now provides an oral option for women who prefer a non-hormonal treatment alternative.”

Indication: What is Osphena^®?

Osphena^® is a prescription oral pill that treats: ● moderate to severe painful intercourse, ● moderate to severe vaginal dryness, symptoms of changes in and around your vagina, due to menopause.

Most Important Information you should know about Osphena^®

WARNING: ENDOMETRIAL CANCER AND CARDIOVASCULAR DISORDERS

Osphena^® works like estrogen in the lining of the uterus (endometrium), but can work differently in other parts of the body. Taking estrogen alone or Osphena^® may increase your chance for getting cancer of the lining of the uterus. Vaginal bleeding after menopause may be a warning sign of cancer of the lining of the uterus. Your healthcare provider should check any unusual vaginal bleeding to find out the cause, so tell him or her right away if this happens while you are using Osphena^®.

Osphena^® may increase your chances of having a stroke or blood clots.

You and your healthcare provider should talk regularly about whether you still need treatment with Osphena^®.

Call your healthcare provider right away if you have unusual vaginal bleeding, changes in vision or speech, sudden new severe headaches, and pains in your chest or legs with or without shortness of breath, weakness and fatigue.

Who should not take OSPHENA?

Osphena^® should not be used if you have unusual vaginal bleeding, have or have had certain types of cancers (including cancer of the breast or uterus), have or have had blood clots, had a stroke or heart attack, have severe liver problems, are allergic to Osphena^® or any of its ingredients, or think you may be pregnant. Tell your healthcare provider if you are going to have surgery or will be on bed rest.

Serious but less common side effects can include:

• stroke

Less serious, but common side effects include:

Tell your healthcare provider about all of the medicines and supplements you take, as some medicines may affect how Osphena^® works. Osphena^® may also affect how other medicines work.
