Postmenopausal Canadian women with vaginal dryness


BLAINVILLE, Quebec, Feb. 14, 2022 (GLOBE NEWSWIRE) — Duchesnay Inc., a women’s health pharmaceutical company and part of the Duchesnay Pharmaceutical Group based in Blainville, Quebec, is proud to announce the first of its new company launched treatment Owner and management team to help postmenopausal women across Canada suffering from vaginal dryness and painful intercourse.

Osphena® (ospemifene tablets), a selective estrogen receptor modulator (SERM) now available across Canada, has been approved by Health Canada as a once-daily prescription treatment for this indication.

Osphena® has been shown in phase II and III clinical trials to treat moderate to severe dyspareunia (painful sexual intercourse) and/or vaginal dryness in postmenopausal women presenting with symptoms of vulvar and vaginal atrophy (VVA), a component of the menopausal urogenital syndrome (GSM).

“In our culture, the issue of painful sex is often ignored, but it’s a sad reality for many women, especially during the menopause,” said Dr. Michelle Jacobson, obstetrician-gynecologist and menopause specialist at Women’s College and Mount Sinai Hospital in Toronto. “Having a once-a-day treatment option to help these women and their partners is exciting news for them and their doctors. The more we can individualize the therapy, the better we can influence quality of life and functionality.”

“Consistent with Duchesnay’s longstanding commitment to women’s health, we strive to continue to consolidate treatment options for physicians and are pleased to bring this important new therapy to Canadian women who are experiencing these debilitating symptoms due to VVA,” said Dany Hallé, Vice-President, Commercial Affairs, Duchesnay Inc. “Osphena® has been available from Duchesnay USA for several years, where it has been both commercially successful and well received.”

First product launch by new ownership team
Osphena® is the first new drug from Duchesnay since the company changed ownership last year. “As we execute the first part of the company’s strategic plan, we hope to bring two more innovative treatments to Canadian patients in the coming months. This paves the way for Duchesnay’s bright future while shifting paradigms around women’s health, all made possible with the support of our partners at Business Development Bank of Canada (BDC) and Bank of Montreal (BMO), who I want to thank,” said Éric Gervais, President.

Frequent menopausal symptoms
Dyspareunia and vaginal dryness are among the most common and bothersome symptoms of VVA due to menopause, affecting approximately half of postmenopausal women. Before menopause, estrogen helps maintain the thickness, elasticity, and lubrication of vaginal tissues. However, as we age, estrogen levels drop, causing changes in these tissues that can lead to dryness, itching, burning, and pain during intercourse.1

According to a US survey of 1,858 postmenopausal women, about half of the participants rated the severity of vaginal dryness and dyspareunia (painful intercourse), the two most common bothersome moderate to severe symptoms of VVA.2 Both conditions are components of menopausal urogenital syndrome (GSM), which is caused by significant changes in vaginal tissues resulting from local estrogen deficiency.3,4

Osphena® is a selective estrogen receptor modulator (SERM) that is thought to work in a similar way to estrogen in the vagina. It does this by increasing the thickness of the vaginal walls and restoring proper acidity in the vagina.3

Duchesnay Inc. acquired the US and Canadian rights to Osphena® from Shionogi Inc. in 2017 after it received US Food and Drug Administration approval in February 2013. Osphena® is included in the guidelines of the American College of Obstetricians and Gynecologists (ACOG)5the North American Menopause Society (NAMS)6 and the Society of Obstetricians and Gynecologists of Canada (SOGC).7

There is a potentially increased risk of endometrial cancer in a woman with a uterus that uses unopposed estrogens.3
