Duchesnay Inc. is seeking Health Canada's approval for ospemifene for the treatment of moderate to severe dyspareunia and vaginal dryness, symptoms of vulvar and vaginal atrophy (VVA), a component of genitourinary syndrome of menopause (GSM)

BLAINVILLE, Quebec, June 10, 2019 - Duchesnay Inc. has filed a New Drug Submission (NDS) with Health Canada for a once-daily oral ospemifene tablet, a non-hormonal SERM (selective estrogen receptor modulator) for the treatment of moderate to severe dyspareunia and vaginal dryness, symptoms of vulvar and vaginal atrophy (VVA) due to menopause, a component of genitourinary syndrome of menopause (GSM).

Dyspareunia and vaginal dryness are among the most common bothersome symptoms of VVA due to menopause. Before menopause, estrogen helps maintain the thickness, elasticity and lubrication of vaginal tissues. However, as women age, estrogen levels decrease, leading to significant structural changes in these tissues, resulting in dryness, itching and burning that cause painful sexual intercourse.

"In keeping with Duchesnay's commitment to women's health, we are pleased to be working with Health Canada on this new drug submission to ensure that Osphena® (ospemifene) will be available in Canada," said Michael Gallo, Vice-President of Regulatory and Medical Affairs at Duchesnay Inc.

Duchesnay acquired the exclusive marketing and distribution rights for Osphena® in the United States and Canada from Shionogi Inc., a leading Japanese pharmaceutical company, in 2017, and has since marketed Osphena® in the United States. In keeping with its commitment to women's health at all stages of their lives, Duchesnay looks forward to launching Osphena® in the Canadian market for the well-being of postmenopausal women.

The product’s safety and efficacy are still under investigation and marketing authorization has not yet been granted.
