Sumitomo Pharma and Pfizer Canada Announce Availability of MYFEMBREE® in Canada

MISSISSAUGA, ON and KIRKLAND, QC, Jan. 31, 2024 /PRNewswire/ -- In partnership with Sumitomo Pharma Canada, Inc., Pfizer Canada ULC is proud to announce that supply of MYFEMBREE® (relugolix 40 mg, estradiol 1 mg and norethindrone acetate tablets 0.5 mg tablets) is now available in Canada by prescription for the management of moderate to severe pain associated with endometriosis in pre-menopausal women, as well as for the management of heavy menstrual bleeding associated with uterine fibroids in pre-menopausal women.1

"For many fibroid and endometriosis patients, symptoms can be debilitating. These conditions progress for years, while women are simultaneously managing jobs and families," said Patricia Lee, Founder of CANFib (Canadian Women with Fibroids). "MYFEMBREE being added to Canada's toolbox means women with endometriosis and uterine fibroids have much-needed access to new treatment options for their symptoms."  

"The introduction of MYFEMBREE represents a significant advance in the care of pre-menopausal patients battling with endometriosis and uterine fibroids," said Dr. Jamie Kroft, Deputy Chief, Obstetrics & Gynaecology - Minimally Invasive Gynaecologic Surgery at Sunnybrook Health Sciences Centre and Associate Professor, at the University of Toronto. "Providing new options for managing these conditions is a positive step forward in supporting patients' well-being and offering renewed optimism in their treatment journey."

As previously announced, Pfizer Canada ULC will lead commercialization efforts of MYFEMBREE for both the uterine fibroid and endometriosis indications in Canada.

About Uterine Fibroids

Uterine fibroids are the most common benign tumors in women of reproductive age.2 Uterine fibroids may be underdiagnosed due to several factors. Roughly 50 to 80% of women may have asymptomatic fibroids, meaning they don't experience noticeable symptoms. Additionally, some women with fibroid-related symptoms, such as heavy menstrual bleeding and pain, might not seek medical attention because they consider these issues to be a normal part of their menstrual cycles. Furthermore, healthcare providers may sometimes dismiss these symptoms as normal, contributing to the underestimation of uterine fibroid prevalence in Canadian women.3,4,5,6

About Endometriosis

Endometriosis is a chronic disease characterized by growth of endometrial-like tissue outside the uterus.7 This growth of endometriotic tissue relies on estrogen, a hormone crucial for regulating the female reproductive system.8 Endometriosis mainly affects women of reproductive age, occurring between their first menstrual period and menopause, when estrogen levels decline.9 In Canada, 7.0% of women aged 18-48 have endometriosis, with an average diagnosis age of 27.9. Most Canadian women with endometriosis experience symptoms before diagnosis with an average delay of 5.4 years in diagnosis.10 Symptoms include menstrual pain, pelvic pain, and pain during sex, with 60% reporting moderate to severe pain.6,9,11 Endometriosis can impact fertility, quality of life, and work productivity.12
