Sermonix Pharmaceuticals to Present Poster on Physician Perceptions of Menopausal SERMs at San Antonio Breast Cancer Symposium

COLUMBUS, OH--(Marketwired - Nov 28, 2016) - Sermonix Pharmaceuticals LLC, a specialty pharmaceutical company focused on the development and commercialization of female-specific oncology products, today announced that its poster on physician perceptions of estrogen agonist/antagonists in menopausal health has been accepted for presentation at the San Antonio Breast Cancer Symposium (SABC).

The Dec. 6-10 meeting at the Henry B. Gonzalez Convention Center in San Antonio will include the poster "Physician Perceptions of Estrogen Agonist/Antagonists in Menopausal Health: A Survey to Address Osteoporosis, Urogenital Health and Breast Concerns in Menopause and Breast Cancer Survivorship."

The poster's presenting authors are:

  • Shari Goldfarb, M.D., Medical Oncologist, Memorial Sloan Kettering Cancer Center
  • Michael Krychman, M.D., Executive Director of the Southern California Center for Sexual Health and Survivorship Medicine in Newport Beach, California; Medical Director, Sexual Medicine, Hoag Hospital, Newport Beach, California
  • Paul Plourde, M.D., Sermonix Oncology Team Leader
  • David Portman, M.D., Sermonix Chief Executive Officer and Chief Medical Officer

Among the study's findings was that of women suffering from vulvovaginal atrophy (VVA), an average of just 16 percent are reported to be treated with a selective estrogen receptor modulator (SERM).

"Symptoms of vaginal atrophy have a severe detrimental impact on breast cancer survivors' quality of life and should not be ignored," said Dr. Krychman. "Aromatase inhibitors, in particular, have a serious negative health impact for women even after adjuvant endocrine therapy is ceased. There is a need for a non-estrogen treatment, such as oral lasofoxifene, which these women can take for restoring both their bones and their urogenital health while potentially protecting their breasts."

Oral lasofoxifene, Sermonix's lead investigational drug, is a third-generation SERM, also known as an estrogen agonist/antagonist. It's one of the most well-studied drugs in its category, having been evaluated in more than 15,000 women in a comprehensive worldwide phase I-III clinical development program that includes the PEARL, OPAL and other trials, showing a positive impact on VVA in addition to a reduction in the risk of vertebral and non-vertebral fractures.

Sermonix is currently focused on developing lasofoxifene for breast and ovarian cancer treatment, particularly an indication in advanced Estrogen Receptor positive (ER+) endocrine-resistant breast cancer. Seventy percent of the more than 240,000 U.S. women annually diagnosed with breast cancer are ER+ and there are an estimated 3 million living breast cancer survivors.

"There are unmet needs in the breast cancer survivorship population as it relates to osteoporosis and urogenital health," said Dr. Goldfarb. "The good news is that we have treatments for breast cancer. However, many of these therapies create chronic conditions that adversely impact breast cancer survivors' bones and vagina."

Lasofoxifene is being investigated for the treatment of metastatic breast cancer and, if found effective, will have the potential to provide women with an improved alternative to existing endocrine treatments.

"The results of this physician survey highlight the unmet medical needs women have during and after endocrine treatment of their breast cancer," said Dr. Plourde. "Anti-estrogens have been the cornerstone of ER+ breast cancer for decades, yet physicians have underappreciated the impact such therapy has on quality of life. Oral lasofoxifene is a novel investigational agent with a strong anti-estrogen effect on breast. It also has beneficial estrogenic effects on the vagina and bone that helps mitigate bone loss and symptoms related to vaginal atrophy."
