SAN DIEGO, July 17, 2019 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ:DARE), a leader in women’s health innovation, today announced that it has received notification from the American Association of Pharmaceutical Scientists (AAPS) of a Best Abstract Award for the abstract titled, Vaginal Tamoxifen for Treatment of Vulvovaginal Atrophy: Pharmacokinetics and Safety in a Rabbit Model. The abstract was among the top 10% of abstracts highly ranked by AAPS Abstract Screeners.
The abstract presented topline findings from a pharmacokinetic and local tolerability study of vaginal tamoxifen in female rabbits. Daré’s product candidate, DARE-VVA1, incorporates tamoxifen in a proprietary formulation designed for vaginal delivery.
Daré is investigating the use of tamoxifen, a commonly prescribed treatment for breast cancer, as a new way of addressing vulvar and vaginal atrophy (VVA) for women unable or unwilling to use hormone-based therapies to treat their condition. VVA is an inflammation of the vaginal epithelium due to the reduction in levels of circulating estrogen. Historically, estrogen creams, rings, and tablet supplements have been prescribed for the treatment of VVA. These products, however, can be contraindicated for women undergoing treatment for hormone receptor-positive breast cancer.1
“This work is fundamental to the further development of a vaginally delivered tamoxifen for the treatment of symptoms associated with VVA in hormone receptor-positive breast cancer patients,” said Dr. David Friend, Chief Scientific Officer of Daré Bioscience. “These results are highly encouraging and support the further development of vaginally delivered tamoxifen for the treatment of VVA.”
Many breast cancer survivors experience menopausal symptoms, including VVA, as a direct consequence of their anti-cancer treatment with aromatase inhibitors. Breast cancer patients treated with aromatase inhibitors refer to VVA as one of the most unpleasant side effects of treatment.2
“If successful, vaginally delivered tamoxifen will address a critical unmet need for women diagnosed with hormone receptor-positive breast cancer experiencing the effects of VVA as a result of their anti-cancer therapy,” said Sabrina Martucci Johnson, President & CEO of Daré Bioscience. “Consistent with our portfolio of first-in-category opportunities, we believe this novel application of tamoxifen has the potential to be the first therapy that will specifically address VVA in the hormone receptor-positive breast cancer market segment.”
Tamoxifen is systemically metabolized to active metabolite 4-hydroxy-N-desmethyl-tamoxifen, otherwise known as endoxifen.3 In breast tissue, tamoxifen acts as an estrogen antagonist. In other tissue, including vaginal tissue, tamoxifen has been reported to exert an estrogen-like response on vaginal cytology by a mechanism yet to be understood and not expected based upon its anti-estrogen activity.
