Presentation Summaries:

Vaginal Tamoxifen for Treatment of Vulvovaginal Atrophy: Pharmacokinetics and Safety in a Rabbit Model:

Tamoxifen has been found to be an estrogen agonist in vaginal tissue and thus has pharmacologic effects similar to vaginally applied estrogen (orally, tamoxifen is an estrogen antagonist in breast tissue). This study was designed to evaluate the pharmacokinetics and local tolerability of vaginal tamoxifen in female rabbits. This work is part of an effort to develop a vaginal tamoxifen product capable of treating symptoms of vulvar and vaginal atrophy (VVA) in hormone-receptor positive breast cancer patients.

Vaginally administered tamoxifen showed minimal metabolism which is in contrast to oral administration in other small animal models. The upper dose of 20 mg tamoxifen is the dose administered orally to women diagnosed with breast cancer and thus represents a relatively high exposure per kg in rabbits. The findings of this study support the clinical evaluation of tamoxifen to study the pharmacokinetics and safety in women (initially in post-menopausal women).

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 VVA, 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, however, these products are often contraindicated for women undergoing treatment for hormone receptor-positive breast cancer.1

Evaluation of Different Suppliers of Ethylene Vinyl Acetate Used in Intravaginal Rings:

An investigative study evaluated ethylene vinyl acetate (EVA) copolymer from three different suppliers used to prepare segmented intravaginal rings (IVRs) for the sustained release of estradiol (E2) and progesterone (P). The findings of this study support the conclusion that EVA (28% VA content) from the three different suppliers can be used to prepare IVRs capable of the controlled release of E2 and P. While there were some minor differences between the EVA used (one EVA had a lower melt-flow index than the other two sources) there was remarkable consistency in the results obtained.
