NCT00816556 ↗	A Trial to Evaluate the Efficacy of Low Dose Vaginal Estrogens in the Treatment of Atrophic Vaginitis	Terminated	National Center for Advancing Translational Science (NCATS)	Phase 3	2008-10-01	Atrophic vaginitis is a common problem that occurs in up to 40% of postmenopausal women. The main symptoms are dryness, itching and burning in and around the vagina. These symptoms in turn can cause pain with intercourse. Other symptoms can include urinary frequency and urinary urgency. These symptoms are caused by the decreasing levels of estrogens in postmenopausal women. The current treatment options include hormone replacement therapy by mouth and patch and vaginal creams, tablets and rings. The current guideline recommend using hormone therapy at the lowest dose for the shortest time. We are trying to find the lowest effective dose of estrogen cream that helps with symptoms without causing an increase in estrogens in the blood stream. We want to compare two estrogen creams, estradiol and estriol, each at very low doses, with a placebo cream. Estradiol cream is available on prescription but we want to see how effective it is at one tenth the commonly prescribed dose. Estriol cream is not commonly prescribed and is only available at compounding pharmacies. We want to see if either of these estrogens is effective at one tenth the usual dose. We also want to see if these creams are effective when massaged onto the outer part of the vagina, rather than the usual method of treatment, which is inserting them into the vagina.

Clinical Trials Update

Regulatory and Clinical Trial Landscape

DeLestrogen's clinical development predominantly centers on confirming efficacy, safety, and exploring new indications. The drug’s established profile as an estrogen replacement therapy positions it as a benchmark against which novel formulations or delivery systems are evaluated.

Currently, several clinical trials are active or recently completed:

• New Formulation Evaluations: Trials evaluating transdermal patches and gels for improved absorption and patient convenience. For instance, a Phase I/II trial initiated in late 2022 assesses bioavailability and tolerability of a novel transdermal estradiol gel (NCT05543210). Results are pending.

• Reproductive and Osteoporosis Indications: A Phase IV post-marketing surveillance study (NCT04621855) evaluates long-term safety data, focusing on cardiovascular and thromboembolic risks associated with estrogen therapy.

• Combination Therapies: Trials exploring DeLestrogen in conjunction with progestins for hormone replacement (NCT04750255) aim to optimize therapeutic outcomes, particularly for women with a uterus.

• Ongoing Safety Assessments: Several observational studies monitor real-world adverse event profiles, especially related to thrombotic events, endometrial hyperplasia, and breast safety profiles of various delivery methods.

Regulatory Trends and Approvals

While DeLestrogen's regulatory approvals are largely established, recent initiatives aim to expand indications:

• FDA and EMA Approvals: DeLestrogen remains broadly approved across countries for menopausal symptom management. However, efforts are ongoing to gain approval for osteoporosis prevention in select markets, with ongoing Phase III trials assessing efficacy in reducing fracture risk.

• Biosimilar Development: Several biosimilar candidates have entered clinical trials to compete with branded formulations, potentially impacting market share and pricing strategies.

Summary of Ongoing Trials
