Dose-relationship of Vaginally Administrated Oxytocin in Postmenopausal Women (OXYPEP002)

November 10, 2020 updated by: PepTonic Medical AB

A Double-blind, Placebo Controlled Single Centre Trial to Evaluate the Dose-relationship of the Effects of Vaginally Administered Oxytocin on the Vaginal Mucosal Membrane in Postmenopausal Women With Vaginal Atrophy

Up to 50% of all postmenopausal women, experience vaginal drynes, i.e. vaginal atrophy is a consequence due to the lack of estrogen. In addition, vaginal atrophy is associated with an increased pH, which creates an environment more susceptible to infections . The mucosal epithelium shows signs of severe senile atrophy and cytological examination demonstrate increased number of the basal and parabasal cells and reduced number of superficial cells . Unlike some other menopausal symptoms (for instance hot flushes), vaginal symptoms generally persist or worsen with aging.Oxytocin is a peptide hormone and it is released systemically via the posterior pituitary. The most well known effects of oxytocin are its roles in female reproduction such as facilitation of birth and breast feeding. Oxytocin has also shown to exert positive effects on the proliferation of human vaginal mucosal cells from postmenopausal women, an effect which could be attributed either to the direct stimulation of new cell formation or to an increased production of other growth factors. The primary objective is to investigate the dose relationsship of topical administrated Vagitocin on the vaginal mucosal membrane, measured in the change (%)of superficial cells up to 7 weeks after baseline.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female
