About this study
Official title: A Phase 2b, Double-blind, Randomized, Parallel, Placebo-Controlled Study to Evaluate the 12-week Efficacy of Vagitocin in Postmenopausal Women With Symptoms of Vulvovaginal Atrophy
A randomized, double-blind, placebo controlled Phase 2b study, divided in 2 parts:
- The main part of the study investigates the efficacy and safety of the Investigational Medicinal Product (IMP), intravaginally administered in glass syringes, on postmenopausal women with vulvovaginal atrophy symptoms.
- The exploratory part of the study investigates the efficacy and safety of the IMP, intravaginally administered in a laminate tube, on postmenopausal women with vulvovaginal atrophy symptoms.

A comparison of plasma levels of oxytocin when the IMP is administered by 2 different applicators will be investigated in a sub-group of patients.
In the main part, 160 subjects are enrolled and randomized to 2 different groups; 80 subjects receiving IMP and 80 subjects receiving placebo, in glass syringes. In the exploratory part of the study, 40 patients will be enrolled and randomized to 2 different groups; 30 subjects receiving IMP and 10 patients receiving placebo, in laminate tubes.
The study is conducted at 3 sites in Sweden, and comprises 5 visits: screening visit (Visit 0), randomization visit (Visit 1; Day 0), treatment follow-up visit (Visit 2; Week 4), end of treatment visit (Visit 3; Week 12) and a telephone follow-up visit (Visit 4; Week 14). All patients self-administer the IMP once daily for 12 weeks.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
A randomized, double-blind, placebo controlled Phase 2b study, divided in 2 parts:
- The main part of the study investigates the efficacy and safety of the Investigational Medicinal Product (IMP), intravaginally administered in glass syringes, on postmenopausal women with vulvovaginal atrophy symptoms.
- The exploratory part of the study investigates the efficacy and safety of the IMP, intravaginally administered in a laminate tube, on postmenopausal women with vulvovaginal atrophy symptoms.
A comparison of plasma levels of oxytocin when the IMP is administered by 2 different applicators will be investigated in a sub-group of patients.
In the main part, 160 subjects are enrolled and randomized to 2 different groups; 80 subjects receiving IMP and 80 subjects receiving placebo, in glass syringes. In the exploratory part of the study, 40 patients will be enrolled and randomized to 2 different groups; 30 subjects receiving IMP and 10 patients receiving placebo, in laminate tubes.
The study is conducted at 3 sites in Sweden, and comprises 5 visits: screening visit (Visit 0), randomization visit (Visit 1; Day 0), treatment follow-up visit (Visit 2; Week 4), end of treatment visit (Visit 3; Week 12) and a telephone follow-up visit (Visit 4; Week 14).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Oxytocin 400 IU vaginal gel in people with Vulvovaginal Atrophy, run by PepTonic Medical AB at 3 sites in Sweden.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in severity of the most bothersome VVA symptom. (time frame: Baseline and after 12 weeks of treatment.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Nov 2020; AzTrials last refreshed its copy on 8 Nov 2026.
