About this study
Official title: A First in Human Study Consisting of a Two-Part, Double-Blind, Placebo-Controlled, Escalating Single and Multiple Dose Study of VA111913 TS in Adult Non-Pregnant Women Volunteers With a Single Dose, Open, Fed vs. Fasting Crossover Phase
This is a first-in-human study of VA111913 TS, a new chemical entity being developed for the treatment of dysmenorrhea. This study is designed to investigate determine the safety, tolerability and pharmacokinetics of VA111913 TS after single and multiple doses in healthy non-pregnant female volunteers of child bearing age.
Read the detailed description
VA111913 TS is a selective V1a-receptor antagonist. The hypothesised mechanism of action of a V1a receptor antagonist in dysmenorrhea has been described in literature. Contractions of the uterine muscle are required for normal menstruation. Women with dysmenorrhea have increased uterine myometrial tone and contractions and decreased blood flow to the uterus. These abnormalities have been shown to lead to the pain experienced in dysmenorrhea. Thus, if a drug is able to reduce the hyperreactivity of the uterus to physiological levels then the pain experienced in dysmenorrhea may be controlled. In humans, vasopressin, via the V1a receptor, is able to potently induce contractions in both uterine smooth muscle and uterine blood vessels. Thus, a V1a receptor antagonist will potentially inhibit these contractions and in turn reduce the pain experienced in dysmenorrhea.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study of Dysmenorrhea, run by Vantia Ltd at 1 site in United Kingdom.
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 2 inclusion and 3 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 25 Jun 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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.
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 25 Jun 2009; AzTrials last refreshed its copy on 26 Oct 2026.
