About this study

Official title: Characterizing Oxytocin Response to Oral Estrogen Administration in Adults With Arginine Vasopressin Deficiency

This is an open-label, pilot study, to characterize oxytocin response to a single dose of oral Estrogen-progestin in patients with arginine-vasopressin deficiency compared to healthy controls. The association between oxytocin levels and measures of psychopathology (i.e., anxiety and depression) and quality of life across groups will be examined. We hypothesize that:

  1. Salivary and blood oxytocin response to Estrogen-progestin will be lower in arginine-vasopressin deficiency compared to healthy control.
  2. Lower salivary and blood oxytocin levels will be associated with more severe symptoms of anxiety, depression, and social emotional difficulties as well as lower quality of life.
Being tested
Norethindrone Acetate-Ethinyl Estradiol
Medical subject headings
Diabetes Insipidus, Neurogenic

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Norethindrone Acetate-Ethinyl EstradiolDrug

    Also called Estrogen-progestin

    Estrogen-progestin will be given to participants in both cohorts, arginine-vasopressin deficiency cohort and healthy control cohort.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in peripheral oxytocin concentration from 0 to 24 hours

    Change in peripheral oxytocin concentration from 0 to 24 hours

    Measured: Time points: time 0 min (baseline) and 24 hours

Secondary outcomes (1)
  1. Area under the curve of salivary oxytocin from baseline to 48 hours following Estrogen-progestin administration in patients with arginine-vasopressin deficiency compared to healthy controls

    Difference from baseline to oxytocin peak (blood and saliva) between patients with arginine-vasopressin deficiency compared to healthy controls.

    Correlation between oxytocin area under the curve and psychopathology and quality of life measures across groups.

    Measured: From time 0 min (baseline) to 48 hours

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Norethindrone Acetate-Ethinyl Estradiol in people with Arginine Vasopressin Deficiency and Oxytocin Deficiency, run by Elizabeth Austen Lawson at 1 site in United States.

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 3 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 13 May 2026. 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 States. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 peripheral oxytocin concentration from 0 to 24 hours (time frame: Time points: time 0 min (baseline) and 24 hours). 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 13 May 2026.
