Identifying Oxytocin Deficiency in Adults With Pituitary Disease

NCT06460948 | Completed Early Phase 1 FDA Drug

• 1 other identifier: 2024P001090
• Study Type: interventional
• Target: 28
• Locations: 1 country
• Sites: 1

Brief Summary

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. 1.Salivary and blood oxytocin response to Estrogen-progestin will be lower in arginine-vasopressin deficiency compared to healthy control.
2. 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.

Conditions

Arginine Vasopressin Deficiency; Oxytocin Deficiency

Outcome Measures

Primary Outcomes (1)

• Change in peripheral oxytocin concentration from 0 to 24 hours

  Change in peripheral oxytocin concentration from 0 to 24 hours

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

Secondary Outcomes (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

  From time 0 min (baseline) to 48 hours
