What this trial studies

This randomized, placebo-controlled, double-blind trial investigates the use of intranasal oxytocin (OXT) as a potential treatment for psychological symptoms in patients with central diabetes insipidus (cDI). The study aims to address the residual psychological issues, such as anxiety and impaired social functioning, that persist despite conventional treatment with desmopressin. Participants will receive either OXT or a placebo and may also take part in optional sub-studies involving fMRI and social stress assessments. The goal is to determine if OXT can improve socio-emotional functioning in these patients.

Who should consider this trial

Good fit: Ideal candidates include adults diagnosed with central diabetes insipidus who experience heightened anxiety or difficulties in emotional recognition.

Not a fit: Patients with active substance use disorders, psychotic disorders, or those who have recently participated in other investigational drug trials may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly enhance the quality of life for patients with central diabetes insipidus by alleviating psychological symptoms.

How similar studies have performed: While the approach of using oxytocin for psychological symptoms in cDI is novel, similar studies have shown promise in other conditions related to socio-emotional functioning.
