Frequently asked questions about Intranasal Oxytocin

What is Intranasal Oxytocin used for?

Intranasal Oxytocin is being studied for the treatment of vasopressin deficiency, a condition also known as arginine-vasopressin deficiency. It is administered as a nasal spray and is currently in Phase 1 clinical development. The drug is being evaluated for its effects in patients with this condition.

Who makes Intranasal Oxytocin?

Intranasal Oxytocin is being developed by Tonix Pharmaceuticals Holding Corp., a biopharmaceutical company traded on the NASDAQ under the ticker symbol TNXP. The company is conducting clinical trials to evaluate the safety and efficacy of this intranasal formulation of oxytocin for vasopressin deficiency.

What phase is Intranasal Oxytocin in?

Intranasal Oxytocin is currently in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. A Phase 1 clinical trial is actively recruiting participants to study its effects in patients with vasopressin deficiency.

What clinical trials is Intranasal Oxytocin in?

Intranasal Oxytocin is being studied in a Phase 1 clinical trial with the identifier NCT04789148, titled 'Effects of Intranasal Oxytocin in Patients With Arginine-vasopressin Deficiency.' The trial is recruiting 40 participants in the United States and is randomized, double-blind, and active-controlled.

Is Intranasal Oxytocin the same as IN-OXT?

Yes, Intranasal Oxytocin is also known as IN-OXT, which stands for intranasal oxytocin. This abbreviation is used in clinical research to refer to the same drug formulation being developed by Tonix Pharmaceuticals for the treatment of vasopressin deficiency.

How does Intranasal Oxytocin work?

Intranasal Oxytocin works by delivering oxytocin, a peptide hormone, through the nasal route. Oxytocin is structurally similar to vasopressin and may compensate for the deficiency of vasopressin in patients with vasopressin deficiency. The intranasal administration allows for direct delivery to the central nervous system.
