Prehospital Control ArmPLACEBO_COMPARATORIdentical volume saline placebo to prehospital intervention arm provided via intravenous or intraosseous access over approximately 2-5 minutes, initiated prior to trauma bay arrival and infused to completion following arrival if needed
Early In-Hospital Intervention ArmEXPERIMENTAL4-unit vasopressin bolus followed by a vasopressin infusion at 0.04 U/min for 8 hours. Administration of the bolus will be initiated as soon as feasible and within approximately 2 hours of enrollment. The infusion will be initiated within approximately 30 minutes of the bolus.

Frequently asked questions about Vasopressin

What is Vasopressin used for in trauma?

Vasopressin is an investigational small molecule being studied for use in trauma and hemorrhage. It is currently in Phase 2 clinical development, evaluated in the CAVALIER trial for early resuscitation following injury. The drug is being developed by United Therapeutics Corporation.

What does Vasopressin target?

Vasopressin is a small molecule that acts as a vasopressor, helping to constrict blood vessels and raise blood pressure. In the context of trauma and hemorrhage, it is being studied to support resuscitation efforts. The drug is being developed by United Therapeutics Corporation.

Who makes Vasopressin?

Vasopressin is being developed by United Therapeutics Corporation, a biopharmaceutical company traded on the NASDAQ under the ticker UTHR. The company is conducting a Phase 2 clinical trial of Vasopressin for trauma and hemorrhage.

What phase is Vasopressin in?

Vasopressin is in Phase 2 clinical development. It is an investigational drug and has not been approved by the FDA. The ongoing Phase 2 trial, NCT05958342, is currently recruiting participants in the United States.

What clinical trials is Vasopressin in?

Vasopressin is being evaluated in one active Phase 2 clinical trial, NCT05958342, titled 'CAlcium and VAsopressin Following Injury Early Resuscitation (CAVALIER) Trial'. This randomized, double-blind, placebo-controlled study is recruiting 1,050 participants aged 18 years and older with trauma and hemorrhage.

Is Vasopressin the same as other names?

Vasopressin is also known by its chemical name, arginine vasopressin, and is sometimes referred to as antidiuretic hormone (ADH). In the context of this clinical development program, it is being studied under the name Vasopressin by United Therapeutics Corporation.
