A Study of Commercial DEFINITY® to Monitor the Effects of the Heart's Pulmonary Artery Pressure

November 6, 2020 updated by: Lantheus Medical Imaging

A Phase IV, Open-Label Safety Evaluation of the Effect of DEFINITY® on Pulmonary Artery Hemodynamics in Patients With Normal and Increased Pulmonary Artery Pressure

The purpose of this clinical research is to learn if DEFINITY® 416 will cause any adverse effects during Right Heart Catheterization. This research was requested by the FDA.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This Phase IV safety study will provide safety data on potential systemic and pulmonary hemodynamic effects caused by the administration of DEFINITY® in patients who are to undergo right heart cardiac catheterization for clinical reasons. Using a right heart catheter for direct measurements of pulmonary artery hemodynamics will allow accurate assessments of potential alterations of the pulmonary vasculature. This will be further investigated by the inclusion of two patient populations, one with a baseline pulmonary artery pressure < 35 mmHg, and one with elevated baseline pulmonary artery pressure. The addition of immune parameter measurements will assess a potential link between systemic and pulmonary alterations and potential immune reactions following DEFINITY® administration.

The inclusion of patients in this study is not based on a required echocardiogram with DEFINITY® administration because patients would be exposed to an unjustifiable risk of invasive right heart catheterization and are unlikely to consent to such a procedure. Therefore, patients undergoing heart catheterization for clinical reasons, or patients who are undergoing pulmonary artery hemodynamic assessments will be enrolled and receive DEFINITY® in this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers
