Overview

Congenital heart disease occurs in about 1% of live births and can range from (1) naturally curable conditions that require no treatment to (2) conditions that require multiple immediate operations or refractory severe conditions. In the course of a staged surgical intervention, adhesion formation around the heart and large vessels can occur, and dissection of the adhesion site is required at the time of reoperation. There is a concern that dissection may markedly increase the risk of operation such as prolonged surgical time, cardiovascular injury, and increased blood loss, and medical devices to prevent adhesion formation after operation in the field of pediatric cardiovascular operation are strongly desired in medical settings.

The investigational product (BAX602), which has already been manufactured and marketed by Baxter overseas, has been used for open heart surgery as a local hemostatic agent without biological materials in Europe and the US for more than 20 years.

However, since it has not been approved in Japan, this randomized controlled study will be conducted in Japan to demonstrate the effect of BAX602 to prevent and reduce adhesion formation between the surface of the heart/large vessels and surrounding tissues in pediatric patients undergoing planned multistage operation for congenital heart disease.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
