What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test the safety and effectiveness of the IRRAflow® System, a catheter system for draining fluid from the brain in individuals with intraventricular hemorrhage. It compares this new system to the standard tubes typically used for the same purpose. The trial seeks participants who have had a brain bleed confirmed by a CT or MRI scan and require brain fluid drainage. Treatment must begin within 72 hours of the bleeding event. As an unphased trial, this study offers participants the chance to contribute to innovative research that could enhance future treatment options.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the IRRAflow® Catheter System is safe for intraventricular hemorrhage treatment?

Research shows that the IRRAflow® Active Fluid Exchange System is generally well-tolerated by patients. In earlier studies, patients using the IRRAflow system experienced positive safety outcomes. Specifically, it caused fewer blockages and infections compared to traditional drainage methods.

The FDA has approved the IRRAflow system for the procedure under study, strongly indicating its safety for people. This approval confirms that it has been checked for safety and effectiveness for this specific use. Therefore, participants in this trial can feel reassured knowing that previous research and FDA approval support the system's safety. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the IRRAflow® Catheter System because it offers a novel approach to managing intraventricular hemorrhage. Unlike traditional external ventricular drains, which passively remove fluid, the IRRAflow system actively exchanges fluids. This active fluid exchange could potentially speed up the removal of blood from the brain, reducing pressure and improving recovery time. By enhancing the efficiency of fluid removal, the IRRAflow system aims to improve patient outcomes more effectively than current standard treatments.

What evidence suggests that the IRRAflow® Catheter System is effective for reducing intracranial pressure?

In this trial, participants will be evaluated using either the IRRAflow® Active Fluid Exchange System or traditional external ventricular drains. Research has shown that the IRRAflow® system quickly clears brain bleeding by actively moving fluid, which is faster than traditional gravity-based methods. Studies have found that this system can reduce complications and improve certain health outcomes. By actively controlling fluid flow, it can lead to better patient recovery. The system reliably speeds up fluid removal from the brain, which is crucial for reducing pressure inside the skull. Overall, the FDA-approved IRRAflow system has shown promise in treating conditions like intraventricular hemorrhage, or bleeding in the brain's ventricles. ^{1 2 4 6 7}

Are You a Good Fit for This Trial?

This trial is for adults over 18 with a type of stroke that causes bleeding inside the brain's ventricles and requires fluid drainage. They must be able to start treatment within 72 hours of their stroke. Pregnant or nursing women, or those with fixed and dilated pupils, cannot participate.

Inclusion Criteria

My doctor has confirmed I need active treatment.

I need a procedure to drain fluid from my brain.

You have bleeding inside your brain as shown on a head CT or MRI scan.

Exclusion Criteria

I am not pregnant or nursing.

My pupils are fixed and do not respond to light.

What Are the Treatments Tested in This Trial?

Interventions

• IRRAflow® Active Fluid Exchange System
• Traditional extraventricular drain

Trial Overview

The study compares the IRRAflow® Active Fluid Exchange System, which is FDA approved, to traditional drains in managing intracranial pressure after an intraventricular hemorrhage. Participants will also undergo non-contrast head CT scans as part of the evaluation.

How Is the Trial Designed?

Group I: IRRAflow with Active Fluid Exchange arm Experimental Treatment 2 Interventions

The analysis of the IRRAS catheter will occur prospectively if it is determined the patient meets the enrollment criteria.

Group II: Retrospective analysis of traditional external ventricular drains Active Control 1 Intervention

The retrospective analysis will be performed on the last 60 traditional external ventricular drains.

IRRAflow® Active Fluid Exchange System is already approved in United States for the following indications:

The IRRAflow® system, used for continuous irrigation and drainage of the cerebral ventricles, showed marked improvement in three patients with cerebral ventriculitis, indicating its efficacy in managing this life-threatening condition.

This system may also be beneficial for treating other brain injuries, such as intraventricular hemorrhage and intracranial abscesses, suggesting its versatility in neuro-intensive care settings.
