Stockholm, February 10, 2022 – IRRAS, a commercial-stage medical technology company with a comprehensive portfolio of innovative products for neurocritical care, today announced the presentation of the largest dataset to date to document clinical outcomes using its IRRAflow system. The neurosurgery team from the Rockefeller Neuroscience Institute at West Virginia University and WVU Medicine Ruby Memorial Hospital (WVUH), led by Dr. Nicholas Brandmeir, tracked the outcomes from the first 45 patients that they treated with IRRAflow across a variety of intracranial pathologies, and their positive initial results were presented by Dr. Babar Khan at the Neurosurgical Society of the Virginias annual meeting in White Sulphur Springs, West Virginia, on January 27, 2022.
The presented data confirmed the effectiveness of the IRRAflow system’s automated irrigation by showing a 0% occlusion rate during the entire course of treatment. Traditional passive drainage solutions, on the other hand, have catheter occlusion rates up to 47% documented in clinical literature. Additionally, IRRAflow’s mechanism of action was also shown to more effectively remove collected blood after intracranial bleeding. Average treatment time with IRRAflow was 6.8 days, and only 13% of patients required the placement of a shunt after IRRAflow treatment. This percentage of shunt dependence with IRRAflow compares favorably to data from the CLEAR-III where 18% of patients required shunt placement after treatment with a passive ventricular drain.
The WVUH data also highlighted a reduction of vasospasm observed after ruptured cerebral aneurysms compared to higher historic published rates. After intracranial bleeding occurs, the collected blood induces an inflammatory response, which can cause the vessels in the brain to spasm or narrow, limiting blood flow, and putting the patient at risk for a secondary stroke. IRRAflow’s more efficient removal of collected blood resulted in decreased observation of this deadly vasospasm phenomenon.
These positive outcomes that highlight the IRRAflow system’s effectiveness were collected across a wide range of intracranial pathologies, including intraventricular hemorrhage (IVH), ventriculitis, subarachnoid hemorrhage, and subdural hematomas. This data set also serves to further expand the available clinical evidence to document IRRAflow’s ability to safely perform targeted drug delivery with positive results. The WVUH team has delivered medication with IRRAflow to treat 24.4% of their patients to date.
“This data presented by the surgeons from the Rockefeller Neuroscience Institute at West Virginia University further confirms the positive impact that our IRRAflow system is having on a growing number of patients around the world,’ said Will Martin, President and Chief Executive Officer of IRRAS. “Our key corporate objective in 2022 is to document the superiority of our products with robust clinical data, and this early data shows that the use of IRRAflow can result in better patient outcomes, decreased length of hospitalization, and reduced overall cost of care.”
