Protocol Summary

Protocol No.: OCR19685

Protocol Title.: FILtration of Subarachnoid Hemorrhage Via SpinaL CAtheteR Extension

Principal Investigator: Babi, Marc

Objective: The objective of this study is to further demonstrate safety and characterize effectiveness of the Neurapheresis™ System (extracorporeal system and catheter) to remove red blood cells (RBCs) and lysed blood by-products from hemorrhagic cerebrospinal fluid (CSF) following aneurysmal subarachnoid hemorrhage (aSAH).

Description: The PILLAR-XT study is designed to further confirm safety and characterize efficacy of Neurapheresis therapy. The study works in tandem with the current SOC treatments for SAH and does not detract from the established care pathways, or deny enrolled subjects proven therapies. The PILLAR-XT study utilizes the established skill sets of chosen Investigators who are already trained in the treatment and care of SAH patients and insertion/management of lumbar drains.
