SASH is a prospective single-arm, single-center, open-label Phase 1 trial of satralizumab 120mg subcutaneous Day 0 and Day 14 in subjects with Hunt Hess grade 1-3, Fisher score 3 aneurysmal subarachnoid hemorrhage and an external ventricular drain or lumbar drain. The trial is designed to demonstrate safety and to detect a signal that satralizumab prevents delayed cerebral ischemia in these patients.
In this study, satralizumab will be administered to see whether satralizumab is safe in patients with a burst brain aneurysm and if it may prevent strokes in patients with a burst brain aneurysm.
