Inclusion criteria

  • {"criterion_text":"- Male or female patients aged 18-80 years (both inclusive)\n- Moderate or severe SAH diagnosed with CT and caused (or suspected to be caused) by a ruptured saccular aneurysm with symptoms less than 8 hours\n- Intracerebroventricular access obtained within 8 h from start of symptoms\n- A WFNS score 1-5, assessed at any time after SAH diagnosis, but before first dose of IMP\n- Informed consent obtained from a trial guardian prior to initiation of any trial-related procedures."}

Exclusion criteria

  • {"criterion_text":"- The SAH due to other causes (e.g., trauma, rupture of fusiform or mycotic aneurysms)\n- Intraventricular or intracerebral blood, in the absence of subarachnoid blood\n- Expected survival < 48 hours\n- Any severe or unstable chronic or acute concomitant condition, which, in the opinion of the PI/delegate, would affect the assessment of the safety of the IMP\n- Any known or CT evidence of previous major cerebral damage or preexisting cerebrovascular disorders, which in the opinion of the PI/delegate may affect the accurate diagnosis and evaluation of SAH\n- Participation in any other clinical trial with an experimental drug within the last 12 weeks\n- Known allergy to the IMP or its constituents\n- Female patients who are pregnant or breastfeeding. Women of childbearing potential must have a negative plasma or urine pregnancy test at screening"}
