This is a safety, tolerability, efficacy and pharmacokinetic study of NicaPlant® in subarachnoid haemorrhage patients involving two treatment groups. Both treatment groups will receive standard of care and patients randomised to the investigational group will receive in addition NicaPlant® .~NicaPlant® is a nicardipine modified-release formulation. It is presented in the form of a rod-shaped implant with a 4 mg nicardipine load. Following aneurysm clip ligation, 10 NicaPlant® implants will be placed into the basal cisterns in direct contact with the exposed cerebral blood vessel walls.
This study of NicaPlant® is conducted in patients who have a subarachnoid haemorrhage. Patients will be randomized in two treatment groups. Both groups will receive the standard of care and the investigational group will receive in addition NicaPlant®. NicaPlant® is tested to reduce the long-term complications of aneurysmal subarachnoid haemorrhage (aSAH).
