Randomized Controlled Trial Multicenter Study Clinical TrialEfficacy and safety of the endothelin, receptor antagonist TAK-044 in treating subarachnoid hemorrhage: a report by the Steering Committee on behalf of the UK/Netherlands/Eire TAK-044 Subarachnoid Haemorrhage Study Group.
Delayed cerebral ischemia remains an important cause of death and disability in patients who have suffered subarachnoid hemorrhage (SAH). Endothelin (ET) has a potent contractile effect on cerebral arteries and arterioles and has been implicated in vasospasm. The authors administered ET(A/B) receptor antagonist (TAK-044) to patients suffering from aneurysmal SAH. They then assessed whether this agent reduced the occurrence of delayed cerebral ischemic events and examined its safety profile in this group of patients. ⋯ The TAK-044 was well tolerated by patients who had suffered an SAH, even though hypotension and headache--side effects compatible with the drug's vasodilatory properties--occurred. It would be valuable to proceed to a fully powered phase III trial of an ET receptor antagonist in treating aneurysmal SAH.
