Expansion of recruitment time window in antihypertensive treatment of acute cerebral hemorrhage (ATACH) II trial.
The Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH) II trial is an ongoing multi-center, randomized phase III trial to determine the efficacy of early, intensive, antihypertensive treatment using intravenous (IV) nicardipine initiated within 3 h of onset of intracerebral hemorrhage (ICH). On March 11th, 2012, the National Institutes of Neurological Disorders and Stroke approved recruitment of patients with ICH within 4.5 h of symptom onset. ⋯ Another recent single center study further identified that hematoma expansion, the primary target for systolic blood pressure reduction, appeared to be equally prevalent in subjects who are presenting between 3 and 4.5 h. The expansion has the potential to evaluate the efficacy of the treatment intervention in a larger group of patients with ICH.
