Results of Membrane-activated Chelator Stroke Intervention Randomized Trial of DP-b99 in Acute Ischemic Stroke
Clinical Trials Wednesday, March 6th, 2013STROKEAHA: February 7, 2013
Background and Purpose—DP-b99, a lipophilic moderate-affinity chelator of zinc, was postulated to improve recovery after acute ischemic stroke. We evaluated the safety and therapeutic effects of DP-b99 in patients with acute hemispheric ischemic stroke.
Methods—The Membrane-Activated Chelator Stroke Intervention trial was a randomized, double-blind, placebo-controlled, multicenter, parallel-group trial of intravenous DP-b99 administered for 4 consecutive days (NCT00893867). Acute ischemic stroke patients within 9 hours of onset, but untreated by alteplase, with a baseline National Institutes of Health Stroke Scale score of 10 to 16, and evidence of language dysfunction, visual field defect, and neglect were eligible. The primary efficacy analysis compared distributions of functional status measured by modified Rankin score in the intent-to-treat population of patients with any post-treatment outcome, adjusted for initial severity. Functional and neurological recovery were secondary measures. Home time was an exploratory end point. Read more
