A Randomized, Double-Blind, Placebo-Controlled Trial of Simvastatin on Subarachnoid Hemorrhage-Induced Vasospasm

Completed

Phase 1/2 Results

Results

Mortality was 3/20 in the placebo and 0/19 in the simvastatin group. Study drug was withdrawn in 1 subject in each treatment group for reversible liver enzyme or creatine phosphokinase elevation. Angiographically-confirmed vasospasm occurred in 8/20 placebo and 5/19 simvastatin-treated subjects. Vasospasm-related ischemic infarcts developed in 5/20 placebo and 2/19 simvastatin-treated subjects. Simvastatin for the prevention of delayed cerebral ischemia is safe and feasible after SAH. A larger study is needed to test its efficacy.
