Intracerebral hemorrhage (ICH)-breakage of a blood vessel with bleeding in the brain-is a devastating form of stroke with a 40-50 percent fatality rate and no proven treatment. Because the majority of deaths from ICH occur within several days of the stroke, interventions for improving outcomes must occur early in the treatment course. Among the potentially modifiable determinants of ICH outcome, hematoma growth is a particularly attractive target for intervention and a major focus of this trial.~The purpose of this study is to determine if an imaging test called computed tomography angiography (CTA) can predict which individuals with ICH will experience significant growth in the size of the hemorrhage. Growth of the hemorrhage can cause additional injury and may worsen the outcome. For individuals who are at high risk for hemorrhage growth based on CTA results (i.e., a positive CTA spot sign, evidence of contrast leakage within the hemorrhage), the study will compare the effects of a drug called recombinant activated factor VII (NovoSeven®) or rFVIIa with a placebo to determine which is better for reducing ICH growth.~The primary goals of this trial are (1) to determine the sensitivity and specificity of the CTA spot sign for predicting hematoma growth; (2) to determine the feasibility of using CTA to identify individuals with ICH who are at high risk of hematoma growth and to select study participants for randomization to treatment with rFVIIa or placebo; and (3) to determine the rate of hematoma growth among spot-positive individuals at 24 hours-comparing individuals treated with rFVIIa to those treated with placebo.~Approximately 184 persons with ICH will be enrolled in one of two study groups at 12 clinical sites across the United States and Canada. Participants with ICH who are determined by CTA to be at high risk for hemorrhage growth (CTA spot sign positive) will be randomized to receive either the active study medication, rFVIIa, at 80 mcg/kg, or to receive a placebo (an inactive substance). Participants with ICH who are determined by CTA not to be at high risk for hemorrhage growth (determined to be CTA spot sign negative) will be enrolled into a prospective observational group.~Duration of the study for participants is approximately 3 months.
