About

This study is designed to determine the safety and feasibility of using Cerebrolysin in treating primary intracerebral hemorrhage (ICH).

This is a multicenter, prospective, randomized, open-label, blinded end-point, phase IV parallel group study done in specialized stroke treatment centers in Poland. The study objective is to evaluate if a 14-day cerebrolysin treatment initiated within 6 hours of onset of primary lobar hemorrhage in addition to the standard of care that includes early intensive rehabilitation is safe and feasible, affects hematoma growth and improves the outcome.

This study is designed to assess the early effect of using Cerebrolysin in patients after ICH, therefore 3 months of follow-up has been chosen. Patients will receive 50 ml of Cerebrolysin once daily until day 14. Subjects will be evaluated on Day 1 (baseline), Day 2, Day 7, Day 30 and Day 90.

Enrollment to the study is expected to reach 30 subjects in 12 months. The study should be completed within 15 months (the end of study).

The primary outcome measure will be change from baseline in functional independence (mRS 0-2) at Day 90 following stroke onset. The safety outcome will be the number of serious adverse events until Day 30.

Enrollment: 30 estimated patients

Sex: All

Ages: 18 to 80 years old

Inclusion criteria

• Age 18-80 years
• NIHSS ≥8 at randomization

• Ability to provide informed consent
• No history of prior stroke

Exclusion criteria

• Hemorrhage caused by head trauma

• Bilateral fixed dilated pupils
• Extensor motor posturing
• Intraventricular extension of the hemorrhage is visually estimated to involve >50% of either of the lateral ventricles

• End-stage liver disease
• Epilepsy with grand mal seizures
• History of drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements
• Positive urine or serum pregnancy test in female subjects without documented history of surgical sterilization or post-menopausal
• Known life-expectancy of less than 6 months
• No reasonable expectation of recovery, Do-Not-Resuscitate (DNR), or comfort measures only prior to randomization
• Participation in a concurrent interventional medical investigation or clinical trial
• Inability or unwillingness of subject or legal guardian/representative to give written informed consent
• Any condition that would represent a contraindication for cerebrolysin administration
