Effects of Cerebrolysin Combined With Rehabilitation on Motor Recovery in Stroke

Effects of Cerebrolysin Combined With Rehabilitation on Motor Recovery in Patients With Severe Motor Involvement at Subacute Phase of Stroke

This study, E-COMPASSII is a phase IV clinical trial designed as a multicenter, randomized, double-blind, placebo-controlled, parallel-group study. This study will enroll 80 subacute stroke patients with severe motor involvement. Primary objective is to demonstrate the efficacy of porcine brain peptide to improve motor recovery measured by the improvement ratio of Fugl-Meyer assessment ((score of FMA after 3 weeks - score of FMA at baseline) / score of FMA at baseline) in patients with subacute stroke. Secondary objectives are to evaluate the safety profile of cerebrolysin and to test the hypothesis that subacute stroke patients with severe motor involvement randomized to administration of Cerebrolysin combined with rehabilitation for 3 weeks show better outcome on global function (Korean version Modified Barthel Index, K-MBI), severity of stroke (National Institute of Health Stroke Scale, NIHSS), cognitive function (Korean Version of Mini-Mental State Exam, K-MMSE; Korean version Montreal Cognitive Assessment, K-MoCA), upper limb function (Action Research Arm Test, ARAT; Box and block test, B&B) and neuroplasticity measure (resting-state functional MRI(rsfMRI), diffusion tensor image(DTI), and motor evoked potential(MEP)) at 3 months after stroke.

Randomized double-blinded, placebo-controlled multicenter study with two treatment groups

Number of Patients: 80 patients (n = 40 per group) 5 study centers will participate in this study.

Group 1(Cerebrolysin): cerebrolysin 30 ml with 100 ml dilution/day * 21 days with rehabilitation

Group 2(Placebo): saline 100 ml/day * 21 days with rehabilitation

Inclusion Criteria:

3. Pre-existing and active major neurological disease
4. Pre-existing and active (e.g., on chronic medication) major psychiatric disease, such as major depression, schizophrenia, bipolar disease, or dementia
5. A history of significant alcohol or drug abuse in the prior 3 years
6. Advanced liver, kidney, cardiac, or pulmonary disease
7. A terminal medical diagnosis consistent with survival < 1 year
8. Substantial decrease in alertness at the time of randomization, defined as score of 2 on NIH Stroke Scale
9. Pregnancy or lactating; note that a negative pregnancy test will be required if the patient is a female in reproductive years
10. Any condition that would represent a contraindication to Cerebrolysin, including allergy to Cerebrolysin
