  Purpose
Astragalus membranaceus (AM) is used to treat stroke for a long time, and a number of studies have shown that AM can reduce cerebral infarction area and has anti-oxidation activity. PG2, a sterile powder of polysaccharides isolated from the root of astragulus (Huang-Chi) for intravenous injection, has been approved as a botanical drug by TFDA. Hemorrhagic stroke will induce secondary peri-blood clot edema and that may increase intracranial pressure to exacerbate clinical symptom. Therefore, the purpose of the present study was to investigate the efficacy of PG2 on hemorrhagic stroke.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: The Pilot Clinical Study of PG2 Injection on Hemorrhagic Stroke

Primary Outcome Measures:
  • Functional Independence Measure (FIM) [ Time Frame: FIM will be evaluated on day 1 (baseline, before study drug treatment), day 7, day 28 and day 84. ]

Secondary Outcome Measures:
  • Other clinical symptoms including Glasgow outcome scale (GOS), modified rankin scale (MRS), and Barthel Index (BI) [ Time Frame: These clinical symptoms will be evaluated on on day 1 (baseline, before study drug treatment), day 7, day 28 and day 84. ]
  • Inflammatory index including C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR), S-100 protein, IL-1, IL-6, and TNF-beta levels. [ Time Frame: These index will be detected on day 1 (baseline, before study drug treatment), day 4 and day 7. ]

Detailed Description:
This will be a double-blind, randomized, placebo-controlled study. An estimated 60 (at least 48 evaluable) first hemorrhagic stroke patients will be randomly divided into the control and treatment groups. Each group will be treated as follows: 1) control group will accept placebo t.i.w treatment for 14 days from second day of admission, in addition to standard ordinary treatment.; 2) treatment group will accept PG2 t.i.w treatment for 14 days from second day of admission, in addition to standard ordinary treatment. Inflammatory index including the levels of C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR), S-100 protein, IL-1, IL-6, and TNF-beta levels will be measured and clinical symptoms including Glasgow outcome scale (GOS), modified rankin scale (MRS), Functional Independence Measure (FIM) and Barthel Index (BI) will be evaluated during this study.
