DLBS1033 for Acute Ischemic Stroke Patients (ADDLIST)

Addition of DLBS1033 to Standard Therapy for Acute Ischemic Stroke Patients

This is a prospective, randomized, double-blind, and controlled clinical study to investigate the effects of DLBS1033 in conjunction with standard therapy compared to standard therapy alone in acute ischemic stroke patients. It is hypothesized that the improvement in functional outcomes as measured by NIHSS and BI as well as the improvement in haemostatic parameters as measured by thrombocyte aggregation test (TAT), fibrinogen, and d-dimer in DLBS group will be significantly greater than those in the control group.

Study Overview

• Status: Terminated
• Conditions: Acute Ischemic Stroke; Partial Anterior Circulation Infarct; Lacunar Anterior Circulation Infarct
• Intervention / Treatment: Drug: Placebo; Drug: DLBS1033

Detailed Description

Subjects in this study will be screened consecutively and eligible subjects will be randomized into two groups and receive the investigational drug, DLBS1033 at a dose of 490 mg three times daily or its placebo in addition to standard therapy for 28-days course of therapy. Standard therapy used in this study will consist of: aspirin 80 mg, simvastatin 20 mg, and vitamin B complex.

After hospital admission and diagnosis, patient will be handled as per acute ischemic stroke management in each study site. Right after the patient is confirmed eligible to the study, the treatment(s) will be switched immediately into the study treatments. Clinical and laboratory examinations to evaluate the investigational drug's efficacy will be performed at baseline and 3, 7,14, and 28 days after study medication initiation; while safety examinations will be performed at the same time point, but 3 and 14 days after study medication initiation.
