Szczegółowy opis
This study was first registered as NCT00826059 on January 19, 2009 under the name ImpACT-24.
Background:
Recruitment to ImpACT-24 was halted, the protocol was amended and then the study was resumed. Later, it was decided to define the first part (before the halt) as a separate study - ImpACT-24A, and identify the continuation of the study as ImpACT-24B. ImpACT-24B continues to be registered as NCT00826059, and ImpACT-24A is registered in this new record.
Detailed Description:
A multi-center, multinational, randomized, double blind, sham control, adjunctive to Standard of Care, parallel arm study with ongoing DSMB review of accumulated safety data.
Screening:
Treatment should be initiated between 8 and 24 hours from stroke onset. All screened patients will be identified by patient number and will sign the informed consent prior to any study procedure initiation.
Period 1: Day 1-5
Day 1- Eligible subjects will be randomized in a 2:1 (ISS Stimulation: Sham Control) ratio:
Group 1: Implantation and ISS Stimulation during five consecutive days & Standard of Care Group 2: Implantation and Sham Stimulation during five consecutive days & Standard of Care The implantation will be performed by a trained physician. Stimulation/sham stimulation will be delivered Day 2-5 ISS / Sham Stimulation will be repeated during the following four consecutive days by trained personnel within 18-26 hours from preceding stimulation.
Day 5 / Day of Discharge. Following the last ISS /Sham Stimulation, explantation will be performed.
Subjects will continue with Standard of Care as needed and will be released from the hospital upon investigator's judgment.
Period 2: Day of Discharge - 90±7 days During this period both groups (ISS Stimulation and Sham Control) will be treated according to Standard of Care either at the hospital, rehabilitation center or at home.
Scheduled visits will be performed on day 30±7 and day 60 ±7, which will include safety and effectiveness assessments.
Final Visit Day 90±7 days: The final visit will be performed at the study site and will include safety and effectiveness evaluations.
Patients will be contacted by study personnel via telephone on Day 180±7 and on Day 360±7 in order to assess their quality of life status.

Binary NIHSS at Day 90
Ramy czasowe: 90 ±7 days
|
Binary NIHSS (success for score ≤1 or for ≥ 9-point improvement versus baseline) The NIHSS (National Institute of Health Stroke Score) is a 42-point scale that quantifies neurological deficits in 11 categories. Ratings for each item are scored with 3 to 5 grades, with 0 as normal. |

Stroke-related quality of life at 3 months: Stroke Impact Scale-16
Ramy czasowe: 90 ±7 days
|
Stroke-related quality of life at 3 months according to the Stroke Impact Scale-16 (SIS-16) The scale is based on a questionnaire with 16 items. Each answer ranges from 1 (poor) to 5 (good). A final single-item Recovery domain assesses the individual's perception of his/her recovery from stroke, where: 0 = no recovery 100 = full recovery. Domain scores range from 0-100 and are calculated using the following equation: Domain score = [(Mean item score - 1) / (5-1) ] x 100 |
