Yksityiskohtainen kuvaus

GSK249320 is a humanised monoclonal antibody (mAb) that binds with high specificity to myelin-associated glycoprotein (MAG) and antagonises or neutralises MAG-mediated inhibition and has been shown to improve functional recovery after stroke in pre-clinical models, possibly by promoting neuroregeneration and plasticity. The present study is the first in patients with stroke. The main aim of this study is to select tolerated doses of GSK249320 that can be used in future trials to evaluate its efficacy in improving clinical function in patients recovering from stroke. This clinical trial is designed as a placebo-controlled, single-blind, multicenter study to investigate the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of escalating repeat IV doses of GSK249320. Three sequential dose escalation cohorts (1, 5 and 15 mg/kg) are planned, with 8 patients on placebo and 8 on active in cohort 1 and 4 patients on placebo and 8 on active in cohorts 2 and 3. Each patient will receive 2 repeat IV doses 9 ± 1 days apart and assessments will extend to at least 16 weeks.

Mean Change in Mean Gait Velocity
Aikaikkuna: Baseline (Day 5), Day 30, 60, 90, 112
Gait velocity is an objective, quantitative, reliable, valid and sensitive measure of lower extremity motor recovery in the stroke population. Changes in gait velocity correlates with physical functioning and quality of life. Gait velocity was assessed over a level, indoor 10 meter distance. The time (in seconds) it takes the participant to travel the 10 meter distance was recorded. Participants was asked to walk at their usual or normal pace and may use their normal assistive devices. Baseline assessments were recorded at Day 5 of the study. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline was set to missing as well.
Baseline (Day 5), Day 30, 60, 90, 112
Mean Change in Berg Balance Scale (BBS) Total Score
Aikaikkuna: Baseline (Day 5), Day 30, 60, 90 and 112
BBS is a performance based measure of balance. It is reliable, valid and responsive to change in the stroke population. BBS is a staff-assessed measure that requires the participant to perform 14 activities that evaluate ability to maintain balance. The BBS typically takes 10-15minute to complete. Participants were not allowed to use assistive devices while performing the activities. Each activity was evaluated by direct observation of the participant's performance and was scored on a 5-point ordinal scale (0-4) where a score of 0 represents inability to perform the activity and a score of 4 represents independence in the activity. The minimum total score on the BBS was 0 and maximum was 56. Baseline assessments were recorded at Day 5 of the study. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline was set to missing as well.
Baseline (Day 5), Day 30, 60, 90 and 112
Mean Change in Total Fugl-Meyer Motor (FM) Assessment
Aikaikkuna: Baseline (Day 5), Day 30 and 112
The FM assessment is a staff-assessed, disease specific, quantitative measure of impairment that is used to assess recovery of sensorimotor function post stroke. The FM is designed to assess the domains of motor function, balance, sensation and joint function. For this study, only the motor function domain was assessed. The motor domain scale takes approximately 30 minutes to complete and evaluates both the upper and lower extremities by direct observation of the participant's performance of 50 items that measure movement, coordination, and reflex action. Each item was scored from 0-2 for a minimum total score of 0 (hemiplegia) and a maximum total score of 100 (normal motor performance). Baseline assessments were recorded at Day 5 of the study. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline was set to missing as well.
Baseline (Day 5), Day 30 and 112
Mean Change in Total Box and Blocks Transferred on Affected Side
Aikaikkuna: Baseline (Day 1), Day 30, 60, 90 and 112
The Box and Blocks test is an objective, gross manual dexterity test that is reliable and valid in individuals with upper limb impairments. Box and Blocks was a staff-assessed, participant completed test that required the participant to move small wooden blocks from one side of a partitioned box to the other. The score was determined by the number of blocks transferred within a 60 second time period. More number of blocks transferred as compared to Baseline indicated improvement. Both the impaired and normal limbs were tested, starting with the normal limb. The number of blocks transferred were recorded. Baseline assessments were recorded at Day 1 of the study. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline was set to missing as well.
Baseline (Day 1), Day 30, 60, 90 and 112
Mean Change in Grip Strength on Affected Side
Aikaikkuna: Baseline (Day 1), Day 30, 60, 90 and 112
Grip strength is an objective measure of arm motor recovery in stroke participants and correlate with functional status and predict recovery. Grip strength was evaluated by a hand grip dynamometer. Three replicate trials was collected for both the impaired and normal hand, starting with the normal hand. Each trial was separated by a resting period of approximately 15-30 seconds. Participants was instructed to squeeze as hard as possible while using a standardized position of grip and the resulting dynamometer reading (in kg) was recorded. The grip strength measures was conducted within approximately 5 minutes. Baseline assessments were recorded at Day 1 of the study. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline was set to missing as well.
Baseline (Day 1), Day 30, 60, 90 and 112
Number of Participants With Modified Rankin Scale (mRS)
Aikaikkuna: Day 30 and 90
The mRS was a 6 point scale that measured participant handicap by evaluating limitations in activity and changes in lifestyle. The mRS was staff-assessed and scored from 0=no symptoms at all, 1=no significant disability, 2=slight disability, 3=moderate disability, 4=moderate severe disability, 5=severe disability (severe disability, bedridden, incontinent and requiring constant nursing care and attention). The structured interview was used to administer the mRS. The mRS took approximately 15 minutes to complete when using the structured interview. Number of participants with mRS were reported as per the category of the score.
Day 30 and 90
Change From Baseline of National Institutes of Health Stroke Scale (NIHSS)
Aikaikkuna: Baseline (Day 1), Day 10, 30 and 90
The NIHSS is a staff-assessed, 15 item, standardized, disease-specific, deficit scale which measures neurological impairment and is used to quantify participant status by measuring the severity of the stroke. The total NIHSS score ranged from 0 (No impairment) to 42 (severe impairment). Approximately 15 minutes were needed to complete the NIHSS. The NIHSS will be collected as part of the eligibility requirements to exclude participants who have a deficit that is either too mild or too severe. Only NIHSS certified study personnel recorded the NIHSS. Baseline assessments were recorded at Day 1 of the study. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline was set to missing as well.
Baseline (Day 1), Day 10, 30 and 90
Mean Barthel Total Score
Aikaikkuna: Day 30 and 90
The Barthel was a staff-assessed, 10 item activities of daily living index that evaluated feeding, grooming, dressing, excretion (bowels, bladder and toilet skills), bathing, and mobility (transfers, walking, stairs). The total Barthel score ranged from either 0-20 or 0-100 depending on which scoring algorithm was used where 0= unable or dependent and 20 or 100= independent to perform daily activities. For this study, the 100 point scoring algorithm was used. The Barthel takes approximately 5-10 minutes to complete with the participant.
Day 30 and 90
Mean Total Montreal Cognitive Assessment (MoCA) Score
Aikaikkuna: Day 5 and 90
MoCA was an examiner-administered, screening instrument with good validity, reliability, sensitivity and specificity for mild cognitive dysfunction. The MoCA had been studied in stroke participants and was recommended as a tool to monitor and measure cognitive changes post stroke as part of the 2006 National Institute of Neurological Disorders and Stroke - Canadian Stroke Network Vascular Cognitive Impairment Harmonization Standards. The MoCA assesses eight cognitive domains of visuospatial skills, executive function, language, attention, concentration, working memory, memory, and orientation. Participants were asked to complete 14 activities which the examiner scored according to the standardized scoring instructions. While there was no set time limit imposed on a participant. The total MoCA score ranges from 0-30, where 0= worsening and 30 reflects normal cognitive function.
Day 5 and 90
Mean Geriatric Depression Scale (GDS)
Aikaikkuna: Day 5 and 90
The short form GDS is a measure of depression developed specifically for use in elderly population and is sensitive and valid in the stroke population. The GDS was a participant-completed, 15 item questionnaire where each question referenced how the participant felt over the past week. Each question was answered with either a 'yes' or 'no' response. Of the 15 questions, 10 of them indicate depression when answered 'yes' (questions 2-4, 6, 8-10, 12, 14-15) and 5 indicate depression when answered 'no' (questions 1, 5, 7, 11, 13). Each question received a score of 1 point when the response was indicative of depression. Total score ranged from 0 to 15. the total score ranged from 0-15, where 0 implies no symptoms and higher score implies more severity of symptoms.
Day 5 and 90
Mean Change in Transcranial Magnetic Stimulations (TMS) Evaluated by Peak to Peak MEP by % Stimulation Level
Aikaikkuna: Baseline (Day 1), Day 30 and 112
TMS is an electrophysiological technique that was used to measure neurologic changes associated with recovery from stroke via alterations in the excitability of the motor system. Motor threshold measures reflect global excitability of the corticospinal pathway, including large pyramidal cells, excitatory/inhibitory interneurons, and spinal motorneurons. Motor threshold was recorded as the lowest stimulus intensity (in percent) eliciting motor evoked potentials (MEPs). Baseline assessments were recorded at Day 1 of the study. The change from Baseline was calculated by subtracting the Baseline values from the individual post -randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline was set to missing as well.
Baseline (Day 1), Day 30 and 112
Serum Levels of the S100β Protein
Aikaikkuna: Day 1 (Pre-dose, Post dose 1, 6, 24 hour), Day 5
The serum sample for S100β collected on Day 1 (predose, 1, 6, 12 and 24 hour) and Day 5 and was analyzed for levels. Serum levels of S100β protein were recorded as log transformed values therefore the negative values are reported.
