Efficacy and Safety of Actovegin in Post-stroke Cognitive Impairment (PSCI) (ARTEMIDA)
A 12-month, International, Parallel Group, Randomised, Multi-centre, Double-blind, Placebo-controlled Trial to Examine the Effect of Actovegin® Treatment Given First Intravenously and Subsequently Orally Over 6 Months, in Subjects With Post-stroke Cognitive Impairment (PSCI).

Detailed Description
The drug tested in this study is called actovegin. Actovegin was tested to treat people who have post stroke cognitive impairment. This study looked at the improvement of cognitive symptoms in people who take actovegin compared to placebo.
The study enrolled 503 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which remained undisclosed to the patient and study doctor during the study:
- Actovegin-2000 mg intravenous solution; 2- 200 mg tablets 3 times a day
- Placebo intravenous solution; tablets (dummy inactive) - this is a solution or tablet that looks like the study drug but has no active ingredient
All participants received daily intravenous infusions in the hospital (up to a maximum of 20 infusions) followed by 2-200 mg tablets three times a day for the remainder of the 6-month treatment period.
This multi-centre trial was conducted in Belarus, Kazakhstan and Russia. The overall time to participate in this study was 12 months. Participants made multiple visits to the clinic plus a final visit after receiving their last dose of study drug for a follow-up assessment.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Alzheimer's Disease Assessment Scale + Cognitive Subscale Extended Version (ADAS-cog+) at Month 6
Time Frame: Baseline and Month 6
|
The ADAS-cog measures cognitive performance by combining the ratings of 11 items. The cognitive domains mainly addressed by ADAS-cog are: memory (short term), language, ability to orientate (reflects memory), construction/planning of simple designs and performance. The extended version of the ADAS-cog (ADAS-cog+) includes 3 additional items: a 2-number cancellation task to test for attention, a delayed recall task to test for memory consolidation and a maze test for executive performance. Each item is scored and then the item scores are totaled. Total scores range from 0 (best) to 90 (worst). Higher scores indicate greater cognitive impairment. A negative change from Baseline indicates improvement. Analysis of Covariance (ANCOVA) model was used for analyses that included treatment, pooled centre, and their interaction as factors and Baseline ADAS-cog+ score as a covariate. |

|
Change From Baseline in Montreal Cognitive Assessment Scale (MoCA) at End of Infusion Period, Months 3, 6 and 12
Time Frame: Baseline, End of Infusion and Months 3, 6 and 12
|
The MoCA is a rapid screening test to assess mild cognitive impairment. It assesses different cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. Time to administer the MoCA is approximately 10 minutes. The total possible score is 0 to 30 points; a score of 26 or above is considered normal. A positive change from Baseline (BL) indicates improvement. ANCOVA model was used for analyses that included treatment and pooled centres as factors, plus years of education and baseline MoCA score as covariates. |
Baseline, End of Infusion and Months 3, 6 and 12
|
Percentage of ADAS-cog+ Responders at Time Points 3, 6 and 12 Months
Time Frame: Baseline and Months 3, 6 and 12
|
Responder was defined as an improvement of 4 or more from baseline on the ADAS-cog+ scale using observed data.
The proportion of responders was compared between treatments using a chi-square test.
|
Baseline and Months 3, 6 and 12
|
Percentage of Participants With a Diagnosis of Dementia
Time Frame: Month 6
|
Diagnosis of dementia will be evaluated after 6 and 12 months classified according to International Statistical Classification of Diseases and related Health Problems 10th Revision (ICD-10) [Classification of Mental and Behavioural Disorders, Diagnostic Criteria for Research].
The proportion of participants with dementia was compared between treatments using a Fisher's exact test.

Month 6
|
Change From Baseline in National Institutes of Health Stroke Scale (NIHSS) at End of Infusion Period, Months 3, 6 and 12
Time Frame: Baseline and End of Infusion and Months 3, 6 and 12
|
The NIHSS is a tool to objectively quantify the impairment caused by a stroke.
The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 (normal) to 4 (some level of impairment).
The individual scores from each item are summed in order to calculate total possible NIHSS score from 0 (best) to 42 (worst).
A negative change from Baseline indicates improvement.
ANCOVA model was used for analyses that included treatment and pooled centre as factors and Baseline NIHSS score as a covariate.

Baseline and End of Infusion and Months 3, 6 and 12
|
Barthel Index at Months 3 and 6
Time Frame: Months 3 and 6
|
The Barthel Index consists of 10 items that measure a person's daily functioning, specifically the activities of daily living and mobility.
The items include: feeding, transfers (bed to chair and back), grooming, toilet use, bathing, mobility (walking on level surface), going up and down stairs, dressing, continence of bowels and bladder.
Each performance item is rated, with a given number of points assigned to each level or ranking.
Individual scores are summed for a total possible scores ranging from 0 (worst) to 100 (best) with higher scores indicating more independent daily living.
