A Clinical Trial to Evaluate the Safety and Efficacy of 20 ml Cerebrolysin in Patients With Vascular Dementia
- Conditions
- Vascular Dementia
- Interventions
- Drug: 0.9% Saline Solution
- Registration Number
- NCT00947531
- Lead Sponsor
- Ever Neuro Pharma GmbH
- Brief Summary
This clinical trial was performed to assess the clinical efficacy and safety of two 4 week treatment courses of daily intravenous administration of Cerebrolysin (20mL \[milliliter\] IV \[intravenous\] per day). The study was performed as prospective, randomised, double-blind, placebo-controlled, parallel group, multicentre study with 2 study groups.
Group 1: 20 mL Cerebrolysin and 100 mg (milligram) acetylsalicylic acid Group 2: Placebo (0.9% NaCl \[sodium chloride\]) and 100 mg acetylsalicylic acid The study drug was given once daily by intravenous infusion (20ml in 250ml saline solution) for 4 weeks on five consecutive days per week. This treatment regimen was repeated after a two-month treatment-free interval. Acetylsalicylic acid was given orally, once daily throughout the study duration of 24 weeks.
Altogether five clinical evaluation visits at Baseline (day 0) and at week 4, 12, 16, and 24 were necessary.

- Primary Outcome Measures
Name Time Method Change From Baseline in ADAS-cog+ (Alzheimer's Disease Assesment Scale - Cognitive Subpart) at Week 24 baseline and week 24 The ADAS-COG+ is a psychometric instrument used to evaluate memory, attention, reasoning, language, orientation and praxis. The score ranges from 0 to 85 with 85 being the worst score. A negative change indicates cognitive improvement.
CIBIC+ (Clinicians Interview-based Impression of Change) Score at Week 24 week 24 This rating scale is based on the health care provider's "general clinical impressions" with the informant input (i.e. family members). It evaluates global function and is scored from 1 (marked improvement) to 7 (marked worsening).
- Secondary Outcome Measures
Name Time Method Change From Baseline in ADAS-COG+ (Alzheimer's Disease Assessment Scale Cognitive Subpart) week 4, 12, 16 The modified Alzheimer's Disease Assessment Scale - Cognitive (ADAS-COG+) is a psychometric instrument used by a neuropsychologist that evaluates memory, attention, reasoning, language, orientation and praxis.
Change From Baseline for Original ADAS-COG week 4, 12, 16, 24 The Original Alzheimer's Disease Assessment Scale - Cognitive (ADAS-COG) is comprised of items 1-11 of the modified ADAS-COG+.
CIBIC+ Score week 4, 12, 16 The Clinician Interview-based Impression of Change (CIBIC+) score is assigned by an experienced physician familiar with the manifestations of dementia after interviewing the patient and the caregiver.
ADAS-COG+ Response week 4, 12, 16, 24 A patient with an improvement from baseline of ≥ 4 points in the ADAS-COG+ score at a particular visit is considered to have an ADAS-COG+ response at that visit.
CIBIC+ Response week 4, 12, 16, 24 A patient with a CIBIC+ score of 1 to 3 at a particular visit is considered to have a CIBIC+ response at that visit. Patients with a score of 0, indicating that the assessment was not performed, are considered to be non-responders.
CIBIS+ (Clinicians Interview-Based Impression of Severity) week 24 The Clinician Interview-based Impression of Disease Severity (CIBIS+) score is assigned by an experienced physician, familiar with the manifestations of dementia, after interviewing the patient and the caregiver.
Change From Baseline in MMSE (Mini-Mental State Examination) Score week 4, 12, 16, 24 The Mini-Mental State Examination (MMSE) is a frequently used screening instrument for clinical trials conducted in patients with Alzheimer's Disease. It evaluates orientation, registration, attention and calculation, recall and language.
Change From Baseline in ADCS-ADL (Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale) week 4, 12, 16, 24 The ADCS-ADL is a measure of functional disability. The ADCS-ADL assessment of activities of daily living is based on an interview with the caregiver.
Change From Baseline in Trail-making Test week 4, 12, 16, 24 The Trail-making test is a frequently used instrument for the assessment of executive function.
Change From Baseline in Clock-drawing Test week 4, 12, 16, 24 The Clock-drawing test is a frequently used screening instrument for dementia drug studies. It evaluates executive function of demented patients.
Combined Response, i.e. Response in ADAS-COG+ and CIBIC+ week 4, 12, 16, 24
