Donepezil in Chronic Poststroke Aphasia: a Randomized Controlled Trial
A Phase 4 study testing Donepezil in people with Stroke and Aphasia, run by Gabinete Berthier y Martínez at 1 site in Spain.
Trial summary
Aphasia (impairment of language function due to brain damage)may be treated with speech-language therapy and drugs. Several drugs have been studied but with limited success. Recent data suggest that the neurotransmitter acetylcholine may be reduced in brain damaged subjects and that drugs that stimulates acetylcholine… Read more about this study

About this study
Official title: Treatment With Donepezil of Chronic Aphasia and Sensorimotor Deficits Associated to Cerebrovascular Accidents: a Double-Blind,Placebo-Controlled, Randomized Parallel Trial.
- Aphasia (impairment of language function due to brain damage)may be treated with speech-language therapy and drugs. Several drugs have been studied but with limited success.
- Recent data suggest that the neurotransmitter acetylcholine may be reduced in brain damaged subjects and that drugs that stimulates acetylcholine activity may help recovery of aphasic deficits particularly when paired with speech-language therapy.
- Recent evidence indicates that medicaments acting on the neurotransmitter acetylcholine may promote improvement of aphasic deficits and our previous open-label study of donepezil in post-stroke aphasia showed benefits in all patients and observed benefit were long-lasting (6 months).This study will test the safety and efficacy of donepezil (an agent acting on acetylcholine)in subjects with stroke-related chronic aphasia (more than 1 yr of evolution).
Read the detailed description
- Prior clinical information of donepezil treatment of post-stroke aphasia comes from single-case studies, small case-series and an open-label study. In addition, an extension phase of a small open-label study also suggest that the efficacy of donepezil in chronic post-stroke apahsia is maintained at long-term follow-up. These data collectively suggest that in post-stroke donepezil is effective and well-tolerated with a limited potential for causing clinically significant interactions when prescribed with other medications. However, these results are preliminary and should be judged parsimoniously until randomized controlled trials will be performed.Moreover, recent data by our group also showed that donepezil may improve sensorimotor deficits (hemiparesis)in some patients.
- The use of acetylcholinesterase inhibitors such as donepezil in post-stroke may be justified because in vivo and postmortem studies have shown that patients with vascular dementia and lesions in subcortical and cortical structures have deficient cholinergic neurotransmission that results from interruption of cholinergic pathways linking the basal forebrain with the cerebral cortex, including the perisylvian language area.In addition, two large-scale randomized controlled trials in patients pure vascular dementia and vascular cognitive impairment found that donepezil was significantly superior to placebo on cognition, global function and activities of daily living.And the most noticeable benefits of donepezil over placebo at doses of 5-mg and 10-mg were found on the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog/11), an assessment instrument highly reliant upon language variables (6 out of 11 items).
- We evaluated the efficacy of donepezil in patients with chronic aphasia associated with stroke.This is a 20-week, randomized, placebo-controlled, double-blind parallel study that enrolled aphasic patient with more than one year of evolution. During the study all patients continued receiving two hours weekly of conventional speech-language therapy. Patients were randomized in an 1:1 ratio to donepezil, 5-mg/day, for the first 4 weeks, followed by forced dose escalation to 10-mg/day thereafter (n =13), or placebo (n = 13) and then a 4 week washout period. The primary efficacy measures were the Aphasia Quotient (AQ) of the Western Aphasia Battery and the Communicative Activity Log. Secondary efficacy measures included selected subtests of the Psycholinguistic Assessment of Language Processing in Aphasia that examined phonological and lexical-semantic domains and the Stroke Aphasia Depression Questionnaire.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Donepezil in people with Stroke and Aphasia, run by Gabinete Berthier y Martínez at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Sep 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Language function (overall aphasia severity). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00196690, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Sep 2005.
