About this study

This study is to understand the efficacy on language and cognitive function in Down syndrome patients who take Rivastigmine.

Read the detailed description

Down syndrome (DS) is the most common cause of mental retardation due to chromosome anomaly. Besides defects in cognition, DS patients after 30 yeas old will have early dementia. Etiology of early dementia is known to be related with APP gene dosage triplication that is similar to the neuropathological change in Alzheimer disease (AD). It has been known that the cognitive degeneration in AD is related with decrement of cholinergic neurons in the brain. And the clinical improvement or delay in degeneration of cognitive function after utilization of cholinesterase inhibitor had been observed in mild to moderate AD patients. In DS brain, it has been also noted to be lower acetylcholine, supporting the relationship of pathology between DS and AD. Since 1999, Kishnani et al started to treat adult DS patients with cholinesterase inhibitor (Donepezil). Data showed the improvement of cognition and life quality in DS patients with dementia. Recently, data showed the low cholinergic neuron in DS brain might be a cause of cognitive dysfunction in DS. Therefore, early treatment of cholinesterase inhibitor in DS patients had been proposed to alleviate cognitive dysfunction. Since 2004, Kishnani et al started to treat DS children with Donepezil and Rivastigmine. Some patients showed improvement of language ability, memory, and attention. We are going to conduct a randomized, double-blind, placebo-controlled, crossover design, 12-month trial. Subjects who are enrolled in this study will be randomized into two groups. Each group will receive Rivastigmine and placebo in different order for 6 months. Neuropsychological assessment including Vineland Adaptive Behavior Scales and NEPSY will be evaluated before and after medication. Through this, we wish to understand the efficacy of this drug in the role of improving cognitive functioning in our patients.

Questions about this trial

What is this clinical trial studying?

A study testing Rivastigmine in people with Down Syndrome, run by National Taiwan University Hospital at 1 site in Taiwan.

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 5 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 28 Nov 2012. 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 Taiwan. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Scores of Vineland Adaptive Behavior Scales (VABS), Scores of WISC digit span, Scores of Leiter-R Forward memory , Scores of PPVT, (time frame: at 24, and 54 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Nov 2012.
