About this study
Official title: The Effects of the Rivastigmine Patch on Attention and Behavior in Parkinson's Disease With Dementia (PDD)
This is an open-label study to investigate the effects of the rivastigmine patch on attention and behavior in Parkinson's disease when associated with memory and/or thinking problems. Rivastigmine (also sold under the name Exelon) is an FDA approved medication used for the treatment of mild to moderate Alzheimer's Disease (AD) and memory or thinking problems due to Parkinson's disease. Recently a rivastigmine patch was developed, which has shown similar effectiveness with fewer side effects and increased caregiver preference when compared to capsules. This is an open-label 12 week study where 15 subjects diagnosed with Parkinson's Disease who have mild to moderate memory and/or thinking complaints will be treated with the rivastigmine patch at UCSF. This study also analyzes the mechanism by which the rivastigmine patch works in people with Parkinson's disease and memory and/or thinking problems.
Read the detailed description
Participation in this study requires four visits: a screening visit to ensure eligibility, an initial/baseline visit where the medication is distributed at a dosage lower than the optimal recommended dosage, a four week follow-up visit where the dosage of the medication is increased to the optimal amount, and a final twelve week follow up visit.
- In the screening visit the patient will undergo a neurological exam (including a review of their medical history and short physical exam), electrocardiogram ( a painless procedure that measures electrical activity of your heart), cognitive testing (such as memory and thinking tests), and a blood draw.
- At the Baseline/Initial visit the patient will receive a brief physical exam, additional cognitive testing, and an MRI scan. Afterwards, the study drug will be distributed.
- At the four week follow up visit the patient will be asked to do some abbreviated cognitive and neurological testing and the study drug will be re-distributed at the target dosage.
- At the final twelve week visit the patient will receive additional cognitive and neurological testing, and an MRI scan.
- Study compliance and adverse events will be reviewed every two weeks throughout the study, whether in person or over the phone.

What is being measured
The primary outcome is the main question the study is designed to answer.
Resting State Functional Activity Change From Baseline to 12 Weeks
Fractional amplitude of low frequency fluctuations (fALFF) was used to measure brain activity. This metric is derived from task-free functional magnetic resonance imaging (fMRI) and represents the power of regional spontaneous and intrinsic brain activity at the local, voxel-wise level while the subject is at rest. More specifically, the amplitude of low-frequency fluctuations (ALFF) is the total power in the low-frequency range, and fALFF is calculated by dividing ALFF by the total power across all measurable frequencies. Whereas ALFF values increase near blood vessels and cerebrospinal fluid (CSF), likely due to pulsations in those areas, fALFF is less susceptible to artifactual signals. We measured change in these ratio scores post-treatment minus baseline and present in z-score units.
Measured: Baseline and 12 weeks
Pre-post Change in Continuous Performance Test of Attention (Median Reaction Time)
On the Continuous Performance Test (CPT), subjects press the spacebar quickly when they see a target image (a white star; 150 trials), and withhold response when they see a non-target image (5 randomly sampled white shapes; 150 trials). The inter-stimulus interval is randomly sampled from 1.5s, 2.5s, or 4s. Performance is measured by the median reaction time (milliseconds) on accurate target trials.
Measured: Baseline and 12 weeks
Secondary outcomes (1)
Pre-post Change in Montreal Cognitive Assessment
The Montreal Cognitive Assessment (MoCA) was used as measure of global cognitive function. Total scores range from 0 (worst) to 30 (best).
Measured: Baseline and 12 weeks

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?
Yes. Results are posted in the registry (first posted 26 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Resting State Functional Activity Change From Baseline to 12 Weeks (time frame: Baseline and 12 weeks). 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 NCT00988117, 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 26 Feb 2014.
