About this study

Official title: Efficacy of Amantadine for Gait Dysfunction and Gait Freezing in Patients With Parkinson's Disease

The purpose of this study is to explore the efficacy of the drug Amantadine for the treatment of freezing of gait in patients with Parkinson's Disease. The investigators hypothesize that amantadine is useful for management of freezing of gait in subjects with Parkinson's Disease.

Read the detailed description

Subjects who meet the eligibility requirements for the study will be randomized to Amantadine versus a matching placebo.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AmantadineDrug

    Also called Symmetrel

    Amantadine 100mg daily, for a week, if it is tolerated Amantadine will increase to 1 tab twice a day. Amantadine will then be administered orally twice daily in the morning with breakfast and at noon with lunch (AM and NN).

  • PlaceboDrug

    Also called Sugar Pill

    Sugar Pill

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Timed Up and Go (TUG) - ON Usual Medication

    This is a walking assessment. The subject will begin in the seated position, stand up, walk 7 meters, turn around, and sit back down. The entire process from leaving the chair to returning to the chair will be timed. Also, the Timed Up and Go (TUG) will be done both in the ON and OFF states.

    Measured: Baseline, change at 4 weeks

  2. Timed Up and Go (TUG) - OFF Usual Medication

    This is a walking assessment. The subject will begin in the seated position, stand up, walk 7 meters, turn around, and sit back down. The entire process from leaving the chair to returning to the chair will be timed. Also, the Timed Up and Go (TUG) will be done both in the ON and OFF states.

    Measured: Baseline, change at 4 weeks

Secondary outcomes (9)
  1. Modified Timed Up and Go (mTUG)

    The subject sits in the chair approximately 3 1/2 meters away from doorway with the door closed. Subject then stands up and walks one meter to a 40cm X 40cm box taped on the floor. Within the box the patient turns clockwise (360 degrees), then turns counterclockwise (360 degrees). Walk to open the door and walk through the doorway, turn around and return to the chair. Modified Timed Up and Go (mTUG) completed in three components including walking the course without additional tasks, carrying a tray with a cup of water, and counting backwards from 100, in both ON and OFF state.

    Measured: Baseline, change in 4 weeks

  2. Analysis of Motor Functioning Using the Parkinson's Home Diaries

    Subject will record motor activity as OFF, ON (mobility improved) or asleep on the diary every half hour for two days. Subjects further define ON time according to dyskinesia categories "none", "non-troublesome" or "troublesome." The home diaries are used as an evaluation measure of the intervention by assessing the change in off time and change in on time with troublesome dyskinesia. The difference in time experiencing dyskinesia while ON meds relative to the time OFF meds at baseline and at 4 weeks is compared.

    Measured: Baseline, change in 4 weeks

  3. Freezing of Gait Questionnaire

    A questionnaire that is used to assess the likelihood of the subject freezing in a number of different scenarios.

    0=No freezing of gait to 24=severe freezing of gait

    Measured: Baseline, change in 4 weeks

  4. Clinical Global Impression (CGI)

    Global Improvement is the second scale in the clinical global impression (CGI). Total overall improvement is judged by whether or not, in the judgment of the assessor, the improvement is entirely due to the drug treatment. It is also a 1-7 point weighted scale, going from "very much improved" (1) to "very much worse" (7). A zero score is assigned if the score is not assessed.

    Measured: 4 weeks

  5. Parkinson's Disease Questionnaire-39 (PDQ-39)

    The Parkinson's Disease Questionnaire-39 (PDQ39) is a copyrighted instrument to assess symptoms of Parkinson's disease (PD) with 39 questions relating to mobility, activities of daily living, emotional well-being, social support, cognition, communication and bodily discomfort. The test asks subjects to rate each question regarding their Parkinson's disease symptoms over the past month. (range 0 to 100, lower scores reflect better quality of life)

    Measured: Baseline, week 4

  6. Gait Analysis Testing

    Use of an accelerometer such as Motorola Droid and wireless acceleration sensors to record gait parameters step time, walking speed, and cadence during the timed up and go (TUG) and modified timed up and go (mTUG) components. The sensors will be attached to the subject's legs and trunk using Velcro straps. The accelerometer will be held or clipped onto the subject in order to measure his or her acceleration. This is done within clinic and during the visit time.

    Measured: Baseline, week 4, week 7, week 11

  7. Fatigue Severity Scale (FSS)

    A questionnaire used to discriminate between Parkinson Disease (PD) patients with fatigue and those without fatigue. Range 9 to 63, higher scores indicate greater fatigue severity.

    Measured: Baseline, change in 4 weeks

  8. Number Who Completed Medication as Randomized

    Tolerability analysis as determined by the number of subjects completing each arm of the study.

    Measured: week 4

  9. Number of Participants With Drug Safety Reports

    Analyzing the safety of the medication, Amantadine. Data regarding the medication will be collected from the patient on each visit including any adverse events since the last visit, frequency and severity of falls. This is done in order to determine the safety of Amantadine.

    Measured: Week 4

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Amantadine in people with Parkinson's Disease, run by Northwestern University at 1 site in United States.

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 8 inclusion and 10 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: stopped early, as of the sponsor's last update on 13 Nov 2019. 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 United States. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 13 Nov 2019). 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?

Timed Up and Go (TUG) - ON Usual Medication (time frame: Baseline, change at 4 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?
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 13 Nov 2019.
