About this study

Official title: Comparison of Continuous and Pulsatile Apomorphine Administration in Parkinson's Disease Complicated by Levodopa-induced Dyskinesia

The purpose of this study is to compare the effects of apomorphine, given by two different methods, to determine how best to manage dyskinesias.

Read the detailed description

Levodopa is a drug that can be taken by mouth, and improves the symptoms of Parkinson's disease (PD). However it can eventually cause involuntary movements called dyskinesia and motor fluctuations-fluctuations in the control of symptoms, often referred to as "off" and "on." Apomorphine is a drug that works as well as levodopa, but does not work if taken by mouth.

The purpose of this study is to compare the effects of apomorphine in people with PD who have levodopa-induced motor fluctuations and dyskinesias. In the trial, researchers will compare the effects of apomorphine administered by subcutaneous bolus injections (pulsatile) and by ambulatory infusion pumps (continuous) in 24 people with PD, for 6 months.

After an initial screening, potential participants will undergo a test to verify that they can tolerate and respond to apomorphine. Those who meet all of the requirements will be randomized to receive the study drug via injections (shots) using an injector pen or a portable infusion pump. Apomorphine will be given either continuously using the portable pump during the waking day or intermittently by injection, for 6 months. The pump will be carried on a belt and connected by a tube to a small needle under the skin. Injections of apomorphine under the skin will be self-administered by the participants or administered by friends or family members using injector pens.

After 6 months, the effects of apomorphine use will be assessed by measuring how the participants respond to levodopa and by measuring their symptoms during the course of the study. Participants will be followed initially every week, then biweekly, and then monthly in an outpatient clinic for 6 months. During this time, they may receive adjustments of apomorphine doses as well as doses of other antiparkinson medications.

What participants receive

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

  • ApomorphineDrug

    Also called Apokyn, apomorphine, apo-go pump

    Participants in both arms will receive the study drug apomorphine for 6 months. One group will receive it continuously using a portable pump during waking hours, and the other group will receive it intermittently by bolus injections. The continuous delivery group will receive up to 100 mg apomorphine per 24 hours, delivered subcutaneously by ambulatory pump. The intermittent delivery group will receive up to 5 subcutaneous injections totaling up to 20 mg daily.

What is being measured

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

  1. Change in dyskinesia severity and duration during the levodopa infusion, measured with a clinical rating scale during two-hour levodopa infusion

    Measured: at baseline and after 6 months

Secondary outcomes (3)
  1. Improvement in motor performance, measured as change in tapping speed during levodopa infusion

    Measured: at baseline and after 6 months

  2. Improvement in "on" time, as measured by subject diaries

    Measured: at baseline and after 6 months

  3. Reduction in levodopa and adjunct drug use

    Measured: at baseline and after 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Apomorphine in people with Parkinson's Disease, run by Oregon Health and Science 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 5 inclusion and 4 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: withdrawn, as of the sponsor's last update on 2 Nov 2018. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 was withdrawn before enrolling participants, so there are no results.

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?

Change in dyskinesia severity and duration during the levodopa infusion, measured with a clinical rating scale during two-hour levodopa infusion (time frame: at baseline and after 6 months). 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 NCT00758368, which also lists 3 linked publications.

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 2 Nov 2018.
