About this study

Official title: A Phase 2 Clinical Study of KW-6500 (Apomorphine Hydrochloride) in Patients With Parkinson's Disease

The purpose of this study is to evaluate the efficacy of KW-6500 versus placebo when administered as a subcutaneous injection at the individualized maintenance dose level in an OFF state in Parkinson's disease patients with motor response complications on levodopa therapy.

Read the detailed description

The efficacy of KW-6500 as a subcutaneous injection at the individualized maintenance dose level (1 mg to 6 mg per dose) when used in combination with domperidone (30 mg/day) will be evaluated in comparison with that of placebo in Parkinson's disease patients with motor response complications on levodopa therapy. The maintenance dose level for each subject will be determined using a titration scheme in 1 mg increments.

Being tested
apomorphine hydrochloride

What participants receive

  • apomorphine hydrochlorideDrug

    Also called KW-6500

    Apomorphine hydrochloride (started at 1 mg and titrated to a maximum of 6 mg) is subcutaneously administered.

What is being measured

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

  1. The change (response ratio, raw score change, percent score change) in UPDRS (Unified Parkinson's Disease Rating Scale ) Part 3 score at the maintenance dose level

    Measured: At 20 minutes after administering KW-6500 or placebo

Secondary outcomes (1)
  1. The incidence of adverse events/adverse drug reactions and their nature

    Measured: 1 week after starting treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing apomorphine hydrochloride in people with Parkinson's Disease, run by Kyowa Kirin Co., Ltd. at 4 sites in Japan.

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 10 inclusion and 21 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 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Japan. 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 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 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?

The change (response ratio, raw score change, percent score change) in UPDRS (Unified Parkinson's Disease Rating Scale ) Part 3 score at the maintenance dose level (time frame: At 20 minutes after administering KW-6500 or placebo). 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 Aug 2020.
