What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Rotigotine, extended-release microspheresDrug
Four stable dose levels of LY03003 at 14, 28, 42 and 56 mg will be evaluated. For each dose level, the stable dose will be administered once a week for consecutive 5 weeks. To improve patient's tolerability, dose upward titration will be applied to 28, 42 and 56 mg dose groups according to the following schedule:
- Patients to be enrolled to 14 mg dose group will receive 14 mg for 5 consecutive weeks.
- Patients to be enrolled to 28 mg dose group will receive 14 mg in the first week and then 28 mg in the next 5 weeks.
- Patients to be enrolled to 42 mg dose group will receive 14 mg in the first week, 28 mg in the second week and then 42 mg in the next 5 weeks.
- Patients to be enrolled to 56 mg dose group will receive 14 mg in the first week, 28 mg in the second week, 42 mg in the third week and then 56 mg in the next 5 weeks.
Placebo, extended-release microspheresDrug
Four stable dose levels of placebo at 14, 28, 42 and 56 mg will be evaluated. For each dose level, the stable dose will be administered once a week for consecutive 5 weeks. To improve patient's tolerability, dose upward titration will be applied to 28, 42 and 56 mg dose groups according to the following schedule:

What is being measured
The primary outcome is the main question the study is designed to answer.
LY03003 concentration in plasma
Measured: Days 1, 2, 4, 6, 8, 15, 22, 29, 30, 32, 34, 36, 38, 40, 43, and day 50
Secondary outcomes (2)
Frequency of adverse events
Adverse events to evaluate the safety and tolerability of LY03003
Measured: From screening up to day 50
Change from baseline to the end of the treatment period in the Unified Parkinson's Disease Rating Scale (UPDRS) part (Ⅲ) Total Score
The Unified Parkinson´s Disease Rating Scale Part Ⅲ is an accepted and validated scale for the assessment of motor function in Parkinson´s disease. Each of the 27 sub-items in the UPDRS III is measured on a scale of 0 to 4, where 0 is normal and 4 represents severe abnormalities. The total scores therefore ranges from 0 (Best score possible) to 108 (Worst score possible).
Measured: screening, baseline and day 29 and Day 50

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Rotigotine, extended-release microspheres in people with Parkinson Disease, run by Luye Pharma Group Ltd..
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 6 inclusion and 14 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 5 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
LY03003 concentration in plasma (time frame: Days 1, 2, 4, 6, 8, 15, 22, 29, 30, 32, 34, 36, 38, 40, 43, and day 50). 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 5 Aug 2019.
