About this study
Official title: A Phase Ⅰ, Randomized, Double-blind, Placebo-controlled, Single Dose Ascending Study to Assess the Safety, Tolerability, and Pharmacokinetics of LPM787000048 Maleate Sustained-release Tablet (LY03020) in Chinese Healthy Adult Subjects
This is a single-center, randomized, double-blind, placebo-controlled, ascending single oral dose study to assess the safety, tolerability, and pharmacokinetics of LY03020 in Chinese healthy adult subjects.
Read the detailed description
The study will set 2.5mg, 5mg, 10mg, 20mg, 40mg, 60mg, 80mg and 100mg, a total of 8 dose groups. Qualified subjects were enrolled in site at D-1 ( 1 day before administration ) and randomized.The subjects should fast for at least 10 hours before medication administration, with no restrictions on water intake. The subjects will be required to orally take LY03020 or a placebo on an empty stomach upon waking on D1 (the day of medication administration). From D1 to D7, they will undergo safety assessments and PK biological sample collection.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing LY03020 in people with Schizophrenia and Alzheimer's Disease Psychosis, run by Luye Pharma Group Ltd. at 1 site in China.
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 3 inclusion and 8 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 29 May 2025. 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 China. 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 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?
Frequency of adverse events (AEs) (time frame: up to144 hours). 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 29 May 2025; AzTrials last refreshed its copy on 7 Nov 2026.
