About this study
Official title: A Phase I Clinical Study Evaluating the Safety, Tolerability, Pharmacokinetics of a Single Oral Dose of VV261 Tablets in Chinese Healthy Volunteers
This is a randomized, double-blind, placebo-controlled, single ascending-dose study to evaluate the safety, tolerability and pharmacokinetics characteristics of VV261 tablets in healthy adults.
Read the detailed description
The study is designed to enroll 58 volunteers. The pilot study is an open-labelled study where both volunteers receive 5 mg VV261 tablets. The formal study, conducted as a double-blind study, comprise 7dose groups with 8 volunteers (both sexes) each. Volunteers will be randomly assigned to receive either the VV261 tablets or placebo in a ratio of 6:2. The formal study's dose groups are designed as 20 mg, 50 mg, 150 mg, 300 mg, 500 mg, 750 mg, and 1000 mg. Based on observed tolerability and safety data or obtained pharmacokinetic data, adjustments are allowed at all dose levels in the clinical trial.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing VV261 5mg group, VV261 20mg Group and VV261 50mg group in people with Healthy Volunteers, run by Vigonvita Life Sciences 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 5 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: looking for participants now, as of the sponsor's last update on 3 Mar 2026. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Huaqing Duan (18061926005, huaqing.duan@vigonvita.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cmax (time frame: 48 hours after administration]). The study lists 10 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 3 Mar 2026.
