About this study
Official title: A Randomized, Multicenter, Double-Blind, Parallel, Placebo-controlled Phase 2b Clinical Trial to Evaluate the Efficacy and Safety of YN001 in Adults With Coronary Atherosclerosis
This study is designed to evaluate the efficacy and safety of intravenously administered YN001 in patients diagnosed with coronary atherosclerosis, who are receiving background therapy for cardiovascular (CV) risk factors management.
Read the detailed description
This is a multinational, multicenter, randomized, parallel, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of intravenously administered YN001 compared with placebo in participants with coronary atherosclerosis who are receiving background therapy for CV risk factors management.
A total of 456 participants are expected to be enrolled. The study will consist of a maximum 12-week screening/Baseline period, followed by a 12-week blinded treatment period, a 30-day safety follow-up, and a long-term follow-up period through Week 96 (approximately 2 years after randomization).
- Conditions

Questions about this trial
What is this clinical trial studying?
A Phase 2 study of Atherosclerosis and Coronary Artery Disease, run by Beijing Inno Medicine Co., Ltd. at 56 sites in 4 countries.
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 13 inclusion and 29 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 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 56 sites in China, United States, Canada, Australia. 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?
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 Jingmei Zhang, Master (0086 010 82599080, zhangjingmei@innovmedicine.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Relative change from baseline in coronary NCPV at Week 13 (time frame: Baseline to Week 13). 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 Nov 2026.
