Testing UDP-003 for safety and effectiveness in healthy individuals and patients with heart conditions
Official title: A Double Blind, Placebo-controlled Study in Healthy Participants to Investigate the Safety, Pharmacokinetics and Pharmacodynamics of Single and Multiple Ascending Doses of UDP-003 and Followed by an Open-label Multiple-dose Patient Cohort
Run by Cyclarity Therapeutics, Inc. · NCT06813339 · Data updated 2026-11-12
This study is testing a new drug called UDP-003 to see if it's safe and effective for both healthy people and those with heart conditions, specifically looking at its ability to reduce plaque buildup in the arteries.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include healthy adults aged 18 to 55 and adults aged 40 to 79 with a history of acute coronary syndrome at least 12 months post-event.
✕Probably not a fit
Patients with significant comorbidities or those not meeting the eligibility criteria may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the safety and pharmacokinetics of UDP-003 in both healthy participants and patients with acute coronary syndrome. The study is designed as a randomized, double-blind, placebo-controlled trial and consists of three parts: single ascending doses in healthy participants, multiple ascending doses in healthy participants, and multiple doses in patients diagnosed with acute coronary syndrome. The trial will assess the drug's potential efficacy in reducing plaque burden in patients with cardiovascular disease. Safety data will be reviewed before escalating doses in the trial.
Why it matters
Potential benefit: If successful, this study could lead to new treatment options for reducing plaque burden in patients with atherosclerotic cardiovascular disease.
How similar studies have gone: While this approach is novel in its specific application, similar studies have shown promise in evaluating new treatments for cardiovascular conditions.

Inclusion Criteria All Participants: 1. Participant understands study procedures and provides written informed consent for the trial. 2. Participant is able to comply with the protocol and the assessments therein. Healthy Participants (SAD and MAD cohorts): 1. Healthy adult males and females, 18 to 65 years of age (inclusive) at the time of screening. 2. Adult males and females of body mass index (BMI) ≥ 18 and ≤ 32 kg/m² and body weight ≥ 50 and ≤ 120 kg. 3. Social smoking of less than 10 nicotine-containing products per month is acceptable. Absence of tobacco or nicotine containing product (including smoking cessation products) use, for a minimum of 2 weeks prior to dosing is required and will be confirmed by a negative cotinine test at check-in (one retest allowed at the discretion of the investigator). 4. Medically healthy with relevant renal parameters tests not exceeding 1.5 X the upper limits and no clinically significant screening results (e.g., laboratory profiles, medical history, vital signs, ECGs, physical examination) as deemed by the Principal Investigator; one retest is permitted at investigator discretion. Participants with ACS (MD Patient cohort): 1. Adult males and females, 40 to 79 years of age (inclusive) at the time of screening, diagnosed with acute coronary syndrome (ACS), at least 12 months post event (NSTEMI or unstable angina). 2. Adult males and females of body mass index (BMI) ≥ 18 3. Medically stable with no clinically significant screening results (e.g., laboratory profiles including relevant renal parameters and liver function tests, medical history, vital signs, ECGs, physical examination) as deemed by the Principal Investigator. 4. Participants on a stable regimen and dose of ACS treatment including statins, anticoagulants, blood thinners, anti-platelets or other standard of care for 3 months prior to screening and for whom no change in this treatment is planned during the participation in the study.
