EARLY_PHASE1

Placebo-controlled Study of Single and Multiple Ascending Doses of UDP-003 in Healthy Human Participants and Patients

Sponsor: Cyclarity Therapeutics, Inc.

View on ClinicalTrials.gov

Summary

The goal of this clinical trial is to learn if UDP-003 is safe in healthy human participants and patients, assess the pharmacokinetics (PK)/pharmacodynamics (PD) of UDP-003 in healthy human participants and patients and its potential efficacy in patients. Researchers will compare UDP-003 to a placebo in a blinded manner. This first in human, randomised, double-blind, placebo-controlled, prospective, single-centre trial with a modular dose-finding design will be conducted in 3 parts: * Part 1: 6 cohorts of 6 healthy participants receiving Single Ascending Doses (SADs), * Part 2: 3 cohorts of 12 healthy participants receiving Multiple Ascending Doses (MADs) (6 doses over 16 days), * Part 3: 1 cohort of 12 participants diagnosed with acute coronary syndrome (ACS; non-ST elevation myocardial infarction \[NSTEMI\] or unstable angina) at least 12 months post-event receiving multiple doses (6 administrations of the 25 mg/kg dose over 16 days). The planned duration of the study for each participant will be: * 4 weeks for SAD Participants (1-day treatment period, 4-week safety follow-up) * 6 weeks for MAD Participants (16-day treatment period,4-week safety follow-up) * 28 weeks for MD Patients (6-week treatment period, 6-month safety follow-up) Prior to participants being randomised to panels of increasing doses, all safety data will be reviewed for completed panels.

Interventions

DRUG

UDP-003

The UDP-003 finished product is clear, colourless to yellow liquid that is intended to be a sterile solution for IV bolus push administration in sterile water at a concentration of 300 mg/mL.

OTHER

Placebo

Placebo will be provided as a sterile clear, colourless solution formulated to match viscosity of the UDP-003 solution.

Inclusion Criteria: (Healthy Participants (SAD and MAD cohorts)): * Healthy adult males and females, 18 to 55 years of age (inclusive) at the time of screening. * 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): * 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). * 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. * 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. Exclusion Criteria: (Healthy Participants (SAD and MAD cohorts)): * History or presence of significant cardiovascular, pulmonary, hepatic, renal, haematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological, or psychiatric disease as deemed by the Principal Investigator. * History of myocardial infarction (MI), transient ischemic attack (TIA), stroke, or familial history of coronary artery disease or first-degree heart attack below the age of 60. * Any clinically significant ECG abnormality at Screening * Diabetic participants (Patients (MD cohort): * Percutaneous coronary intervention or diagnostic angiogram planned after screening. * Documented episode of post-MI pericarditis in the 3 months before enrollment. * Ongoing heart failure as defined by Class IV New York Heart Association * History or presence of significant pulmonary, hepatic, renal, haematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological, or psychiatric disease. * Ongoing infection or febrile illness. * Ongoing atrial fibrillation or flutter. * History of MI, TIA, or stroke diagnosed within the 12 months prior to screening. * History of or planned coronary artery bypass grafting. * Any cardiac intervention or cardiac hospitalization in the past 12 months * Any clinically significant ECG abnormality at Screening. * Participants with contraindications to CTA.
