简要总结

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 up to 9 evaluable 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 6 weeks).

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)
180 Days 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.

详细描述

This trial's objective will be to collect the preliminary clinical safety and clinical pharmacology data. The study objective in the patient cohort is obtaining preliminary information on the safety of UDP-003 in those carrying a detectable plaque burden and obtaining preliminary indication of efficacy in respect to reducing the plaque burden.

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 SADs,
Part 2: 3 cohorts of 12 healthy participants receiving 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 6 weeks). The SAD part will include healthy participants randomised to either active or placebo with a 2:1 ratio (24 active, 12 placebo) and the MAD parts with a 3:1 ratio (27 active, 9 placebo), in addition to up to 12 MD patient cohort receiving UDP-003.

Prior to participants being randomised to panels of increasing doses, all safety data will be reviewed for completed panels. Within each dose group in the SAD portion of the study, sentinel dosing will be implemented wherein 2 participants (1 active, 1 placebo) will be dosed at least 24 hours before the remaining participants in the cohort. Dosing in the MAD portion of the study will commence only after the Data Safety Monitoring Committee (DSMC) reviews the safety data from the 5th (20 mg/kg) SAD cohort.

Investigational Products A. UDP-003, formulated as a sterile solution for injection, 300 mg/mL. Volume of administration is weight dependent and target doses are 1-25 mg/kg.
