- Lead Sponsor
- AstraZeneca
- Brief Summary
The purpose of the study is to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple ascending doses of AZD4954 in healthy participants with or without elevated Lipoprotein(a) (Lp\[a\]) levels.
- Detailed Description
This is a first time in human, placebo-controlled, single and multiple ascending dose (SAD and MAD) study in healthy male and female (of non-childbearing potential) participants (Part A) or healthy participants (of non-childbearing potential) with elevated Lp(a) levels (≥ 30 mg/dL; Part B).
The study consists of 2 parts: Part A (SAD) and Part B (MAD).
Part A of the study will consist of Part A1 and Part A2, comprising:
* A Screening Period of maximum 28 days.
* Admission to study site (Day -1).
* A Treatment Period (Day 1 to Day 15 at the study site) with a single dose of AZD4954 or placebo on Day 1.
* A Follow-up Visit within 26 to 30 days after the IMP dose for all cohorts (Day 29 ±2 days).
Part B of the study will comprise:
* A Screening Period of maximum 28 days.
* Admission to study site (Day -1).
* A Treatment Period during which participants will receive either AZD4954 or placebo once daily for 21 days (Day 1 to 21) in the global MAD cohorts and for 14 days (Day 1 to 14) in Japanese MAD cohorts.
* A Follow-up Visit within 26 to 30 days after the last IMP dose (Day 42 ±2 days).
