A Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AZD4144 as Well as the Impact of AZD4144 on the Pharmacokinetics of Rosuvastatin and Furosemide in Healthy Participants

This study consists of 3 parts: Part A, Part B and Part C. This study will compare the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of AZD4144 with placebo in healthy participants, in Part A and Part B. Part C of this study will investigate the possibility of drug-drug interaction (DDI) between IV AZD4144 and oral rosuvastatin and furosemide by evaluating the PK of rosuvastatin and furosemide when administered alone and in combination with single IV dose of AZD4144

This is a Phase I, randomized study in healthy participants and consists of 3 parts; Part A, Part B and Part C. Part A and B are single-blind, placebo-controlled with single ascending dose (SAD) and multiple ascending dose (MAD) sequential group design, respectively. Part C is an open-label, 2-period, 2-sequence, cross-over design study. Part A and B of the study will assess the safety, tolerability, PK, and PD of AZD4144 solution for infusion compared with placebo while Part C will investigate the possibility of DDI between IV AZD4144 and oral rosuvastatin and furosemide by evaluating the PK of rosuvastatin and furosemide when administered alone and in combination with single IV dose of AZD4144

The study will comprise of:

* A screening period of maximum 28 days.
* A residential period which lasts from,

  * Day -1 to Day 4 (single dose on Day 1) for Part A
  * Day -1 to Day 15 (dosed on days 1, 4-12) for Part B
  * Day -1 to Day 3 (dose on Day 1) and Day 9 to Day 12 (dose on Day 10) for Part C
* A final follow-up visit,

  * On Day 10+3 for Part A
  * On Day 20+3 for Part B and C
