Phase 1 |
Detailed Description
This is a Phase I, randomized, single-blind, placebo-controlled, multiple-ascending dose (MAD), sequential-group study in healthy Japanese (Part 1, Cohorts 1, 2, and 3) and Chinese (Part 2, Cohort 4) male subjects, conducted at a single study center. Four cohorts are planned, but one additional cohort may be enrolled based on a Safety Review Committee (SRC) decision.
The 4 multiple dose levels are planned as follows:
-
Cohort 1: Dose 1
-
Cohort 2: Dose 2
-
Cohort 3: Dose 3
-
Cohort 4: Dose 2
A randomization ratio of 3:1 (AZD4831 versus placebo) will be used.
For each cohort the study will comprise:
-
Screening Period of a maximum of 28 days.
-
A Treatment Period during which subjects are resident in the study center from the day before first dosing with the Investigational Medicinal Product (Day -1) until at least 48 hours after last dosing on Day 10; subjects will be discharged on Day 12.
-
Three Follow-up Visits on Day 14, Day 16 (±1 day), and Day 20 (±1 day).
-
A Final Follow-up Visit on Day 24 (±2 days).
Each subject will be involved in the study for 8 to 9 weeks.
