About

This study will assess the safety, tolerability, and pharmacokinetic (PK) of AZD5462 following single ascending dose (SAD) and multiple ascending dose (MAD) administration in healthy male and female participants and healthy participants of Japanese descent.

Full description

This Phase I, First in Human (FIH), randomized single-blind, placebo-controlled study will consist of 2 parts (Part A and Part B) with an interleaved study design.

Part A of the study will be a sequential SAD design with 5 dose levels planned to be investigated across 8 cohorts, of which 3 cohorts will solely comprise of participants of Japanese descent. Within each cohort, 6 participants will be randomized to receive AZD5462 and 2 participants randomized to receive placebo.

Part B of the study will be a sequential MAD design with 4 dose levels of AZD5462 planned to be investigated across 5 cohorts, of which 1 cohort will comprise solely of participants of Japanese descent. Within each cohort 6 participants will be randomized to receive AZD5462 and 2 participants randomized to receive placebo.

The duration for participants randomized to Part A of the study is 5 to 6 weeks, and for Part B, 6 to 7 weeks.
