Study Details

Study Description

Brief Summary

AZD9977 is an oral, selective mineralocorticoid receptor (MR) modulator. AZD9977 is a partial antagonist and partial agonist in reporter gene assays and has a different interaction pattern with the MR compared to eplerenone. This study will assess the safety, tolerability and pharmacokinetics (PK) of AZD9977, following oral administration of single and multiple ascending dose of AZD9977.

Heart Failure	Drug: AZD9977 Drug: Placebo	Phase 1

Detailed Description

This will be a Phase I, randomized, single-blind, placebo-controlled, single and multiple ascending dose sequential-group design study. The study will be conducted in healthy Japanese participants and performed at a single study center. Fourth-five healthy Japanese participants are planned to be included in the study and up to 5 additional participants may be enrolled into the study if replacement participants are needed.

Three cohorts consisting of 9 participants each will participate in the study. Depending on the findings, up to 2 additional cohorts may be added if the Safety Review Committee (SRC) considers it necessary to repeat a dose level or if additional dose steps are required.

Within each cohort, 6 participants will be randomized to receive AZD9977 and 3 participants randomized to receive placebo.

Each participant will receive AZD9977 at the selected dose level or placebo on Day 1 and from Day 3 to 9, with single dose on Day 1 and Day 9 and twice a day (BID) dosing on Day 3 to Day 8. No dose will be given on Day 2.

The study will comprise of:

A Screening Period of maximum 28 days;
A Treatment Period during which participants will be resident at the Clinical Unit from the day before Investigational Medicinal Product (IMP) administration (Day -1) until at least 48 hours after IMP administration; discharged on Day 11, and
A Follow-up Visit within 5 to 7 days after the last IMP dose. Each participant will be involved in the study for approximately 6 weeks.
