A Study to Assess the Reaction of Body for Four Different Formulations of AZD9977 (Part A) and Influence of Food and Lower Dose of a Selected Formulation (Part B) in Healthy Male Subjects

Study Overview
=================
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 pharmacokinetics (PK) of four different Formulations of AZD9977 (Part A) and influence of food and lower dose of a selected formulation (Part B) in healthy male subjects.

Detailed Description
-----------------
This study will be a randomized, open-label, single-centre crossover study in healthy male subjects. The study is divided into 2 parts, Part A and Part B. The subjects will participate in both Part A and Part B. Part A will be a 4-way cross-over study comparing the PK of AZD9977 as a reference capsule and 2 different capsule formulations and a tablet formulation under fasting conditions. Treatment A: Reference, AZD9977 capsule Treatment B: AZD9977 HDL capsule Treatment C: AZD9977 ODL capsule Treatment D: AZD9977 tablet In Part B, based on the interim results in Part A, 1 of the formulations will be selected and evaluated at the 300 mg dose level under fed conditions. The same formulation will also be evaluated under fasting conditions at a lower dose level (50 mg). The first dose tested in Part B will be the 50 mg (fasted) dose, followed by the 300 mg (fed) dose. In Part A, subjects will be resident from 1 day before dosing (Day -1 of Treatment Period 1) with AZD9977 until 48 hours post-final-dose (Day 3 of Treatment Period 4). Subjects will return to the unit for Part B at least 48 hours (and up to 5 weeks) after completion of Part A. In Part B, subjects will be resident from 1 day before dosing (Day -1 of Treatment Period 1) with AZD9977 until 48 hours post-final-dose (Day 3 of Treatment Period 2). Subjects will return to the unit for a final study visit 5-7 days post-last-dose for a Follow up Visit. Each subject will be involved in the study for approximately 12 weeks (including approximately 4 to 5 weeks for the interim analysis). Twelve subjects will initially be randomized to ensure at least 8 and 6 evaluable subjects at the end of the last treatment period for Part A and Part B respectively.
