Study Overview
=================
Brief Summary
-----------------
A study to assess the relative bioavailability and safety of different formulations of AZD4831 in fasted state in healthy volunteers.

Detailed Description
-----------------
This study will be a randomized, open-label, 2-period, 2-treatment, single-dose, single-center, crossover study conducted at a single Clinical Unit. A total of 30 healthy male and female participants will be randomized to ensure that at least 26 participants are evaluable . The study will comprise of: A Screening Period of maximum 28 days. Period 1: single oral dose AZD4831 Formulation A or B on Day 1. Period 2: single oral dose AZD4831 Formulation A or B on Day 1. A final Follow-up Visit after the last administration of Investigational medicinal product (IMP) (14 days [+ 3 days] post final dose). There will be a minimum washout period of at least 14 days from the first dose of AZD4831. Participants will receive single doses of AZD4831 (2 different formulations) on 2 occasions under fasted conditions. Participants will be given the following treatments and randomly assigned to the treatment sequence(s): AB, BA Treatment 1 (Reference), AZD4831 Formulation A, oral dosage form), fasted. Treatment 2 (Test), AZD4831 Formulation B, oral dosage from), fasted.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Sequence 1 (Formulation A + Formulation B)<br>Participants will receive a single oral dose of Treatment 1: Formulation A followed by a washout period of at least 14 days from first dose of AZD4831. After the washout period, participants will receive a single oral dose of Treatment 2: AZD4831 Formulation B. | Drug: AZD4831<br>* Participants will receive a single oral dose of AZD4831 Formulation A Or a single oral dose of AZD4831 Formulation B on Day 1 Period 1. Depending on what Formulation was received on Day 1 Period 1, participants will receive either a single oral dose of AZD4831 Formulation A Or a single oral dose of AZD4831 Formulation B on Day 1 of Period 2. Each period lasts for 8 days.<br>|
| Experimental: Sequence 2 (Formulation B + Formulation A)<br>Participants will receive a single oral dose of Treatment 2: Formulation B followed by a washout period of at least 14 days from first dose of AZD4831. After the washout period, participants will receive a single oral dose of Treatment 1 Formulation A. | Drug: AZD4831<br>* Participants will receive a single oral dose of AZD4831 Formulation A Or a single oral dose of AZD4831 Formulation B on Day 1 Period 1. Depending on what Formulation was received on Day 1 Period 1, participants will receive either a single oral dose of AZD4831 Formulation A Or a single oral dose of AZD4831 Formulation B on Day 1 of Period 2.
