Brief summary

This Phase 1 study aims to quantify the effects of cyclosporine, a broad transporter inhibitor, and rifampicin, an OATP1B1/3 inhibitor, on verinurad pharmacokinetics (PK). The study is conducted in accordance with Food and Drug Administration guidance on Clinical Drug Interaction Studies, 2020. Verinurad will be developed as a fixed combination since it will always be administered together with allopurinol.

Detailed description

This Phase 1 study will be an open-label, 3-period, 3-treatment, fixed-sequence study in healthy subjects (males and females of non-childbearing potential), performed at a single Clinical Unit. The study will comprise of the following periods (visits): * A Screening Period (Visit 1); * A fixed sequence of 3 Treatment Periods during which subjects will be resident at the Clinical Unit from one day prior to administration of verinurad+allopurinol (Day -1) of Treatment Period 1 until the morning of Day 5 of the Treatment Period 2, and similarly for Treatment Period 3. There will be a washout period between Treatment Periods 2 and 3 dosing. The 3 Treatment Periods, include the washout period (Visits 2 to 3); * A Follow-up Visit, after the last administration of verinurad+allopurinol (Visit 4).

Interventions

The subjects will receive single oral dose of extended release capsule verinurad 7.5 mg on Day 1 of each treatment period under fasted condition.

DRUGAllopurinol

The subjects will receive single oral dose of tablet allopurinol 300 mg on Day 1 of each treatment period under fasted condition.

DRUGCyclosporine

The subjects will receive single oral dose of soft capsule cyclosporine 600 mg on Day 1 of treatment period 2 under fasted condition.

DRUGRifampicin

The subjects will receive single oral dose of film coated tablets rifampicin 600 mg on Day 1 of treatment period 3 under fasted condition.
