Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: Febuxostat XR 80 mg Capsule F1; Drug: Febuxostat XR 80 mg Capsule F2; Drug: Febuxostat XR 80 mg Capsule F3; Drug: Febuxostat XR 80 mg Capsule F4

• Registration Number: NCT02504320
• Lead Sponsor: Takeda

Brief Summary

This study will assess the relative bioavailability, safety and tolerability following administration of 80 mg single oral doses of 4 febuxostat extended release (XR) formulations.

Detailed Description

The drug being tested is this study is febuxostat XR. Four different formulations of febuxostat XR are being tested to see how the drug moves through the body. This study will look at safety and side effects in people who take febuxostat XR.

This cross-over study will enroll approximately 78 patients. Participants will be randomly assigned to 1of 4 sequences which will determine the order of the 4 treatments received:

* Febuxostat XR 80 mg capsule Formulation 1

* Febuxostat XR 80 mg capsule Formulation 2

* Febuxostat XR 80 mg capsule Formulation 3

* Febuxostat XR 80 mg capsule Formulation 4

Participants will take 1 dose on Day 1 with a washout period between each period.

This single-center trial will be conducted in the United States. The overall time to participate in this study is up to 80 days. Participants will make multiple visits to the clinic including a period of confinement, and will be contacted by telephone 30 days after last dose of study drug for a follow-up assessment.

Primary Outcome Measures

Name	Time	Method
Mean Cmax: Maximum Observed Plasma Concentration for Febuxostat	Day 1 pre-dose and at multiple time points (up to 48 hours) post-dose	Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.
Mean AUCt: Area Under the Plasma Concentration-Time Curve From Time 0 to the Time of the Last Quantifiable Concentration for Febuxostat	Day 1 pre-dose and at multiple time points (up to 48 hours) post-dose	AUCt is a measure of total plasma exposure to the drug from time 0 to time of the last quantifiable concentration.
Mean AUC∞: Area Under the Plasma Concentration-time Curve From Time 0 to Infinity for Febuxostat	Day 1 pre-dose and at multiple time points (up to 48 hours) post-dose	AUC∞ is a measure of total plasma exposure to the drug from time zero extrapolated to infinity.
