A Pharmacokinetic Study of Omaveloxolone in Healthy Volunteers

Phase 1

Completed

• Conditions: Healthy
• Interventions: Drug: omaveloxolone

• Registration Number: NCT03664453
• Lead Sponsor: Reata, a wholly owned subsidiary of Biogen

Brief Summary

This study will determine the effect of food on the pharmacokinetics of omaveloxolone (150 mg) in healthy adult subjects and will assess the safety, tolerability, and dose proportionality of 50 mg, 100 mg, and 150 mg omaveloxolone in healthy adult subjects.

The study will be conducted in two parts, conducted simultaneously. Part 1 will assess the food effect, while Part 2 will assess dose proportionality.

Detailed Description

Study Sponsor, originally Reata Pharmaceuticals, Inc., is now Reata Pharmaceuticals, Inc., a wholly owned subsidiary of Biogen.

Arm && Interventions

Group	Intervention	Description
Effect (Fed)	omaveloxolone	Subjects will be randomly assigned to one of the two treatment sequences. Two single doses of omaveloxolone 150 mg (taken in multiple 50 mg capsules) will be administered to the subjects beginning in the fed state (Period 1) with a crossover and then in the fasted state (Period 2). Subjects will be confined beginning on Study Day -1 through the last PK blood draw on Study Day 6 during Period 1, and from Study Day 14 through the last PK blood draw on Study Day 20 during Period 2.
Dose Proportionality	omaveloxolone	Subjects will be randomly assigned to one of two omaveloxolone dosages. A single dose of omaveloxolone (in either 50 mg or 100 mg) will be administered to the subjects in 50 mg capsules in a fasted state. Subjects will be confined beginning on Study Day -1 through the last blood sample collection on Study Day 6.
Food Effect (Fasted)	omaveloxolone	Subjects will be randomly assigned to one of the two treatment sequences. Two single doses of omaveloxolone 150 mg (taken in multiple 50 mg capsules) will be administered to the subjects beginning in the fasted state (Period 1) with a crossover and then in the fed state (Period 2). Subjects will be confined beginning on Study Day -1 through the last PK blood draw on Study Day 6 during Period 1, and from Study Day 14 through the last PK blood draw on Study Day 20 during Period 2.

Primary Outcome Measures

Name	Time	Method
Determine the effect of food on the pharmacokinetics of omaveloxolone in healthy adult subjects by measuring area under curve (AUC)	20 days	Pharmacokinetics will be assessed by blood sampling for omaveloxolone to determine area under curve (AUC).
Determine the effect of food on the pharmacokinetics of omaveloxolone in healthy adult subjects by measuring maximum observed concentration (Cmax)	20 days	Pharmacokinetics will be assessed by blood sampling for omaveloxolone to determine maximum observed concentration (Cmax).

Secondary Outcome Measures

Name	Time	Method
Incidence of treatment-emergent adverse events	6 days	Safety will be assessed based on the number of treatment-emergent adverse events as defined by the Medical Dictionary for Regulatory Activities (MedDRA)
