A Pharmacokinetic Study of Omaveloxolone in Healthy Volunteers

Study Overview
=================
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
-----------------
This study was previously posted by Reata Pharmaceuticals. In September 2023, sponsorship of the trial was transferred to Biogen.

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Food Effect (Fasted)<br>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. | Drug: omaveloxolone<br>* Omaveloxolone 50 mg capsules<br>* Other names: RTA 408;|
| Experimental: Effect (Fed)<br>Subjects will be randomly assigned to one of the two treatment sequences.

| Experimental: Dose Proportionality<br>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. | Drug: omaveloxolone<br>* Omaveloxolone 50 mg capsules<br>* Other names: RTA 408;|

What is the study measuring?
-----------------
Primary Outcome Measures

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

Secondary Outcome Measures

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