Study to Assess the Safety, Tolerability, and Pharmacodynamics of RTA 402 in Patients With Hepatic Dysfunction

Detailed Description
RTA 402 is a synthetic triterpenoid that is designed to suppress oxidative stress and inflammatory processes that play a significant role in a wide variety of diseases. It is a potent suppressor of inflammation and oxidative stress. Oxidative stress plays a role in the pathogenesis of hepatitis, and RTA 402 has demonstrated activity in a preclinical model of hepatitis, in addition to other models of inflammation.
This is a 28-day, multiple-dose, dose-escalation study. It is anticipated that a total of 3 groups of 8 patients each will be enrolled, in which 6 patients in each group will be randomized to receive RTA 402, and 2 patients per group will be randomized to placebo (3:1). Patients will receive treatment daily for 14 days with a starting dose of 5mg, 25mg, or 50mg. Patients will return for follow up visits on Days 16 and 21, and complete end of study procedures on Day 28.
Study Sponsor, originally Reata Pharmaceuticals, Inc., is now Reata Pharmaceuticals, Inc., a wholly owned subsidiary of Biogen.
