Our Science

We explore the frontiers of science to further human health.

Our Technologies

Reata has active clinical, preclinical, and internal discovery programs in many significant disease areas. We focus on molecular pathways that regulate cellular metabolism, inflammation, and the response to cellular stress in serious and life-threatening diseases that have limited or no approved therapies.

Nrf2 Activators

Kelch domain of Keap1
PDB Code 2FLU

Nrf2 is a transcription factor that promotes the resolution of inflammation by restoring mitochondrial function, reducing oxidative stress, and inhibiting pro-inflammatory signaling (1-4). Omaveloxolone and Bardoxolone methyl are in development for the treatment of a severe neurological disorder called Friedreich’s ataxia and several forms of chronic kidney disease, respectively.

HSP90 Modulators

We are developing a novel class of molecules that target pathways involved in the cellular stress response. Our lead product candidate, RTA 901, and related analogs have shown promising effects in animal models of neurological disease. RTA 901 is in development for Diabetic Peripheral Neuropathic Pain.

Our Pipeline

Reata’s development programs have created a robust pipeline of drug candidates for the treatment of serious, life-threatening diseases.

The Phase 2 MOXIe Part 2 study was an international, multi-center, double-blind, placebo-controlled, randomized registrational study, that enrolled 103 patients with Friedreich’s ataxia (FA) at 11 study sites in the United States, Europe, and Australia and is the largest global, interventional study ever conducted in FA. Patients were randomized 1:1 to 150 mg of omaveloxolone or placebo. The primary endpoint was change in the modified Friedreich’s Ataxia Rating Scale (mFARS) relative to placebo after 48 weeks of treatment.

RTA 901

We completed a Phase 1 SAD/MAD trial of oral, once-daily RTA 901 in healthy adult volunteers to evaluate the safety, tolerability, and PK profile. No safety or tolerability concerns were reported, and we observed an acceptable PK profile.

The Phase 3 CARDINAL study was an international, multi-center, double-blind, placebo-controlled, randomized clinical trial that enrolled 157 patients with CKD caused by Alport syndrome at approximately 50 study sites in the United States, Europe, Japan, and Australia. Patients were randomized 1:1 to bardoxolone or placebo. The primary endpoint for Year 2 of the study was the change from baseline in eGFR after 100 weeks of treatment (end-of-treatment). The key secondary endpoint for Year 2 of the study was the change from baseline in eGFR at Week 104 (four weeks after last dose in second year of treatment).

AYAME is a randomized, double-blind, placebo-controlled, registrational outcomes trial of bardoxolone methyl in patients with diabetic CKD in Japan. The study enrolled approximately 1,000 Stage 3 and 4 diabetic kidney disease patients. The primary endpoint is the time to onset of at least a 30% decline in eGFR or end-stage kidney disease. AYAME is conducted by our strategic collaborator in Japan, Kyowa Kirin Co., Ltd.

On February 25, 2022, we received a Complete Response Letter from the Food and Drug Administration (FDA). We will continue to work with the FDA to confirm our next steps on our Alport syndrome program.

Omaveloxolone, bardoxolone methyl, and RTA 901 are investigational drugs. Safety and efficacy have not been established by any agency.
