bardoxolone methyl improveD kidney function in patients with autosomal dominant polycystic kidney disease and iga nephropathy in the ongoing phase 2 phoenix Study
interim data DEMONSTRATE significant improvement in kidney function in both diseases
Conference Call with management scheduled today, May 25, 2018 at 8:00am ET
IRVING, Texas, May 25, 2018 – Reata Pharmaceuticals, Inc. (NASDAQ:RETA), a clinical-stage biopharmaceutical company, today announced that positive interim data from the autosomal dominant polycystic kidney disease (ADPKD) and IgA nephropathy cohorts of the ongoing, open-label, Phase 2 PHOENIX trial are being presented by Pablo E. Pergola, M.D., Ph.D., Research Director, Renal Associates, PA, San Antonio, at the European Renal Association and European Dialysis and Transplant Association (ERA-EDTA) meeting in Copenhagen.
The ADPKD cohort of PHOENIX enrolled 31 patients, and available data demonstrate that bardoxolone methyl (bardoxolone) significantly improved kidney function in ADPKD patients as measured by their estimated glomerular filtration rate (eGFR). Bardoxolone-treated patients showed a mean improvement of 6.6 mL/min/1.73 m2 at Week 4 (n=31; p<0.0001), increasing to 12.0 mL/min/1.73 m2 at Week 12 (n=8; p<0.0001) from a mean baseline eGFR of 47.7 mL/min/1.73 m2. The IgA nephropathy cohort enrolled 26 patients, and data were reported through Week 8. Bardoxolone-treated patients showed a mean improvement of 8.4 mL/min/1.73 m2 at Week 8 (n=9; p<0.0001) from a mean baseline eGFR of 46.2 mL/min/1.73 m2. No drug-related serious adverse events have been reported, and reported adverse events have generally been mild to moderate in intensity. Full data for the primary endpoint of change in eGFR at Week 12 for the ADPKD, IgA nephropathy, and type 1 diabetic chronic kidney disease (CKD) cohorts of PHOENIX will be available in the third quarter of 2018.
“Bardoxolone has now produced large improvements in kidney function in a high percentage of patients spanning 11 trials and five different forms of chronic kidney disease,” said Dr. Pergola. “These observations suggest that bardoxolone is addressing pathogenic pathways of inflammation and fibrosis that contribute to the loss of kidney function in patients with chronic kidney disease.”
Additionally, Dr. Christoph Wanner, M.D., Chief of the Division of Nephrology and Hypertension at the University Hospital of Würzburg, Germany, gave an oral presentation at ERA-EDTA entitled “Bardoxolone Methyl Prevents eGFR Decline in Patients with Chronic Kidney Disease Stage 4 and Type 2 Diabetes ─ Post-hoc Analyses from BEACON.” The analysis demonstrated that patients randomized to bardoxolone were more than 50 percent less likely than patients receiving placebo to experience events that predict kidney failure. The authors of the abstract concluded that bardoxolone preserves kidney function and may delay the onset of kidney failure in patients with type 2 diabetes and stage 4 CKD. The abstract was named a Ten Best Abstract by the Paper Selection Committee of ERA-EDTA.
“Bardoxolone’s improvements in kidney function in patients with ADPKD and IgA nephropathy are consistent with improvements observed in other forms of CKD, which have been durable and predictive of retained eGFR benefit after

withdrawal of drug in prior trials,” said Colin Meyer, M.D., Reata’s Chief Medical Officer. “Additionally, selection of the BEACON outcomes analysis for oral presentation at one the world’s top nephrology meetings, six years after BEACON concluded, reinforces the importance of the study’s results. The durable increases in eGFR associated with a 50 percent reduction in outcomes inspire optimism for bardoxolone’s potential to delay or prevent dialysis in CKD.”
Reata management will host a call at 8:00 a.m. ET today to review these data and the development program for bardoxolone in chronic kidney disease.

About Autosomal Dominant Polycystic Kidney Disease
ADPKD is a genetic form of CKD caused by mutations in PKD1 and PKD2 genes leading to inflammation that stimulates the formation of fluid-filled cysts in the kidneys that cause pain and progressive loss of kidney function. ADPKD is the leading inheritable cause of kidney failure with an estimated 116,000 diagnosed patients in the United States.
About IgA Nephropathy
IgA nephropathy, also known as Berger’s Disease, is a rare form of CKD that is characterized by deposits of IgA immune complexes in the glomeruli leading to persistent inflammation, oxidative stress, and loss of kidney function. IgA nephropathy is one of the most prevalent primary chronic glomerular diseases with an estimated 120,000 patients in the United States. There are currently no FDA-approved therapies for IgA nephropathy.
About the PHOENIX Study
The Phase 2 PHOENIX program is studying bardoxolone in patients with ADPKD, IgA nephropathy, focal segmental glomerulosclerosis, and CKD associated with type 1 diabetes. Patients receive bardoxolone open-label, orally, once-daily for 12 weeks, and the primary efficacy endpoint is change from baseline in eGFR after 12 weeks of treatment. Endpoints will be assessed for each cohort separately.
About Bardoxolone Methyl
Bardoxolone is an experimental, oral, once-daily activator of Nrf2, a transcription factor that induces molecular pathways that promote the resolution of inflammation by restoring mitochondrial function, reducing oxidative stress, and inhibiting pro-inflammatory signaling. The FDA has granted orphan designation to bardoxolone for the treatment of Alport syndrome and for the treatment of connective tissue disease associated pulmonary arterial hypertension.

About Reata Pharmaceuticals, Inc.
Reata is a clinical-stage biopharmaceutical company that develops novel therapeutics for patients with serious or life-threatening diseases by targeting molecular pathways involved in the regulation of cellular metabolism and inflammation. Reata’s two most advanced clinical candidates, bardoxolone methyl and omaveloxolone, target the important transcription factor Nrf2 that promotes the resolution of inflammation by restoring mitochondrial function, reducing oxidative stress, and inhibiting pro-inflammatory signaling.
