Statistically Significant Improvement in Kidney Function Maintained in Alport Syndrome Patients After 48 Weeks of Treatment
Statistically Significant Retained Benefit of 4.1 mL/min in Alport Syndrome Patients Following 48 Weeks of Treatment and 4 Weeks of Drug Withdrawal
Statistically Significant Improvement in Kidney Function Observed in ADPKD Patients After 12 Weeks of Treatment
Conference Call With Management Scheduled for Today
In the Phase 2 portion of CARDINAL, significantly increased estimated glomerular filtration rate (eGFR) at Week 48 from baseline (n=25) of 10.4 mL/min/1.73 m2 (p<0.0001) was observed in patients treated with bardoxolone. Reata collected historical eGFR data for 22 out of the 25 Phase 2 study subjects. The historical eGFR data demonstrate that the Phase 2 study subjects’ kidney function was declining at an average annual rate of 4.2 mL/min/1.73 m2 prior to study entry. The observed 10.4 mL/min/1.73 m2 improvement after one year of treatment with bardoxolone represents a recovery of approximately two years of average eGFR loss.
Significantly increased eGFR from baseline at Week 52 after withdrawal of active drug for four weeks (the retained eGFR benefit) by a mean of 4.1 mL/min/1.73 m2 (p<0.05) was also observed with bardoxolone treated patients. These results provide evidence that bardoxolone may delay or prevent kidney failure.
With respect to safety in the Phase 2 portion of CARDINAL, no treatment-related serious adverse events have been reported, and the reported adverse events have generally been mild to moderate in intensity. Twenty-five patients were available for the analysis, and no discontinuations were due to bardoxolone treatment.
In the Phase 2 ADPKD cohort of

About the Retained eGFR Benefit Analysis
About the CARDINAL Clinical Study
CARDINAL is an international, multi-center, Phase 2/3 study enrolling patients from 12 to 60 years old with a confirmed genetic or histological diagnosis of Alport syndrome, baseline eGFR values between 30 to 90 mL/min/1.73 m2, and on stable renin-angiotensin-aldosterone system blockade unless contraindicated. The Phase 2 portion of CARDINAL is open-label and enrolled 30 patients. The Phase 3 portion of CARDINAL is double-blind, placebo-controlled, and will randomize approximately 150 patients on a 1:1 basis to once-daily, oral bardoxolone or placebo.
The Phase 3 primary efficacy endpoint is the on-treatment eGFR change from baseline in bardoxolone-treated patients relative to placebo at Week 48. The key secondary endpoint of the Phase 3 portion of the trial is the change from baseline in retained eGFR benefit after 48 weeks on-treatment and four weeks off-treatment relative to placebo and is designed to demonstrate that bardoxolone has disease-modifying activity in Alport syndrome patients. Based upon guidance from the
About the PHOENIX Clinical 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 Alport Syndrome
Alport syndrome is a rare, genetic form of CKD caused by mutations in the genes encoding type IV collagen, which is a major structural component of the glomerular basement membrane (GBM) in the kidney. The abnormal expression of type IV collagen causes loss of GBM integrity, abnormal leakage of proteins through the GBM, and excessive reabsorption of protein in the proximal tubules of the kidney. Like other forms of CKD, excessive reabsorption of protein in the tubules induces oxidative stress, chronic inflammation, and renal interstitial inflammation and fibrosis.
Alport syndrome affects approximately 30,000 to 60,000 people in
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 400,000 patients in
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
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 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.
