|Reata Provides Update on the Phase 2 Portion of the CARDINAL Study of Bardoxolone Methyl in Patients With Alport Syndrome|
Bardoxolone Treatment Produced Significant Increase in Kidney Function Maintained Through Week 36
Conference Call With Management Scheduled
Efficacy results demonstrate that significant increases in kidney function, as measured by estimated glomerular filtration rate (eGFR), are maintained through Week 36. The mean improvement from baseline in eGFR at Week 36 is 11.3 mL/min/1.73 m2 (n=27; p<0.0000001), which is not significantly different than the change observed at Week 12. Initial increases in urinary albumin to creatinine ratio that were due to increases in eGFR have stabilized. Adverse events have been generally mild to moderate in severity, and no drug-related serious adverse events have been reported.
“Bardoxolone continues to be well-tolerated in Alport syndrome patients as evidenced by the encouraging safety profile and high patient retention rate in the Phase 2 cohort of CARDINAL,” said
Reata management will host a call to discuss these results on
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 and is designed to demonstrate that bardoxolone has disease-modifying activity in Alport syndrome patients. Based upon guidance from the
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 – 60,000 people 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.
