Reata Announces That Kyowa Hakko Kirin Initiated AYAME, a Phase 3 Trial of Bardoxolone Methyl for the Treatment of Diabetic Kidney Disease

IRVING, Texas, June 04, 2018 (GLOBE NEWSWIRE) -- Reata Pharmaceuticals, Inc. (Nasdaq:RETA), a clinical-stage biopharmaceutical company, today announced that its licensee, Kyowa Hakko Kirin Co., Ltd. (Kyowa Hakko Kirin), has initiated a Phase 3 clinical study, AYAME, to assess the efficacy and safety of bardoxolone methyl (bardoxolone) for the treatment of diabetic kidney disease in Japan.

In late 2017, Kyowa Hakko Kirin presented results from the Phase 2 TSUBAKI trial demonstrating that bardoxolone treatment led to statistically significant and clinically meaningful increases in directly-measured glomerular filtration rate (GFR) in patients with type 2 diabetes and chronic kidney disease (CKD) using the “gold standard” inulin clearance method.  By excluding patients at risk of fluid retention and monitoring patients carefully, bardoxolone was well tolerated.  There was no adverse effect on blood pressure and no evidence of overt fluid overload or cardiac toxicity.  Based on this and other data, Kyowa Hakko Kirin received SAKIGAKE Designation for bardoxolone for the treatment of diabetic kidney disease by the Japanese Ministry of Health, Labour and Welfare in March 2018.

AYAME is a multi-center, randomized, double-blind, placebo-controlled Phase 3 trial enrolling an estimated 700 diabetic kidney disease patients with CKD stage G3 or G4.  The primary efficacy endpoint is time to onset of a ≥ 30% decrease in estimated glomerular filtration rate (eGFR) from baseline or end-stage renal disease (ESRD).  Secondary endpoints include time to onset of a ≥ 40% or ≥ 53% decrease in eGFR from baseline or ESRD, time to onset of ESRD, and change from baseline in eGFR at each evaluation time point.  The estimated study completion date is March 2022.

In December 2009, Reata granted Kyowa Hakko Kirin the exclusive license to develop and commercialize bardoxolone in renal disease and certain other indications in Japan, China, Taiwan, South Korea, and Southeast Asia.  Kyowa Hakko Kirin is also currently collaborating with Reata in Japan on the ongoing Phase 3 CARDINAL study for bardoxolone in Alport syndrome, a severe, hereditary form of kidney disease.

About Bardoxolone

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 pulmonary arterial hypertension.  The European Commission has granted orphan designation in Europe to bardoxolone for the treatment of Alport syndrome.  In addition to AYAME, bardoxolone is currently being studied in CARDINAL, a Phase 3 study for the treatment of Alport syndrome, CATALYST, a Phase 3 study for the treatment of connective tissue disease associated pulmonary arterial hypertension, and PHOENIX, a Phase 2 study for the treatment of autosomal dominant polycystic kidney disease, IgA nephropathy, focal segmental glomerulosclerosis, and CKD associated with type 1 diabetes.
