SEATTLE, May 12, 2022 (GLOBE NEWSWIRE) -- Chinook Therapeutics, Inc. (NASDAQ:KDNY), a biopharmaceutical company focused on the discovery, development and commercialization of precision medicines for kidney diseases, today provided a business update and reported financial results for the first quarter ended March 31, 2022.

"During the first quarter of 2022, we made strong progress advancing our pipeline of clinical, research and discovery programs for rare, severe chronic kidney diseases. We continue to enroll patients in the phase 3 ALIGN and phase 2 AFFINITY trials for atrasentan as well as the phase 1/2 trial of BION-1301, and we are pleased to have recently initiated the phase 1 healthy volunteer trial of CHK-336, our first internally-discovered program for the treatment of primary and idiopathic hyperoxaluria," said Eric Dobmeier, president and chief executive officer of Chinook Therapeutics. "We look forward to the upcoming 59th ERA Congress being held May 19th – 22nd, where we will present clinical data from both our lead programs, atrasentan and BION-1301, in patients with IgA nephropathy (IgAN)."

Recent Accomplishments and Updates

Atrasentan

Atrasentan is a potent and selective endothelin A (ETA) receptor antagonist that has the potential to provide benefit in multiple chronic kidney diseases by reducing proteinuria and having direct anti-inflammatory and anti-fibrotic effects to preserve kidney function. The phase 3 ALIGN trial of atrasentan is currently enrolling patients with IgAN, and the phase 2 AFFINITY basket trial of atrasentan is currently enrolling patients with proteinuric glomerular diseases.

BION-1301

BION-1301 is a novel anti-APRIL monoclonal antibody currently in phase 1/2 development for patients with IgAN. BION-1301's potentially disease-modifying approach to treating IgAN by reducing circulating levels of galactose-deficient IgA1 (Gd-IgA1) to prevent the formation of pathogenic immune complexes has been demonstrated preclinically as well as clinically in both healthy volunteers and patients with IgAN.

CHK-336

CHK-336 is an oral small molecule lactate dehydrogenase A (LDHA) inhibitor with liver-targeted tissue distribution that Chinook is developing for the treatment of patients with primary hyperoxaluria (PH), secondary hyperoxaluria due to increased endogenous oxalate production and idiopathic stone formation.

Precision Medicine Research & Discovery

Chinook is focused on the discovery and development of novel precision medicines for rare, severe chronic kidney diseases (CKDs) with defined genetic or molecular drivers of disease initiation and progression, and efficient development paths. Chinook has multiple preclinical programs across the discovery, target validation, lead identification and lead optimization stages to generate future clinical pipeline candidates. Chinook is leveraging its ongoing strategic collaboration with Evotec to identify and validate novel targets and enable patient stratification strategies through access to the NURTuRE CKD Patient Biobank, which provides comprehensive PANOMICS characterization of thousands of CKD patients with prospective clinical follow-up and retained bio-samples of urine and blood for exploratory biomarker analysis.
