Chinook Therapeutics, Inc. (NASDAQ: KDNY) is a clinical-stage biotechnology company developing precision medicines for kidney diseases. Chinook’s product candidates are being investigated in rare, severe chronic kidney disorders with opportunities for well-defined clinical pathways. Chinook’s lead program is atrasentan, an investigational phase 3 endothelin receptor antagonist for the treatment of IgA nephropathy and other proteinuric glomerular diseases. BION-1301, an investigational anti-APRIL monoclonal antibody is being evaluated in a phase 1b trial for IgA nephropathy. In addition, Chinook is advancing CHK-336, an investigational oral small molecule LDHA inhibitor for the treatment of primary hyperoxaluria, as well as research programs for other rare, severe chronic kidney diseases. Chinook is building its pipeline by leveraging insights in kidney single cell RNA sequencing, human-derived organoids and new translational models, to discover and develop therapeutics with differentiating mechanisms of action against key kidney disease pathways.
On March 30th Chinook announced upcoming data presentations at the ISN World Congress of Nephrology 2021 from April 15 – 19, 2021 and the 58th ERA-EDTA Congress from June 5 – 8, 2021.

KIDNEY DISEASE
Chronic kidney diseases are a severe and growing worldwide problem with a lack of effective treatments often leading to dialysis, transplantation, and high costs to health care systems. In the U.S. alone, kidney diseases affect an estimated 37 million people and account for over $120 billion in annual costs.
Drug development in kidney diseases is experiencing a resurgence due to greater understanding of disease biology, utilization of novel translational platforms and patient stratification tools, and emergence of accelerated regulatory pathways based on surrogate endpoints. These dynamics have converged to create attractive opportunities for the development of precision therapies.
One of the key challenges in studying and treating kidney disease has been the complexity of the organ, with nearly 30 distinct cell types, each with its own function and purpose. This cellular diversity and structure has made understanding the mechanisms associated with kidney function loss challenging. However, the recent development of single-cell RNA sequencing of different kidney cell populations presents a new opportunity to clearly understand the molecular mechanisms of kidney function and disease. Chinook utilizes single-cell RNA sequencing techniques and proprietary datasets developed by their academic founder, Ben Humphreys (Washington University, St. Louis, MO), to gain unprecedented insights into kidney disease mechanisms.
The cellular complexity of the kidney also presents barriers to developing translationally-relevant models of human kidney diseases. Recently, kidney organoids and patient-derived 3D kidney cellular systems have emerged as advanced preclinical models to study kidney disease. Chinook partners with leading academic collaborators to apply these novel human organoids as translational model systems for target validation in indications such as polycystic kidney disease. In addition, we’ve established patient-derived 3D cellular models of polycystic kidney disease in-house. We believe our approach using these and other validation tools provides significant insights into human disease mechanisms and allows us to select and validate key targets that are central drivers of human kidney diseases.
