SEATTLE, WA, USA I May 16, 2023 I Chinook Therapeutics, Inc. (Nasdaq: KDNY) today announced it has entered a collaboration agreement with Ionis Pharmaceuticals, Inc. for the discovery, development and commercialization of an antisense oligonucleotide (ASO) therapy for a rare, severe chronic kidney disease with significant unmet medical need. The companies will leverage Chinook’s precision medicine approach and deep expertise in nephrology and Ionis’ extensive expertise in RNA-targeted therapeutics.

“We are pleased to collaborate with Ionis on this preclinical discovery program as we continue to strengthen Chinook’s position as the leading kidney disease company,” said Andrew King, D.V.M, Ph.D., chief scientific officer of Chinook. “Developing an ASO therapy enhances our ability to target key genetic and molecular drivers and expands our precision medicine pipeline for rare severe chronic kidney diseases while continuing to pursue our goal of making dialysis and transplant unnecessary for people living with kidney disease.”

Under the terms of the agreement, Chinook will pay Ionis an undisclosed upfront payment as well as potential development and regulatory milestone payments and royalties. Ionis will be responsible for IND-enabling toxicology studies and Chinook will be responsible for clinical development and commercialization.

About Antisense Technology
Antisense therapies are designed to seek out, bind to and destroy a mRNA in a highly specific manner, so that the amount of disease-causing protein is dramatically decreased. Antisense therapies can also treat diseases caused by too little protein by increasing the production of the protein, thereby restoring the protein to normal levels.

About Chinook Therapeutics, Inc.
Chinook Therapeutics, Inc. is a clinical-stage biopharmaceutical 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, a phase 3 endothelin receptor antagonist for the treatment of IgA nephropathy and proteinuric glomerular diseases. BION-1301, an anti-APRIL monoclonal antibody, is being evaluated in a phase 1/2 trial for IgA nephropathy. CHK-336, an oral small molecule LDHA inhibitor for the treatment of hyperoxalurias, is in phase 1 development. In addition, Chinook’s research and discovery efforts are focused on building a pipeline of precision medicines for rare, severe chronic kidney diseases with defined genetic and molecular drivers. Chinook is leveraging insights from kidney single cell RNA sequencing and large CKD patient cohorts that have been comprehensively panomically phenotyped, with retained biosamples and prospective clinical follow-up, to discover and develop therapeutic candidates with mechanisms of action targeted against key kidney disease pathways.
