Novartis agreed to acquire clinical-stage biopharmaceutical company Chinook Therapeutics for up to $3.5 billion, in a deal that will expand its portfolio of kidney disease treatments.

The Swiss pharmaceutical company said Monday that it would merge Seattle, Washington-based Chinook Therapeutics with a newly formed Novartis subsidiary, with holders of Chinook common stock receiving $3.2 billion in cash, plus a contingent value right of up to $300 million.

The deal will hand Novartis exposure to Chinook's pipeline for kidney disease treatments. These include atrasentan and zigakibart to treat Immunoglobulin A Nephropathy, a rare kidney disease that affects mostly young adults, with as many as three in 10 patients progressing to kidney failure and dialysis within 10 years.

Atrasentan is currently in Phase 3 development, while a Phase 3 trial for zigakibart is expected to start in the third quarter.

Novartis expects to close the transaction in the second half of the year, subject to customary closing conditions.
