SEATTLE, May 12, 2021 (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, 2021. “During the first quarter of 2021, Chinook made strong progress with its pipeline of programs for kidney diseases, including initiating the phase 3 ALIGN and phase 2 AFFINITY trials of atrasentan, presenting encouraging clinical data from the BION-1301 program and entering into a strategic collaboration with Evotec,” said Eric Dobmeier, president and chief executive officer of Chinook Therapeutics. “We are well-capitalized and resourced to execute across our programs to generate additional data catalysts and continue building Chinook into a leading kidney disease company.” Recent Highlights Presented Gd-IgA1 biomarker data in healthy volunteers from Part 1 (single ascending dose) and Part 2 (multiple ascending dose) of the ongoing phase 1b study of BION-1301 at the ISN World Congress of Nephrology 2021, showing dose-dependent and durable reductions in Gd-IgA1 levels following administration of BION-1301.Presented data from the BION-1301 phase 1 intravenous to subcutaneous bioavailability study in healthy volunteers at the ISN World Congress of Nephrology 2021, demonstrating our ability to transition to subcutaneous administration of BION-1301 in cohort 2 of the ongoing phase 1b and future studies. Enrolled the first patient in the phase 2 AFFINITY basket trial of atrasentan, a highly potent and selective endothelin A receptor (ETA) antagonist (see www.clinicaltrials.gov, identifier NCT04573920). Chinook expects to report data from initial patient cohorts of this study in 2022. Enrolled the first patient with IgA nephropathy (IgAN) in the phase 3 ALIGN trial of atrasentan, (see www.clinicaltrials.gov, identifier NCT04573478). Chinook expects to report top-line proteinuria data from this study in 2023 to support potential accelerated approval from the FDA.Entered into a strategic collaboration with Evotec to discover and develop novel precision medicine therapies for lupus nephritis, IgAN, polycystic kidney disease (PKD) and other primary glomerular diseases by leveraging the National Unified Renal Translational Research Enterprise (NURTuRE) patient biobank and Evotec’s proprietary PanHunter multi-omics platform. Received rare pediatric disease designation from the U.S. Food and Drug Administration (FDA) for CHK-336, an investigational oral small molecule inhibitor of lactate dehydrogenase A (LDHA), for primary hyperoxaluria (PH). Anticipated Upcoming Catalysts Part 3 of Chinook’s phase 1b study of BION-1301 is currently enrolling IgAN patients in an open-label setting, and Chinook expects to present a small subset of interim patient data in an oral presentation at the 58th ERA-EDTA Congress in June, as well as additional patient data at the ASN Kidney Week 2021 in November. CHK-336 is currently in IND-enabling studies and advancing towards an expected IND submission in late 2021 or early 2022 for the treatment of primary hyperoxaluria. First Quarter 2021 Financial Results Cash Position – Cash, cash equivalents and marketable securities totaled $222.6 million at March 31, 2021, compared to $250.4 million at December 31, 2020. Revenue – Total revenue increased by $0.4 million for the first quarter of 2021 compared to the same period in 2020 due to revenue recognized related to research and development services provided under the collaboration agreement with Lilly, which was acquired under the merger with Aduro. Expenses – Research and development expenses were $25.7 million for the first quarter of 2021 compared to $2.8 million for the same period in 2020. The increase was primarily due to external clinical and manufacturing expenses related to the atrasentan and BION-1301 clinical programs; higher employee-related costs, including salaries, benefits and stock-based compensation expense associated with hiring staff to build out our clinical and development capabilities; increased spending for consulting and outside services; and higher facilities and other costs. The three months ended March 31, 2021 also includes an upfront fee of $3.3 million due to Evotech International GmbH under a research collaboration and license agreement entered into in February 2021.General and administrative expenses were $9.5 million for the first quarter of 2021 compared to $1.3 million for the same period in 2020. The increase was primarily due to higher employee-related costs, including salaries, benefits and stock-based compensation expense associated with the addition of administrative staff to buildout our public-company infrastructure; higher legal, consulting and outside services costs; and an increase in facilities and other costs.Expenses due to change in fair value of contingent consideration and amortization of intangibles were $2.3 million for the first quarter of 2021 compared to nil for the same period in 2020. These non-cash expenses are due to the quarterly revaluation of assets and liabilities related to the merger with Aduro. Net Loss – Net loss for the first quarter of 2021 was $37.2 million or $0.88 per share compared to net loss of $5.1 million or $1.25 per share for the same period in 2020. Cash Used in Operations – For the first quarter ended March 31, 2021, cash used in operations totaled $28.1 million. About Chinook Therapeutics, Inc.
