Facilitates Ordering of Test for AKI Risk Assessment; Increases Convenience and Confidence for Customers

SAN DIEGO – June 9, 2016 – Astute Medical, Inc., developer of biomarkers for better healthcare, today announced that it has received U.S. Food and Drug Administration (FDA) 510(k) clearance for improvements to the NephroCheck® Test Kit U.S that will extend the shelf life for the test to 12 months when refrigerated.

The NephroCheck® Test is a first-of-a-kind laboratory test to help determine if certain hospitalized patients are at risk of developing moderate to severe acute kidney injury (AKI) in the 12 hours following test administration. Early knowledge that a patient is likely to develop AKI may prompt closer patient surveillance and help prevent permanent kidney damage or death.

“Improved shelf life enables hospital labs to better optimize their inventory and ordering process providing multiple advantages for customers,” said Ryan Roberts, Astute chief commercial officer. “Labs will be able to maintain larger inventories to support test demand from critical care units and also place larger orders, which may help them qualify for our volume purchasing agreements.”

Astute expects to make the product with extended shelf life available to customers later this year. The contents and formulations of the test kit have not changed.

Hospital-acquired AKI has been shown to strike in up to 18 percent of hospital patients1 and up to 50 percent of intensive care unit patients.2 It often arises as a complication of common events, including infection, surgery or trauma,3 and requires timely intervention in order to prevent irreversible kidney damage.1 By one estimate, the healthcare cost burden for AKI is as high as $10 billion in the United States alone,4 driven by cost of care, longer hospital stays5 and readmissions.6 AKI has also been linked to exponential increases in hospital mortality rates7 and premature death.8
