FDA approves test to monitor levels of Zortress in the bloodstream

SILVER SPRING, Md. —The Food and Drug Administration announced Friday the approval of Waltham, Mass.-based Thermo Fisher’s QMS Everolimus Immunoassay, a test that monitors the blood for levels of Novartis’ drug Zortress (everolimus).

Zortress is a drug used to prevent rejection of transplanted kidneys.

“QMS Everolimus is the first FDA-cleared test physicians can use to maintain appropriate levels of the immunosuppressant everolimus,” FDA Center for Devices and Radiological Health director Jeffrey Shuren said.
