FDA approves Voraxaze to treat patients with toxic methotrexate levels
The U.S. Food and Drug Administration recently approved Voraxaze (glucarpidase) to treat patients with toxic levels of methotrexate in their blood due to kidney failure.
Methotrexate is a commonly used cancer chemotherapy drug normally eliminated from the body by the kidneys. However, patients receiving high doses of methotrexate may develop kidney failure.
Voraxaze is an enzyme that rapidly reduces methotrexate levels by breaking the chemotherapy drug down to a form that can be eliminated from the body. Voraxaze is administered directly into a patient’s vein (intravenously).
Voraxaze has an orphan drug designation, given to therapies indicated for rare or specific disease populations.
The most common side effects observed in greater than one percent of patients in the clinical study were low blood pressure (hypotension), headache, nausea, vomiting, flushing, and abnormal sensation (paraesthesia).
