Baxter International Inc., a global innovator in renal care, today announced the U.S. Food and Drug Administration (FDA) has granted the De Novo application for Theranova, the company’s novel dialysis membrane. Theranova was designed to deliver expanded hemodialysis (HDx) therapy, which filters a wider range of molecules from the blood than traditional hemodialysis (HD) filters, like high-flux membranes, by targeting effective removal of conventional (500 Da to 25 kDa) and large middle molecules (25 kDa to 45 kDa). These middle molecules may be associated with inflammation and cardiovascular disease in patients with kidney failure.
By granting a De Novo application, the FDA is establishing a new class of dialyzer technology with unique performance standards. The FDA utilizes the De Novo pathway for low and moderate risk medical devices that have no existing predicate in the United States; such designations are rare in the dialysis space. In fact, less than 1% of devices granted marketing authorization under De Novo have been for the care of patients with kidney failure since the pathway’s inception in 1997.
