Vifor Asks FDA Reconsideration of Some Venofer Actions

Share

 

Vifor has petitioned FDA for reconsideration and a stay of certain actions the agency has taken with respect to Venofer (iron sucrose USP) injection that the company says will undermine the public health and are contrary to law. The 6/25 petition arises from FDA’s 5/26 response to an earlier Vifor petition.

Vifor says it does not challenge the response’s conclusion that the solid oral tablet Velphoro (sucroferric oxyhydroxide) was not entitled to new chemical entity exclusivity. But it does challenge the portions of the response that purport to change the established names and active ingredients of Velphoro and several IV iron products, including Venofer, to “ferric oxyhydroxide.” The petition also challenges the actions the agency has taken to implement the change in the Orange Book and in Drugs@FDA.

“We respectfully request that FDA reconsider its decision to change the established name and redefine the active ingredients of iron-containing complex drugs,” Vifor says. “FDA should maintain the distinct established names and active ingredients of these products, many of which have been settled for decades.”
