Pull Mycophenolate Mofetil Draft Guidance: Petition
A petition submitted by the Haynes and Boone law firm asks FDA not to approve any ANDA for a mycophenolate mofetil oral suspension product that relies on only metabolite data to establish bioequivalence to the reference-listed drug (Roche’s CellCept). The firm’s 3/6 petition also asks the agency to change the therapeutic equivalence rating from AB for any previously approved ANDA for a mycophenolate mofetil oral suspension product that relies only on metabolite data to establish bioequivalence to the reference-listed drug (RLD) or that does not include a nasogastric study as required by the current draft guidance.
The petition says that FDA should withdraw its draft guidance on the product and then issue new guidance requiring use of data for both the parent compound and its metabolite to establish bioequivalence with the RLD.
