Guidance on Cyclosporine Bioequivalence Posted
FDA has released a draft guidance on Cyclosporine Bioequivalence Recommendations for generic cyclosporine 0.05% emulsion/ophthalmic products. The document offers two options — an in vitro or in vivo study for demonstrating bioequivalence. The agency says that in order to qualify for the in vitro option, the test and reference-listed drug (RLD) formulations should be qualitatively and quantitatively the same. Also, the comparative study should be performed on at least three exhibit lots of both test and RLD products.
