On 12 December 2014, the US Food and Drug Administration (FDA) released 31 new draft guidance documents and 22 revisions to guidance documents on bioequivalence requirements for the development of generics containing 42 different active ingredients.
The new draft bioequivalence guidance documents cover generics of acne treatment Aczone (dapsone), antipsychotic medication Latuda, (lurasidone), chemotherapy drug Stivarga (regorafenib), HIV medicine Stribild (cobicistat/elvitegravir/emtricitabine/tenofovir), head lice treatment Ulesfia (benzyl alcohol) and arthritis treatment Xeljanz (tofacitinib), among others, see Table 1.
Revised bioequivalence guidance documents include those for generics of high blood pressure treatment Bystolic (nebivolol), chemotherapy drug Doxil (doxorubicin), acne treatment Epiduo (adapalene/benzoyl peroxide) and Alzheimer’s drug Namenda (memantine), to name just a few, see Table 2.

The draft guidance documents recommend whatin vivoandin vitrostudies generics companies should carry out in order to demonstrate bioequivalence. The number of studies, the population to be studied, blood sampling time points and analytes to be measured in blood samples are also detailed in the draft guidance documents.
In total, FDA now has 1,236 product-specific guidelines with bioequivalence study recommendations. The agency also has an overarching guidance document on bioequivalence recommendations for specific products [1].
Comments on the draft guidance documents can be posted to the Division of Dockets Management (DDM) under Docket FDA-2007-D-0369-0015. This can be done via the website www.regulations.gov or written comments can be mailed to DDM (HFA-305), FDA, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
