Although the US Food and Drug Administration’s (FDA) generic drug approval process has a long-term successful track record, concerns remain for approval of narrow therapeutic index generic immunosuppressants, such as tacrolimus, in transplant recipients. Several professional transplant societies and publications have generated scepticism of the generics approval process. Three areas of concern are that the pharmacokinetic properties of generic and brand-name products in healthy volunteers may not reflect those in transplant recipients, bioequivalence between generic and brand-name products may not ensure bioequivalence between generics and high-risk patients may have specific bioequivalence concerns. While this study tests tacrolimus, the novel trial design and results may globally impact regulatory considerations and strategies, not only for the approval of immunosuppressants but also for other narrow therapeutic index/ critical dose drugs.
