Abstract
Complex drugs may be either biological, if the active ingredients are derived from a biological source, or non-biological, if obtained by chemical synthesis. In both cases, their quality depends considerably on the manufacturing process. In the case of Non Biological Complex Drugs (NBCDs), complexity may arise either from the active substance, as in the case of glatiramer acetate, or from other sources, such as the formulation, as in the case of liposomes. In this paper, the case of glatiramer acetate (GA) - a NBCD relevant for clinical and economic reasons - is considered and the differences between US and EU regulatory approaches to GA marketing authorization are highlighted. Indeed, though US and EU regulatory agencies have chosen a generic approach integrated with additional data the implementation is different in the two jurisdictions. In the US, the additional data required are listed in a product specific guideline and copies of Copaxone® have been approved as generics. In the EU, instead regulatory agencies followed a hybrid approach requiring an additional comparative study, and interchangeability policies and substitution schemes have been left to national agencies.File | Dimensione | Formato | |
