Clinical investigation is the basis for establishing how useful advanced therapy investigational medicinal products (ATiMP) are for the treatment of serious diseases.In Spain, clinical trials (CT) on ATiMP need to follow the general European legislation on CT with medicinal products plus some specific legislation and guidance depending on the type of ATiMP.This chapter describes the characteristics of CT on ATiMP authorized in Spain in the period 2004-2022 and the legislation applicable along this period. There are clear differences in the clinical trials conducted by non commercial and commercial sponsors: the first have been more involved in CT on somatic cell therapy medicinal products (sCTMP) and tissue-engineered products (TEP), while the second drive more the CT on gene therapy medicinal products (GTMP) in the last years. Difficulties of budget and resources especially by non-commercial sponsors to meet the regulatory requirements are highlighted. The importance of complying with transparency rules with respect to CT on ATiMP is also discussed.
