[Approval of clinical trials of immunobiological medicinal products at the Paul Ehrlich Institute]

[Regulatory framework of innovative therapies : From bench to bedside]

Novel therapies, e.g., cell and gene therapy or tissue engineering, are summarized in the European Union as advanced therapy medicinal products (ATMPs). In terms of composition and product properties, ATMPs are highly complex, and given their multiple potential actions they are subject to continuously developing regulatory requirements. Due to promising basic research findings, there are high expectations by the society toward the therapeutic potential of ATMPs. It is of utmost importance to develop a scientifically sound preclinical and clinical development plan before entering into the first clinical trial. Due to the complex features of ATMPs, this development plan should be discussed early with the regulatory authorities to define the specifics and challenges of each individual product. For planning as well as operational realization of the initial clinical trial involving ATMPs, specific requirements that need to be addressed are discussed in this paper.
