Regulatory Considerations for Clinical Trial Applications with CRISPR-Based Medicinal Products.

Since first proposed as a new tool for gene targeting and genome editing, CRISPR technology has quickly advanced into the clinical stage. Initial studies highlight the potential for CRISPR-Cas9-mediated therapeutic approaches in human medicine to correct incurable genetic diseases and enhance cell-based therapeutic approaches. While acknowledging the opportunities this technology brings for the treatment of patients with severe diseases, timely development of these innovative medicinal products requires regulatory oversight and adaptation of regulatory requirements to ensure the safety and efficacy of medicinal products based on CRISPR technology. We briefly present the current regulatory framework applicable for CRISPR-Cas-based developments as advanced therapy medicinal products. Moreover, scientific- and regulatory-driven considerations relevant for advancing product development toward clinical trial applications in Germany are highlighted by discussing the key aspects of quality and nonclinical and clinical development requirements.
