Advanced therapy products, considered special medications, require Anvisa approval for use and commercialization in Brazil. They include advanced cellular therapy products, tissue engineering products, and gene therapy products, which due to their complexity involve innovation and risks, optimized regulatory channels for their development and life cycle monitoring. The scientific elements and the compliance with applicable regulatory aspects are fundamental pillars for the advancement of clinical trials, the positive evidence of the benefit-risk profile, and the definition of the critical quality attributes, from the perspective of making safe, efficacy, and high-quality products available to the population. The approval models of these products in Brazil adapt to the specificities and characteristics of the technology and the patient target population, with accelerated regulatory analyses, use in emergency situations by risk controls and specific monitoring mechanisms, principally those related to rare diseases without other therapeutic alternatives. The opportune access to the advance therapy product with safety, efficacy, and quality involves innovative normative elements that include the long-term follow-up of the safety and efficacy and of the adaptive pharmacovigilance requisites, as well as the traceability mechanisms for starting materials, products, and patients.
