Payer and Implementation Challenges with Advanced Therapy Medicinal Products (ATMPs).

Advanced therapy medicinal products (ATMPs) are a dynamic and current topic for healthcare systems, with new products progressing to market at an increasing rate. ATMPs highlight the growing gap between payer and regulator requirements; the limited evidence base combined with pressure to implement rapidly is exacerbating the clinical and financial uncertainties associated with these products. There are a number of key uncertainties with ATMPs related to implementation and healthcare planning-these uncertainties at the time of evaluation have the ability to change the value proposition of products.
