Understanding the role and evidence expectations of health technology assessment and coverage/payer bodies: What are they looking for, and how and why does this differ from what regulators require?

Pharmaceutical companies have a good understanding of the needs and requirements of regulatory bodies, but the evidence expectations of health technology assessment (HTA) and coverage/payer bodies are less well understood and addressed. This paper seeks to improve this understanding by providing an overview of the expectations of HTA and coverage/payer bodies, explaining how and why these differ from those of regulators, and describing the extent and limitations of work on harmonization. The article goes on to describe ways in which HTA and coverage/payer bodies' expectations can be addressed, and to encourage industry to interact with HTA and coverage/payer bodies to increase mutual understanding and hence promote more efficient development of and access to innovative medicines.
