Market access challenges in the EU for high medical value diagnostic tests.

The clinical utility and medico-economic value of several personalized diagnostic tests has been well described in the literature. Development of such tests, including generation of the necessary supportive clinical validation data, is a complex and expensive endeavor. In general, sponsors of such tests lack sufficient clarity on appropriate reimbursement and regulatory pathways to provide the clear development framework necessary to incentivize the required level of investment. In the USA, an imperfect reimbursement paradigm has evolved to accommodate a small number of 'value-priced' laboratory-developed tests, although major structural barriers remain to broader implementation. In Europe, by contrast, there is virtually no precedent for value-based public sector pricing, and even such procedurally based pricing as currently exists is administered by a complex network of largely decentralized bodies. As a consequence, patient access is limited and health-economic savings are not realized. This article explores some of the European market entry barriers, with a focus on reimbursement challenges, and highlights some collaborative proposals to address such.
