The European Network for Health Technology Assessment (EUnetHTA) has led together, with member states, several joint actions, including Joint Clinical Assessments (JCA), under the form of project-based voluntary cooperation, which outputs and transferability of those projects in other European countries remains somehow limited. In June 2021, the European Council has reached an agreement on the European Health Technology Assessment (HTA) regulation, which is entering into force gradually. Initially limited to oncology products, then extended to orphan/advanced therapy, and after a five to eight-year additional period, it will apply to all centrally approved products. The JCA will consist of a focused scientific analysis on relative effectiveness assessment, including the health condition, technology description, clinical effectiveness, and safety. These analyses will also include information relating to the degree of certainty. We consider that the evidence appraisal might have limitations, and transferability would not be generalizable. We aim to determine the potential drivers and barriers for HTA transferability in EU4, employing the analysis of a case example where JCA was conducted.

Employing an oncology JCA, we will compare an HTA analysis conducted in EU4 countries (Germany, France, Italy, and Spain). Overview and background information on countries involved in the JCA, and EU4 HTA system will be provided, followed by HTA outcome and main evidence requirements, reimbursement outcome, and pricing agreements.

Study results supporting HTA outcomes may focus on the population assessed, the comparator considered, and uncertainty management. A conceptual adaptation about the scope of the EU JCA regulation will be discussed, to understand its potential advantages to individual HTAs in Europe and remaining gaps to effectively inform HTA or decision-making process.

The analysis of pricing and reimbursement outcomes can further help understand potential barriers and drivers for JCA transferability and potential areas of evidence generation requirements.
