Objective This article critically evaluates the European Commission’s 2024 Implementing Regulation (IR) on conflicts of interest (COIs) management for stakeholders in the European Union (EU) Joint Clinical Assessment (JCA), with a focus on individual experts such as clinicians and patient representatives.

Key findings The IR is the first EU-level framework to assess COIs in the context of health technology assessment (HTA). The regulation requires experts involved in the JCA to submit annual declarations of interest for both financial and non-financial interests and presents a matrix on whether these conflicts should disqualify them from participating in the joint work. We compared the IR to COIs-management approaches from other European national HTA bodies and found that the IR is closely modelled after the French guidelines. Concerns include potential over-representation of experts from a small number of countries, lack of guidance on organisational COIs, and ambiguities in how the size of financial interests are disclosed. Unclear resource allocation for enforcement could also hinder compliance.

Conclusions The IR marks progress in EU-wide HTA collaboration, but improvements in transparency, expert diversity, and comprehensive COIs management are needed to ensure impartiality in the JCA process.
