Decentralized clinical trials for medications to reduce the risk of dementia: Consensus report and guidance

Howard et al.

The finding, in our words

A modified Delphi consensus panel developed 40 pragmatic recommendations to guide the delivery of decentralised clinical trials for dementia risk-reduction medications. The guidance outlines necessary safety balances, dispensing protocols, outcome assessments, and remote data collection methods.

    The Trials@Home RADIAL trial's regulatory record across six European countries: early and continuous engagement with regulators made the decentralised elements possible, and harmonised guidance is still needed where national legislation differs.

    This literature review maps the regulatory landscape for decentralised clinical trials across the US, EU and China, finding that the US emphasises efficiency and technological integration, the EU prioritises equity and patient engagement, and China focuses on rare diseases with a cautious regulatory approach. It argues that fragmented governance across jurisdictions hampers the full realisation of DCTs and calls for greater international harmonisation.
