Regulators in Europe and the U.K. unveiled measures to accelerate multinational trial starts. The EU launched FAST‑EU, a voluntary pilot aiming for a 70‑day timeline from filing to trial start, while the U.K. will implement new clinical trial rules on April 28 that include a 14‑day assessment route for some Phase I studies and faster review lanes for lower‑risk trials. Both initiatives seek to cut administrative lead times and increase trial competitiveness. Sponsors should expect new timelines and prepare for harmonized dossier standards and possible fast‑track pathways for low‑risk multicenter studies.
