The ROCKet trial will complete recruitment in the first quarter of 2025. There are 4823 patients randomised and every patient counts as we orbit to the end. We encourage current recruiting sites to push on with only 61 patients to go. Data cleaning is in progress and we urge all sites to prioritise data entry.
