Today the Data Safety Monitoring Committee (DSMC) gave the recommendation to continue randomisation as planned. Their analysis is based on the 1200 randomisations up until August 2019. This is the only planned formal interim analysis in the trial. With 1520 participants randomised today and 380 to go we are anticipating a completion date in the beginning of 2020.
