The OCTAVE trial is still recruiting, and the full results will be reported once the trial is completed, which is likely to be towards the end of the year. Nevertheless, we recognise the importance of the results of this trial to many people in your position and for this reason, we are have releasing an early analysis of the OCTAVE results. These analyses are happening now and we will be releasing a pre-print reporting this interim results in the next few weeks and will make a summary of these interim results publicly available on our trial webpage birmingham.ac.uk/octave
