Final Recruitment Figures

Since we opened back in 2005, up until the last comparisons finally closed to recruitment in 2023, almost 12,000 men have participated in the life-changing research of the STAMPEDE trial. Thank you to all the sites who have contributed to the success of the trial and who are still following up participants from the final comparisons.
