Accruals

This page provides figures for ‘accruals’ or the number of people ‘recruited’ to cancer trials in Ireland. 

Note: While Cancer Trials Ireland makes every effort to track numbers for all trials in Ireland, in some instances this is not possible. The figures below therefore are accurate for 95%+ of all trials in Ireland.

Overall numbers: 2019 v 2020

The figures below include every type of trial – interventional / drug trials, translational trials (observational studies), radiotherapy trials, industry trials. This is intended to be useful to media, and members of the public seeking a snapshot of the number of patients recruited to cancer clinical trials in Ireland for a given period of time (in this case, calendar year). 

  • 2019: 1,017 patients recruited
  • 2020: 806 patients recruited

Thus we saw a drop of 20.7% in patients recruited to trials in Ireland. 

Overall numbers: Q1 2020 v Q1 2021

The figures below include every type of trial – interventional / drug trials, translational trials (observational studies), radiotherapy trials, industry trials.  

  • 2020, Q1: 324 patients recruited
  • 2021, Q1: 179 patients recruited

Thus we saw a drop of 44.75% in patients recruited to trials in Ireland. 

Detailed breakdown for Q1 2019 v 2020

WARNING: Once again, if you are not working in the cancer trials community, you should not interpret the figures below without assistance from Cancer Trials Ireland. While COVID19 has impacted the number of patients recruited to trials, there may be other factors contributing to a decrease/increase in recruitment.

What does ‘CTRIAL’ mean?

This refers to studies that have a Cancer Trials Ireland code, because it is a study in which we play an active part, or because it is a study we have ‘adopted’ into our portfolio, in order to include it in DSSG meeting discussions, and for other reasons. 

What does ‘Non-CTRIAL’ mean? 

This refers to studies whose recruitment numbers we track, but which Cancer Trials Ireland is not involved with in any capacity. Our objective in tracking recruitment numbers on these trials, and CTRIAL trials, is to provide the fullest picture possible for the number of people joining cancer trials in Ireland.   

NOTE: When the accrual figures for Q2 2021 are published (July 2021) we will include the breakdown of trial recruitments by disease areas, i.e. Lung/breast/gynae etc.
