Answered by Preet Kaur Gill

The UK Clinical Research Delivery key performance indicators (UKCRD KPI) report monitors the United Kingdom’s delivery of globally competitive clinical research. The table attached provides the requested figures for phase 1, phase 2, and phase 3 interventional clinical trials, by disease type.

They are an unpublished subset of statistics under indicator six of the UKCRD KPI report, which measures the number of participants recruited to clinical studies. The information is taken from studies recorded on the National Institute for Health and Care Research (NIHR) Research Delivery Network’s (RDN) Central Portfolio Management System.

The data was processed and assured by the NIHR RDN’s data, analytics, and specialty teams using the same established checks applied to data provided to the Department for publication in the UKCRD KPI report.
