Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, pursuant to the Answer of 10 November 2014 to Question 213584, which clinical trials will run over (a) three and (b) five years; and what estimate he has made of the number of patients who will take part in each such trial.

NHS England advise that questions about the running of clinical trials should be directed to the trial sponsor. In the case of clinical trials for stereotactic ablative radiotherapy the sponsor is Cancer Research UK.

The current assessment of the number of patients that will be recruited to the trials is a provisional estimate and it is important to note that this will vary dependent on a number of factors, including local recruitment and randomisation to different trial arms.
