Question to the Department of Health and Social Care:

To ask His Majesty's Government how many clinical trials offering CAR-T therapy for low-grade lymphoma have closed in the last three years, and what the reasons were in each case.

Answering this question would require Medicines and Healthcare products Regulatory Agency staff to go through a vast volume of protocol documents manually. This is because the information is not held in such a way to be able to filter electronically by the requested category.

The Guide to Parliamentary Work sets out that there is an advisory cost limit known as the disproportionate cost threshold which is the level above which departments can decide not to answer a written question. The current disproportionate cost threshold is £850.

The Guide to Parliamentary Work is published online and is available on the GOV.UK website.
