Question to the Department of Health and Social Care:
To ask the Secretary of State for Health and Social Care, how many phase (a) one, (b) two and (c) three dementia clinical trials there have been in the UK in each of the last ten years; and how many participants were recruited for each of those trials.
The Department delivers dementia research via the National Institute for Health and Care Research (NIHR). The Department does not hold information centrally on clinical trials hosted in Wales and Scotland. The Department is therefore unable to provide how many phase one, phase two, and phase three clinical trials for dementia have taken place in Wales and Scotland in each of the last 10 years.
The following table shows the number of phase one, two, and three trials in England for dementia, supported by the NIHR Research Delivery Network, from 2014/15 to 2023/24:
Year | Phase 1 | Phase 2 | Phase 3 |
2014/15 | - | 12 | 17 |
2015/16 | 1 | 15 | 18 |
2016/17 | - | 12 | 24 |
2017/18 | 1 | 14 | 26 |
2018/19 | 1 | 12 | 18 |
2019/20 | 2 | 13 | 6 |
2020/21 | 1 | 8 | 8 |
2021/22 | 2 | 13 | 11 |
2022/23 | 4 | 11 | 11 |
2023/24 | 4 | 13 | 9 |
In addition, the following table shows the number of participants recruited into phase one, two, and three trials in England for dementia, supported by the NIHR Research Delivery Network, from 2014/15 to 2023/24:
Year | Phase 1 | Phase 2 | Phase 3 |
2014/15 | - | 755 | 663 |
2015/16 | 10 | 843 | 1,165 |
2016/17 | - | 464 | 625 |
2017/18 | 3 | 415 | 471 |
2018/19 | 12 | 577 | 7,473 |
2019/20 | 4 | 600 | 440 |
2020/21 | 2 | 48 | 46 |
2021/22 | 6 | 35 | 61 |
2022/23 | 4 | 68 | 75 |
2023/24 | 15 | 123 | 190 |
Note: studies are sometimes conducted across multiple phases, for example a study may cross phase one/two or phase two/three. Therefore, figures cannot be totalled.
