What if I don't want to carry on with the study?

We hope you will be able to continue to take the study pills for the full course of the study.

For the study to produce reliable results, it is necessary for participants to remember to take their study pills as best they can, and for the study team to collect complete information about the health of as many participants as possible.

Your participation is voluntary. It remains your right to decide you no longer wish to, or are no longer able to, participate in any aspect of the study at any time. All data as well as blood and urine samples already collected from you until the time you stop participating in the study will be kept and used as described below.

If you withdraw, your usual rights as an NHS patient will not be affected in any way.

If you are asked to stop your study pills by a doctor, or you choose to stop them yourself, it is important that the study team can stay in touch with you and you continue to attend study visits. To make sure the study produces reliable results we would also need, wherever possible, to continue to collect blood samples at the study clinics for the full trial duration (three to four years).

You may decide that you really do no longer wish to come to the study clinic. We would want to keep in touch by other methods. There is more detail in the accompanying Data Protection Information Leaflet.
