It will also be made clear at this stage, on information sheets and throughout the study that participants can withdraw from the study at any time without it affecting their routine care in any way.

Discontinuation of study participation after commencement of CD-TREAT would therefore involve return to standard induction treatment at the discretion of the treating clinical team.
