Participant Flow

All patients will attend a pre-entry Visit 3-28 days before the planned randomisation. At this Visit, the Investigator ensures that a signed Informed Consent Form has been obtained before any study specific procedures are conducted. Patients who have given their consent to participate in the study will then undergo a full clinical assessment
