Participants will be eligible if they are treated with background medication to control their vasculitis disease and have a low level of disease activity as defined by a Birmingham Vasculitis Activity Score (BVAS) of greater than 3.\n\nParticipants will be randomly placed in 1 of 2 groups. Both groups will be given background medication. One group will receive hydroxychloroquine and the other will receive placebo. Participants will be on treatment for 1 year.\n\n76 ANCA Vasculitis participants will be recruited (38 in each treatment arm) from UK vasculitis specialist centres.', 'detailedDescription': "This is a multi-centre, randomised, placebo-controlled, double-blind study to evaluate if hydroxychloroquine in combination with background maintenance therapy improves the clinical response and quality of life in patients with AAV. 76 participants who have Granulomatosis with Polyangiitis, Microscopic Polyangiitis or Eosinophilic Granulomatosis with Polyangiitis will be recruited from 20 sites.\n\nThey will be randomised in a 1:1 ratio of hydroxychloroquine or placebo. Neither the patient nor the research team will know which treatment group the participant is in.\n\nOnce the participant agrees to take part and has signed informed consent, they will undergo the following assessments, tests and procedures to find out if they can take part in the study. Some may be routinely done by the study doctor as part of regular vasculitis care even if the participants are not in the study:\n\n* Medical history\n* Birmingham Vasculitis Activity Score (BVAS)\n* Physical exam\n* Blood tests\n* Pregnancy test\n* Urine drug test\n* Electrocardiogram\n\nIf the patient is eligible to take part in the study, they will be randomised to receive either hydroxychloroquine or placebo in addition to background medication. Participants will receive 2 tablets to take once a day over the course of a year. Participants may have their dose reduced to 1 tablet dependent on their weight at baseline and renal function. All participants will have their prednisolone dose tapered down over the course of the study. Participants will be asked to fill in a patient diary on a weekly basis to record whether they've taken their medication, and if they've experienced any change of symptoms.\n\nParticipants will be asked to attend the hospital at weeks 4, 16, 28, 40, 44, 48, 52 and 56. At each of these visits, participants will undertake some or all of the following tests/assessments:\n\n* Physical exam including visual acuity\n* Weight and vital signs\n* BVAS assessment and Vasculitis Damage Index (VDI)\n* Patient questionnaires\n* If there are any changes to their medicines and health status\n* If they experiencing any side effects\n* Blood samples and urine tests to see how the study drug is affecting the body.\n* At two visits, participants will also be asked to undergo an electrocardiogram (ECG).\n\nPatients will be followed up by phone in weeks 10, 22, and 34. This phone call will be based on the ANCA-associated Vasculitis Patient Reported Outcome (AAV PRO) questionnaire and patients will also be encouraged to report any adverse events. Patients reporting new or worsening symptoms will be invited to the hospital for an unscheduled visit.\n\nIn addition to clinical bloods, 76ml of blood will be taken for research purposes for all participants. These will be taken at the same time as clinical bloods to minimise discomfort for the participant. Participants at Guy's and St Thomas' will have an additional 200ml of blood taken for isolation of cells. These bloods will be stored and kept for future research, with the written consent of the participant."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria\n\n1.
