i Patients will be followed up by telephone at weeks 10, 22 and 34 rather than visiting the study centre. The phone call will be structured using the AAV pro questionnaire. See section 6.13 for more details

ii To be arranged if a patient withdraws from the trial but is willing to have a final study visit. This is only necessary in instances where the patient’s last visit was more than 4 weeks ago

iii The eye screen is only required for patients whose eGFR drops below 60ml/min at any point during the trial. The eye screen should take place between week 52 and week 56 visits by a local optometrist

iv The eligibility criteria require BVAS to be scored and for female patients to have a pregnancy test at baseline as well as screening. Other screening procedures do not need to be repeated

v Vital signs to include BP, pulse, respiration rate and temperature

vi BVAS and VDI to be scored locally following training. BVAS scores will be quality checked by a central adjudication panel to ensure consistency

vii Telephone follow up interviews will only use the AAV Pro questionnaire to structure the conversation. The SF-36, EQ5D and HAQ questionnaires will not be included

viii Where ESR is not available, plasma viscosity may be used instead

ix If the patient’s eGFR drops below 60ml/min at any point of the trial they should be invited for an eye screen between week 52 and 56

x If the baseline visit is less than two weeks after screening, these tests do not need to be performed again

xi Protein:creatinine ratio only needs to be performed if urine dipstick for protein shows 1+ or more, but results can be collected if routinely performed when the urine dipstick is negative

xii Patients who test positive for hepatitis B surface antigen, hepatitis B core antibody, hepatitis C antibody or HIV-1 will be excluded

xiii Urine pregnancy test

xiv Plasma and serum collected at all sites. Cells at Guy’s Hospital only

xv Samples only collected if the patient is identified as having a flare
