Innovative Anti-pneumococcal Vaccine Strategies in Patients With ANCA-associated Vasculitis Receiving Rituximab Therapy
France96 participantsStarted 2018-02-05
Plain-language summary
The study hypothesis is that a "reinforced" pneumococcal combined vaccine strategy in patients with ANCA-associated vasculitides treated with rituximab will induce a better immune response than the current standard regimen, with an acceptable safety profile.
This study therefore aims at evaluating the immunogenicity and safety of two "reinforced" innovative pneumococcal vaccine regimen \[one double dose at day0 and one double dose at day7 or a quadruple dose of 13-valent anti-pneumococcal conjugate vaccine (PCV13) followed by one dose of 23-valent unconjugated vaccine (PPV23) at month 5\], compared to the standard regimen (one dose of PCV13 followed by one dose of PPV23 at month 5), in patients with ANCA-associated vasculitides receiving rituximab therapy.

Inclusion criteria
. Participants with a diagnosis of ANCA-associated vasculitis, either granulomatosis with polyangiitis (GPA, Wegener) or microscopic polyangiitis (MPA), according to ACR 1990 criteria and/or revised Chapel Hill Consensus Conference definitions and/or European Medical Agency algorithm
. Participants (males and females) aged of 18 years or older
. Participants with childbearing potential having reliable contraception for all the duration of the study, such as established use of oral, injected or implanted hormonal methods of contraception; placement of an intrauterine device (IUD) or intrauterine system (IUS); barrier methods: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository; male partner sterilization (the vasectomized partner should be the sole partner for that subject); surgical sterilization (hysterectomy, bilateral oophorectomy, tubal ligation) or true abstinence (when this is in line with the preferred and usual lifestyle of the subject) prior to enrollment at D0
. Participants with newly-diagnosed disease at the time of inclusion or presenting with a relapse of the disease. For relapsing patients, maintenance therapy at stable dose during the last 3 months will be admitted : prednisone dose ≤10 mg/day, azathioprine dose ≤3 mg/kg/day, methotrexate dose ≤25 mg/week, or mycophenolate mofetil dose ≤3 g/j
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
