NCT00307645

Brief Summary

The aim of IMPROVE is to define the optimal maintenance therapy for ANCA-associated vasculitides (AASV) by comparing the AZA (standard regimen) with MMF in terms of efficacy, i.e. in preventing relapses. HYPOTHESIS : MMF might be more effective than azathioprine as maintenance drug in AASV patients, reducing by 50% relapse rate, with a same frequency of adverse effects

Outcome Measures

Primary Outcomes (3)

  • the disease-free period, defined as the time between the beginning

  • of the maintenance therapy (AZA or MMF) and the first relapse (minor or major)

  • or the end of the protocol (at 48 months)

Secondary Outcomes (5)

  • relapse rate

  • rate of side-effects and intolerance

  • cumulative doses (AZA, CS, MMF)

  • AUC for BVAS, SF-36 or VDI

  • Evolution of titers of ANCA and CRP

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Newly diagnosed patients with WG, MPA or renal-limited vasculitis.
  • ANCA positivity. ANCA positivity requires PR3-ANCA or a typical cANCA pattern by indirect immunofluorescence (IIF), preferably confirmed by anti-PR3 ELISA. MPO-ANCA determined by ELISA requires demonstration of pANCA, and pANCA by IIF requires confirmation by anti-MPO ELISA. Optionally, central review of ANCA serology can be performed.
  • Age 18 to 75 years

You may not qualify if:

  • Any cytotoxic drug within previous year, unless started within one months of entry and according to the protocol design
  • Co-existence of another systemic autoimmune disease, e.g. SLE
  • Hepatitis B or Hepatitis C infection
  • HIV positivity
  • Failure to achieve remission after 6 months of CYC therapy
  • Failure to control progressive disease with induction protocol
  • Malignancy (usually exclude unless agreed with trial co-ordinator)
  • Pregnancy or inadequate contraception
  • Age below 18 and above 75 years\*
  • Inability for informed consent
  • After discussion with the trial administrator, patients less than 18 years may be incorporated on separate application according to the appropriate local ethic committee.
