CellCept in p-ANCA Vasculitis
|MPO-ANCA Vasculitis Microscopic Polyangiitis||Drug: CellCept (mycophenolate mofetil)||Phase 1|
|Study Design:||Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Pilot Study of Mycophenolate Mofetil (MMF) in Patients With p-ANCA Microscopic Polyangiitis and Mild to Moderate Renal Dysfunction.|
- The primary endpoint is successful induction of remission as defined in Appendix 6 within 6 months.
- Major relapse necessitating a switch to induction OCS/CYC treatment or more aggressive treatment (e.g. plasma exchange).
- Minor relapses that can effectively be controlled by a transient, non-toxic increase in OCS
- Intolerance to trial medications and adverse effects. Adverse effects will be monitored
|Study Start Date:||December 2002|
|Study Completion Date:||July 2008|
|Primary Completion Date:||July 2008 (Final data collection date for primary outcome measure)|
- Patients will receive I.V. methylprednisone, or I.V. dexamethazone, oral prednisone and oral MMF therapy as outlined in table 2.
- MMF will be initiated within the first 1-2 weeks of the start of steroids. Patients will receive CellCept, 750 mg po b.i.d for the first week. Dose will be increased to 1000 mg po b.i.d for the second week, and thereafter, according to blood levels and patient tolerance. Target blood levels are 1 ? 3.5 g/ml. Treatment will be for a total of 18 months. This is based on the published dose-dependent adverse effect profiles in transplant patients (31-32) and on reports that lower doses are ineffective and shorter courses (less then 6 months) result in relapses or failure of therapy (25). Dose will be reduced in patient who can not tolerate MMF at the above dose.
2) Relapse treatment to follow guidelines for relapse regimens. 3) After 18 months, all medications will be tapered to a full stop unless disease is active or grumbling.
4) Pneumocystis pneumonia prophylaxis will be used during the trial (with sulfamethoxazole/trimethoprim, or Dapsone or Mepron if allergic to sulfa).
