First received: May 19, 2008
Last updated: May 23, 2008
Last verified: May 2008
The efficacy and safety of CellCept (1g po, bid for 36 weeks) will be assessed in patients with myasthenia gravis receiving prednisone, or other corticosteroids. During the study, patients will undergo gradual corticosteroid dose reduction, if they respond to treatment. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Condition Intervention Phase
Myasthenia Gravis, Generalized Drug: mycophenolate mofetil (CellCept) Drug: placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Prospective, Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Multicenter, 36-Week Trial to Assess the Efficacy and Safety of Adjunct Mycophenolate Mofetil (MMF) to Maintain or Improve Symptom Control With Reduced Corticosteroid in Subjects With Myasthenia Gravis
