Title

A Study to Assess the Effect of CellCept (Mycophenolate Mofetil) and Reduced Corticosteroids in Patients With Active Pemphigus Vulgaris (PV)
A Prospective, Randomised, Double-blind, Placebo-controlled, Parallel Group, Mult-center, 52-week Trial to Assess the Efficacy and Safety of Adjunct Mycophenolate Mofetil (MMF) to Achieve Remission With Reduced Corticosteroid in Subjects With Pemphigus Vulgaris

This study was designed to assess the efficacy and safety of CellCept (1 g or 1.5 g orally twice daily for 52 weeks) in patients with pemphigus vulgaris receiving prednisone or other corticosteroids. During the study, patients had their corticosteroid dose gradually reduced if they responded to treatment. The anticipated time on study treatment was 12 months, and the target sample size was <100 individuals.

Percentage of Patients Achieving Responder Status at Week 52

The proportion of subjects achieving responder status (defined as no new persistent lesions and prednisone dose of not more than 10 mg/day from Week 48 until study termination at Week 52) in the two active treatment groups combined (2 g/day and 3 g/day mycophenolate mofetil) compared with the placebo group

Time to Initial Response

Time to initial response defined as the time that the subject first demonstrated responder status (defined as no new persistent lesions and prednisone dose of not more than 10 mg/day from Week 48 until study termination at Week 52)

Time to Sustained Response

Time to sustained response is defined as the week the subject first demonstrates both of the conditions of responder status provided the conditions are maintained through to study termination at Week 52. If a subject does not have a sustained response, time to sustained response is censored on the last day of the study.
