|Systemic Lupus Erythematosus Arthritis||Drug: mycophenolate mofetil Other: placebo Drug: Mycophenolate mofetil||Not Applicable|
Patients and Methods:
27 patients with active BILAG B or A arthritis, with at least 6 swollen and 6 tender joints entered a six month study of MMF vs placebo for three months followed by open label MMF. 14 patients (12 women and 2 men) received placebo at baseline and 13 patients (11 women and 2 men) received MMF. Primary Outcome was Major Clinical Response at 3 months, then all patients received open label Cellcept for another 3 months. Blood was drawn for safety, lupus disease activity measures and exploratory Biomarkers, Joint counts were performed monthly. At baseline background DMARDs were stopped. Plaquenil was allowed. All patients received 160 mg depomedrol at baseline and were allowed 80 mg shots at subsequent months after blood draws and procedures had been completed.
At entry into the study, there was no difference between MMF and placebo in: age, gender, ethnicity, number of ACR criteria for lupus, or number of swollen and tender joints.
DEFINITION of RESPONSE
Prespecified Primary Endpoint: Complete Clinical Response:
BILAG C in musculoskeletal by Week 12 and decrease to 0.25 or less of tender +swollen jt counts
Prespecified Secondary Endpoint: Partial response:
One letter drop in musculoskeletal by Week 12 OR decrease to 0.5 or less tender + swollen jt counts
Exploratory Measure (not prespecified): Major Clinical Response:
BILAG C in musculoskeletal by Week 12 and decrease to 0.5 or less of tender +swollen jt counts. (In the primary analysis the one patient who met this endpoint was designated as a partial responder since those prespecified criteria were also met.
Does not meet above criteria for complete or partial response
Additional Measures: (prespecified secondary endpoints) included joint counts, changes in BILAG and SLEDAI and physician and patient global assessments.

Experimental: Arm I:
Participants randomly assigned to Arm I will receive mycophenolate mofetil in ascending doses during Month 1, and 3 grams/day (or less if there are tolerance issues) for Months 2 through 6.
Drug: mycophenolate mofetil
First treatment month: mycophenolate mofetil ascending doses orally Second treatment month to end of study: mycophenolate mofetil 3 gms/day (or less if tolerance issues arise)
Placebo Comparator: Arm 2a
Patients Randomly Assigned to Arm 2 will enter Arm 2a for three months as a placebo comparator. The placebo treatment will be structured so that they will undergo the same type of dosing in Month 1 that the ascending dose patient from Arm 1 undergo, but will have placebo in both bottles of pills. At the end of three months, after assessment of primary outcome, these patients enter Arm 2b which is a treatment arm.
oral placebo will be given in ascending "doses" during the first month and at full "dose" during the second and third month (or at lower "dose" if tolerance issues warrant)
Active Comparator: Arm 2b Open Lable Mycophenolate Mofetil
Arm 2b begins for patients in Arm 2 after three months. They will receive ascending doses of mycophenolate for the first month (which is Month 4 of the study). This will still be blinded since patients in Arm 1 will be undergoing an identical ascending dose regimen during this month, except that there will be active treatment in both bottles. At the end of Month 4 all patients will know that they are on full dose of 3 gms/day mycophenolate (or a lower dose if there are tolerance issues).
Drug: Mycophenolate mofetil
