What this study is about

Researchers are testing whether N-acetylcysteine (NAC), a treatment, can help people with SLE. The trial will involve titrating to tolerance during an initial 3 month open label period and then subjects will be randomized to one of two arms. After A 3-month open-label dose-titration phase, SLE subjects will be randomized into 2 groups of 105 subjects either to continue the tolerated dosage of NAC or switched to equal number of placebo capsules.
