Summary

This trial is a phase II study to test the safety and efficacy of N-acetyl cysteine (NAC) in treating systemic lupus erythematosus (SLE). SLE is a chronic inflammatory disease which often has debilitating and potentially life-threatening consequences. The cause of SLE is unknown and current therapies lack specificity and carry significant side-effects. This study will have two groups of 105 subjects each, with one group continuing the tolerated dosage of NAC and the other group switched to placebo capsules. The study will last 13 months with seven study visits per subject. Each subject will donate approximately 100 ml of blood

Who is the study for?
Adults over 18 with active Systemic Lupus Erythematosus (SLE) can join this trial. They should have a certain level of disease activity but not in the kidneys or central nervous system, and be on stable medication doses for SLE. People who are pregnant, breastfeeding, recently in other trials, or have serious health issues like heart failure cannot participate.
What is being tested?
The study tests N-acetylcysteine (NAC), an antioxidant thought to help with SLE symptoms by adjusting glutathione levels. Participants will first find a tolerable dose over three months before being randomly assigned to continue NAC or switch to placebo for another ten months.
What are the potential side effects?
Potential side effects of N-acetylcysteine may include nausea, vomiting, rash, and headache. However, since it's an antioxidant supplement commonly used for other conditions as well, severe side effects are generally rare.
