Systemic lupus erythematosus (SLE) is a complex autoimmune disease of unknown etiology and limited available therapeutic options frustrating both clinicians and patients. However, recent advances in the understanding of disease mechanisms have given rise to numerous studies on specific approaches to SLE treatment. The purpose of this review is to explain the rationale for new treatments and results of the first clinical studies. We will focus on agents which deplete B cells (anti-CD20, anti-CD22), block cytokines (TNF α, Il 6), inhibit B/T cells interaction (CTLA-4Ig, anti-CD40L), or are even expected to reconstruct physiologic immunotolerance. Although preliminary results seemed promising, two randomized clinical trials with rituximab (EXPLORER and LUNAR study) failed to prove efficacy. Data analysis continues to explain the reasons. Trial design, subject population, limitations of the outcome measure instrument and site qualification have been questioned. Future studies are likely to focus on specific organ involvement or treatment combinations with other immunosuppressive agents.
