Randomized Controlled Trial Multicenter StudyA phase IIb dose-ranging study of the oral JAK inhibitor tofacitinib (CP-690,550) versus placebo in combination with background methotrexate in patients with active rheumatoid arthritis and an inadequate response to methotrexate alone.
To compare the efficacy, safety, and tolerability of 6 dosages of oral tofacitinib (CP-690,550) with placebo for the treatment of active rheumatoid arthritis (RA) in patients receiving a stable background regimen of methotrexate (MTX) who have an inadequate response to MTX monotherapy. ⋯ In patients with active RA in whom the response to MTX has been inadequate, the addition of tofacitinib at a dosage ≥3 mg twice daily showed sustained efficacy and a manageable safety profile over 24 weeks.

Randomized Controlled TrialEfficacy and safety of rituximab in patients with active proliferative lupus nephritis: the Lupus Nephritis Assessment with Rituximab study.
To evaluate the efficacy and safety of rituximab in a randomized, double-blind, placebo-controlled phase III trial in patients with lupus nephritis treated concomitantly with mycophenolate mofetil (MMF) and corticosteroids. ⋯ Although rituximab therapy led to more responders and greater reductions in anti-dsDNA and C3/C4 levels, it did not improve clinical outcomes after 1 year of treatment. The combination of rituximab with MMF and corticosteroids did not result in any new or unexpected safety signals.
