Brief summary
The main purpose of this study was to evaluate the safety and pharmacokinetics (PK, the action of a drug in the body over a period of time) of multiple intravenous (IV) administrations of CNTO 136 in patients with cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE). The secondary goal of this study was to assess the pharmacodynamics (biochemical and physiological effects of a drug and the mechanisms of action), immune response, and clinical response.
Detailed description
In Part A of this study, patients with CLE were randomly assigned (like flipping a coin) to receive multiple IV doses of CNTO 136, a human anti-IL 6 monoclonal antibody (an immune protein that binds to interleukin 6) or placebo (a substance that appears identical to the treatment and has no active ingredients). Patients and study personnel did not know the identity of the administered treatments (double-blind study). Increasing doses were given, based on safety data collected during the initial weeks of treatment. In Part B, which was also double-blind, patients with SLE were randomly assigned to receive multiple IV doses of the highest well-tolerated dose, as determined in Part A, of CNTO 136, or placebo.
