This 2 arm study will compare the safety and efficacy, with regard to reduction of signs and symptoms, of tocilizumab versus placebo in combination with traditional Disease-Modifying Anti-Rheumatic Drug (DMARD) therapy in patients with moderate to severe active rheumatoid arthritis (RA) who have had an inadequate response to current DMARD therapy.

Varicella zoster virus causes chickenpox in children and shingles in adults. Chickenpox is usually a self-limiting illness characterized by fever and a rash. Serious complications can include secondary bacterial infections, pneumonia, and encephalitis. Anti-viral treatment is not a standard of care in immunocompetent children, but is recommended whenever a risk of complication exists. This study will evaluate the safety and blood levels of a new formulation of famciclovir in children 1-12 years of age.
BBR 2778 is a novel aza-anthracenedione that has activity in experimental tumors and shows reduced potential for cardiotoxicity in animal models.
