The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This randomized, double-blind. placebo-controlled study will assess the safety, tolerability, pharmacokinetics and pharmacodynamics of multiple doses of RO5310074 in patients with psoriatic arthritis who have or have had an inadequate response to oral disease-modifying antirheumatic drugs (DMARDs) or non-steroidal anti-rheumatic drugs (NSAIDs). Patients will be randomized in cohorts to receive either 6 intravenous doses of RO5310074 or placebo. Anticipated time on study treatment is 12 weeks.
