Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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 endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
WA16291 is a Phase IIa "proof-of-concept" study. The primary objective of this study is to determine the safety and efficacy of rituximab (a B cell depleting chimeric monoclonal antibody) used either as monotherapy or in combination with methotrexate or cyclophosphamide in participants with rheumatoid arthritis who have failed prior Disease Modifying Anti-Rheumatic Drug (DMARD) therapy and currently have an inadequate clinical response to methotrexate.
