Summary
Brief summary (as posted)
This study will compare the safety and effectiveness of PF-05280586 versus rituximab-EU in patients with CD20-positive, low tumor burden follicular lymphoma. The primary hypothesis to be tested in this study is that the effectiveness of PF-05280586, as measured by the Overall Response Rate, is similar to that of rituximab-EU.

- timeFrame
- Week 26
- description
- ORR was defined as the percentage of participants who achieved complete response (CR) or partial response (PR) in accordance with the revised response criteria for malignant lymphoma (Cheson 2007). CR was defined as disappearance of all evidence of disease. PR was defined as regression of measureable disease and no new sites.
