研究概览
简要总结
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.

结局指标
主要结局
Overall Response Rate (ORR): Percentage of Participants With Overall Response (OR) at Week 26
时间窗: Week 26
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.
次要结局
- Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)(Baseline up to Week 52)
- Number of Participants With Clinically Significant Laboratory Abnormalities(Baseline up to Week 52)
- Number of Participants With Grade 3 or Higher Treatment-Related Treatment-Emergent Adverse Events (AEs) as Graded by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 4.03(Baseline up to Week 52)
- Percentage of Participants With Complete Remission (CR) at Week 26(Week 26)
- Duration of Response (DOR)(From date of first documentation of overall response to first documentation of PD or to death due to any cause in absence of PD or up to Week 52)
- Time to Treatment Failure (TTF)(From randomization until disease progression, death or permanent discontinuation from treatment/study due to any reason, or up to Week 52)
- Progression-Free Survival (PFS)(From randomization until disease progression or death due to any cause or up to Week 52)
- Overall Survival(From randomization until death due to any cause or up to Week 52)
- Number of Participants With Treatment Related Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)(Baseline up to Week 52)

- Cluster of Differentiation (CD) 19-Positive B-Cell Counts(Baseline, Week 2, 3, 4, 5, 13, 26, 39, 52)
- Number of Participants With Positive Anti-Drug Antibodies (ADAs) and Neutralizing Antibodies (NAbs)(Baseline up to Week 52)
- Minimum Observed (Trough) Serum Concentration (Ctrough) of PF-05280586 and Rituximab-EU(Predose (within 4 hours prior to the start of dosing) on Day 1, 8, 15, and 22)
- Number of Participants Reporting Immune-Based Adverse Effects(Baseline up to Week 52)
