Rheumatoid Arthritis Extension Trial For Subjects Who Have Participated In Other PF-05280586 Trials (REFLECTIONS B328-04)

2019年1月8日 更新者:Pfizer

EXTENSION STUDY EVALUATING TREATMENT WITH PF-05280586 VERSUS RITUXIMAB IN SUBJECTS WITH ACTIVE RHEUMATOID ARTHRITIS WHO HAVE PARTICIPATED IN OTHER PF-05280586 CLINICAL TRIALS

This extension study will evaluate the safety (including immunogenicity) of treatment with rituximab-Pfizer, as well as the safety and immunogenicity after transitioning from rituximab-US or rituximab-EU to rituximab-Pfizer. This study will provide continued treatment access to subjects with active rheumatoid arthritis who have participated for at least 16 weeks in other studies in the rituximab Pfizer program.

The DAS assessment is a continuous composite measure derived using differential weighting given to the following 4 components: tender/painful joint count (28 joints), swollen joint count (28 joints), CRP and patient's global assessment of arthritis VAS. The formula for calculation of DAS28-CRP from these 4 components is DAS28-CRP = 0.56 sqrt (DAS 28 tender joint count) + 0.28 sqrt (DAS 28 swollen joint count) + 0.36 (ln CRP [mg/L] +1) + 0.014 (GH) + 0.96. Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28-CRP <2.6 implied remission.

大体时间:Week 1, 6, 13, and 25 (Course 1).

HAQ-DI assessed the degree of difficulty participants experienced in 8 daily living activity domains during a week: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and other activities. Each activity category consisted of 2-3 items. Each question's difficulty was scored from 0-3 (0=no difficulty, 1=some difficulty, 2=much difficulty, 3=unable to do). Activities requiring assistance (from people or assistive devices) were adjusted to ≥2 to denote more limited functional status. The questionnaire was to be completed by the participant prior to any procedures during the visit, if possible.

Overall HAQ-DI score was computed as the sum of domain scores divided by the number of domains answered, providing a score from 0-3. Low scores denoted improvement of disability/lower degree of domain difficulty.

Primary outcomes reported post baseline mean percent (%) changes in HAQ-DI score. Post baseline values are reported on the % change from initial study Baseline scale.
