A Study of MabThera (Rituximab) in Patients With Rheumatoid Arthritis Who Have Failed on One Prior Anti-TNF Therapy (RESET)
- Registration Number
- NCT01272908
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This study will evaluate the safety and effectiveness of MabThera (rituximab) in patients with active rheumatoid arthritis who are receiving methotrexate, and who have a previous or current inadequate response to one prior anti-TNF therapy. All patients will receive MabThera 1000 mg as an intravenous infusion on days 1 and 15. After the initial study phase of 24 weeks, eligible patients may receive one re-treatment with MabThera. The anticipated time on study treatment is 48 weeks.

Percentage of Participants Meeting American College of Rheumatology (ACR) Response Criteria During the Initial Treatment Period Weeks 4, 12, 24, 36, and 48 of Initial treatment period ACR20/50/70, defined as ≥20 percent (%), 50%, or 70% improvement, respectively, compared to baseline in tender joint count (TJC) and swollen joint count (SJC), and 20%/50%/70% improvement in at least 3 of 5 additional ACR core set variables: Patient Assessment of Pain; Patient's Global Assessment of Disease Activity; Physician's Global Assessment of Disease Activity; Health Assessment Questionnaire - Disability Index (HAQ-DI); and an acute phase reactant (erythrocyte sedimentation rate \[ESR\] or C-Reactive Protein \[CRP\]). If CRP was missing or not done, then ESR was used.

Percentage of Participants Meeting European League Against Rheumatism (EULAR) Response Criteria During the Initial Treatment Period Weeks 4, 12, 24, 36, and 48 of Initial treatment period The EULAR response criteria were based on the assessment of disease activity using the DAS28. The EULAR response criteria included not only change in disease activity but current disease activity. To be classified as responders, participants had to have a significant change in DAS28 and a low current disease activity. There were 4 categories of EULAR response rates: good, moderate, good/moderate, and none. The DAS28 scoring used 4 core components: SJC, TJC, Patient's Global Assessment of Disease Activity, and ESR. The DAS28 has a continuous scale ranging from 0 to 9.4. The level of disease activity was interpreted as low (DAS28 score less than or equal to \[≤\]3.2), moderate (DAS28 score greater than \[\>\]3.2 but ≤5.1), or high (DAS28 score \>5.1). A DAS28 score \<2.6 corresponded to a state of remission according to American Rheumatism Association criteria.

Change From Baseline HAQ-DI Score During the Initial Treatment Period Weeks 4, 12, 24, 36, and 48 of Initial treatment period HAQ-DI: 20 questions, 8 categories of functioning: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and common usual activities. Participants report amount of difficulty in performing 2-3 specific subcategory items. Difficulty score is from 0 to 3 (0 = without any difficulty; 1 = with some difficulty; 2 = with much difficulty; and 3 = unable to do). The highest component score in each of the 8 categories determined the score for that category, unless aids, devices, and/or help from another person were required which = a score of 2 (unless already 2 or 3). The 8 category scores were averaged into overall HAQ-DI score ranging from 0 to 3 (0 to 1 = mild to moderate difficulty; 1 to 2 = moderate to severe disability; and 2 to 3 = severe to very severe disability). HAQ-DI not computed if \> 2 categories were missing.

Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Total Score During the Initial Treatment Period Weeks 4, 12, 24, 36, and 48 of Initial treatment period Participant fatigue was evaluated using the FACIT-F scale, a 13-item questionnaire in which the participants were requested to score each item on a 5-point scale. The FACIT-F scores ranged from 0 to 52, with higher scores representing less fatigue. Score changes of 4 points or more were considered clinically meaningful. The total score was a summation of all 13 items, where 2 of the positive items (I have energy; I am able to do my usual activities) were reversed for scoring.
