SMART Study: A Study of Re-treatment With MabThera (Rituximab) in Patients With Rheumatoid Arthritis Who Have Failed on Anti-TNF Alfa Therapy

10. September 2014 aktualisiert von: Hoffmann-La Roche

A Comparative Study to Assess the Effect of Retreatment With 2 Doses of MabThera on Disease Activity Score in Patients With Active Rheumatoid Arthritis Who Have Had an Inadequate Response or Intolerance to antiTNF-alfa Therapy.(SMART)

This study will compare the efficacy and safety of re-treatment with 2 doses of MabThera (rituximab) in patients with active rheumatoid arthritis (RA) who have previously experienced an inadequate response or intolerance to anti-tumor necrosis factor (anti-TNF) therapies etanercept, infliximab or adalimumab therapy. All patients will receive infusions of 1000 mg intravenous (IV) MabThera on Days 1 and 15; at Week 24 patients who have demonstrated a moderate or good response will be randomized to receive re-treatment with either 1 or 2 additional infusions of 1000 mg IV MabThera. The anticipated time on study treatment is 2+ years, and the target sample size is 100-500 individuals.

Zeitfenster
Disease Activity Score Based on 28-Joints Count and C-Reactive Protein (DAS28-CRP) Area Under the Curve (AUC) at Week 104
Zeitfenster: Week 104
DAS28-CRP was based on joint counts, overall participant assessment, and serum CRP levels (measured in milligrams per liter [mg/L]) at each visit. Joint counts included swollen joint count (SJC) and tender joint count (TJC). Total score range was 0 to 9.4; a higher score indicated more disease activity. DAS28-CRP less than or equal to (≤)3.2 implied low disease activity, >3.2 to 5.1 implied moderate to high disease activity, and less than (<)2.6 equals (=) remission. The AUC of all DAS28-CRP values between Day 1 and Week 104 (15 values of protocol visits) was calculated using the trapeze method (AUC between t1 and t2=(t2-t1)*((DAS28-CRP at t1 + DAS28-CRP at t2)/2). The true visit dates were used to calculate the time between 2 DAS28-CRP evaluations. All the AUC were censored at Week 104 (linear extrapolation using the 2 last DAS28-CRP values (Weeks 96 and 104) to obtain the "true" DAS28-CRP value at the "true" Week 104).

HAQ-DI was assessed in participants reporting acceptable symptom state using PASS (acceptance to remain for the rest of their lives with the level of disease activity they had during the last 48 hours). HAQ-DI is a participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0=least difficulty and 3 extreme difficulty.
Week 24, 12 and 24 weeks after 1st retreatment
Percentage of Participants With MCII in Functioning
Zeitfenster: Week 24, 12 and 24 weeks after 1st retreatment
Participants were asked how their functioning had been during the last 48 hours compared to baseline. Those participants that reported improvement assessed how important this improvement was to them; range: very important, moderately important, slightly important, or not at all important. Binary response options: 1=improved very important, or improved moderately important; 2=slightly important, not at all important, no change, or worse.

Change From Baseline in HAQ-DI in Participants With MCII

Baseline, Week 24, 12 and 24 weeks after 1st retreatment
Percentage of Participants With Acceptable Symptom State in Pain Assessed Using PASS
Zeitfenster: Week 24, 12 and 24 weeks after 1st retreatment
Percentage of participants reporting acceptable symptom state: acceptance to remain for the rest of their lives with the level of pain they had during the last 48 hours; and unacceptable symptom state: not able to remain for the rest of their lives with the level of pain they had during the last 48 hours. In the case of missing data, participants who withdrew from the study because of inefficacy or toxicity were considered "unacceptable".
Week 24, 12 and 24 weeks after 1st retreatment
Patient Global Assessment of Pain in Participants Reporting Acceptable Symptoms Using PASS
Zeitfenster: Week 24, 12 and 24 weeks after 1st retreatment
Patient Global Assessment of Pain assessed in participants reporting acceptable symptom state using PASS (acceptance to remain for the rest of their lives with the level of pain they had during the last 48 hours) on a 0 to 100 mm horizontal VAS by the participant. The left-hand extreme of the line equals 0 mm, and is described as "no pain" and the right-hand extreme equals 100 mm as "unbearable pain". Higher values correspond to worst state of participant (high pain levels).
Week 24, 12 and 24 weeks after 1st retreatment
Percentage of Participants With MCII in Pain
Zeitfenster: Week 24, 12 and 24 weeks after 1st retreatment
Participants were asked how their pain had been during the last 48 hours compared to baseline. Those participants that reported improvement assessed how important this improvement was to them; range: very important, moderately important, slightly important, or not at all important. Binary response options: 1=improved very important, or improved moderately important; 2=slightly important, not at all important, no change, or worse pain.
Week 24, 12 and 24 weeks after 1st retreatment
Change From Baseline in Patient Global Assessment of Pain in Participants With MCII
Zeitfenster: Baseline, Week 24, 12 and 24 weeks after 1st retreatment
The participants assessed their pain over the past 24 hours on a 0 to 100 mm horizontal VAS. The left-hand extreme of the line equals 0 mm, and is described as "no pain" and the right-hand extreme equals 100 mm as "unbearable pain". Participants were asked to mark the line and the distance from the left edge was measured. Higher values correspond to worst state of participant (high pain levels).
