PReS-FINAL-2134: Assessment of radiographic progression in patients (pts) with systemic juvenile idiopathic arthritis (sjia) treated with tocilizumab (TCZ): 2-year results from the tender trial
Pediatric Rheumatology volume 11, Article number: P147 (2013)
Objectives
To investigate progression of radiographic joint damage in pts with sjia treated with TCZ for up to 2 years in TENDER.
Methods
112 pts 2-17 yrs old with active, refractory sjia of ≥6 months' duration and inadequate response to previous non-steroidal anti-inflammatory drugs and oral corticosteroids were enrolled in TENDER. Pts were randomised 2:1 to receive TCZ according to body weight (12 mg/kg <30 kg or 8 mg/kg ≥30 kg) or placebo IV every 2 wks for 12 wks. Pts then received open-label TCZ in the ongoing long-term extension. Radiographic progression was calculated as change in adapted Sharp/van der Heijde score (ash) score and/or Poznanski score, assessed on hand and wrist radiographs, from baseline to wks 52 and 104. Radiographic progression was indicated by a positive ash score change or negative Poznanski score change. Clinical efficacy endpoints included American College of Rheumatology (ACR) Paediatric (Pedi) 70/90 responses.
Results
Baseline and ≥1 postbaseline ash and Poznanski scores were available for 47 and 33 pts, respectively (reasons for missing x-rays: early withdrawal, no consent, unreadable x-rays). Baseline characteristics for pts with radiographic data were similar to the whole TCZ population [1]. Pts with assessable ash/Poznanski scores had 5.2/4.8-yr disease duration, 21.3/19.2 active joints, 20.0/18.2 joints with limitation of movement and erythrocyte sedimentation rates of 53.9/59.2 mm/h. At wks 52 and 104, 20 and 19 pts, respectively, had ash progression, and 8 and 6 pts, respectively, had Poznanski score progression. Median change in ash score from baseline to wks 52 and 104 were 0 and 0.5, respectively (Table). Median change in Poznanski score from baseline to wks 52 and 104 were 0.3 and 0.17, respectively (Table 1).
Conclusion
Though changes in radiographic scores over time were seen in many pts, on average, pts with sjia did not experience noticeable progression of radiographic damage over 2 yrs of treatment with TCZ.
