Abstract
Background/Aims
SKIPPAIN (NCT03136861) is the first randomised controlled study involving a biological disease-modifying anti-rheumatic drug, with a primary endpoint of spinal pain at Week 8 in patients with axial spondyloarthritis (axSpA; ankylosing spondylitis [AS] and non-radiographic [nr]-axSpA). We present the 24-week results of secukinumab in reducing spinal pain and disease activity following step-up dosing.
Methods
This double-blind, placebo-controlled Phase 3b study enrolled patients (aged ≥18 years) with active disease (BASDAI ≥4; average spinal pain numerical rating scale [NRS] score >4 at baseline; inadequate response to ≥ 2 non-steroidal anti-inflammatory drugs ≥4 weeks). Patients were randomised (3:1) to subcutaneous secukinumab 150 mg or placebo weekly followed by every 4 weeks (Q4W) from Week 4. At Week 8, placebo patients were re-randomised to secukinumab 150 or 300 mg Q4W. Patients originally randomised to secukinumab 150 mg were classified as responders or non-responders (spinal pain NRS score <4 or ≥ 4, respectively) at Week 8. Responders were re-assigned to continue doubleblind secukinumab 150 mg Q4W (Arm A1). Non-responders were re-randomised to double-blind secukinumab 150 mg (Arm A2) or a step-up dose of 300 mg (Arm A3) Q4W. Treatment was up to Week 24. Primary endpoint: proportion of patients achieving an average spinal pain score <4 on a 0-10 NRS with secukinumab vs placebo at Week 8.
Results
380 axSpA patients (269/380 [70.8%] AS; 111/380 [29.2%] nr-axSpA) were randomised to secukinumab 150 mg (N = 285) or placebo (N = 95). The primary endpoint was met (proportion of spinal pain NRS [average] score responders: 32% vs 20%; odds ratio [95% confidence interval] 1.9 [1.1-3.3] favouring secukinumab vs placebo; P < 0.05). Further reductions in spinal pain occurred at Week 24, especially in those initially randomised to placebo and switched to active drug. Pronounced improvements were observed in other disease activity measurements (Table 1). Numerically, more patients achieved ASDAS low disease activity at Week 24 post-secukinumab dose escalation (Arm A3) vs those remaining on the same dose (Arm A2).
Conclusion
Secukinumab provided rapid, significant improvement in spinal pain and led to low disease activity in axSpA patients. Secukinumab dose escalation might be beneficial for patients not responding fully to the starting dose.
