Session Title: Spondyloarthropathies and Psoriatic Arthritis - Clinical Aspects and Treatment II

Session Type: Abstract Submissions (ACR)

Background/Purpose: Apremilast (APR) is a phosphodiesterase 4 inhibitor that helps to regulate the immune response that causes inflammation and skin disease associated with psoriatic arthritis (PsA). PALACE 1, 2, and 3 compared the efficacy and safety of APR with placebo in patients with active PsA despite prior disease-modifying antirheumatic drugs (DMARDs) and/or biologics, including biologic failures. We assessed the impact of baseline weight and body mass index (BMI) on clinical response to APR over 24 weeks in a pooled analysis.

Methods: Patients were randomized (1:1:1) to receive placebo, APR 20 mg BID (APR20), or APR 30 mg BID (APR30) stratified by baseline DMARD use (yes/no). Patients whose swollen and tender joint counts had not improved by ≥20% at Week 16 were considered non-responders and were required to be re-randomized (1:1) to APR20 or APR30 if they were initially randomized to placebo, or continued on their initial apremilast dose. At Week 24, all remaining placebo patients were re-randomized to APR20 or APR30.

Results: 1,493 patients were randomized, received ≥1 dose of study medication (placebo: n=496; APR20: n=500; APR30: n=497), and were comparable across treatment groups for demographics, disease characteristics, and prior/concurrent therapy. At baseline, mean (SD) weight was 85.7 (20.6) kg and mean (SD) BMI was 29.9 (6.5) kg/m2. At Week 16, a significantly greater proportion of patients receiving APR20 or APR30 achieved a modified ACR20 response vs placebo (primary endpoint) in all 3 PALACE trials. APR30 was associated with significant improvements in Health Assessment Questionnaire-Disability Index (HAQ-DI) score vs placebo at Week 16 (key secondary endpoint) across all 3 trials. At Week 16, similar ACR20 response rates and improvements in HAQ-DI scores were observed across all weight and BMI ranges (Table). A favorable treatment effect for both APR treatment groups vs placebo was observed, irrespective of baseline body weight or BMI. Overall, the treatment effect was dose-dependent, with greater effects generally observed in APR30 patients over APR20 patients. These treatment effects were generally maintained at Week 24.

Conclusion: APR demonstrated a favorable treatment effect in patients with active PsA. Comparable improvements in the signs and symptoms of PsA and physical function were observed across a broad range of baseline weight and BMI values. Results suggest that no dose adjustment is required to account for baseline body weight or BMI.
