Real-World Efficacy and Safety of Apremilast in Belgian Patients with Psoriatic Arthritis: Results from the Prospective Observational APOLO Study

Journal Contribution - Journal Article

INTRODUCTION: Apremilast is approved for the treatment of psoriasis and psoriatic arthritis (PsA). Real-world evidence on the efficacy and safety of apremilast in clinical practice is limited. We assessed the use of apremilast in patients with PsA in Belgium clinical practice. METHODS: The multicentre, observational, prospective APOLO study enrolled patients with active PsA initiating apremilast in Belgium between April 2017 and December 2018. Primary outcome was PsA Response Criteria (PsARC) after 6 months of apremilast treatment. Secondary outcomes included PsA Impact of Disease 12 (PsAID12) and Health Assessment Questionnaire Disability Index (HAQ-DI). Disease-specific outcomes and patient-reported outcomes (PROs) were analysed for patients who received apremilast within 30 days prior to their study inclusion and completed at least 150 days of treatment (reference set [REF]). RESULTS: Of 107 patients enrolled in the study, 106 received at least one dose of apremilast and 69 were included in the REF. PsARC response was achieved by 43.5% of patients (30/69) in the REF at month 6; mean global and composite scores including 68-joint count for pain/tenderness (68-TJC) and 66-joint count for swelling (66-SJC) improved, and 27% and 42% of patients with 68-TJC and 66-SJC > 0 at baseline had complete joint count resolution, respectively. Mean global and composite PsAID12 and HAQ-DI scores decreased at 6 months, indicating improved quality of life. Apremilast was well tolerated and the reported adverse events were in line with the known safety profile. CONCLUSION: Results from the APOLO study indicate that treatment with apremilast in Belgian clinical practice improves the signs and symptoms of PsA as well as patient quality of life.
