Cost-effectiveness of apremilast in moderate to severe psoriasis in the United Kingdom

AbstractPurpose: Apremilast, an oral phosphodiesterase-4 inhibitor, is effective and well tolerated in the treatment of moderate-to-severe psoriasis. The cost-effectiveness of introducing apremilast before biologics was assessed from a UK payer perspective. Materials and methods: A 10-year Markov cohort model was developed to compare alternative treatment sequences: (1) apremilast followed by adalimumab and etanercept and (2) adalimumab followed by etanercept. Non-responders moved to the next treatment line, and patients for whom etanercept therapy failed continued on best supportive care (BSC) in both sequences. Response was defined as a ≥ 75% reduction in Psoriasis Area and Severity Index score (PASI-75) at the end of the trial periods (12‒16 weeks). A network meta-analysis provided efficacy inputs. Results: As a treatment-extension strategy, apremilast had an incremental cost-effectiveness ratio of £20,593 per quality-adjusted life-year gained versus the comparator sequence. PASI-75 was sustained for 0...
