BackgroundAtopic dermatitis (AD) is a chronic, multifactorial, inflammatory skin disease with significant impact on patients’ quality of life. ObjectiveThe objective of this analysis was to estimate the incremental cost-effectiveness ratio (ICER) of dupilumab, administered every other week, vs supportive care (SC), in the Italian adult population with severe AD, for whom ciclosporin treatment is contraindicated, ineffective or not tolerated. MethodsSimulation of outcomes and costs was undertaken using a 1-year decision tree, followed by a 20-year time horizon Markov model. Clinical data were derived from a pooled analysis of two studies. Given the uncertainty on final National Health Service (NHS) cost of dupilumab in Italy (confidential discount might be applied) multiple cost-utility analyses were conducted using different price hypotheses, starting from dupilumab published ex-manufacturer price, and progressively reducing it up to 50%. Model robustness were tested using sensitivity analyses. ResultsIn the base-case, dupilumab was more effective than SC (+1.92 quality adjusted life years, QALYs). In Analysis A (NHS perspective), -8.0% discount on dupilumab ex-manufacturer price was required to achieve an ICER

We considered all patients aged ≥18years with a diagnosis of RA and at least one biologic drug prescription between January 2010 and December 2012 (recruitment period). Persistence was defined as maintenance over the last 3months of the follow-up period of the same biological therapy administered at the index date. A switch was defined as the presence of a biological therapy other than that administered at the index date during the last 3months of the follow-up period. Hospital admissions (with a diagnosis of RA or other RA-related diagnoses), specialist outpatient services, instrumental diagnostics and pharmaceutical consumption were assessed.Results: The drug utilization analysis took into account only biologics with at least 90 patients on treatment at baseline (adalimumab n=144, etanercept n=236 and infliximab n=94). In each year, etanercept showed better persistence with initial treatment than adalimumab or infliximab. Etanercept was characterized by the lowest number of patients increasing the initial drug consumption (2.6%) and by the highest number of patients reducing the initial drug consumption (10.5%). The mean cost of treatment for a patient persisting with the initial treatment was €12,388 (€14,182 for adalimumab, €12,103 for etanercept and €11,002 for infliximab). The treatment costs for patients switching from initial treatment during the first year of follow-up were higher than for patients who did not switch (€12,710 vs. €11,332).Conclusion: Persistence, switch rate and drug consumption seem to directly influence treatment costs. In subjects not persisting with initial treatment, other health care costs were approximately three times higher than for persistent patients. This difference could suggest a positive effect on the quality of life for persistent patients. Etanercept showed the highest persistence with treatment.

Objective To evaluate the efficiency of resources allocation and sustainability of the use of netupitant+palonosetron (NEPA) for chemotherapy-induced nausea and vomiting (CINV) prophylaxis assuming the Italian National Health Service (NHS) perspective. A published Markov model was adapted to assess the incremental cost-utility ratio of NEPA compared with aprepitant (APR) + palonosetron (PALO), fosaprepitant (fAPR) + PALO, APR + ondansetron (ONDA), fAPR + ONDA in patients receiving a highly emetogenic chemotherapy (HEC) and with APR + PALO and fAPR + PALO in patients receiving a moderately emetogenic chemotherapy (MEC). Setting Oncology hospital department in Italy. Methods A Markov model was used to determine the impact of NEPA on the budget of the Italian NHS on a 5-day time horizon, corresponding to the acute and delayed CINV prophylaxis phases. Direct medical costs considered were related to antiemetic drugs, adverse events management, CINV episodes management. Clinical and quality of life data referred to previously published works. The budget impact analysis considered the aforementioned therapies plus PALO alone (for HEC and MEC) on a 5-year time horizon, comparing two scenarios: one considering the use of NEPA and one not considering its use. Primary and secondary outcome measures Incremental cost per quality adjusted life year (QALY) and differential economic impact for the Italian NHS between the two scenarios considered. Results NEPA is more effective and less expensive (dominant) compared with APR + PALO (for HEC and MEC), fAPR + PALO (for HEC and MEC), APR + ONDA (for HEC), fAPR + ONDA (for HEC). The use of NEPA would lead to a 5-year cost decrease of €63.7 million (€42.7 million for HEC and €20.9 million for MEC). Conclusions NEPA allows an efficient allocation of resources for the Italian NHS and it is sustainable, leading to a cost decrease compared with a scenario which does not consider its use.
