Introduction: In recent years, target therapies to specific molecular alterations in advanced non-small cell lung cancer (NSCLC) have been identified and have shown superior efficacy compared to non-targeted treatments. Anaplastic lymphoma kinase (ALK) is one of the therapeutic targets; nevertheless, ALK diagnosis is not performed in all NSCLC patients in Spain. The objective of this study is to estimate in monetary terms the benefit for the Spanish society of ALK diagnosis in advanced NSCLC patients.

Methods: A cost-benefit analysis of ALK diagnosis vs. non-diagnosis in advanced NSCLC patients was carried out from the Spanish social perspective, with a time horizon of 5 years. Costs, benefits and the cost-benefit ratio were measured. The analysis has considered the overall survival in advanced NSCLC patients treated with the ALK-tyrosine kinase inhibitor (TKI) alectinib. The natural history of NSCLC was simulated using a Markov model. A 3% discount rate was applied to both costs and benefits. The result was tested using a deterministic sensitivity analysis.

Results: The cost of ALK diagnosis vs. non-diagnosis in the base case would be €10.19 million, generating benefits of €11.71 million. The cost-benefit ratio would be €1.15. In the sensitivity analysis, the cost-benefit ratio could range from €0.89 to €2.10.

Conclusions: The results justify the universal application of ALK diagnosis in advanced NSCLC, which generates a benefit for Spanish society that outweighs its costs and allows optimal treatment with targeted therapies for these patients.

Haemophilia B (HB) is a rare disease which may lead to chronic disabling arthropathy, resulting in a significant clinical, social and economic impact. In recent years, new extended half-life (EHL) factor IX concentrates produced by recombinant technology (rFIX) have been developed. They have shown significantly prolonged half-life as compared to other rFIX products and improved bleeding control when used as prophylaxis. To date, EHL rFIX products reimbursed in Italy are a recombinant coagulation factor IX produced with Fc technology (rFIXFc) and a recombinant fusion protein containing rFIX fused with recombinant albumin (rIX-FP). The results of extension studies with injection intervals with a median of almost every 14 days for the complete individualized interval prophylaxis (IP) group on rFIXFc and 21 days for a selected subgroup of patients on rIX-FP have recently been published. The aim of this analysis was to estimate the cost of prophylactic treatment with rFIXFc and rIX-FP in adult patients, in the light of new clinical evidence and current average prices in Italy. The cost of therapy was estimated on the basis of the results of extension studies, the average prices reported in regional drug tenders and assuming an average patient weight of 70 kg. The analysis estimated a cost per patient/year between €224,407 and €230,355 for rFIXFc and between €242,259 and €368,587 for rIX-FP. The sensitivity analysis confirmed the robustness of the results. The use of rFIXFc over rIX-FP proves to be the least expensive choice for the treatment of HB in Italy.

Introduction: Health state valuation and diagnostic-therapeutic pathways at the junction between non-metastatic and metastatic castration-resistant prostate cancer (CRPC) are not well documented. We aimed at: (i) estimating the disability weights (DWs) for health states across a continuum of disease from asymptomatic non-metastatic (nmCRPC) to symptomatic metastatic state (mCRPC); (ii) mapping the diagnostic-therapeutic pathway of nmCRPC in Italy.

Methods: Structured qualitative interviews were performed with clinical experts to gather information on nmCRPC clinical pathway. An online survey was administered to clinical experts to estimate DWs for four CRPC health states defined from interviews and literature review (i.e., nmCRPC, asymptomatic mCRPC, symptomatic mCRPC, mCRPC in progression during or after chemotherapy). Clinicians' preferences for health states were elicited using the Person-Trade-Off (PTO) and Visual Analogue Scale (VAS) methods. DWs associated with each health state, from 0 (best imaginable health state) and 1 (worst imaginable health state), were estimated.

Results: We found that the management of nmCRPC is heterogeneous across Italian regions and hospitals, especially with respect to diagnostic imaging techniques. DWs for PTO ranged from 0.415 (95% confidence interval [CI] 0.208-0.623) in nmCRPC to 0.740 (95% CI 0.560-0.920) in mCRPC, in progression during or after chemotherapy. DWs for VAS ranged between 0.246 (95% CI 0.131-0.361) in nmCRPC to 0.689 (95% CI 0.583-0.795) in mCRPC, in progression during or after chemotherapy.

Conclusions: Estimated DWs suggest that delaying transition to a metastatic state might ease the disease burden at both patient and societal levels.
