Real world data in the era of Immune Checkpoint Inhibitors (ICIs): Increasing evidence and future applications in lung cancer.

Immune checkpoint inhibitors (ICIs) targeting programmed death 1 (PD-1) and PD-ligand 1 (PD-L1) quickly subverted the standard of treatment in Non-Small Cell Lung Cancer (NSCLC), where they were first introduced in all comers previously treated advanced/metastatic NSCLC patients and subsequently in the first line of PD-L1 selected cases of metastatic and locally advanced disease. Treatment algorithm is an evolving landscape, where the introduction of front-line ICIs, with or without chemotherapy, unavoidably influences the following treatment lines. In this context, medical oncologists are currently facing many unclear issues, which have been not clarified so far by available data. Effectiveness and safety in special populations underrepresented in clinical trials - such as elderly, poor PS, hepatitis or human immunodeficiency virus-affected patients - are only a part of the unexplored side of ICIs in the real world. Indeed, pivotal randomized clinical trials (RCTs) often lack of external validity because eligibility criteria exclude some patient subgroups commonly treated in real-world clinical practice. Similarly, cost-effectiveness and sustainability of these innovative agents are important issues to be considered in the real-world. Though affected by several limitations, real-world evidence (RWE) studies allow to collect data regarding overall treated patients in clinical practice according to local authority regulations, overcoming the intrinsic limits of RCTs. The present review focuses on RWE about ICIs in lung cancer treatment, with particular reference to special patient populations, and discusses potential application of real-world data in a potential innovative drug development model

Regional Formularies in Italy: current state and future perspectives

Regional Formularies in Italy: current state and future perspectives Regional Formularies (RF) are considered part of pharmaceutical policies implemented by regions to govern access of medicines to regional market. However, they have been actually challenged, because of their presumed impact on differences of patient's access across the regions. The paper aimed at investigating the current status of RF and Regional Therapeutic Committees (CTR) and at suggesting/recommending possible reforms. The current status was investigated through a questionnaire administered to the regional pharmaceutical departments. Recommendations were retrieved from a multi -stakeholder work group carried out on 30-31 March 2023, embedded into a Forum focused on the regional pharmaceutical policies. Nineteen out of twenty-one regions responded to the survey: 12 use RF, mainly managed by the CTR; the RF frequency of update and the time needed for drugs listing greatly vary across regions; pharmacists, specialists and general practitioners are always represented in CTR, whereas other healthcare professionals and experts are more rarely involved; in 3 regions the CTR does not publish any RF update; the CTR mainly rely, to take decisions, on the dimension of the target population, the cost of therapy compared to alternative treatments and the impact on pharmaceutical expenditure. The working group recommended to overcome the RFs, if they are merely considered a list of available drugs at regional level, focusing CTR activities to ensure market access and to govern the prescribing behaviour, and strengthening/anticipating the flow of information from the Italian Medicines Agency (AIFA) to the regions, to enable a more efficient approach to local access to drugs

Liver injury due to amoxicillin vs. amoxicillin/clavulanate: a subgroupnalysis of a drug-induced liver injury case-control study in Italy

Several studies showed that amoxicillin plus clavulanic acid (co-amoxiclav) is one of the most common agents associated to serious Drug Induced Liver Injury (DILI). We estimated the risk of acute serious DILI associated with amoxicillin alone compared with co-amoxiclav, through a multicenter case-control study carried out in nine Italian hospitals from October 2010 to January 2014.Cases were adults, with a diagnosis of acute liver injury. Controls presented acute clinical disorders, not related to chronic conditions and not involving the liver. Adjusted Odds Ratio (ORs) with 95% CI were calculated initially with a bivariate and then multivariate analysis. We analysed 179 cases matched to 1770 controls. Seven cases were exposed to amoxicillin (adjusted OR 1.69, 95% CI 0.72-3.98) and 22 cases to co-amoxiclav (adjusted OR 3.00, 95% CI 1.76-5.40). Co-amoxiclav almost doubled the risk of serious acute liver injury compared to amoxicillin alone. The incidence of co-amoxiclav induced DILI is very low but the widespread use of this drug by the general population makes the risk clinically relevant. The often inappropriate prescription of antimicrobial agents, and in particular of co-amoxiclav, could expose a given patient to a life-threatening risk compared to a negligible clinical benefit

Good practices for the development of budget impact models at regional level

Introduction: The present work aims to discuss the current scenario of procedures and regulations regarding budget impact analysis/models (BIA/BIM) at regional level in Italy and to provide a standardized approach and detailed recommendations for developing these analyses. Method: A systematic review of the literature was conducted in order to collect existing guidelines or specific regional procedures for budget impact analysis in Italy. All the records were analysed in qualitative terms according to a pre-specified analytical framework, based on the ISPOR BIA guidelines. At the end of the analysis, a consensus questionnaire was developed to establish agreed approaches and to provide possible solutions to any critical issues. A list of 39 statements was developed. The survey was distributed to 69 experts who rated their level of agreement with each statement on a 5-point Likert scale. Consensus was predefined as more than 66% of the panel agreeing/disagreeing with any given statement. Results: Sisty-nine experts answered the questionnaire; a total of 30/39 statements achieved consensus. There was agreement on most of the statements. Time horizon to consider and costs were the issues on which no agreement was found. The results allowed the working group to define a list of good practices. Conclusion: While the structure and development of BIM are now well-known and well-applied at national level, there remains a great diversity of management of BIM tools at regional level. Consensus was reached among participating experts, as to the main characteristics, determinants and features of regional BIA/BIM in the perspective of the Italian payer

Measuring Multi-Joint Stiffness during Single Movements: Numerical Validation of a Novel Time-Frequency Approach

This study presents and validates a Time-Frequency technique for measuring 2-dimensional multijoint arm stiffness throughout a single planar movement as well as during static posture. It is proposed as an alternative to current regressive methods which require numerous repetitions to obtain average stiffness on a small segment of the hand trajectory. The method is based on the analysis of the reassigned spectrogram of the arm's response to impulsive perturbations and can estimate arm stiffness on a trial-by-trial basis. Analytic and empirical methods are first derived and tested through modal analysis on synthetic data. The technique's accuracy and robustness are assessed by modeling the estimation of stiffness time profiles changing at different rates and affected by different noise levels. Our method obtains results comparable with two well-known regressive techniques. We also test how the technique can identify the viscoelastic component of non-linear and higher than second order systems with a non-parametrical approach. The technique proposed here is very impervious to noise and can be used easily for both postural and movement tasks. Estimations of stiffness profiles are possible with only one perturbation, making our method a useful tool for estimating limb stiffness during motor learning and adaptation tasks, and for understanding the modulation of stiffness in individuals with neurodegenerative diseases

Clinical pathways in gastric cancer care

The diagnostic–therapeutic pathways (DTPs) are emerging as useful instruments for clinical management of complex diseases as gastric cancer, whose treatment is challenging and requires a multidisciplinary approach. However, the DPTs of patients with gastric cancer are still not defined yet. The aim of this study was to define the optimal DPT to be applied for patients with gastric cancer in the Veneto region. Rather than defining the ideal DTPs a priori, we conducted a preliminary research by analyzing the differences in the actual DPTs for patients with gastric cancer among different hospitals (hub and spokes) in Veneto. Then, the final DPT was elaborated based on the current available best clinical evidences; however, also the areas of homogeneity among the actual DPTs of the included centers as well as the critical issues that had emerged by our preliminary analysis were taken into account for pathway design. High heterogeneity in actual DTPs of patients with gastric cancer was observed among the analyzed centres. Moreover, some of the major criticisms have been found at crucial points of the current pathways. Based on these data, a reference path that is applicable to the whole-regional health network was constructed. The reference DTP is focused on multidisciplinary team management of patients with gastric cancer. Clinical pathways are essential tools to properly manage complex diseases such as gastric cancer. As such, more efforts should be done to implement their use

Cost-effectiveness analysis of the new oncological drug durvalumab in Italian patients with stage III non-small cell lung cancer

Background The monoclonal antibody durvalumab, an immune-checkpoint inhibitor (ICI) antiprogrammed death ligand 1 (PD-L1), is available for unresectable stage III NSCLC patients as consolidation therapy following induction chemoradiotherapy, with very promising overall survival (OS) and progression-free survial (PFS) results in registration trials. The purpose of this study was to provide policymakers with an estimate of the cost-effectiveness of durvalumab in the treatment of non-small cell lung cancer (NSCLC). Methods The study developed a Markov model covering a 5-year period to compare costs and outcomes of treating PD-L1 positive patients with or without durvalumab. We conducted a series of sensitivity analyses (Tornado analysis and Monte Carlo simulation) by varying some parameters to assess the robustness of our model and identify the parameters with the greatest impact on cost-effectiveness. Results Prior to the release of durvalumab, the management of NSCLC over a 5-year period cost euro33 317 per patient, with an average life expectancy of 2.01 years. After the introduction of the drug, this increased to euro37 317 per patient, with an average life expectancy of 2.13 years. Treatment with durvalumab led to an incremental cost-effectiveness ratio (ICER) of euro35 526 per year. OS is the variable that contributes the most to the variability of the ICER. Conclusions The study observed that durvalumab is a cost-effective treatment option for patients with unresectable stage III NSCLC

Clinical performance indicators for monitoring the management of cutaneous melanoma: a population-based perspective

The prognosis of cutaneous malignant melanoma (CMM) is based on disease progression. The highly heterogeneous clinical-pathological characteristics of CMM necessitate standardized diagnostic and therapeutic interventions tailored to cancer's stage. This study utilizes clinical performance indicators to assess the quality of CMM care in Veneto (Northeast Italy). This population-based study focuses on all incidences of CMMs registered by the Veneto Cancer Registry in 2015 (1279 patients) and 2017 (1368 patients). An interdisciplinary panel of experts formulated a set of quality-monitoring indicators for diagnostic, therapeutic, and end-of-life clinical interventions for CMM. The quality of clinical care for patients was assessed by comparing the reference thresholds established by experts to the actual values obtained in clinical practice. The prevalence of stage I-CMM decreased significantly from 2015 to 2017 (from 71.8 to 62.4%; P < 0.001), and almost all the pathology reports mentioned the number of nodes dissected during a lymphadenectomy. More than 90% of advanced CMMs were promptly tested for molecular BRAF status, but the proportion of patients given targeted therapies fell short of the desired threshold (61.1%). The proportion of stage I-IIA CMM patients who inappropriately underwent computerized tomography/MRI/PET dropped from 17.4 to 3.3% ( P < 0.001). Less than 2% of patients received medical or surgical anticancer therapies in the month preceding their death. In the investigated regional context, CMM care exhibited both strengths and weaknesses. The evaluated clinical indicators shed essential insight on the clinical procedures requiring corrective action. It is crucial to monitor clinical care indicators to improve care for cancer patients and promote the sustainability of the healthcare system

Estimated direct costs of non-small cell lung cancer by stage at diagnosis and disease management phase: A whole-disease model

Background Non-small cell lung cancer (NSCLC) is the first cause of cancer-related death among men and the second among women worldwide. It also poses an economic threat to the sustainability of healthcare services. This study estimated the direct costs of care for patients with NSCLC by stage at diagnosis, and management phase of pathway recommended in local and international guidelines.Methods Based on the most up-to-date guidelines, we developed a very detailed "whole-disease" model listing the probabilities of all potentially necessary diagnostic and therapeutic actions involved in the management of each stage of NSCLC. We assigned a cost to each procedure, and obtained an estimate of the total and average per-patient costs of each stage of the disease and phase of its management.Results The mean expected cost of a patient with NSCLC is 21,328 euro (95% C.I. -20 897-22 322). This cost is 16 291 euro in stage I, 19530 euro in stage II, 21938 euro in stage III, 22175 euro in stage IV, and 28 711 euro for a Pancoast tumor. In the early stages of the disease, the main cost is incurred by surgery, whereas in the more advanced stages radiotherapy, medical therapy, treatment for progressions, and supportive care become variously more important.Conclusions An estimation of the direct costs of care for NSCLC is fundamental in order to predict the burden of new oncological therapies and treatments on healthcare services, and thus orient the decisions of policy-makers regarding the allocation of resources.Key pointsSignificant findings of the study The high costs of surgery make the early stages of the disease no less expensive than the advanced stages.What this study adds An estimation of the direct costs of care is fundamental in order to orient the decisions of policy-makers regarding the allocation of resources
