Prices, Costs, and Affordability of New Medicines for Hepatitis C in 30 Countries: An Economic Analysis

The evolution of health services research in Austria: a bibliometric exploration of trends, themes, and collaborations

Background

Health services research (HSR) in Austria has expanded rapidly over the past two decades, reflecting the evolving need for a healthcare system that effectively addresses the broader challenges of an increasingly strained healthcare environment. Mapping the progression and focus areas of this research is essential for guiding policy-making and future studies.

Objectives

This bibliometric study aims to chart the evolution of Austrian HSR between 2000 and 2024. By examining publication trends, thematic priorities, collaboration networks, and research impacts, the analysis provides evidence-based insights that inform healthcare strategies and highlight research gaps.

Methods

A systematic literature search was conducted in PubMed, which targeted peer-reviewed articles published from 2000-July 31, 2024. In total, 81 articles met the inclusion criteria. Bibliometric methods, including coauthorship mapping, keyword co-occurrence analysis, and citation tracking, were used to identify core research themes, key authors, and institutional collaborations.

Results

Annual publication outputs increased notably from 2019 to 2020, corresponding to the heightened focus on healthcare during the COVID-19 pandemic. The major themes included mental health, patient care, public health, and disease management, with a growing interest in telemedicine and digital solutions. The Medical University of Vienna led publication activity, and strong international ties were evident, particularly with institutions in the UK and Germany. Citation analyses revealed varied research impacts, with some highly cited studies influencing policy debates and clinical practices.

Conclusions

Austrian HSR has a dynamic trajectory, reflecting evolving national priorities and global healthcare challenges. Continued efforts are needed to address gaps involving underserved populations, integrate digital health technologies, and enhance economic evaluations of primary care reforms. Furthermore, better standardization in the reporting of funding sources and conflicts of interest is recommended to strengthen methodological rigor and public trust. By fostering collaboration, transparency, and comprehensive evaluations, HSR can more effectively shape equitable healthcare policies in Austria.

States, global power and access to medicines: a comparative case study of China, India and the United States, 2000-2019

BACKGROUND

What constitutes state`s global power to shape access to medicines? How was it distributed between states and how did this change from 2000 to 2019? In this comparative case study, we explored the powers of China, India and the United States, and discuss whether our findings from the pre-pandemic era were reflected in the global COVID-19 response related to pharmaceuticals. We used an analytical framework from the international relations literature on structural power, and assessed the following power structures after adapting them to the context of access to medicines: finance, production, financial protection, knowledge, trade and official development assistance.

RESULTS

We found that from 2000 to 2019 there had been a power-shift towards China and India in terms of finance and production of pharmaceuticals, and that in particular China had increased its powers regarding knowledge and financial protection and reimbursement. The United States remained powerful in terms of finance and knowledge. The data on trade and official development assistance indicate an increasingly powerful China also within these structures. During the COVID-19 pandemic, we found that the patterns from previous decades were continued in terms of cutting-edge innovation coming out of the United States. Trade restrictions from the United States and India contrasted our findings as well as the limited effective aid from the United States. Building on our findings on structural powers, we argue that both structural power and political decisions shaped access to medical technologies during the COVID-19 pandemic. We also examined the roles and positions of the three states regarding developments in global health governance on the COVAX mechanism, the TRIPS Agreement waiver and the pandemic accord in this context.

CONCLUSION

From 2000-2019, China and India increased their structural powers to shape global access to medical technologies. The recent COVID-19 pandemic demonstrated that both structural power and political decisions shaped global access to COVID-19 technologies.

Reforming the innovation system to deliver affordable medicines: a conceptual framework of pharmaceutical innovation as a complex adaptive system (forest) and theory of change

Background

The current mainstream pharmaceutical innovation system (PIS) is driven by the market-based logic of charging the highest prices societies will bear. Outcomes include unaffordable medicines, restricted access and pressure on health budgets. How can the innovation system change to deliver fairly-priced medicines?

Methods

We inductively developed a novel conceptual framework of the PIS as a complex adaptive system (CAS) analogous to a forest. We constructed a database of 140 pharmaceutical innovation initiatives that sought to address global public interest objectives such as fair pricing or missing innovation. We found a critical mass of initiatives clustered around four areas: pandemic preparedness, neglected diseases, rare diseases and antibiotics, which we conceptualised as niches within the ecosystem. We reviewed the literature on how each niche had emerged and evolved, conducted interviews, and organised workshops with experts on each niche. Finally, we identified from the literature an initial list of 'levers' of change in the PIS, supplemented them with additional levers found in each niche, then compared across niches.

Results

We found that actors created niches in the broader system by purposefully problematising an issue, then pulling on one or more of three levers: mobilising new resources, changing the roles of or creating new actors, and/or changing societal norms or legal rules. A wide range of actors - including governments, funders, R&D practitioners, or civil society groups - could pull these levers, and the order in which they were pulled was not fixed, consistent with a CAS.

Conclusions

Parts of the vast pharmaceutical innovation system have changed to deliver more affordable medicines by design. Such change has occurred largely within specialised niches, responding to evolving societal norms about the purpose of pharmaceutical innovation. Actors can achieve larger-scale change by further expanding and/or solidifying these niches through changes to resources, actor roles, norms and rules.

High prevalence of hepatitis C virus among criminals in rehabilitation facilities in Japan

OBJECTIVE

There is a high prevalence of hepatitis C virus (HCV) carriers in prison in several developed countries, but the situation in Japan has not been well reported. This study aimed to determine the state of HCV infection among criminals in Japan.

METHODS

We enrolled 533 criminals in rehabilitation facilities (354 men and 179 women) who underwent a medical check-up from April 2014 to March 2022. Their records of blood tests, medical history, and drug injection use were retrospectively analyzed.

RESULTS

The HCV-antibody positive rate was 11.1 % (59/533), with rates of 8.2 % (29/354) in men and 16.8 % (30/179 in women. Approximately half of the HCV-infected residents had a history of drug injection, and this rate did not vary by age or by sex. Although an opportunity to treat HCV infection with medical assistance from government was provided to all residents who were positive for HCV RNA, 26.5 % of them abandoned the treatment.

CONCLUSION

In spite of the generous economical support to treat HCV infection by the government and the free access system in Japan, eliminating HCV in criminals appears to be difficult. The reason for this problem might be the criminals' negligent attitude to life.

IFNL4 genotype and other personal characteristics to predict response to 8-week sofosbuvir-based treatment for chronic hepatitis C

BACKGROUND

Shorter duration therapy for hepatitis C virus (HCV) infection might reduce treatment costs and increase the number of patients treated and cured. We determined factors associated with treatment response after an 8-week sofosbuvir-based therapy and developed a simple model to predict an individual's likelihood of treatment success.

METHODS

Among 2907 patients who received ledipasvir/sofosbuvir for 8 weeks, we determined failure rates by demographic and clinical characteristics, and IFNL4-∆G/TT genotype. We estimated the average IFNL4 genotype-related treatment failure rate in major ancestry groups by applying our IFNL4 genotype results to genotype distributions from reference populations. We created a treatment response model based on three personal characteristics.

RESULTS

Overall, 4.4% of the patients failed treatment. We observed significantly lower failure rates for persons <50 years (1.6%), females (2.6%), those carrying the IFNL4-TT/TT genotype (1.8%), those with HCV RNA <5.8 log10 copies/mL (2.0%) or HCV genotype-1B infection (2.6%). In a model based on ancestry, age and sex, the predicted probability of treatment failure ranged from 0.5% among females of East Asian ancestry <50 years of age to 8.5% among males of African ancestry age ≥65 years.

CONCLUSION

Applying this algorithm at the point-of-care might facilitate HCV elimination, especially in low- and middle-income countries.

Low- And Middle-Income Countries Experienced Delays Accessing New Essential Medicines, 1982-2024

Little is known about how long it takes for new medicines to reach countries with different income levels. We analyzed data, sourced from IQVIA, on the timing of new drug launches in seventy-five low-, middle-, and high-income markets from 1982 to 2024. The sample captured the majority of essential medicines (as designated by the World Health Organization in the twenty-third Model List of Essential Medicines) that first came into medical use anywhere globally from 1982 onward. Kaplan-Meier estimates were used to quantify delays in launches across countries. Our analysis comprised 119 medicines with 6,871 observed launches. Nearly three-quarters (74 percent) of first launches occurred in just eight countries (in order of the most first launches, the US, the Netherlands, Sweden, Switzerland, the United Kingdom, France, Germany, and Japan). From the first launch globally, the median time to availability was 2.7 years for high-income countries, 4.5 years for upper-middle-income countries, 6.9 years for lower-middle-income countries, and 8.0 years for low-income countries. The gap between richer (high- and upper-middle-income) and poorer (lower-middle- and low-income) countries remained largely unchanged over time. Strategies to address the disparities highlighted by this analysis are urgently needed.

A Review on cLF36, a Novel Recombinant Antimicrobial Peptide-Derived Camel Lactoferrin

Lactoferrin is an antimicrobial peptide (AMP) playing a pivotal role in numerous biological processes. The primary antimicrobial efficacy of lactoferrin is associated with its N-terminal end, which contains various peptides, such as lactoferricin and lactoferrampin. In this context, our research team has developed a refined chimeric 42-mer peptide known as cLF36 over the past few years. This peptide encompasses the complete amino acid sequence of camel lactoferrampin and partial amino acid sequence of lactoferricin. The peptide's activity against human, avian, and plant bacterial pathogens has been assessed using different biological platforms, including prokaryotic (P170 and pET) and eukaryotic (HEK293) expression systems. The peptide positively influenced the growth performance and intestinal morphology of chickens challenged with pathogen bacteria. Computational methods and in vitro studies showed the peptide's antiviral effects against hepatitis C virus, influenza virus, and rotavirus. The chimeric peptide exhibited higher activity against certain tumor cell lines compared to normal cells, which may be attributed to the peptide's interaction with negatively charged glycosaminoglycans on the surface of tumor cells. Importantly, this peptide exhibited no toxicity against host cells and demonstrated remarkable thermal and protease stability in serum. In conclusion, while our investigations suggest that the chimeric peptide, cLF36, may offer potential as a candidate or complementary option to some available antibiotics, antiviral agents, and chemical pesticides, significant uncertainties remain regarding its cost-effectiveness, as well as its pharmacodynamic and pharmacokinetic characteristics, which require further elucidation.

Pricing, Procurement and Reimbursement Policies for Incentivizing Market Entry of Novel Antibiotics and Diagnostics: Learnings from 10 Countries Globally

BACKGROUND

Fostering market entry of novel antibiotics and enhanced use of diagnostics to improve the quality of antibiotic prescribing are avenues to tackle antimicrobial resistance (AMR), which is a major public health threat. Pricing, procurement and reimbursement policies may work as AMR 'pull incentives' to support these objectives. This paper studies pull incentives in pricing, procurement and reimbursement policies (e.g., additions to, modifications of, and exemptions from standard policies) for novel antibiotics, diagnostics and health products with a similar profile in 10 study countries. It also explores whether incentives for non-AMR health products could be transferred to AMR health products.

METHODS

This research included a review of policies in 10 G20 countries based on literature and unpublished documents, and the production of country fact sheets that were validated by country experts. Initial research was conducted in 2020 and updated in 2023.

RESULTS

Identified pull incentives in pricing policies include free pricing, higher prices at launch and price increases over time, managed-entry agreements, and waiving or reducing mandatory discounts. Incentives in procurement comprise value-based procurement, pooled procurement and models that delink prices from volumes (subscription-based schemes), whereas incentives in reimbursement include lower evidence requirements for inclusion in the reimbursement scheme, accelerated reimbursement processes, separate budgets that offer add-on funding, and adapted prescribing conditions.

CONCLUSIONS

While a few pull incentives have been piloted or implemented for antibiotics in recent years, these mechanisms have been mainly used to incentivize launch of certain non-AMR health products, such as orphan medicines. Given similarities in their product characteristics, transferability of some of these pull incentives appears to be possible; however, it would be essential to conduct impact assessments of these incentives. Trade-offs between incentives to foster market entry and thus potentially improve access and the financial sustainability for payers need to be addressed.

Still trouble with bleeding: Risk factors for HCV transmission in men who have sex with men and behavioural trajectories from 2019 to 2021

OBJECTIVES

To identify sexual/sex-associated risk factors for hepatitis C transmission among men who have sex with men (MSM) and visualise behavioural trajectories from 2019 to 2021.

METHODS

We linked a behavioural survey to a hepatitis C cohort study (NoCo), established in 2019 across six German HIV/hepatitis C virus (HCV) treatment centres, and performed a case-control analysis. Cases were MSM with recent HCV infection, and controls were matched for HIV status (model 1) or proportions of sexual partners with HIV (model 2). We conducted conditional univariable and multivariable regression analyses.

RESULTS

In all, 197 cases and 314 controls completed the baseline questionnaire and could be matched with clinical data. For regression models, we restricted cases to those with HCV diagnosed since 2018 (N = 100). Factors independently associated with case status included sex-associated rectal bleeding, shared fisting lubricant, anal douching, chemsex, intravenous and intracavernosal injections, with population-attributable fractions of 88% (model 1) and 85% (model 2). These factors remained stable over time among cases, while sexual partner numbers and group sex decreased during COVID-19 measures.

CONCLUSIONS

Sexual/sex-associated practices leading to blood exposure are key factors in HCV transmission in MSM. Public health interventions should emphasize the importance of blood safety in sexual encounters. Micro-elimination efforts were temporarily aided by reduced opportunities for sexual encounters during the COVID-19 pandemic.

Single domain antibodies from camelids in the treatment of microbial infections

Infectious diseases continue to pose significant global health challenges. In addition to the enduring burdens of ailments like malaria and HIV, the emergence of nosocomial outbreaks driven by antibiotic-resistant pathogens underscores the ongoing threats. Furthermore, recent infectious disease crises, exemplified by the Ebola and SARS-CoV-2 outbreaks, have intensified the pursuit of more effective and efficient diagnostic and therapeutic solutions. Among the promising options, antibodies have garnered significant attention due to their favorable structural characteristics and versatile applications. Notably, nanobodies (Nbs), the smallest functional single-domain antibodies of heavy-chain only antibodies produced by camelids, exhibit remarkable capabilities in stable antigen binding. They offer unique advantages such as ease of expression and modification and enhanced stability, as well as improved hydrophilicity compared to conventional antibody fragments (antigen-binding fragments (Fab) or single-chain variable fragments (scFv)) that can aggregate due to their low solubility. Nanobodies directly target antigen epitopes or can be engineered into multivalent Nbs and Nb-fusion proteins, expanding their therapeutic potential. This review is dedicated to charting the progress in Nb research, particularly those derived from camelids, and highlighting their diverse applications in treating infectious diseases, spanning both human and animal contexts.

Impacts of the Egyptian national screening and treatment programme for viral hepatitis C: A cost-effectiveness model

BACKGROUND & AIMS

Egypt used to have one of the highest prevalences of HCV infection worldwide. The Egyptian Ministry of Health launched a national campaign for the detection and management of HCV to reduce its burden. This study aims to carry out a cost-effectiveness analysis to evaluate the costs and benefits of the Egyptian national screening and treatment programme.

METHODS

A disease burden and economic impact model was populated with the Egyptian national screening and treatment programme data to assess direct medical costs, health effects measured in disability-adjusted life years and the incremental cost-effectiveness ratio. The scenario was compared to a historical base case, which assumed that no programme had been conducted.

RESULTS

Total number of viremic cases is expected to decrease in 2030 by 86% under the national screening and treatment programme, versus by 41% under the historical base case. Annual discounted direct medical costs are expected to decrease from $178 million in 2018 to $81 million by 2030 under the historical base case, while annual direct medical costs are estimated to have peaked in 2019 at $312 million before declining to $55 million by 2030 under the national screening and treatment programme. Under the programme, annual disability-adjusted life years are expected to decline to 127 647 by 2030, leading to 883 333 cumulative disability-adjusted life years averted over 2018-2030.

CONCLUSIONS

The national screening and treatment programme is highly cost-effective by the year 2021, cost-saving by 2029 and expected to save about $35 million in direct costs and $4705 million in indirect costs by 2030.

Changing Epidemiological Patterns of Infection and Mortality Due to Hepatitis C Virus in Poland

INTRODUCTION

Limited information is available on trends in hepatitis C virus (HCV) infection, particularly in Central Europe. To address this knowledge gap, we analyzed HCV epidemiology in Poland, considering socio-demographic characteristics, changing patterns over time, and the impact of the COVID-19 pandemic.

MATERIAL AND METHODS

We examined HCV cases (diagnosis and deaths) reported by national registries and used joinpoint analysis to estimate time trajectories.

RESULTS

Between 2009 and 2021, there were changes in the trends of HCV, shifting from positive to negative in Poland. Among men, there was a significant increase initially in diagnosis rate of HCV in rural areas (annual percent change, APC_2009-2016 +11.50%) and urban areas (APC_2009-2016 +11.44%) by 2016. In subsequent years until 2019, the trend changed direction, but the reduction was weak (P_trend > 0.05) in rural areas (-8.66%) and urban areas (-13.63%). During the COVID-19 pandemic, the diagnosis rate of HCV dramatically decreased in rural areas (APC_2019-2021 -41.47%) and urban areas (APC_2019-2021 -40.88%). Among women, changes in the diagnosis rate of HCV were less pronounced. In rural areas, there was a significant increase (APC_2009-2015 +20.53%) followed by no significant change, whereas changes occurred later in urban areas (APC_2017-2021 -33.58%). Trend changes in total mortality due to HCV were mainly among men, with a significant decrease in rural (-17.17%) and urban (-21.55%) areas from 2014/2015.

CONCLUSIONS

The COVID-19 pandemic reduced HCV diagnosis rates in Poland, especially for diagnosed cases. However, further monitoring of HCV trends is necessary, along with national screening programs and improved linkage to care.

Addressing Risks Derived From the Commodification of Substances of Human Origin: A European Proposal Applicable Worldwide

In view of the public consultation recently launched by the World Health Organization on Regulatory Convergence of Cell and Gene Therapy Products and the Proposal for a Regulation on substances of human origin (SoHO) repealing the European Union Directives on Blood and on Tissues and Cells, an opportunity arises to define an ethical and transparent framework of collaboration between industry and authorities responsible for SoHO-derived products, comprising medicines, medical devices, transfusion, and transplantation. The commodification of SoHO-derived medicinal products and medical devices entails important risks to the sustainability of healthcare systems and threatens the equitable access of patients to innovative therapies. It may also jeopardize the principle of altruistic donation of SoHO that is required for the treatment and survival of thousands of patients every year. This article puts forward several proposals aimed at reconciling the ethical principles of voluntary and unpaid SoHO donation and the noncommercialization of the human body with obtaining a profit that allows business activities, while ensuring high quality, safety, and efficacy standards of tissues and cells for clinical use.

The Cost-effectiveness of Transplanting Hearts From Hepatitis C-infected Donors Into Uninfected Recipients

BACKGROUND

The DONATE HCV trial demonstrated the safety and efficacy of transplanting hearts from hepatitis C viremic (HCV+) donors. In this report, we examine the cost-effectiveness and impact of universal HCV+ heart donor eligibility in the United States on transplant waitlist time and life expectancy.

METHODS

We developed a microsimulation model to compare 2 waitlist strategies for heart transplant candidates in 2018: (1) status quo (SQ) and (2) SQ plus HCV+ donors (SQ + HCV). From the DONATE HCV trial and published national datasets, we modeled mean age (53 years), male sex (75%), probabilities of waitlist mortality (0.01-0.10/month) and transplant (0.03-0.21/month) stratified by medical urgency, and posttransplant mortality (0.003-0.052/month). We assumed a 23% increase in transplant volume with SQ + HCV compared with SQ. Costs (2018 United States dollar) included waitlist care ($2200-190 000/month), transplant ($213 400), 4-wk HCV treatment ($26 000), and posttransplant care ($2500-11 300/month). We projected waitlist time, quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratios (ICERs [$/QALY, discounted 3%/year]; threshold ≤$100 000/QALY).

RESULTS

Compared with SQ, SQ + HCV decreased waitlist time from 8.7 to 6.7 months, increased undiscounted life expectancy from 8.9 to 9.2 QALYs, and increased discounted lifetime costs from $671 400/person to $690 000/person. Four-week HCV treatment comprised 0.5% of lifetime costs. The ICER of SQ + HCV compared with SQ was $74 100/QALY and remained ≤$100 000/QALY with up to 30% increases in transplant and posttransplant costs.

CONCLUSIONS

Transplanting hearts from HCV-infected donors could decrease waitlist times, increase life expectancy, and be cost-effective. These findings were robust within the context of current high HCV treatment costs.

Economic evaluation of the Hepatitis C virus elimination program in the country of Georgia, 2015 to 2017

BACKGROUND AND AIMS

In 2015, the country of Georgia launched an elimination program aiming to reduce the prevalence of Hepatitis C virus (HCV) infection by 90% from 5.4% prevalence (~150 000 people). During the first 2.5 years of the program, 770 832 people were screened, 48 575 were diagnosed with active HCV infection, and 41 483 patients were treated with direct-acting antiviral (DAA)-based regimens, with a >95% cure rate.

METHODS

We modelled the incremental cost-effectiveness ratio (ICER) of HCV screening, diagnosis and treatment between April 2015 and November 2017 compared to no treatment, in terms of cost per quality-adjusted life year (QALY) gained in 2017 US dollars, with a 3% discount rate over 25 years. We compared the ICER to willingness-to-pay (WTP) thresholds of US$4357 (GDP) and US$871 (opportunity cost) per QALY gained.

RESULTS

The average cost of screening, HCV viremia testing, and treatment per patient treated was $386 to the provider, $225 to the patient and $1042 for generic DAAs. At 3% discount, 0.57 QALYs were gained per patient treated. The ICER from the perspective of the provider including generic DAAs was $2285 per QALY gained, which is cost-effective at the $4357 WTP threshold, while if patient costs are included, it is just above the threshold at $4398/QALY. All other scenarios examined in sensitivity analyses remain cost-effective except for assuming a shorter time horizon to the end of 2025 or including the list price DAA cost. Reducing or excluding DAA costs reduced the ICER below the opportunity-cost WTP threshold.

CONCLUSIONS

The Georgian HCV elimination program provides valuable evidence that national programs for scaling up HCV screening and treatment for achieving HCV elimination can be cost-effective.

Evaluation of the implementation effect of hepatitis C medical insurance reimbursement policy in China: A RWS based on medical institutions

Objectives

To evaluate the implementation effect of hepatitis C medical insurance reimbursement policy in China from the view of medical institutions.

Methods

The electronic medical record of a top tertiary hospital in Chengdu from January 2014 to December 2020 were extracted, and the interrupted time series model was used to analyze the changes in diagnosis and treatment behavior and disease burden of hepatitis C patients after the implementation of HCV insurance reimbursement policy.

Results

In terms of diagnosis and treatment, the number of visits (β2 = 19.290, P < 0.001) and treatments (β2 = 14.291, P < 0.01) increased instantaneously after the implementation of the outpatient reimbursement policy in Chengdu in 2018, and there was no significant change after the implementation of the single line payment policy for oral direct antiviral (DAA) drugs in 2019 (P > 0.05); in terms of medical expenses, the total treatment cost (β2 = 21439.3, P < 0.001), out-of-pocket expenses (β2 = 6109.44, P < 0.001) and drug expenses (β2 = 21889.8, P < 0.001) of hepatitis C patients have been significantly reduced after the implementation of the single-line payment policy.

Conclusion

Hepatitis C medical insurance reimbursement policy can promote hepatitis C patients to actively seek medical treatment, promote the widespread use of DAA scheme, reduce the burden of patients, and improve the treatment efficiency of hepatitis C.

Valuation of Costs in Health Economics During Financial and Economic Crises: A Case Study from Lebanon

In 2019, we embarked on a study on the economic burden of multiple sclerosis (MS) in Lebanon, in collaboration with a premier Lebanese MS center. This coincided with a triple disaster in Lebanon, comprising the drastic economic and financial crisis, the COVID-19 pandemic, and the consequences of the explosion of Beirut's port. Specifically, the economic and financial turmoil made the valuation of costs challenging. Researchers could face similar challenges, particularly in low- and middle-income countries (LMICs) where economic crises and recessions are recurrent phenomena. This paper aims to discuss steps taken to overcome the fluctuation of the prices of resources to get a valid valuation of societal costs during times of a financial and economic crisis. In the absence of local costing data and guidelines for conducting cost-of-illness (COI) studies, this paper provides empirical recommendations on the valuation of costs that are particularly relevant in LMICs. We recommend (1) clear reporting and justification of the country-specific context, year of costing, assumptions, data sources, and valuation methods, as well as the indicators used to adjust cost for inflation during different periods of fluctuation of prices; (2) collecting prices of each resource from multiple and various sources; (3) conducting a sensitivity analysis; and (4) reporting costs in local currency and Purchasing Power Parity dollars (PPP$). Precision and transparency in reporting prices of resources and their sources are markers of the reliability of the COI studies.

Budget impact analysis of two treatment approaches for hepatitis C in Malaysia through the use of voluntary and compulsory licensing options

Introduction

A scaled-up treatment cascade with direct-acting antiviral (DAA) therapy is necessary to achieve global WHO targets for hepatitis C virus (HCV) elimination in Malaysia. Recently, limited access to sofosbuvir/daclatasvir (SOF/DAC) is available through compulsory licensing, with access to sofosbuvir/velpatasvir (SOF/VEL) expected through voluntary licensing due to recent agreements. SOF/VEL has superior clinical outcomes but has higher drug acquisition costs compared to SOF/DAC. A stratified treatment cascade might be the most cost-efficient approach for Malaysia whereby all HCV patients are treated with SOF/DAC except for patients with cirrhosis who are treated with SOF/VEL.

Methods

This study aimed to conduct a 5-year budget impact analysis of the proposed stratified treatment cascade for HCV treatment in Malaysia. A disease progression model that was developed based on model-predicted HCV epidemiology data was used for the analysis, where all HCV patients in scenario A were treated with SOF/DAC for all disease stages while in scenario B, SOF/DAC was used only for non-cirrhotic patients and SOF/VEL was used for the cirrhotic patients. Healthcare costs associated with DAA therapy and disease stage monitoring were included to estimate the downstream cost implications.

Results

The stratified treatment cascade with 109 in Scenario B was found to be cost-saving compared to Scenario A. The cumulative savings for the stratified treatment cascade was USD 1.4 million over 5 years.

Discussion

A stratified treatment cascade with SOF/VEL was expected to be cost-saving and can result in a budget impact reduction in overall healthcare expenditure in Malaysia.

Effectiveness and safety of generic and brand direct acting antivirals for treatment of chronic hepatitis C

BACKGROUND

Direct acting antivirals (DAAs) are a very effective treatment for hepatitis C virus (HCV). However, brand DAAs are expensive. The licensing of cheaper generic DAAs may address this issue, but there is a lack of clinical studies comparing the efficacy of generic vs brand DAA formulations.

AIM

To compare the efficacy and safety of generic against brand DAAs for chronic hepatitis C treatment in Bahrain.

METHODS

This was a retrospective observational study involving 289 patients with chronic HCV infection during 2016 to 2018. There were 149 patients who were treated with brand DAAs, while 140 patients were treated with generic DAAs. Commonly used DAAs were Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir ± Ribavirin, and Sofosbuvir/Daclatasvir ± Ribavirin. SVR at 12 wk post treatment was the main outcome variable.

RESULTS

Overall, 87 patients (30.1%) had cirrhosis and 68.2% had genotype 1 HCV infection. At 12 wk post treatment, SVR was achieved by 271 (93.8%) of the patients. In patients who were treated with generic medications, 134 (95.7%) achieved SVR at 12 wk post treatment, compared to 137 (91.9%) among those treated with brand medications (P = 0.19). Having cirrhosis [odds ratio (OR): 9.41, 95% confidence interval (CI): 2.47–35.84] and having HCV genotype 3 (OR: 3.56, 95%CI: 1.03–12.38) were significant independent predictors of not achieving SVR. Alanine transaminase, gamma-glutamyl transpeptidase, and total bilirubin levels decreased significantly following therapy with both generic and brand DAAs.

CONCLUSION

Generic and brand DAAs demonstrate comparable effectiveness in the treatment of chronic hepatitis C patients. Both are safe and equally effective in improving biochemical markers of hepatic inflammation.

Availability and affordability of cardiovascular medicines in a major city of Afghanistan in 2020

PURPOSE

Affordable access to quality medicines is a critical target of global efforts to achieve universal health coverage. The aim of this study is to measure the affordability and accessibility of cardiovascular medicines in the city of Herat, Afghanistan.

METHODS

The price, affordability, and availability data for 18 most sold generic (MSG) and lowest priced generic (LPG) products were collected from public and private pharmacies located in Herat city in Afghanistan in 2020, which in each area, six pharmacies were randomly selected from a combination of public and private ones based on the standardized methodology developed by WHO/HAI. According to this methodology on Medicine Prices, Accessibility, and Affordability, the minimum daily wage of an unskilled governmental worker, and the price of each type of cardiovascular medicines for one-month use were calculated separately. If the cost of the treatment was more than the minimum daily wage, the medicine was considered unaffordable.

RESULTS

The mean availability score for lowest price generic (LPG) in public and private pharmacies and based on the countries of origin including Iran, Pakistan, and India was 60%, 46%, and 31%, respectively. Of the 18 medicines surveyed, just Atenolol (Iranian brand) was found in all 30 pharmacies on the day of data collection. All Indian- brand medicines were less than fifty percent available in any of the surveyed public and private pharmacies. Among the medicines exported to Afghanistan, the population of Herat used more medicines made by Pakistan compared to India and Iran (MSG). Indian medicines were the most expensive ones and the Iranian medicines were the cheapest. A wage of less than one day was enough to afford one-month supply of generic medicines at the lowest price.

CONCLUSION

Access of patients to cardiovascular medicines in Afghanistan was 46% in this study which is regarded as low access. Most of available cardiovascular medicines in the market of this country were made in Iran, Pakistan and India. Although the Iranian ones were the cheapest, but people used more Pakistani medicines. LPG products were affordable to the studied population.

The reimbursement for expensive medicines: stakeholder perspectives on the SMA medicine nusinersen and the Dutch Coverage Lock policy

Background

The reimbursement for expensive medicines poses a growing challenge to healthcare worldwide. In order to increase its control over the costs of medicines, the Dutch government introduced the Coverage Lock (CL) policy in 2015. The CL postpones decisions regarding reimbursement of expensive medicines until detailed advice on i.e., cost-effectiveness has been given. The CL has been in place for six years, has raised many questions and concerns, but currently, no evaluation is known to the authors. A better understanding of the effects of the CL on all stakeholders involved may contribute to reflections on the CL process and help find ways to improve it. An evaluation of Dutch policy will also be relevant for other countries that aim to optimize reimbursement procedures for expensive treatments. To perform this evaluation, we focused on the CL procedure for the medicine nusinersen. Nusinersen is the first treatment for spinal muscular atrophy (SMA). Following EMA approval in May 2017, it was placed in the CL. The analysis of cost-effectiveness and added therapeutic value resulted in an advice for reimbursement limited to children younger than 9.5 years at the start of treatment; this was implemented from August 2018 onwards.

Methods

Qualitative stakeholder perspective analysis of the CL procedure focusing on nusinersen with 15 stakeholders.

Results

Stakeholders raised key issues of the CL based on their experience with nusinersen: emotional impact of the CL, duration of the CL procedure, appropriateness of the CL procedure for different types of medicines, transparency of the CL, a wish for patient-centred decision-making and the lack of uniformity of access to expensive treatments.

Discussion

Stakeholders supported measures to control healthcare expenses and to ensure reasonable pricing. They considered the delay in access to therapies and lack of procedural transparency to be the main challenges to the CL. Stakeholders also agreed that the interests of patients deserve more attention in the practical implementation of the reimbursement decision. Stakeholders suggested a number of adjustments to improve the CL, such as a faster start with conditional reimbursement programs to ensure access and intensify European collaboration to speed up the assessment of the medicine.

The ethics of aggregation in cost-effectiveness analysis or, "on books, bookshelves, and budget impact"

In deciding how to allocate resources, healthcare priority-setters are increasingly paying attention to an intervention's budget impact alongside its cost-effectiveness. Some argue that approaches that use budget impact as a substantive consideration unfairly disadvantage individuals who belong to large patient groups. Others reject such claims of "numerical discrimination" on the grounds that consideration of the full budget impact of an intervention's adoption is necessary to properly estimate opportunity cost. This paper summarizes this debate and advances a new argument against modifying the cost-effectiveness threshold used for decision-making based on a technology's anticipated budget impact. In making this argument, the paper sets out how the apparent link between budget impact and opportunity cost is largely broken if the effects of a technology's adoption are disaggregated, while highlighting that the theoretical aggregation of effects during cost-effectiveness analysis likely only poorly reflects the operation of the health system in practice. As such, it identifies a need for healthcare priority-setters to be cognizant of the ethical implications associated with aggregating the effects of a technology's adoption for the purpose of decision-making. Throughout the paper, these arguments are illustrated with reference to a "bookshelf" analogy borrowed from previous work.

Value of Triage Treatment Strategies to Distribute Hepatitis C Direct-Acting Antiviral Agents in an Integrated Healthcare System: A Cost-Effectiveness Analysis

OBJECTIVES

This study aimed to assess the cost-effectiveness of fibrosis-based direct-acting antiviral treatment policies for patients with chronic hepatitis C virus at the Kaiser Permanente Mid-Atlantic States health system.

METHODS

We used a Markov model to compare the lifetime costs and effects of treating patients with chronic hepatitis C virus at different stages of disease severity, or all stages simultaneously, based on a fibrosis score from the US healthcare sector perspective and societal perspective. The initial distribution of patients across fibrosis scores, the effectiveness of direct-acting antiviral therapy, and follow-up and monitoring protocols were specific to the Kaiser Permanente Mid-Atlantic States health system. Direct and indirect costs, transition probabilities, and utilities were derived from the literature. Deterministic and probabilistic sensitivity analyses were performed to assess the robustness of our results.

RESULTS

The "Treat All" option was dominant from both the societal and healthcare sector perspectives. The conclusion was robust in deterministic sensitivity analysis. The range of incremental costs between the less restrictive policies was small-the difference between the "Treat F1+" and the "Treat All" option was only $111 per person. Probabilistic sensitivity analyses showed, at both the $100 000/quality-adjusted life-year and $150 000/quality-adjusted life-year thresholds, there was a 70% chance that the "Treat All" option was more cost-effective than the "Treat F1+" option.

CONCLUSIONS

We found that expanded treatment access is cost-effective and, in many cases, cost saving. Although our results are primarily applicable to a regional integrated healthcare system, it offers some direction to any healthcare setting faced with resource constraints in the face of highly priced drugs.

Country versus pharmaceutical company interests for hepatitis C treatment

Hepatitis C virus (HCV) is one of the leading causes of liver disease and is responsible for massive health and economic burden worldwide. The disease is asymptomatic in its early stages, but it can progress over time to fatal end-stage liver disease. Thus, the majority of individuals infected with HCV are unaware of their chronic condition. Recent treatment options for HCV can completely cure the infection but are costly. We developed a game model between a pharmaceutical company (PC) and a country striving to maximize its citizens' utility. First, the PC determines the price of HCV treatment; then, the country responds with corresponding screening and treatment strategies. We employed an analytical framework to calculate the utility of the players for each selected strategy. Calibrated to detailed HCV data from Israel, we found that the PC will gain higher revenue by offering a quantity discount rather than using standard fixed pricing per treatment, by indirectly forcing the country to conduct more screening than it desired. By contrast, risk-sharing agreements, in which the country pays only for successful treatments are beneficial for the country. Our findings underscore that policy makers worldwide should prudently consider recent offers by PCs to increase screening either directly, via covering HCV screening, or indirectly, by providing discounts following a predetermined volume of sales. More broadly, our approach is applicable in other healthcare settings where screening is essential to determine treatment strategies.

What is the Out-of-Pocket Expenditure on Medicines in India? An Empirical Assessment using a Novel Methodology

The share of expenditure on medicines as part of the total out-of-pocket (OOP) expenditure on healthcare services has been reported to be much higher in India than in other countries. This study was conducted to ascertain the extent of this share of medicines expenditure using a novel methodology. OOP expenditure data were collected through exit-interviews with 5252 out-patient department (OPD) patients in three states of India. Follow-up interviews were conducted after day 1 and 15 of the baseline to identify any additional expenditure incurred. In addition, medicine prescription data were collected from the patients through prescription audits. Self-reported expenditure on medicines was compared with the amount imputed using local market prices based on prescription data. The results were also compared with the mean expenditure on medicines per spell of ailment among non-hospitalized cases from National Sample Survey (NSS) 75th round for the corresponding states and districts, which is based on household survey methodology. The share of medicines in OOP expenditure did not change significantly for organized private hospitals using patient-reported versus imputation-based method (30.74% to 29.61%). Large reductions were observed for single-doctor clinics, especially in case of Ayurvedic (64.51% to 36.51%) and Homeopathic (57.53% to 42.74%) practitioners. After adjustment for socio-demographic factors and types of ailments, we found that household data collection as per NSS methodology leads to an increase of 25% and 26% in reported share of medicines for public and private sector out-patient consultations respectively, as compared to facility based exit interviews with imputation of expenditure for medicines as per actual quantity and price data. The nature of health care transactions at single-doctor clinics in rural India leads to an over-reporting of expenditure on medicines by patients. While household surveys are valid to provide total expenditure, these are less likely to correctly estimate the share of medicines expenditure.

The Payer License Agreement, or "Netflix model," for hepatitis C virus therapies enables universal treatment access, lowers costs and incentivizes innovation and competition

BACKGROUND AND AIMS

High unit prices of treatments limit access. For epidemics like that of hepatitis C virus (HCV), reduced treatment access increases prevalence and incidence, making the infectious disease increasingly difficult to manage. The objective of the current study was to construct and test an alternative pricing model, the Payer License Agreement (PLA), and determine whether it could improve outcomes, cut costs and incentivize innovation versus the current unit-based pricing model.

METHODS

We built and used computational models of hepatitis C disease progression, treatment, and pricing in historical and future scenarios and quantitatively analyzed their economic and epidemiological impact in three high-income countries.

RESULTS

This study had three key results regarding HCV treatment. First, if the PLA model had been implemented when interferon-free direct-acting antiviral (DAA) combinations launched, the number of patients treated and cured would have more than doubled in the first three years, while the liver-related deaths (LRDs) would have decreased by around 40%. Second, if the PLA model had been implemented beginning in 2018, the year that several Netflix-like payment models were under implementation, the number of treated and cured patients would nearly double, and the LRDs would decline by more than 55%. Third, implementing the PLA model would result in a decline in total payer costs of more than 25%, with an increase to pharmaceutical manufacturer revenues of 10%. These results were true across the three healthcare landscapes studied, the USA, the UK and Italy, and were robust against variations to critical model parameters through sensitivity analysis.

CONCLUSIONS AND RELEVANCE

These results suggest that implementation of the PLA model in high-income countries across a variety of health system contexts would improve patient outcomes at lower payer cost with more stable revenue for pharmaceutical manufacturers. Health policy-makers in high-income countries should consider the PLA model for application to more cost-effective management of HCV, and explore its application for other infectious diseases with curative therapies available now or soon.

Should Hungary Pay More for a QALY Gain than Higher-Income Western European Countries?

OBJECTIVES

Cost-effectiveness thresholds (CETs) play a particularly important role in the reimbursement decisions of health technologies in countries with limited healthcare resources. Our goal is to develop a scientifically solid proposal for a revised cost-effectiveness threshold, as part of the planned review of the Hungarian health economic guidance.

METHODS

The Threshold Working Group of the Hungarian Health Economics Association performed a targeted review on CETs in European countries. International trends on CETs served as a basis for our recommendation, which was discussed at the Association's workshop and deliberated at an expert committee meeting with representatives from the national health technology assessment (HTA) and healthcare payer bodies, and academic HTA centres.

RESULTS

The current Hungarian CET is one of the highest among European countries relative to GDP per capita, and even higher in nominal value than the CET applied by NICE. As opposed to the current, single Hungarian threshold, other European countries apply multiple thresholds. The Working Group recommends that Hungary should also apply multiple CETs in the range of 1.5-3 times GDP per capita with stratification according to the relative quality-adjusted life-year (QALY) gain of the new technology. In addition, multiple CETs in the range of 3-10 times GDP per capita is recommended for technologies in rare diseases.

CONCLUSIONS

CETs should be aligned with the country's economic performance and should reflect societal preferences. Our recommendation may increase the efficiency of healthcare resource allocation in Hungary by strengthening the role of HTA in the reimbursement decisions and favouring new technologies with higher QALY gain.

"Ready for the future?" - Status of national and cross-country horizon scanning systems for medicines in European countries

Background: Horizon scanning aims to systematically identify upcoming health technologies and thus allows policy-makers to be better prepared for the entry of new medicines with possibly high price tags into the national health system. The aim of this study is to survey the existence of national and cross-national horizon scanning systems for medicines in European countries.

Methods: Experts working in public authorities (members of the Pharmaceutical Pricing and Reimbursement Information/PPRI network) in the WHO European region participated in surveys in 2014 and 2019 and informed about the status of horizon scanning in their country (response rate: 14 and 44 countries, respectively). Identified advanced horizon scanning systems as of 2019 were further investigated based on a literature review.

Results: In 2019, six countries (Iceland, Italy, the Netherlands, Norway, Sweden, United Kingdom) reported systematic use of horizon scanning for some new medicines, and four countries (Austria, Denmark, France, Ireland) had some horizon scanning activities ongoing. No systematic use of horizon scanning was reported from the remaining 34 countries. The findings of the survey undertaken five years earlier were similar, with even fewer systems in place. A recent development is the establishment of cross-country initiatives of governments that aim, among others, to jointly perform horizon scanning; the International Horizon Scanning Initiative (IHSI) initiated by the Beneluxa collaboration is the most advanced undertaking in this respect. Countries with systematic use tend to have horizon scanning fully integrated in a system for the management of new medicines, and they use horizon scanning outcomes to inform decisions as to whether or not a Health Technology Assessment will be conducted and price negotiations be started. Differences between existing horizon scanning systems mainly concern the timings of scanning and reporting, the sources for the inputs and the accessibility of the findings.

Conclusion: There appears to be a discrepancy between the perceived importance of horizon scanning based on some eye-opening examples in the past and its actual implementation in European health systems. The latter is likely attributable to horizon scanning being resource-intensive. The establishment of new national and international horizon scanning systems offers the opportunity to investigate their impact on sustainable access to affordable medicines from the start.

Adoption of new therapies in the treatment of Hepatitis: a verification of the accuracy of budget impact analysis to guide investment decisions

OBJECTIVES

While there are good Budget Impact Analysis (BIA) guidelines, studies still register potential bias. To do this, we compared the results between theoretical and real-world evidence (RWE) expenditures for medicines for Hepatitis C: boceprevir (BOC) and telaprevir (TVR). While both are not currently recommended in treatment guidelines following recent developments, this is an emblematic case because for 4 years these medicines consumed considerable resources.

METHODS

Theoretical results and RWE expenditures were compared regarding the incorporation of BOC and TVR in 2013-2014 into the Brazilian Public Health System. Theoretical values were extracted from Commission for Technology Incorporation Report and RWE expenditures were extracted from the administrative data records using deterministic-probabilistic linkage.

RESULTS

The estimated number of patients treated (BOC+TVR) was 13,012 versus 7,641 (real). The estimated purchase price for BOC was US$6.20 versus US$11.07 (real) and for TVR was US$42.21 versus US$84.09 (average/real). The estimated budget impact was US$285.16 million versus US$128.58 million (real).

CONCLUSION

This study demonstrates appreciable divergence (US$156.58 million) between the theoretical budget impact and RWE expenditures due to underestimated purchase prices and overestimated populations. The greater the degree of accuracy the more reliable and usable BIAs become for decision-making.

Barriers to scaling up hepatitis C treatment in Malaysia: a qualitative study with key stakeholders

Background

While the availability of generic direct-acting antivirals (DAAs) opens the door for large-scale treatment, the care for people living with hepatitis C virus (HCV) in Malaysia is shifting toward a tripartite partnership between the public health system, correctional settings and civil society organizations (CSOs). This study aimed to explore the barriers to scaling up HCV treatment in Malaysia from the perspective of key stakeholders.

Methods

Eighteen focus-group discussions (FGDs) were conducted with 180 individuals, who actively engaged in coordinating, executing or supporting the implementation of the national strategic plan for HCV. An analytical framework was adapted to guide the data collection and thematic analysis. It covered four key aspects of HCV treatment: geographical accessibility, availability, affordability and acceptability.

Results

Movement restrictions in times of coronavirus disease 2019 (COVID-19) outbreaks and being marginalized translated into barriers to treatment access in people living with HCV. Barriers to treatment initiation in health and correctional settings included limited staffing and capacity; disruption in material supply; silos mentality and unintegrated systems; logistical challenges for laboratory tests; and insufficient knowledge of care providers. Although no-cost health services were in place, concerns over transportation costs and productivity loss also continued to suppress the treatment uptake. Limited disease awareness, along with the disease-related stigma, further lowered the treatment acceptability.

Conclusions

This study disclosed a series of supply- and demand-side barriers to expanding the treatment coverage among people living with HCV in Malaysia. The findings call for strengthening inter-organizational collaborations to overcome the barriers.

Hepatitis C virus: A critical approach to who really needs treatment

Introduction of effective drugs in the treatment of hepatitis C virus (HCV) infection has prompted the World Health Organization to declare a global eradication target by 2030. Propositions have been made to screen the general population and treat all HCV carriers irrespective of the disease status. A year ago the new severe acute respiratory syndrome coronavirus 2 virus appeared causing a worldwide pandemic of coronavirus disease 2019 disease. Huge financial resources were redirected, and the pandemic became the first priority in every country. In this review, we examined the feasibility of the World Health Organization elimination program and the actual natural course of HCV infection. We also identified and analyzed certain comorbidity factors that may aggravate the progress of HCV and some marginalized subpopulations with characteristics favoring HCV dissemination. Alcohol consumption, HIV coinfection and the presence of components of metabolic syndrome including obesity, hyperuricemia and overt diabetes were comorbidities mostly responsible for increased liver-related morbidity and mortality of HCV. We also examined the significance of special subpopulations like people who inject drugs and males having sex with males. Finally, we proposed a different micro-elimination screening and treatment program that can be implemented in all countries irrespective of income. We suggest that screening and treatment of HCV carriers should be limited only in these particular groups.

Comparison of Prices and Affordability of Cancer Medicines in 16 Countries in Europe and Latin America

BACKGROUND

There are concerns that high prices of cancer medicines may limit patient access. Since information on prices for cancer medicines and their impact on affordability is lacking for several countries, particularly for lower income countries, this study surveys prices of originator cancer medicines in Europe and Latin America and assesses their affordability.

METHODS

For 19 cancer medicines, public procurement and ex-factory prices, as of 2017, were surveyed in five Latin American (LATAM) countries (Brazil, Chile, Colombia, Mexico, and Peru) and 11 European countries (Austria, France, Germany, Greece, Hungary, the Netherlands, Poland, Romania, Spain, Sweden, and the UK). Price data (public procurement prices in LATAM and ex-factory prices in Europe) in US dollar purchasing power parities (PPP) were analyzed per defined daily dose. Affordability was measured by setting medicines prices in relation to national minimum wages.

RESULTS

The prices of cancer medicines varied considerably between countries. In European countries with higher levels of income, PPP-adjusted prices tended to be lower than in European countries of lower income and LATAM countries. Except for one medicine, all surveyed medicines were considered unaffordable in most countries. In European countries of lower income and LATAM countries, more than 15 days' worth of minimum wages would be required by a worker to purchase one defined daily dose of several of the studied medicines.

CONCLUSIONS

The high prices and large unaffordability of cancer medicines call for strengthening pricing policies with the aim of ensuring affordable treatment in cancer care.

Pharmaceutical policies and regulations of oral antiviral drugs for treatment of hepatitis C in Egypt-case study

BACKGROUND

There are limited studies on the role of efficient regulatory mechanisms in facilitating greater access to Hepatitis C virus (HCV) treatment. Evidence to support the importance of effective pharmaceutical policies and regulations in improving access to oral viral drugs towards the elimination of HCV is needed. This study aims to explore the adequacy of the implemented pharmaceutical policies and regulations in Egypt and their role to improve the availability and affordability of direct-acting antivirals (DAAs) to achieve universal access to the treatment of HCV.

METHODS

The study adopts a qualitative methodology using desk review of regulatory and legislative information, literature review, and semi-structured interviews with key experts from the concerned governmental regulatory agencies, pharmaceutical industries, academic organizations, professional associations, civil society organizations, and clinicians who are working in researching treatments for hepatitis C.

FINDINGS

The common DAAs available in the market are Daclatasvir, Sofosbuvir, and Sofosbuvir-based direct-acting antiviral combinations. Fast-track medicines registration pathway for marketing authorization of DAAs is used to reduce market access time frames. The pricing policies are supplemented using price negotiation to set up affordable prices that led to a reasonable price for DAAs. Using Trade-Related Aspects of Intellectual Property Rights (TRIPs) flexibility and local production of quality generics DAAs at lower prices. In addition, political will and collaboration between the government, civil society, and pharmaceutical companies improved patients' access to affordable DAAs and succeeding hepatitis C treatment in Egypt.

CONCLUSIONS

The study findings indicated that the implemented pharmaceutical policies and regulations have an immense role in enhancing access to medicines towards the elimination of hepatitis C in Egypt.

Perioperative Management of Hepatitis C in Patients Undergoing Total Joint Arthroplasty

»

A small yet growing subset of total joint arthroplasty (TJA) candidates are diagnosed with the hepatitis C virus (HCV), which is a known risk factor for periprosthetic joint infections. Given the poor outcomes associated with TJA infection, we recommend that candidates with HCV receive treatment prior to elective TJA.

»

Interferon and ribavirin have historically been the standard treatment regimen for the management of HCV; however, adverse events and an inconsistent viral response have limited the efficacy of these therapies. The advent of direct-acting antivirals has resolved many of the issues associated with interferon and ribavirin regimens.

»

Despite the success of direct-acting antivirals, there are still barriers to seeking treatment for TJA candidates with HCV. Many patients are faced with financial burdens, as insurance coverage of direct-acting antiviral therapies is inconsistent and varies by the patient's state of residence and specific treatment regimen.

»

TJA candidates with HCV present health-care providers with a unique set of challenges, often encompassing economic, psychosocial, and complex medical concerns. Multidisciplinary care teams can be beneficial when caring for and optimizing this patient cohort.

»

Management of HCV prior to elective TJA is associated with higher up-front costs but ultimately reduces long-term patient morbidity as well as associated direct and indirect health-care expenditures.

Ethical Perspectives on Costly Drugs and Health Care

High drug prices have created substantial challenges for patients, physicians, health systems, and payers. High drug prices can affect patient care in many ways, including limiting access to treatment, increasing the burden of administrative tasks, and contributing to physician burnout. Exorbitant drug pricing poses direct challenges for distributive justice, which is concerned with fairly distributing benefits and burdens across society. In this position statement, we discuss ethical concerns raised by high drug costs, primarily focusing on concerns around distributive justice. We consider forms of rationing, approaches to allocation, potential complexities in real-life application, and structural forces contributing to high drug costs. Finally, we consider potential policy solutions and ramifications for individual clinicians.

Pharmaceutical drug development: high drug prices and the hidden role of public funding

In 2019, the record for the most expensive drug was broken at US$2.1 million per patient. The high costs of new drugs are justified by the pharmaceutical industry as the expense required for maintaining research and development (R&D) pipelines. However, this does not take into account that globally the public pays for between one to two-thirds of upfront R&D costs through taxpayers or charitable donations. Governments are effectively paying twice for medicines; first through R&D, and then paying the high prices upon approval. High drug prices distort research priorities, emphasising financial gains and not health gains. In this manuscript, issues surrounding the current patent-based drug development model, public funding of research and pharmaceutical lobbying will be addressed. Finally, innovations in drug development to improve public health needs and guaranteeing medication access to patients will be explored.

Improving healthcare for patients with HIV, tuberculosis and hepatitis C in eastern Europe: a review of current challenges and important next steps

OBJECTIVES

In some eastern European countries, serious challenges exist to meet the HIV-, tuberculosis (TB)- and hepatitis-related target of the United Nations Sustainable Development Goals. Some of the highest incidence rates for HIV and the highest proportion of multi-drug-resistant (MDR) tuberculosis worldwide are found in the region. The purpose of this article is to review the challenges and important next steps to improve healthcare for people living with TB, HIV and hepatitis C (HCV) in eastern Europe.

METHODS

References for this narrative review were identified through systematic searches of PubMed using pre-idientified key word for articles published in English from January 2000 to August 2020. After screening of titles and abstracts 37 articles were identified as relevant for this review. Thirty-eight further articles and sources were identified through searches in the authors' personal files and in Google Scholar.

RESULTS

Up to 50% of HIV/MDR-TB-coinfected individuals in the region die within 2 years of treatment initiation. Antiretroviral therapy (ART) coverage for people living with HIV (PLHIV) and the proportion virological suppressed are far below the UNAIDS 90% targets. In theory, access to various diagnostic tests and treatment of drug-resistant TB exists, but real-life data point towards inadequate testing and treatment. New treatments could provide elimination of viral HCV in high-risk populations but few countries have national programmes.

CONCLUSION

Some eastern European countries face serious challenges to achieve the sustainable development goal-related target of 3.3 by 2030, among others, to end the epidemics of AIDS and tuberculosis. Better integration of healthcare systems, standardization of health care, unrestricted substitution therapy for all people who inject drugs, widespread access to drug susceptibility testing, affordable medicines and a sufficiently sized, well-trained health workforce could address some of those challenges.

Considering potential solutions for limitations and challenges in the health economic evaluation of gene therapies

INTRODUCTION

The limited evidence in the clinical trials of gene therapies (GTs) posed substantial challenges for a reliable health technology assessment (HTA). This paper provides insights into the relationship between the background of diseases and the health economics assessment of GTs.Areas covered: The impacts of differentiated severity and unmet needs of genetic diseases, on the economic analysis of GTs, were discussed.Expert opinion: GTs offer a potential cure or significant clinical improvement, while limitations in clinical evidence constitute major obstacles for a robust assessment of clinical effectiveness and economic outcomes. This uncertainty may be balanced by the severity of the targeted condition and the associated unmet needs, thus leading to a relatively higher acceptance for GTs. Overtime, HTA agencies will become more demanding on comprehensive evidence of long-term effectiveness. With a growing number of GTs on the horizon, to what extent the unmet needs of previously devastating diseases will be fulfilled remain unclear. Nonetheless, comparative studies, either with a historical control group or existing treatments, will be necessary to demonstrate the additional benefits associated with GTs.

Improving access to the treatment of hepatitis C in low- and middle-income countries: evaluation of a patient assistance programme

Background Modern antiviral treatments have high cure rates against the hepatitis C virus however, the high cost associated with branded medicines and diagnostic tests, have resulted in poor access for many low-income patients residing in low-and-middle-income countries. Objective This study aimed to evaluate the role of a patient assistance programme and generic medicines in improving access to treatment of low-income hepatitis C patients in a low-and-middle-income country. Setting A major teaching public hospital in Islamabad, Pakistan. Methods Hepatitis C patients who presented and enrolled for the patient assistance programme during 12 months (1st July 2015 and 30th June 2016) were included. Demography, prescription characteristics, the total costs of Hepatitis C treatment, medicine cost supported by the programme, out-of-pocket cost borne by the patient and average cost effectiveness ratio per sustained virologic response were calculated and compared for different generic and branded regimens. Main outcome measure cost contribution of patient assistance programme. Results A total of 349 patients initiated the treatment through the programme and of those 334 (95.7%) completed the prescribed treatment. There were 294 (88.02%) patients who achieved sustained virologic response. Patient assistance programme contributed medicines cost averaging 60.28-86.26% of the total cost of treatment ($1634.6) per patient. The mean (SE) cost per patient for generic option (Sofosbuvir/Ribavirin) was the lowest [$658.36 (22.3) per patient, average cost effectiveness ratio = $720.1/SVR] than branded option (Sovaldi/Ribavirin) [$2218.66 (37.6) per patient, average cost effectiveness ratio = $2361.8/SVR] of the three available treatment regimens. From patients' perspectives, the mean (SE) out-of-pocket cost was $296.9 (6.7) which primarily included diagnostic cost (69.9%) of the total cost. Conclusions Patient assistance programme, combined with generic brands of newer hepatitis C treatment offered a significant reduction in cost and widens access to hepatitis C treatment in low-and middle-income countries. However, substantial out-of-pocket costs of the treatment presents an important barrier for service access. There is a scope to widen such financial assistance programme to offer other costs attributed to patients, specifically for diagnosis, to widen service use in low-and-middle-income countries.

Determinants of drug prices: a systematic review of comparison studies

OBJECTIVE

In this systematic review on drug price comparison studies, we report on recent determinants of drug prices in a national and international context to facilitate regulation of drug prices by purchasers and policymakers worldwide. Determinants of drug prices were divided into non-modifiable and modifiable and were categorised as pertaining to a country's income level, pharmaceutical market system and its policies and government.

PRIMARY OUTCOME

Determinants of drug prices or price variance.

DESIGN

We systematically searched PubMed, EMBASE, Web of Science and Cochrane Library for peer-reviewed articles published between 2004 and 22 July 2020 that reported an association of the primary outcome with one or more determinants. We performed a best-evidence synthesis of these associations for determinants covered in at least three studies.

RESULTS

31 publications were included. Only one publication described net drug prices and 30 described retail drug prices. Five modifiable determinants were associated with lower retail prices: generic market portion, discounts, tendering policies, central (governmental) purchasing and pricing regulation schemes. The originators market portion and a system in which mark-ups are common were associated with higher retail prices. Retail prices were highest in the USA, even compared with other high-income countries. A positive association between national income level and drug retail prices could not be established among middle-income and high-income countries. Retail prices were highest in low-income countries when adjusted for purchasing power parity.

CONCLUSIONS

Literature on determinants of net drug prices is extremely sparse. Various healthcare system interventions, market-specific and governmental regulations are consistently associated with lower retail prices. Some interventions are easily implementable in developing or middle-income countries, such as tendering, central purchasing and fixed pricing regulation schemes. Net drug price comparison studies are needed to overcome the lack of price transparency and to quantify the effectiveness of policy measures on net drug prices.

'Capacity for what? Capacity for whom?' A decolonial deconstruction of research capacity development practices in the Global South and a proposal for a value-centred approach

Whilst North to South knowledge transfer patterns have been extensively problematised by Southern and decolonial perspectives, there is very little reflection on the practice of research capacity development (RCD), still strongly focused on technoscientific solutionism, yet largely uncritical of its underlying normative directions and power asymmetries. Without making transparent these normative and epistemological dimensions, RCD practices will continue to perpetuate approaches that are likely to be narrow, technocratic and unreflexive of colonial legacies, thus failing to achieve the aims of RCD, namely, the equitable and development-oriented production of knowledge in low- and middle-income societies. Informed by the authors' direct experience of RCD approaches and combining insights from decolonial works and other perspectives from the margins with Science and Technology Studies, the paper undertakes a normative and epistemological deconstruction of RCD mainstream practice. Highlighting asymmetries of power and material resources in knowledge production, the paper's decolonial lens seeks to aid the planning, implementation and evaluation of RCD interventions. Principles of cognitive justice and epistemic pluralism, accessibility enabled by systems thinking and sustainability grounded on localisation are suggested as the building blocks for more reflexive and equitable policies that promote research capacity for the purpose of creating social value and not solely for the sake of perpetuating technoscience.

Liver targeting of ledipasvir via galactosylated chitosan-coated spanlastics: chemical synthesis, statistical optimization, in vitro, and pharmacokinetic evaluation

INTRODUCTION

Ledipasvir is an effective direct acting antiviral agent used in the treatment of hepatitis C virus. The high price of ledipasvir was a reason for its limited provision to wide population of HCV patients.

OBJECTIVES

Our objective is the formulation of liver targeted drug delivery system that can increase the amount of ledipasvir delivered to liver and prolong its liver residence in an attempt to reduce its recommended dose and its costing in the treatment of HCV.

METHODS

Different ledipasvir-loaded spanlastic formulations were prepared using the ethanol injection method and evaluated with respect to the particle size, zeta potential, polydispersity index, and entrapment efficiency %. Using Design-Expert ® software, the optimum spanlastics formulation was selected; then, it was coated by synthesized galactosylated chitosan. A pharmacokinetic study was carried out to evaluate the ability of the prepared galactosylated chitosan-coated spanlastics formulation to enhance ledipasvir liver bioavailability when it was administrated via the oral route.

RESULTS

The pharmacokinetic study revealed that the optimized galactosylated chitosan-coated spanlastics exhibited significantly higher liver peak concentration (Cmax) and area under liver concentration versus time curve (AUC0-72 h) and significant prolongation in the liver terminal half life (t½) and mean residence time (MRT) compared to the free ledipasvir dispersion with values of 6270 ng/g, 61,706.3 ng.h/g, 15.85 h, and 24.66 h, respectively.

CONCLUSIONS

Enhanced liver bioavailability of ledipasvir has been accomplished using the developed galactosylated chitosan-coated spanlastics which can be a base for probable reduction in the required dose of ledipasvir in HCV treatment.

Egypt's Ambitious Strategy to Eliminate Hepatitis C Virus: A Case Study

A national hepatitis C virus elimination strategy rooted in mass screening and treatment can be effective in many middle-income countries. A strong public health infrastructure, political commitment, and technological advances are essential to such initiatives.

Introduction:

Chronic hepatitis C virus (HCV) infection is a major public health problem in many low- and middle-income countries. In 2015, Egypt's HCV infection prevalence of 7% among adults was among the highest in the world and accounted for 7.6% of the country's mortality. In 2014, Egypt embarked on an aggressive screening and treatment program that evolved into a national strategy to eliminate HCV as a public health threat by 2021.

Methods:

In this qualitative case study, we analyzed Egypt's HCV control strategy using the Kingdon framework to understand how the problem, policy, and political streams merged to create an opportunity to achieve an ambitious elimination goal. We describe key aspects of the implementation, identify lessons learned, and provide recommendations for other low- and middle-income countries aiming to eliminate HCV.

Results:

Between 2014 and 2020, Egypt screened more than 50 million and treated more than 4 million residents for HCV. Five key elements contributed to Egypt's successful HCV elimination program: (1) sufficient and reliable epidemiologic data to quantify and monitor public health threats; (2) a robust public health care infrastructure; (3) inclusive care that reached all sectors of society; (4) political commitment to public health through increased health care spending and a comprehensive long-term national control strategy; and (5) innovative scientific research and use of information technology.

Conclusion:

Egypt conducted a successful HCV screening program that covered more than 50 million residents and treated more than 4 million. It is poised to be the first country in the world to eliminate HCV within its borders. The lessons learned from this experience can inform the elimination plans of other low- and middle-income countries with high HCV burden.

Affordability of Adult Tuberculosis Vaccination in India and China: A Dynamic Transmission Model-Based Analysis

New tuberculosis vaccines have made substantial progress in the development pipeline. Previous modelling suggests that adolescent/adult mass vaccination may cost-effectively contribute towards achieving global tuberculosis control goals. These analyses have not considered the budgetary feasibility of vaccine programmes. We estimate the maximum total cost that the public health sectors in India and China should expect to pay to introduce a M72/AS01_E-like vaccine deemed cost-effective at country-specific willingness to pay thresholds for cost-effectiveness. To estimate the total disability adjusted life years (DALYs) averted by the vaccination programme, we simulated a 50% efficacy vaccine providing 10-years of protection in post-infection populations between 2027 and 2050 in India and China using a dynamic transmission model of M. tuberculosis. We investigated two mass vaccination strategies, both delivered every 10-years achieving 70% coverage: Vaccinating adults and adolescents (age ≥10y), or only the most efficient 10-year age subgroup (defined as greatest DALYs averted per vaccine given). We used country-specific thresholds for cost-effectiveness to estimate the maximum total cost (C_max) a government should be willing to pay for each vaccination strategy. Adult/adolescent vaccination resulted in a C_max of $21 billion (uncertainty interval [UI]: 16–27) in India, and $15B (UI:12–29) in China at willingness to pay thresholds of $264/DALY averted and $3650/DALY averted, respectively. Vaccinating the highest efficiency age group (India: 50–59y; China: 60–69y) resulted in a C_max of $5B (UI:4–6) in India and $6B (UI:4–7) in China. Mass vaccination against tuberculosis of all adults and adolescents, deemed cost-effective, will likely impose a substantial budgetary burden. Targeted tuberculosis vaccination, deemed cost-effective, may represent a more affordable approach.

CD8+ T Cell Responses during HCV Infection and HCC

Chronic hepatitis C virus (cHCV) infection is a major global health burden and the leading cause of hepatocellular carcinoma (HCC) in the Western world. The course and outcome of HCV infection is centrally influenced by CD8⁺ T cell responses. Indeed, strong virus-specific CD8⁺ T cell responses are associated with spontaneous viral clearance while failure of these responses, e.g., caused by viral escape and T cell exhaustion, is associated with the development of chronic infection. Recently, heterogeneity within the exhausted HCV-specific CD8⁺ T cells has been observed with implications for immunotherapeutic approaches also for other diseases. In HCC, the presence of tumor-infiltrating and peripheral CD8⁺ T cell responses correlates with a favorable prognosis. Thus, tumor-associated and tumor-specific CD8⁺ T cells are considered suitable targets for immunotherapeutic strategies. Here, we review the current knowledge of CD8+ T cell responses in chronic HCV infection and HCC and their respective failure with the potential consequences for T cell-associated immunotherapeutic approaches.

Real-World Evidence: Bridging Gaps in Evidence to Guide Payer Decisions

Randomized controlled trials (RCTs) are preferred by payers for health technology assessments and coverage decisions. However, the inclusion of a highly selective patient population and the rigorously controlled conditions in RCTs may not be reflective of real-world clinical practice. Real-world evidence (RWE) obtained from an analysis of real-world data (RWD) from observational studies can bridge gaps in evidence not addressed by RCTs and is thus valuable to public and private payers for decision-making. Through a broad literature search to obtain insights into payers' experience, we found that payers have concerns about real-world studies with respect to data quality, poor internal validity, potential bias, and lack of meaningful endpoints. However, they valued RWE to fill evidence gaps not addressed by RCTs, such as high-quality, real-world, long-term effectiveness and safety data; head-to-head drug comparisons; cost analyses for tiering formulary placement; medication use and adherence patterns; identification of relevant responder and non-responder patient subpopulations; and patient-reported outcomes (PROs). RWE can be used to assess clinically meaningful endpoints and gauge the impact of interventions on the quality of healthcare. Here, we review how payers use or can use RWD on the comparative effectiveness and safety of treatments, PROs, medication adherence and persistence, prescribing patterns, healthcare resource utilization, and patient characteristics and/or biomarkers associated with treatment response when making health technology assessments and payer coverage decisions across therapeutic areas.

High rates of sustained virological response despite premature discontinuation of directly acting antivirals in HCV-infected patients treated in a real-life setting

In routine clinical practice, hepatitis C virus-infected patients can prematurely discontinue the prescribed regimen for several reasons. The aim of our study was to investigate sustained virological response (SVR12) rates in patients who prematurely discontinued directly acting antiviral (DAA) regimens and to assess the shortest effective duration of DAA able to lead to SVR12. We retrospectively collected the SVR rates of patients, registered in the NAVIGATORE-Lombardia Network database from January 2015, who discontinued DAAs before the predefined end of treatment. Overall, we included 365 patients, males were the majority (213, 58.4%), mean age was 60.5 years, and 53 (14.5%) patients were HIV-co-infected. Liver cirrhosis was observed in 251 (68.8%) subjects, and the most represented genotypes were 1b (n = 168, 46%) and 3 (n = 59, 16.2%). DAA was discontinued a median of 1 (IQR 1-4) weeks before the predefined EOT, with 164 (44.9%) patients stopping DAAs at least 2 weeks before the planned schedule. In patients with F0-F3 liver fibrosis, lower rates of SVR12 were observed in patients treated for <4 weeks: 50% (n = 2/4) vs. 99.1% (n = 109/110) for ≥4 weeks, p = 0.003. In patients with liver cirrhosis, lower rates of SVR12 were observed in patients treated <8 weeks: 83.3% (n = 25/30) vs. 94.6% (n = 209/221) for ≥8 weeks, p = 0.038. Despite premature discontinuation of DAA, high SVR12 rates were observed in a real-life setting for treatment lasting at least 4 weeks in patients with liver fibrosis F0-F3 and 8 weeks in those with liver cirrhosis. On this basis, feasibility of reducing DAA treatment duration should be explored in randomized clinical trials.
