Influence of biosimilar infliximab launch on the utilization pattern of biological medicines: the case of Hungary

Maximizing the benefits of using biosimilars in Egypt

BACKGROUND

Biosimilars constitute a pathway for sustainable financing of healthcare systems in the era of expensive biologics. However, such a pathway is not free of challenges. Since the biosimilars market is expanding in Egypt, there is an urgent need for a policy framework to optimize their use and diffusion in the market. We aim to characterize a national framework based on the experiences of other countries and consultation with local experts.

METHODS

A narrative literature review was conducted to identify biosimilars' policy elements worldwide. A workshop was organized with experts to discuss the narrative review findings and create consensus on recommendations.

RESULTS

The narrative literature review highlighted the need for biosimilar policy actions in four areas: market authorization, pricing, reimbursement, and uptake. Eighteen experts representing the Egyptian healthcare authorities attended the workshop. The most significant conclusions from the workshop included setting the price of the biosimilar at 30-40% less than its originator's price and establishing financing protocols, in which the more expensive biologics with significant price premiums should be excluded from the formulary.

CONCLUSIONS

A summarized national framework policy recommendation for biosimilars was created by local experts from the main public healthcare entities in Egypt. These recommendations coincide with the international policies adopted across different countries that aim to improve patient access while sustaining health expenditure.

Safety and Effectiveness of Multiple Switching Between Originators and Biosimilars: Literature Review and Status Report on Interchangeability

To date, numerous biosimilars are available in Europe and the practice of switching between originator and biosimilar or between two different biosimilars has become very widespread. However, multiple switching has not been adequately studied. The aim of this study is to conduct a literature review to assess the effectiveness and safety of multiple switches. All PubMed articles involving multiple switches from originator to biosimilars or between different biosimilars were considered. The relevant data on effectiveness and safety were extracted from these studies and the results were reported through descriptive analysis. Fifteen studies were considered, of which 11 were observational and 4 clinical trials. Inflammatory bowel disease and psoriasis were the most studied diseases. All studies reported that the effectiveness and safety in patients whose treatment involved multiple switches, was comparable to patients whose treatment involved a single or no switch at all. Some therapeutic fields such as oncology and renal insufficiency were not represented at all in the multiple switch studies. New evidence is desperately needed and should be made available to the scientific community and decision-makers.

Monitoring a Mandatory Nonmedical Switching Policy from Originator to Biosimilar Infliximab in Patients with Inflammatory Bowel Diseases: A Population-Based Cohort Study

Background

On September 5, 2019, British Columbia announced a new policy (the Biosimilars Initiative) to switch from originator to biosimilar infliximab for patients with inflammatory bowel diseases.

Objective

To monitor the impacts of the policy on the use of medications and health services during the first year of the policy.

Methods

In this population-based cohort study, we used administrative health data to construct three historical cohorts and one policy cohort of patients with inflammatory bowel diseases who used the originator infliximab. We then monitored the cumulative incidence of medications and health services. Log-likelihood ratios were used to quantify differences between the policy cohort and the average of the historical cohorts.

Results

The cohorts included 1839-2368 users of the originator infliximab, ages 4-90 years, mean age 43 years. During the first year of follow-up, we found: (1) a 0.9% increase in the first dispensation of infliximab, biosimilar, or originator; (2) a 16.2% increase in infliximab dose escalation; (3) a decrease of 2.4% in the dispensation of antibiotics and a 2.6% decrease in new use of prednison; (4) an anticipated increase in visits to physicians and gastroenterologists to manage switching to biosimilars (24.0%); (5) a 4.0% decrease in discharges from hospital; and (6) a 2.9% decrease in emergency admissions to hospital.

Conclusion

British Columbia's Biosimilars Initiative for nonmedical switching from originator to biosimilar infliximab for inflammatory bowel diseases was not associated with harmful impacts on medications and health services use. An increase in dose escalation was accompanied by an improvement in health status proxies.

Biosimilar development and review process in the BRICS-TM countries: proposal for a standardized model to improve regulatory performance

OBJECTIVES

The current study is aimed at proposing a standardized regulatory model for biosimilar development and approval for adoption by BRICS-TM agencies, based on evaluation of regulatory guidelines and potential solutions to challenges.

METHODS

An established validated questionnaire was used and the recommendations were collated. Propositions deemed critical for improving the regulatory pathway for biosimilar development were synthesized to design a new regulatory model.

RESULTS

The key areas for improvement in BRICS-TM countries were: effective implementation of a step-wise approach; adoption of science-based regulatory evaluation for clinical efficacy studies and acceptance of analytical comparability studies in lieu of confirmatory clinical trials; a streamlined biosimilar development program for RBP sourcing; regulatory reliance for joint or shared review of the applications; and enhanced transparency and communication between the regulatory agencies and biosimilar developers. Based on these identified critical aspects, a simplified and standard regulatory model was developed to enable standardization of biosimilar guidelines across BRICS-TM countries for a common development program.

CONCLUSIONS

Effective implementation of the proposed standardized model for biosimilar development and approval processes across the BRICS-TM agencies will eliminate unwarranted studies, reduce the development costs and enhance process efficiency thereby expediting patients' access to new affordable biosimilar medicines.

The Impact of Reimbursement Practices on the Pharmaceutical Market for Off-Patent Medicines in Slovakia

Background: The aim of this study was to investigate the impact of selected legislative initiatives and their implementation for off-patent medicinal products in Slovakia compared with the rest of the Visegrád Group (V4 countries).

Methods: We analyzed the development of applications for the reimbursement of generic and biosimilar drugs. Particular emphasis was placed on a) the availability and penetration of biosimilars from 2006 to 2020 in Slovakia, b) a comparative analysis of biosimilars in V4 countries based on the national reimbursement lists of medicinal products for August 2021. Data relating to the sales of generic and biosimilar medicines in Czechia, Hungary, Poland, and Slovakia were based on the IQVIA MIDAS MAT July 2021.

Results: The number of applications for the reimbursement of generic drugs decreased from 296 in 2016 to 165 in 2020. In financial terms, the sales of generic medicines in Slovakia increased from 21.7% in 2015 to 22.3% in 2020. Over the same period, the sales of generic drugs in Poland fell from 40.4% in 2015 to 35.0% in 2020, from 26.2 to 22.1% in Hungary, and from 29.6 to 20.4% in Czechia. When considering the 66 biosimilars registered by the European Medicines Agency 38 drugs (58%) were available on the Slovak market as of August 1, 2021; this compared to 32 drugs (48%) in Poland, 38 drugs (58%) in Hungary, and 40 drugs (61%) in Czechia. In financial terms, the sales of biosimilars in Slovakia increased from 0.94% in 2015 to 2.00% in 2020. Over the same period, the sales of biosimilars in Poland increased from 0.59% in 2015 to 1.29% in 2020, from 0.72 to 2.23% in Hungary, and from 0.76 to 2.15% in Czechia.

Conclusion: To intensify the use of generic and biosimilar medicines, we suggest the comprehensive re-evaluation of combinations of the three-threshold entry, the amount of mandatory price reductions, and external reference pricing requirements (as the average of the three lowest prices among the official prices of a medicinal product in other Member States) for generic and biosimilar drugs. We also suggest cancellation of the exception from the fixed co-payment of the insured.

Utilisation Trend of Long-Acting Insulin Analogues including Biosimilars across Europe: Findings and Implications

BACKGROUND

Diabetes mellitus rates and associated costs continue to rise across Europe enhancing health authority focus on its management. The risk of complications is enhanced by poor glycaemic control, with long-acting insulin analogues developed to reduce hypoglycaemia and improve patient convenience. There are concerns though with their considerably higher costs, but moderated by reductions in complications and associated costs. Biosimilars can help further reduce costs. However, to date, price reductions for biosimilar insulin glargine appear limited. In addition, the originator company has switched promotional efforts to more concentrated patented formulations to reduce the impact of biosimilars. There are also concerns with different devices between the manufacturers. As a result, there is a need to assess current utilisation rates for insulins, especially long-acting insulin analogues and biosimilars, and the rationale for patterns seen, among multiple European countries to provide future direction. Methodology. Health authority databases are examined to assess utilisation and expenditure patterns for insulins, including biosimilar insulin glargine. Explanations for patterns seen were provided by senior-level personnel.

RESULTS

Typically increasing use of long-acting insulin analogues across Europe including both Western and Central and Eastern European countries reflects perceived patient benefits despite higher prices. However, activities by the originator company to switch patients to more concentrated insulin glargine coupled with lowering prices towards biosimilars have limited biosimilar uptake, with biosimilars not currently launched in a minority of European countries. A number of activities were identified to address this. Enhancing the attractiveness of the biosimilar insulin market is essential to encourage other biosimilar manufacturers to enter the market as more long-acting insulin analogues lose their patents to benefit all key stakeholder groups.

CONCLUSIONS

There are concerns with the availability and use of insulin glargine biosimilars among European countries despite lower costs. This can be addressed.

How to solve financing gap to ensure patient access to patented pharmaceuticals in CEE countries? - the good, the bad, and the ugly ways

Introduction: There is significant difference in utilization of patented medicines in the EU, as pharmaceuticals at Western European price levels are usually not cost-effective in Central and Eastern European (CEE) countries. The article reviews options to solve the 'financing gap' posed by the challenge of covering patented medicines from more restricted resources in countries with greater unmet medical need.Areas covered: Hidden volume restrictions to patented pharmaceuticals implemented by payers to facilitate financial sustainability may increase European inequity in patient access. Confidential price discounts and financial risk-sharing agreements improve cost-effectiveness of pharmaceuticals with limited impact on the European floor price. Narrowing the eligible group of patients on the positive drug list can help to target the medicines to patients with potentially greater health benefit whilst reducing the budget impact. Pay-for-performance schemes can improve cost-effectiveness of pharmaceuticals with significant uncertainty or heterogeneity in the magnitude of added therapeutic value. Increased utilization of off-patent pharmaceuticals can increase patient access through re-investing the savings from generic or biosimilar price erosion.Expert opinion: Transparent and sustainable pharmaceutical policies aiming to improve the allocative efficiency of scarce resources should be implemented in CEE to reduce financing gap and improve patient access to high-cost medicines.
