The European Commission (EC) has proposed to redefine 'unmet medical need' to steer pharmaceutical innovation and link the definition to incentives and regulatory tools and procedures. A multistakeholder meeting of the Regulatory Science Network Netherlands (RSNN) discussed the impact of this proposal. Four principles were highlighted (flexibility, feasibility, fairness, and sensitivity to risk) that were not considered sufficiently addressed.

Objective: To construct a framework and calculation tool to compare the consequences of implementing different payment models for high-cost, one-off potentially curative therapies and enable decision making to ultimately enhance timely patient access to innovative health interventions.

Methods: A framework outlining steps to determine potentially suitable payment models was developed. Based on the framework, a supporting calculation tool operationalised as an Excel-based model was constructed to quantify the associated costs for an average patient during the timeframe of the intended payment agreement, the total budget impact and associated benefits expressed in quality-adjusted life-years for the total expected lifetime of the patient population.

Article Synopsis
  • - The study assesses various managed entry agreements for financing the gene therapy atidarsagene autotemcel (Libmeldy) in the Dutch healthcare system, aiming to inform future payment structures for high-cost treatments.
  • - Three payment models were compared: a 60% price discount, outcome-based payments with discounts, and a willingness-to-pay linked model, focusing on costs and benefits for different patient response scenarios.
  • - Results indicated that outcome-based models generally led to lower budget impacts and better financial management for payers, especially for patients responding as predicted by health assessments, compared to a simple discount approach.

Operationalization guidance is needed to support health technology assessment (HTA) bodies considering implementing lifecycle HTA (LC-HTA) approaches. The 2022 Health Technology Assessment International (HTAi) Global Policy Forum (GPF) established a Task Force to develop a position paper on LC-HTA. In its first paper, the Task Force established a definition and framework for LC-HTA in order to tailor it to specific decision problems.

The 2022 Health Technology Assessment International (HTAi) Global Policy Forum (GPF) established the goal of developing a position statement and framework for lifecycle HTA (LC-HTA), through a Task Force leveraging multi-stakeholder monthly discussions and GPF member input. The Task Force developed a working definition: LC-HTA is a systematic process utilizing sequential HTA activities to inform decision making where the evidence base, the health technology itself, or the context in which it is applied, has a potential to meaningfully change at different points in its LC. Four key scenarios were identified where it was considered that an LC-HTA approach would add sufficient value to HTA bodies and their key stakeholders to justify the additional resource burden.

The European Medicines Agency (EMA) and European national/regional health technology assessment (HTA) organizations consider the availability of existing treatments when evaluating a new drug. Since disagreement about the availability of alternative treatments may impact patient access to new drugs, this study aimed to investigate whether the EMA and HTA organizations agreed on the availability of alternative treatments and whether a lack of alternative treatments was associated with HTA organizations' added benefit assessment outcomes. For 97 innovative drugs authorized in 2019-2021 (excluding vaccines and diagnostic tools), assessments by the EMA and AEMPS (Spain), AIFA (Italy), HAS (France), IQWiG/G-BA (Germany), NICE (England and Wales), and ZIN (the Netherlands) were identified.

This literature review had two objectives: to identify models for predicting the risk of coronary heart diseases in patients with diabetes (DM); and to assess model quality in terms of risk of bias (RoB) and applicability for the purpose of health technology assessment (HTA). We undertook a targeted review of journal articles published in English, Dutch, Chinese, or Spanish in 5 databases from 1st January 2016 to 18th December 2022, and searched three systematic reviews for the models published after 2012. We used PROBAST (Prediction model Risk Of Bias Assessment Tool) to assess RoB, and used findings from Betts et al.

Introduction: The uptake of complex technologies and platforms has resulted in several challenges in the pricing and reimbursement of innovative pharmaceuticals. To address these challenges, plenty of concepts have already been described in the scientific literature about innovative value judgment or payment models, which are either (1) remaining theoretical; or (2) applied only in pilots with limited impact on patient access; or (3) applied so heterogeneously in many different countries that it prevents the health care industry from meeting expectations of HTA bodies and health care payers in the evidence requirements or offerings in different jurisdictions.

Areas Covered: This paper provides perspectives on how to reduce the heterogeneity of pharmaceutical payment models across European countries in five areas, including 1) extended evaluation frameworks, 2) performance-based risk-sharing agreements, 3) pooled procurement for low volume or urgent technologies, 4) alternative access schemes, and 5) delayed payment models for technologies with high upfront costs.

Objectives: Uncertainty is a fundamental component of decision making regarding access to and pricing and reimbursement of drugs. The context-specific interpretation and mitigation of uncertainty remain major challenges for decision makers. Following the 2021 HTAi Global Policy Forum, a cross-sectoral, interdisciplinary HTAi-DIA Working Group (WG) was initiated to develop guidance to support stakeholder deliberation on the systematic identification and mitigation of uncertainties in the regulatory-HTA interface.

Article Synopsis
  • - The study examined the alignment and differences between health technology assessment (HTA) reports and clinical guidelines (CGs) for multiple sclerosis (MS) treatments across various European countries, finding that 90% of recommendations were similar but differed in treatment lines and subindications.
  • - Analysis included 132 HTA reports and 9 CGs for 16 MS medications approved between 1995 and 2020, revealing that while HTA reports frequently referenced CGs and clinician input, not all new HTA recommendations were incorporated into CGs.
  • - The authors suggest that increased dialogue among stakeholders and consultation of each other's documents could enhance the consistency and transparency of treatment recommendations, ultimately improving patient access to care.

Outcome-based reimbursement models can effectively reduce the financial risk to health care payers in cases when there is important uncertainty or heterogeneity regarding the clinical value of health technologies. Still, health care payers in lower income countries rely mainly on financial based agreements to manage uncertainties associated with new therapies. We performed a survey, an exploratory literature review and an iterative brainstorming in parallel about potential barriers and solutions to outcome-based agreements in Central and Eastern Europe (CEE) and in the Middle East (ME).

Introduction: Drug reimbursement decisions are often made based on a price set by the manufacturer. In some cases, this price leads to public and scientific debates about whether its level can be justified in relation to its costs, including those related to research and development (R&D) and manufacturing. Such considerations could enter the decision process in collectively financed health care systems.
