Abstract
Autoimmune diseases are burdensome conditions that affect a significant fraction of the global population. The hallmark of autoimmune disease is a host's immune system being licensed to attack its tissues based on specific antigens. There are no cures for autoimmune diseases. The current clinical standard for treating autoimmune diseases is the administration of immunosuppressants, which weaken the immune system and reduce auto-inflammatory responses. However, people living with autoimmune diseases are subject to toxicity, fail to mount a sufficient immune response to protect against pathogens, and are more likely to develop infections. Therefore, there is a concerted effort to develop more effective means of targeting immunomodulatory therapies to antigen-presenting cells, which are involved in modulating the immune responses to specific antigens. In this review, we highlight approaches that are currently in development to target antigen-presenting cells and improve therapeutic outcomes in autoimmune diseases.

Madrid Paredes J, Versteeg JW, Vreman RA, Bloem LT. Agreement about Availability of Alternative Treatments for Innovative Drugs Assessed by the EMA and HTA Organizations. Clin Pharmacol Ther 2024; 116:136-146. [PMID: 38505926 DOI: 10.1002/cpt.3252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Accepted: 03/02/2024] [Indexed: 03/21/2024]
Abstract
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. Until 1 June 2022, 429 HTA drug-indication combinations were identified for these 97 drugs, of which 205 exactly matched the EMA's indication. For those, the overall agreement between the EMA and HTA organizations on whether alternative treatments were available was 87%. The agreement of HTA organizations with the EMA on whether available treatments were either pharmacological on-label, pharmacological off-label, or non-pharmacological was 87%, 21%, and 57%, respectively. For all 429 HTA drug-indication combinations, absence of alternative treatments as considered by HTA organizations was associated with a higher chance to provide added benefit: risk ratio 1.8 (95%-CI 1.4-2.3). In conclusion, although there was high overall agreement between the EMA and HTA organizations about whether alternative treatments exist, there were differences in the types of treatment considered. Parallel joint scientific consultations could inform drug developers about relevant alternative treatments to facilitate patient access to innovative drugs.

Abstract
Access to drugs for rare diseases constitutes a challenge to healthcare systems, especially those with public funding. This study aimed to map and summarize the criteria used by HTA agencies in different healthcare systems to evaluate reimbursement recommendations for orphan drugs. A comprehensive literature search was performed on the databases PubMed, LILACS, Scopus, and Embase and the gray literature (Google Scholar and websites of HTA agencies). Publications addressing the criteria used by HTA agencies in countries with public healthcare systems when evaluating reimbursement recommendations for orphan drugs were included. This scoping review included 23 studies published between 2014 and 2023, mostly consisting of reviews of HTA reports, guidance documents, and original articles. The criteria were mapped from 19 countries and ranked within three models of healthcare systems (National Health System, National Health Insurance, and Social Health Insurance). All models shared concerns about unmet needs and disease nature. In addition, NHS countries (e.g., United Kingdom, Sweden, and Italy) prioritized innovation and system-level impact, while SHI countries (e.g., Germany, France, the Netherlands) usually valued budget impact and employed expedited evaluation processes. This review provides a comprehensive understanding of the general tendencies of each healthcare system model in establishing differentiated criteria to address the challenges posed by the limited evidence and investment in the field of rare diseases.

Abstract
OBJECTIVES The study, conducted by the French National Authority for Health (HAS), aimed to identify available online health technology assessment (HTA) training tools for patients, specifically those used by HTA bodies (HTAbs) and major selected European and international patient and consumer groups (PCGs), to inform an HTA training approach for HAS. METHODS A literature search, a review of selected websites, semi-structured interviews with HTAbs and patient groups, and discussion within a dedicated working group to help target the needs and preferences of patients and consumers were conducted. Online HTA training tools relating to HTA and patient and public involvement (PPI), published or translated into English or French, were included in the study results. RESULTS Eighty-two online HTA training tools for patients and consumers were selected according to the specified inclusion criteria coming from sixteen international HTAbs, nine European and international PCGs, and thirteen other organizations. Two main categories emerged: the first relating to HTA and the second relating to PPI in HTA. The formats of these tools ranged from interactive and non-interactive formats with varying accessibility and assessment methods. No journal articles mentioned explicitly the content and format of PCG training tools. CONCLUSIONS This research served as a basis for HAS to develop their own HTA training tools and materials for patients and consumers. Two training tools were subsequently developed, guided by the needs and preferences of a patient and consumer working group, and were published on the HAS website in November 2022.

How are health technology assessment bodies responding to the assessment challenges posed by cell and gene therapy? BMC Health Serv Res 2023; 23:484.

Abstract
BACKGROUND The aims of this research were to provide a better understanding of the specific evidence needs for assessment of clinical and cost-effectiveness of cell and gene therapies, and to explore the extent that the relevant categories of evidence are considered in health technology assessment (HTA) processes. METHODS A targeted literature review was conducted to identify the specific categories of evidence relevant to the assessment of these therapies. Forty-six HTA reports for 9 products in 10 cell and gene therapy indications across 8 jurisdictions were analysed to determine the extent to which various items of evidence were considered. RESULTS The items to which the HTA bodies reacted positively were: treatment was for a rare disease or serious condition, lack of alternative therapies, evidence indicating substantial health gains, and when alternative payment models could be agreed. The items to which they reacted negatively were: use of unvalidated surrogate endpoints, single arm trials without an adequately matched alternative therapy, inadequate reporting of adverse consequences and risks, short length of follow-up in clinical trials, extrapolating to long-term outcomes, and uncertainty around the economic estimates. CONCLUSIONS The consideration by HTA bodies of evidence relating to the particular features of cell and gene therapies is variable. Several suggestions are made for addressing the assessment challenges posed by these therapies. Jurisdictions conducting HTAs of these therapies can consider whether these suggestions could be incorporated within their existing approach through strengthening deliberative decision-making or performing additional analyses.

Abstract
The field of regulatory affairs deals with the regulatory requirements for marketing authorization of therapeutic products. This field is facing a myriad of forces impacting all aspects of the development, regulation and value proposition of new therapeutic products. Changes in global megatrends, such as geopolitical shifts and the rise of the green economy, have emphasized the importance of manufacturing and supply chain security, and reducing the environmental impacts of product development. Rapid changes due to advances in science, digital disruption, a renewed focus on the centrality of the patient in all stages of therapeutic product development and greater collaboration between national regulatory authorities have been accelerated by the COVID-19 pandemic. This article will discuss the various trends that are impacting the development of new therapies for alleviating disease and how these trends therefore impact on the role of the regulatory affairs professional. We discuss some of the challenges and provide insights for the regulatory professional to remain at the forefront of these trends and prepare for their impacts on their work.

Abstract
OBJECTIVES Advanced therapy medicinal products (ATMPs) are drugs for human use for the treatment of chronic, degenerative, or life-threatening diseases that are based on genes, tissues, or cells. This article aimed to identify and critically review published economic analyses of ATMPs. METHODS A systematic review of economic analyses of ATMPs was undertaken. Study characteristics, design, sources of data, resources and unit costs, modeling and extrapolation methods, study results, and sensitivity analyses were assessed. RESULTS A total of 46 economic analyses of ATMP (from 45 articles) were included; 4 were cell therapy medicinal products, 33 gene therapy medicinal products, and 9 tissue-engineered products. 30 therapies had commercial marketing approval; 39 studies were cost-utility analysis, 5 were cost-effectiveness analysis, and 2 were cost only studies. Four studies predicted that the ATMP offered a step change in the management of the condition and 10 studies estimated that the ATMP would offer a lower mean cost. CONCLUSIONS Comparison with historical controls, pooling of data, and use of techniques such as mixture cure fraction models should be used cautiously. Sensitivity analyses should be used across a plausible range of prices. Clinical studies need to be designed to align with health technology assessment requirements, including generic quality of life, and payers should aim for clarity of criteria. Regulators and national payers should aim for compatibility of registers to allow interchange of data. Given the increasing reliance on industry-funded economic analyses, careful critical review is recommended.

Abstract
INTRODUCTION Assessing medical technologies for Alzheimer's disease (AD) creates challenges for current methods of value assessment. New value assessment approaches for AD are also needed. METHODS We adapted concepts from health economics to help guide decision makers to more informed decisions about AD therapies and diagnostics. RESULTS We propose a value framework based on five categories: perspective, value elements, analysis, reporting, and decision making. AD value assessments should include the perspective of the patient-caregiver dyad. We propose a broader array of value elements than currently used. Analytics and decision methods can synthesize evidence for all elements of value. Decisions should use a "deliberative appraisal" approach informed by the composite evidence and be transparently reported. DISCUSSION Using the proposed framework, the value of forthcoming innovations for AD may be more thoroughly assessed for and by all stakeholders. It can guide decision makers to carefully consider all relevant elements of value contributing to more holistic and transparent decision making. RESEARCH HIGHLIGHTS Alzheimer's disease challenges common methods of evaluating medical technology. Using current methods, new AD innovations might not be appropriately valued. Poor value assessments will adversely affect patient access to AD innovations. A full AD value framework expands perspective, elements, analysis, decision-making, reporting.
