Remuneration of donors for cell and gene therapies: an update on the principles and perspective of the World Marrow Donor Association.

The cell and gene therapy (CGT) sector has witnessed significant advancement over the past decade, the inception of advanced therapy medicinal products (ATMPs) being one of the most transformational. ATMPs treat serious medical conditions, in some cases providing curative therapy for seriously ill patients. There is interest in pivoting the ATMP development from autologous based treatments to allogenic, to offer faster and greater patient access that should ultimately reduce treatment costs. Consequently, starting material from allogenic donors is required, igniting ethical issues associated with financial gains and donor remuneration within CGT. The World Marrow Donor Association (WMDA) established the Cellular Therapy Committee to identify the role WMDA can play in safeguarding donors and patients in the CGT field. Here we review key ethical principles in relation to donating cellular material for the CGT field. We present the updated statement from WMDA on donor remuneration, which supports non-remuneration as the best way to ensure the safety and well-being of donors and patients alike. This is in line with the fundamental objective of the WMDA to maintain the health and safety of volunteer donors while ensuring high-quality stem cell products are available for all patients. We acknowledge that the CGT field is evolving at a rapid pace and there will be a need to review this position as new practices and applications come to pass.

Advancing our understanding of bioreactors for industrial-sized cell culture: health care and cellular agriculture implications.

Bioreactors are advanced biomanufacturing tools that have been widely used to develop various applications in the fields of health care and cellular agriculture. In recent years, there has been a growing interest in the use of bioreactors to enhance the efficiency and scalability of these technologies. In cell therapy, bioreactors have been used to expand and differentiate cells into specialized cell types that can be used for transplantation or tissue regeneration. In cultured meat production, bioreactors offer a controlled and efficient means of producing meat without the need for animal farming. Bioreactors can support the growth of muscle cells by providing the necessary conditions for cell proliferation, differentiation, and maturation, including the provision of oxygen and nutrients. This review article aims to provide an overview of the current state of bioreactor technology in both cell therapy and cultured meat production. It will examine the various bioreactor types and their applications in these fields, highlighting their advantages and limitations. In addition, it will explore the future prospects and challenges of bioreactor technology in these emerging fields. Overall, this review will provide valuable insights for researchers and practitioners interested in using bioreactor technology to develop innovative solutions in the biomanufacturing of therapeutic cells and cultured meat.

Health Care Resource Utilization and Total Costs of Care Among Patients with Diffuse Large B Cell Lymphoma Treated with Chimeric Antigen Receptor T Cell Therapy in the United States.

The use of chimeric antigen receptor (CAR) T-cell therapy after a second relapse of diffuse large B-cell lymphoma (DLBCL) has shown favorable efficacy in clinical trials; however, little is known about health care resource utilization (HCRU) and costs of CAR T cell therapy for patients treated in real-world settings. We assessed treatment patterns, HCRU, costs, and safety in patients receiving CAR T cell therapy for relapsed or refractory DLBCL across 3 US commercial claims databases. Adults with DLBCL treated with CAR T cell therapy were identified in the following 3 claims databases: Optum® Clinformatics® Data Mart, IBM MarketScan® Commercial & Medicare Database, and IQVIA PharMetrics® Plus. Mean total costs were calculated and adjusted to 2019 US dollars. HCRU and costs within 3 months of infusion were stratified by safety events of interest, including neurological events (NEs) and cytokine release syndrome (CRS), identified via unvalidated algorithms designed based on expert medical opinion. A total of 191 patients receiving CAR T cell therapy were identified across the databases; their median age ranged from 56 to 67 years, and 63% to 75% were male. Most patients (88% to 98%) received CAR T cell infusions in the inpatient setting; 30% to 75% received bridging therapy. CRS was reported in 75% to 84% of patients (severe CRS, 15% to 32%), and NEs were reported in 58% to 69% (severe NEs, 25% to 43%). Mean total inpatient hospital days ranged from 17 to 22 days and increased with severe CRS (19 to 27 days) or severe NEs (22 to 29 days). Mean total health care expenditures ranged from $380,000 to $526,000 and were generally higher with severe CRS or NEs (∼$406,000 to $679,000). HCRU and costs associated with CAR T cell therapy may vary in the real world depending on several factors, including occurrence and severity of adverse events.

The National Heart, Lung, and Blood Institute-funded Production Assistance for Cellular Therapies (PACT) program: Eighteen years of cell therapy.

The Production Assistance for Cellular Therapies (PACT) Program, is funded and supported by the US Department of Health and Human Services' National Institutes of Health (NIH) National Heart Lung and Blood Institute (NHLBI) to advance development of somatic cell and genetically modified cell therapeutics in the areas of heart, lung, and blood diseases. The program began in 2003, continued under two competitive renewals, and ended June 2021. PACT has supported cell therapy product manufacturing, investigational new drug enabling preclinical studies, and translational services, and has provided regulatory assistance for candidate cell therapy products that may aid in the repair and regeneration of damaged/diseased cells, tissues, and organs. PACT currently supports the development of novel cell therapies through five cell processing facilities. These facilities offer manufacturing processes, analytical development, technology transfer, process scale-up, and preclinical development expertise necessary to produce cell therapy products that are compliant with Good Laboratory Practices, current Good Manufacturing Practices, and current Good Tissue Practices regulations. The Emmes Company, LLC, serves as the Coordinating Center and assists with the management and coordination of PACT and its application submission and review process. This paper discusses the impact and accomplishments of the PACT program on the cell therapy field and its evolution over the duration of the program. It highlights the work that has been accomplished and provides a foundation to build future programs with similar goals to advance cellular therapeutics in a coordinated and centralized programmatic manner to support unmet medical needs within NHLBI purview.

[Economics and management of CAR T- cell therapy : Status quo and future perspectives]. / Ökonomie und Management bei der CAR-T-Zell-Therapie : Status quo und Ausblick.

BACKGROUND: Virtually no other topic has attracted more attention in oncology in recent years than chimeric antigen receptor (CAR) T­cell therapy (CAR T). On the one hand it opens up completely new treatment options for cancer patients, while on the other it generates treatment costs exceeding € 300,000 per treatment. OBJECTIVES: The aim of this work is to analyze the economic, procedural and organizational challenges of CAR T­cell therapy from the perspective of the service provider, the cost-bearer and the pharmaceutical manufacturer. MATERIAL AND METHODS: The current German diagnosis-related-group (G-DRG) catalog, the G­DRG tariff, of the German Federal Joint Committee (G-BA) guidelines and G­DRG coding principles were used to evaluate the reimbursement and remuneration system in Germany. Practical experiences of medical sites were integrated in the analysis. RESULTS: The findings demonstrate great economic challenges especially from the perspective of a CAR T site. Increasing certification and qualification efforts lead to financial pressure. Insufficient reimbursement and inadequate cost-covering for CAR T treatment result in budget restrictions for hospitals. CONCLUSION: High drug costs as well as enormous personnel and infrastructural requirements demand transparent and sufficient reimbursement for hospitals. Interaction between hospital and pharmaceutical manufacturer in the CAR T process might enable new means of cooperation.

Burn Center Organization and Cellular Therapy Integration: Managing Risks and Costs.

The complex management of severe burn victims requires an integrative collaboration of multidisciplinary specialists in order to ensure quality and excellence in healthcare. This multidisciplinary care has quickly led to the integration of cell therapies in clinical care of burn patients. Specific advances in cellular therapy together with medical care have allowed for rapid treatment, shorter residence in hospitals and intensive care units, shorter durations of mechanical ventilation, lower complications and surgery interventions, and decreasing mortality rates. However, naturally fluctuating patient admission rates increase pressure toward optimized resource utilization. Besides, European translational developments of cellular therapies currently face potentially jeopardizing challenges on the policy front. The aim of the present work is to provide key considerations in burn care with focus on architectural and organizational aspects of burn centers, management of cellular therapy products, and guidelines in evolving restrictive regulations relative to standardized cell therapies. Thus, based on our experience, we present herein integrated management of risks and costs for preserving and optimizing clinical care and cellular therapies for patients in dire need.

The impact of COVID-19 on the cell and gene therapies industry: Disruptions, opportunities, and future prospects.

Coronavirus 2019 (COVID-19) has caused significant disruption to the cell and gene therapy (CGT) industry, which has historically faced substantial complexities in supply of materials, and manufacturing and logistics processes. As decision-makers shifted their priorities to COVID-19-related issues, the challenges in market authorisation, and price and reimbursement of CGTs were amplified. Nevertheless, it is encouraging to see that some CGT developers are adapting their efforts toward the development of promising COVID-19-related therapeutics and vaccines. Manufacturing resilience, digitalisation, telemedicine, value-based pricing, and innovative payment mechanisms will be increasingly harnessed to ensure that market access of CGTs is not severely disrupted.

Cord blood beyond transplantation: can we use the experience to advance all cell therapies?

Unrelated cord blood (CB) units, already manufactured, fully tested and stored, are high-quality products for haematopoietic stem cell transplantation and cell therapies, as well as an optimal starting material for cell expansion, cell engineering or cell re-programming technologies. CB banks have been pioneers in the development and implementation of Current Good Manufacturing Practices for cell-therapy products. Sharing their technological and regulatory experience will help advance all cell therapies, CB-derived or not, particularly as they transition from autologous, individually manufactured products to stored, 'off-the shelf' treatments. Such strategies will allow broader patient access and wide product utilisation.

The insurability of innovative pharmaceutical cancer technologies.

The scientific literature, including several papers published in the IJHPR, has raised the issue of the spiraling cost of cancer treatment, including that of cancer drugs and other technologies such as gene and cell therapies. In this perspective, we review three criteria for insurability and show that they may not be met.First, the uncertain trends in the cost of innovative pharmaceutical and other cancer technologies make the maximum possible loss per event very difficult to predict and to manage in terms of insurer solvency. Second, the uncertainty of the price, the period that a drug or other cancer care technology will be administered and the number of individuals that will need the technology makes it difficult to predict future insurance premiums and whether they will be affordable to the target population. Third, public coverage needs to be consistent with societal values. However, pressure to limit public coverage will gradually increase as the possibilities of innovative pharmaceutical cancer technologies expand, thus transferring the burden onto commercial insurance. This is a phenomenon that is virtually impossible to predict accurately, but which will certainly undermine the status of health as a social good.We conclude that the financial risk arising from the use of innovative pharmaceutical cancer technologies fails to meet the aforementioned criteria, thus raising questions as to the sustainability of commercial insurance for cancer treatment and suggesting the need for the state to take greater responsibility for covering this financial risk in the future.

HTA methodology and value frameworks for evaluation and policy making for cell and gene therapies.

This last decade has been marked by significant advances in the development of cell and gene (C&G) therapies, such as gene targeting or stem cell-based therapies. C&G therapies offer transformative benefits to patients but present a challenge to current health technology decision-making systems because they are typically reviewed when clinical efficacy data are very limited and when there is uncertainty about the long-term durability of outcomes. These challenges are not unique to C&G therapies, but they face more of these barriers, reflecting the need for adapting existing value assessment frameworks. Still, C&G therapies have the potential to be cost-effective even at very high price points. The impact on healthcare budgets will depend on the success rate of pipeline assets and on the extent to which C&G therapies will expand to wider pathologies beyond rare or ultra-rare diseases. Getting pricing and reimbursement models right is important for incentivising research and development investment while not jeopardising the sustainability of healthcare systems. Payers and manufacturers therefore need to acknowledge each other's constraints-limitations in the evidence generation on the manufacturer side, budget considerations on the payer side-and embrace innovative thinking and approaches to ensure timely delivery of therapies to patients. Several experts in health technology assessment and clinical experts have worked together to produce this publication and identify methodological and policy options to improve the assessment of C&G therapies, and make it happen better, faster and sustainably in the coming years.

Transitioning from development to commercial: risk-based guidance for critical materials management in cell therapies.

A key hurdle to ensuring patient access to cell and gene therapies (CGTs) and continued growth of the industry is the management of raw materials. The combination of rapid growth, individual product and process complexity and limited industry-specific guidance or awareness presents non-obvious risk mitigation challenges for transitioning from development to clinical application. Understanding, assessing and mitigating the varied raw material risks for CGT products during product and clinical development are critical for ensuring smooth transitions into commercialization and for preventing interruption of product supply to patients. This article presents a risk-based approach driven by concerns for patient safety that can help focus and coordinate efforts to address the most critical risk factors. Highlighted are some of the highest risk materials common to the manufacture of many CGTs, including the primary starting material, culture media, reagents and single-use components. Using a hypothetical gene-edited cell therapy as an example, we describe the general manufacturing process and subsequently incorporate the described methodology to perform a sample risk assessment. The practical approach described herein is intended to assist CGT manufacturers and suppliers in actively assessing materials early in development to provide a basic starting point for mitigating risks experienced when translating CGT products for clinical and long-term commercial application.

What does cell therapy manufacturing cost? A framework and methodology to facilitate academic and other small-scale cell therapy manufacturing costings.

BACKGROUND AIMS: Recent technical and clinical advances with cell-based therapies (CBTs) hold great promise in the treatment of patients with rare diseases and those with high unmet medical need. Currently the majority of CBTs are developed and manufactured in specialized academic facilities. Due to small scale, unique characteristics and specific supply chain, CBT manufacturing is considered costly compared to more conventional medicinal products. As a result, biomedical researchers and clinicians are increasingly faced with cost considerations in CBT development. The objective of this research was to develop a costing framework and methodology for academic and other small-scale facilities that manufacture cell-based therapies. METHODS: We conducted an international multi-center costing study in four facilities in Europe using eight CBTs as case studies. This study includes costs from cell or tissue procurement to release of final product for clinical use. First, via interviews with research scientists, clinicians, biomedical scientists, pharmacists and technicians, we designed a high-level costing framework. Next, we developed a more detailed uniform methodology to allocate cost items. Costs were divided into steps (tissue procurement, manufacturing and fill-finish). The steps were each subdivided into cost categories (materials, equipment, personnel and facility), and each category was broken down into facility running (fixed) costs and operational (variable) costs. The methodology was tested via the case studies and validated in developer interviews. Costs are expressed in 2018 euros (€). RESULTS: The framework and methodology were applicable across facilities and proved sensitive to differences in product and facility characteristics. Case study cost estimates ranged between €23 033 and €190 799 Euros per batch, with batch yield varying between 1 and 88 doses. The cost estimations revealed hidden costs to developers and provided insights into cost drivers to help design manufacturing best practices. CONCLUSIONS: This framework and methodology provide step-by-step guidance to estimate manufacturing costs specifically for cell-based therapies manufactured in academic and other small-scale enterprises. The framework and methodology can be used to inform and plan cost-conscious strategies for CBTs.

Towards a common framework for defining ancillary material quality across the development spectrum.

Ancillary materials (AMs) play a critical role in the manufacture of cell and gene therapies, and best practices for their quality management are the subject of ongoing discussion. Given that the final product cannot be sterilized, AM quality becomes increasingly critical to the clinical advancement of cell and gene therapies. Despite a lack of direct legislative direction regarding AM quality, internationally harmonized guidance is available from several industry-standard bodies that describe the principles and application of a risk-based approach to AM qualification and related supply-chain risk management. According to a best-practice risk-based approach, AMs must be adequately qualified to a degree that reflects the level of risk the material presents to patient safety and the drug product's specification. This general approach can be implemented in different ways, and balancing quality with cost of goods is critical to the cost-effective manufacture of advanced therapy medicinal products. In some cases, it may be preferable or necessary to use AMs that are produced in compliance with current Good Manufacturing Practice. However, developers may be able to suppress manufacturing costs without undermining safety or regulatory compliance in the case that a material presents a lower risk profile. Despite a great deal of attention and interest in the quality of AMs in the cell and gene therapy space, there is still a need for greater harmonization to create a shared understanding of what constitutes a risk-based approach to AM production and sourcing. In this article, we propose a staged approach to AM quality that achieves a balance between the competing demands of risk mitigation and cost of goods containment at the various stages of AM quality development. Our novel, heuristic framework for communication among AM suppliers, users and regulators aims to bring down development and manufacturing costs and lessen the workload around regulatory compliance.

There is no evidence-based information for the use of cell-based therapies in knee osteoarthritis.

A multiscale simulation framework for the manufacturing facility and supply chain of autologous cell therapies.

BACKGROUND AIMS: Autologous cell therapy (AuCT) is an emerging therapeutic treatment that is undergoing transformation from laboratory- to industry-scale manufacturing with recent regulatory approvals. Various challenges facing the complex AuCT manufacturing and supply chain process hinder the scale out and broader application of this highly potent treatment. METHODS: We present a multiscale logistics simulation framework, AuCT-Sim, that integrates novel supply chain system modeling algorithms, methods, and tools. AuCT-Sim includes a single facility model and a system-wide network model. Unique challenges of the AuCT industry are analyzed and addressed in AuCT-Sim. Decision-supporting tools can be developed based on this framework to explore "what-if" manufacturing and supply chain scenarios of importance to various cell therapy stakeholder groups. RESULTS: Two case studies demonstrate the decision-supporting capability of AuCT-Sim where one investigates the optimal reagent base stocking level, and the other one simulates a reagent supply disruption event. These case studies serve as guidelines for designing computational experiments with AuCT-Sim to solve specific problems in AuCT manufacturing and supply chain. DISCUSSION: This simulation framework will be useful in understanding the impact of possible manufacturing and supply chain strategies, policies, regulations, and standards informing strategies to increase patient access to AuCT.

Towards Automated Manufacturing for Cell Therapies.

PURPOSE OF REVIEW: Many cell therapy products are beginning to reach the commercial finish line and a rapidly escalating pipeline of products are in clinical development. The need to develop manufacturing capability that will support a successful commercial business model has become a top priority as many cell therapy developers look to secure long-term visions to enable both funding and treatment success. RECENT FINDINGS: Manufacturing automation is both highly compelling and very challenging at the same time as a key tactic to address quality, cost of goods, scale, and sustainability that are fundamental drivers for commercially viable manufacturing. This paper presents an overview and strategic drivers for application of automation to cell therapy manufacturing. It also explores unique automation considerations for patient-specific cell therapy (PSCT) where each full-scale lot is for one patient vs off-the-shelf cell therapy (OTSCT) where a full-scale lot will treat many patients, and finally some practical considerations for implementing automation.
