RESUMO
OBJECTIVES: This study aimed to systematically review evidence on the cost-effectiveness of chimeric antigen receptor T-cell (CAR-T) therapies for patients with cancer. METHODS: Electronic databases were searched in October 2022 and updated in September 2023. Systematic reviews, health technology assessments, and economic evaluations that compared costs and effects of CAR-T therapy in patients with cancer were included. Two reviewers independently screened studies, extracted data, synthesized results, and critically appraised studies using the Philips checklist. Cost data were presented in 2022 US dollars. RESULTS: Our search yielded 1809 records, 47 of which were included. Most of included studies were cost-utility analysis, published between 2018 and 2023, and conducted in the United States. Tisagenlecleucel, axicabtagene ciloleucel, idecabtagene vicleucel, ciltacabtagene autoleucel, lisocabtagene maraleucel, brexucabtagene autoleucel, and relmacabtagene autoleucel were compared with various standard of care chemotherapies. The incremental cost-effectiveness ratio (ICER) for CAR-T therapies ranged from $9424 to $4 124 105 per quality-adjusted life-year (QALY) in adults and from $20 784 to $243 177 per QALY in pediatric patients. Incremental cost-effectiveness ratios were found to improve over longer time horizons or when an earlier cure point was assumed. Most studies failed to meet the Philips checklist due to a lack of head-to-head comparisons and uncertainty surrounding CAR-T costs and curative effects. CONCLUSIONS: CAR-T therapies were more expensive and generated more QALYs than comparators, but their cost-effectiveness was uncertain and dependent on patient population, cancer type, and model assumptions. This highlights the need for more nuanced economic evaluations and continued research to better understand the value of CAR-T therapies in diverse patient populations.

BACKGROUND: Traditionally, economic evaluations have engaged clinicians and policymakers; however, patients and their caregivers have insight that can ensure that the economic evaluation process appropriately reflects disease consequences and adequately addresses their priorities related to treatment. OBJECTIVE: We aimed to identify patient priorities to inform an early economic evaluation of chimeric antigen receptor T-cell therapy for adults with relapsed or refractory B-cell acute lymphoblastic leukemia. METHODS: We conducted two online group discussions of four participants each, involving patients with experience of hematological cancer and a caregiver. We used an adapted version of the nominal group technique, a consensus-building discussion approach, to generate focused qualitative data. RESULTS: Patients and a caregiver acknowledged both the costs directly related to clinical care, such as the out-of-pocket cost of drugs, and the indirect treatment costs, such as the cost of transport, accommodation, and food. The emotional and physical toll of treatment and the influence of treatment on employment and education were additional costs emphasized by participants. Treatment benefits prioritized by participants included the efficacy of treatment, manageable side effects, improved quality of life, accessibility of treatment, and short treatment duration. CONCLUSIONS: Engaging patients and caregivers in an early economic evaluation could help identify additional costs and benefits of therapies that are not typically recognized in economic evaluations but have the potential to increase the commercial viability of novel therapies. This research also demonstrates how patients and caregivers can be engaged at different levels in the development of early economic evaluation models.

INTRODUCTION: Chimeric antigen receptor T-cell (CAR-T) therapy is a class of immunotherapy. An economic evaluation conducted at an early stage of development of CAR-T therapy for treatment of adult relapsed or refractory acute lymphoblastic leukaemia could provide insight into factors contributing to the cost of treatment, the potential clinical benefits, and what the health system can afford. Traditionally, stakeholders are engaged in certain parts of health technology assessment processes, such as in the identification and selection of technologies, formulation of recommendations, and implementation of recommendations; however, little is known about processes for stakeholder engagement during the conduct of the assessment. This is especially the case for economic evaluations. Stakeholders, such as clinicians, policy-makers, patients, and their support networks, have insight into factors that can enhance the validity of an economic evaluation model. This research outlines a specific methodology for stakeholder engagement and represents an avenue to enhance health economic evaluations and support the use of these models to inform decision making for resource allocation. This protocol may inform a tailored framework for stakeholder engagement processes in future economic evaluation model development. METHODS AND ANALYSIS: We will involve clinicians, healthcare researchers, payers, and policy-makers, as well as patients and their support networks in the conduct and verification of an early economic evaluation of a novel health technology to incorporate stakeholder-generated knowledge. Three stakeholder-specific focus groups will be conducted using an online adaptation of the nominal group technique to elicit considerations from each. This study will use CAR-T therapy for adults with relapsed or refractory B-cell acute lymphoblastic leukaemia as a basis for investigating broader stakeholder engagement processes. ETHICS AND DISSEMINATION: This study received ethics approval from the Ottawa Hospital Research Institute Research Ethics Board (REB 20200320-01HT) and the results will be shared via conference presentations, peer-reviewed publications, and ongoing stakeholder engagement.

We assessed the extent to which the publication of clinical trial results of innovative cell-based interventions reflects International Society for Stem Cell Research best practice guidelines. We assessed: (1) characteristics and time to publication of completed trials; (2) quality of reported trials; and (3) results of published trials. We identified and analyzed publications from 1,052 novel stem cell clinical trials: 179 (45.4%) of 393 completed trials had published results; 48 trials were registered by known stem cell tourism clinics, none of which reported results. Completed non-industry-sponsored trials initially published more rapidly, but differences with industry-sponsored trials decreased over time. Most publications reported safety, and 67.3% (mainly early-stage trials) reported positive outcomes. A higher proportion of industry trials reported positive efficacy. Heightened patient expectations for stem cell therapies give rise to ethical obligations for the transparent conduct of clinical trials. Reporting guidelines need to be developed that are specific to early-phase clinical trials.

Significant investments in regenerative medicine necessitate discussion to align evidentiary requirements and decision-making considerations from regulatory, health system payer and developer perspectives. Only with coordinated efforts will the potential of regenerative medicine be realized. We report on discussions from two workshops sponsored by NICE, University of Alberta, Cell Therapy Catapult and Centre for Commercialization of Regenerative Medicine. We discuss methods to support the assessment of value for regenerative medicine products and services and the synergies that exist between market authorization and reimbursement regulations and practices. We discuss the convergence in novel adaptive licensing practices that may promote the development and adoption of novel therapeutics that meet the needs of healthcare payers.

Patients with coexisting medical problems may suffer increased toxicity and reduced quality of life after autologous hematopoietic stem cell transplantation (HSCT). The benefit of high-dose therapy for some patients with multiple myeloma (MM) is debatable. Decision tools that aid in identifying those patients with MM most suited for autologous HSCT may avoid the risk of excess toxicity. An objective assessment of comorbidities was performed in 126 patients with MM undergoing autologous HSCT using the Charlson comorbidity index (CCI), the hematopoietic cell transplantation comorbidity index (HCT-CI), and a modified pretransplantation assessment of mortality (mPAM) to determine the strength of association with increased transplantation-related toxicity and increased length of hospital stay (LOS). Any comorbidity scored using the CCI or HCT-CI (score > 0) was associated with an increased number of organ systems with serious toxicity (at least grade 2 toxicity using the Seattle criteria), an increased total sum of toxicity grades for all organs, and prolonged LOS. An mPAM score > or = 24 was associated with increased LOS. When considering autologous HSCT for a patient with MM, assessment of comorbidities using the CCI or HCT-CI may assist in predicting the risk of transplantation-related toxicity as an adjunct to physician judgment and patient preference.
