Abstract
BACKGROUND AND OBJECTIVE Multiple myeloma is a rare incurable hematological cancer in which most patients relapse or become refractory to treatment. This systematic literature review aimed to critically review the existing economic models used in economic evaluations of systemic treatments for relapsed/refractory multiple myeloma and to summarize how the models addressed differences in the line of therapy and exposure to prior treatment. METHODS Following a pre-approved protocol, literature searches were conducted on 17 February, 2023, in relevant databases for models published since 2014. Additionally, key health technology assessment agency websites were manually searched for models published as part of submission dossiers since 2018. Reported information related to model conceptualization, structure, uncertainty, validation, and transparency were extracted into a pre-defined extraction sheet. RESULTS In total, 49 models assessing a wide range of interventions across multiple lines of therapy were included. Only five models specific to heavily pre-treated patients and/or those who were refractory to multiple treatment classes were identified. Most models followed a conventional simple methodology, such as partitioned survival (n = 28) or Markov models (n = 9). All included models evaluated specific interventions rather than the whole treatment sequence. Where subsequent therapies were included in the model, these were generally only considered from a cost and resource use perspective. The models generally used overall and progression-free survival as model inputs, although data were often immature. Sensitivity analyses were frequently reported (n = 41) whereas validation was only considered in less than half (n = 19) of the models. CONCLUSIONS Published economic models in relapsed/refractory multiple myeloma rarely followed an individual patient approach, mainly owing to the higher need for complex data assumptions compared with simpler modeling approaches. As many patients experience disease progression on multiple treatment lines, there is a growing need for modeling complex treatment strategies, leading to more sophisticated approaches in the future. Maintaining transparency, high reporting standards, and thorough analyses of uncertainty are crucial to support these advancements.

Impact of Disease Progression, Line of Therapy, and Response on Health-Related Quality of Life in Multiple Myeloma: A Systematic Literature Review. CLINICAL LYMPHOMA MYELOMA AND LEUKEMIA 2023; 23:426-437.e11. [PMID: 37061416 DOI: 10.1016/j.clml.2023.03.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 03/09/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023]
Abstract
This systematic literature review (SLR) was conducted to better understand the impact of disease progression, line of therapy, and clinical response on health-related quality of life (HRQoL) in patients with multiple myeloma (MM). Multiple databases were searched to identify records relating to HRQoL in adult patients with MM. Titles and abstracts were independently screened by 2 reviewers for inclusion based on pre-defined criteria. Records flagged for inclusion had full texts subsequently screened using the same method. A third round of screening was then conducted to identify studies that assessed the relationship of HRQoL to disease progression, line of therapy, or clinical response. Quality assessment was conducted on utility studies using the National Institute for Health and Care Excellence Quality Assessment Checklist for Health State Utility Values. After all rounds of screening were complete, 44 records (representing 41 studies) were included in the SLR. Thirty records reported data relating HRQoL to disease progression, 5 reported data relating HRQoL to line of therapy, and 19 reported data relating HRQoL to response. Despite a lack of homogeneity and small number of studies, the data show overall that progressive disease and increasing lines of therapy were associated with worsened patient HRQoL and increasing depth of response was associated with improved patient HRQoL. The findings from this SLR support that desirable treatment outcomes such as delayed progression, fewer lines of therapy, and achieving the deepest possible clinical response result in improved HRQoL in patients with MM.

Abstract
AIMS The goal of this study was to review the economic evaluations of health technologies in multiple myeloma (MM) and provide guidance and recommendations for future health economic analyses. MATERIALS AND METHODS A systemic literature review (SLR) was conducted on original economic assessment studies and structured review papers focusing on the studies in MM. The search was limited to English language papers published from 1 January 2000 onwards. Publications not applying any type of modelling methodology to describe disease progression and patient pathways over a specific time horizon were excluded. RESULTS A total of 2,643 publications were initially identified, of which 148 were eligible to be included in the full-text review phase. From these, 49 publications were included in the final analysis. Most published health economic analyses supported by models came from high-income countries. Evaluations from middle-income countries were rarely published. Diagnostic technologies were rarely modelled and integrated care had not been modelled. Very few models investigated MM treatments from a societal perspective and there was a relative lack of evaluations regarding minimal residual disease (MRD). LIMITATIONS Limitations of the publications included differences between trial populations and modelled populations, justification of methods, lack of confounder analyses, and small trial populations. Limitations of our study included the infeasibility of comparing MM economic evaluations due to the significant variance in modelled therapeutic lines and indications, and the relative scarcity of published economic evaluations from non-high-income countries. CONCLUSIONS As published economic models lacked many of the elements of the complex and heterogeneous patient pathways in MM and they focused on single decision problems, a thorough, open-source economic whole disease modelling framework is needed to assess the economic value of a wide range of technologies across countries with various income levels with a more detailed view on MM, by including patient-centric and societal aspects.

Cost utility and budget impact analysis of dexamethasone compared with bortezomib and lenalidomide for the treatment of second line multiple myeloma from a South African public health perspective. Cost Eff Resour Alloc 2022; 20:69. [PMID: 36510230 PMCID: PMC9746097 DOI: 10.1186/s12962-022-00399-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 11/09/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Multiple myeloma is an incurable haematological malignancy that is associated with a high probability of relapse. The survival of relapsed patients has been greatly improved by the development of novel drugs such as lenalidomide and bortezomib. We assessed the cost-effectiveness of these drugs as second-line treatment for relapsed/refractory multiple myeloma (RRMM) patients in the South African public health care system. METHODS We modelled 3 treatment strategies for second-line RRMM treatment: dexamethasone (standard of care), bortezomib (BORT) and lenalidomide plus dexamethasone (LEN/DEX) from the South African public health perspective. For each strategy we modelled a hypothetical cohort of relapsed/refractory multiple myeloma patients using a three-state Markov model over a 15-year time horizon. Efficacy and utilization data were obtained from the MM009/010 and APEX trials and external studies. Price and cost data were from local sources and presented in 2021 South African Rands. Outcomes were reported in quality adjusted life years (QALYs). Incremental cost effectiveness ratios (ICERs) were calculated for BORT and LEN/DEX and compared to a local cost-effectiveness threshold of R38 500 per DALY averted using the assumption that 1 DALY averted is equal to 1 QALY gained. A budget impact analysis was conducted to evaluate the financial impact of the introduction of BORT and LEN/DEX, respectively. Deterministic sensitivity analysis was undertaken to account for parameter uncertainties. RESULTS The modelled total costs of DEX, BORT and LEN/DEX were estimated to be R8 312, R234 996 and R1 135 323, respectively. DEX treatment provided 1.14 QALYs while BORT and LEN/DEX treatments provided 1.49 and 2.22 QALYs, respectively. The ICER of BORT versus DEX was R654 649 and that of LEN/DEX versus BORT was R1 225 542. Both BORT and LEN/DEX treatments were not cost-effective relative to a cost-effectiveness threshold of R38 500 per DALY averted. Both BORT and LEN/DEX significantly increase the 1 year budget-cost of RRMM treatment. CONCLUSION Both BORT and LEN/DEX treatments are unlikely to be cost-effective strategies for second-line treatment of RRMM in South Africa. The results indicate that the drug prices of lenalidomide and bortezomib are key drivers of value for money. Price reductions could potentially make BORT more cost-effective.

Abstract
BACKGROUND The expansion of advanced expensive therapeutic innovations for Multiple Myeloma (MM) led to increased disclosure of economic evaluations. The present analysis systematically reviewed and appraised the reporting quality of economic evaluations in MM. METHODOLOGY A comprehensive literature search in Ovid, MEDLINE(R), PubMed, and Cochrane libraries was conducted for studies published in the past decade. Two independent authors performed study selection and data extraction in a standardized form. Study methodological quality assessment was performed using 10-item Drummond's tool. RESULTS Of potentially eligible 1150 retrieved studies, 17 met eligibility criteria. Six evaluations (35%) were in newly diagnosed MM and 11 (65%) in relapse refractory (RR) MM. Nine studies (53%) embraced the payer's perspective, five (29%) adopted health care system, one (6%) societal and two did not report. Six (35%) employed partitioned survival model, 4(24%) discrete event simulation, 4(24%) Markov model and 2(12%) used decision tree model. The methodological quality has improved significantly; 16 (94%) studies comprehended a well-defined question by affirming the analysis perspective and examined both costs and outcomes while 13 (71%) provided a comprehensive description of competing alternatives. CONCLUSION The addition of novel drugs to the treatment armamentarium of MM is considerably cost-effective. The evaluations became more frequent, methodological quality has improved in the last decade.
