van Hest N, Morten P, Stubbs K, Trevor N. Use of Minimal Residual Disease Status to Reduce Uncertainty in Estimating Long-term Survival Outcomes for Newly Diagnosed Multiple Myeloma Patients. JOURNAL OF HEALTH ECONOMICS AND OUTCOMES RESEARCH 2023; 10:1-9. [PMID: 36688213 PMCID: PMC9826714 DOI: 10.36469/001c.56072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 11/23/2022] [Indexed: 06/17/2023]
Abstract
Background: Demonstrating the cost-effectiveness of new treatments for multiple myeloma (MM) often relies on the extrapolation of overall survival (OS) trial data. This method can introduce uncertainty in long-term survival estimates if OS data are immature, as is often the case in newly diagnosed MM (NDMM). We explore the use of the relationship between minimal residual disease (MRD) status and OS to reduce uncertainty of long-term survival outcomes. Objectives: To evaluate if uncertainty in long-term modeled outcomes in NDMM is reduced using a response-based partitioned survival model (PSM), whereby patients were categorized as MRD-positive or -negative, relative to a standard PSM, when OS data are immature. Methods: Standard and response-based PSMs, estimating patient life-years (LYs) over a lifetime horizon, were developed for NDMM patients treated with bortezomib, thalidomide, and dexamethasone (BTd) with or without daratumumab as induction and consolidation therapy. In the standard PSM, LYs were determined by extrapolations from individual patient data from CASSIOPEIA. In the response-based PSM, survival was dependent on MRD status at the time of the response assessment via a landmark analysis. Cox-proportional hazard ratios from external sources and CASSIOPEIA informed the relationship for OS between MRD-positive and MRD-negative, and between patients receiving BTd and daratumumab plus BTd, respectively. Uncertainty was assessed by comparing LYs and OS extrapolations from deterministic and probabilistic analyses. Results: This response-based PSM demonstrated reduced uncertainty in long-term survival outcomes compared with the standard PSM (range across extrapolations of 3.4 and 7.7 LYs for daratumumab plus BTd and BTd, respectively, vs 14.8 and 11.8 LYs for the standard PSM). It also estimated a narrower interquartile range of LYs in the probabilistic analyses for the majority of parametric extrapolations. Discussion: Alternative methods to estimate long-term survival outcomes, such as a response-based PSM, can reduce uncertainty in modeling predictions around cost-effectiveness estimates for health technology assessment bodies and payers, thereby supporting faster market access for novel therapies with immature survival data. Conclusions: Use of MRD status in a response-based PSM reduces uncertainty in modeling long-term survival in patients with NDMM and provides a greater number of clinically plausible extrapolations compared with a standard PSM.

Patient and Caregiver Experience Decision Factors in Treatment Decision Making: Results of a Systematic Literature Review of Multiple Myeloma Decision Aids. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2023; 26:39-49. [PMID: 35613958 DOI: 10.1016/j.jval.2022.04.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 02/18/2022] [Accepted: 04/08/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVES Decision-aids (DAs) may facilitate shared decision-making for patients and caregivers, by providing evidence-based information to assist healthcare professionals, patients, and caregivers in making choices about aspects of care, and/or highlighting decision factors to discuss with the potential of altering the treatment decision. These decision factors may not be well integrated in DAs. METHODS A systematic literature review was conducted in the field of multiple myeloma (MM) on peer-reviewed publications, extended with a gray literature search. Data on whether and how patient and caregiver experience elements, other than survival and physical quality of life, were mentioned as decision factors in the identified MM DAs were extracted and analyzed qualitatively. RESULTS Seventy MM DAs were found and analyzed; 51% of DAs mentioned any patient non-routinely assessed experience decision factors and only 17% mentioned any caregiver-related information. One hundred and forty potential decision factors were extracted, deduplicated and categorized into the following categories: 1) financial, 2) mode of administration / transportation issues, 3) personal beliefs and values, 4) emotional and social quality of life, 5) other medical information, 6) availability of social support, 7) caregiver burden. None of the DAs presented a comprehensive framework on all seven categories of decision factors being consider when mapping patient and caregiver experience value elements in MM. CONCLUSIONS Based on available DAs, we recommend a set of patient and caregiver experience decision factors that have the potential to affect treatment choices of patients with MM, which should be included in DAs, including MM clinical guidelines.

Abstract
AbstractBackgroundA pilot external quality assurance (EQA) survey for the free light chain (FLC) assay was developed and implemented in Korea.MethodsSurvey data over 6 years (2010–2015) were collected retrospectively and Sigma metrics were calculated for method-specific peer groups.ResultsNineteen to 29 laboratories participated in the EQA survey, and nephelometric (20%) and turbidimetric (80%) methods were used. Using a previously published clinically relevant reference change value (RCV) of 54.5% as the tolerance limit, the method-specific median Sigma metrics of kappa (κ) and lambda (λ) FLC achieved greater than Three-Sigma for 86–97% of all EQA distributions, and Five-Sigma for 48–72% of all distributions.ConclusionsThis EQA analysis of FLC assay applied clinically relevant quality specifications using Sigma metrics. During the 6-year EQA survey, we found that most of the results from participating laboratories meet clinically relevant quality specifications. In addition, method-specific differences were noted for λ FLC, at FLC concentrations above the initial measuring range that require a sample dilution.

Abstract
The study aims to examine the treatment effect and adverse reactions of patients with newly diagnosed MM receiving different bortezomib-based regimens.This was a retrospective study of patients with newly diagnosed MM and who were treated with bortezomib-based combined chemotherapy at the Department of Hematology of the 2 affiliated hospitals of Wenzhou Medical University between July 2009 and May 2016. Cox proportion hazard multivariate analyses were carried out to assess the differences in treatment effect and adverse events between standard (1.3 mg/m on days 1, 4, 8, 11) and weekly (1.6 mg/m on days 1, 8, 15) cohorts, as well as the differences between intravenous injection and subcutaneous injection therapy. Progression-free survival (PFS) and overall survival (OS) were assessed using Kaplan-Meier method and the log-rank test.Among the 117 patients, 78 patients were treated with bortezomib standard therapy and 39 patients were treated with bortezomib weekly therapy (all with intravenous injection). In all patients, the treatment strategy was not independently associated with PFS or OS. The patients in the weekly therapy group had less thrombocytopenia events than those in the standard therapy group. The subcutaneous route had similar treatment effect as the intravenous route, but the incidence of peripheral neuropathy was lower.The once-weekly bortezomib regimen was similar in effectiveness to standard therapy in treating patients with newly diagnosed MM, but the incidence of thrombocytopenia was lower with the weekly regimen compared with the standard regimen.

Abstract
INTRODUCTION While myeloma is an incurable malignancy, developments in disease management have led to increased life expectancy in recent years. Treatment typically involves stem-cell transplantation. Increased survival rates equate to more patients living with the burden of both the disease and its treatment for increasing number of years, rendering myeloma a long-term condition.Evidence exists to demonstrate the benefits of exercise for patients recovering from stem-cell transplantation, and prehabilitation-exercise before treatment-has been shown to be effective in other disease areas. To date there has been no research into prehabilitation in patients with myeloma awaiting transplantation treatment.Our objective is to determine whether it is feasible to conduct a randomised controlled trial into pretransplant exercise for patients with multiple myeloma who are awaiting autologous stem-cell transplantation. METHODS AND ANALYSIS This mixed methods study identifies patients with diagnosis of multiple myeloma who have been assigned to the autologous transplantation list and invites them to participate in six weekly sessions of individualised, supervised exercise while awaiting transplantation.Quantitative data to determine feasibility targets include rates of recruitment, adherence and adverse events, and outcome measures including 6 min walking distance test and quality of life.Qualitative interviews are undertaken with a purposive sample of patients to capture their experiences of the study and the intervention. ETHICS AND DISSEMINATION Ethics committee approval has been obtained. Dissemination will be through open-access publications and presentations and will seek to reach multiprofessional bases as well as patients and carer groups, addressing the widespread interest in this area of research. TRIAL REGISTRATION NUMBER NCT03135925; Pre-results.

Abstract
INTRODUCTION Guidelines provide recommendations on the management of multiple myeloma (MM), but there are no standard algorithms for the choice and sequencing of treatments. As a result, there is widespread variation in the interpretation and implementation of these guidelines. Areas covered: This review will cover: the real-world data on MM treatment patterns; the approved agents available for the treatment of MM; a comparative summary of the national and international clinical guidelines; a discussion on the impact reimbursement decisions have on treatment availability. Expert commentary: In the future, treatment choices may become even more complex as clonal heterogeneity is better understood in the context of response to treatment, and next-generation agents become available. Although information on real-world practice patterns can provide further guidance, to date, few studies have generated data on patients treated with the newer agents in real-world settings. Furthermore, the translation of guideline recommendations into clinical practice across Europe is inconsistent. Additional real-world data are therefore vital to understanding current clinical practice patterns, so that new agents can be effectively incorporated into existing treatment strategies. Such information may aid the development of better guidance, which will ultimately help to ensure that patients receive the best possible care.

Abstract
We describe an unusual case of a biclonal nodal plasma cell dyscrasia, presenting with a vasculitic rash, end-organ damage, and cytopenias. Serum protein electrophoresis demonstrated a biclonal kappa-restricted paraprotein, with a negative skeletal survey and no bone marrow disease. Fluorodeoxyglucose-PET-CT (FDG-PET-CT) revealed nodal involvement, which was not appreciable clinically, and facilitated biopsy, confirming the diagnosis of a nodal plasmacytoma. Complete biochemical response and resolution of the vasculitic rash were achieved with bortezomib-based therapy.

Abstract
Multiple myeloma (MM) is an incurable plasma cell neoplasm with an incidence of 100 patients per year in Singapore. Major advances have been made in the diagnosis, risk stratification and treatment of MM in the recent past. The reclassification of a subset of patients with smouldering MM, based on high-risk biomarkers, and the development of the revised international staging system are among the key new developments in diagnosis and staging. The use of novel agent-based treatment has resulted in significant improvements in the survival and quality of life of many patients with MM. Determining the optimal use of proteasome inhibitors, immunomodulators and, more recently, monoclonal antibodies is an area of ongoing investigation. In this guideline, we aim to provide an overview of the management of MM, incorporating the latest developments in diagnosis and treatment.

Abstract
A growing population of long-term survivors of myeloma is now accumulating the 'late effects' not only of myeloma itself, but also of several lines of treatment given throughout the course of the disease. It is thus important to recognise the cumulative burden of the disease and treatment-related toxicity in both the stable and active phases of myeloma, some of which is unlikely to be detected by routine monitoring. We summarise here the evidence for the key late effects in long-term survivors of myeloma, including physical and psychosocial consequences (in Parts 1 and 2 respectively), and recommend the use of late-effects screening protocols in detection and intervention. The early recognition of late effects and effective management strategies should lead to an improvement in the management of myeloma patients, although evidence in this area is currently limited and further research is warranted.

Abstract
Recombinant mutant human tumor necrosis factor-related apoptosis-inducing ligand (rmhTRAIL) has become a potential therapeutic drug for multiple myeloma (MM). However, the exact targets and resistance mechanisms of rmhTRAIL on MM cells remain to be elucidated. The present study aimed to investigate the target and resistance-related proteins of rmhTRAIL on myeloma cell lines. A TRAIL-sensitive myeloma cell line, RPMI 8226, and a TRAIL-resistance one, U266, were chosen and the differentially expressed proteins between the two cell lines were analyzed prior and subsequent to rmhTRAIL administration by a liquid chromatography-tandem mass spectrometry method. The results showed that following TRAIL treatment, 6 apoptosis-related proteins, calpain small subunit 1 (CPNS1), peflin (PEF1), B-cell receptor-associated protein 31 (BAP31), apoptosis-associated speck-like protein containing CARD (ASC), BAG family molecular chaperone regulator 2 (BAG2) and chromobox protein homolog 3 (CBX3), were upregulated in RPMI 8226 cells while no change was identified in the U266 cells. Furthermore, small ubiquitin-related modifier 1 and several other ubiquitin proteasome pathway (UPP)-related proteins expressed higher levels in TRAIL-resistant cells U266 compared to the RPMI-8226 cells prior and subsequent to rmhTRAIL treatment. These results suggested that CPNS1, PEF1, BAP31, ASC, BAG2 and CBX3 were possibly target proteins of rmhTRAIL on RPMI 8226 cells, while UPP may have a vital role in mediating TRAIL-resistance in U266 cells.

Abstract
BACKGROUND Despite advances in the treatment of multiple myeloma (MM), it remains an incurable malignant disease. Myeloma genetics is intrinsically complex, but it offers an opportunity to categorize the disease and apply a personalized medicine approach. AREAS OF AGREEMENT Research into the genetics of myeloma is moving at a fast pace and is highlighting areas and patient cohorts likely to benefit from specific treatment. Targeting residual disease is likely to be crucial to improved clinical outcome. AREAS OF CONTROVERSY Patients in clinical trials are more likely to receive genetic diagnosis than non-trial patients, for whom access is ad hoc and dependent upon regional commissioning arrangements. AREAS TIMELY FOR DEVELOPING RESEARCH Relating genetics to potential treatment pathways will become crucial for improved myeloma outcomes. Universal access to standardized genetic testing will facilitate modern personalized treatments.
