Daratumumab más bortezomib más dexametasona en personas mayores de 18 años con diagnóstico de mieloma múltiple refractario a lenalidomida y con recaída a al menos una línea de terapia previa / Daratumumab plus bortezomib plus dexamethasone in people aged 18 years or older with a diagnosis of lenalidomide-refractory multiple myeloma and relapsed to at least one prior line of therapy

INTRODUCCIÓN: Cuadro clínico: El mieloma múltiple (MM) produce diversas manifestaciones clínicas como lesiones y fracturas óseas, insuficiencia renal, hipercalcemia, infecciones recurrentes y/o anemia. Esta condición representa uno de los cánceres hematológicos más frecuentes, con una incidencia estandarizada por edad de 1.92 por cada cien mil personas a nivel mundial. En Perú, el MM es el tercer cáncer hematológico más frecuente y con mayor mortalidad. Asimismo, se estima responsable de la pérdida de 5365 años de vida saludable al año, principalmente por su componente de muerte prematura. Tecnología sanitária: El daratumumab es un anticuerpo monoclonal que se une a la proteína CD38, expresada en alto nivel en las células tumorales del MM. Se encuentra indicado para uso combinado con bortezomib y dexametasona (D-Vd) en pacientes con MM tratados con al menos una línea de terapia previa. La dosis recomendada es 16 mg/kg de peso, administrados en ciclos semanales durante las primeras nueve semanas, cada tres semanas entre las semanas 10 y 24, y cada cuatro semanas a pa

Assessment of prolonged proteasome inhibition through ixazomib-based oral regimen on newly diagnosed and first-relapsed multiple myeloma: A real-world Chinese cohort study.

OBJECTIVE: To evaluate the effectiveness, safety, and convenience of in-class transition (iCT) from intravenous bortezomib-based induction to ixazomib-based oral regimens. METHODS: This retrospective real-world study was conducted in 16 Chinese hospitals between October 2017 and April 2023 and analyzed newly diagnosed (NDMM) and first-line relapsed multiple myeloma (FRMM) patients who attained at least a partial response from bortezomib-based induction therapy, followed by an ixazomib-based oral regimen for 2 year or until disease progression or intolerable toxicity. RESULTS: The study enrolled 199 patients, median age: 63 years old, male 55.4%, 53% as high risk (HR), and 47% as standard risk. Cytogenetic risk stratification by metaphase fluorescence in situ hybridization (M-FISH), based on the Mayo Clinic risk stratification system. The median duration of total PI therapy was 11 months, with ixazomib-based treatment spanning 6 months. At the 20-month median follow-up, 53% of patients remained on therapy. The 24-month PFS rate was 84.3% from the initiation of bortezomib-based induction and 83.4% from the start of ixazomib-based treatment. Overall response rate (ORR) was 100% post-bortezomib induction and 90% following 6 cycles of the ixazomib-based regimen. Based on the Sankey diagrams, 89.51% of patients maintained or improved their disease response after 2 cycles of iCT, 6 cycles (90.14%), and 12 cycles (80%). The HR level of Mayo was found to be a significant independent factor in a worse remission (hazard ratio (HR) 2.55; p = 0.033). Ixazomib's safety profile aligned with previous clinical trial data, with 49% of patients experiencing at least one AE of any grade. The most common AEs included peripheral neuropathy, nausea and vomiting, diarrhea, thrombocytopenia, and granulocytopenia. CONCLUSION: In the real-world Chinese MM population, NDMM and FRMM patients responded favorably to PI-based continuous therapy, demonstrating substantial response rates. The ixazomib-based iCT allows for sustained PI-based treatment, offering promising efficacy and tolerable AEs.

Cost-Effectiveness of Novel Agent Regimens for Transplant-Eligible Newly Diagnosed Multiple Myeloma Patients in India.

BACKGROUND: Survival outcomes for multiple myeloma have improved dramatically since the introduction of novel therapeutic agents. While these drugs are highly effective in improving survival outcomes and quality of life in patients with multiple myeloma, they come at a significant cost. We assessed the cost-effectiveness of bortezomib-based triplet or quadruplet drug regimens in isolation and followed by autologous hematopoietic stem cell transplantation (AHSCT) for the treatment of newly diagnosed multiple myeloma (NDMM) in the Indian context. METHODS: A Markov model was developed to assess the health and economic outcomes of novel drug regimens with and without AHSCT for the treatment of NDMM in India. We estimated the lifetime quality-adjusted life-years (QALYs) and costs in each scenario. The incremental cost-effectiveness ratios (ICERs) were computed and compared against the current willingness-to-pay threshold of a one-time per capita gross domestic product of ₹146,890 (US$1,927.70) for India. Parameter uncertainty was assessed through Monte Carlo probabilistic sensitivity analysis. RESULTS: Among seven treatment sequences, the VCd (bortezomib, cyclophosphamide, dexamethasone) alone arm has the lowest cost and health benefits as compared to four treatment sequences, namely VTd (bortezomib, thalidomide, dexamethasone) alone, VRd (bortezomib, lenalidomide, dexamethasone) alone, VRd plus AHSCT and DVRd (Daratumumab, bortezomib, lenalidomide, dexamethasone) plus AHSCT. It was found that VTd plus AHSCT and VCd plus AHSCT arms were extendedly dominated (ED) by combination of two alternative treatments. Among the five non-dominated strategies, VRd has a lowest incremental cost of ₹ 2,20,093 (US$2,888) per QALY gained compared to VTd alone followed by VRd plus AHSCT [₹3,14,530 (US$4,128) per QALY gained] in comparison to VRd alone. None of the novel treatment sequences were found to be cost-effective at the current WTP threshold of ₹1,46,890 (US$1,927.7). CONCLUSION: At the current WTP threshold of one-time per capita GDP (₹ 146,890) of India, VRd alone and VRd plus AHSCT has 38.1% and 6.9% probability to be cost-effective, respectively. Reduction in current reimbursement rates of novel drugs, namely VRd, lenalidomide, and pomalidomide plus dexamethasone under national insurance program and societal cost of transplant by 50%, would make VRd plus AHSCT and VTd plus AHSCT cost-effective at an incremental cost of ₹40,671 (US$34) and ₹97,639 (US$1,281) per QALY gained, respectively.

Treatment Pattern and Outcome of Newly Diagnosed Multiple Myeloma Patients in a Resource-Limited Setting.

BACKGROUND: Multiple myeloma is the third most common hematologic malignancy in Malaysia. The introduction of novel agents over the past decades has improved patient outcome and survival substantially. However, these agents incur significant economic burden, thus leading to limited use in less developed countries. This study aims to report on the real-world treatment pattern and outcome of newly diagnosed multiple myeloma (NDMM) patients from a resource-constraint setting. METHODS: This is a retrospective study on NDMM patients diagnosed between 1 January 2008 and 31 December 2022 in a single academic center. Patients' demographic and treatment details were included for analysis of progression free survival (PFS) and overall survival (OS). RESULTS: One hundred and thirty-six NDMM patients with a median age of 64.0 years (ranged from 38 to 87 years old) were included. Bortezomib-containing regimens were the most commonly used induction agent, followed by thalidomide. Almost half of the patients (47.1%) achieved very good partial response (VGPR) or complete remission (CR), while 31.6% achieved partial response (PR). Bortezomib containing regimen was associated with significantly deeper and more rapid response, (p=0.001 and p=0.017, respectively) when compared to other agents. Only 22.8% of these patients proceeded to upfront autologous haematopoietic stem cell transplantation.  The median OS and PFS were 60.0 months and 25.0 months, respectively. Best initial response and upfront autologous stem cell transplantation (ASCT) were significantly associated with better PFS. CONCLUSION: Achieving at least a VGPR significantly associated with better outcome in NDMM patients. In a resource constrain country, we recommend incorporating bortezomib in the induction therapy followed with an upfront ASCT.

The cost of multiple myeloma and its complications: A single-center study from Oran, Algeria.

BACKGROUND: The expenses of multiple myeloma (MM) represent a real economic and societal burden for patients and health authorities. However, very little is known about the situation in Algeria. Therefore, the aim of this study is to evaluate the costs generated by the management of MM and its complications in Algerian patients. MATERIALS AND METHODS: An observational retrospective study conducted on patients diagnosed with MM, from January 1st, 2019 to April 31st, 2023, at the Establishment Hospitalier Universitaire November 1st, Oran. A bottom-up costing methodology was used to assess the phase-specific cost and the complication burden. RESULTS: In total, 249 qualified for the study. For autologous stem cell transplantation (ASCT) eligible patients, the mean per patient cost of treating myeloma was estimated at: induction regimen ($4072); ASCT ($2899); consolidation ($1538); and maintenance ($355.76). The mean drug cost for ASCT-ineligible patients was $1421. The use of generic bortezomib and generic melphalan has led to a reduction in expenses of $1,075,181 ($5,024 per patient; 55.35%) and $10,864 ($487 per patient; 15.07%), respectively. Another cost-saving adaptation was ASCT using non-cryopreserved (NC) stem cells. The cost of managing MM complications was $177,782 per year. CONCLUSION: A number of adjustments have been implemented to the management of MM over time to improve clinical efficacy and reduce costs in Algeria. However, this may have come with a startlingly high cost of complications.

A Phase II Study to Evaluate the Efficacy of Bortezomib in Combination with Thalidomide in Treatment-Naïve Waldenstrom Macroglobulinemia Patients.

PURPOSE: Despite the recent success of Bruton's tyrosine kinase (BTK) inhibitors for the treatment of Waldenstrom macroglobulinemia (WM), their indefinite treatment duration ultimately tantamount to substantial financial and emotional burden. On the other hand, fixed duration of proteasome inhibitors (PI) have shown rapid and reasonable response in WM treatment. Despite the well-known synergism between PI and immunomodulatory drugs (IMiD), there is no trials evaluating such combination in WM. MATERIALS AND METHODS: Based on above, we designed this phase II study to investigate the efficacy and safety of 6 cycles of 28-day bortezomib-thalidomide-dexamethasone (VTD) regimen for treatment-naïve WM. RESULTS: A total of 15 patients were enrolled: major response rate was 64.3%, and overall response rate was 78.6%. During the median follow-up of 41 months, median progression-free survival (PFS) was 13 months and overall survival 40 months. For responders, median duration of response was 13 months and median PFS 19 months. The most common adverse event (AE) of any grade was constipation (57.1%). The most common grade ≥ 3 AE was anemia (21.4%). CONCLUSION: All in all, we hereby provide proof-of-concept that PI + IMiD may be an attractive backbone for fixed duration treatment. It should be noted that granting the same level of access to newer drugs globally is virtually impossible. Thus efforts to develop regimens using readily available drugs to yield similar or adequate treatment outcomes should not be disregarded. In this sense, we believe our study holds its place for its novelty and eloquently addresses achieving the daunting societal quest of health equity.

Adding a Gene Expression Profile Test to Aid Differential Diagnosis and Treatment in Aggressive Large B-Cell Lymphoma: An Early Exploratory Economic Evaluation.

BACKGROUND AND OBJECTIVE: Adding gene expression profiles (GEPs) to the current diagnostic work-up of aggressive large B-cell lymphomas may lead to the reclassification of patients, treatment changes and improved outcomes. A GEP test is in development using TempO-Seq® technology to distinguish Burkitt lymphoma (BL) and primary mediastinal large B-cell lymphoma (PMBCL) from diffuse large B-cell lymphoma (DLBCL), and to classify patients with DLBLC and to predict the benefit of (e.g.) adding bortezomib to R-CHOP therapy (RB-CHOP). This study aims to estimate the potential impact of a GEP test on costs and health outcomes to inform pricing and evidence generation strategies. METHODS: Three decision models were developed comparing diagnostic strategies with and without GEP signatures over a lifetime horizon using a UK health and social care perspective. Inputs were taken from a recent clinical trial, literature and expert opinion. We estimated the maximum price of the test using a threshold of Great Britain Pound (GBP) 30,000 per quality-adjusted life-year (QALY). Sensitivity analyses were conducted. RESULTS: The estimated maximum threshold price for a combined test to be cost effective is GBP 15,352. At base-case values, the BL signature delivers QALY gains of 0.054 at an additional cost of GBP 275. This results in a net monetary benefit at a threshold of GBP 30,000 per QALY of GBP 1345. For PMBCL, the QALY gain was 0.0011 at a cost saving of GBP 406 and the net monetary benefit was GBP 437. The hazard ratio for the impact of treating BL less intensively must be at least 1.2 for a positive net monetary benefit. For identifying patients with the DLBCL subtype responsive to bortezomib, QALY gain was 0.2465 at a cost saving of GBP 6175, resulting in a net monetary benefit of GBP 13,570. In a probabilistic sensitivity analysis using 1000 simulations, a testing strategy was superior to a treat all with R-CHOP strategy in 81% of the simulations and with a cost saving in 92% assuming a cost price of zero. CONCLUSIONS: Our estimates show that the combined test has a high probability of being cost effective. There is good quality evidence for the benefit of subtyping DLBCL but the evidence on the number of patients reclassified to or from BL and PMBCL and the impact of a more precise diagnosis and the cost of treatment is weak. The developers can use the price estimate to inform a return on investment calculations. Evidence will be required of how well the TempO-Seq® technology performs compared to the testing GEP technology used for subtyping in the recent clinical trial. For BL and PMBCL elements of the test, evidence would be required of the number of patients reclassified and improved costing information would be useful. The diagnostic and therapeutic environment in haematological malignancies is fast moving, which increases the risk for developers of diagnostic tests.

NK92 Expressing Anti-BCMA CAR and Secreted TRAIL for the Treatment of Multiple Myeloma: Preliminary In Vitro Assessment.

Multiple myeloma (MM) has witnessed improved patient outcomes through advancements in therapeutic approaches. Notably, allogeneic stem cell transplantation, proteasome inhibitors, immunomodulatory drugs, and monoclonal antibodies have contributed to enhanced quality of life. Recently, a promising avenue has emerged with chimeric antigen receptor (CAR) T cells targeting B-cell maturation antigen (BCMA), expressed widely on MM cells. To mitigate risks associated with allogenic T cells, we investigated the potential of BCMA CAR expression in natural killer cells (NKs), known for potent cytotoxicity and minimal side effects. Using the NK-92 cell line, we co-expressed BCMA CAR and soluble tumor necrosis factor-related apoptosis-inducing ligand (sTRAIL) employing the piggyBac transposon system. Engineered NK cells (CAR-NK-92-TRAIL) demonstrated robust cytotoxicity against a panel of MM cell lines and primary patient samples, outperforming unmodified NK-92 cells with a mean difference in viability of 45.1% (±26.1%, depending on the target cell line). Combination therapy was explored with the proteasome inhibitor bortezomib (BZ) and γ-secretase inhibitors (GSIs), leading to a significant synergistic effect in combination with CAR-NK-92-TRAIL cells. This synergy was evident in cytotoxicity assays where a notable decrease in MM cell viability was observed in combinatorial therapy compared to single treatment. In summary, our study demonstrates the therapeutic potential of the CAR-NK-92-TRAIL cells for the treatment of MM. The synergistic impact of combining these engineered NK cells with BZ and GSI supports further development of allogeneic CAR-based products for effective MM therapy.

[Assessment of systemic inflammation activity, myocardial structure and functional features, their relationship in patients with multiple myeloma, receiving bortezomib therapy].

AIM: To study the dynamics of calculated indices [neutrophil-lymphocyte ratio (NLR); systemic inflammation index (SIV)] and biomarkers of systemic inflammation [interleukin-1ß (IL-1ß); high-sensitivity C-reactive protein (hsCRP)], parameters of the structure-and-function state of the myocardium and intracardiac hemodynamics, and their relationship in patients newly diagnosed with multiple myeloma (MM) at the onset of the disease and after 6 courses of chemotherapy (CT) containing the proteasome inhibitor bortezomib. MATERIAL AND METHODS: This prospective study included 30 patients aged 63.8±10.0 years diagnosed with MM; 17 (56.7 %) of them were men. The following tests were performed for all patients: measurement of IL-1ß and hsCRP, calculation of the inflammation indexes NLR and SIV, transthoracic echocardiography before and after 6 courses of bortezomib-containing CT. At the time of study completion, 9 patients dropped out due to reasons not related to cardiovascular complications of CT. RESULTS: The antitumor therapy was associated with increases of immune-inflammation indexes: NLR increased from 1.54 [1.02; 1.83] to 2.9 [1.9; 4.35] (p=0.009) and SIV increased from 402.95 [230.5; 534.0] to 1102.2 [453.1; 1307.9] (р=0.014). IL-1ß increased from 5.15 [4.05; 5.77] to 6.22 [5.66; 6.52] pg/ml remaining within the reference range (p=0.142) whereas hsCRP decreased from 1.02 [0.02; 2.71] to 0.02 [0.02; 0.82] IU/l (p=0.138). Statistically significant changes in parameters of heart remodeling and clinical picture of cardiovascular complications were not observed. A correlation analysis showed significant inverse correlations of hsCRP with left ventricular ejection fraction (LV EF) (r= -0.557; p=0.003), the number of plasma cells (PC) with LV EF (r= -0.443; p=0.023), and a direct correlation of the number of PC with hsCRP (r=0.433; p=0.022). CONCLUSION: During the study, the accepted criteria for cardiotoxicity of bortezomib-containing chemotherapy in patients with MM, were not met. The identified correlations between the level of markers for acute inflammation, indexes of intracardiac hemodynamics, and the immediate MM substrate may indicate the role of chronic low-intensity inflammation in the pathogenesis of myocardial remodeling in patients with MM. This necessitates further studies on larger samples of patients to assess the prognostic significance.

Daratumumabe em combinação com bortezomibe e dexametasona para o tratamento de pacientes com mieloma múltiplo recidivado e/ou refratário que receberam uma única terapia prévia no Sistema Único de Saúde (SUS) / Daratumumab in combination with bortezomib and dexamethasone for the treatment of patients with relapsed and/or refractory multiple myeloma who have received a single prior therapy in the Unified Health System (SUS)

INTRODUÇÃO: O mieloma múltiplo (MM) é uma neoplasia maligna, caracterizada pela proliferação desregulada de plasmócitos (responsáveis pela produção de anticorpos), resultando principalmente em produção exacerbada de imunoglobulina não funcional. As manifestações clínicas mais comuns são dores ósseas e fraturas, anemia, insuficiência renal e infecções recorrentes. É a segunda neoplasia hematológica mais frequente (10-15% dos casos) e representa 1% de todos os tumores malignos, sendo considerada uma doença progressiva e sem cura, com a maioria dos pacientes apresentando múltiplas remissões e recidivas. O manejo terapêutico de MM recidivado e /ou refratário (MMRR) ainda é um desafio devido ao aumento da resistência às terapias, piora do prognóstico e declínio da qualidade de vida desses pacientes conforme progridem nas linhas de tratamento. HISTÓRICO DE RECOMENDAÇÕES DA CONITEC: Em fevereiro de 2022 foi publicado o Relatório de Recomendação nº 702 analisando o uso de daratumumabe para o controle do MMRR. A recomendação da Conitec e decisão do Ministério da Saúde foi pela não incorporação no SUS, considerando os indicadores de eficiência apresentados e a estimativa elevada de impacto orçamentário. Diferente da demanda de 2022, a solicitação atual, propõe o uso de daratumumabe em associação com bortezomibe e dexametasona apenas para pacientes com MMRR que receberam uma única terapia prévia. PE

Survival outcomes among patients with multiple myeloma in the era of novel agents: exploratory assessment using an electronic medical record database in Japan.

Despite recent advances in the range of therapies available for the treatment of multiple myeloma (MM), there are limited data surrounding survival outcomes and baseline characteristics influencing survival in general clinical practice in Japan. The aim of this study was to use electronic medical records (EMRs) to examine overall survival (OS) and prognostic factors in Japanese patients with MM. We extracted EMRs in the Real World Data (RWD) database of patients with a confirmed diagnosis of MM and treatment history with bortezomib, thalidomide, and/or lenalidomide. OS and prognostic factors for OS were analyzed using a univariate analysis and decision tree model. Of the 6509 patients in the database with a diagnosis of MM, 1565 were eligible. Patients had a median (range) age of 72 (23-92) years, a median OS of 53.5 months, and a 5-year OS rate of 45.6%. In alignment with previous studies, International Staging System stage and age were prognostic of OS. In addition, platelet and erythrocyte counts, chloride, total protein, C-reactive protein, and lactate dehydrogenase levels were identified as important prognostic factors for OS and were used to pilot a simple prognostic tool. In conclusion, we found that the survival outcomes extracted from EMRs in the RWD of Japanese patients with MM aligned with a previous retrospective study from Japan. Baseline laboratory parameters prognostic for OS were explored with additional factors to International Staging System and age identified. These might be used to optimize treatment selection, although further investigation using additional data sources is required.

Development and Characterization of a 96-Well Exposure System for Safety Assessment of Nanomaterials.

In this study, a 96-well exposure system for safety assessment of nanomaterials is developed and characterized using an air-liquid interface lung epithelial model. This system is designed for sequential nebulization. Distribution studies verify the reproducible distribution over all 96 wells, with lower insert-to-insert variability compared to non-sequential application. With a first set of chemicals (TritonX), drugs (Bortezomib), and nanomaterials (silver nanoparticles and (non-)fluorescent crystalline nanocellulose), sequential exposure studies are performed with human lung epithelial cells followed by quantification of the deposited mass and of cell viability. The developed exposure system offers for the first time the possibility of exposing an air-liquid interface model in a 96-well format, resulting in high-throughput rates, combined with the feature for sequential dosing. This exposure system allows the possibility of creating dose-response curves resulting in the generation of more reliable cell-based assay data for many types of applications, such as safety analysis. In addition to chemicals and drugs, nanomaterials with spherical shapes, but also morphologically more complex nanostructures can be exposed sequentially with high efficiency. This allows new perspectives on in vivo-like and animal-free approaches for chemical and pharmaceutical safety assessment, in line with the 3R principle of replacing and reducing animal experiments.

Real-world treatment patterns, costs, and outcomes in patients with AL amyloidosis: analysis of the Optum EHR and commercial claims databases.

BACKGROUND: This study characterised real-world treatment patterns, clinical outcomes, and cost-of-illness in patients with light-chain (AL) amyloidosis. METHODS: Data were extracted from the US-based Optum® EHR and Clinformatics® Data Mart (claims) databases (2008-2019) for patients newly diagnosed with AL amyloidosis and who initiated anti-plasma cell therapies. Healthcare resource utilisation (HCRU) and related costs were compared across lines of therapy (LOT). Incidences of cardiac and renal failure were evaluated using the Kaplan-Meier method. RESULTS: About 1347 patients (EHR, n = 776; claims, n = 571) were included. Median age was 68 years; 56.8% were male. At initial diagnosis, 33.1% and 15.1% of patients had cardiac and renal failure, respectively. Most patients received bortezomib-containing treatment in LOT1 (69%); bortezomib-cyclophosphamide-dexamethasone was most common (26%). HCRU was similar across LOTs. Mean per-patient-per-month and per-patient-per-LOT costs were $19,343 and $105,944 for LOT1, $19,183 and $95,793 for LOT2, and $16,611 and $128,446 for LOT3, respectively. Costs were primarily driven by anti-plasma cell therapies, outpatient visits, and hospitalisations. The 5-year cardiac and renal failure rates following initial diagnosis were 64.5% and 39.0%, respectively. CONCLUSION: AL amyloidosis is associated with substantial costs and suboptimal outcomes, highlighting the need for new therapeutic approaches to prevent organ deterioration, and reduce disease burden.

Budget Impact Analysis of Idecabtagene Vicleucel for the Treatment of Adult Patients with Relapsed or Refractory Multiple Myeloma in the US.

BACKGROUND: Gene therapy is known to be unaffordable to those who need it the most; however, evidence on the financial impact is limited. OBJECTIVE: This study aimed to estimate the budget impact and affordability of the gene therapy idecabtagene vicleucel for the treatment of adult patients with relapsed or refractory multiple myeloma (rrMM) in the US over a 3-year period from the payer healthcare perspective. METHOD: A budget impact model was developed to estimate the budget impact to the US healthcare plan compared with bortezomib-based maintenance therapy. The target population size was based on a hypothetical 1-million-member plan over a 3-year time horizon with and without idecabtagene vicleucel adoption. The cost of drug acquisition, drug administration, and grade 3-4 adverse events (AEs) were calculated for both scenarios. The budget impact of idecabtagene vicleucel was calculated as the difference in costs for these two scenarios. Costs were extracted from IBM-Micromedex Red Book, Centers for Medicare and Medicaid Services, and the literature. A one-way sensitivity analysis was performed to ensure robustness. RESULTS: An estimated 22 patients with rrMM each year would be eligible for idecabtagene vicleucel. The model projected the annual cost per patient in the first year as $19,449 and $517,528.13 for bortezomib and idecabtagene vicleucel, respectively. Introducing idecabtagene vicleucel was predicted to increase the total budget by $13.4, $13.6, and $14 million in the first, second, and third years. There would be an additional $1.1128, $1.1252, and $1.1486 per member per month (PMPM) when using idecabtagene vicleucel over bortezomib. CONCLUSION: This study suggests that the high cost of the gene therapy idecabtagene vicleucel is justifiable due to the low number of rrMM patients.

Carfilzomibe no tratamento de pacientes com mieloma múltiplo recidivado ou refratário, que receberam terapia prévia / Carfilzomib in the treatment of patients with relapsed or refractory multiple myeloma who have received prior therapy

INTRODUÇÃO: O mieloma múltiplo (MM) é uma neoplasia hematológica maligna caracterizada pela proliferação descontrolada de plasmócitos alterados na medula óssea, resultando na produção aumentada de imunoglobulinas não funcional (proteína monoclonal). O acúmulo destas imunoglobulinas e a interação dos plasmócitos com outras células da medula óssea resultam em anemia, lesões ósseas, infecções, hipercalcemia, injúria renal, fadiga e dor. A incidência mundial informada pelo Globocan é de 2,2 novos casos por 100.000 habitantes em homens e 1,5/100.000 em mulheres, com ocorrência, a nível mundial, de 176 mil novos casos e 117 mil mortes em 2020. Carfilzomibe é um agente antineoplásico, inibidor de proteassoma que se liga seletiva e irreversivelmente nos sítios ativos. Tem atividade antiproliferativa e pró-apoptóticas. PERGUNTA DE PESQUISA: Kyprolis® (carfilzomibe) em combinação com dexametasona é eficaz e seguro no tratamento de pacientes com mieloma múltiplo recidivado ou refratário que receberam uma terapia prévia quando em comparação a bortezomibe, ciclofosfamida, dexametasona, cisplatina, doxorrubicina, doxorrubicina lipossomal, etoposídeo, melfalana, vincristina ou talidomida? EVIDÊNCIAS CLÍNICAS: O demandante realizou as buscas na literatura utilizando as seguintes bases de dados: The Cochrane Library, Medline via PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Centre for Reviews and Dissemination (CRD), o que resultou na inclusão de 14 publicações. Na análise conduzida pela Secretaria Executiva foram consideradas 12 publicações referentes a um ensaio clínico randomizado e uma publicação de revisão sistemática. O estudo ENDEAVOR foi um ensaio clínico de fase III, multicêntrico, aberto, que incluiu 929 participantes randomizados para receber carfilzomibe+dexametasona ou bortezomibe+dexametasona. A mediana de SLP foi 18,7 meses (IC 95%, 15,6 a não estimável) no grupo que recebeu carfilzomibe comparado a 9,4 meses (IC 95%, 8,4 a 10,4) no grupo que recebeu bortezomibe, resultando em uma magnitude de benefício absoluto de 9,3 meses (HR 0,53 [IC95% 0,44 a 0,65]; p< 0,0001). A duração mediana de resposta foi 21,3 meses (IC95% 21,3 a não estimável) no grupo carfilzomibe e 10,4 meses (IC95% 9,3 a 13,8) no grupo bortezomibe. Em ambos os grupos, 98% dos participantes apresentaram eventos adversos (qualquer grau), sendo a anemia (43% versus 28%), diarreia (36,7% versus 40,6%) e febre (32,6% versus 15,4%) os eventos mais frequentes nos grupos carfilzomibe e bortezomibe, respectivamente. Os eventos adversos mais comuns grau 3 ou maior foram reportados em 81,9% dos participantes do grupo carfilzomibe (n=379) e 71,1% no grupo bortezomibe (n=324), sendo a anemia (17,3% no grupo carfilzomibe e 10,1% no grupo bortezomibe), hipertensão (14,9% versus 3,3%), trombocitopenia (12,5% versus 14,7%),os três eventos mais frequentes. Insuficiência cardíaca grau 3 ou superior, foi mais frequente no grupo carfilzomibe (6%) que no grupo bortezomibe (2%.). AVALIAÇÃO ECONÔMICA: O demandante apresentou uma análise de custo-efetividade. Na análise do cenário base, em um horizonte temporal de 30 anos, carfilzomibe acrescentou ganhos incrementais de 1,19 QALY, resultando em uma razão de custo utilidade incremental (RCEI) de R$ 195.310,00 por QALY. No cenário proposto pela Secretária-Executiva (horizonte temporal de 10 anos e valor de utilidade derivada do estudo ENDEAVOR), carfilzomibe gerou benefício de 0,63 QALY, com RCEI de R$ 365.830,00 por QALY. ANÁLISE DE IMPACTO ORÇAMENTÁRIO: Com o desconto apresentado pelo demandante, a incorporação de carfilzomibe ao SUS implica em custos adicionais ao sistema de saúde no montante de aproximadamente R$ 365 milhões em cinco anos. A principal limitação da análise foi a estimativa da população. MONITORAMENTO DO HORIZONTE TECNOLÓGICO: Foram identificadas 10 tecnologias potenciais para compor o esquema terapêutico de pacientes adultos com mieloma múltiplo recidivado ou refratário: Belantamabe mafodotin, Ciltacabtageno autoleucel, Elranatamab, Iberdomida, Idecabtagene vicleucel, Isatuximabe, nivolumabe, selinexor, teclistamab, venetoclax. Tais medicamentos são anticorpo monoclonal ligado a um antineoplásico, anticorpo biespecífico, anticorpo monoclonal, imumodulador, terapias baseadas em células T autólogas geneticamente modificadas (CAR-T), inibidor SINE, ou inibidor de Bcl-2. A maioria não possui registro na FDA, EMA ou Anvisa. CONSIDERAÇÕES FINAIS: Os resultados sugerem eficácia e segurança do carfilzomibe na população elegível, porém, no horizonte temporal de 10 anos, com QALY < 1, RCEI de R$ 365.830,00 por QALY e impacto orçamentário de aproximadamente R$ 17 milhões no primeiro ano de incorporação e R$ 131 milhões no 5º ano da incorporação, totalizando R$ 365 milhões em cinco anos. RECOMENDAÇÃO PRELIMINAR DA CONITEC: Os membros do Plenário presentes na 109ª Reunião Ordinária da Conitec, realizada no dia 08 de junho de 2022, sem nenhuma declaração de conflito de interesse, deliberaram por unanimidade, encaminhar o tema para consulta pública com recomendação preliminar desfavorável à incorporação de carfilzomibe para o tratamento de mieloma múltiplo recidivado ou refratário no SUS. Os membros consideraram a evidência científica boa e favorável ao carfilzomibe, porém, a RCEI e o impacto orçamentário foram considerados muito altos para o tratamento de uma doença que já tem outras opções terapêuticas disponíveis no SUS. CONSULTA PÚBLICA: Entre os dias 08/07/2022 e 27/07/2022 foram recebidas 421 contribuições, sendo 152 pelo formulário para contribuições técnico-científicas e 269 pelo formulário para contribuições sobre experiência ou opinião de pacientes, familiares, amigos ou cuidadores de pacientes, profissionais de saúde ou pessoas interessadas no tema. A maioria foi a favor da incorporação de carfilzomibe no SUS (97% via formulário técnico-científico e 100%). O principal benefício apontado nas contribuições técnico-científicas foi sobre a eficácia, aumento da sobrevida e qualidade de vida, além da disponibilidade de mais uma opção terapêutica e promoção da igualdade no tratamento nos sistemas público e privado de saúde. A empresa detentora do registro do medicamento atualizou o preço do medicamento, e consequentemente os valores do impacto orçamentário e avaliação econômica. No impacto orçamentário o valor ficou em R$ 95,3 milhões em cinco anos. Nas contribuições de experiência e opinião, a totalidade dos respondentes discordou da recomendação preliminar da Conitec. No âmbito das opiniões e experiências positivas, foi mencionada a necessidade de garantir o acesso ao carfilzomibe, especialmente por representar uma alternativa para pacientes recidivados e refratários. Também foi citada a eficácia da tecnologia. Como dificuldades, destacou-se a falta de acesso pelo SUS. Em relação a outros medicamentos, foram mencionados benefícios, mas, também, a eficácia limitada no caso de pacientes recidivados. RECOMENDAÇÃO FINAL DA CONITEC: Os membros do Plenário da Conitec, em sua 112ª Reunião Ordinária, realizada no dia 31 de agosto de 2022, deliberaram por maioria simples, recomendar a não incorporação no SUS de carfilzomibe para o tratamento de pacientes com mieloma múltiplo recidivado ou refratário, que receberam terapia prévia, no SUS. Não houve apresentação de dados clínicos adicionais. Com o preço do medicamento atualizado, ainda assim não se mostrou custo-efetivo. Foi assinado o Registro de Deliberação nº 765/2022. DECISÃO: Não incorporar, no âmbito do Sistema Único de Saúde - SUS, o carfilzomibe para o tratamento de pacientes com mieloma múltiplo recidivado ou refratário, conforme a Portaria nº 107, publicada no Diário Oficial da União nº 184, seção 1, página 75, em 27 de setembro de 2022.

Usability of German hospital administrative claims data for healthcare research: General assessment and use case of multiple myeloma in Munich university hospital in 2015-2017.

OBJECTIVES: To assess the usability of German hospital administrative claims data (GHACD) to determine inpatient management patterns, healthcare resource utilization, and quality-of-care in patients with multiple myeloma (PwMM). METHODS: Based on German tertiary hospital's claims data (2015-2017), PwMM aged >18 years were included if they had an International Classification of Diseases, Tenth Revision, code of C90.0 or received anti-MM therapy. Subgroup analysis was performed on stem cell transplantation (SCT) patients. RESULTS: Of 230 PwMM, 59.1% were men; 56.1% were aged ≥65 years. Hypertension and infections were present in 50% and 67.0%, respectively. Seventy percent of PwMM received combination therapy. Innovative drugs such as bortezomib and lenalidomide were given to 36.1% and 10.9% of the patients, respectively. Mean number of admissions and mean hospitalization length/patient were 3.69 (standard deviation (SD) 2.71 (1-16)) and 12.52 (SD 9.55 (1-68.5)) days, respectively. In-hospital mortality was recorded in 12.2%. Seventy-two percent of SCT patients (n = 88) were aged ≤65 years, 22.7% required second transplantation, and 89.8% received platelet transfusion at a mean of 1.42(SD 0.63 (1-3)). CONCLUSION: GHACD provided relevant information essential for healthcare studies about PwMM from routine care settings. Data fundamental for quality-of-care assessment were also captured.

Daratumumab in first-line therapy is cost-effective in transplant-eligible patients with newly diagnosed myeloma.

Triplet regimens, such as lenalidomide, bortezomib, and dexamethasone (RVd) or thalidomide, bortezomib, and dexamethasone (VTd), are standard induction therapies for transplant-eligible patients with newly diagnosed multiple myeloma (NDMM). The addition of daratumumab to RVd and VTd has been investigated in the GRIFFIN and CASSIOPEIA trials, respectively, resulting in improvement in the rate of minimal residual disease (MRD) negativity. In this study, we conducted a cost-effectiveness analysis with a 10-year time horizon to compare first-line and second-line use of daratumumab for transplant-eligible patients with NDMM. Because long-term follow-up data for these clinical trials are not yet available, we developed a Markov model that uses MRD status to predict progression-free survival. Daratumumab was used either in the first-line setting in combination with RVd or VTd or in the second-line setting with carfilzomib plus dexamethasone (Kd). Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios were calculated from a Japanese and US payer perspective. In the Japanese analysis, D-RVd showed higher QALYs (5.43 vs 5.18) and lower costs (¥64 479,793 vs ¥71 287 569) compared with RVd, and D-VTd showed higher QALYs (5.67 vs 5.42) and lower costs (¥43 600 310 vs ¥49 471,941) compared with VTd. Similarly, the US analysis demonstrated dominance of a strategy incorporating daratumumab in first-line treatment regimens. Given that overall costs are reduced and outcomes are improved when daratumumab is used as part of a first-line regimen, the economic analysis indicates that addition of daratumumab to first-line RVd and VTd regimens is a dominant strategy compared with reserving its use for the second-line setting.

Clinical Observation and Pharmacoeconomic Evaluations of Original Research Drug and Generic Drug Bortezomib in the Treatment of Multiple Myeloma.

Background: Multiple myeloma (MM) is one of the hitherto incurable malignant blood tumors. Bortezomib plays an important role in the treatment of MM. Objective: We aimed to compare effectiveness, safety, and pharmacoeconomic evaluations of the original research drug and the generic drug Bortezomib in the treatment of MM, so as to provide a reasonable basis for the selection of drugs in clinical diagnosis and treatment. Methods: A collection of 374 patients with MM were diagnosed and treated with combined Bortezomib in our hospital from July 2019 to January 2020.Two hundred and sixty nine cases met the criteria for inclusion and discharge. According to the different drug manufacturers, divided into the original research drug group (n = 149) and the generic drug group (n = 120). The effectiveness and safety were separately counted, and use the cost-minimization analysis to make the pharmacoeconomic evaluations. Results: Compared with the results of the two groups, there was no statistical difference between the two groups of treatment efficacy or adverse reaction rates (P > 0.05). The average daily cost of the original research drug group was 2954.38 Chinese yuan (CNY), the average treatment cost per cycle was 32967.69 CNY, the average daily cost of the generic drug group was 2697.29 CNY, and the average treatment cost per cycle was 29129.57 CNY. The price of the generic drug group is lower than the original drug group, and there was a statistical difference between the two groups (P < 0.05). Conclusion: There was no difference between the two groups of effectiveness or safety, and the generic drug is more economical in the treatment.

Kinetics of response to first- and second-line therapies in multiple myeloma: Assessment by both M-spikes and light chains.

OBJECTIVES: The prognostic value of kinetics of response to multiple myeloma (MM) therapy is controversial. We aimed to expand the knowledge on this topic by reviewing the kinetics of response to both first- and second-line MM therapy, utilizing a homogeneously treated cohort and analyzing separately both M-spike and light chain (LC) responses for each patient. METHODS: We reviewed all patients who received first-line cyclophosphamide, bortezomib and dexamethasone induction followed by autologous transplant with melphalan and lenalidomide maintenance in our center between 2007 and 2019. RESULTS: Analyzing 360 patients, we observed no correlation between response kinetics to first- versus second-line therapy at the individual patient level. Time to best response to first-line therapy was not a predictor of outcome; however, longer time to best response was highly predictive of a favorable outcome in the second-line setting, independent of other factors. Patients with IgA-MM cleared their M-spike faster than IgG-MM, probably reflecting different half-lives of these isotypes rather than disease biology, as the clearance of LC in both subtypes was similar. CONCLUSIONS: Analyzing both M-spike and LC responses in a homogenously treated cohort, we identified important insights regarding the prognostic value of kinetic patterns. Prospective analysis may shed more light on unsolved questions.
