Tien FM, Hou HA. CEBPA mutations in acute myeloid leukemia: implications in risk stratification and treatment. Int J Hematol 2024:10.1007/s12185-024-03773-5. [PMID: 38671183 DOI: 10.1007/s12185-024-03773-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 04/02/2024] [Accepted: 04/08/2024] [Indexed: 04/28/2024]
Abstract
Mutations in CCAAT enhancer binding protein α (CEBPA) occur in approximately 10% of patients with de novo acute myeloid leukemia (AML). Emerging evidence supports that in-frame mutations in the basic leucine zipper domain of CEBPA (CEBPAbZIP-inf) confer a survival benefit, and CEBPAbZIP-inf replaced CEBPA double mutations (CEBPAdm) as a unique entity in the 2022 World Health Organization (WHO-2022) classification and International Consensus Classification (ICC). However, challenges remain in daily clinical practice since more than 30% patients with CEBPAbZIP-inf die of AML despite intensive treatment. This review aims to provide a comprehensive summary of the heterogeneities observed in AML with CEBPAdm and CEBPAbZIP-inf, and will discuss the prognostic implications of concurrent mutations and novel mechanistic targets that may inform future drug development. The ultimate goal is to optimize clinical management and to provide precision medicine for this category of patients.

Cost-Effectiveness of Blinatumomab in Pediatric Patients with High-Risk First-Relapse B-Cell Precursor Acute Lymphoblastic Leukemia in France. PHARMACOECONOMICS - OPEN 2023:10.1007/s41669-023-00411-4.

Abstract
BACKGROUND Based on the results of the phase III randomized 20120215 trial, the European Medicines Agency granted the approval of blinatumomab for the treatment of pediatric patients with high-risk first-relapsed Philadelphia chromosome-negative B-cell precursor acute lymphoblastic leukemia (ALL). In France, blinatumomab received reimbursement for this indication in May 2022. This analysis assessed the cost effectiveness of blinatumomab compared with high-risk consolidation chemotherapy (HC3) in this indication from a French healthcare and societal perspective. METHODS A partitioned survival model with three health states (event-free, post-event and death) was developed to estimate life-years (LYs), quality-adjusted life-years (QALYs) and costs over a lifetime horizon. Patients who were alive after 5 years were considered to be cured. An excess mortality rate was applied to capture the late effects of cancer therapy. Utility values were based on the TOWER trial using French tariffs, and cost input data were identified from French national public health sources. The model was validated by clinical experts. RESULTS Treatment with blinatumomab over HC3 was estimated to provide gains of 8.39 LYs and 7.16 QALYs. Total healthcare costs for blinatumomab and HC3 were estimated to be €154,326 and €102,028, respectively, resulting in an increment of €52,298. The incremental cost-effectiveness ratio was estimated to be €7308 per QALY gained from a healthcare perspective. Results were robust to sensitivity analyses, including analysis from the societal perspective. CONCLUSIONS Blinatumomab administered as part of consolidation therapy in pediatric patients with high-risk first-relapsed ALL is cost effective compared with HC3 from the French healthcare and societal perspective.

BMC Health Serv Res 2023; 23:36. [PMID: 36642712 PMCID: PMC9841690 DOI: 10.1186/s12913-023-09054-x] [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: 06/29/2022] [Accepted: 01/10/2023] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Based on the results from the ALFA-0701 study, gemtuzumab ozogamicin (GO) has been approved by the European Medicine Agency and by the Italian Drug Agency for the first line treatment of de novo acute-myeloid leukemia (AML). In this analysis, we assessed the cost-effectiveness of GO in combination with daunorubicin and cytarabine (DA), vs DA alone, adopting the perspective of the Italian National Health Service. METHODS For this analysis, a cohort state transition model was developed. The model was designed to capture health states and events that occur throughout the entire disease course and that impact costs and outcomes. The ALFA-0701 study was the main source of clinical data for this analysis. In the model, patients had the same baseline characteristics and experienced the same clinical improvements as in the ALFA-0701 study. Economic data (resource consumption and unit costs) were adapted to reflect expenditure for the Italian National Health Service. Utilities per health state and disutilities due to adverse events were based on the literature and on the general population for those functionally cured. A lifetime horizon was adopted, with both costs and outcome being discounted of 3.0%, annually. Deterministic and probabilistic sensitivity analyses were conducted to assess the robustness of results. RESULTS In the base case (lifetime horizon; primary source of data: study ALFA-0701; perspective: Italian National Health Service; discount rate on costs and outcomes: 3.0%), GO + DA was more effective DA both in terms of life-year (LY) survival (6.42 LY vs 5.75 LY, respectively) and quality-of-life adjusted survival (4.69 QALY vs 4.19 QALY, respectively). The overall costs were almost similar in the two groups (slightly lower with GO + DA than with DA; €162,424 and €162,708, respectively). The use of GO increased the costs of drug therapy but saved costs of relapse and costs associated with transplantation (HSCT). CONCLUSIONS If results of the ALFA-0701 study are applied to the Italian healthcare environment, then gemtuzumab ozogamicin, in combination with daunorubicin and cytarabine, would clinical outcomes and reduce lifetime costs, compared with daunorubicin and cytarabine alone for the first line treatment of de novo AML.

Abstract
Objective: To assess the cost-effectiveness and economic sustainability of treosulfan plus fludarabine compared with busulfan plus fludarabine as a conditioning treatment for malignant disease prior to allogeneic haematopoietic stem cell transplantation (alloHSCT) in adult patients in Italy. Method: The two theoretical cohorts of patients aged ≥ 60 years with acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) were pooled and followed over time using a partitioned survival model with cycles of 28 days. Patients can transition between a post-HSCT recovery/remission state (Event-Free Survival state, EFS state), a relapsed/progressed disease state, and a death state. A lifetime horizon for cost-effectiveness analysis and a 5-years’ time horizon for budget impact analysis were used. The perspective of the Italian National Health Service was adopted. Utility values were obtained from published sources. Costs included: drug acquisition, HSCT procedure, management and treatment of adverse reactions, graft-versus-host disease (GvHD) and health states, end of life treatment. Discounting of 3% per year was applied for both costs and outcomes according to Italian guidelines. Sensitivity was tested through both one-way and probabilistic analyses. Results: Cost-effectiveness analysis showed that treosulfan is both more effective and less expensive compared with busulfan (+1.08 life-years, +0.95 quality-adjusted life-years per patient and –€ 41,388 per patient). On the side of economic sustainability, the introduction of treosulfan in the market could generate a cumulative decrement of the expense incurred by NHS of about –€ 212,063 over five years. Conclusion: Treosulfan could represent a cost-effective and sustainable treatment alternative from the perspective of the NHS.

Abstract
Mutations in CCAAT enhancer binding protein A gene (CEBPA) are one of the common genetic alterations in acute myeloid leukemia (AML). Recently, the emergence of new evidence makes it necessary to reconsider the subsets and treatment of AML patients with CEBPA mutations. This review will summarize the history of research progress of CEBPA mutations in AML, the heterogeneities of AML with CEBPA double mutations (CEBPA dm), and two special subtypes of CEBPA mutated AML. We will discuss the treatment of AML with CEBPA mutations as well, and finally propose a new algorithm for the treatment of these patients, including both familial and sporadic CEBPA mutated AML patients. This review may be beneficial for further investigation and optimizing clinical management of AML patients with CEBPA mutations.

Cost-Effectiveness of Inotuzumab Ozogamicin Compared to Standard of Care Chemotherapy for Treating Relapsed or Refractory Acute Lymphoblastic Leukaemia Patients in Norway and Sweden. PHARMACOECONOMICS - OPEN 2022; 6:47-62. [PMID: 34309818 PMCID: PMC8807767 DOI: 10.1007/s41669-021-00287-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Accepted: 06/27/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVE The aim was to estimate the cost-effectiveness of inotuzumab ozogamicin (InO) versus standard of care chemotherapy (SoC) for adults with relapsed or refractory B cell acute lymphoblastic leukaemia (R/R ALL) in Sweden and Norway, and compare this to evaluations made by the health technology assessment (HTA) authorities Tandvårds- och läkemedelsförmånsverket (TLV) and the Norwegian Medicines Agency (NoMA). MATERIALS AND METHODS A partitioned survival model was developed to determine incremental cost-effectiveness ratios (ICERs) for InO versus SoC. Parametric survival models were fit to overall survival and progression-free survival Kaplan-Meier data from the INO-VATE ALL phase III trial. Two base cases were run using (1) Swedish and (2) Norwegian inputs (costs and discount rates). Core clinical inputs and utilities did not differ between countries. Analyses were then conducted to reflect the preferred assumptions of TLV and NoMA. Univariate and multivariate sensitivity analyses were performed. RESULTS The base case deterministic ICERs for InO versus SoC were €16,219/quality-adjusted life years (QALY) in Sweden (probabilistic €19,415) and €44,405/QALY in Norway (probabilistic €47,305). The ICERs using our model but applying the preferred assumptions of TLV or NoMA were €74,061/QALY (probabilistic €77,484) and €59,391/QALY (probabilistic €63,632), respectively. Differences between our base cases and the ICERs with TLV and NoMA settings were mainly explained by the exclusion of productivity costs and use of pooled post-haematopoietic stem-cell transplant (post-HSCT) survival in Sweden and use of higher HSCT costs in Norway. All ICERs remained below the approximated willingness-to-pay thresholds. The probability of InO being cost-effective ranged from 77 to 99% versus SoC. CONCLUSIONS InO can likely be considered cost-effective versus SoC under our and the HTA-preferred settings.

Abstract
BACKGROUND AND OBJECTIVE The phase III ALFA-0701 study demonstrated the efficacy and safety of gemtuzumab ozogamicin (GO) versus standard of care (SOC) chemotherapy (daunorubicin and cytarabine) for the treatment of adult patients with de novo CD33+ acute myeloid leukaemia (AML). This study analysed the cost-effectiveness of GO from the perspective of the UK health care payer. METHODS A cohort state-transition model was developed to estimate direct health care costs and quality-adjusted life-years (QALYs) over a lifetime time horizon from AML diagnosis to death using monthly cycles. Data on complete remission, overall survival, relapse-free survival (RFS), haematopoietic stem-cell transplantation, and adverse events for GO plus SOC versus SOC were obtained from the ALFA-0701 study. Overall survival and RFS were extrapolated beyond the trial horizon using mixture cure models. Unit costs were obtained from standard national sources. Utilities were identified in a systematic literature review. Costs and outcomes were discounted at 3.5%. Analyses were performed for the base-case population, excluding patients with an unfavourable cytogenetic profile, and the overall population. RESULTS For the base-case and overall populations respectively, incremental per-patient costs (£13,456 and £14,773) and QALYs (0.99 and 0.68) for GO plus SOC versus SOC resulted in incremental cost-effectiveness ratios (ICERs) of £13,561 and £21,819 per QALY gained. The mean probabilistic ICERs were £14,217 and £23,245, respectively. Univariate sensitivity analyses supported the robustness of the results. CONCLUSIONS The ICERs for both populations met NICE's £20,000-£30,000 willingness-to-pay threshold for medicines and supported the current approval for GO.

Abstract
Acute myeloid leukemia with bi-allelic CEBPA mutation was categorized as an independent disease entity with favorable prognosis, however, recent researches have revealed huge heterogeneity within this disease group, and for some patients, relapse remained a major cause of treatment failure. Further risk stratification is essentially needed. Here by reviewing the latest literature, we summarized the characteristics of CEBPA mutation profiles and clinical features, with a special intention of dissecting the heterogeneity within the seemingly homogeneous AML with bi-allelic CEBPA mutations. Specifically, non-classical CEBPA mutation, miscellaneous companion genetic aberrations and the presence of germline CEBPA mutation are three major sources of heterogeneity. Identifying these factors can help us predict patients at a higher risk of relapse, for whom aggressive treatment may be recommended. Novel therapeutic approaches regarding manipulating potentially druggable targets as well as the debate over post remission consolidation regimens has also been discussed.

Abstract
The long-standing debate of whether patients with acute myeloid leukemia (AML) should proceed to allogeneic hematopoietic cell transplantation (HCT) during first complete remission (CR1) remains unsettled. Although allogeneic HCT during CR1 used to be recommended for those with intermediate or poor cytogenetics if they had a matched sibling donor, the concept of indications for allogeneic HCT during CR1 has been evolving by virtue of advances in understanding of the molecular pathogenesis of AML and innovations in transplantation practice attained over the last few decades. The incorporation of molecular profiles of leukemia has been shown to contribute to further refinements of risk classification that had previously relied mostly on cytogenetics, while the progress in transplantation procedures has made it possible to perform transplantations more safely even for patients without a matched sibling donor. These significant changes have underpinned the need to reappraise indications for allogeneic HCT during CR1 of AML. Improvements in clinical applications of genetic and measurable residual disease information as well as in transplantation technology are expected to further refine indications for allogeneic HCT during CR1, and thus promote an individualized approach for the treatment of AML.

Abstract
Objective To assess the incremental cost-utility ratio (ICUR) of gemtuzumab ozogamicin (GO) + standard of care (SOC) vs SOC alone for treatment of patients with de novo AML from a Spanish Health Service perspective. Methods A cohort state-transition model, with 12 health-states, was used to estimate the lifetime accumulated cost and benefits in terms of quality-adjusted-life-years (QALYs) in AML patients with favourable, intermediate, and unknown cytogenetic profiles. Patient profile was defined based on the ALFA-0701 trial. Therapeutic regimens were defined by 5 haematologists. SOC was assumed to be idarubicin and cytarabine, the combination most used in Spain. QALYs were estimated by applying utilities for the time spent by the cohort in each health-state and utility decrements associated with adverse events (AE). Total cost (€,2020) included drug-acquisition, hematologic stem-cell transplantation, disease management, AE management and end-of-life costs. Unit costs were derived from local databases. All parameters were validated by haematologist. Costs and outcomes were discounted (3%/year). Results Higher cost/patient (€177,618 vs €151,434) and greater QALYs (5,70 vs 4,62) were obtained with GO+SOC vs SOC. The ICUR was €24,203/QALY gained. Conclusion This simulation suggests that GO + SOC could be a cost-effective option for treatment of patients with de novo AML in first line.

Abstract
OBJECTIVES We performed a systematic review of health state utility values (HSUVs) obtained using the EQ-5D questionnaire for patients with hematologic malignancies. METHODS The following databases were searched up to September 2018: MEDLINE, EMBASE, The Cochrane Library, and the EQ-5D publications database on the EuroQol website. Additional references were extracted from reviewed articles. Only studies presenting EQ-Index results were incorporated. In view of the heterogeneity across the included publications, we limited ourselves to a narrative synthesis of original HSUVs found. RESULTS Fifty-nine studies (described in 63 articles) met the inclusion criteria. Data from 21 635 respondents provided 796 HSUV estimates for hematologic malignancy patients. EQ-Index scores ranged from -0.025 to 0.980. The most represented area was multiple myeloma (4 studies, 11 112 patients, and 249 HSUVs). In clinical areas such as chronic myeloid leukemia, acute myeloid leukemia, chronic lymphocytic leukemia, non-Hodgkin lymphoma, and mantle cell lymphoma, we described over 50 health utilities in each. In contrast, we identified only 13 HSUVs (based on 4 studies and the data of 166 patients) for Hodgkin lymphoma. Areas without EQ-5D-based health utilities comprised: polycythemia vera, primary myelofibrosis, essential thrombocythemia, mastocytosis, myeloid sarcoma, chronic myelomonocytic, eosinophilic leukemia, and neutrophilic leukemia. CONCLUSIONS There is a wide range of HSUVs available for hematologic cancer patients with different indications. The review provides a catalog of utility values for use in cost-effectiveness models for hematologic malignancies.

The prognostic impact of FLT3-ITD, NPM1 and CEBPa in cytogenetically intermediate-risk AML after first relapse. Int J Hematol 2020; 112:200-209. [PMID: 32495317 DOI: 10.1007/s12185-020-02894-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 03/30/2020] [Accepted: 05/22/2020] [Indexed: 12/19/2022]
Abstract
We evaluated the impact of FLT3-ITD, NPM1 mutations, and double mutant CEBPa (dmCEBPa) on overall survival (OS) after relapse in patients with cytogenetically intermediate-risk acute myeloid leukemia (AML) who were treated with chemotherapy alone in the first remission (CR1). Patients aged 16-65 years diagnosed with cytogenetically intermediate-risk AML, and who achieved CR1 were included. We retrospectively analyzed FLT3-ITD, NPM1 mutations and CEBPa using samples obtained at diagnosis, which therefore did not affect the therapeutic decisions. Among 235 patients who had achieved CR1, 152 relapsed, and 52% of them achieved second CR. The rate of achieving second CR was significantly higher (85%) in those with dmCEBPa. Patients with FLT3-ITD had significantly worse OS after relapse than those without (19% vs 41%, p = 0.002), while OS was comparable between patients with and without NPM1 mutations (37% vs 34%, p = 0.309). Patients with dmCEBPa had improved OS than those without (61% vs 32%, p = 0.006). By multivariate analysis, FLT3-ITD was independently associated with worse OS after relapse [hazard ratio (HR) 1.99, 95% CI 1.27-3.12, p = 0.003], and dmCEBPa with improved OS (HR 0.40, 95% CI 0.17-0.93, p = 0.033). Our data show that screening for these mutations at diagnosis is useful for facilitating effective therapeutic decision-making even after relapse.

A decision analysis comparing unrelated bone marrow transplantation and cord blood transplantation in patients with aggressive adult T-cell leukemia-lymphoma. Int J Hematol 2019; 111:427-433.

Abstract
Patients with aggressive adult T-cell leukemia-lymphoma (ATL) have dismal outcomes with intensive chemotherapy. Early up-front allogeneic hematopoietic stem cell transplantation (allo-HSCT) is generally recommended. However, the choice of stem cell source, i.e., unrelated bone marrow transplant (UBMT) or cord blood transplantation (CBT), when an HLA-matched related donor is unavailable remains controversial. Thus, we undertook a decision analysis to compare the outcomes of two therapeutic strategies: chemotherapy followed by up-front UBMT at 6 months, and chemotherapy followed by up-front CBT at 3 months. Patients were stratified into low-, intermediate-, and high-risk groups according to the modified ATL-prognostic index. The model simulated life expectancy (LE) and quality-adjusted LE (QALE). LE following up-front UBMT was higher than that following up-front CBT in the low-risk group (2.63 vs. 2.28 years), but was comparable in the intermediate- (2.06 vs. 2.01 years) and high-risk groups (1.25 vs. 1.30 years). The Monte Carlo simulation for LE and QALE in each risk group showed that there was significant uncertainty in all categories. In conclusion, up-front UBMT was superior to up-front CBT in the low-risk group, but the strategies were comparable in the intermediate- and high-risk groups.

Abstract
The National Institute for Health and Care Excellence (NICE) invited Pfizer, the manufacturer of inotuzumab ozogamicin (henceforth inotuzumab), to submit clinical- and cost-effectiveness evidence for inotuzumab as part of NICE's single technology appraisal process. The Centre for Reviews and Dissemination and the Centre for Health Economics, both at the University of York, were commissioned as the independent evidence review group (ERG). The clinical-effectiveness data were from a multicentre randomised controlled trial that compared inotuzumab with standard of care (SoC), where SoC was the investigator's choice of chemotherapy. Inotuzumab demonstrated statistically significant improvements in response rates or in the proportion of patients progressing to haematopoietic stem cell transplant (HSCT) but failed to meet the second primary objective of longer overall survival. Treatment-emergent adverse events were more frequent in the SoC arm, except veno-occlusive disease, which was more frequent in the inotuzumab arm. The company's economic model split patients into three post-hoc subgroups and used a partitioned survival approach within each group, with a cure assumption 3 years after receiving HSCT. In contrast with the trial results, the economic model estimated substantial improvement in survival with inotuzumab compared with SoC, providing an additional 5.2 life-years and 2.2 quality-adjusted life-years (QALYs) using a discount rate of 1.5% per annum. The ERG's critique highlighted a number of concerns, including the use of a post-hoc post-randomisation patient subset for extrapolation, the choice of a 1.5% discount rate, the complexity of the parametric modelling, the assumption of further treatment benefit post-HSCT, the nature of the cure assumption, and the length of inpatient stay while receiving treatment. The combination of the ERG's adjustments resulted in an incremental cost-effectiveness ratio (ICER) of £122,174 per QALY gained using Kaplan-Meier survival estimates and £114,078 per QALY gained with parametric survival models fit to the trial data. The final determination of the appraisal followed four NICE Appraisal Committee meetings, an appeal by the company and other stakeholders, two patient access schemes, and a company response to each appraisal consultation. The final ICER post-consultation was between £33,749 and £37,497 per QALY gained compared with SoC (excluding the confidential discount for blinatumomab received as subsequent therapy). The Appraisal Committee concluded that the ICER for inotuzumab was within the range usually considered cost effective for end-of-life care and recommended inotuzumab within its licensed indication.
