Budget impact analysis of durvalumab consolidation therapy vs no consolidation therapy after chemoradiotherapy in stage III non-small cell lung cancer in the context of the Chilean health care system.

BACKGROUND: Durvalumab, used as consolidation immunotherapy, has shown to improve survival in patients with stage III non-small cell lung cancer who respond to chemoradiotherapy, based on the most recent follow-up of PACIFIC. The Chilean healthcare system provides access to certain immunotherapies for this condition. The present study sought to estimate the budget impact of durvalumab versus standard of care in the context of the Chilean healthcare system. RESEARCH DESIGN AND METHODS: A partitioned survival model was adapted to compare two strategies: durvalumab as consolidation therapy and standard of care for treating stage III NSCLC. The number of patients eligible for treatment was estimated using published incidence data and modeled for a 5-year time horizon. Model inputs were based on published literature, and the duration of treatment was estimated using survival curves obtained from PACIFIC. Costs were estimated in Chilean pesos (CLP) and converted to USD dollars using an exchange rate of USD 1 = CLP 827. Scenario analyses were performed to assess different subsequent therapy splits, variations in the target population and dosage of durvalumab. RESULTS: Durvalumab uptake projected total costs ranging from USD 1.27 in Year 1 to 8.5 million in Year 5 from the public perspective. From the private perspective, the budget impact for the first year is USD 1.3 million to USD 3 million for 2028. This difference relies mostly on the lower number of patients treated. Both perspectives anticipated cost savings over the time horizon through reduced monitoring, adverse events, and end-of-life expenses. CONCLUSIONS: This study demonstrates that the inclusion of Durvalumab for NSCLC in Chile represents an investment in the Chilean health system. The incremental costs align with clinical benefits and potential savings in healthcare resource utilization. However, a comprehensive cost-effectiveness analysis is needed to evaluate its economic value thoroughly.

Cost-effectiveness and Budgetary Consequence Analysis of Durvalumab Consolidation Therapy vs No Consolidation Therapy After Chemoradiotherapy in Stage III Non-Small Cell Lung Cancer in the Context of the US Health Care System.

Importance: In early 2018, durvalumab became the first immunotherapy to be approved for adjuvant treatment of patients with unresectable stage III non-small cell lung cancer (NSCLC) whose cancer has not progressed after definitive chemoradiotherapy. However, the cost-effectiveness and potential economic implications of using this high-priced therapy in this indication are unknown to date. Objective: To explore the cost-effectiveness and potential budgetary consequences of durvalumab consolidation therapy vs no consolidation therapy after chemoradiotherapy in stage III NSCLC in the context of the US health care system. Design, Setting, and Participants: A decision analytic microsimulation model was developed in an academic medical setting to compare the following 2 postchemoradiotherapy strategies: all patients receive no consolidation therapy until progression vs all patients receive durvalumab consolidation therapy until progression or for a maximum of 1 year. The potential budgetary consequence was calculated by applying the proportion of patients with NSCLC who were diagnosed in stage III and received chemoradiotherapy to the projected number of annual new cases for 2018 to 2022 to find total eligible patients and then multiplied by the mean difference in annual cost between the strategies over this 5-year period. Simulated conditions were matched to those of the PACIFIC phase 3 randomized clinical trial and reasonable treatment strategies for metastatic NSCLC. All simulated patients begin disease free after having received radical treatment with chemoradiotherapy and are followed up as they progress to metastatic disease first-line treatment, metastatic disease second-line treatment, end-stage progressive disease, and death. Main Outcomes and Measures: The main outcome of this study was the incremental cost-effectiveness ratio of durvalumab consolidation therapy vs no consolidation therapy, given as aggregate cost of treatment per quality-adjusted life-year gained. Results: Among 2 million simulated patients, durvalumab consolidation therapy was cost-effective compared with no consolidation therapy at a $100 000 per quality-adjusted life-year willingness-to-pay threshold, with an estimated incremental cost-effectiveness ratio of $67 421 per quality-adjusted life-year, and would contribute an additional $768 million to national cancer spending in year 1. The annual budgetary consequence would then decrease to $241 million in year 5. Conclusions and Relevance: Durvalumab consolidation therapy represents an indication where expensive immunotherapies can be cost-effective. Treating with immunotherapy earlier in the course of cancer progression can provide significant value, despite having a substantial budgetary consequence.

Cost-effectiveness analysis of consolidation with brentuximab vedotin for high-risk Hodgkin lymphoma after autologous stem cell transplantation.

BACKGROUND: In a recent randomized, placebo-controlled trial, consolidation treatment with brentuximab vedotin (BV) decreased the risk of Hodgkin lymphoma (HL) progression after autologous stem cell transplantation (ASCT). However, the impact of BV consolidation on overall survival, quality of life, and health care costs remain unclear. METHODS: A Markov decision-analytic model was constructed to measure the costs and clinical outcomes for BV consolidation therapy compared with active surveillance in a cohort of patients aged 33 years who were at risk for HL relapse after ASCT. Life-time costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated for each post-ASCT strategy. RESULTS: After quality-of-life adjustments and standard discounting, upfront BV consolidation was associated with an improvement of 1.07 QALYs compared with active surveillance plus BV as salvage. However, the strategy of BV consolidation led to significantly higher health care costs ($378,832 vs $219,761), resulting in an ICER for BV consolidation compared with active surveillance of $148,664/QALY. If indication-specific pricing was implemented, then the model-estimated BV price reductions of 18% to 38% for the consolidative setting would translate into ICERs of $100,000 and $50,000 per QALY, respectively. These findings were consistent on 1-way and probabilistic sensitivity analyses. CONCLUSIONS: BV as consolidation therapy under current US pricing is unlikely to be cost effective at a willingness-to-pay threshold of $100,000 per QALY. However, indication-specific price reductions for the consolidative setting could reduce ICERs to widely acceptable values. Cancer 2017. © 2017 American Cancer Society.

Sharing post-AML consolidation supportive therapy with local centers reduces patient travel burden without compromising outcomes.

Acute myeloid leukemia (AML) is frequently treated with induction and consolidation chemotherapy. Consolidation chemotherapy can be delivered on an ambulatory basis, requiring some patients to travel long distances for treatment at specialized centers. We developed a shared care model where patients receive consolidation chemotherapy at a quaternary center, but post-consolidation supportive care at local hospitals. To evaluate the impact of our model on patient travel and outcomes we conducted a retrospective analysis of AML and acute promyelocytic leukemia patients receiving consolidation over four years at our quaternary center. 73 patients received post-consolidation care locally, and 344 at the quaternary center. Gender, age and cytogenetic risk did not significantly differ between groups. Shared care patients saved mean round trip distance of 146.5km±99.6 and time of 96.7min±63.4 compared to travelling to quaternary center. There was no significant difference in overall survival between groups, and no increased hazard of death for shared care patients. 30, 60, and 90day survival from start of consolidation was 98.6%, 97.2%, and 95.9% for shared care and 98.8%, 97.1%, and 95.3% for quaternary center patients. Thus, a model utilizing regional partnerships for AML post-consolidation care reduces travel burden while maintaining safety.

Medical costs of treatment and survival of patients with acute myeloid leukemia in Belgium.

The advent of new cell-based immunotherapies for leukemia offers treatment possibilities for certain leukemia subgroups. The wider acceptability of these new technologies in clinical practice will depend on its impact on survival and costs. Due to the small patient groups who have received it, these aspects have remained understudied. This non-randomized single-center study evaluated medical costs and survival for acute myeloid leukemia between 2005 and 2010 in 50 patients: patients treated with induction and consolidation chemotherapy (ICT) alone; patients treated with ICT plus allogeneic hematopoietic stem cell transplantation (HCT), which is the current preferred post-remission therapy in patients with intermediate- and poor-risk AML with few co-morbidities, and patients treated with ICT plus immunotherapy using autologous dendritic cells (DC) engineered to express the Wilms' tumor protein (WT1). Total costs including post- consolidation costs on medical care at the hematology ward and outpatient clinic, pharmaceutical prescriptions, intensive care ward, laboratory tests and medical imaging were analyzed. Survival was markedly better in HCT and DC. HCT and DC were more costly than ICT. The median total costs for HCT and DC were similar. These results need to be confirmed to enable more thorough cost-effectiveness analyses, based on observations from multicenter, randomized clinical trials and preferably using quality-adjusted life-years as an outcome measure.

Costo-efectividad de los tratamientos de consolidación para la leucemia mieloide aguda en niños en riesgo alto en el sistema de salud colombiano / Cost-effectiveness of consolidation treatments for acute myeloid leukemia in high-risk pediatric patients within the Colombian healthcare system

Introducción. La leucemia mieloide aguda representa alrededor del 20 % de las leucemias en menores de 18 años. Actualmente, solo existen dos alternativas de tratamiento de consolidación: la quimioterapia y el trasplante con progenitores hematopoyéticos. Objeti vo. Evaluar el costo-efectividad del trasplante alogénico con progenitores hematopoyéticos de donantes emparentados o no emparentados, en comparación con la quimioterapia de consolidación en niños de alto riesgo con leucemia mieloide aguda. Materiales y métodos. Se construyó un árbol de decisiones utilizando los años de vida ganados como resultado. Los costos y probabilidades se extrajeron de estudios y reportes que se encuentran en la literatura científica. El umbral de costo-efectividad fue tres veces el producto interno bruto per cápita de 2010. Se hicieron análisis de sensibilidad univariados y probabilísticos, así como una curva de aceptabilidad. Resultados. Al comparar el trasplante de donante emparentado o no emparentado con los ciclos de quimioterapia, se obtuvieron tasas de costo-efectividad incremental de COP$ 9´226.421 (USD$ 4.820) y COP$ 6´544.116 (USD$ 3.419), respectivamente, cifras estas inferiores al producto interno bruto per cápita: COP$ 12´047.418 (USD$ 6.294). El trasplante resultó ser costo-efectivo en 70 % de las simulaciones y con mayor probabilidad de serlo cuando había disposición a pagar cantidades superiores a COP$ 7´200.000 (USD$ 3.762). Conclusión. El trasplante alogénico (emparentado o no) en Colombia resultó ser costo-efectivo frente al tratamiento de consolidación en niños de alto riesgo con leucemia mieloide aguda.

Introduction: Acute myeloid leukemia represents about 20% of leukemias in minors under 18 years old. At present, there are only two consolidation treatment alternatives: Chemotherapy and stem-cell transplantation. Objective: To evaluate the cost-effectiveness of unrelated and related hematopoietic stem cell transplantations, versus chemotherapy consolidation in pediatric patients with high-risk acute myeloid leukemia. Materials and methods: A decision tree was constructed with life-years gained as the outcome. Costs and probabilities were extracted from the literature. Probabilistic sensitivity analyses and acceptability curves were computed. The cost-effectiveness threshold was three times the 2010 per capita gross domestic product. Results: When compared to consolidation chemotherapy cycles, related and unrelated hematopoietic stem-cell transplantation had incremental cost-effectiveness ratios of COP$ 9,226,421 (USD$ 4,820) and COP$ 6,544,116 (USD$ 3,419) respectively, which are lower than the per capita gross domestic product (COP$ 12,047,418, USD$ 6,294). Transplant proved to be cost-effective in 70% of the simulations and had a higher probability of the willingness to pay being over than COP$ 7,200,000 (USD$ 3,762). Conclusion: In Colombia, related and unrelated hematopoietic stem-cell transplants are cost-effective alternatives to consolidation treatment for high-risk acute myeloid leukemia in pediatric patients.

The costs of initial treatment for patients with acute myeloid leukemia in the Netherlands.

The aim of this study was to calculate the costs of the current initial treatment of acute myeloid leukemia. Resource use was collected for 202 patients who started with intensive chemotherapy in 2008 or 2009. The costs of the first induction course were significantly higher than the costs of the second induction course. Allogeneic transplantation from a matched unrelated donor was significantly more expensive than the other consolidation treatments. In-hospital stay was the major cost driver in the treatment of AML. Research regarding possibilities of achieving the same or better health outcome with lower costs is warranted.
