RESUMO
INTRODUCTION: Real-world studies of lower-risk myelodysplastic syndromes (LR-MDS) are limited. We evaluated treatment patterns, clinical outcomes, and healthcare resource utilization (HCRU) among patients with LR-MDS treated with erythropoiesis-stimulating agents (ESAs) in the United States. PATIENTS AND METHODS: This retrospective study included patients with LR-MDS who initiated treatment with ESAs between January 1, 2016 and June 30, 2019. The primary analysis assessed patient demographic and clinical characteristics, treatment patterns, clinical outcomes (hematologic response, transfusion requirements, disease progression), and HCRU (medical encounters, laboratory tests, and medication use). Subgroup analyses of patients repeatedly treated with ESA therapy evaluated selected clinical outcomes and primary ESA failure by SF3B1 mutational status, per recently updated NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines©). RESULTS: A total of 142 patients were included with a median follow-up time of 17 months (interquartile range [IQR], 7-33). Median age at ESA initiation was 79 years (IQR, 73-85). Patients were predominantly male (54%), overweight or obese (32% and 23%, respectively), of White race (96%) and non-Hispanic ethnicity (89%). Overall, 57% patients were initially treated with darbepoetin alfa and 43% with epoetin alfa. Clinical outcomes were poor, and there was a significant burden on both the health system and individual patients treated with ESA therapies. Hematologic improvement- erythroid was only seen in 26% of 142 patients treated with ESAs, and 65% of 82 retreated patients experienced primary ESA failure. CONCLUSION: Our results indicate that primary ESA failure is largely unrecognized and that many patients should be considered for alternative treatments.

BACKGROUND: There is a lack of established clinical outcomes for patients with myelofibrosis (MF) receiving fedratinib following ruxolitinib failure. This study examined real-world patient characteristics, treatment patterns, and clinical outcomes of patients with MF treated with fedratinib following ruxolitinib failure in US clinical practice. PATIENTS AND METHODS: This retrospective patient chart review included adults with a physician-reported diagnosis of MF, who initiated fedratinib after discontinuing ruxolitinib. Descriptive analyses characterized patient characteristics, clinical outcomes, and treatment patterns from MF diagnosis through ruxolitinib and fedratinib treatment. RESULTS: Twenty-four physicians abstracted data for 150 eligible patients. Approximately 55.3% of the patients were male, 68.0% were White, and median age at MF diagnosis was 68 (range, 35-84) years. Median duration of ruxolitinib therapy was 7.6 (range, 0.7-65.5) months. At initiation of fedratinib, 88.0% of patients had palpable spleen and a mean spleen size of 16.0 (standard deviation [SD], 5.9) cm. Spleen size decreased by 19.4% to 13.2 (SD, 7.9) cm at month 3 (P = .0001) and by 53.4% to 7.2 (SD, 7.4) cm at month 6 (P = .01) of fedratinib treatment, respectively. Almost one-third (26.8%) of patients had achieved ≥ 50% spleen reduction by month 6. Mean number of symptoms also decreased significantly at month 3 (P < .0001) and month 6 (P = .01). CONCLUSION: Fedratinib appears to deliver spleen and symptom benefits in real-world patients with MF previously treated with ruxolitinib.

Purpose: The pharmacology, pharmacokinetics, pharmacodynamics, clinical efficacy, and safety of zanbrutinib are described. Summary: Mantle cell lymphoma (MCL) is a mature B-cell lymphoma that is typically associated with unfavorable outcomes, and virtually all patients with MCL have refractory or relapsed disease despite aggressive treatment. The treatment paradigm for MCL has transformed dramatically over the past decade owing to rapid advancements in immunotherapy and molecular-targeted therapies. Zanubrutinib, a second-generation Bruton's tyrosine kinase inhibitor (BTKI) designated for mature B-cell non-Hodgkin's lymphoma (NHL), has drastically improved the survival outcomes in relapsed/refractory (R/R) MCL patients. This selective BTKI is a small molecule that functions by forming a covalent bond in the active site of BTK. The inhibition of BTK activity is essential for the signaling of B-cell antigen receptor (BCR) and cytokine receptor pathways. In a preclinical study, zanubrutinib inhibited malignant B-cell proliferation and reduced tumor growth. Zanubrutinib was granted FDA-accelerated approval based on the results of Phase I and II trials. The investigator-assessed overall response rate was 83.7%, of which 78% of patients achieved complete response. The median duration of response was 19.5 months, and the median progression-free survival was 22.1 months. The most common (≥20%) all-grade adverse events were low neutrophil count (46.5%), upper respiratory tract infection (38.4%), rash (36.0%), low white blood cell count (33.7%), and low platelet count (32.6%). Conclusion: Zanubrutinib is a selective, next-generation, orally active, irreversible BTK inhibitor. The selectivity of zanubrutinib and its superior efficacy, with a well-tolerated safety profile, have proven to be attractive options for other malignancies.
RESUMO
Acute myeloid leukemia (AML) is associated with a substantial clinical and economic burden. This study characterized the magnitude of this burden following initial treatment with standard or less intensive therapies (hypomethylating agents [HMAs]) and throughout different treatment phases post-remission. The Surveillance, Epidemiology, and End Results (SEER) cancer registry (2007-2016) linked with Medicare beneficiary claims (2007-2015) was analyzed. Patients were ≥â¯65 years old with AML who initiated chemotherapy or HMAs and achieved remission. Outcomes included baseline characteristics, treatment patterns, clinical outcomes, healthcare resource utilization (HRU), and costs (2019 United States dollar). Economic impacts were stratified by treatment phase (initial treatment, early post-remission, late post-remission, and post-relapse). Early and late post-remission were defined as treatment initiated ≤â¯60 days and >â¯60 days following initial treatment, respectively. A subgroup analysis of patients receiving only HMAs as initial treatment was also conducted. Overall, 530 patients were included (mean age: 74.1 years; 53.6 % male). In the overall analysis, 68.1 % of patients received post-remission treatment; 31.9% had no post-remission treatment. Mean monthly per patient healthcare costs by treatment phase were $45,747 (initial treatment), $30,248 (early post-remission), $23,173 (late post-remission), and $37,736 (post-relapse), driven predominantly by inpatient visits. The HMA subgroup analysis comprised 71 patients (mean age: 78.8 years; 50.7 % male); mean monthly per patient healthcare costs were highest post-relapse. The economic burden of AML among older patients is substantial across all treatment phases. AML treatments that induce and prolong remission may reduce HRU and the economic burden of disease.

BACKGROUND: Cancer treatment is a significant driver of rising health care costs in the United States, where the annual cost of cancer care is estimated to reach $246 billion in 2030. As a result, cancer centers are considering moving away from fee-for-service models and transitioning to value-based care models, including value-based frameworks (VBFs), clinical care pathways (CCPs), and alternative payment models (APMs). OBJECTIVE: To assess the barriers and motivations for using value-based care models from the perspectives of physicians and quality officers (QOs) at US cancer centers. METHODS: Sites were recruited from cancer centers in the Midwest, Northeast, South, and West regions in a 15/15/20/10 relative distribution. Cancer centers were identified based on prior research relationships and known participation in the Oncology Care Model or other APMs. Based on a literature search, multiple choice and open-ended questions were developed for the survey. A link to the survey was emailed to hematologists/oncologists and QOs at academic and community cancer centers from August to November 2020. Results were summarized using descriptive statistics. RESULTS: A total of 136 sites were contacted; 28 (21%) centers returned completed surveys, which were included in the final analysis. 45 surveys (23 from community centers, 22 from academic centers) were completed: 59% (26/44), 76% (34/45), and 67% (30/45) of physicians/QOs respondents had used or implemented a VBF, CCP, and APM, respectively. The top motivator for VBF use was "producing real-world data for providers, payers, and patients" (50% [13/26]). Among those not using CCPs, the most common barrier was a "lack of consensus on pathway choices" (64% [7/11]). For APMs, the most common difficulty was that "innovations in health care services and therapies must be adopted at the site's own financial risk" (27% [8/30]). CONCLUSIONS: The ability to measure improvements in cancer health outcomes was a large motivator for implementing value-based models. However, heterogeneity in practice size, limited resources, and potential increase in costs were possible barriers to implementation. Payers need to be willing to negotiate with cancer centers and providers to implement the payment model that will most benefit patients. The future integration of VBFs, CCPs, and APMs will depend on reducing the complexity and burden of implementation.

Aim: To define ruxolitinib failure and develop parameters to guide transition to next-line therapy for patients with myelofibrosis. Methods: A modified Delphi panel with 14 hematologists-oncologists. Survey concepts included defining primary refractory status, loss of response, disease progression, intolerance and transition to next-line therapy. Results: Ruxolitinib failure may be defined as no improvement in symptoms or spleen size, progressive disease or ruxolitinib intolerance, following a maximally tolerated dose for ≥3 months. Loss of spleen response 1 month after initial response may prompt discontinuation. Lack of evidence to inform transition to next-line therapy was noted; tapering ruxolitinib should be considered according to ruxolitinib dose and patient characteristics. Conclusion: Expert consensus was provided on defining ruxolitinib failure and transition to next-line therapy as summarized in this position paper, which may support considerations in the development of future clinical practice guidelines.
People with myelofibrosis who receive treatment with ruxolitinib may need to stop treatment because it is not working or they cannot tolerate the side effects. There is little good scientific information available about how and when to stop ruxolitinib treatment, and how to move to another treatment after stopping ruxolitinib. A group of clinical experts in hematology and oncology followed a scientific process, called the Delphi method, to discuss this topic and to reach agreement on the most important aspects of this challenge. The experts agreed that ruxolitinib failure may be defined as having no improvement in symptoms or spleen size, progressive disease or ruxolitinib intolerance, after the patient was receiving the highest dose they could tolerate for ≥3 months. The results of this expert discussion may support patients and their healthcare providers making decisions in real life, and development of future clinical practice guidelines.

INTRODUCTION: Treatment with dasatinib for chronic myeloid leukemia (CML) has been associated with development of pleural effusion; however, data regarding its optimal management are limited. We examined treatment patterns and healthcare resource utilization (HCRU) and costs among patients with CML treated with dasatinib who experienced a subsequent pleural effusion. METHODS: Adults with CML and ≥1 pharmacy claim for dasatinib in 2015-2018 who experienced pleural effusion after dasatinib were identified using data from claims databases. RESULTS: Overall, 123 patients were eligible. After 1 year, of the 38.2% of patients with a dose modification, 72.3% did not switch treatment; among these patients, 70.6% continued treatment. Among patients with a stable dose after pleural effusion (61.8%), 57.9% later switched to another TKI. The mean (SD) duration of dasatinib treatment after pleural effusion was 262.0 (124.0) days for patients with a dose modification versus 149.1 (155.2) days for those with a stable dose (p < 0.001). HCRU and costs were similar between groups. CONCLUSION: Dasatinib dose modification after pleural effusion was not always required; however, patients with dose modifications continued therapy for a longer duration with a lower rate of switching to another TKI versus patients who remained on a stable dose.

BACKGROUND: Real-world evidence is a valuable source of information in healthcare. This study describes the challenges and successes during algorithm development to identify cancer cohorts and multi-agent chemotherapy regimens from claims data to perform a comparative effectiveness analysis of granulocyte colony stimulating factor (G-CSF) use. METHODS: Using the Biologics and Biosimilars Collective Intelligence Consortium's Distributed Research Network, we iteratively developed and tested a de novo algorithm to accurately identify patients by cancer diagnosis, then extract chemotherapy and G-CSF administrations for a retrospective study of prophylactic G-CSF. RESULTS: After identifying patients with cancer and subsequent chemotherapy exposures, we observed only 12% of patients with cancer received chemotherapy, which is fewer than expected based on prior analyses. Therefore, we reversed the initial inclusion criteria to identify chemotherapy receipt, then prior cancer diagnosis, which increased the number of patients from 2,814 to 3,645, or 68% of patients receiving chemotherapy had diagnoses of interest. Additionally, we excluded patients with cancer diagnoses that differed from those of interest in the 183 days before the index date of G-CSF receipt, including early-stage cancers without G-CSF or chemotherapy exposure. By removing this criterion, we retained 77 patients who were previously excluded. Finally, we incorporated a 5-day window to identify all chemotherapy drugs administered (excluding oral prednisone and methotrexate, as these medications may be used for other non-malignant conditions) as patients may fill oral prescriptions days to weeks prior to infusion. This increased the number of patients with chemotherapy exposures of interest to 6,010. The final cohort of included patients, based on G-CSF exposure, increased from 420 from the initial algorithm to 886 using the final algorithm. CONCLUSIONS: Medications used for multiple indications, sensitivity and specificity of administrative codes, and relative timing of medication exposure must all be evaluated to identify patient cohorts receiving chemotherapy from claims data.

BACKGROUND: We aimed to estimate the incremental lifetime effects, costs, and net-monetary-benefit (NMB) of knowing BRCA information by testing of patients with low-risk localized prostate cancer (PCa) in the US and guiding subsequent screening and treatment, and the cumulative savings or losses of yearly cohort testing over 16 years. We compared two strategies: (1)'with BRCA information' and (2)'without BRCA information.' We also estimated the expected value of perfect information. METHODS: The incremental NMB (INMB) quantified the monetized benefit per person of knowing BRCA status. The net-monetized-value of knowing BRCA information was estimated by multiplying the INMB with the eligible population. RESULTS: The INMBs of knowing BRCA information were $43,357 (payer) and $43,487 (society). in payer and societal perspectives, respectively. Escalated to the eligible patients in 2020, knowing BRCA status resulted in net monetized lifetime value of $1.7 billion (payer and society) for the 2020 cohort; and yielded accumulated net-monetized-value of $28.0 billion (payer) and $28.1 billion (society) over 16 yearly cohorts of eligible PCa patients. CONCLUSIONS: The economic value of knowing BRCA status for all low-risk localized PCa patients in the US provides short-term and long-term evidence for BRCA testing to screen early and optimize treatment.

BACKGROUND: This study aimed to estimate the incremental lifetime effects, costs, and net monetary benefit (NMB) of knowing BRCA information by universal genetic testing of all US women without breast cancer turning 40 in a given year, and the cumulative savings or losses of yearly cohort testing over 16 years. We compared two strategies: (1) 'with BRCA information' and (2) 'without BRCA information.' METHODS: Incremental NMB (INMB) was calculated as the monetized benefit per person of knowing BRCA status. The net monetized value (cumulated INMB) of knowing BRCA information was estimated by multiplying the INMB with the eligible population or the year 2020 cohort of US women age 40 and extended for a total of 16 yearly cohorts. RESULTS: Universal testing of the female population at the age of 40 in a given year provided aan INMB of $663/person (payer) and $1,006/person (society).Escalated to the U.S. population of women age 40 , knowing BRCA status resulted in lifetime cumulated INMB of $1.3 billion (payer) and $2.0 billion (society) for the 2020 cohort; and yielded accumulated monetized value of $18.3 billion (payer) and $27.6 billion (society) over 16 yearly cohorts of 40-year-old women. CONCLUSIONS: The universal testing for BRCA status of all US women at age 40 provides compelling short-term and long-term economic value.

BACKGROUND: This study aimed to estimate the incremental lifetime effects, costs, and net monetary benefit (NMB) of knowing BRCA information for recurrent ovarian cancer (ROC) patients in a given year and the cumulative savings of yearly hypothetical cohort testing over 16 years. We compared two strategies: (1) 'with BRCA information' and (2) 'without BRCA information.' METHODS: Incremental NMB (INMB) was calculated as the average net monetized benefit of knowing BRCA status. The net monetized value (cumulative INMB) of knowing BRCA information was estimated by multiplying the INMB with the eligible ROC patients in year 2020 and extended for potential ROC patients over 16 yearly hypothetical cohorts of ROC patients. RESULTS: Knowing BRCA information for ROC patients provided an additional monetized value of $3,528 in (payer) and $3,194 (society). Escalated to all ROC patients in the U.S. and future incidence ROC estimates, knowing BRCA information resulted in a lifetime cumulative INMB of $35.6 million (payer) and $32.2 million (society) for the 2020 cohort; and yielded an accumulated value of $97.3 million (payer) and $88.0 million (society) over 16 yearly hypothetical cohorts of ROC patients. CONCLUSIONS: The economic value of knowing BRCA status of all U.S. ROC patients provides short-term and long-term evidence for optimizing treatment.

BACKGROUND: Biosimilars are of increasing significance to pharmacy practice, with the potential to improve patient access to biologic therapies and help reduce overall health care costs. OBJECTIVES: This web-based survey assessed pharmacists' understanding of biosimilars, including interchangeability. METHODS: WebMD LLC fielded a survey including true or false and Likert-type questions to the Medscape pharmacist and certified pharmacy technician (CPT) panel in March 2021. Those practicing in community, home care or infusion, hospital or health system, managed care, outpatient, or specialty pharmacy settings and currently providing prescription services, or formulary or benefit management related to biologic products were included, to a quota of 500 responses. Results were analyzed descriptively. RESULTS: Data are reported for 507 of 992 respondents (265 did not meet eligibility criteria, 220 responded after the survey closed), including 498 pharmacists and 9 CPTs. These respondents worked in a community setting (66%), outpatient or ambulatory or other setting (16%), hospital or health system setting (14%), or managed care (5%). Overall, 87% and 91% of respondents knew that the biosimilar had equivalent efficacy and safety, respectively, to its reference product. Only 20% understood that a pharmacist can substitute a Food and Drug Administration-approved interchangeable without approval of the prescriber. However, 53% responded that they felt it was appropriate for a pharmacist to dispense an interchangeable in place of its reference product without authorization from the prescriber if consistent with state law; a numerically smaller proportion of community pharmacists understood this concept than the other groups (50% vs. 54%-61%). Only 11% of respondents knew that no biosimilars were designated as interchangeable at the time of the survey, with a numerically greater proportion of managed care pharmacists showing awareness than other groups. Slightly more than 50% of respondents felt that they were moderately or very comfortable in responding to patients' biosimilar questions. CONCLUSION: Gaps remain in pharmacists' understanding and comfort with key concepts about biosimilar products, including interchangeability, suggesting the need for further education.

Aim: Evaluate the relative efficacy of oral versus injectable azacitidine (AZA) maintenance therapy in acute myeloid leukemia (AML) after complete remission. Materials & methods: Systematic literature review identified QUAZAR AML-001, HOVON 97 AML, UK NCRI AML16 and QoLESS-AZA-AMLE (sensitivity analysis) trials. Network meta-analysis and matching-adjusted indirect comparisons assessed survival outcomes. Results: In the network meta-analysis, combining the HOVON 97 and UK NCRI trials, oral AZA (QUAZAR) was associated with significantly improved overall survival (OS) versus injectable AZA (hazard ratio: 0.744; 95% credible interval: 0.557-0.998). After matching-adjusted indirect comparisons, to address differences in patient characteristics across trials, OS improvements were maintained with oral versus injectable AZA (hazard ratio: 0.753; credible interval: 0.563-0.998). Conclusion: In AML, maintenance therapy with oral AZA was associated with improved OS versus injectable AZA.
Older people with acute myeloid leukemia (AML) may have remission with or without blood count recovery, after first-line chemotherapy; however, remission is short lived and overall survival is limited (712 months). Ongoing treatment (maintenance therapy) after response to initial chemotherapy may prolong remission. Maintenance therapy with azacitidine (AZA) given by injection beneath the skin (subcutaneous) or into a vein (intravenous) can extend disease-free survival compared with no further treatment and best supportive care. However, treatment with intravenous AZA may only extend overall survival in certain patients. ONUREG® is a novel formulation of AZA that can be taken by mouth (orally), remains in the body for longer periods and has the potential for significant clinical benefits compared with intravenous AZA. Presently, there are no studies directly comparing outcomes of maintenance therapy with oral and injectable AZA in older people with AML. In this analysis, we used an indirect treatment comparison method including four clinical trials to explore the survival benefit associated with ONUREG and injectable AZA when used as maintenance therapies after response to initial chemotherapy in older people with AML. Findings showed ONUREG significantly improved overall survival compared with injectable AZA, with an almost 26% reduction in the risk of death. These results suggest that maintenance therapy with ONUREG significantly improves overall survival compared with injectable AZA in older people with AML who may have remission with or without blood count recovery, after first-line chemotherapy.
RESUMO
Aim: This retrospective, observational study assessed healthcare resource utilization (HCRU) and costs for newly diagnosed acute myeloid leukemia (AML) patients receiving intensive induction chemotherapy. Materials & methods: Adult AML patients with inpatient hospitalization or hospital-based outpatient visit receiving intensive induction chemotherapy (CPX-351 or 7 + 3 treatments) were identified from the Premier Healthcare Database (US). Results: All 642 patients had inpatient hospitalizations (median number = 2; median length of stay = 16 days); 22.4% had an ICU admission. Median total outpatient hospital cost was US$2904 per patient, inpatient hospital cost was $83,440 per patient, and ICU cost was $16,550 per patient. Discussion: In the US hospital setting, substantial HCRU and costs associated with intensive induction chemotherapy for AML were driven by inpatient hospitalizations.

Enasidenib was approved by the Food and Drug Administration in 2017 for the treatment of patients with relapsed or refractory (RR) acute myeloid leukemia (AML) with an isocitrate dehydrogenase-2 (IDH2) mutation. Given limited data in clinical practice, this study assessed real-world clinical outcomes and healthcare resource use in patients with RR AML. Physicians performed chart abstraction of patients with RR IDH2-mutated AML treated with enasidenib (between 1/2018 and 6/2019) or other first-line (1 L) RR therapy (between 1/2016 and 7/2017). Progression-free survival (PFS) and overall survival (OS) were estimated by the Kaplan-Meier method, and adjusted risk of progression and death were estimated by multivariable Cox proportional hazard models. Among 124 patients treated with enasidenib and 76 patients treated with other 1 L RR therapy, overall response rate was higher among patients treated with enasidenib vs. other 1 L RR therapies (77% vs. 52%, p < 0.01). After a median follow-up of 9 and 6 months, median PFS was 8 months in enasidenib-treated patients and 5 months in patients receiving other 1 L RR therapy, respectively (adjusted HR=0.36, 95% CI: 0.23-0.57, p < 0.01). Median OS was 11 and 6 months in enasidenib-treated patients and patients receiving other 1 L RR therapy, respectively (adjusted HR=0.37, 95% CI: 0.22-0.60, p < 0.01). Fewer enasidenib-treated patients were hospitalized during 1 L RR therapy vs. those receiving other therapies (14% vs. 46%, p < 0.01). Results from this real-world study confirm the effectiveness of enasidenib among patients with IDH2-mutated RR AML and demonstrate that hospitalizations were significantly lower vs. other 1 L RR treatment in clinical practice.

Background: Cancer is the second leading cause of death in the United States. The incidence of emergency department (ED) visits by oncology patients has grown over the past years. Some ED visits are medically unnecessary and could be prevented with improved prevention measures. Objectives: To evaluate the incidence and causes of ED visits by cancer patients and evaluate outcomes and disposition of ED visits. Methods: This single-center, retrospective chart review was conducted in a tertiary medical hospital. We collected data using an electronic medical record and included oncology patients with active cancer who had ED visits from January 1, 2018, to December 31, 2018. Key data collection included baseline demographics; type of malignancy; main chief complaint; clinic visit history; current and past ED visits; treatment and supportive care data; and disposition status if admitted. Pregnant patients, patients without active cancer, and patients who received outpatient care at clinics other than the University of Arizona Cancer Center were excluded. Results: This chart review study screened 1,659 encounters and included 205 encounters. Approximately 70% of the encounters were solid tumor patients and 30% were hematologic malignancies. Nearly 50% of the patients with hematologic malignancies had preventable ED visits while 32.8% of solid tumor patients had preventable ED visits. The most common preventable ED visit reasons in both groups were pain, fever, nausea, vomiting, and dehydration. Almost 50% of the patients in both groups were hospitalized with a median length of stay of 3 days. The majority of admitted patients were discharged home in both the solid tumor (82.3%) and hematologic malignancy (83.8%) groups. Conclusion: This study showed that the rate of preventable visits was numerically higher in the hematologic cancer group compared with the solid tumor group. These findings highlight the potential need for implementing prevention measures in the future.
RESUMO
In oncology practices across the United States, biosimilars-highly similar versions of licensed, innovator (reference) biological medicines-are currently emerging as more affordable therapeutic options. Only after a rigorous product development program, during which a proposed biosimilar is analyzed and compared with its reference biologic to demonstrate comparable clinical efficacy, safety, and tolerability, is biosimilarity supported and licensure granted by the US Food and Drug Administration. Coincidentally, many advanced practitioners (APs) are finding themselves at the forefront of introducing monoclonal antibody (mAb) biosimilars in their oncology practice. Advanced practitioners are often tasked with building the confidence of colleagues and patients who may be unfamiliar with biosimilars, skeptical about integrating them, or have yet to consider mAb biosimilars as a viable and more sustainable cancer treatment option. With this responsibility comes a number of challenges that require APs to become knowledgeable about biosimilars and approaches to their implementation. This review aims to highlight the practical implications of streamlining the integration of biosimilar therapies in an oncology practice.
RESUMO
OBJECTIVES: Several chemoimmunotherapy and targeted treatment regimens are approved as front-line therapies in chronic lymphocytic leukemia. We estimated for the 10-year cost-effectiveness of these treatment regimens and the economic burden of following the estimated risk-stratified 21 040 patients with chronic lymphocytic leukemia diagnosed in 2020 for 10 years. METHODS: A Markov model with 7 exclusive health states was specified over a 10-year time horizon. Treatment effectiveness inputs were obtained from a novel network meta-analysis on the progression-free survival, overall survival curves, and time to next treatment. Costs and utilities inputs were included for each health state for each treatment and discounted at 3.0%/year. Life-years (LYs) and quality-adjusted LYs (QALYs) for each treatment were determined. Using the lowest cost regimen as reference, the incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR) were estimated. The 10-year per-patient cost was determined by risk status and by initial treatment. RESULTS: Venetoclax-plus-obinutuzumab was the lowest cost regimen, hence the reference. Superior in effectiveness to all chemoimmunotherapies, it was cost saving. With the highest effectiveness gains at 6.26 LYs and 5.01 QALYs and despite being the most expensive regimen ($1 298 638 per patient), acalabrutinib-plus-obinutuzumab yielded the best ICER ($409 343/LY gained) and ICUR ($501 236/QALY gained). The remaining ICERs of targeted therapies ranged from $512 101/LY gained to $793 236/LY gained and the ICURs from $579 737/QALY gained to $869 300/QALY gained. The 10-year postdiagnosis low/high (venetoclax-plus-obinutuzumab/acalabrutinib-plus-obinutuzumab) economic burden ranges were $42 690 to $98 665 for low-risk, $141 339 to $326 660 for intermediate-risk, and $273 650 to $632 453 for high-risk patients. CONCLUSIONS: Compared with venetoclax-plus-obinutuzumab, chemoimmunotherapies are associated with less health benefits at higher cost. The targeted therapies achieve greater benefits at higher cost.
