Are high drug prices for hematologic malignancies justified? A critical analysis

Disparities in mortality risk after diagnosis of hematological malignancies in 185 countries: A global data analysis

This study was to report proxy measures for mortality risk in patients with hematological malignancies across 185 countries globally and explore its association with their socioeconomic status and treatment. The incidence, mortality, and 5-year prevalence data were extracted from the GLOBOCAN database. The data regarding the human development index (HDI), gross national income (GNI), vulnerability index, and concordance with cancer Essential Medicines List (EML) were obtained from open-source reports. The ratio of mortality to 5-year-prevalence (MPR) and that of mortality to incidence (MIR) were calculated and age-standardized using Segi's world standard population. Finally, the possible associations were assessed using Pearson correlation analyses. In 2020, the global incidence, mortality, and 5-year prevalence of HMs were 1,278,362, 711,840, and 3,616,685, respectively. Global age-standardized MPR and MIR were 0.15 and 0.44, respectively; they varied significantly among 6 regions, 185 countries, 4 HM types, and 4 HDI groups worldwide. Older populations always had higher ratios. The correlation of MPRs and MIRs with HDI, GNI, and concordance with cancer EML was negative, whereas it was positive with the vulnerability index (lower was better). Increasing access to cancer drugs in resource-limited regions with a focus on vulnerable children may aid in reducing HM-related mortality risk.

Outcome of Philadelphia chromosome-positive chronic myeloid leukemia in the United States since the introduction of imatinib therapy-The Surveillance, Epidemiology, and End Results database, 2000-2019

BACKGROUND

Since the introduction of BCR::ABL1 tyrosine kinase inhibitors (TKIs) in 2000, the treatment of Philadelphia chromosome (Ph)-positive chronic myeloid leukemia (CML) has improved significantly.

METHODS

This study aimed to evaluate Ph-positive CML outcomes in the TKI therapy era, considering factors like age, ethnicity, and income. Using the Surveillance, Epidemiology, and End Results (SEER) database, 2857 patients with Ph-positive CML diagnosed from 2000 to 2019 were analyzed.

RESULTS

The overall 5-year survival rates in Ph-positive CML increased to above 80%, compared with pre-TKIs historical data reporting 5-year overall survival (OS) rates of less than 50%. The 5-year OS rate was 73% for patients diagnosed in 2000-2004, 82% in 2005-2009, and 78% in 2010-2014; the 4-year OS rate was 83% in 2015-2019. The 5-year OS rate for younger patients (<60 years old) was 88% in 2000-2009 and 90% in 2010-2019 (p value .426). In older patients (60+ years old), the 5-year OS rates were 64% and 65%, respectively (p value, .303). Lower household income was associated with inferior survival across the 2000-2019. These results are inferior to European studies where TKIs are universally available and affordable, and relative OS in CML is similar to age-matched normal populations.

CONCLUSIONS

Although the outcome of Ph-positive CML has improved significantly since 2000, the SEER data still shows differences in outcomes among patient subsets, some anticipated (worse OS in older patients accounted by the relative OS), but others that suggest less than universal access and affordability of this therapy (among poorer patients) in the United States.

Career disruption and limitation of financial earnings due to cancer

PURPOSE

This study investigated how cancer diagnosis and treatment lead to career disruption and, consequently, loss of income and depletion of savings.

DESIGN

This study followed a qualitative descriptive design that allowed us to understand the characteristics and trends of the participants.

METHOD

Patients recruited (n = 20) for this study were part of the University of Kansas Cancer Center patient advocacy research group (Patient and Investigator Voices Organizing Together). The inclusion criteria were that participants must be cancer survivors or co-survivors, be aged 18 years or older, be either employed or a student at the time of cancer diagnosis, have completed their cancer treatment, and be in remission. The responses were transcribed and coded inductively to identify themes. A thematic network was constructed based on those themes, allowing us to explore and describe the intricacies of the various themes and their impacts.

RESULTS

Most patients had to quit their jobs or take extended absences from work to handle treatment challenges. Patients employed by the same employer for longer durations had the most flexibility to balance their time between cancer treatment and work. Essential, actionable items suggested by the cancer survivors included disseminating information about coping with financial burdens and ensuring that a nurse and financial navigator were assigned to every cancer patient.

CONCLUSIONS

Career disruption is common among cancer patients, and the financial burden due to their career trajectory is irreparable. The financial burden is more prominent in younger cancer patients and creates a cascading effect that financially affects close family members.

Financial burden among cancer patients: A national-level perspective

BACKGROUND

This research study aimed to evaluate the financial burden among older cancer patients and its corresponding risk factors. Factors such as increasing treatment costs and work limitations often lead cancer patients to bankruptcy and poor quality of life. These consequences, in turn, can cause higher mortality rates among these patients.

METHODS

This retrospective cohort study utilized data from the Health Retirement Study (HRS), conducted by the University of Michigan (N = 18,109). Eligible participants had responses captured from years 2002 to 2016. Participants were classified according to any self-reported cancer diagnosis (yes or no) and were compared on the basis of financial, work, and health-related outcomes. Propensity score (PS) matching was applied to reduce the effects of potential confounding factors. Also only, individuals with an age ≥50 and ≤85 during Wave 6 were retained.

RESULTS

Multivariate analysis with random effects revealed several indicators of financial burden when comparing participants with a cancer diagnosis to those with no history of cancer. Mean out-of-pocket costs associated with a cancer diagnosis were $1058 higher when compared to participants with no history of cancer, suggesting that even cancer patients with insurance coverage faced out-of-pocket costs. Respondents with cancer patients had higher odds of encountering financial hardship if they are facing Work Limitations (OR = 2.714), Regular use of Medications (OR = 2.518), Hospital Stays (OR = 2.858), Declining Health (OR = 2.349), or were being covered under government health insurance (OR = 5.803) than respondents who did not have cancer, or suffered from mental health issues such as Depression (OR = 0.901).

CONCLUSION

Cancer patients contend with increasing financial costs during their treatment. However, most newly diagnosed patients are not aware of these costs and are given few resources to handle them.

The influence of drug prices, new availability of inexpensive generic imatinib, new approvals, and post-marketing research on the treatment of chronic myeloid leukaemia in the USA

Several research and market developments in the past 5 years could influence front-line and subsequent-line strategies in chronic myeloid leukaemia. These developments include the increased availability of effective and safe generic imatinib at affordable prices, studies showing that doses of tyrosine kinase inhibitors (TKIs) lower than the approved dose are effective and less toxic, studies showing that dose-adjusted ponatinib therapy at a reduced dose is effective and substantially safer than approved doses, and the approval of asciminib as third-line therapy in 2021. With the availability of an affordable generic imatinib, all patients with chronic myeloid leukaemia globally should be able to access a lifetime supply. The availability of reduced-dose schedules of generic second-generation TKIs, which are less toxic and produce faster deep molecular response than imatinib, might make them more appealing to use as front-line therapy. In the subsequent-line setting, the role of different TKIs as second, third, and later lines of therapy depends on the evolving front-line use. Dose-adjusted ponatinib schedules have shown better efficacy and safety with long-term follow-up. Ponatinib is the favoured therapy for patients with second-generation-TKI resistance or chronic myeloid leukaemia with 944C→T (Thr315Ile)-mutated BCR-ABL1. Studies of asciminib are needed in larger numbers of patients and with longer follow-up than has been done previously to better assess its comparative efficacy, safety, and survival data (vs ponatinib). The role of third-generation TKIs as second-line therapy following front-line resistance to second-generation TKIs needs to be evaluated. New and mature data with TKI therapy in chronic myeloid leukaemia are producing observations that encourage continuous discussion of the optimal treatment recommendations and frameworks in chronic myeloid leukaemia.

Systematic review of costs and cost-effectiveness of treatment for relapsed/refractory acute leukaemia in children and young adults

INTRODUCTION

Survival outcomes of children with relapsed/refractory (r/r) acute leukaemia remain poor. Novel expensive treatments have been developed to improve their outcomes, yet, limited evidence exists about cost-effectiveness of alternative treatment strategies.

AREAS COVERED

A systematic review was conducted to summarize the health-economic evidence about costs/cost-effectiveness of treating r/r acute leukaemia in children/young adults. We searched Medline, Embase, and Cochrane databases until August 13^th, 2021. Eligible articles included peer-reviewed original studies addressing r/r paediatric/young-adult acute lymphoblastic leukaemia (ALL), and acute myeloid leukaemia (AML). Quality assessment was conducted using Consolidated Health Economics Evaluation Reporting Standards (CHEERS) checklist.

EXPERT OPINION

The majority of papers focused on CAR-T cell therapy, which is still a novel treatment for r/r ALL, and was found to be cost-effective, yet, there remain concerns over its long-term effectiveness, affordability, and equity in access. The next best treatment option is Blinatumomab, followed by Clofarabine therapy, whereas FLA-IDA salvage chemotherapy provides least value for money. The quality of evidence is moderate to high, with limited generalizability of findings due to high variability in outcomes obtained from modelling studies. Limited studies evaluated r/r AML. We provide recommendations to deliver cost-effective treatments in real-world contexts, with implications for healthcare policy and practice.

Health-related quality of life using EQ-5D among chronic myeloid leukaemia patients in health centres in Klang Valley, Malaysia

Chronic Myeloid Leukaemia (CML) responds well with the targeted therapy drugs, Tyrosine Kinase Inhibitors (TKI), that give potentially long-term disease control for the patients. The objective of this study was to determine the disease burden and factors influencing the health-related quality of life (HRQoL) and health status of CML patients in Klang Valley, Malaysia. CML patients were recruited from haematological outpatient clinics in health centres in Klang Valley, Malaysia. A semi-guided self-administered questionnaire was used. HRQoL was measured by EQ-5D utility value and health status was by visual analogue score (VAS). Logistic regression analysis was conducted to determine the factors influencing HRQoL and health status. A total of 221 respondents participated, where more than half were Malay (56.6%), male (53.4%), and an Imatinib user (68.8%). Majority were diagnosed at the chronic phase (89.5%). The mean age of diagnosis was 41 years old. Significant determinant associated with HRQoL was age of diagnosis. These factors had no significant effect on the HRQoL of these patients regardless of types of TKI used and initial phase of CML. The overall HRQoL of CML patients were comparable to, if not higher, than the general population. Any TKI that was good enough to eliminate disease symptoms and erase patient's worries, can possibly make CML patients have a better quality of life than typical cancer patients and even the general population.

Incorporating Value-Based Care Into Oncology

Value-based care within insurance design utilizes evidence-based medicine as a means of defining high-value versus low-value diagnostics and treatments. The goals of value-based care are to shift spending and coverage toward high-value care and reduce the use of low-value practices. Within oncology, several value-based methods have been proposed and implemented. We review value-based care being used within oncology, including defining the value of oncology drugs through frameworks, clinical care pathways, alternative payment models including the Oncology Care Model, value-based insurance design, and reducing low-value care including the Choosing Wisely initiatives.

Readying students for careers in industry: A guided inquiry activity to prepare students for success in biotechnology and pharmaceutical industry positions

While science students are well prepared for careers in biotechnology and pharmaceutical sciences in terms of technical expertise and critical thinking, they rarely have an opportunity to practice the due diligence required for success in industry in their coursework. This includes framing their expertise as solutions to challenges a company may be experiencing, an important skill for the interview process. As most academics have not applied for positions in industry, they may feel ill equipped to help students practice the important skills of framing their expertise within company goals and to discuss the business and financial concepts relevant to careers in scientific industry. Here, we describe an educational activity first developed by a leader in the biotech/pharmaceutical industry that was modified and given educational context by an academic in a class of upper-level undergraduate and graduate students. In this guided inquiry activity, students were instructed to select a start-up company in their field-ideally one to which they intended to apply for a job. Students were empowered by scaffolded hands-on exercises to research the company's scientific focus and finances, and to frame how their expertise could help companies achieve stated goals. Students compiled and delivered their research as an in-class presentation.

Value Frameworks: Adaptation of Korean Versions of Value Frameworks for Oncology

This study sought to adapt the existing value framework (VF) to produce a reliable and valid Korean oncology VF. Two VFs developed by The American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) were selected for examination in the present study. Forward and backward translations were conducted for six high-priced drugs indicated for non-small-cell lung cancer and multiple myeloma. Inter-rater reliability was measured based on the intraclass correlation coefficient (ICC) and variation was described using the coefficient of variation. The relative weights of factors critically considered by Korean oncologists were derived following the analytic hierarchy process (AHP), and focus group interviews (FGIs) were used to obtain qualitative data regarding the applications of these two VFs in the Korean setting. The ICCs of the Korean VFs were 0.895 (0.654-0.983) for ASCO and 0.726 (0-0.982) for ESMO translations, suggesting excellent reliability for ASCO and good reliability for ESMO. AHP demonstrated that clinical benefit has the highest priority, which is consistent with the ASCO VF. The FGIs suggested that the result for AHP is acceptable and that both ESMO and ASCO VFs should be used complementarily. Although further evaluation with a larger sample size is needed, the Korean versions of ESMO/ASCO VFs are valid and reliable tools and are acceptable to Korean stakeholders, yet they should be applied with caution.

Long-Term Effectiveness and Cost Effectiveness of Multiple Myeloma Treatment Strategies for Elderly Transplant-Ineligible Patients in Serbia

Introduction

Evidence on long-term effectiveness and cost effectiveness of treatment sequences for multiple myeloma (MM) is sparse. We used published data and country-specific data to assess the cost effectiveness of four-line treatment sequences for elderly transplant-ineligible patients with MM in Serbia.

Method

We developed a Markov cohort model to compare long-term effectiveness and cost effectiveness of five sequential MM treatment alternatives from the perspective of the national healthcare provider. Effectiveness parameters on progression, mortality and adverse events were extracted from published clinical trials. Costs were based on price lists of the National Health Insurance Fund. We compared life expectancy, costs, and incremental cost-effectiveness ratios among alternative courses of action. The model was analyzed over a lifelong time horizon applying a 3% annual discount rate for effectiveness outcomes and costs. Robustness of the model was tested in multiple deterministic sensitivity analyses.

Results

The sequences were defined by the frontline treatment: MPT (melphalan-prednisone-thalidomide), MPV (melphalanprednisone-bortezomib), CTD (cyclophosphamide-thalidomide-dexamethasone), VCD (bortezomib-cyclophosphamidedexamethasone) and BP (bendamustine-prednisone). MPV sequence resulted in the highest remaining life expectancy (4.76 life years). Cost-effectiveness analysis resulted in three non-dominated strategies: MPT, VCD, and MPV sequences, with an incremental cost-effectiveness ratio of EUR 35,300 per life-year gained (LYG) for VCD and EUR 47,200/LYG for MPV relative to MPT.

Conclusion

MPV sequence was the most effective in terms of life expectancy for elderly transplant-ineligible MM patients in Serbia. Bortezomib-based strategies would be recommended for the frontline treatment of patients with MM in Serbia if the willingness-to-pay threshold is around EUR 35,000-60,000/LYG.

Managing chronic myeloid leukemia for treatment-free remission: a proposal from the GIMEMA CML WP

Several papers authored by international experts have proposed recommendations on the management of BCR-ABL1+ chronic myeloid leukemia (CML). Following these recommendations, survival of CML patients has become very close to normal. The next, ambitious, step is to bring as many patients as possible into a condition of treatment-free remission (TFR). The Gruppo Italiano Malattie EMatologiche dell'Adulto (GIMEMA; Italian Group for Hematologic Diseases of the Adult) CML Working Party (WP) has developed a project aimed at selecting the treatment policies that may increase the probability of TFR, taking into account 4 variables: the need for TFR, the tyrosine kinase inhibitors (TKIs), the characteristics of leukemia, and the patient. A Delphi-like method was used to reach a consensus among the representatives of 50 centers of the CML WP. A consensus was reached on the assessment of disease risk (EUTOS Long Term Survival [ELTS] score), on the definition of the most appropriate age boundaries for the choice of first-line treatment, on the choice of the TKI for first-line treatment, and on the definition of the responses that do not require a change of the TKI (BCR-ABL1 ≤10% at 3 months, ≤1% at 6 months, ≤0.1% at 12 months, ≤0.01% at 24 months), and of the responses that require a change of the TKI, when the goal is TFR (BCR-ABL1 >10% at 3 and 6 months, >1% at 12 months, and >0.1% at 24 months). These suggestions may help optimize the treatment strategy for TFR.

Therapeutic Advances in the Management of Smoldering Myeloma

BACKGROUND

The International Myeloma Working Group has defined smoldering multiple myeloma (SMM) as the presence of 10%-60% plasma cells in the bone marrow and M-protein (IgG, IgA) ≥3 g/dL without end-organ damage (an increased calcium level, renal failure, anemia, and destructive bone lesions).

AREAS OF UNCERTAINTY

Patients considered to have SMM should not have any myeloma-defining events or amyloidosis. Different risks factors classify SMM into low-, intermediate-, or high-risk categories. The rate of progression from SMM to symptomatic myeloma is ∼10% per year during the first 5 years of diagnosis. SMM requires frequent follow-up ∼every 3 months during the first 5 years as compared to monoclonal gammopathy of undermined significance, which usually requires follow-up every 6-12 months after the first year of diagnosis.

DATA SOURCES

A literature search was performed from electronic bibliographic databases: MEDLINE (Ovid SP/PubMed), EMBASE, the Cochrane Library (Cochrane Database of Systematic Reviews), and Cochrane Central Register of Controlled Trials and from annual meeting abstracts from inception to May 2017.

THERAPEUTIC ADVANCES

This review presents the literature and available data that support or do not support early treatment of high-risk SMM (HR-SMM) and provides evidence-based recommendations for management of SMM patients. Despite emerging data recommending early treatment of HR-SMM, we predict the SMM category may disappear in the near future and patients will be diagnosed with either multiple myeloma or monoclonal gammopathy of undermined significance.

CONCLUSIONS

Success with early therapy trials for HR-SMM is largely due to patients meeting current criteria for multiple myeloma that may have been classified as SMM and, therefore, benefitted from therapy. Based on current practices and the literature, SMM should be managed with close follow-up. Based on available data, we suggest SMM to only be treated in clinical trial settings.

Cancer History, Health Insurance Coverage, and Cost-Related Medication Nonadherence and Medication Cost-Coping Strategies in the United States

OBJECTIVES

To evaluate the relationship between cancer history and cost-related medication nonadherence (CRN) as well as cost-coping strategies, by health insurance coverage.

METHODS

We used the 2013 to 2016 National Health Interview Survey to identify adults aged 18 to 64 years with (n = 3599) and without (n = 56 909) a cancer history. Cost-related changes in medication use included (1) CRN, measured as skipping, taking less, or delaying medication because of cost, and (2) cost-coping strategies, measured as requesting lower cost medication or using alternative therapies to save money. Separate multivariable logistic regressions were used to calculate the adjusted odds ratios (AORs) of CRN and cost-coping strategies associated with cancer history, stratified by insurance.

RESULTS

Cancer survivors were more likely than adults without a cancer history to report CRN (AOR 1.26; 95% confidence interval [CI] 1.10-1.43) and cost-coping strategies (AOR 1.10; 95% CI 0.99-1.19). Among the privately insured, the difference in CRN by cancer history was the greatest among those enrolled in high-deductible health plans (HDHPs) without health savings accounts (HSAs) (AOR 1.78; 95% CI 1.30-2.44). Among adults with HDHP and HSA, cancer survivors were less likely to report cost-coping strategies (AOR 0.62; 95% CI 0.42-0.90). Regardless of cancer history, CRN and cost-coping strategies were the highest for those uninsured, enrolled in HDHP without HSA, and without prescription drug coverage under their health plan (all P<.001).

CONCLUSIONS

Cancer survivors are prone to CRN and more likely to use cost-coping strategies. Expanding options for health insurance coverage, use of HSAs for those with HDHP, and enhanced prescription drug coverage may effectively address CRN.

Cost, Value, and Financial Hardship in Cancer Care: Implications for Pediatric Oncology

Cancer care in the United States faces a perfect storm: an aging population and expected increased cancer incidence, growing numbers of cancer survivors with ongoing care needs, and continued scientific advancements, offering extraordinary promise at extraordinary cost. How, then, do we as pediatric oncologists engage in the dialogue about cancer cost considerations? The purpose of this article and its accompanying session presented at the 2018 ASCO Annual Meeting is to introduce concepts of cost, value, and financial hardship. In the first section, we will provide an overview of principles of health economics, including components of cost, time horizon consideration, discounting, and methods to calculate incremental cost-effectiveness among therapeutic approaches. We will then introduce the value framework being debated in adult oncology and offer potential opportunities for its application in pediatric oncology. In the second section, we will describe the integration of the cost-effectiveness paradigm in an ongoing pediatric clinical trial, including design and analytic considerations. In the third section, we will shift away from cost to the health care system to cost to the patient, which is also termed "financial toxicity" or "financial hardship," focusing on the ongoing burden of cost on survivors of childhood cancer. Our goal is to provide our readers with the vocabulary and understanding of this complex and often thorny debate so that they can be active participants and informed advocates for their patients.

Chronic myeloid leukemia: 2018 update on diagnosis, therapy and monitoring

DISEASE OVERVIEW

Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm with an incidence of 1-2 cases per 100 000 adults. It accounts for approximately 15% of newly diagnosed cases of leukemia in adults.

DIAGNOSIS

CML is characterized by a balanced genetic translocation, t(9;22)(q34;q11.2), involving a fusion of the Abelson gene (ABL1) from chromosome 9q34 with the breakpoint cluster region (BCR) gene on chromosome 22q11.2. This rearrangement is known as the Philadelphia chromosome. The molecular consequence of this translocation is the generation of a BCR-ABL1 fusion oncogene, which in turn translates into a BCR-ABL1 oncoprotein. Frontline therapy: Four tyrosine kinase inhibitors (TKIs), imatinib, nilotinib, dasatinib, and bosutinib are approved by the United States Food and Drug Administration for first-line treatment of patients with newly diagnosed CML in chronic phase (CML-CP). Clinical trials with second generation TKIs reported significantly deeper and faster responses; this has not translated into improved long-term survival, because of the availability of effective salvage therapies. Salvage therapy: For patients who fail frontline therapy, second-line options include second and third generation TKIs. Second and third generation TKIs, although potent and selective, exhibit unique pharmacological profiles and response patterns relative to different patient and disease characteristics, such as patients' comorbidities, disease stage, and BCR-ABL1 mutational status. Patients who develop the T315I "gatekeeper" mutation display resistance to all currently available TKIs except ponatinib. Allogeneic stem cell transplantation remains an important therapeutic option for patients with CML-CP who have failed at least 2 TKIs, and for all patients in CML advanced phases.

Challenges in the Clinical Application of the American Society of Clinical Oncology Value Framework: A Medicare Cost-Benefit Analysis in Chronic Lymphocytic Leukemia

PURPOSE

The ASCO Value Framework calculates the value of cancer therapies. Given costly novel therapeutics for chronic lymphocytic leukemia, we used the framework to compare net health benefit (NHB) and cost within Medicare of all regimens listed in the National Comprehensive Cancer Network (NCCN) guidelines.

METHODS

The current NCCN guidelines for chronic lymphocytic leukemia were reviewed. All referenced studies were screened, and only randomized controlled prospective trials were included. The revised ASCO Value Framework was used to calculate NHB. Medicare drug pricing was used to calculate the cost of therapies.

RESULTS

Forty-nine studies were screened. The following observations were made: only 10 studies (20%) could be evaluated; when comparing regimens studied against the same control arm, ranking NHB scores were comparable to their preference in guidelines; NHB scores varied depending on which variables were used, and there were no clinically validated thresholds for low or high values; treatment-related deaths were not weighted in the toxicity scores; and six of the 10 studies used less potent control arms, ranked as the least-preferred NCCN-recommended regimens.

CONCLUSION

The ASCO Value Framework is an important initial step to quantify value of therapies. Essential limitations include the lack of clinically relevant validated thresholds for NHB scores and lack of incorporation of grade 5 toxicities/treatment-related mortality into its methodology. To optimize its application for clinical practice, we urge investigators/sponsors to incorporate and report the required variables to calculate the NHB of regimens and encourage trials with stronger comparator arms to properly quantify the relative value of therapies.

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.

Cost-effectiveness of kinase inhibitors for hematologic malignancies: a systematic and critical review

INTRODUCTION

Several genetic disruptions lead to constitutive activation of those kinases leukemic cells depend on for survival and proliferation. Kinase inhibitors (KI) are major therapeutic innovations for chronic myeloid leukemia (CML), chronic lymphoid leukemia (CLL) and myelofibrosis (MF) providing a relevant improvement of quality-adjusted survival in patients with high-risk or refractory disease. CML patients are being treated with first-generation KI imatinib since many years, achieving expected survivals longer than 10 years. Second- and third generations KIs, such as nilotinib, dasatinib, ponatinib and bosutinib, recently expanded the therapeutic yield for CML and treatment discontinuation in patients with persistent deep molecular response is being pursued. Areas covered: This review summarizes available evidence on economic analyses of KI treatments for CML, CLL and MF aimed at identifying the key determinants of KI cost-effectiveness. Expert commentary: On converse, specific KIs for CLL and MF patients have been marketed only in the last few years. Ibrutinib and idelalisib allowed to improve the outcomes of relapsed/refractory CLL and of patients with poor genetic features, while the first-in-class JAK2 inhibitor ruxolitinib allowed to improve symptoms of advanced MF patients and to prolong survival in responders. In the current situation of healthcare budget restrictions worldwide, the value for cost of the above KIs has been questioned.

Economic Burden of Chronic Lymphocytic Leukemia in the Era of Oral Targeted Therapies in the United States

Purpose Oral targeted therapies represent a significant advance for the treatment of patients with chronic lymphocytic leukemia (CLL); however, their high cost has raised concerns about affordability and the economic impact on society. Our objective was to project the future prevalence and cost burden of CLL in the era of oral targeted therapies in the United States. Methods We developed a simulation model that evaluated the evolving management of CLL from 2011 to 2025: chemoimmunotherapy (CIT) as the standard of care before 2014, oral targeted therapies for patients with del(17p) and relapsed CLL from 2014, and for first-line treatment from 2016 onward. A comparator scenario also was simulated where CIT remained the standard of care throughout. Disease progression and survival parameters for each therapy were based on published clinical trials. Results The number of people living with CLL in the United States is projected to increase from 128,000 in 2011 to 199,000 by 2025 (55% increase) due to improved survival; meanwhile, the annual cost of CLL management will increase from $0.74 billion to $5.13 billion (590% increase). The per-patient lifetime cost of CLL treatment will increase from $147,000 to $604,000 (310% increase) as oral targeted therapies become the first-line treatment. For patients enrolled in Medicare, the corresponding total out-of-pocket cost will increase from $9,200 to $57,000 (520% increase). Compared with the CIT scenario, oral targeted therapies resulted in an incremental cost-effectiveness ratio of $189,000 per quality-adjusted life-year. Conclusion The increased benefit and cost of oral targeted therapies is projected to enhance CLL survivorship but can impose a substantial financial burden on both patients and payers. More sustainable pricing strategies for targeted therapies are needed to avoid financial toxicity to patients.

Evolution of Management and Outcomes in Waldenström Macroglobulinemia: A Population-Based Analysis

INTRODUCTION

Waldenström macroglobulinemia/lymphoplasmacytic lymphoma (WM) is a rare lymphoma affecting older patients. Its management largely relies on small phase II trials and it is unclear how their results translate into clinical practice in the community.

METHOD

We evaluated changes in the presentation, management, and survival among 2,666 Medicare beneficiaries diagnosed with WM between 1994 and 2011, using Medicare claims linked to Surveillance, Epidemiology and End Results data.

RESULTS

Prevalence of transfusions, anemia, thrombocytopenia, and neuropathy at diagnosis significantly increased over time, whereas the use of plasmapheresis was low (2.5%) and stable. The proportion of patients starting chemotherapy within 1 year of WM diagnosis increased from 39% in 1994 to 62% in 2011 (p < .0001). Treatments based on classic alkylators and purine analogs predominated in the 1990s, but were quickly replaced by rituximab-containing regimens after 2000. Rituximab monotherapy has been prescribed for >50% of patients since 2004, and combination chemoimmunotherapy for a further 30%. Most patients initiating multiagent regimens in 2012-2013 received rituximab with bortezomib or bendamustine. These changes were accompanied by significant improvements in overall and WM-related survival, but also by a significant increase in cost of chemotherapy. Mean Medicare payments for chemotherapy drugs accrued in the first year of treatment rose from $9,464 in 1994-2000 to $29,490 after 2008.

CONCLUSION

Hematologists have rapidly adopted innovative, expensive therapies for WM before completion of randomized trials. This underscores the need to assess the comparative value of such therapies in rare malignancies through a combination of clinical and observational data.

IMPLICATIONS FOR PRACTICE

Most older patients with Waldenström macroglobulinemia currently treated in the U.S. receive rituximab as monotherapy or in combination with bortezomib or bendamustine. Newly designed trials should consider control arms aligned with this prevalent real-life standard. Compared with the 1990s, patients diagnosed according to current criteria are more likely to have anemia or neuropathy, or to receive early chemotherapy, but only 2.5% require plasmapheresis at diagnosis. The incremental clinical value of newly introduced agents needs to be assessed through a combination of clinical and health services research, taking into consideration their associated survival benefits, toxicities, and associated costs of care.

Systematic Review of Modelling Approaches for the Cost Effectiveness of Hepatitis C Treatment with Direct-Acting Antivirals

BACKGROUND

New direct-acting antivirals (DAAs) are highly effective for hepatitis C virus (HCV) treatment. However, their prices have been widely debated. Decision-analytic models can project the long-term value of HCV treatment. Therefore, understanding of the methods used in these models and how they could influence results is important.

OBJECTIVE

Our objective was to describe and systematically review the methodological approaches in published cost-effectiveness models of chronic HCV treatment with DAAs.

DATA SOURCES

We searched several electronic databases, including Medline, Embase and EconLit, from 2011 to 2015.

STUDY ELIGIBILITY

Study selection was performed by two reviewers independently. We included any cost-effectiveness analysis comparing DAAs with the old standard of care for HCV treatment. We excluded non-English-language studies and studies not reporting quality-adjusted life-years.

STUDY APPRAISAL AND SYNTHESIS METHOD

One reviewer collected data and assessed the quality of reporting, using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement. Another reviewer crosschecked the abstracted information. The development methods of the included studies were synthetized on the basis of good modelling practice recommendations.

RESULTS

Review of 304 citations revealed 36 cost-effectiveness analyses. The reporting quality scores of most articles were rated as acceptable, between 67 and 100 %. The majority of the studies were conducted in Europe (50 %), followed by the USA (44 %). Fifty-six percent of the 36 studies evaluated the cost effectiveness of HCV treatment in both treatment-naive and treatment-experienced patients, 97 % included genotype 1 patients and 53 % evaluated the cost effectiveness of second-generation or oral DAAs in comparison with the previous standard of care or other DAAs. Twenty-one models defined health states in terms of METAVIR fibrosis scores. Only one study used a discrete-event simulation approach, and the remainder used state-transition models. The time horizons varied; however, 89 % of studies used a lifetime horizon. One study was conducted from a societal perspective. Thirty-three percent of studies did not conduct any model validation. We also noted that none of the studies modelled HCV treatment as a prevention strategy, 86 % of models did not consider the possibility of re-infection with HCV after successful treatment, 97 % of studies did not consider indirect economic benefits resulting from HCV treatment and none of the studies evaluating oral DAAs used real-world data.

LIMITATIONS

The search was limited by date (from 1 January 2011 to 8 September 2015) and was also limited to English-language and published reports.

CONCLUSIONS

Most modelling studies used a similar modelling structure and could have underestimated the value of HCV treatment. Future modelling efforts should consider the benefits of HCV treatment in preventing transmission, extra-hepatic and indirect economic benefits of HCV treatment, real-world cost-effectiveness analysis and cost effectiveness of HCV treatment in low- and middle-income countries.

Targeted therapy: Generic imatinib - impact on frontline and salvage therapy for CML

Imatinib has revolutionized the treatment of chronic myeloid leukaemia (CML). In 2016, generic imatinib will be introduced into the US market. We analyse the potential impact of this new product on patient care and optimal CML therapy, and comment on the effect that distorted cancer drug pricing in the USA will have on treatment for patients with limited therapeutic options.

[Anticancer drugs: Which prices for therapeutic innovations?]

The expanding knowledge of the biological mechanisms underlying tumor development made it possible the recent emergence of new therapeutic approaches that are considered as undoubtedly innovative. Yet, to define and to evaluate the magnitude of a drug innovation require an examination of its intrinsic drug properties, medical utility as well as its mode of emergence. Recently, international academic societies, such as ESMO and ASCO, have proposed practical tools that may help quantifying the medical value of a given innovation. Currently, the sustained flux of therapeutic innovations in oncology is associated with an unprecedented growth of costs, the actual determinants of which remain under debate, but raising the critical issue of drugs pricing, and their potential individual or societal "financial toxicity".

A retrospective analysis of treatment-related hospitalization costs of pediatric, adolescent, and young adult acute lymphoblastic leukemia

This retrospective study examined the longitudinal hospital outcomes (costs adjusted for inflation, hospital days, and admissions) associated with the treatment of pediatric, adolescent, and young adult acute lymphoblastic leukemia (ALL). Patients between one and 26 years of age with newly diagnosed ALL, who were treated at Primary Children's Hospital (PCH) in Salt Lake City, Utah were included. Treatment and hospitalization data were retrieved from system-wide cancer registry and enterprise data warehouse. PCH is a member of the Children's Oncology Group (COG) and patients were treated on, or according to, active COG protocols. Treatment-related hospital costs of ALL were examined by computing the average annual growth rates (AAGR). Longitudinal regressions identified patient characteristics associated with costs. A total of 505 patients (46.9% female) were included. The majority of patients had B-cell lineage ALL, 6.7% had T-ALL, and the median age at diagnosis was 4 years. Per-patient, first-year ALL hospitalization costs at PCH rose from $24,197 in 1998 to $37,924 in 2012. The AAGRs were 6.1, 13.0, and 7.6% for total, pharmacy, and room and care costs, respectively. Average days (AAGR = 5.2%) and admissions (AAGR = 3.8%) also demonstrated an increasing trend. High-risk patients had 47% higher costs per 6-month period in the first 5 years from diagnosis than standard-risk patients (P < 0.001). Similarly, relapsed ALL and stem cell transplantations were associated with significantly higher costs than nonrelapsed and no transplantations, respectively (P < 0.001). Increasing treatment-related costs of ALL demonstrate an area for further investigation. Value-based interventions such as identifying low-risk fever and neutropenia patients and managing them in outpatient settings should be evaluated for reducing the hospital burden of ALL.

Considering baseline factors and early response rates to optimize therapy for chronic myeloid leukemia in chronic phase

Multiple BCR-ABL tyrosine kinase inhibitors (TKIs) are available for the treatment of chronic myeloid leukemia in chronic phase (CML-CP), and several baseline and on-treatment predictive factors have been identified that can be used to help guide TKI selection for individual patients. In particular, early molecular response (EMR; BCR-ABL ≤10% on the International Scale at 3 months) has become an accepted benchmark for evaluating whether patients with CML-CP are responding optimally to frontline TKI therapy. Failure to achieve EMR is considered an inadequate initial response according to the National Comprehensive Cancer Network guidelines and a warning response according to the European LeukemiaNet recommendations. Here we review data supporting the importance of achieving EMR for improving patients' long-term outcomes and discuss key considerations for selecting a frontline TKI in light of these data. Because a higher proportion of patients achieve EMR with second-generation TKIs such as nilotinib and dasatinib than with imatinib, these TKIs may be preferable for many patients, particularly those with known negative prognostic factors at baseline. We also discuss other considerations for frontline TKI choice, including toxicities, cost-effectiveness, and the emerging goals of deep molecular response and treatment-free remission.

Value of innovation for hematologic malignancies

BACKGROUND

Several novel drugs are dramatically improving both lifespan and quality-of-life of patients with blood cancers.

AIM

Prolonged disease duration and increased treatment costs for hematologic malignancies impose a relevant economic burden onto healthcare services, despite the low incidence of blood cancers. Therefore, an appropriate paradigm for valuing 'innovation' is urgently required in order to refine pricing and reimbursement decisions. Cost-per-QALY-gained is still the standard metric for assessing the 'incremental' value of new drugs; however, the high number of 'comparator' therapies and the huge variety of treatment sequences make plain two-treatment comparisons sub-optimal, while multiple-treatment and multiple-sequence comparisons require complex and less-transparent decision models. A repository of standard backbones for decision models might allow benchmarking and comparability among cost-effectiveness analyses; however, an international effort is required to build it up.

RESULTS

Deontology recommends that hematologists act in optimizing healthcare resources while preserving patient-physician alliance, but clinical practice guidelines do not support doctors in balancing cost against clinical outcomes. Decision models of chronic blood cancers unexpectedly proved that cost might be an appropriate value for innovation if treatments avoided severe toxicity and further lines of treatments, despite the eventually long duration of treatment and the competing risk of death due to comorbidity and old age.

CONCLUSION

The improved transparency of decision models allows sharing of relevant structural and analytic parameters (i.e., time horizon, comparator treatments, hierarchy of end-point, assumptions, source of data, sub-group analyses) by stakeholders, physicians and patients, making health economics a noble 'translator' of values for innovation.
