RESUMEN

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV)'s impact on work loss remains poorly described. We evaluated associations between the duration of CINV episodes, CINV-related work loss (CINV-WL), and CINV-related activity impairment (CINV-AI) in patients with breast cancer receiving highly emetogenic chemotherapy. METHODS: We analyzed data from a prospective CINV prophylaxis trial of netupitant/palonestron and dexamethasone for patients receiving an anthracycline and cyclophosphamide (AC) for breast cancer (NCT0340371). Over the observed CINV duration (0-5 days), we analyzed patient-reported CINV-WL and CINV-AI for the first two chemotherapy cycles. We categorized patients as having either extended (≥ 3 days) or short (1-2 days) CINV duration and quantified its impact on work using the Work Productivity and Activity Impairment Questionnaire (WPAI). RESULTS: Overall, we captured data for 792 cycles in 402 women, including 136 (33.8%) employed patients with 35.3% reporting CINV. Of those with CINV, patients reported CINV-WL in 26 cycles and CINV-AI in 142 cycles. Of those with CINV, 55.3% of extended CINV cycles experienced CINV-WL compared to 16.7% of short CINV cycles (p < 0.001). The relative risk of CINV-WL between extended and short CINV was 3.32 (p < 0.01) for employed patients. The mean difference in CINV-AI scores (higher = worse) between extended and short duration CINV was 5.0 vs. 3.0 (p < 0.001). CONCLUSION: Extended (≥ 3 days) CINV was associated with more than triple the risk of CINV-WL and higher CINV-AI compared with short CINV.

RESUMEN

Background Many patients with heart failure (HF) have severely reduced ejection fraction but do not meet threshold for consideration of advanced therapies (ie, stage D HF). The clinical profile and health care costs associated with these patients in US practice is not well described. Methods and Results We examined patients hospitalized for worsening chronic heart failure with reduced ejection fraction ≤40% from 2014 to 2019 in the GWTG-HF (Get With The Guidelines-Heart Failure) registry, who did not receive advanced HF therapies or have end-stage kidney disease. Patients with severely reduced EF defined as EF ≤30% were compared with those with EF 31% to 40% in terms of clinical profile and guideline-directed medical therapy. Among Medicare beneficiaries, postdischarge outcomes and health care expenditure were compared. Among 113 348 patients with EF ≤40%, 69% (78 589) had an EF ≤30%. Patients with severely reduced EF ≤30% tended to be younger and were more likely to be Black. Patients with EF ≤30% also tended to have fewer comorbidities and were more likely to be prescribed guideline-directed medical therapy ("triple therapy" 28.3% versus 18.2%, P<0.001). At 12-months postdischarge, patients with EF ≤30% had significantly higher risk of death (HR, 1.13 [95% CI, 1.08-1.18]) and HF hospitalization (HR, 1.14 [95% CI, 1.09-1.19]), with similar risk of all-cause hospitalizations. Health care expenditures were numerically higher for patients with EF ≤30% (median US$22 648 versus $21 392, P=0.11). Conclusions Among patients hospitalized for worsening chronic heart failure with reduced ejection fraction in US clinical practice, most patients have severely reduced EF ≤30%. Despite younger age and modestly higher use of guideline-directed medical therapy at discharge, patients with severely reduced EF face heightened postdischarge risk of death and HF hospitalization.

RESUMEN

BACKGROUND: The relationship between CINV duration and recurrence in subsequent cycles is largely unstudied. Our objective was to determine if patients experiencing CINV in their first cycle of chemotherapy (C1) would face increased risk of CINV in later cycles and whether the duration of the CINV would predict increased risk of recurrence. PATIENTS AND METHODS: Using data from a previously reported phase III trial, we assessed patients' recurrence of breakthrough CINV after antiemetic prophylaxis for anthracycline+cyclophosphamide (AC) for breast cancer, comparing C1 short CINV vs. extended CINV as a secondary analysis. Complete response (CR) and CINV duration were primary and secondary endpoints, respectively. CR was considered prophylaxis success; lack of CR was considered treatment failure (TF). RESULTS: Among 402 female patients, 99 (24.6%) had TF in C1 (TF1). The remaining 303 patients (CR1) had ≥93% CR rates in each subsequent cycle, while the 99 patients with TF1 had TF rates of 49.8% for cycles 2-4 (P < .001). The 51 patients with extended TF (≥3 days) in C1 had recurrent TF in 73/105 later cycles (69.5%, P < .001), while the 48 patients with short TF (1-2 days) in C1 had recurrent TF in 33/108 later cycles (30.6%). The relative risk of recurrence after C1 extended TF was 2.28 (CI 1.67-3.11; P < .001) compared to short TF. CONCLUSIONS: Prophylaxis success in C1 led to >90% repeat success across cycles of AC-based chemotherapy. For patients with breakthrough CINV, extended duration strongly predicted recurrent CINV. The duration of CINV should be closely monitored, and augmenting antiemetic prophylaxis considered for future cycles when extended CINV occurs.

RESUMEN

Topical chlormethine yields high response rates in mycosis fungoides cutaneous T-cell lymphoma with early discontinuation often attributed to skin reactions. We evaluated over 4,000 patients and found an association of clinician case volume with treatment duration and early discontinuation of chlormethine gel. The minority of clinicians with high patient volume markedly outperformed clinicians with only few patients on both outcome parameters, yet case volume as low as five patients seemed to mark a threshold for avoiding early discontinuation of treatment regimen.

RESUMEN

Aim: In the absence of comparative studies, guidelines consider neurokinin 1 receptor antagonists (RAs) as interchangeable. We evaluated the pooled efficacy from three cisplatin registration trials, each with arms containing netupitant/palonosetron (NEPA), a fixed neurokinin 1 RA (netupitant)/serotonin Type 3 (5-HT3) RA (palonosetron) combination, and an aprepitant (APR) regimen. Materials & methods: Efficacy data were pooled for rates of complete response (CR: no emesis/no rescue medication), complete protection (CR + no significant nausea), total control (CR + no nausea) and no significant nausea during acute (0-24 h), delayed (>24-120 h) and overall (0-120 h) phases post chemotherapy. Results: Among 621 NEPA and 576 APR patients, response rates were similar for the acute phase, and generally favored NEPA during delayed and overall phases. CR rates for NEPA versus APR were 88.4 versus 89.2%, 81.8 versus 76.9% (p < 0.05) and 78.4 versus 75.0% during the acute, delayed and overall phases, respectively. Conclusion: Oral NEPA administered on day 1 was more effective than a 3-day APR regimen in preventing delayed nausea and vomiting associated with cisplatin.


Lay abstract Oral netupitant/palonosetron (NEPA) is an innovative product that combines two drugs (netupitant and palonosetron) in a single capsule to prevent nausea and vomiting associated with certain types of chemotherapy. In this paper we pooled together the results of three studies comparing the efficacy of NEPA to two drugs from the same classes administered separately (aprepitant regimen) in patients with various solid tumors receiving cisplatin, a type of chemotherapy with a high likelihood of causing nausea and vomiting. In summary, NEPA was more effective than the aprepitant regimen in preventing nausea and vomiting in the later days (days 3­5) following chemotherapy.

RESUMEN

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) contributes to avoidable acute care, a metric now tracked in Medicare's oncology outcome measure. CINV is preventable, yet guidelines are often not followed. We sought to quantify acute care involving CINV and other avoidable toxicities after highly emetogenic chemotherapy (HEC) to identify excess risk and assess clinician adherence to antiemesis guidelines for HEC. MATERIALS AND METHODS: We retrospectively evaluated U.S. electronic health records (2012-2018) using Medicare's OP-35 outcome measure to identify avoidable acute care involving any of 10 toxicities, including CINV, after HEC regimens relative to non-HEC. Antiemetic guideline adherence was defined as use ofneurokinin-1 (NKl) receptor antagonists Q5 (RAs) plus 5-hydroxytryptamine type 3 RA+ dexamethasone at HEC initiation. RESULTS: Among 17,609 patients receiving HEC, acute care rates associated with HEC chemotherapy included 32% cisplatin, 31% carboplatin, and 21% anthracycline/cyclosphospharnide (AC), with 76% meeting the criteria as avoidable events. Oxaliplatin rates were 29%. Avoidable acute care occurred 1.83 times (95% confidence interval, 1.76-1.91, p < .0001) as often after HEC versus non-HEC excluding oxaliplatin; CINV-related acute care occurred 2.29 times as often. Nonadherence to antiemesis guidelines occurred in 34% and 24% of cisplatin and AC courses, respectively, because of omission of a NKl RA. CONCLUSIONS: Patients treated with HEC regimens experienced high avoidable acute care use, 1.8 times the risk seen for other chemotherapy. Nonadherence to guideline-directed antiemetic prophylaxis highlights the need to ensure adherence to antiemetic guidelines, including the use of NKl RA in HEC. IMPLICATIONS FOR PRACTICE: After survival, perhaps the most important goal in oncology is limiting avoidable acute care, a goal now used by Medicare to impact cancer reimbursement. This study found that patients treated with highly emetogenic chemotherapy (HEC) regimens had high rates of avoidable acute care use, 1.8 times the risk seen for other chemotherapy. A substantial proportion of the avoidable acute care involved chemotherapy-induced nausea and vomiting. Results showed that incomplete adherence to national antiemetic guidelines for HEC regimens primarily driven by omission of upfront neurokinin-1 receptor antagonist use, suggesting that improved adherence can meaningfully resolve this gap in quality and cost of care.

RESUMEN

BACKGROUND: Clinician adherence to antiemetic guidelines for preventing chemotherapy-induced nausea and vomiting (CINV) caused by highly emetogenic chemotherapy (HEC) remains poorly characterized. The primary aim of this study was to evaluate individual clinician adherence to HEC antiemetic guidelines. PATIENTS AND METHODS: A retrospective analysis of patients receiving HEC was conducted using the IBM Watson Explorys Electronic Health Record Database (2012-2018). HEC antiemetic guideline adherence was defined as prescription of triple prophylaxis (neurokinin-1 receptor antagonist [NK1 RA], serotonin type-3 receptor antagonist, dexamethasone) at initiation of cisplatin or anthracycline + cyclophosphamide (AC). Clinicians who prescribed ≥5 HEC courses were included and individual guideline adherence was assessed, noting the number of prescribing clinicians with >90% adherence. RESULTS: A total of 217 clinicians were identified who prescribed 2,543 cisplatin and 1,490 AC courses. Patients (N=4,033) were primarily women (63.3%) and chemotherapy-naïve (92%) with a mean age of 58.6 years. Breast (36%) and thoracic (19%) cancers were the most common tumor types. Guideline adherence rates of >90% were achieved by 35% and 58% of clinicians using cisplatin or AC, respectively. Omission of an NK1 RA was the most common practice of nonadherence. Variation in prophylaxis guideline adherence was considerable for cisplatin (mean, 71%; SD, 29%; coefficient of variation [CV], 0.40) and AC (mean, 84%; SD, 26%; CV, 0.31). CONCLUSIONS: Findings showed substantial gaps in clinician adherence to HEC CINV guidelines, including a high variability across clinicians. Clinicians should review their individual clinical practices and ensure adherence to evidence-based CINV guidelines to optimize patient care.

RESUMEN

PURPOSE: To assess, from a United States (US) perspective, the cost-effectiveness of chemotherapy-induced nausea and vomiting (CINV) prophylaxis using a single dose of netupitant and palonosetron in a fixed combination (NEPA) versus aprepitant plus granisetron (APR + GRAN), each in combination with dexamethasone, in chemotherapy-naïve patients receiving highly emetogenic chemotherapy (HEC). METHODS: We analyzed patient-level outcomes over a 5-day post-HEC period from a randomized, double-blind, phase 3 clinical trial of NEPA (n = 412) versus APR + GRAN (n = 416). Costs and CINV-related utilities were assigned to each subject using published sources. Parameter uncertainty was addressed via multivariate probabilistic sensitivity analyses (PSA). RESULTS: Compared to APR + GRAN, NEPA resulted in a gain of 0.09 quality-adjusted life-days (QALDs) (4.04 vs 3.95; 95% CI -0.06 to 0.25) and a significant total per-patient cost reduction of $309 ($943 vs $1252; 95% CI $4-$626), due principally to $258 in lower medical costs of CINV-related events ($409 vs $668; 95% CI -$46 to $572) and $45 in lower study drug costs ($531 vs $577). In the PSA, NEPA resulted in lower costs and higher QALD in 86.5% of cases and cost ≤ $25,000 per quality-adjusted life-year gained in 97.8% of cases. CONCLUSIONS: This first-ever economic analysis using patient-level data from a phase 3 trial comparing neurokinin-1 receptor antagonist (NK1 RA) antiemetic regimens suggests that NEPA is highly cost-effective (and in fact cost-saving) versus an aprepitant-based regimen in post-HEC CINV prevention. Actual savings may be higher, as we focused only on the first chemotherapy cycle and omitted the impact of CINV-related chemotherapy discontinuation.

RESUMEN

PURPOSE: After ASCO and National Comprehensive Cancer Network guideline recommendations for triple antiemetic prophylaxis for carboplatin area under the curve (AUC) ≥ 4, and the publication of studies documenting avoidable acute care after chemotherapy involving nausea and vomiting (NV) and other toxicities, we studied clinician adherence to the guideline change and assessed avoidable acute-care use. METHODS: Using a large electronic health record database, we evaluated antiemetic prophylaxis as recommended in the guidelines and post-chemotherapy avoidable acute-care use (defined as involving any of NV or 8 other toxicities) for patients initiating carboplatin or other chemotherapy from October 2012 to August 2018. RESULTS: We identified 11,554 carboplatin courses. After the guideline change adding neurokinin-1 receptor antagonists (RAs) for carboplatin AUC ≥ 4, its use rose to 20% of courses from the prior average of 16%; virtually all courses also included a 5-HT3 RA plus dexamethasone. We found avoidable acute care in 23% of courses; one quarter of these events were associated with NV. Acute care rates after carboplatin mirrored those after other highly emetogenic chemotherapy or oxaliplatin and exceeded those after other chemotherapy regimens. The > 80% shortfall in adherence may have been caused by low awareness or acceptance of the guideline change and/or by poor awareness of avoidable acute-care use after carboplatin. CONCLUSION: Neurokinin-1 RA prophylaxis for carboplatin AUC ≥ 4 remains low and largely unchanged despite National Comprehensive Cancer Network and ASCO 2017 recommendations for inclusion. NV and avoidable acute care involving NV seen after carboplatin were consistent with other highly emetogenic chemotherapy. Clinician action is required to remediate incomplete prophylaxis and to no longer place patient outcomes, resources for cancer treatment, and clinician reimbursement at risk.

RESUMEN

Background: Chemotherapy-induced nausea and vomiting (CINV) are among the most common and debilitating side-effects patients experience during chemotherapy, and are associated with considerable acute care use and healthcare cost. It is estimated that 70-80% of CINV could be prevented through appropriate use of CINV prophylaxis; however, suboptimal CINV compliance and control remains an issue in clinical practice. Netupitant/palonosetron (NEPA) is a fixed combination of serotonin-3 (5-HT3) and neurokinin-1 (NK1) receptor antagonists (RAs), respectively, indicated for the prevention of acute and delayed nausea and vomiting associated with highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). Phase 3 clinical trials showed a significantly higher complete response rate in both acute and delayed CINV in chemotherapy-naïve patients receiving NEPA compared to patients receiving palonosetron. Objective: The objective of this study was to estimate the budgetary impact of adding NEPA to a US payer or practice formulary for CINV prophylaxis. Methods: A model was developed to estimate the impact of adding NEPA to the formulary of a hypothetical US payer with 1.15 million members, including 150,000 (13%) Medicare beneficiaries. The model compared the annual total costs of CINV-related events and CINV prophylaxis in two scenarios: base year (no NEPA) and comparator year (10% and 5% NEPA usage in HEC and MEC patients, respectively). A univariate sensitivity analysis was conducted to explore the effect of variability in model parameters on the budget impact. Results: A total of 2,021 patients were eligible to receive CINV prophylaxis. With NEPA, CINV prophylaxis costs increased by 0.7% ($3,493,630 vs $3,518,760) while medical costs associated with CINV events decreased by 3.9% ($15,118,639 vs $14,532,442), resulting in a net cost saving of $561,067 (3.0%) for the health plan ($18,612,269 vs $18,051,202), or $0.04 per member per month. This was equivalent to saving $5,011 per patient moved to NEPA. Among all 5-HT3 RA + NK1 RA regimens, NEPA was associated with the lowest CINV-related costs, leading to the lowest total cost of care. Conclusions: Adding NEPA to a payer or practice formulary results in a net decrease in the total budget due to a substantial reduction in CINV event-related resource utilization and medical costs, and an increase in pharmacy costs <1%, saving over $5,000 per patient.

RESUMEN

Dose reductions or interruptions may be required to manage treatment-associated adverse events among patients with myelodysplastic syndromes (MDS) treated with lenalidomide; such modifications are recommended to sustain therapy and maximize treatment duration. The aim of this retrospective case-control study was to determine the relationship between lenalidomide dose modification (DM), duration of lenalidomide therapy (DOT), and patient outcomes in patients with MDS. Those patients with database follow-up >20months (n=305) were more likely to have received erythropoiesis-stimulating agents (ESAs) (P=0.004), had longer median DOT (P<0.001), and higher rate of DM (P<0.001) versus those with shorter follow-up (n=306). Multivariate analysis indicated that lenalidomide DM (odds ratio [OR] 1.08) and prior ESA treatment (OR 2.40) were significantly associated with longer follow-up; transfusion dependence before lenalidomide initiation was associated with a significantly shorter follow-up (OR 0.60). These data suggest that effective management of lenalidomide treatment using dose reduction and/or delay is associated with longer DOT, which can improve patient outcomes.

RESUMEN

Myelodysplastic syndromes (MDS) are characterized by ineffective hematopoiesis resulting in refractory cytopenias. Red blood cell (RBC) transfusions can improve anemia; however, prolonged transfusion dependence (TD) is associated with increased morbidity and mortality. Disease-modifying therapy (DMT) for MDS can reduce transfusion requirements, although the optimum timing of DMT initiation is unclear. This retrospective study analyzed linked SEER registry and Medicare claims (2006-2012) to estimate the impact of DMT-initiation (azacitidine, decitabine, or lenalidomide) timing (≤ 3 vs.>3months from start of TD) on the likelihood of achieving transfusion independence (TI) among 508 TD patients with MDS. Mean time to DMT was 28days for early initiators (n=351) and 187days for late initiators (n=157). Fewer early initiators used erythropoiesis-stimulating agents before achieving TI versus late initiators (61.5% vs. 73.9%; P=0.007). In multivariate analyses, early DMT initiation predicted TI achievement (HR, 1.69; P<0.001); patients who met minimum active therapy-exposure requirements were more likely to achieve TI (HR, 2.12; P<0.001). Higher rates of TI were associated with reduced time between onset of TD and DMT initiation. Similarly, patients meeting the minimum treatment-exposure threshold had higher TI rates.

RESUMEN

Transfusion dependence (TD) among myelodysplastic syndromes (MDS) patients negatively impacts survival and health-related quality of life. We evaluated cost patterns of MDS care during TD and transfusion independence (TI). MDS patients were identified from a US claims database (2008-2013). TD was defined as ≥2 consecutive 8-week periods with ≥1 claim during each, and no interim 56-day period without transfusion; TI as 8 subsequent transfusion-free weeks; and transfusion frequency as the mean interval between transfusions during the TD period. 13,741 patients were included; 19% were TD and 70% had a mean interval between transfusions of ≤28 days. During a 2-year period, TD patients incurred a mean total cost of $17,815/patient-month; 53% higher for those with ≤28 days ($19,498) vs. >28 days ($12,717) between transfusions. Among patients who achieved TI, mean total cost was $7874/patient-month. For TD-MDS patients, cost increases are proportional to transfusion frequency and achieving TI yields economic benefits.

RESUMEN

OBJECTIVE: To assess the role of additional biopsies performed with loop electrosurgical excisional procedure (LEEP) in predicting the likelihood of persistent high grade intraepithelial neoplasia. METHODS: Clinicopathologic data were abstracted from women who underwent excision of high grade intraepithelial lesions between 2001 and 2014. Persistent disease was defined as uninterrupted high grade intraepithelial neoplasia, whereas recurrent disease was defined as disease diagnosed ≥1year after treatment with intervening normal evaluation. Chi-square and Fisher's exact tests were used to examine associations between demographic and histologic parameters and clinical outcomes. RESULTS: A total of 606 women underwent LEEP for high grade intraepithelial neoplasia (HSIL), of whom, 178 (29%) were additionally evaluated by endocervical curettage, 80 (13%), top hat and 99 (16%), both procedures. With mean follow-up of 1.9±1.5years, persistent disease was identified in 87 women (14%) while recurrent disease was diagnosed in 20 (3%). After adjusting for age, HIV status and histologic grade of disease, the presence of disease at the endocervical margin (aOR=2.2, 95% CL 1.8-5.5, p<0.0001), with endocervical curettage (aOR=2.39, 95% CL 1.2-9.9, p=0.025) or on top hat (aOR=4.0, 95% CL 1.1-16.2, p=0.04) correlated with the likelihood of persistent but not recurrent disease. Only endocervical margin status remained predictive (p=0.03) of outcome after controlling for pre-procedure likelihood of endocervical disease. Sensitivity of endocervical margin status for persistent disease was 56.9% with specificity of 72.2%. Positive predictive value (PPV) was 24.9% and negative predictive value (NPV) 90.9%. CONCLUSIONS: Despite frequent use of additional procedures to sample the endocervix, these strategies do not improve the ability of endocervical margin status to predict persistent or recurrent dysplasia.

RESUMEN

OBJECTIVE: To examine direct cost to patients associated with oral oncolytics for the management of multiple myeloma (MM) both before and after financial assistance, and assess the effect on adherence. METHODS: In this retrospective study, pharmacy claims were analyzed for those patients with a diagnosis of MM who received thalidomide, lenalidomide, or pomalidomide from a large specialty pharmacy in the US between January 1, 2011, and December 31, 2013. Average direct cost to patients, per prescription, was analyzed both before and after financial assistance. Adherence was assessed through an analysis of medication possession ratio (MPR) for those patients who filled a prescription ≥2 times throughout the 3-year time period. RESULTS: A total of 77,821 prescriptions for thalidomide, lenalidomide, and pomalidomide were filled by 6731 unique patients between January 1, 2011, and, December 31, 2013. The average direct cost to patients, per prescription, for any of these three agents was $227.23 prior to financial assistance and $80.11 after financial assistance, representing an average patient savings of $147.14 per prescription. Prior to financial assistance, the average direct cost to patients was ≤$50 for 57.6% of all prescriptions. After financial assistance, 86.2% of patients had a direct cost of ≤$50 per prescription. Adherence, as assessed by MPR, did not vary significantly based on direct cost to the patient. LIMITATIONS: This study included patients receiving therapy from a single specialty pharmacy for a single indication. There may be patients included in the analysis who received prescriptions from other pharmacies prior to or after the prescriptions available for analysis. Most of the prescriptions included in the analysis were for lenalidomide. CONCLUSIONS: This retrospective study demonstrated that the specialty pharmacy helped patients significantly reduce their direct cost expenditures by securing funding and co-pay assistance.

RESUMEN

BACKGROUND: Few studies have addressed the cost patterns of patients with multiple myeloma (MM) before and after first relapse. This US claims analysis evaluated, from a US health plan perspective, patterns of total direct costs of care from treatment initiation to progression for patients with MM treated with novel agents, using time to next therapy (TTNT) as a proxy measure for progression. METHODS: A retrospective study was conducted using a large US claims database, evaluating patients with claims for MM between 2006 and 2013. Patients with claims for stem cell transplant (SCT) were excluded. The analysis focused on patients receiving lenalidomide (LEN) or bortezomib (BORT) based treatment, for whom complete claim history was available through initiation of subsequent treatment. Average patient monthly direct costs were determined, including medical and pharmacy costs, and total cost patterns over quarterly time periods were calculated. RESULTS: The study population comprised 2843 patients with newly diagnosed MM (NDMM) and 1361 with relapsed MM. Total monthly cost for patients with NDMM declined steadily, from $15,734 initially to $5082 at 18+ months after therapy. Upon initiation of second-line therapy, total monthly costs rose to $13,876 and declined to $6446 18 months later. Although NDMM cost levels for individual ordinal months were similar between the LEN and BORT groups, TTNT was longer for LEN-based treatments (37 months). The BORT-treated cohort had higher average monthly total costs for NDMM and for the common time period through 37 months after initiation of therapy ($7534 vs $10,763 for LEN and BORT, respectively). Key limitations of this study, in addition to the lack of mortality and staging information available from claims data, include the definition of TTNT based on change in treatment or a defined gap in therapy prior to retreatment, which may differ from actual time of progression in some patients. CONCLUSIONS: For patients with NDMM receiving either LEN- or BORT-based treatment without SCT, followed until TTNT, total direct monthly costs (drug + medical) declined steadily over time. Monthly costs returned to near initial levels when patients began second-line therapy and then followed a similar pattern of decline. Due to the longer TTNT for patients initiated on LEN and the associated longer period of below-average costs, patients initiated with LEN-based treatments had mean monthly total costs >$3200 lower than total costs for patients initiated on BORT during the first 3 years after starting treatment, cumulating to nearly $120,000 in lower costs for patients initiated on LEN.

RESUMEN

OBJECTIVES: Advances in survival in multiple myeloma have focused payer attention on the cost of care. An assessment was conducted to compare the costs of two recent treatments for relapsed/refractory multiple myeloma (rrMM), from the perspective of a US payer. METHODS: An economic model estimated the total costs of care for two guideline-recommended therapies in rrMM patients: bortezomib (BORT) and lenalidomide plus dexamethasone (LEN/DEX). To evaluate total treatment costs, the costs associated with drug treatment, medical resource utilization, and adverse event (AE) management were determined for each regimen over a common 1-year period. Medical costs and grade 3/4 AE costs were based on rates from published literature, package inserts, and fee schedules (US dollars). To evaluate cost per outcome, assessments determined the monthly costs without disease progression based on pivotal clinical trials (APEX [BORT] and MM-009/MM-010 [LEN/DEX]). Univariate sensitivity analyses and alternative scenarios were also conducted. RESULTS: Drug costs for the treatments were very similar, differing by under $10 per day. Medical and AE management costs for BORT were higher by more than $40 per day. Treatment with BORT had annual excess total costs of >$17,000 compared with LEN/DEX. A cost advantage for LEN/DEX was maintained across a variety of sensitivity analyses. Total cost per month without progression was 11% lower with LEN/DEX. LIMITATIONS: This analysis relied on separate studies having similar comparators, populations, and end-points. Actual treatment patterns and costs pre- and post-relapse may vary from the base scenario and sensitivities modeled. The 12-month time frame captures the preponderance of costs for a relapse line of therapy, yet may not reflect the entirety of costs. There is insufficient evidence to determine whether, or how, a difference in the lifetime costs of the two regimens would vary from the 1-year cost difference. CONCLUSION: While rrMM treatment with BORT and LEN/DEX had comparable drug costs, total treatment costs for BORT were higher due to ongoing direct medical and AE management costs. Total costs per outcome (a month without disease progression) were lower for LEN/DEX.
