ABSTRACT

BACKGROUND: As new migraine therapies emerge, it is crucial for measures to capture the complexities of health-related quality of life (HRQoL) improvement beyond improvements in monthly migraine day (MMD) reduction. Investigations into the correlations between MMD reduction, symptom management, and HRQoL are lacking, particularly those that focus on improvements in canonical symptoms and improvement in patient-identified most-bothersome symptoms (PI-MBS), in patients treated with eptinezumab. This exploratory analysis identified efficacy measures mediating the effect of eptinezumab on HRQoL improvements in patients with migraine. METHODS: Data from the DELIVER study of patients with 2-4 prior preventive migraine treatment failures (NCT04418765) were inputted to two structural equation models describing sources of HRQoL improvement via Migraine-Specific Quality-of-Life Questionnaire (MSQ) scores. A single latent variable was defined to represent HRQoL and describe the sources of HRQoL in DELIVER. One model included all migraine symptoms while the second model included the PI-MBS as the only migraine symptom. Mediating variables capturing different aspects of efficacy included MMDs, other canonical symptoms, and PI-MBS. RESULTS: In the first model, reductions in MMDs and other canonical symptoms accounted for 35% (standardized effect size [SES] - 0.11) and 25% (SES - 0.08) of HRQoL improvement, respectively, with 41% (SES - 0.13) of improvement comprising "direct treatment effect," i.e., unexplained by mediators. In the second model, substantial HRQoL improvement with eptinezumab (86%; SES - 0.26) is due to MMD reduction (17%; SES - 0.05) and change in PI-MBS (69%; SES - 0.21). CONCLUSIONS: Improvements in HRQoL experienced by patients treated with eptinezumab can be substantially explained by its effect on migraine frequency and PI-MBS. Therefore, in addition to MMD reduction, healthcare providers should discuss PI-MBS improvements, since this may impact HRQoL. Health technology policymakers should consider implications of these findings in economic evaluation, as they point to alternative measurement of quality-adjusted life years to capture fully treatment benefits in cost-utility analyses.

ABSTRACT

BACKGROUND: To date, real-world evidence on persistence to anti-calcitonin gene-related peptide (anti-CGRP) monoclonal antibodies (mAbs) or onabotulinumtoxinA have excluded eptinezumab. This retrospective cohort study was performed to compare treatment persistency among patients with migraine on anti-CGRP mAbs (erenumab, fremanezumab, galcanezumab, or eptinezumab) or onabotulinumtoxinA. METHODS: This retrospective study used IQVIA PharmMetrics data. Adult patients with migraine treated with an anti-CGRP mAb or onabotulinumtoxinA who had 12 months of continuous insurance enrollment before starting treatment were included. A "most recent treatment episode" analysis was used in which the most recent episode was defined as the latest treatment period with the same drug (anti-CGRP mAb or onabotulinumtoxinA) without a ≥ 15-day gap in medication supply on/after June 25, 2020, to December 31, 2021. Patients were indexed at the start of their most recent episode. Patients were considered non-persistent and discontinued the therapy associated with their most recent episode if there was ≥ 15-day gap in medication supply. A Cox proportional-hazards model estimated the discontinuation hazard between treatments. The gap periods and cohort definition were varied in sensitivity analyses. RESULTS: The study included 66,576 patients (median age 46 years, 88.6% female). More eptinezumab-treated patients had chronic migraine (727/1074), ≥ 3 previous acute (323/1074) or preventive (333/1074) therapies, and more prior treatment episodes (3) than other treatment groups. Based on a 15-day treatment gap, patients on subcutaneous anti-CGRP mAbs had a 32% (95% CI: 1.19, 1.49; erenumab), 42% (95% CI: 1.27, 1.61; galcanezumab), and 58% (95% CI: 1.42, 1.80; fremanezumab) higher discontinuation hazard than those receiving eptinezumab, with this relationship attenuated, but still statistically significant based on 30-day and 60-day treatment gaps. There was no significant difference in the discontinuation hazard between eptinezumab and onabotulinumtoxinA. Based on a 15-day treatment gap among patients who newly initiated therapy, the discontinuation hazard of subcutaneous anti-CGRP mAbs remained significantly higher compared to eptinezumab and onabotulinumtoxinA. CONCLUSION: Patients treated with eptinezumab demonstrated persistency that was higher than subcutaneous anti-CGRP mAbs and similar to onabotulinumtoxinA.

ABSTRACT

BACKGROUND: This post hoc analysis aimed to estimate eptinezumab's therapeutic effect on health utilities and determined to which extent monthly migraine days (MMDs) explain changes in health utilities. RESEARCH DESIGN/METHODS: DELIVER, a randomized, double-blind, placebo-controlled phase 3b trial (NCT04418765), investigated eptinezumab efficacy and safety in patients with 2-4 prior migraine treatment failures. Regression analysis explored the relationship between utility scores and MMDs, with eptinezumab treatment as a covariate along with MMDs to identify any MMD-independent effect on utilities. Path analysis quantified eptinezumab's impact as mediated through MMD reduction. RESULTS: The base case model showed that each reduction in MMD was associated with a mean utility score increase (0.0189; 95% CI: 0.0180, 0.0198; P < 0.001). Mean utility score was generally higher for eptinezumab versus placebo, justifying addition of treatment effect to the base case model. Patients administered eptinezumab had on average 0.0562 (95% CI: 0.0382, 0.0742; P < 0.001) higher utility versus placebo when controlling for number of MMDs. From path analysis, MMD reduction resulting from eptinezumab treatment accounted for 53% additional utility gain observed in patients. CONCLUSIONS: Changes in MMDs alone inadequately captured migraine's impact on patient utility, as there was also a positive eptinezumab-driven, treatment-specific impact on utility score. TRIAL REGISTRATION: The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT04418765).

ABSTRACT

OBJECTIVE: To assess preferences among adults with migraine for differentiating attributes of injected or infused preventive treatment options and evaluate their importance in determining a treatment choice. BACKGROUND: Adults with migraine and health-care providers consider many factors when making treatment decisions. Injected or infused preventive migraine treatment options differ in several attributes, including mode of administration and dosing frequency, which may be preferentially selected or avoided by patients. Understanding a patient's preference is important for clinicians as they advise on various treatment options. METHODS: A total of 604 US adults diagnosed with migraine participated in an online survey that captured information on demographics, migraine history, and treatment preferences. A discrete choice experiment (DCE) was used to evaluate participants' preferences for specific attributes of injected/infused preventive migraine therapies. The DCE data were utilized to estimate attribute importance (expressed as a percentage) and identify subgroups that had different distributions of preferences. RESULTS: In the overall migraine population, mode of administration (28.8%), durability of effectiveness (27.0%), and speed of onset (25.5%) had the highest relative importance, whereas administration setting (9.9%) and dosing frequency (8.8%) had the lowest. Four distinct subgroups were identified: Group 1 (n = 128) preferred self-injection administration and durability of effectiveness; Group 2 (n = 189) expressed aversion to cranial injections; Group 3 (n = 158) prioritized rapid speed of onset; and Group 4 (n = 129) favored health-care provider administration and durability of effectiveness. CONCLUSIONS: Speed of onset, durability of effectiveness, and mode of administration are key moderators of treatment preference among US adults with migraine. Certain segments of the migraine population prioritize specific treatment attributes over others, with intravenous infusion not considered a barrier in three of four identified segments. Clinicians can best help their patients find the right medication if they understand which medication attributes are most and least important to them.

ABSTRACT

PURPOSE: Treatment of chronic myelogenous leukemia (CML) with tyrosine kinase inhibitors (TKIs) has improved survival but is associated with significant financial burden. We measured the annual trend in TKI utilization, Medicare gross payment, and patient out-of-pocket (OOP) expenditure from 2007 to 2016. METHODS: We used SEER linked to Medicare part-D claims data to identify prevalent CML cases from 2007 to 2016. TKI utilization was measured as the proportion of cases with at least one TKI fill in each year. Average TKI gross payment and median per-member per-month OOP expenditure were calculated from claims data and plotted annually from 2007 to 2016. Year-to-year percent change in gross payment and OOP expenditure was compared with inflation indices. RESULTS: The cohort included 3,189 CML cases with at least one TKI claim. The proportion of prevalent patients with a TKI fill in a year increased from 17.9% in 2007 to 52.8% in 2015. The average annual gross payment per 30-day supply of a TKI increased by an average of 12.8% throughout the period from $9,000 to $10,000 US dollars in 2016. There was no increasing trend in median OOP expenditure per 30-day supply, which varied between $450 and $600 US dollars. CONCLUSION: Rising TKI use and TKI drug prices place considerable financial pressure on Medicare part-D insurers. Although there was no increasing trend in OOP expenditure, it may be burdensome for Medicare patients who are likely retired on a fixed income. Our findings support legislation that mitigates increasing drug prices to protect the Medicare system and its beneficiaries.

ABSTRACT

PURPOSE OF STUDY: To estimate time allocation and labor cost for care coordinators (CCs), community health workers (CHWs), and mental health workers (MHWs) to conduct care coordination tasks in a pediatric care coordination program. PRIMARY PRACTICE SETTING: A public tertiary academic medical center in Chicago, IL. METHODOLOGY AND SAMPLE: A work-sampling study was conducted using a text message-based survey on 5 CCs, 20 CHWs, and 4 MHWs who volunteered to participate. Workers were randomly sampled within working hours to collect information on who was the subject of interaction and what service was being delivered over a 6-month period. Time allocation of workers to different subjects and services was summarized using descriptive statistics. RESULTS: Care coordinators allocated 41% of their time to managing CHW teams. Community health workers allocated 37% of time providing services directly to children and 26% to the parent/caregiver. Mental health workers allocated 16% of time providing services to children and 29% to the parent/caregiver. The care coordination program serviced 5,965 patients, with a total annual labor cost of $1,455,353. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Community health workers spent the majority of time working with patients and their families to conduct assessments. Mental health workers primarily addressed children's needs through their caregivers. Care coordinators primarily supported CHWs in coordinating care. Results may be used to inform development of such programs by determining services most often utilized, and labor cost may be used to inform program implementation and reimbursement.

ABSTRACT

PURPOSE: Patient-reported outcomes such as self-reported health (SRH) are important in understanding quality cancer care, yet little is known about links between SRH and outcomes in older patients with multiple myeloma (MM). We evaluated associations between SRH and mortality among older patients with MM. METHODS: We analyzed a retrospective cohort of patients ages ≥ 65 years diagnosed with first primary MM using the Surveillance, Epidemiology, and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) data resource. Pre-diagnosis SRH was grouped as high (excellent/very good/good) or low (fair/poor). We used Cox proportional hazards models to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for associations between SRH and all-cause and MM-specific mortality. RESULTS: Of 521 MM patients with mean (SD) age at diagnosis of 76.8 (6.1) years, 32% reported low SRH. In multivariable analyses, low SRH was suggestive of modest increased risks of all-cause mortality (HR 1.32, 95% CI 1.02-1.71) and MM-specific mortality (HR 1.22, 95% CI 0.87-1.70) compared to high SRH. CONCLUSION: Findings suggest that low pre-diagnosis SRH is highly prevalent among older patients with MM and is associated with modestly increased all-cause mortality. Additional research is needed to address quality of life and modifiable factors that may accompany poor SRH in older patients with MM.

ABSTRACT

PURPOSE: To examine the impact of pre-diagnosis depressive symptoms and mental health-related quality of life (HRQOL) on survival among older patients with multiple myeloma (MM). METHODS: We performed a retrospective cohort study using the Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey data resource. Patients aged 65 years and older diagnosed with first primary MM between 1998 and 2014 were identified, and presence of depressive symptoms was determined based on responses to 3 depression screening questions prior to MM diagnosis. Veterans RAND 12 mental component summary (MCS) scores were analyzed to evaluate mental HRQOL. We used multivariable Cox proportional hazards models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for risks of all-cause and cancer-specific mortality. RESULTS: Of 522 patients, mean (SD) age at diagnosis was 76.9 (6.1) years and 158 (30%) reported depressive symptoms. Patients with depressive symptoms had a higher number of comorbid conditions and nearly all (84%) scored below the median MCS. Pre-diagnosis depressive symptoms were not associated with all-cause (HR = 1.01, 95% CI 0.79-1.29) or cancer-specific mortality (HR = 0.94, 95% CI 0.69-1.28). MM patients scoring in the second MCS tertile (vs the highest tertile) had a modestly increased risk of all-cause (HR = 1.19, 95% CI 0.91-1.55) and cancer-specific mortality (HR = 1.17, 95% CI 0.86-1.60), but these estimates were not statistically significant. CONCLUSION: Pre-diagnosis depressive symptoms and lower mental HRQoL did not impact survival among older MM patients. Highly prevalent depressive symptoms among older MM patients deserve clinical attention. Such efforts can inform clinicians in tailoring care for this vulnerable population.
