Identifying drivers of first-line HR+/HER2- metastatic breast cancer treatment choices.

Aim: Assess factors associated with first-line (1L) treatment for HR+/HER2- metastatic breast cancer. Materials & methods: A cross-sectional survey of 250 US oncologists was conducted. Correlations were calculated between treatment class and demographics, treatment perceptions and other clinical/nonclinical characteristics. Results: Efficacy and safety/tolerability were critical in oncologists' 1L decision-making. CDK4/6i use positively correlated with proportion of Medicare and postmenopausal patients (r = 0.54-0.67). Chemotherapy use demonstrated positive correlations with perimenopausal and premenopausal patients and symptom burden (r = 0.31-0.42). Aromatase inhibitor (AI) monotherapy correlated positively with anticipated treatment compliance (r = 0.42). Conclusion: Efficacy and safety/tolerability were most important to 1L decision-making. Clinical characteristics corresponded with CDK4/6i and chemotherapy use. Anticipated compliance was associated with AI monotherapy use.

Patients in the USA with a certain type of metastatic breast cancer (mBC, i.e., HR+/HER2−) might get chemotherapy or hormone therapy alone instead of new and potentially better medicines called cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) as their first treatment.Researchers wanted to understand how US cancer specialists decided the first treatment for this type of mBC. In a survey of 250 cancer specialists, researchers looked at different factors that might influence decision-making, including patient characteristics, doctors' opinions about the treatments and other medical and non-medical features. This study also examined the connections between these factors and the cancer specialists' choice of first treatment.Researchers found that cancer specialists care most about how well a treatment works and how safe it is when choosing the first treatment for HR+/HER2− mBC. They are more likely to use CDK4/6i if their patients have Medicare coverage or are older (i.e., women who have been through menopause). Chemotherapy is chosen if their patients are younger (i.e., women who are near and before menopause) or have more symptoms. Cancer specialists tend to choose first treatment with hormone therapy alone if they think their patients have a hard time following their treatment plan. The results showed that patient characteristics, doctors' opinions of treatments and other medical and non-medical factors play a role in choosing treatment for HR+/HER2− mBC. By understanding these factors, researchers can work toward improving treatment choices for patients with this type of mBC.

A latent class analysis of factors influencing preferences for infant respiratory syncytial virus (RSV) preventives among pregnant people in the United States.

A maternal vaccine and long-acting monoclonal antibody (mAb) were recently approved to protect infants against respiratory syncytial virus (RSV). We identified subgroups of pregnant people with different preferences for RSV preventives and respondent characteristics associated with subgroup membership. An online survey, including a discrete choice experiment (DCE), was conducted among US pregnant people. RSV preventive attributes included effectiveness, duration of protection during RSV season, injection recipient/timing, preventive type (vaccine or mAb), and type of visit required to receive injection. In DCE choice tasks, pregnant people selected between two hypothetical preventive profiles with varying attribute-levels and a no-preventive option. Logistic regression, including latent class analysis (LCA), was used to analyze the data. Of 992 pregnant people (mean age: 30.0 years), 60.3% were expecting their second/later birth. LCA identified three preference subgroups: 'Effectiveness' (preventive choice mostly driven by increases in effectiveness; 51.4% class membership probability), 'Season' (preventive choice mostly driven by improvement in duration of protection during the RSV season; 39.2% class membership probability), and 'No Preventive' (frequently chose no-preventive option; 9.4% class membership probability). 'Effectiveness' and 'Season' preferred maternal vaccine over mAb; mAb was preferred by 'No Preventive.' Perceiving RSV as serious for infants, higher health literacy, and lower household income were associated with 'Effectiveness.' Perceiving RSV as serious for pregnant people was associated with 'Season.' Perceiving RSV to not be serious for pregnant people and not being employed were associated with 'No Preventive.' Subgroups of pregnant people vary in preferences for RSV preventives. Most pregnant people preferred a maternal vaccine, although some may be more willing to accept alternative preventive options.

Healthcare Providers' and Pregnant People's Preferences for a Preventive to Protect Infants from Serious Illness Due to Respiratory Syncytial Virus.

We assessed the impact of respiratory syncytial virus (RSV) preventive characteristics on the intentions of pregnant people and healthcare providers (HCPs) to protect infants with a maternal vaccine or monoclonal antibodies (mAbs). Pregnant people and HCPs who treated pregnant people and/or infants were recruited via convenience sample from a general research panel to complete a cross-sectional, web-based survey, including a discrete choice experiment (DCE) wherein respondents chose between hypothetical RSV preventive profiles varying on five attributes (effectiveness, preventive type [maternal vaccine vs. mAb], injection recipient/timing, type of medical visit required to receive the injection, and duration of protection during RSV season) and a no-preventive option. A best-worst scaling (BWS) exercise was included to explore the impact of additional attributes on preventive preferences. Data were collected between October and November 2022. Attribute-level preference weights and relative importance (RI) were estimated. Overall, 992 pregnant people and 310 HCPs participated. A preventive (vs. none) was chosen 89.2% (pregnant people) and 96.0% (HCPs) of the time (DCE). Effectiveness was most important to preventive choice for pregnant people (RI = 48.0%) and HCPs (RI = 41.7%); all else equal, pregnant people (RI = 5.5%) and HCPs (RI = 7.2%) preferred the maternal vaccine over mAbs, although preventive type had limited influence on choice. Longer protection, protection starting at birth or the beginning of RSV season, and use for both pre-term and full-term babies were ranked highest in importance (BWS). Pregnant people and HCPs strongly preferred a preventive to protect infants against RSV (vs. none), underscoring the need to incorporate RSV preventives into routine care.

Exploring humanistic burden of fatigue in adults with multiple sclerosis: an analysis of US National Health and Wellness Survey data.

BACKGROUND: This retrospective study examined the humanistic burden of fatigue in patients with relapsing-remitting multiple sclerosis (RRMS), compared with adults without MS, using data from the 2017 and 2019 US National Health and Wellness Survey. METHODS: The 5-item Modified Fatigue Impact Scale (MFIS-5) was used to assess level of fatigue (MFIS-5 score <15: low fatigue [LF]; MFIS-5 score ≥15: high fatigue [HF]) in patients with RRMS. Health-related quality of life (HRQoL) measures (Short Form 36-Item Health Survey version 2, Euroqol-5 Dimensions-5 Levels [EQ-5D-5L], Patient Health Questionnaire-9 [PHQ-9], Generalized Anxiety Disorder-7 [GAD-7], Perceived Deficits Questionnaire-5) and treatment-related characteristics were assessed. RESULTS: In total, 498 respondents were identified as RRMS (n=375 RRMS+LF, n=123 RRMS+HF) and compared with 1,494 matched non-MS controls. RRMS+LF and RRMS+HF had significantly lower Short Form 6 Dimensions health utility, Mental and Physical Component Summary, and EQ-5D-5L scores and higher PHQ-9 and GAD-7 scores, compared with matched non-MS controls (all p<0.001); scores were worse for RRMS+HF than RRMS+LF across all measures (all p<0.001). A higher proportion of RRMS+HF reported moderate-to-severe depression and moderate-to-severe anxiety, compared with RRMS+LF and matched non-MS controls (both p<0.001). Fatigue was a significant predictor of poor HRQoL across all measures (all p<0.001). CONCLUSIONS: Patients with RRMS experienced lower HRQoL with higher levels of fatigue, highlighting an unmet need. Results may help to inform physician-patient communication and shared decision-making to address fatigue and its associated impact on patients' HRQoL.

Patient experience and unmet needs in high-risk nonmuscle-invasive bladder cancer: Insights from qualitative interviews and a cross-sectional survey.

OBJECTIVES: To evaluate patient experience, unmet needs, and burden among patients with high-risk nonmuscle-invasive bladder cancer (HR-NMIBC) treated with Bacillus Calmette-Guérin (BCG). METHODS: This cross-sectional study included HR-NMIBC patients who received BCG treatment in the past 3 years. The study, preceded by a focused literature review, was conducted in 2 phases: 1) qualitative interviews with 32 patients in the United States (US), France, Germany, and United Kingdom (UK) and 2) quantitative survey of 150 patients in the US. Both phases of the study assessed patient characteristics, treatment history, experience, and perceptions, as well as side effects, pain, discomfort, and time burden associated with BCG treatment. The quantitative survey included additional items related to BCG treatment satisfaction, health-related quality of life (HRQoL), productivity, and healthcare resource utilization. Descriptive statistics and bivariate subgroup comparisons were reported. RESULTS: All patients in both study phases received transurethral resection of the bladder tumor (TURBT). Nearly all patients reported keeping their bladder/avoiding radical cystectomy (RC) was important (99%). Results from the quantitative survey reported a substantial impact to cancer-specific HRQoL of patients, with lower mean scores on physical (64.7), social (62.8), and role functioning (56.7) as measured by the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-30). Most patients (69%) were satisfied overall with BCG treatment, although satisfaction declined with increased number of side effects, higher numbers of BCG administrations, and greater discomfort (all P < 0.05). CONCLUSIONS: Most HR-NMIBC patients were satisfied overall with BCG treatment. Approximately half of the patients had stopped BCG treatment, notably, most during the induction phase, suggesting nonadherence to guidelines which recommend maintenance treatment after induction. Future treatments should focus on delaying or avoiding recurrence and cystectomy while reducing patient discomfort and discontinuation prior to completing the recommended course of treatment.

Psychosocial Wellbeing among Patients with Breast Cancer during COVID-19.

The impact of coronavirus disease 2019 (COVID-19) on the wellbeing of breast cancer (BC) patients is not well understood. This study described psychosocial problems among these patients in the United States (US) during the COVID-19 pandemic. Data were collected from BC patients via an online self-report survey between 30 March-6 July 2021 to assess the prevalence of COVID-19 diagnosis history and potential depression, health-related quality of life, COVID-related stress, and financial toxicity. Patients with early-stage (eBC) and metastatic (mBC) disease were compared. Of 669 patients included in the analysis, the prevalence of COVID-19 diagnosis history (10.9% versus 7.7%) and potential depression (33.7% versus 28.3%) were higher in mBC than eBC patients. Patients with eBC (versus mBC) had higher scores on nearly all Functional Assessment of Cancer Therapy-Breast scales (all, p < 0.001). For the Psychological Impact of Cancer subscales measuring negative coping strategies, the emotional distress score was the highest (9.1 ± 1.8) in the overall sample. Comprehensive Score for Financial Toxicity scores were higher in eBC than in mBC patients (24.2 ± 11.3 vs. 21.3 ± 10.2, p < 0.001). Overall, the COVID-19-related stress score was highest for danger/contamination fears (8.2 ± 5.6). In conclusion, impairments to psychosocial wellbeing among patients during the pandemic were observed, particularly financial toxicity and poor mental health and emotional functioning, with greater problems among mBC patients.

The association between social determinants of health and patient-centred outcomes in adults with heart failure with reduced ejection fraction.

AIMS: To explore the associations between social determinants of health and patient-centred outcomes among adults with chronic heart failure with reduced ejection fraction. DESIGN: Cross-sectional online self-report survey. METHODS: A survey assessing social determinants of health (demographics, socio-economic position, affordability of care and social support) and patient-centred outcomes, including the Kansas City Cardiomyopathy Questionnaire-12 and validated measures of medication adherence, treatment satisfaction, treatment burden and mental health, was completed by 512 adults with chronic heart failure with a reduced ejection fraction between 06 March and 29 June 2020. Multivariable analyses included linear and logistic regression. RESULTS: Female gender, having a care partner, and being offered financial assistance with medications were associated with worse health status, while perceiving medication as affordable and being married were associated with better health status. Females and having Medicaid, dual Medicaid/Medicare or no medical insurance were associated with a higher likelihood of depression, and non-white race/ethnicity was associated with less depression. Medication adherence was lower in patients having a care partner and offered financial assistance. Patients being offered financial and medication management assistance were more likely to be overwhelmed by the treatment burden, whereas those having some college education were less so. CONCLUSIONS: Social determinants of health are associated with patients' disease-specific health status, mental health and treatment satisfaction and burden. These findings underscore the importance of assessing social determinants of health in clinical practice and the need for developing and testing novel strategies to determine whether they improve patients' health. IMPACT: The relationship between social determinants of health- and patient-centred outcomes was assessed; affordability of care and social support factors were most strongly associated with outcomes for patients with chronic heart failure and reduced ejection fraction, underscoring the importance of assessing social determinants of health in routine clinical care. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Social determinants of health data could potentially inform care delivery for patients with heart failure and reduced ejection fraction by helping to identify those who require additional support to manage their symptoms, access care and adhere to treatment. Social support and affordability of treatment were associated with most patient-centred outcomes, suggesting these factors may provide clinicians with an indicator of a patient's level of general well-being that could be assessed during routine follow-up care. REPORTING METHOD: This research followed the STROBE checklist for cross-sectional studies. PATIENT OR PUBLIC CONTRIBUTION: Adults who have heart failure with reduced ejection fraction that consented to participate in the study provided the data used for all analyses reported on in the manuscript. Service users, caregivers or members of the public had no involvement in the study.

Evaluation of under-testing and under-diagnosis of tick-borne encephalitis in Germany.

BACKGROUND: Tick-borne encephalitis (TBE), a viral infectious disease affecting the central nervous system, potentially resulting in prolonged neurological symptoms and other long-term sequelae. Case identification can be challenging as TBE can be associated with non-specific symptoms, and even in cases consistent with typical TBE symptoms, the rate of laboratory testing to confirm cases is unknown. This study assessed real-world TBE laboratory testing rates across Germany. METHODS: In this retrospective cross-sectional study, physicians provided data on TBE decision-making, laboratory testing (serological), and diagnostics behavior via in-depth qualitative interviews (N = 12) or a web-based quantitative survey of their patient medical records (N = 166). Hospital-based physicians who specialized in infectious disease, intensive care unit, emergency room, neurology, or pediatrics with experience managing and ordering testing for patients with meningitis, encephalitis, or non-specific central nervous system symptoms in the past 12 months were included. Data were summarized via descriptive statistics. TBE testing and positivity rates were assessed for the aggregate sample of 1400 patient charts and reported by presenting symptoms, region, and tick bite exposure. RESULTS: TBE testing rates ranged from 54.0% (non-specific neurological symptoms only) to 65.6% (encephalitis symptoms only); the percentage of TBE positive results ranged from 5.3% (non-specific neurological symptoms only) to 36.9% (meningitis symptoms only). TBE testing rates were higher among those with a tick bite history and/or who presented with headache, high fever, or flu-like symptoms. CONCLUSIONS: The findings of this study suggest that patients with typical TBE symptoms are likely under-tested, thus likely leading to under-diagnosis in Germany. To ensure appropriate case identification, TBE testing should be consistently integrated into routine practice for all patients who present with relevant symptoms or exposure to common risk factors.

Relationships between headache frequency, disability, and disability-related unemployment among adults with migraine.

BACKGROUND: Migraine is the second most common cause of disability worldwide. Understanding the relationship between migraine and employment status is critical for policymakers, as disability-related unemployment is associated with eligibility for private or governmental disability insurance payments and other associated support for those unable to work because of disability. OBJECTIVE: To assess the association between migraine frequency and selfreported employment status and overall disability in a US representative survey. METHODS: Using data from the 2019 National Health and Wellness Survey (NHWS) (Kantar Health), adults in the United States (aged 18-65 years) reporting at least 1 migraine day in the past 30 days were categorized by headache frequency: low-frequency episodic migraine (LFEM) (≤4 days/month), moderate-frequency EM (MFEM) (5-9 days/month), high-frequency EM (HFEM) (10-14 days/month), or chronic migraine (CM) (≥15 days/month). A control group of adults without migraine with similar baseline characteristics was identified by propensity score matching. Disability-related unemployment was defined as participants responding "short-term disability" or "long-term disability" to occupational status on the NHWS. The frequency of short- or long-term disability was then evaluated across headache frequency groups. In addition, participants were asked to assess migraine-related disability via the Migraine Disability questionnaire (MIDAS). RESULTS: A total of 1,962 respondents with LFEM, 987 with MFEM, 554 with HFEM, and 926 with CM were included in this analysis, along with 4,429 matched controls. Headache frequency was associated both with increased MIDAS score and with employment disability (P < 0.001); 12.3% (n = 114 of 926) of participants with CM reported employment disability, as did 4.4% (n = 86 of 1,962) of the LFEM group and 6.9% (n = 306 of 4,429) of matched controls. There was considerable discordance between the proportion of participants classified as disabled via MIDAS vs those reporting employment-related disability. CONCLUSIONS: More frequent migraine headaches are associated with a higher likelihood of self-reported short- and long-term employment disability and overall migraine-related disability, suggesting that health and economic policymakers must seek ways to maximize the employment opportunities for people living with migraine that may benefit from novel preventive treatments.

Financial Toxicity among Patients with Breast Cancer during the COVID-19 Pandemic in the United States.

This study reported the prevalence of financial distress (financial toxicity (FT)) and COVID-19-related economic stress in patients with breast cancer (BC). Patients with BC were recruited from the Ciitizen platform, Breastcancer.org, and patient advocacy groups between 30 March and 6 July 2021. FT was assessed with the COmprehensive Score for financial Toxicity (COST) instrument. COVID-19-related economic stress was assessed with the COVID-19 Stress Scale. Among the 669 patients, the mean age was 51.6 years; 9.4% reported a COVID-19 diagnosis. The prevalence rates of mild and moderate/severe FT were 36.8% and 22.4%, respectively. FT was more prevalent in patients with metastatic versus early BC (p < 0.001). The factors associated with FT included income ≤ USD 49,999 (adjusted odds ratio (adj OR) 6.271, p < 0.0001) and USD 50,000-USD 149,999 (adj OR 2.722, p < 0.0001); aged <50 years (adj OR 3.061, p = 0.0012) and 50-64 years (adj OR 3.444, p = 0.0002); living alone (adj OR 1.603, p = 0.0476); and greater depression severity (adj OR 1.155, p < 0.0001). Black patients (adj OR 2.165, p = 0.0133), patients with income ≤ USD 49,999 (adj OR 1.921, p = 0.0432), or greater depression severity (adj OR 1.090, p < 0.0001) were more likely to experience COVID-19-related economic stress. FT was common in patients with BC, particularly metastatic disease, during COVID-19. Multiple factors, especially lower income and greater depression severity were associated with financial difficulties during COVID-19.

Assessment of economic burden of fatigue in adults with multiple sclerosis: An analysis of US National Health and Wellness Survey data.

BACKGROUND: Fatigue, a common disabling symptom in multiple sclerosis (MS), is reported by the majority of patients. However, evidence on the economic burden of fatigue in MS by fatigue status is limited. This study aimed to evaluate the economic burden of fatigue, including healthcare resource utilization (HCRU), labor force participation, and Work Productivity and Activity Impairment (WPAI), among adults with relapsing-remitting MS (RRMS) by low fatigue (LF) vs high fatigue (HF) and compared with adults without MS. METHODS: This cross-sectional, retrospective, observational study included pooled data from the 2017 and 2019 US National Health and Wellness Survey. The RRMS sample included respondents aged ≥18 years who reported being diagnosed with MS by a healthcare provider (HCP) and reported having RRMS. Non-MS controls included respondents aged ≥18 years who did not report being diagnosed with MS by an HCP. Fatigue was measured using the Modified Fatigue Impact Scale-5 (MFIS-5). Outcomes included HCRU (HCP visits, emergency department visits, and hospitalizations in the past 12 months), labor force participation (yes vs no), WPAI (absenteeism, presenteeism, total work productivity impairment, and activity impairment), and annualized costs (direct medical, indirect, and total). Respondents with RRMS were propensity-score matched to non-MS controls (ratio 1:3). RRMS respondents were categorized as having LF (MFIS-5<15; RRMS+LF) and HF (MFIS-5≥15; RRMS+HF). Bivariate analysis compared matched non-MS controls, RRMS+LF, and RRMS+HF. Multivariable analyses were conducted among RRMS to evaluate associations between fatigue (continuous variable) and outcomes. RESULTS: Overall, 498 respondents with RRMS (RRMS+LF, n=375; RRMS+HF, n=123) and 1494 matched non-MS controls were included. RRMS+HF and RRMS+LF had more HCRU in the past 12 months than non-MS controls, whereas RRMS+HF had greater HCRU than RRMS+LF (all p<0.05). WPAI was also higher among RRMS+HF and RRMS+LF, compared with non-MS controls, as well as higher in RRMS+HF vs RRMS+LF (all p<0.001). RRMS+HF had significantly higher annualized direct medical costs than RRMS+LF and matched non-MS controls ($19,978 vs $10,656, p=0.007; vs $8,048, p<0.001). Among employed respondents, RRMS+HF and RRMS+LF had higher annualized indirect costs than non-MS controls, with RRMS+HF also having higher annualized indirect costs than RRMS+LF ($23,647 vs $13,738 vs $8,001; all p<0.01); total annualized costs were higher in RRMS+HF and RRMS+LF, compared with non-MS controls, as well as RRMS+HF vs RRMS+LF (all p<0.01). In multivariable models, fatigue was significantly and positively associated with the number of HCP visits in the past 12 months (p=0.002); not participating in the labor force (p<0.001); and absenteeism, presenteeism, total work productivity impairment, and activity impairment (all p<0.001). CONCLUSION: RRMS poses a substantial economic burden on patients and society, and this burden is disproportionately associated with HF.

Real-world usage of bevacizumab-bvzr biosimilar in US oncology practice.

OBJECTIVES: Bevacizumab is commonly used to treat solid tumors. However, little is known about the manner and the extent to which bevacizumab biosimilars are utilized in real-world oncology practice in the United States. The objective of this study was to describe patient and provider characteristics and treatment patterns associated with the recently introduced bevacizumab-bvzr biosimilar. STUDY DESIGN: Retrospective cohort study. METHODS: A retrospective analysis of medical and pharmacy claims between January 24, 2019, and July 31, 2020, was performed. Adult patients with at least 1 claim indicating usage of bevacizumab-bvzr were included. Patients who could not be assigned to an applicable diagnosis group were excluded. Index treatment date was defined as the date of the first claim for bevacizumab-bvzr. Descriptive analysis was conducted for all study variables. RESULTS: A total of 206 patients were included; patients most often were 65 years or older (49.5%), were female (62.6%), and resided in the West (45.1%). The most common indications observed for bevacizumab-bvzr were metastatic colorectal cancer (mCRC; 51.0%), cancer of the female genital organs (CFGO; 27.2%), glioblastoma (11.2%), and non-small cell lung cancer (8.7%). Overall, 72.4% and 48.2% of patients with mCRC and CFGO, respectively, had switched to bevacizumab-bvzr from the reference drug or another bevacizumab biosimilar. Bevacizumab-bvzr was used in chemotherapy combination regimens for patients with mCRC and CFGO. CONCLUSIONS: Utilization was observed in extrapolated indications. Findings suggest that both switching between reference product and bevacizumab biosimilars and using bevacizumab-bvzr as part of chemotherapy combination regimens have been adopted in US oncology practice.

Understanding treatment patterns and patient-reported outcomes associated with the use of authorized generics and corresponding independent generics across multiple therapeutic areas.

OBJECTIVES: To assess patient characteristics, treatment patterns, and patient-reported outcomes (PROs) associated with authorized generics (AGs) and independent generics (IGs) use. METHODS: Prescription claims and National Health and Wellness Survey (NHWS) data were linked. Adults with billable national drug code (AG or IG), NHWS completion from June 2015 to July 2019, AG or IG on-hand at NHWS completion, and continuous insurance eligibility in 12 months pre- and post-NHWS completion were included. To be included, all unique medication formulations had to have at least one AG and one IG observation. PRO index date was NHWS completion; claims index date was defined as the first prescription claim identified during the 180-day period prior to NHWS completion for the same active ingredient and formulation type that was on-hand at NHWS completion. RESULTS: Patients (N = 20,229; 17.2% AG users) in six therapeutic areas (attention deficit-hyperactivity disorder [ADHD], antidepressants, beta blockers [BBs], calcium channel blockers [CCBs], statins, and thyroid) were included. Generally, AG (vs. IG) users were younger and differed in regional access and insurance type (all, p < .05). In multivariable analysis, significant differences were observed for presenteeism and overall work impairment (BBs), healthcare provider visits (BBs), and indirect costs (thyroid) (all, p < .05). AG and IG users differed in persistence (ADHD and statins; both, p < .05) and switch (BBs and CCBs; both, p < .01) rates. CONCLUSIONS: PRO differences were often small in magnitude and varied by therapeutic area. The impact of switching should consider observed PRO differences, patient preferences, and market availability of AG and IG alternatives.

Benefit-risk trade-offs in treatment choice in advanced HER2 negative breast cancer: patient and oncologist perspectives.

Aim: To evaluate which treatment attributes US patients and oncologists prioritize in HER2 negative advanced breast cancer (ABC). Methods: Preferences were assessed via a discrete choice experiment. Also, treatment goal statements were rated on an agreement scale. Results: Patients (n = 169) most valued improving overall survival (OS), followed by improving nausea and neuropathy. Oncologists (n = 117) most valued improving OS, followed by neuropathy and progression-free survival. Regarding treatment goals, oncologists (67%) perceived that patients are more focused on efficacy than quality of life; fewer patients (29%) agreed with this statement; 81% of oncologists and 51% of patients agreed that patients prefer oral treatment. Conclusion: Patients and oncologists were willing to accept increases in toxicities in exchange for efficacy improvements in HER2 negative ABC.

The goal of this study was to understand the preferences of patients and physicians for the benefits and risks associated with the treatment of advanced breast cancer that expresses normal amounts of the HER2 protein (termed as HER2 negative). Respondents completed an exercise where they compared two treatment options at a time that varied in their level of effectiveness and their potential for certain side effects and then selected the treatment option they most preferred. From this exercise, the treatment features that matter the most to patients and physicians were discovered. The most important treatment features for patients were lengthening life expectancy, decreasing the chance of experiencing nausea affecting appetite, and decreasing the chance of experiencing nerve damage involving numbness and/or pain, possibly severe, in hands and feet which may limit daily activities. The most important treatment features for physicians were lengthening life expectancy, decreasing the change of experiencing nerve damage involving numbness and/or pain, possibly severe, in hands and feet which may limit daily activities, and lengthening the time that cancer remains stable and does not worsen. Patients and physicians also rated how much they agreed with statements about their goals for treatment. While 67% of oncologists believed that their patients are more focused on killing the cancer than their quality of life, only 27% of patients were more focused on killing the cancer than their quality of life.

Patient and Caregiver Preferences for First-Line Treatments of Metastatic Non-Small Cell Lung Cancer: A Discrete Choice Experiment.

PURPOSE: The approval of immune checkpoint inhibitors for metastatic non-small-cell lung carcinomas (mNSCLC) treatment has presented more care options. Therefore, it is important to identify the benefit-risk trade-offs patients and caregivers are willing to make among potential treatment options. This study quantified the preferences of patients and caregivers for attributes of mNSCLC treatment. METHODS: Patients with mNSCLC and caregivers completed an online survey assessing preferences using a discrete choice experiment. Respondents chose between hypothetical treatment profiles, with varying levels for 7 attributes associated with first-line treatment, including overall survival (OS), progression-free survival, select adverse events (AEs), and regimen (caregivers). Hierarchical Bayesian modeling was used to estimate attribute-level preference weights. RESULTS: Patients (n = 308) and caregivers (n = 166) most valued increasing OS from 11 to 30 months, followed by decreasing the risk of a serious AE (grade 3/4) that may lead to hospitalization from 70% to 18%. These attributes were over twice as important to both sets of respondents as the other attributes measured. Patients and caregivers would accept increases in the risks of a serious AE (grade 3/4) from 18% to 70% and all grades nausea from 10% to 69% if OS increased by 16.8 and 4.0 months, respectively. The least valued attributes were all grades of pneumonitis (patients) and all grades of skin rash (caregivers). CONCLUSION: Patients and caregivers are willing to make trade-offs between efficacy and toxicity and may require up to 1.5 years of increased OS to accept a higher risk of AEs. These results can provide guidance to oncologists when engaging in shared-decision making discussions.

The Association of Oral Stimulant Medication Adherence with Work Productivity among Adults with ADHD.

OBJECTIVE: Examine associations between oral psychostimulant pharmacotherapy adherence, work productivity, and related indirect costs among US adults with ADHD. METHODS: Medication adherence (Medication Adherence Reasons Scale [MAR-Scale]), work productivity and activity impairment (Work Productivity and Activity Impairment-General Health questionnaire), and ADHD symptom level (Adult ADHD Self-Report Scale version 1.1 Symptom Checklist) were assessed in this noninterventional online survey of adults who self-reported having an ADHD diagnosis and were currently receiving oral psychostimulant treatment for ≥3 months. RESULTS: Of 602 respondents, 395 had low/medium adherence (LMA: MAR-Scale total score ≥1) and 207 had high adherence (HA: MAR-Scale total score 0). After adjusting for covariates, the LMA group had significantly greater levels of absenteeism, absenteeism-related indirect costs, and total indirect costs (all p < .01) than the HA group. CONCLUSION: In adults with ADHD using oral psychostimulants, lower medication adherence was associated with greater absenteeism and indirect costs.

Evolving Perceptions, Utilization, and Real-World Implementation Experiences of Oncology Monoclonal Antibody Biosimilars in the USA: Perspectives from Both Payers and Physicians.

BACKGROUND: The adoption of oncology biosimilars has been slow in the USA, which may be attributed in part to stakeholder perceptions and lack of operational guidance that supports favorable access to biosimilars. OBJECTIVE: Our objective was to understand the real-world implementation experiences with oncology biosimilars of US payers and healthcare professionals (HCPs) as their experience with biosimilars has evolved. METHODS: In-depth qualitative interviews with payers (n = 20) and HCPs (n = 17 physicians, n = 3 practice managers) were conducted. Payers included managed care organizations (MCOs), integrated delivery networks, and pharmacy benefit managers (PBMs). Physicians were affiliated with a healthcare network or were community based, specialized in hematology/oncology, and had prescribed oncology biosimilars. Audio transcripts of the interviews were coded using MaxQDA software to enable descriptive analysis of the qualitative data. RESULTS: Over 80.0% of physicians perceived the efficacy and safety of biosimilars to be highly comparable to that of originators. Up to 87.5% of physicians reported using biosimilars in > 50% of their treatment-naïve patients and were comfortable using biosimilars in all approved indications. To encourage utilization, 75.0% of MCOs/PBMs preferred biosimilars over originators in treatment-naïve patients and implementation via step therapy. Physician involvement in choosing biosimilars was minimal, which was largely dependent on practice protocols or insurance preferences. The major factor influencing payers' coverage decisions and biosimilar adoption was potential cost savings. CONCLUSIONS: US payers and physicians who have experience with biosimilars have favorable views of oncology biosimilars, particularly for treatment-naïve patients. A framework for integrating biosimilars into oncology practice is developing, primarily driven by insurance coverage, contracting, and cost benefits.

Patients' and oncologists' preferences for second-line maintenance PARP inhibitor therapy in epithelial ovarian cancer.

Aim: To understand the preferences of US patients and oncologists for PARP inhibitors as second-line maintenance (2LM) for epithelial ovarian cancer. Methods: A discrete choice experiment was conducted to assess the preferences of treatment attributes. Results: The most valued attributes were risk of grade 3/4 adverse events (AEs; patients, n = 204) and progression-free survival (PFS; oncologists, n = 151). To accept a 37% increased risk of grade 3/4 AEs, PFS would need to increase by 27.9 months (patients) and 6.3 months (oncologists). The least valued attributes were dosing form/frequency (patients) and grade 3/4 anemia risk (oncologists). Conclusion: Patients' and oncologists' willingness to make benefit-risk trade-offs in the 2LM setting suggests that the PFS gains observed in selected studies of poly (ADP-ribose) polymerase inhibitors in BRCA-mutated disease are worth the toxicity risk.

Plain language summary Maintenance therapy is a treatment option intended to keep ovarian cancer from coming back or getting worse for as long as possible after responding to chemotherapy. PARP inhibitors are a new type of maintenance therapy for ovarian cancer. This study aimed to understand the patients' and physicians' preferences for the benefits and risks associated with different PARP inhibitors used as maintenance therapy for ovarian cancer. Participants were asked to compare various treatment options based on their different safety profiles, effectiveness and form of medication (e.g., three capsules by mouth once a day versus two tablets by mouth twice a day), and then choose the treatment they most preferred. Through this exercise, the treatment features that mattered most to patients and physicians were identified. The most important treatment feature for patients was decreasing the chance of experiencing a serious side effect that requires medical intervention or hospitalization. In contrast, physicians valued lengthening the time that a cancer remains stable and does not worsen. To accept a 37% higher chance of experiencing a side effect that requires medical intervention or hospitalization, patients expect their cancer to remain stable and not worsen for an additional 28 months. This was a large difference from the 6 months that the physicians would consider as acceptable. The least important treatment features for patients are the amount of pills required per dose, the form of the given medication (e.g., tablet vs capsule) and the schedule of taking the treatment. On the other hand, physicians were least concerned about lowering the risk of experiencing low blood counts that, requiring medical intervention.

Patient-centered Outcomes in HFrEF Following a Worsening Heart Failure Event: A Survey Analysis.

BACKGROUND: Heart failure is a chronic disease punctuated by intermittent exacerbations that require hospitalization or intravenous diuretic therapy. The association of worsening heart failure events (WHFEs) with patient-centered outcomes in heart failure with reduced ejection fraction (HFrEF) remains unexplored. METHODS AND RESULTS: Patients with HFrEF completed an online survey assessing health status, medication adherence, treatment satisfaction, treatment burden, and medication costs and affordability. Patients with and without WHFEs were compared on all study variables, with adjustment for patient characteristics using linear or logistic regression. Overall, 512 patients (52.0% WHFEs) were included. Patients with WHFEs more commonly had depression (55.3% vs 24.0%), anxiety (46.2% vs 17.9%), and insomnia (77.8% vs 44.7%; P < 0.001 for all). Patients with WHFEs had lower adjusted mean Kansas City Cardiomyopathy Questionnaire values (52.9 vs 56.0) and Satisfaction with Medications Questionnaire values (70.5 vs 72.6) and higher Treatment Burden Questionnaire scores (51.1 vs 45.1; P < 0.001). Medication-related beliefs and long-term concerns were independently associated with nonadherence in patients with WHFE (adjusted odds ratios: 4.2 and 5.2, respectively; P < 0.01 for both). Patients with WHFE incurred 50.0% higher median monthly out-of-pocket HF prescription medication costs and less often perceived HF medications to be affordable. CONCLUSIONS: WHFE is associated with several adverse impacts on patients with HFrEF. Additional support is warranted to manage symptoms, comorbidities, and HF treatments to improve adherence and outcomes.

Real-world use and acceptance of biosimilar monoclonal antibodies of rituximab in oncology practice in the USA.

Aim: To describe treatment patterns and patient and provider characteristics associated with the recently introduced biosimilar rituximab-pvvr. Methods: This retrospective analysis included adult patients with one or more claims for rituximab-pvvr, with an index date of 23 January 2020 and a study period covering 1 January 2019-31 July 2020. Results: Of 249 patients included, the most common rituximab-pvvr indications were non-Hodgkin's lymphoma (77.5%) and chronic lymphocytic leukemia (11.2%). Some patients with non-Hodgkin's lymphoma (42.5%) and chronic lymphocytic leukemia (39.3%) switched to rituximab-pvvr from the reference product or another rituximab biosimilar. Most patients were aged ≥65 years (63.5%) and were male (54.6%). Most (59.0%) rituximab-pvvr prescribers practiced in the south of the USA. Conclusion: Utilization occurred in approved and extrapolated indications. These preliminary findings suggest switching between reference product and rituximab biosimilars; rituximab-pvvr combination regimens are being adopted in real-world oncology practice.

Lay abstract A biosimilar is a biological medication that is highly similar in structure and function to a biological medication already approved by the US FDA ­ the 'original biologic'. The first biosimilars approved to treat certain blood cancers have become available in the USA. This study examined how a recently introduced rituximab biosimilar was being utilized, looking at patient and physician characteristics from a medical and prescription insurance claims database. This study did not examine the safety or effectiveness of this medication. While initial data are limited, the biosimilar, rituximab-pvvr, appears to be utilized to treat the same types of cancer as the original biologic, rituximab. The biosimilar was most frequently prescribed for non-Hodgkin's lymphoma and chronic lymphocytic leukemia.
