Real-World Usage and Clinical Outcomes of Alectinib Among Post-Crizotinib Progression Anaplastic Lymphoma Kinase Positive Non-Small-Cell Lung Cancer Patients in the USA

Background: Alectinib is an approved treatment for anaplastic lymphoma kinase (ALK)-positive patients with advanced non-small-cell lung cancer. Despite positive supporting clinical data, there is a lack of real-world information on the usage and patient outcomes of those treated with alectinib post-crizotinib progression. Methods: Participating oncologists (N=95) in the USA were recruited from an online physician panel to participate in a retrospective patient chart review. Physicians randomly selected eligible patients (ie, patients who progressed on crizotinib as their first ALK inhibitor and were treated with alectinib as their second ALK inhibitor), collected demographics and clinical history from their medical charts, and entered the data into an online data collection form. Results: A total of N=207 patient charts were included (age: 60.1±10.4 years; 53.6% male). The patients in our sample were older (median age of 60 vs 53 years), were more likely to be current smokers (12% vs 1%), had better performance status (45% vs 33% had an Eastern Cooperative Oncology Group [ECOG] of 0), and were less likely to have an adenocarcinoma histology (83% vs 96%) relative to published clinical trials. The objective response rate was higher than in clinical trials (67.1% vs 51.3%, respectively) as was the disease control rate (89.9% vs 78.8%, respectively), though it varied by race/ethnicity, ECOG, and prior treatment history. Discontinuation (0.0%) and dose reductions (3.4%) due to adverse events were uncommon in alectinib. Conclusion: Patients using alectinib post-crizotinib in clinical practice are older, more racially/ethnically and histologically diverse than patients in published trials. Real-world response rates were high and similar to those reported in clinical studies, though there is some variation by patient characteristics. Alectinib was well tolerated in clinical practice as reflected by the rates of discontinuation, dose reductions, and dose interruptions

Burden of peripheral arterial disease in Europe and the United States: a patient survey

Abstract Background The aim of the current study was to quantify the burden of peripheral arterial disease (PAD) with respect to health-related quality of life, work productivity and activity impairment, and healthcare resource utilization. Methods Data were obtained from the 2010 EU National Health and Wellness Survey (NHWS), which included participants from France, Germany, Italy, Spain, and the UK (5EU, N = 57,805) as well as the 2010 US NHWS (N = 75,000). The NHWS is an annual, cross-sectional, self-administered Internet survey which employs a stratified random sampling frame to match the age and gender characteristics of the NHWS sample with known population statistics. Participants who self-reported a diagnosis of PAD were compared with participants who did not self-report a diagnosis of PAD on health-related quality of life (mental and physical component summary scores and health utilities from the Short Form-12v2), work productivity and activity impairment (Work Productivity and Activity Impairment questionnaire), and healthcare resource use in terms of the number of physician visits, emergency room visits, and hospitalizations in the past six months through regression modeling adjusting for demographics and health characteristics. Results A total of 743 (1.29%) and 777 (1.04%) participants self-reported a diagnosis of PAD in the 5EU and US, respectively. After adjusting for demographics and health characteristics, patients with PAD reported worse health-related quality of life, as measured by health utilities (5EU: 0.66 vs. 0.70; US: 0.66 vs. 0.72; all p &lt; .05), greater overall work impairment percentage (5EU: 38.27% vs. 27.48%; US: 23.89% vs. 14.26%) and greater healthcare resource use compared to participants without PAD (all p &lt; .05). Conclusions These results suggest a significant burden for patients with PAD in both the 5 EU countries and the US with respect to both quality of life and economic outcomes. Improved management of these patients may have profound effects from both patient and societal perspectives. </jats:sec

Impact of self-rated osteoarthritis severity in an employed population: Cross-sectional analysis of data from the national health and wellness survey

<p>Abstract</p> <p>Background</p> <p>Although osteoarthritis (OA) often affects older persons, it has a profound effect on individuals actively employed. Despite reports of reduced productivity among workers with OA, data are limited regarding the impact of OA among workers. The objective of this study was to evaluate the impact of self-rated OA severity on quality of life, healthcare resource utilization, productivity and costs in an employed population relative to employed individuals without OA.</p> <p>Methods</p> <p>This cross-sectional analysis used data derived from the 2009 National Health and Wellness Survey (NHWS). Multivariable analyses characterized outcomes and costs (direct medical costs and indirect) among workers (full-time, part-time, or self-employed) ≥ 20 years of age who were diagnosed with OA and who self-rated their OA severity as mild, moderate, or severe relative to workers without OA. Evaluated outcomes included productivity, assessed using the Work Productivity and Impairment (WPAI) scale; health-related quality of life, using the SF-12v2 Health Survey; and healthcare resource utilization.</p> <p>Results</p> <p>4,876 workers reported being diagnosed with OA (45.0% mild, 45.9% moderate, and 9.1% severe); 34,896 workers comprised the non-OA comparator cohort. There was a greater proportion of females in the OA cohort (55.5% vs 45.6%; <it>P </it>< 0.0001) and more individuals in the 40-64 year and ≥ 65 year age ranges (<it>P </it>< 0.0001). As OA severity increased, workers reported more frequent pain, poorer quality of life, greater use of specific healthcare resources (hospitalizations) and reduced productivity. All outcomes indicated a significantly greater burden among workers with OA relative to those without OA (<it>P </it>< 0.0001). Estimated total annual costs per worker were $9,801 for mild OA,$14,761 for moderate OA, $22,111 for severe OA compared with$7,901 for workers without OA (<it>P </it>< 0.0001).</p> <p>Conclusions</p> <p>Workers with OA were characterized by significant disease and economic burdens relative to workers without OA that substantially increased with greater self-rated OA severity. Greater levels of OA severity were associated with reductions in quality of life and productivity, and increases in healthcare resource utilization and costs.</p

A cross-sectional assessment of the burden of COPD symptoms in the US and Europe using the National Health and Wellness Survey

INTRODUCTION: Past research has suggested significant relationships between symptoms and health outcomes among patients with COPD. However, these studies have generally focused on a broad COPD sample and may have included those not receiving proper treatment. As a result, the aim of this study was to document the burden of COPD symptoms among those who are currently treated with the standard-of-care (SOC) medications in both the US and Western Europe. METHODS: Data from the 2013 US (N=75,000) and 2011 (N=57,512)/2013 (N=62,000) European (France, Germany, Italy, Spain, and UK; 5EU) National Health and Wellness Survey (NHWS) were used. The NHWS is a health survey administered to a demographically representative sample of the adult population in each country. A total of 1,666 and 2,006 patients with self-reported physician diagnosis of COPD in the 5EU and US, respectively, were being treated with the appropriate SOC (based on self-reported medication use) and were included in the analyses. Symptoms (eg, dyspnea, coughing, wheezing) were reported descriptively and summed to create a symptom score (with higher score indicating more frequent symptoms). The relationships between the symptom score and patient outcomes (eg, health status using the Short Form-36 version 2 [SF-36v2], work productivity and activity impairment [WPAI], and self-reported health care resource use) were explored using regression modeling. RESULTS: Nearly all patients (99.7% and 99.8% in the 5EU and US, respectively) reported experiencing symptoms and >80% reported experiencing at least one symptom “often”. Increasing symptom scores were associated with poorer health status (unstandardized beta [b] =−0.87 and −0.78 for mental component summary and physical component summary, respectively, in the US and b =−0.67 and −0.79 in the 5EU, respectively; all P<0.05). Increasing symptom scores were also associated with greater work impairment (b =0.09 and 0.06 for the US and 5EU, respectively), activity impairment (b =0.05 and 0.06, respectively), and health care resource utilization (eg, hospitalizations: b =0.05 and 0.06, respectively) (all P<0.05). Approximately 70% of patients reported some level of non-adherence. Greater non-adherence was significantly associated with more frequent symptoms, poorer health status, and greater work impairment and health care resource use (all P<0.05). CONCLUSION: Patients with COPD who are using the appropriate SOC still experience symptoms, which have a significant effect on both humanistic and economic outcomes

The association between lower back pain and health status, work productivity, and health care resource use in Japan

INTRODUCTION: This study investigated the effect of pain severity on health status, work productivity, health care resource use, and costs among respondents with lower back pain (LBP), in Japan. MATERIALS AND METHODS: Data from the 2013 Japan National Health and Wellness Survey, a survey of Japanese adults, were analyzed (N=30,000). All respondents provided informed consent, and the protocol was institutional review board-approved. Respondents who reported experiencing LBP were propensity score–matched to those without LBP, based on demographics and health history. Using regression modeling, patients with mild, moderate, and severe pain were compared against matched controls, with respect to health status (Mental and Physical Component Summary scores, and health utilities from the Short Form(®)-36 Health Survey version 2), work productivity (Work Productivity and Activity Impairment – General Health version), health care resource use, and annual per-patient costs (estimated using published annual wages and resource use event costs). RESULTS: A total 1,897 patients reported experiencing LBP in the past month (6.32%); 52.45% reported their pain as mild, 32.79% as moderate, and 14.76% as severe. Increasing pain severity was associated with significantly lower levels of mental component scores (46.99 [mild], 42.93 [moderate], and 40.58 [severe] vs 48.10 [matched controls]), physical component scores (50.29 [mild], 46.74 [moderate], and 43.94 [severe] vs 52.93 [matched controls]), and health utilities (0.72 [mild], 0.66 [moderate], and 0.62 [severe] vs 0.76 [matched controls]) (all P<0.05). Indirect costs were significantly higher (P<0.05) among those with moderate (¥1.69 million [MM] [equivalent to $17,000, based on United States dollar exchange rates on September 1, 2014]) and severe (¥1.88 MM [$19,000]) pain, relative to matched controls (¥0.95 MM [$9,500]). Direct costs were only marginally different (P=0.05) between those with severe pain and matched controls (¥1.33 MM [$13,000] vs ¥0.54 MM [$5,000]). CONCLUSION: Increasing pain severity among respondents with LBP was associated with significantly worse health status, to a clinically-relevant degree, along with greater indirect and direct costs, in Japan

The association of sleep difficulties with health-related quality of life among patients with fibromyalgia

Abstract Background Difficulty sleeping is common among patients with fibromyalgia (FM); however, its impact on health-related quality of life (HRQoL) is not well understood. The aim of the current study was to assess the burden of sleep difficulty symptoms on HRQoL among patients with FM. Methods The current study included data from the 2009 National Health and Wellness Survey (N=75,000), which is a cross-sectional, Internet-based survey representative of the adult US population. The prevalence of sleep difficulty symptoms among patients with FM (n=2,196) were compared with matched controls (n=2,194), identified using propensity-score matching. Additionally, the relationship between the number of sleep difficulty symptoms (none, one, or two or more) and HRQoL (using the SF-12v2) was assessed using regression modeling, controlling for demographic and health history variables. Results Of the 2,196 patients with FM, 11.2% reported no sleep difficulty symptoms, 25.7% reported one sleep difficulty symptom, and 63.05% reported two or more sleep difficulty symptoms. The prevalence of sleep difficulty symptoms was significantly higher than matched controls. Patients with one and two sleep difficulty symptoms both reported significantly worse HRQoL summary and domain scores relative to those with no sleep difficulty symptoms (all p&lt;.05). Further, the relationship between sleep difficulty symptoms and HRQoL was significantly different between those with FM than matched controls, suggesting a uniqueness of the burden of sleep difficulties within the FM population. Conclusions Among the FM population, sleep difficulty symptoms were independently associated with clinically-meaningful decrements in mental and physical HRQoL. These results suggest that greater emphasis in the treatment of sleep difficulty symptoms among the FM population may be warranted. </jats:sec

Elranatamab efficacy in MagnetisMM-3 compared with real-world control arms in triple-class refractory multiple myeloma

Elranatamab efficacy in the single-arm, registrational MagnetisMM-3 trial (NCT04649359) was compared with that of physician's choice of treatment (PCT) for triple-class refractory multiple myeloma. MagnestisMM-3 eligibility criteria were applied to two USA-based oncology electronic health record databases, COTA and Flatiron Health (FH), to identify cohorts for this study (NCT05932290). Applied statistical techniques accounted for cohort imbalances. MagnetisMM-3 (BCMA-naive; n = 123) outcomes were compared with those from COTA (n = 239) and FH (n = 152). Elranatamab was associated with a significantly higher objective response rate (risk ratios, 1.88–2.25), significantly longer progression-free survival (hazard ratios [HRs], 0.37–0.57), and, across most analyses, significantly longer overall survival (HRs, 0.46–0.66) versus PCT. BCMA-naive patients who were treated with elranatamab exhibited significantly better outcomes than patients treated in real-world clinical practice.</p
