Treatment Patterns and Health Resource Utilization in Patients With HR+/ HER2- Locally Advanced or Metastatic Breast Cancer in a Real-World Setting in Taiwan.

OBJECTIVES: This study aimed to understand current treatment patterns and healthcare resource utilization (HRU) of women with locally advanced or metastatic breast cancer (advanced breast cancer [ABC]) in Taiwan overall and within the subgroup of patients who were postmenopausal women with no previous systemic therapy in the ABC setting. METHODS: A chart review of anonymized data on patient characteristics, treatment patterns, and HRU was conducted via an online physician survey including 118 patient charts from women ≥ 18 years old with hormone receptor positive/human epidermal growth receptor negative ABC, diagnosed between 2015 and 2017. RESULTS: The mean age of all patients was 56.6 years (range 29-83). Among the 118 patients, the most common first-line systemic therapy group after diagnosis of ABC was endocrine-based therapy (39.0%) or endocrine therapy (ET) plus chemotherapy (ChT) combinations (38.1%). In the postmenopausal subgroup (n = 56), ET-based therapy was the most common (44.6%). Oncologist visits, at annual rate of 9.20 (95% confidence interval 8.81-9.60), and hospitalizations, at annual rate of 1.08 (95% confidence interval 0.96-1.22), were key drivers of HRU. Of the 118 patients, the 72 with at least one ChT agent in their first-line regimen had an annual hospitalization rate of 1.4 versus 0.45 admissions compared with the 46 patients on first-line ET-based therapy. CONCLUSIONS: Current treatment patterns suggest an unmet need for new medications that lead to reduction in high rate of ChT use. Results can inform future evaluations of new ABC treatments that estimate the health economic impact of their adoption in Taiwan.

Treatment Patterns, Clinical Outcomes and Health Care Resource Utilisation in Patients with EGFR-mutated Metastatic Non-Small Cell Lung Cancer: A Real-World Study in South Korea.

BACKGROUND: Despite the dynamic treatment landscape for EGFR mutant-positive metastatic non-small cell lung cancer (EGFRm+ mNSCLC), most of the earlier studies have focused on US or Western populations. OBJECTIVE: The objective of this study was to explore real-world treatment patterns and outcomes of South Korean patients with EGFRm+ mNSCLC. METHODS: Retrospective chart review of adult patients with EGFRm+ mNSCLC who received systemic treatment between January-2019 and June-2019. RESULTS: A total of 162 patients were included from 21 hospitals, with a median follow-up of 15.6 months. Median age was 65.0 years, 22% had central nervous system metastasis, and 57% and 38% had exon 19 deletion and exon 21 L858R, respectively. Among 144 patients (89%) who received first-line EGFR-tyrosine kinase inhibitor, afatinib was most the common (44%), followed by gefitinib (28%) and erlotinib (13%). First-line chemotherapy was more common when an EGFR-mutation was detected after versus before first-line treatment initiation (31% vs 5%). Discontinuation of first-line treatment was mostly due to disease-progression (81%) and toxicity (7%). Among 58 (78%) patients who received second-line treatment, osimertinib was the most common (40%). Most (60%) patients reported ≥1 Grade ≥3 adverse event during first-line treatment. Following initiation of first-line treatment, physician visits and chest X-rays were the most frequent healthcare utilisation events. Rates of emergency-room visits and hospitalization were 12% and 16%, respectively, with a mean length-of-stay of 10.4 days. At 12 months, overall survival rate was 95%, and numerically worse for patients with exon 21 versus 19 mutations. CONCLUSIONS: Characteristics and clinical outcomes of Korean patients with EGFRm+ mNSCLC in real-world practice were comparable to those observed in clinical trials. As osimertinib was not reimbursed for first-line treatment before study completion, further investigation is warranted to explore evolving treatment practice.

Real world evidence study on treatment patterns and health resource utilization in patients with HR+/HER2- locally advanced or metastatic breast cancer in Korea.

Objective: To understand current treatment patterns and health care resource utilization (HRU) of women with locally advanced or metastatic breast cancer (advanced breast cancer; ABC) in Korea overall and within patients who had progressed with prior endocrine therapy (as first-line treatment for metastatic disease) and patients with no prior systemic treatment (for advanced disease). Methods: A chart review was conducted in 109 patients (women ≥ 18 years old with HR+/HER2- ABC diagnosed between 2015 and 2017) from 11 hospitals. Anonymized data on patient characteristics, treatment patterns and HRU was abstracted. Results: Mean (range) age of all patients was 57.5 (40-81) years. Overall, the most common first-, second- and third-line systemic therapy after diagnosis of ABC were letrozole ± palbociclib (51%), endocrine therapy (ET)±everolimus (42%) or chemotherapy (ChT) (39%), and ChT (68%), respectively. In patients progressed with ET (n = 33) and those with no prior systemic treatment (n = 52), the most common first-line treatments were letrozole (82%) and letrozole + palbociclib (42%), respectively. The percentage of patients with at least one grade 3 or higher adverse event during first-line therapy was 93.1% vs 39.2% in patients on a ChT based regimen (N = 29) vs. ET (N = 74). Overall, oncologist visits, at an annual rate of 9.27 (95% CI: 8.87, 9.69) visits per month, and hospitalizations, with an annual rate of 0.44 (95% CI: 0.36, 0.54), and mean (SD) length of stay of 14.3 (10.32) days, were the key drivers of HRU. Conclusions: These findings on real world HRU reflected clinical guidelines and severity of ABC. Results can inform future evaluations of new ABC treatments that estimate the health economic impact of their adoption in Korea.

Treatment Patterns and Health Resource Utilization in Patients With Hepatocellular Carcinoma After Failure of Sorafenib in Real-World Setting in Taiwan.

OBJECTIVES: This study aimed to characterize current treatment patterns and healthcare resource utilization (HRU) observed among patients with hepatocellular carcinoma (HCC) after the failure of sorafenib in real-world setting in Taiwan. METHODS: A chart review was conducted in 130 patients; the inclusion criteria were patients with HCC who were aged 20 years or older and had received systemic therapy or best supportive care after failure of first-line systemic treatment with sorafenib between 2016 and 2018. Anonymized data on patient characteristics, treatment pathways, and survival were abstracted. RESULTS: The mean age of patients was 61.7 years (range 27-84); of these 130 patients, 103 (79%) were male, 81 (62%) had high alpha-fetoprotein (AFP) levels (≥400 ng/mL), and 96 (78.0%) were deceased at the time of data abstraction. After sorafenib therapy, 60 patients (46%) received systemic therapy, including nivolumab monotherapy (42%) and chemotherapy (25%). Oncologist visits at a semiannual per-patient rate of 3.7 (95% confidence interval [CI] 3.4-4.0) and hospitalizations at rate of 1.1 (95% CI 1.0-1.3) were the key contributors to HRU. Semiannual per-patient hospitalization rate was 1.3 (95% CI 1.1-1.5) in the high-AFP group. Median survival from discontinuation of sorafenib was 6.9 months (95% CI 5.9-9.0). CONCLUSIONS: This real-world evidence research on treatment patterns reflected substantial HRU consistent with the severity of HCC, particularly in the high-AFP group. Findings highlighted continuing high mortality in HCC, underlying a need for new treatments that can lengthen survival. Results can inform future evaluations of new HCC treatments that estimate the health economic impact of their adoption in Taiwan.

The impact of COVID-19 on antipsychotic prescriptions for patients with schizophrenia in Australia.

OBJECTIVE: To assess the impact, in the Australian setting, of the COVID-19 lockdown on antipsychotic supplies for patients with schizophrenia following a prescription from a new medical consultation when compared to the same periods in the previous 4 years. A secondary objective was to assess the volume of all antipsychotic supplies, from new and repeat prescriptions, over these same periods. METHODS: A retrospective pharmaceutical claims database study was undertaken, using the Department of Human Services Pharmaceutical Benefits Scheme 10% sample. The study population included all adult patients with three or more supplies of oral or long-acting injectable antipsychotics for the treatment of schizophrenia at any time between 1 June 2015 and 31 May 2020. The primary outcome compared volumes of dispensed antipsychotics from new prescriptions (which require a medical consultation) between 1 April and 31 May each year from 2016 to 2020. This was to analyse the period during which the Australian Government imposed a lockdown due to COVID-19 (April to May 2020) when compared the same periods in previous years. RESULTS: There was a small (5.7%) reduction in the number of antipsychotics dispensed from new prescriptions requiring a consultation, from 15,244 to 14,372, between April and May 2019 and the same period in 2020, respectively. However, this reduction was not statistically significant (p = 0.75) after adjusting for treatment class, age, gender, location and provider type. CONCLUSION: The COVID-19 restrictions during April and May 2020 had no significant impact on the volume of antipsychotics dispensed from new prescriptions for patients with schizophrenia when compared to the volume of antipsychotics dispensed from new prescriptions during the same period in previous years.

Antipsychotic utilisation and persistence in Australia: A nationwide 5-year study.

OBJECTIVES: To evaluate the utilisation and persistence of antipsychotics for the treatment of schizophrenia in Australia. METHODS: A retrospective study using the Australian Pharmaceutical Benefits Scheme database of a representative 10% sample. All adults with schizophrenia who were dispensed three or more supplies of oral (including clozapine) or long-acting injectable antipsychotics between 1 June 2015 and 31 May 2020 were included. Persistence time in treatment was evaluated using survival analysis and Cox hazard ratios. RESULTS: In all, 26,847 adults with schizophrenia were studied. Oral second-generation antipsychotics were more frequently dispensed than the other antipsychotic groups studied. Median treatment persistence times were 18.3 months for second-generation antipsychotic long-acting injectables, 10.7 months for oral second-generation antipsychotics and were significantly lower for both formulations of first-generation antipsychotics at 5.2 months (long-acting injectables) and 3.7 months (oral). The median persistence time for clozapine was significantly longer than all other antipsychotics groups. CONCLUSIONS: Oral second-generation antipsychotics and second-generation antipsychotic long-acting injectables accounted for over 75% and 13% of all antipsychotics in Australia, respectively. Concerns over medication adherence and subsequent relapse have not translated into increased long-acting injectable usage despite their significantly longer persistence. Clozapine, the single most 'persistent' antipsychotic, was only used in 9% of people, although up to a third of all cases are likely to be treatment-resistant. Our data suggest clinicians should give consideration to the earlier use of second-generation antipsychotic long-acting injectables and clozapine, to ameliorate prognosis in schizophrenia.

Real-World Treatment Patterns and Health-Resource Utilization in Patients with Hepatocellular Carcinoma (HCC) Following Failure of Sorafenib: A Retrospective Chart Review of 127 Patients in South Korea.

BACKGROUND: European, US, Asian and Korean treatment guidelines all recommend sorafenib as first-line systemic therapy in patients with hepatocellular carcinoma (HCC). However, due to the emergence of several new treatments, post-sorafenib treatment patterns in real-world clinical practice are less well understood. OBJECTIVE: This study aimed to characterize current treatment patterns and healthcare resource utilization (HRU) in patients with HCC following the failure of first-line sorafenib in a real-world setting in Korea. PATIENTS AND METHODS: A chart review was conducted in 127 HCC patients who received systemic therapy or best supportive care following failure of first-line systemic treatment with sorafenib (2016-2018). Anonymized data on patient characteristics, treatment patterns, and survival were abstracted by 37 physicians in Korea. RESULTS: The mean (range) age of patients was 60 (37-79) years; 63 patients had low alpha-fetoprotein (AFP < 400 ng/mL), 64 patients had high alpha-fetoprotein (AFP ≥ 400 ng/mL). Post-sorafenib, 64 (50%) patients had systemic therapy. Regorafenib, used by 54 (84%) patients in second-line, and nivolumab monotherapy, by ten (56%) patients in third-line, were the most common therapies. Hepatologist visits and hospitalizations, at an average rate of 6.89 (95% CI 6.37-7.45) and 2.24 (95% CI 1.95-2.57) per patient-year, respectively, were the key contributors of HRU. The median overall survival (95% CI) from discontinuation of sorafenib was 13.0 (9.8-20.7), 6.5 (5.0-9.5) and 9.5 (6.7-12.3) months in the low AFP, high AFP and overall group, respectively. CONCLUSION: This real-world evidence research on treatment patterns reflected current clinical guidelines and highlighted fast progressing nature and continuing high mortality in HCC, especially among the high AFP group, underlying a need for new treatments that can lengthen survival. Results from this real-world chart review, together with existing clinical trial data, can inform future evaluations of new HCC treatments that estimate their health economic impact in Korea.

Comparison of Healthcare Resource Utilization Between Patients Who Engaged or Did Not Engage With a Prescription Digital Therapeutic for Opioid Use Disorder.

BACKGROUND: A prescription digital therapeutic (PDT) (reSET-O®) may expand access to behavioral treatment for patients with opioid use disorder (OUD) treated with buprenorphine, but long-term data on effectiveness are lacking. OBJECTIVE: To compare real-world healthcare resource utilization (HCRU) among patients who engaged with reSET-O and buprenorphine compared to similar patients in recovery treated with buprenorphine who did not fill their reSET-O script or engage with the PDT beyond week one. METHODS: A retrospective analysis of facility and clinical service claims data was conducted in adults with PDT initiation and between 12 weeks and 9 months of continuous enrollment in a health plan after initiation. Patients who filled their prescription and engaged with the therapeutic were compared to patients who filled the prescription but did not engage beyond week one (NE), and patients who did not fill the prescription (NR) (the latter two groups combined into one group hereafter referred to as "non-engagers"). Comparisons were analyzed using a repeated-measures negative binomial model of encounters/procedures, adjusted for number of days in each period. Associated cost trends assessed using current Medicare reimbursement rates. RESULTS: A total of 444 patients redeemed a prescription and engaged with the PDT (mean age 37.5 years, 63.1% female, 84% Medicaid), and 64 patients did not engage with the PDT (mean age 39.5 years, 32.8% female, 73.4% Medicaid). Total cost of hospital facility encounters was $2693 for engaged patients vs $6130 for non-engaged patients. Engaged patients had somewhat higher rates of certain clinician services. Total facility and clinician services costs for engaged vs non-engaged patients were $8733 vs $11,441, for a net cost savings over 9 months of $2708 per patient who engaged with reSET-O. CONCLUSION: Patients who engaged with an OUD-specific PDT had a net cost reduction for inpatient and outpatient services of $2708 per patient over 9 months compared to patients who did not engage with the PDT, despite similar levels of buprenorphine adherence.

Real-world changes in US health system hospital-based services following treatment with a prescription digital therapeutic for opioid use disorder.

Outcomes associated with buprenorphine therapy for the treatment of opioid use disorder (OUD) are suboptimal. reSET-O is an FDA-authorized prescription digital therapeutic (PDT) delivering neurobehavioral therapy via mobile devices to patients with OUD treated with buprenorphine. This analysis evaluated the net impact of reSET-O on medical costs among actively-engaged reSET-O patients using real-world observations. This real-world retrospective analysis of health care claims between October 2018 and October 2019 evaluated health care resource utilization up to 6 months before and 6 months after the initiation of a reSET-O prescription after accounting for the subset of patients not continuing on therapy after week 1 (non-engaged patients). Repeated-measures negative binomial models compared incidences of hospital-based encounters/procedures adjusted for days in each period as well as associated costs. The number needed to treat (NNT) to avoid an inpatient visit was calculated. Of the 351 patients who were prescribed reSET-O, 321 met the criteria of active engagement. Treatment with reSET-O was associated with a substantial reduction in medical costs of -$765,450 (-$2,385/patient, $235/patient greater than a previous analysis in which non-engaged patients were included) in the 6-month period after initiation. The gross reSET-O prescription cost of $584,415 ($1,665/patient) was substantially offset by $49,950 ($142.31/patient) in refunds to payers. The medical cost reduction in engaged patients offset the cost of the therapeutic resulting in an overall cost reduction of -$230,985 in this cohort (net savings of -$720 per patient). The number needed to treat to avoid an inpatient visit was 4.8. Engagement and continued treatment with reSET-O in patients with OUD treated with buprenorphine is associated with substantial real-world reductions in medical costs in the 6-month period following the initiation of the reSET-O prescription.

Real-world reduction in healthcare resource utilization following treatment of opioid use disorder with reSET-O, a novel prescription digital therapeutic.

INTRODUCTION: Buprenorphine medication assisted treatment (B-MAT) adherence for opioid use disorder (OUD) is suboptimal. reSET-O, an FDA-cleared prescription digital therapeutic, delivers neurobehavioral therapy (community-reinforcement approach+fluency training+contingency management) to B-MAT-treated OUD patients. METHODS: This retrospective claims study (10/01/2018-10/31/2019) evaluated healthcare resource utilization up to 6 months before/after reSET-O initiation. Repeated-measures negative binomial models compared incidences of encounters/procedures. Net change in costs was assessed. RESULTS: Among 351 patients (mean age 37; 59.5% female; 82.6% Medicaid), 334 had pharmacy claims and 240 (71.9%) received buprenorphine pre-/post-index (medication possession ratio 0.73 and 0.82, respectively; P = 0.004). Facility encounters decreased, with 45 fewer inpatient (P = 0.024) and 27 fewer emergency department (ED) visits (P = 0.247). Clinical encounters with largest changes were drug testing (638 fewer; P < 0.001), psychiatry (349 fewer; P = 0.036), case management (176 additional; P = 0.588), other pathology/laboratory (166 fewer; P = 0.039), office/other outpatient (154 fewer; P = 0.302), behavioral rehabilitation (111 additional; P = 0.124), alcohol/substance rehabilitation (96 fewer; P = 0.348), other rehabilitation (66 fewer; P = 0.387), mental health rehabilitation (61 additional; P = 0.097), and surgery (60 fewer; P = 0.070). Changes in facility/clinical encounters saved $2,150/patient. CONCLUSION: reSET-O initiation was associated with fewer inpatient, ED, and other clinical encounters, increased case management/rehabilitative services, and lower net costs over six months. EXPERT OPINION: Real-world evidence is helpful in evaluating the effectiveness of interventions in usual-care conditions, outside of controlled research environments. Large observational studies based on health care claims are important to understand the actual pharmacoeconomic and outcomes impact of interventions at the health care system and population level.

Associations between seizure severity change and patient characteristics, changes in seizure frequency, and health-related quality of life in patients with focal seizures treated with adjunctive eslicarbazepine acetate: Post hoc analyses of clinical trial results.

The relationships between seizure severity change and patient characteristics, changes in seizure frequency, and health-related quality of life (HRQoL) may be important for determining the overall impact of medication therapy on patients with epilepsy. The objectives of these post hoc analyses of the global Phase III 093-0304 trial (NCT00988429, Study 304) of adjunctive eslicarbazepine acetate (ESL) in patients with refractory focal (partial-onset) seizures (FS) were to evaluate associations between seizure severity change, measured by the Seizure Severity Questionnaire (SSQ), and 1) patient characteristics, 2) seizure frequency change, standardized as the seizure frequency (SSF) per 28-day period, and 3) change in HRQoL, evaluated by the Quality of Life in Epilepsy Inventory-31 (QOLIE-31) and the Montgomery-Åsberg Depression Rating Scale (MADRS). The analyses were conducted on the per-protocol population (PPP) of patients who were randomized to a placebo arm (n = 188) or an ESL-active group that included treatment with adjunctive ESL 800 mg once daily (QD; n = 184) or adjunctive ESL 1200 mg QD (n = 175). General linear models (GLM) were used to measure the association between SSQ change and patient baseline characteristics or percentage change in the SSF from baseline. Associations between changes in the SSQ and changes in the QOLIE-31 and MADRS were examined using GLM with patient baseline characteristics as covariates. Subgroup analyses were performed for patients in the ESL-active group and those treated with ESL 800 mg or ESL 1200 mg. Minimal clinically important difference (MCIDs) thresholds were used to assess improvements in SSQ scores. The analyses included 547 per-protocol patients. Patients using 1 antiepileptic drug (AED) at baseline had greater improvements in the SSQ compared with those receiving 2 AEDs (P = 0.0606). Treatment with ESL 1200 mg was significantly associated with clinically meaningful improvements in the SSQ (P = 0.0005). The SSQ improvements were significantly associated with an SSF reduction of ≥75%, compared with no reduction (P < 0.0001). In the PPP and the ESL-active group, SSQ improvements were significantly associated with improvements in QOLIE-31 Total Score (TS; P < 0.0001) and the Seizure Worry (SW; P < 0.0001) and Social Functioning (SF; P = 0.0030) subscales. In the ESL 1200 mg subgroup, SSQ improvements were significantly associated with improvements in QOLIE-31 TS (P < 0.0001) and the SW (P < 0.0001) and Energy/Fatigue (EF; P = 0.0007) subscales. In the ESL 800 mg subgroup, improvements in the SSQ were significantly associated with improvements in QOLIE-31 TS (P = 0.0362) and the SW (P = 0.0241) subscale. There was no significant association between changes in the SSQ and changes in the MADRS in patients treated with ESL. These findings demonstrated that in this clinical trial population, adding ESL to baseline AED therapy had utility for decreasing seizure severity and improving HRQoL. There were no significant associations between changes in seizure severity and changes in depressive symptoms in patients with FS.

Economic Burden of Checkpoint Inhibitor Immunotherapy for the Treatment of Non-Small Cell Lung Cancer in US Clinical Practice.

PURPOSE: The efficacy of checkpoint inhibitor (CPI) immunotherapy in patients with non-small cell lung cancer (NSCLC) is limited by a lack of strongly predictive response markers, subjecting patients to potential underutilization of alternative effective treatments, increased risk for futile care, and unnecessary costs. Here, we characterize the extent to which basic molecular tumor-marker testing has been performed for NSCLC therapy selection in the United States, and compare medical resource utilization and costs in CPI-treated patients versus CPI-eligible patients treated with other therapies. METHODS: We identified a cohort of CPI-treated patients with NSCLC and a propensity score-matched cohort of CPI-eligible patients with NSCLC treated with non-CPI therapies (3095 patients in each group), using US administrative claims data covering the pre- and postinitial FDA-approval period for nivolumab, pembrolizumab, and atezolizumab (October 2012 to September 2017). We describe the utilization of recommended baseline molecular testing for CPI selection (pre-index date for CPI or other anticancer therapy), including programmed death ligand 1 (PD-L1) immunohistochemistry, ALK rearrangement and EGFR mutation testing, and pre- and postindex treatment patterns. All-cause medical resource utilization and semiannual total reimbursement (costs) were compared between CPI-treated and non-CPI-treated patients. FINDINGS: At baseline, in the propensity score-matched CPI- and non-CPI-treated patient cohorts, mean PD-L1 immunohistochemistry test utilization for CPI selection was moderate (0.6 vs 0.7 per patient, respectively). However, we observed much lower mean utilization of testing for EGFR mutations (0.1 vs 0.1 per patient) and ALK rearrangements (0.1 vs 0.2 per patient). Postindex, the use of both chemotherapy and ALK- and EGFR-targeted therapies were decreased in both cohorts. The CPI-treated group had significantly higher mean medical resource utilization in nearly all categories in the postindex period, and total per-patient semiannual costs, than did the CPI-eligible patients who received other therapies (141,537 vs 75,429 US dollars [USD]; P < 0.0001), driven by CPI drug reimbursement. Median (interquartile range) time on CPI was longest with pembrolizumab (113 [106-127] days), followed by nivolumab (105 [97-106] days) and atezolizumab (64 [50-85] days). Despite being associated with the lowest drug cost and the shortest treatment duration, atezolizumab was associated with the highest mean total per-patient semiannual costs (160,540 USD) compared with pembrolizumab (153,003 USD) and nivolumab (138,542 USD). IMPLICATIONS: The advent of CPI treatment for NSCLC has added substantial care-related costs for patients and payers, concurrent with underutilization of minimum recommended molecular testing for therapy selection. Broad uptake of panel-based comprehensive targeted-therapy and immunotherapy profiling can promote optimal treatment selection and sequencing, reduce the likelihood of futile treatment, and further improve patient outcomes.

Health-Related Quality of Life as Measured by the 12-Item Short-Form Survey Among Adults With Community-Acquired Bacterial Pneumonia who Received Either Lefamulin or Moxifloxacin in 2 Phase III Randomized, Double-Blind, Double-Dummy Clinical Trials.

BACKGROUND: Interest in patient-reported outcomes (PROs) as part of benefit-risk assessment for new drug approvals is increasing. Lefamulin is the first intravenous (IV) and oral pleuromutilin antibiotic for treatment of adults with community-acquired bacterial pneumonia (CABP). Assessment of health-related quality of life (HRQoL) was prospectively incorporated in its CABP trials (Lefamulin Evaluation Against Pneumonia [LEAP] 1 and 2) via the 12-Item Short-Form Survey (SF-12), a widely used PRO that measures general health status in 8 domains. METHODS: HRQoL was evaluated by SF-12 at baseline and test of cure (TOC; 5-10 days after the last study drug dose) in patients who received lefamulin or moxifloxacin in LEAP 1 (IV/oral treatment) and LEAP 2 (oral-only treatment). SF-12 outcomes included the 8 domains, physical component and mental component summary scores, and the Short-Form Six-Dimension health utility score. RESULTS: Analysis included 1215 patients (lefamulin: n = 607; moxifloxacin: n = 608). At baseline, all mean SF-12 scores in both treatment groups were well below the United States reference mean. Clinically meaningful and significant improvements from baseline to TOC were observed in all SF-12 scores. No significant differences in mean score improvements from baseline to TOC between treatment groups were observed. SF-12 score improvements at TOC across predefined subgroups were comparable between treatment groups. CONCLUSIONS: Results indicate that adults with CABP experienced comparable HRQoL improvements with lefamulin relative to moxifloxacin, and treatment with either agent resulted in returns to population norm HRQoL levels. These data suggest that lefamulin is a potential alternative to moxifloxacin for treatment of adults with CABP.

Exhalation delivery system with fluticasone improves quality of life and health status: pooled analysis of phase 3 trials NAVIGATE I and II.

BACKGROUND: Chronic rhinosinusitis with or without nasal polyps (CRSwNP/CRSsNP) seriously impairs health-related quality of life (HRQoL). This analysis describes the impact of the exhalation delivery system with fluticasone (EDS-FLU) on HRQoL, assessed by the 36-item Short-Form Health Survey version 2 (SF-36v2), and on utilities, assessed via the Short-Form 6-Dimension (SF-6D), in patients with CRSwNP. METHODS: Post hoc analysis of pooled randomized clinical trial data (NAVIGATE I and II; N = 643) to examine change from baseline in SF-36v2 and SF-6D at end-of-double-blind (EODB: 16 weeks) and end-of-open-label (EOOL: 24 weeks; following 8 weeks of open-label treatment) for EDS-FLU vs placebo (EDS-PBO). Baseline characteristics predictive of change in SF-36 and SF-6D scores were assessed. RESULTS: Mean baseline SF-36v2 scores were below population norms. At EODB, mean improvement was greater for all SF-36v2 domain and component scores with EDS-FLU (range: 2.9 [physical functioning] to 5.11 [bodily pain {BP}]) vs EDS-PBO (range: 0.81 [mental health] to 2.87 [BP]) (each comparison p < 0.01); physical and mental component score improvements within the EDS-FLU group exceeded the minimal clinically important difference (MCID). Clinically meaningful and statistically significant improvements in SF-6D utility scores were seen in EDS-FLU-treated patients compared to EDS-PBO-treated patients (0.058 vs 0.023, respectively, p < 0.001). At EOOL, SF-36v2 and SF-6D mean scores were at or above population norms, with clinically meaningful and statistically significant improvements from baseline. CONCLUSION: In this pooled analysis of 2 large pivotal EDS-FLU trials, health domain and health utilities improvements were significantly greater with EDS-FLU than EDS-PBO and were comparable to population norms.

Post Hoc Assessment of Time to Clinical Response Among Adults Hospitalized with Community-Acquired Bacterial Pneumonia Who Received Either Lefamulin or Moxifloxacin in 2 Phase III Randomized, Double-Blind, Double-Dummy Clinical Trials.

Time to clinical response, a proxy for hospital "discharge readiness," was compared between CABP inpatients who received lefamulin or moxifloxacin in the Lefamulin Evaluation Against Pneumonia (LEAP) trials. The analysis included 926 inpatients. A short and comparable median time to clinical response (4 days) was observed in both treatment groups.

Evaluation of pain relief treatment and timelines in emergency care in six European countries and Australia.

PURPOSE: Inadequate relief of pain is common in prehospital and hospital emergency department (ED) settings. We investigated pain treatments and timelines in patients receiving pre-hospital and hospital ED care to provide insight into potential approaches to reduce the burden of trauma-related pain. PATIENTS AND METHODS: In this observational, retrospective chart review, patients had received emergency care for musculoskeletal trauma injuries and analgesic treatment for moderate-to-severe pain in Belgium, France, Germany, Italy, Spain or Sweden. As inhaled low-dose methoxyflurane (LDM) is used extensively in Australia but was not widely available in Europe at the time of this analysis, data from Australia were collated to provide insight into the potential utility of this analgesic in Europe. The primary endpoint was time to administration of first pain relief treatment following arrival of paramedic/ED care. RESULTS: Randomly selected physicians (n=189) collated data from 856 patients (Europe: n=585; Australia: n=271) via an online survey. Time to first pain relief treatment varied between countries and was significantly longer across Europe versus Australia (mean [SD] 38.1 [34.7] vs 29.9 [35.5] mins; P=0.0017). Patients from Australia who received LDM experience a shorter mean (SD) time to first pain treatment following arrival of emergency care versus patients who received other analgesics (propensity score matched [n=85] per group: 21.7 [24.2] vs 39.1 [43.0] mins; P=0.0013). Across all countries, mean (SD) time to first analgesic was shorter when treatment was administered by paramedics versus hospital ED staff (15.7 [14.7] vs 49.1 [38.4] mins). CONCLUSIONS: While there was a large variation in analgesia timelines across countries, mean times are shorter in Australia compared with Europe overall. In Australia, use of LDM was associated with a significantly shorter time from emergency assistance to first pain treatment compared with non-LDM treatments. Further studies are needed to investigate the utility of LDM in Europe.

Renal impairment and use of nephrotoxic agents in patients with multiple myeloma in the clinical practice setting in the United States.

Renal impairment is a common complication of multiple myeloma and deterioration in renal function or renal failure may complicate clinical management. This retrospective study in patients with multiple myeloma using an electronic medical records database was designed to estimate the prevalence of renal impairment (single occurrence of estimated glomerular filtration rate [eGFR] <60 mL/min per 1.73 m2 on or after multiple myeloma diagnosis) and chronic kidney disease (at least two eGFR values <60 mL/min per 1.73 m2 after multiple myeloma diagnosis that had been measured at least 90 days apart), and to describe the use of nephrotoxic agents. Eligible patients had a first diagnosis of multiple myeloma (ICD-9CM: 203.0x) between January 1, 2012 and March 31, 2015 with no prior diagnoses in the previous 6 months. Of 12,370 eligible patients, the prevalence of both renal impairment and chronic kidney disease during the follow-up period was high (61% and 50%, respectively), and developed rapidly following the diagnosis of multiple myeloma (6-month prevalence of 47% and 27%, respectively). Eighty percent of patients with renal impairment developed chronic kidney disease over the follow-up period, demonstrating a continuing course of declining kidney function after multiple myeloma diagnosis. Approximately 40% of patients with renal impairment or chronic kidney disease received nephrotoxic agents, the majority of which were bisphosphonates. As renal dysfunction may impact the clinical management of multiple myeloma and is associated with poor prognosis, the preservation of renal function is critical, warranting non-nephrotoxic alternatives where possible in managing this population.

The impact of multiple sclerosis severity on health state utility values: Evidence from Australia.

BACKGROUND: The measurement of health state utility values (HSUVs) for a representative sample of Australian people with multiple sclerosis (MS) has not previously been performed. OBJECTIVES: Our main aim was to quantify the HSUVs for different levels of disease severities in Australian people with MS. METHOD: HSUVs were calculated by employing a 'judgement-based' method that essentially creates EQ-5D-3L profiles based on WHOQOL-100 responses and then applying utility weights to each level in each dimension. A stepwise linear regression was used to evaluate the relationship between HSUVs and disease severity, classified as mild (Expanded Disability Status Scale (EDSS) levels: 0-3.5), moderate (EDSS levels: 4-6) and severe (EDSS levels: 6.5-9.5). RESULTS: Mean HSUV for all people with MS was 0.53 (95% confidence interval (CI): 0.52-0.54). Utility decreased with increasing disease severity: 0.61 (95% CI: 0.60-0.62), 0.51 (95% CI: 0.50-0.52) and 0.40 (95% CI: 0.38-0.43) for mild, moderate and severe disease, respectively. Adjusted differences in mean HSUV between the three severity groups were statistically significant. CONCLUSION: For the first time in Australia, we have quantified the impact of increasing severity of MS on health utility of people with MS. The HSUVs we have generated will be useful in further health economic analyses of interventions that slow progression of MS.

A Comparative Study of Treatment-Emergent Adverse Events Following Use of Common Bowel Preparations Among a Colonoscopy Screening Population: Results from a Post-Marketing Observational Study.

BACKGROUND: Colonoscopy may be one of the most frequent elective procedures in older adults and is associated with a low occurrence of complications. However, reduction of risks attributable to the bowel preparation may be achieved with the use of effective and safer products. AIM: The aim of this study was to examine the incidence of treatment-emergent adverse events (TEAEs) associated with SUPREP(®) [oral sulfate solution (OSS)] and other common prescription bowel preparations (non-OSS). METHODS: This real-world, observational study used de-identified health insurance claims and laboratory results to identify TEAEs in the 3 months following screening colonoscopy in adults with a prescription for a bowel preparation in the prior 60 days. The unadjusted and adjusted (controlling for patient risk factors) cumulative incidences of TEAEs were estimated using Kaplan-Meier and Poisson regression, respectively. RESULTS: Among patients ≥45 years, the overall cumulative incidence was significantly lower (p < 0.001) in the OSS cohort than in the non-OSS cohort (unadjusted: 2.31 vs. 2.89 %; adjusted: 1.61 vs. 1.95 %), with significantly lower acute cardiac conditions (1.56 vs. 1.90 %; p < 0.001), renal failure/other serious renal diseases (OSS: 0.21 %, non-OSS: 0.32 %; p < 0.001), and serum electrolyte abnormalities (OSS: 0.39 %, non-OSS: 0.49 %; p = 0.017). There were no significant differences between cohorts in death, seizure disorders, aggravation of gout, and ischemic colitis. Results were similar in the adjusted cumulative incidences. CONCLUSIONS: In actual use, the overall cumulative incidence of TEAEs was significantly lower in the OSS cohort, demonstrating that OSS is as safe as, or possibly safer than, non-OSS prescription bowel preparations.

The economic impact of multiple sclerosis in Australia in 2010.

BACKGROUND: Multiple sclerosis (MS) has a major impact on health and is a substantial burden on patients and society. We estimated the annual costs of MS in Australia from individual and societal perspectives using data from the Australian MS Longitudinal Study (AMSLS) and prevalence figures from 2010. METHODS: Direct and indirect costs were estimated from a subsample of 712 AMSLS subjects who completed baseline and follow-up economic impact surveys. All costs are in 2010 Australian dollars (AUD). RESULTS: Annual costs per person with MS were AUD48,945 (95% CI: 45,138 to 52,752). Total costs were AUD1.042 (0.9707 to 1.1227) billion based on a prevalence of 21,283. The largest component was indirect costs due to loss of productivity (48%). Costs increased with increasing disability: AUD36,369, AUD58,890 and AUD65,305 per patient per year for mild, moderate and severe disability, respectively. Total costs of MS to Australian society have increased 58% between 2005 and 2010. CONCLUSIONS: This study confirms that MS imposes a substantial burden on Australian society, particularly impacting on productivity. The burden increases with worsening disability associated with the disease. Investment in interventions that slow progression, as well as resources, services and environments that assist people with MS to retain employment, is supported.
