Treatment patterns in patients with newly diagnosed COPD in the USA.

BACKGROUND: Prompt and effective management with maintenance therapy (single or dual bronchodilator therapy) is recommended after the initial diagnosis of chronic obstructive pulmonary disease (COPD) to maintain lung function and prevent exacerbations. Contrary to guideline-based recommendations, most patients are not prescribed maintenance treatment at initial diagnosis. The current study assessed the pharmacologic treatment patterns and outcomes of newly diagnosed patients with COPD in the USA. METHODS: This retrospective, noninterventional study used de-identified data from the Inovalon Insights' database (Commercial, Medicaid Managed Care, and Medicare Advantage-insured individuals) between January 1, 2015, and December 31, 2021. The "patient journey" from initial diagnosis was followed over a 4-year period. The primary outcome measure was the number of moderate or severe exacerbations. Secondary outcome measures included the cumulative incidence of exacerbations, mean cumulative count of moderate and severe exacerbations, rates of moderate and severe exacerbations in patients who remained untreated after diagnosis in 12-month time periods for 4 years, sociodemographic and clinical characteristics, and pharmacologic treatment patterns. RESULTS: The cohort consisted of 238,158 newly diagnosed patients with COPD (female [52.9%]; mean age 63.8 years). The majority of patients with COPD had Medicaid as their primary insurance (46.2%). Overall, during the 4-year follow-up period, 32.9% of the patients had at least one moderate or severe exacerbation, and 25.8% and 13.8% experienced moderate and severe exacerbations, respectively. At diagnosis, 86.2% of the patients were untreated and most remained untreated by the end of the follow-up (63.8%). Most patients (62.0%) received long-acting beta-agonist (LABA)/inhaled corticosteroids (ICS) as their initial treatment at diagnosis, and LABA/ICS continued to be the most common initial treatment during the 4-year period (64.0% at year 1; 58.0% at year 4). CONCLUSIONS: Most patients with COPD were not treated at initial diagnosis and remained untreated during follow-up. Our data highlight a lack of adherence to recommendations for clinical practice.

Treatment patterns of patients with migraine eligible for anti-CGRP pathway monoclonal antibodies.

Introduction: Migraine is a debilitating neurological disorder, with a wide range of symptoms and disease burden, underscoring the heterogeneity of patients' disease characteristics and treatment needs. To characterize the profile of migraine patients in the US who may be eligible for preventive treatment with an anti-CGRP pathway mAb and to better understand treatment patterns and real-world use of acute and preventive medications for migraine, we conducted a retrospective cohort study of adult patients. Methods: These patients were identified as having migraine using diagnosis codes or migraine-specific medication use (first = index) in the IQVIA PharMetrics® Plus database. Patients were required to have ≥ 12 months of continuous enrollment in medical and pharmacy benefits prior to index (baseline) and after index (follow-up). Patients were stratified into chronic migraine (CM) and non-chronic migraine (non-CM) by diagnosis codes. Based on acute migraine-specific medication dispensing data in the follow-up period, non-CM patients were divided into 3 cohorts: highest, middle, and lowest tertile of total units of dispensed acute migraine-specific medication (gepants, ditans, ergot derivatives, and triptans). Migraine medication use was captured in the baseline and follow-up periods. Results: A total of 22,584 CM and 216,807 non-CM patients (72,269 patients in each tertile) were identified and included in the study. Over the follow-up, CM patients had a mean of 70 units of acute migraine-specific medications dispensed, while the highest, middle, and lowest tertile of non-CM patients had a mean of 92, 29, and 10 units, respectively. Anti-calcitonin gene-related peptide pathway mAbs were dispensed for 28.9% of CM patients, and for 6.9%, 4.1%, and 2.9% of non-CM patients in the highest, middle, and lowest tertiles, respectively. Conclusion: A lower proportion of non-CM patients had use of anti-calcitonin gene-related peptide pathway mAbs compared to CM patients, confirming the unmet need with appropriate preventive medication. There appears to be a persistent gap in management of patients without a diagnosis of CM who are dispensed high quantities of acute migraine-specific medications.

Real-world first-line treatment patterns and outcomes in recurrent/advanced endometrial cancer patients in Europe.

Background: The treatment patterns and clinical outcomes in recurrent/advanced endometrial cancer in Europe are not well known. Materials & methods: Endometrial Cancer Health Outcomes-Europe-First-Line is a multicenter, retrospective chart review study conducted in the UK, Germany, Italy, France and Spain. Patients diagnosed with recurrent/advanced endometrial cancer who initiated first-line systemic therapy between 1 July 2016 and 31 March 2020 were eligible. Results: Among 242 patients, median age was 69 years and 82.2% had stage IIIB-IV disease. In first-line, most patients received platinum-based chemotherapy (78.9%); others received endocrine therapy (6.2%), taxane monotherapy (5.8%) and nonplatinum or taxane-based chemotherapy (4.1%). Median real-world progression-free survival since first-line initiation was 10.8 months and median overall survival was 20.7 months. Conclusion: Poor prognosis with platinum-based first-line chemotherapy suggests significant unmet medical need.

Treatment patterns & survival for recurrent/advanced endometrial cancer patients in Europe who received their first treatmentThe treatments and survival for recurrent/advanced endometrial (uterus lining) cancer patients in real-life European settings are not well known. Endometrial Cancer Health Outcomes-Europe-First-Line is a multicenter study that was conducted in the UK, Germany, Italy, France and Spain and used de-identified information from existing patient medical records. Patients diagnosed with recurrent/advanced endometrial cancer who initiated a first treatment between 1 July 2016 and 31 March 2020 were included. Among 242 included patients, the average age was 69 years and 82.2% had stage IIIB-IV disease (indicating the size and extent of their cancer). As their first treatment, most patients received platinum-based chemotherapy (78.9%), which is a type of drug that kills cancer cells. Overall, patients lived for an average of 20.7 months since their first treatment. The average length of time patients lived without their disease getting worse was 10.8 months since their first treatment. We found that patients who received platinum-based chemotherapy as their first treatment had poor survival, which suggests significant unmet medical need.

From Triple- to Penta-Exposed Multiple Myeloma: A Real-World Study in a Medicare Population.

INTRODUCTION: Treatment of multiple myeloma (MM) has been transformed by novel therapies, including CD38 monoclonal antibodies (mAbs), immunomodulatory drugs (IMiDs), and proteasome inhibitors (PIs), resulting in increasing numbers of patients who are triple-class exposed (TCE; exposed to ≥ 1 drug in each class). Many patients are penta-exposed (PE; ≥ 2 IMiDs, ≥ 2 PIs, and a CD38 mAb), some are triple-class refractory (TCR), and some are PE and TCR (PE-TCR). Data on real-world outcomes in elderly patients with MM across this spectrum of exposure are limited. METHODS: Data from the Medicare Chronic Conditions Warehouse Database from November 2006-December 2020 were used to examine cohorts of TCE, TCR, PE, and PE-TCR patients. Outcomes were assessed from the start of the index line of therapy (LOT), defined as the first LOT after becoming TCE or PE. RESULTS: A total of 2830 TCE, 1371 TCR, 1121 PE, and 774 PE-TCR patients were identified. Pomalidomide was the most frequently used medication for the index LOT in all cohorts (32.6% [PE-TCR] to 43.3% [TCR]). The most frequently used regimens for the index LOT were pomalidomide plus daratumumab for TCE (17.2%) and PE (7.0%), pomalidomide plus carfilzomib for TCR (10.3%), and pomalidomide plus elotuzumab for PE-TCR (7.4%). Median time to discontinuation (TTD) ranged from 4.2 (PE-TCR) to 6.9 (TCE) months, and overall survival (OS) ranged from 13.0 (TCR) to 15.9 (PE) months. Healthcare resource utilization (HRU) was lowest for TCE and highest for PE-TCR patients. Mean monthly healthcare costs (HCC) ranged from $23,091 (TCE) to $24,412 (PE-TCR). MM medications represented 66.2% (PE-TCR) to 72.8% (TCE) of costs. CONCLUSIONS: In this study across a spectrum of Medicare TCE patients, there was heterogeneity in treatment regimens, suggesting no standard of care. TTD and OS were short, and HRU and HCC were high. These results underscore the potential for new therapies in this population.

Ixekizumab Treatment Patterns and Health Care Resource Utilization Among Patients with Axial Spondyloarthritis: A Retrospective United States Claims Database Study.

INTRODUCTION: Real-world data on ixekizumab utilization in axial spondyloarthritis (axSpA) are limited. We evaluated ixekizumab treatment patterns and health care resource utilization (HCRU) in patients with axSpA using United States Merative L.P. MarketScan® Claims Databases. METHODS: This retrospective cohort study included adults with axSpA who initiated ixekizumab during the index period (September 2019-December 2021). Index date was the date of the first ixekizumab claim. All patients had continuous medical and pharmacy enrollment during the 12-month pre-index and follow-up periods. Descriptive statistics were used to assess patient demographics (index date); clinical characteristics (pre-index period); treatment patterns (12-month follow-up period); and HCRU (pre-index and 12-month follow-up periods). RESULTS: The study included 177 patients (mean age 45.8 years; females 54.8%) with axSpA who initiated ixekizumab. Overall, 79.1% of patients reported prior biologic use; of these, 70.7% received tumor necrosis factor-alpha inhibitors (TNFi) and 49% received secukinumab. The mean (standard deviation [SD]) Charlson Comorbidity Index score was 1.1 (1.3) and ~ 27% of patients reported ≥2 comorbidities. The median (inter-quartile range [IQR]) number of ixekizumab prescription refills was 7 (4-11). The mean (SD) Proportion of Days Covered (PDC) for ixekizumab was 0.6 (0.3) and adherence (PDC ≥80%) was 34.5% (N = 61). Overall, 26.6% (N = 47) of patients switched to a non-index medication and 54.2% (N = 96) of patients discontinued ixekizumab. Among the patients who discontinued ixekizumab (N = 96), 19.8% (N = 19) restarted ixekizumab and 49.0% (N = 47) switched to a non-index medication. The median (IQR) ixekizumab persistence was 268 (120-366) days. Mean axSpA-related outpatient, inpatient, and emergency room visits were similar between the pre-index and follow-up periods. Treatment patterns were largely similar between biologic-experienced patients (N = 140; 79.1%) and the overall population. CONCLUSIONS: Despite high comorbidity burden and majority of the patients being biologic-experienced, patients initiating ixekizumab for axSpA showed favorable persistence profiles during the 12-month follow-up period.

Axial spondyloarthritis (axSpA) affects the patients' ability to perform daily activities and can have a major impact on their quality of life. Ixekizumab is approved in the United States for the treatment of axSpA. However, real-world data on utilization of ixekizumab are limited. We used administrative claims databases to evaluate real-world treatment patterns and health care resource utilization in adult patients with axSpA who were receiving ixekizumab in the United States. The study showed that more than a quarter of the patients receiving ixekizumab had at least two comorbidities. A majority of the patients (79%) reported that they had received at least one biologic before initiating ixekizumab. Even with the high comorbidity burden and the previous exposure to biologics, patients showed favorable persistence to ixekizumab. Of the patients who discontinued ixekizumab, subsequently, 20% re-initiated ixekizumab and approximately half of the patients switched to an alternative medication. There was no increase in axSpA-related health care resource utilization following ixekizumab treatment. The study findings suggest that ixekizumab is an effective treatment option for patients with axSpA.

Real-world treatment patterns, resource utilization and costs in biliary tract cancers in the USA.

Aim: To evaluate real-world treatment patterns, survival and healthcare-resource utilization in US patients with advanced biliary tract cancers (BTC) receiving systemic therapy.Patients & methods: This study used claims data from the Healthcare Integrated Research Database (HIRD®) linked to clinical data from the Cancer Care Quality Program (January 1, 2015-September 30, 2020).Results: Of 413 patients, 84.5% received gemcitabine-based first-line (1L) treatment, 46% received second-line treatment, and 16.5% received third-line (3L) treatment. All-cause mortality was 53% and approximately 70% of patients had ≥1 inpatient visit. The total mean per-patient-per-month all-cause costs were $19,589 for 1L and $33,534 for 3L treatment.Conclusion: Results showed poor survival, significant resource use and high costs as treatment line progresses for patients with advanced BTC.

Our research explored which treatments US patients with advanced biliary tract cancers (BTC) received and how long they lived for. We analyzed information from a US database, called the Healthcare Integrated Research Database (HIRD®), which holds information related to healthcare insurance claims. Out of 413 patients in the database, 84.5% were initially given a combination treatment involving a chemotherapy called gemcitabine. We also found that 46% of patients received a type of second treatment (also known as second-line therapy), and 16.5% received a third treatment (third-line therapy). During treatment, around 70% of patients needed to stay in hospital at least once. The cost of healthcare was more expensive for patients receiving later lines of therapy, with the average monthly cost per patient for first-line treatment being $19,589 and third-line treatment being $33,534. Furthermore, just over half of the 413 patients died from any causes, showing the poor outlook these patients face. This information is important for understanding the real-world management of patients with BTC, so that their care can be improved in the future.

Abemaciclib for treating patients with HR+/HER2- metastatic breast cancer: a real-world study in France, Italy and Spain.

Aim: This real-world study aimed to describe patient and clinical characteristics, treatment patterns and outcomes for patients with HR+/HER2- metastatic breast cancer receiving abemaciclib in France, Italy and Spain. Materials & methods: A multicenter chart review was conducted for adult females with HR+/HER2- advanced/metastatic breast cancer who received abemaciclib in routine care. Real-world progression-free survival (rwPFS) was estimated via Kaplan-Meier curves. Results: This study included 151, 173 and 175 patients from France, Italy and Spain, respectively. Abemaciclib was mostly prescribed as first-line therapy concomitantly with hormone therapy. Median rwPFS was >20 months and the 1-year rwPFS rate was >70%. Conclusion: Effectiveness was similar across the three countries and aligns with pivotal studies.

Abemaciclib use in the clinic in France, Italy & SpainThis study describes patients, the treatments they have received and the results of those treatments for patients with the most common type of advanced breast cancer. These patients were taking abemaciclib plus hormonal therapy in routine breast cancer care in France, Italy and Spain. The information used to conduct this study was taken from patients' medical charts. In this real-world study, abemaciclib was mostly used as the initial treatment for advanced breast cancer. Abemaciclib effectiveness was similar across the three countries confirming findings from previous studies. Our study supports the use of abemaciclib for patients with HR+/HER2- advanced breast cancer.

Treatment characteristics and outcomes in lower-risk, non-del(5q) myelodysplastic syndromes: findings from a medical record review in the USA, Canada and Europe.

Aim: To assess treatment patterns and outcomes in patients with non-del(5q) lower-risk myelodysplastic syndromes. Methods: Patient medical records were reviewed in the USA, Canada (CAN), UK and the EU. Results: Analysis included 119 patients in the USA/CAN (median age, 61.5 years) and 245 patients in the UK/EU (median age, 67.3 years). Most patients received erythropoiesis-stimulating agents (ESAs) as first-line (1L) therapy (USA/CAN: 89.0%; UK/EU: 90.2%). A substantial proportion of 1L erythropoiesis-stimulating agent-treated patients were transfusion dependent before 1L (USA/CAN: 37.1%; UK/EU: 51.2%); a small percentage of these patients achieved transfusion independence during 1L therapy (USA/CAN: 2.8%; UK/EU: 14.4%). Conclusion: These findings highlight an unmet need for more effective treatments among patients with non-del(5q) lower-risk myelodysplastic syndromes.

Demographic characteristics, diagnostic challenges, treatment patterns, and caregiver burden of mitochondrial diseases: a retrospective cross-sectional study.

BACKGROUND: This study aimed to explore the demographic characteristics, diagnostic challenges, treatment patterns, and caregiver burden of mitochondrial diseases. METHODS: This retrospective cross-sectional study enrolled patients diagnosed with mitochondrial diseases from the Department of Neurology at Peking University First Hospital between January 2010 and December 2021. A questionnaire covering demographic characteristics, diagnostic dilemma, treatment, economic aspects, and caregiver stress was administered, and disability was assessed using the modified Rankin Scale (mRS). RESULTS: A total of 183 patients (mean age: 16 (IQR: 12-25), 49.72% males) were enrolled, including 124 pediatric patients and 59 adult patients. MELAS (106. 57.92%) and Leigh syndrome (37, 20.22%) were predominant among the mitochondrial disease subtypes. Among them, 132 (72.13%) patients were initially misdiagnosed with other diseases, 58 (31.69%) patients visited 2 hospitals before confirmed as mitochondrial disease, and 39 (21.31%) patients visited 3 hospitals before confirmed as mitochondrial disease. Metabolic modifiers were the most common type of drugs used, including several dietary supplements such as L-carnitine (117, 63.93%), Coenzyme Q10 (102, 55.74%), idebenone (82, 44.81%), and vitamins (99, 54.10%) for proper mitochondrial function. Mothers are the primary caregivers for both children (36.29%) and adults (38.98%). The mRS score ranged from 0 to 5, 92.35% of the patients had different degrees of disability due to mitochondrial disease. The average monthly treatment cost was 3000 RMB for children and 3100 RMB for adults. CONCLUSIONS: This study provided valuable insights into the characteristics and challenges of mitochondrial diseases, which underscores the need for improved awareness, diagnostic efficiency, and comprehensive support for patients and caregivers.

A Retrospective Analysis of Disease Epidemiology, Comorbidity Burden, Treatment Patterns, and Healthcare Resource Utilization of Migraine in the United Arab Emirates.

INTRODUCTION: Migraine is a recurrent, disabling neurological disorder with a substantial global disease burden. However, limited real-world data are available on the patient characteristics, treatment patterns, comorbidities, and economic burden of migraine in the United Arab Emirates (UAE). In this study, we evaluated the disease burden, comorbidities, treatment patterns, specialties involved in migraine diagnosis, and healthcare resource utilization (HCRU) and associated costs in patients with migraine in Dubai, UAE. METHODS: A retrospective, secondary database cohort study was conducted from 01 January 2014 to 31 March 2022 using the Dubai Real-World Database. Patients aged ≥ 18 years with at least one diagnosis claim for migraine with continuous enrollment during the study period were included. Patients were stratified into treatment sub-cohorts. Outcomes were evaluated in terms of clinical characteristics, comorbidities, specialists visited, treatment patterns, and HCRU. RESULTS: The study included 203,222 patients (mean age: 40 years), with male predominance (55.4%). About 13.4% of patients had specific cardiovascular comorbidities. Frequently prescribed drug classes were nonsteroidal anti-inflammatory drugs (84.4%), triptans (29.8%), and beta-blockers (12.8%), while only 1.0% of patients with migraine were prescribed newer medications like calcitonin gene-related peptide antagonists. General medicine was the most frequently visited specialty on the index date (51.5%). The all-cause and migraine-specific median gross costs during the 12-month post-index period were US $1252.6 (2.4-564,740.7) and US $198.1 (0-168,903.3) respectively, with maximum contribution from inpatients. The contribution of migraine-specific median costs to all-cause median costs was highest for the diagnosis-related group (64.9%), followed by consumables (35.2%), medications (32.0%), procedures (24.5%), and services (24.5%). CONCLUSION: Migraine significantly impacts healthcare costs in the UAE. The role of newer therapies in migraine management should be explored to reduce the associated socioeconomic burden and improve patients' quality of life.

Malignant melanoma in Portuguese adult population: a scoping review of the real-world evidence.

PURPOSE: Malignant melanoma is an aggressive cancer, and there is a notable dearth on epidemiology, clinical and treatment characterization within the Portuguese population. We performed a scoping review to identify real-world evidence studies focused in Portuguese adult patients with malignant melanoma. METHODS: A comprehensive search was conducted. After screening, we described the studies by design, sample size, geographics, setting, population, and outcomes reported. RESULTS: The search yielded 54 studies, mainly retrospective (79.6%). The population assessed was heterogeneous varying from patients with melanoma in general to specific types of melanoma, or even more restricted to patients with specific conditions. The evidence found was mostly concerning clinical outcomes (n=46), patients' clinical profile (n=44) and demographic characterization (n=48). Treatment information was described in 30 studies whereas only 18 reported epidemiological parameters. Studies were mainly performed by the major oncology centers in Lisbon, Oporto and Coimbra, and only two evaluated the entire Portuguese population. To allow comparability, only studies including patients with cutaneous malignant melanoma were considered (13 of the 54) for outcomes evaluation analysis. Median OS varied from 18 to 36 months, assessed after melanoma treatment. Incidence was the most reported epidemiological parameter, confirming the increasing number of cutaneous malignant melanoma patients over the years. Only one study reported prevalence and four reported mortality rates. CONCLUSIONS: The evidence found confirms the lack of information about malignant melanoma in Portugal, highlighting the need of real-world studies to assess melanoma prevalence and incidence rates, current treatment approaches, and clinical characterization of these patients.

Characterizing the journey of Rett syndrome among females in the United States: a real-world evidence study using the Rett syndrome natural history study database.

BACKGROUND: With the advent of the first targeted therapy for Rett Syndrome (RTT), a comprehensive assessment of the journey of RTT is needed to elucidate on present unmet needs in this population. This study characterized females with RTT in the United States and their disease journey with respect to longitudinal treatment patterns, RTT-related outcomes, and changes in disease severity. METHODS: This retrospective cohort study used registry data of females with RTT from the 5211 RTT Natural History Study (RNHS) (November 2015-July 2021). Pharmacological and supportive therapy use, RTT-related outcomes, and RTT severity, as measured by the Clinical Severity Scale and Motor Behavioral Assessment scale, were evaluated following the first RNHS visit. Analyses were conducted overall and in subgroups by RTT type (classic and atypical RTT) and age at first visit (pediatric and adult). RESULTS: A total of 455 females with RTT were included in the study, of whom 90.5% had classic RTT and 79.8% were pediatric individuals. Over a median follow-up of 4 years, use of pharmacological therapies, including prokinetic agents (42.7% vs. 28.3%), and supportive therapies, including physical therapy (87.3% vs. 40.2%) and speech-language therapy (86.8% vs. 23.9%), were more common in pediatric than adult individuals (all p < 0.05). Nearly half (44.6%) of all individuals had a hospital or emergency room visit, with a higher proportion of visits in individuals with classic RTT than atypical RTT and pediatric than adult individuals (both p = 0.001). An increasing trend in clinical severity was observed in pediatric individuals (mean change per year: 0.24; 95% confidence interval [CI]: 0.03, 0.44), while an increasing trend in motor-behavioral dysfunction was observed in pediatric individuals (mean change per year: 1.12; 95% CI: 0.63, 1.60) and those with classic RTT (mean change per year: 0.97; 95% CI: 0.53, 1.41). CONCLUSIONS: Findings from this study highlight the considerable burden of RTT across disease subtype and age. Despite reliance on supportive therapies and healthcare encounters, individuals with RTT experience increasing disease severity and motor-behavioral dysfunction in childhood and adolescence, underscoring the unmet needs of this population and the value of early intervention to manage RTT in the long-term.

Treatment patterns and outcomes in KRASG12C-positive advanced NSCLC patients previously treated with immune checkpoint inhibitors: A Canada-wide real-world, multi-center, retrospective cohort study.

OBJECTIVES: KRAS mutations, particularly KRASG12C, are prevalent in non-small cell lung cancer (NSCLC). Immune checkpoint inhibitors (ICIs) have been a frontline treatment, but recently developed KRASG12C-selective inhibitors, such as sotorasib, present new therapeutic options. We conducted a multi-center retrospective cohort study to gain insights into real-world treatment patterns and outcomes in patients with KRASG12C-positive advanced NSCLC receiving systemic therapy post-ICI treatment. METHODS: From the CAnadian CAncers With Rare Molecular Alterations-Basket Real-world Observational Study (CARMA-BROS), a cohort of 102 patients with KRASG12C-positive advanced NSCLC across 9 Canadian centers diagnosed between 2015 and 2021 was analyzed. Clinico-demographic and treatment data were obtained from electronic health records. Survival outcomes were assessed using Kaplan-Meier curves and Cox proportional hazards models. RESULTS: The patients (median age 66 years; 58 % female; 99 % current/former tobacco exposure; 59 % PD-L1 ≥ 50 %), exhibited heterogeneous treatment patterns post-ICI. Most patients received ICIs as a first-line therapy, with varying subsequent lines including chemotherapy and targeted therapy. In patients receiving systemic therapy post-ICI, median overall survival was 12.6 months, and real-world progression-free survival was 4.7 months. KRASG12C-selective targeted therapy post-ICI (n = 20) showed longer real-world progression-free survival compared to single-agent chemotherapy (aHR = 0.39, p = 0.012). CONCLUSION: This study contributes valuable real-world data on KRASG12C-positive advanced NSCLC post-ICI treatment. The absence of a standard treatment sequencing post-ICI underscores the need for further investigation and consensus-building in the evolving landscape of KRASG12C-targeted therapies.

Humanistic and economic burden of atopic dermatitis in pediatric patients in Spain: a systematic review.

Atopic dermatitis (AD) is a chronic, inflammatory skin disease affecting all age groups, particularly children. This systematic review provides an overview of the humanistic and economic disease burden in the pediatric population with AD in Spain. The evidence, collected from 11 observational studies published over the past 10 years, exhibits the most common characteristics of the patients, disease burden, patient-reported outcomes, use of resources, and treatment patterns. The burden of AD extends beyond physical symptoms, with associated comorbidities such as asthma and impaired health-related quality of life and mental health disorders, particularly in severe cases. Traditional therapies, primarily topical corticosteroids, face adherence and efficacy challenges. Despite promising innovative treatments and available biological therapies, their use is still limited in the pediatric population. The findings of the present review highlight the scarce scientific evidence on the economic burden of pediatric AD, as well as the most updated humanistic evidence on this disease. At the same time, the need for individualized care and innovative therapeutic interventions to address the multifaceted challenges of pediatric AD in Spain is evident.

Treatment modification patterns of glucose-lowering agents in Saudi Arabia: A retrospective real-world data analysis.

AIM: The growing number of antidiabetics has broadened therapeutic options, leading to heterogeneity in prescribing patterns. Studies identifying antidiabetics modification patterns are lacking in Saudi Arabia. Therefore, the aim of this study is to describe modification patterns in Saudi patients. METHODS: Patients ≥ 18 years old with at least one antidiabetic between 2016 and 2022 were included. Follow-up started from the earliest to the last prescription.Two modification types were evaluated: "add-on," prescribing new antidiabetics within a treatment episode, and "switching", starting a new treatment episode after the preceding ends. Descriptive statistics were used to characterize patients and estimate events proportions. RESULTS: Of 122,291 patients, 47.2 % had treatment interruption or modification, totaling 303,781 events. Interruptions accounted for 54 %, add-on for 11 %, and switching for 35 %. The median time to first event was 159 days. The most add-on included dipeptidyl peptidase-4 inhibitor (DPP-4) inhibitors to biguanide and sulfonylurea (8 %), and sulfonylurea to biguanide (8 %). Among 106,405 switching events, 23 % shifted from dual to monotherapy and 17 % from monotherapy to dual therapy. CONCLUSION: Nearly half of patients experienced modifications or interruptions, with notable shifts between monotherapies and dual therapies. These findings highlight the evolving landscape of treatment patterns in Saudi Arabia and guide future research and decision-making.

Treatment Patterns and Resource Use After Osimertinib Discontinuation in Patients with EGFR + Metastatic NSCLC.

INTRODUCTION: Current treatment guidelines for patients with epidermal growth factor receptor (EGFR)-mutated metastatic non-small cell lung cancer (mNSCLC) recommend EGFR tyrosine kinase inhibitors (TKIs) as the standard of care for first-line treatment, with third-generation osimertinib the preferred choice. However, most patients develop resistance to targeted therapy, and subsequent systemic chemotherapy is recommended. The aim of this study was to characterize the subsequent line of therapy (LOT) following osimertinib in patients with EGFR-mNSCLC. METHODS: Medical and pharmacy claims of adults who initiated a subsequent LOT (index) after initial osimertinib discontinuation between November 2015 and September 2019 were analyzed retrospectively. RESULTS: A total of 135 patients met the inclusion criteria. After metastatic diagnosis, 22.2% and 49.6% of patients were treated with osimertinib in the first and second line, respectively. After osimertinib discontinuation, most patients were treated with a platinum-based chemotherapy regimen (57%), of which 40.3% included immuno-oncology therapy. Reuse or continuation of EGFR TKIs was also common (24%). Overall, the median time to treatment discontinuation for the index LOT was 2.4 months. Proportions of patients with ≥ 1 inpatient or emergency department visit were 31.9% and 35.6%, respectively. CONCLUSIONS: The duration of the LOT following osimertinib was short and associated with tolerability issues underscoring a high unmet need for new therapies to address EGFR TKI resistance.

Burden of illness in patients with pulmonary hypertension due to interstitial lung disease: a real-world analysis.

BACKGROUND: Pulmonary hypertension due to interstitial lung disease (PH-ILD) is associated with high rates of respiratory failure and death. Healthcare resource utilization (HCRU) and cost data are needed to characterize PH-ILD disease burden. METHODS: A retrospective cohort analysis of the Truven Health MarketScan® Commercial Claims and Encounters Database and Medicare Supplemental Database between June 2015 to June 2019 was conducted. Patients with ILD were identified and indexed based on their first claim with a PH diagnosis. Patients were required to be 18 years of age on the index date and continuously enrolled for 12-months pre- and post-index. Patients were excluded for having a PH diagnosis prior to ILD diagnosis or the presence of other non-ILD, PH-associated conditions. Treatment patterns, HCRU, and healthcare costs were compared between the 12 months pre- versus 12 months post-index date. RESULTS: In total, 122 patients with PH-ILD were included (mean [SD] age, 63.7 [16.6] years; female, 64.8%). The same medication classes were most frequently used both pre- and post-index (corticosteroids: pre-index 43.4%, post-index 53.5%; calcium channel blockers: 25.4%, 36.9%; oxygen: 12.3%, 25.4%). All-cause hospitalizations increased 2-fold, with 29.5% of patients hospitalized pre-index vs. 59.0% post-index (P < 0.0001). Intensive care unit (ICU) utilization increased from 6.6 to 17.2% (P = 0.0433). Mean inpatient visits increased from 0.5 (SD, 0.9) to 1.1 (1.3) (P < 0.0001); length of stay (days) increased from 5.4 (5.9) to 7.5 (11.6) (P < 0.0001); bed days from 2.5 (6.6) to 8.0 (16.3) (P < 0.0001); ICU days from 3.8 (2.3) to 7.0 (13.2) (P = 0.0362); and outpatient visits from 24.5 (16.8) to 32.9 (21.8) (P < 0.0001). Mean (SD) total all-cause healthcare costs increased from $43,201 ($98,604) pre-index to $108,387 ($190,673) post-index (P < 0.0001); this was largely driven by hospitalizations (which increased from a mean [SD] of $13,133 [$28,752] to $63,218 [$75,639] [P < 0.0001]) and outpatient costs ($16,150 [$75,639] to $25,604 [$93,964] [P < 0.0001]). CONCLUSION: PH-ILD contributes to a high HCRU and cost burden. Timely identification, management, and treatment are needed to mitigate the clinical and economic consequences of PH-ILD development and progression.

Real-World Treatment Patterns and Timeliness of Clinical Care Pathway for Non-Small Cell Lung Cancer Patients in Austria: The PRATER Retrospective Study.

This was a retrospective study of the profile and initial treatments of adults diagnosed with early-stage (ES) non-small cell lung cancer (NSCLC) during January 2018-December 2021 at 16 leading hospital institutions in Austria, excluding patients enrolled in clinical trials. In total, 319 patients were enrolled at a planned ~1:1:1 ratio across StI:II:III. Most tested biomarkers were programmed death ligand 1 (PD-L1; 58% expressing), Kirsten rat sarcoma virus (KRAS; 22% positive), and epidermal growth factor receptor (EGFR; 18% positive). Of 115/98/106 StI/II/III patients, 82%/85%/36% underwent surgery, followed by systemic therapy in 9%/45%/47% of those [mostly chemotherapy (ChT)]. Unresected treated StIII patients received ChT + radiotherapy [43%; followed by immune checkpoint inhibitors (ICIs) in 39% of those], ICI ± ChT (35%), and ChT-alone/radiotherapy-alone (22%). Treatment was initiated a median (interquartile range) of 24 (7-39) days after histological confirmation, and 55 (38-81) days after first medical visit. Based on exploratory analyses of all patients newly diagnosed with any stage NSCLC during 2018-2021 at 14 of the sites (N = 7846), 22%/10%/25%/43% had StI/II/III/IV. The total number was not significantly different between pre-COVID-19 (2018-2019) and study-specific COVID-19 (2020-2021) periods, while StI proportion increased (21% vs. 23%; p = 0.012). Small differences were noted in treatments. In conclusion, treatments were aligned with guideline recommendations at a time which preceded the era of ICIs and targeted therapies in the (neo)adjuvant setting.

Treatment patterns for patients with BRCA1/2-positive metastatic castration-resistant prostate cancer.

BACKGROUND: Patients with BRCA-positive metastatic castration-resistant prostate cancer (mCRPC) have an aggressive disease course. This study aimed to describe real-world treatment patterns among patients with BRCA-positive mCRPC. MATERIALS AND METHODS: De-identified electronic health record data from the Flatiron Health-Foundation Medicine Inc. Metastatic Prostate Cancer Clinico-Genomic Database (January 01, 2011 to June 30, 2022) were used to select patients with BRCA-positive mCRPC initiating first-line (1L) therapy with an oncologist-defined advanced line of therapy (LOT) or androgen deprivation therapy (ADT) monotherapy. Treatment sequences and reasons for censoring were described in 1L, and among patients who initiated a second-line (2L) therapy. RESULTS: A total of 98 treated patients with BRCA-positive mCRPC were identified. The top 3 treatment regimens in 1L, overall, were ADT monotherapy (19%), enzalutamide (14%), and olaparib (13%). The main reason for censoring patients with ADT monotherapy was death (52.6%). Among 79 patients treated with an advanced LOT in 1L, 43.0% (n = 34) did not initiate a 2L therapy, of which, 29.4% died. In patients who initiated a 2L (n = 45), the most common 1L to 2L treatment sequence was olaparib to docetaxel (11.1%). The most prescribed 2L therapies were docetaxel (22.2%), olaparib (20.0%), abiraterone acetate (13.3%), and enzalutamide (11.1%). From 1L initiation, the median time-to-next-treatment was 6.2 months. CONCLUSION: Among patients with BRCA-positive mCRPC, ADT monotherapy, enzalutamide, and olaparib were most commonly used. Prognosis of BRCA-positive patients was poor, with most patients failing initial therapy resulting in a switch to a new therapy or death. These findings highlight the need for earlier and more effective treatments for patients with BRCA-positive mCRPC.

Selexipag in patients with pulmonary arterial hypertension associated with connective tissue disease (PAH-CTD): Real-world experience from EXPOSURE.

Selexipag is indicated for the treatment of pulmonary arterial hypertension (PAH), including PAH associated with connective tissue disease (CTD), and further insights into the management of selexipag-treated PAH-CTD patients in clinical settings are needed. These analyses of the ongoing, multicenter, prospective EXPOSURE (EUPAS19085) study describe characteristics, treatment patterns, tolerability, and outcomes of PAH-CTD patients initiating selexipag in Europe/Canada. All analyses were descriptive, with idiopathic PAH patients who typically display better prognosis included for context. Six hundred ninety-eight selexipag-treated patients had follow-up information; 178 (26%) had PAH-CTD. The median age was 68 years, patients were predominantly female (88%), and with WHO functional class III symptoms (63%); the median time since diagnosis was 1.7 years. There were 5% patients at low, 25% intermediate-low, 40% intermediate-high, and 30% high risk of 1-year mortality, according to the ESC/ERS 4-strata risk score. Most (80%) initiated selexipag as a triple oral therapy, and most of these (62%) remained on triple therapy 6 months post-baseline. Over a median (Q1-Q3) selexipag exposure period of 8.6 (2.5-17.2) months, 79 (44%) patients discontinued selexipag; 36 (20%) due to tolerability/adverse events. Sixty (34%) patients were hospitalized at least once; 120 hospitalizations occurred, with 49 (48%) deemed PAH-related. Survival at 1 year was 85%, and at 2 years was 71%; 29 (16%) patients died. These results describe the use of combination therapy with selexipag for patients with PAH-CTD. These findings suggest an opportunity to optimize the benefits of selexipag among patients with PAH-CTD by moving from escalating after years in response to clinical deterioration to escalating sooner to prevent clinical deterioration.
