Adherence to First-Line Intravesical Bacillus Calmette-Guérin Therapy in the Context of Guideline Recommendations for US Patients With High-Risk Non-muscle Invasive Bladder Cancer.

Bacillus Calmette-Guérin (BCG) can reduce recurrence and delay progression among patients with high-risk non-muscle invasive bladder cancer (NMIBC), but is associated with a substantial emotional, physical, and social burden. This study evaluated the adequacy of first-line intravesical BCG treatment among high-risk NMIBC patients in the United States, including the subgroup with carcinoma in situ (CIS) of the bladder. Adults with high-risk NMIBC treated with BCG were selected from de-identified MarketScan® Commercial, Medicare, and Medicaid Databases (1/1/2010-2/28/2021).

Healthcare Resource Utilization and Costs in Patients with EGFR-Mutated Advanced Non-Small Cell Lung Cancer Receiving First-Line Treatment in the United States: An Insurance Claims-Based Descriptive Analysis.

Background: An estimated 10-15% of non-small cell lung cancer (NSCLC) cases present with epidermal growth factor receptor mutation (EGFRm). While EGFR tyrosine kinase inhibitors (EGFR-TKIs) such as osimertinib have become first-line (1L) standard of care for these patients, limited chemotherapy use still occurs in real-world practice. Studies of healthcare resource use (HRU) and cost of care provide a means by which the value of various treatment regimens, healthcare efficiency, and disease burden can be assessed.

Healthcare resource utilization and costs associated with inflammatory bowel disease among patients with chronic inflammatory diseases: a retrospective cohort study.

Background: Chronic inflammatory diseases (CIDs; ankylosing spondylitis [AS], psoriatic arthritis [PsA], psoriasis [PsO], or rheumatoid arthritis [RA]) and inflammatory bowel disease (IBD; Crohn's disease and ulcerative colitis) are associated with substantial economic burden. The relative increased costs among patients with CIDs and concomitant IBD compared to those without IBD is an important consideration when deciding on the clinical management of patient symptoms. Given the increasing use of novel agents for the treatment of CIDs, including those that may increase the risk of IBD in patients with CIDs, the objective of the study was to describe the incidence of IBD and to quantify healthcare resource utilization (HRU) and costs associated with IBD among patients with CIDs.

Real-world incidence of inflammatory bowel disease among patients with other chronic inflammatory diseases treated with interleukin-17a or phosphodiesterase 4 inhibitors.

(1) To assess the real-world incidence of inflammatory bowel disease (IBD) in patients with or without other chronic inflammatory diseases (CIDs), and (2) to understand whether IBD incidence differs in CID patients receiving interleukin-17a signaling antagonists (anti-IL-17a) or phosphodiesterase 4 inhibitors (PDE4i) versus patients using a biologic not indicated for IBD or biologic-naïve patients. The MarketScan Research Databases (January 2010-July 2017) were used. A CID population was created from patients with ankylosing spondylitis, psoriatic arthritis, psoriasis or rheumatoid arthritis (RA).

Comparative analysis of US real-world dosing patterns and direct infusion-related costs for matched cohorts of rheumatoid arthritis patients treated with infliximab or intravenous golimumab.

Purpose: The objectives of this study were to evaluate and compare treatment patterns and infusion-related health care resource expenditures for rheumatoid arthritis (RA) patients initiating golimumab for intravenous use (GLM-IV) and infliximab (IFX) therapy and to assess cost implications from the commercial perspective.

Methods: Adult RA patients with a new episode of GLM-IV or IFX treatment between Janu-ary 1, 2014 and March 31, 2016 were identified from MarketScan databases and evaluated for maintenance infusion intervals and related costs of treatment. IFX and GLM-IV patients were matched 1:1 on index medication treatment duration, gender, payer type, prior biologic use, and post-index methotrexate use.

Analysis of real-world treatment patterns in a matched rheumatology population that continued innovator infliximab therapy or switched to biosimilar infliximab.

Purpose: This study compared treatment patterns of Turkish patients with a diagnosis of rheumatoid arthritis (RA) who were treated with innovator Remicade (infliximab [IFX]) and either continued IFX or switched to CT-P13.

Materials And Methods: Adult RA patients with ≥1 IFX claim were identified from the Turkish Ministry of Health database. Eligible patients initiated and continued IFX treatment (continuers cohort [CC]) or initiated IFX and switched to CT-P13 (switchers cohort [SC]) during the study period.

A descriptive analysis of real-world treatment patterns of innovator (Remicade) and biosimilar infliximab in an infliximab-naïve Turkish population.

Purpose: Biosimilar IFX (CT-P13) received marketing approval in Turkey for treatment of rheumatologic diseases, including ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis. Population data on real-world treatment patterns of CT-P13 following marketing approval in European countries are largely unreported. This study examined the prescribing and medication utilization patterns of innovator infliximab (IFX) and CT-P13 in Turkey for patients with RA or IBD naïve to either IFX.

A real-world, multi-site, observational study of infusion time and treatment satisfaction with rheumatoid arthritis patients treated with intravenous golimumab or infliximab.

Objectives: To assess real-world infusion times for golimumab (GLM-IV) and infliximab (IFX) for rheumatoid arthritis (RA) patients and factors associated with treatment satisfaction.

Methods: An observational study assessed infusion time including: clinic visit duration, RA medication preparation and infusion time, and infusion process time. Satisfaction was assessed by a modified Treatment Satisfaction Questionnaire for Medication (patient) and study-specific questionnaires (patient and clinic personnel).

Satisfaction with Subcutaneous Golimumab and its Auto-Injector among Rheumatoid Arthritis Patients with Inadequate Response to Adalimumab or Etanercept.

Background: Patient perceptions of treatment success, including satisfaction/preference, may complement clinical efficacy assessments.

Objective: Our objective was to evaluate satisfaction with subcutaneous golimumab and its auto-injector in patients with rheumatoid arthritis (RA) and an inadequate adalimumab/etanercept response.

Methods: In the multicenter, assessor-blinded GO-SAVE study, 433 patients with active RA (28-joint Disease Activity Score incorporating erythrocyte sedimentation rate [DAS28-ESR] ≥ 3.

Medication Adherence, Treatment Patterns, and Dose Reduction in Patients with Metastatic Castration-Resistant Prostate Cancer Receiving Abiraterone Acetate or Enzalutamide.

Background: The efficacy of and overall survival associated with metastatic castration-resistant prostate cancer (CRPC) treatments rely on patients' consistent adherence to the recommended dosage regimens.

Objectives: To evaluate treatment patterns and patient adherence to abiraterone acetate or enzalutamide therapy in real-world practice, and to examine the factors that may be associated with medication dose reduction in patients with metastatic CRPC.

Methods: Retrospective analyses were conducted using the Truven Health MarketScan research databases among patients with metastatic CRPC who initiated treatment with abiraterone acetate or enzalutamide between October 1, 2012, and December 31, 2014 (index date).

Assessment of Real-World Central Nervous System Events in Patients with Advanced Prostate Cancer Using Abiraterone Acetate, Bicalutamide, Enzalutamide, or Chemotherapy.

Background: Central nervous system (CNS) events are frequently reported among patients with advanced prostate cancer as a consequence of the treatments used in this patient population.

Objective: To assess the incidence of CNS events in patients with advanced prostate cancer who initiated treatment with abiraterone acetate, bicalutamide, enzalutamide, or chemotherapy.

Methods: The Truven Health MarketScan Research databases were used to retrospectively identify patients with prostate cancer who initiated treatment with abiraterone acetate, enzalutamide, bicalutamide, or chemotherapy after September 1, 2012 (ie, the index date).

Assessment of Evidence-Based Standards in the Treatment of Advanced Prostate Cancer in a Community Practice.

Introduction: Although the monitoring of patients with advanced prostate cancer is essential to optimize treatment, little is known about adherence to guidelines. In this study we compared testing practices at an integrated urology/radiation oncology group practice with evidence-based guidelines and best practices.

Methods: Electronic medical records up to December 2014 from the integrated urology/radiation oncology group practice were queried to identify patients who received androgen deprivation therapy and in whom advanced disease was staged as androgen deprivation therapy sensitive, subcastration resistant (incompletely defined probable castration resistant prostate cancer) or castration resistant after April 2011 and for 6 months or more.

Duration of Treatment in Prostate Cancer Patients Treated with Abiraterone Acetate or Enzalutamide.

Background: Abiraterone acetate (AA) and enzalutamide (ENZ) are oral therapies offering survival benefit to metastatic castration-resistant prostate cancer (mCRPC) patients. Despite the availability of multiple treatment options for mCRPC, there is a lack of information on the effect that being initiated on AA or ENZ has on the combined prostate cancer treatment duration.

Objective: To compare the combined duration of prostate cancer treatments of patients initiated on AA with that of patients initiated on ENZ.

Cost per median overall survival month associated with abiraterone acetate and enzalutamide for treatment of patients with metastatic castration-resistant prostate cancer.

Objective: To calculate costs per median overall survival (OS) month in chemotherapy-naïve patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone acetate plus prednisone (AA + P) or enzalutamide.

Methods: Median treatment duration and median OS data from published Phase 3 clinical trials and prescribing information were used to calculate costs per median OS month based on wholesale acquisition costs (WACs) for patients with mCRPC treated with AA + P or enzalutamide. Sensitivity analyses were performed to understand how variations in treatment duration and treatment-related monitoring recommendations influenced cost per median OS month.

Treatment Sequences and Pharmacy Costs of 2 New Therapies for Metastatic Castration-Resistant Prostate Cancer.

Background: The approval of new therapies for metastatic castration-resistant prostate cancer (mCRPC), including the oral agents abiraterone acetate and enzalutamide, has altered the standard of care for patients with mCRPC. Little information exists regarding the sequences in which new therapies for mCRPC with evidence of survival benefits are used.

Objective: To describe the sequence of medication use for patients with mCRPC as observed in 3 healthcare data sets.

Quality process measures for rheumatoid arthritis: performance from members enrolled in a national health plan.

Background: Health care quality problems are reflected in the underuse, overuse, and misuse of health care services. There is evidence suggesting that the quality of rheumatoid arthritis (RA) patient care is suboptimal, which has spurred the development of a number of systematic quality improvement metrics.

Objective: To investigate a quality process measurement set in a sample of commercially insured RA patients.
