Treatment Pattern and Outcomes in Newly Diagnosed Multiple Myeloma Patients Who Did Not Receive Autologous Stem Cell Transplantation: A Real-World Observational Study : Treatment pattern and outcomes in patients with multiple myeloma.

INTRODUCTION: The objective of this study was to describe the treatment patterns among patients with newly diagnosed multiple myeloma (MM) who had not received autologous stem cell transplantation (ASCT). It further compares the safety and clinical outcomes across different frontline regimens as well as explores whether treatment duration predicts outcomes. METHODS: Patients with MM (> 45 years) who had not received ASCT were retrospectively identified from the US SEER-Medicare (Jan 2007-Dec 2016) and Optum (Jan 2007-Sep 2018) databases. Cox proportional hazard models were used to compare overall survival (OS) among bortezomib + lenalidomide + dexamethasone regimen (VRd), lenalidomide + dexamethasone regimen (Rd), cyclophosphamide + bortezomib + dexamethasone regimen (CyBorD), bortezomib + dexamethasone regimen (Vd), and other bortezomib-containing therapies based on propensity score matching. To address immortal time bias, time-fixed and time-dependent Cox models were employed to estimate the association of longer frontline treatment exposure with outcomes. RESULTS: Mean (standard deviation; SD) age was 71 (9.8) years; and 49.51% were women. Bortezomib and lenalidomide-based combinations were the most common treatment modalities. After matching, the HR (95% CI) of OS by frontline therapies comparing VRd with Vd was 0.76 (0.66, 0.86), CyBorD was 0.87 (0.75, 1.05), for other bortezomib-based therapies was 0.56 (0.49, 0.64), Rd was 0.83 (0.73, 0.95), and for other therapies was 0.70 (0.61, 0.80). Longer frontline treatment duration was associated with better OS for overall frontline [HR (95% CI) 0.86 (0.82, 0.90)]; Vd [0.81 (0.74, 0.89)]; CyBorD [0.79 (0.64, 0.98)] and Rd [0.86 (0.78, 0.95)]. CONCLUSION: Results demonstrated that the frontline therapies prescribed to most patients who did not receive ASCT for MM in the United States were consistent with the NCCN guideline recommendations. Longer frontline treatment duration was associated with improved OS.

Impact of subsequent metastases on costs and medical resource use for prostate cancer patients initially diagnosed with localized disease.

BACKGROUND: The impact of subsequent metastases on costs and medical resource use (MRU) for prostate cancer (PC) patients initially diagnosed with localized disease was estimated. METHODS: Surveillance, Epidemiology, and End Results data, linked to Medicare (1999-2012), were used to identify 7482 patients diagnosed with subsequent metastases 12 months or more after the initial diagnosis of localized PC (cases), and they were matched to 25,709 localized PC patients without subsequent metastases (controls). Patients were followed for costs and MRU from 12 months before their index date (subsequent metastases or a matched date for controls) up to 12 months after it. Costs and MRU were stratified by the setting/type of care/service. Multivariate mixed effects regression analyses were used to construct and compare longitudinal trajectories of marginal predicted costs and predicted probabilities of MRU between cases and controls. RESULTS: Among the controls, predicted monthly costs remained relatively stable throughout the entire observation period (weighted mean per patient per month, $2746; range during 24 months, $2603-2858). In contrast, among the cases, costs increased from $2622 (95% confidence interval [CI], $2525-2719) 12 months before the diagnosis of subsequent metastases to $4767 (95% CI, $4623-4910) 1 month before the diagnosis of subsequent metastases, peaked during the month of metastases at $13,291 (95% CI, $13,148-13,435), and remained significantly higher than costs for the controls thereafter (eg, $4677 at + 12 months; 95% CI, $4549-4805). Costs and MRU increased across a wide range of settings/types, including inpatient, outpatient, home health, and hospice settings. CONCLUSIONS: In PC patients initially diagnosed with localized disease, a diagnosis of subsequent metastases is associated with substantially increased costs and MRU.

Disease and Treatment Characteristics of Men Diagnosed With Metastatic Hormone-Sensitive Prostate Cancer in Real Life: Analysis From a Commercial Claims Database.

BACKGROUND: Our understanding of the clinical characteristics and treatment patterns of men who present with newly diagnosed metastatic (M1) hormone-sensitive prostate cancer is based mainly on clinical trial data. We sought to characterize the M1 population seen in routine clinical practice using a commercial claims database. PATIENTS AND METHODS: A US claims (2000-2013) database was used to identify patients with an index diagnosis of prostate cancer. M1 patients were identified by "International Classification of Diseases, 9th revision, Clinical Modification" diagnosis codes of metastasis to bone, viscera, distant lymph node, and unspecified sites within 90 days of the prostate cancer diagnosis. Progression to castration-resistant prostate cancer was identified by exposure to ≥ 1 drugs approved for castration-resistant prostate cancer, including docetaxel, abiraterone acetate, cabazitaxel, enzalutamide, sipuleucel-T, mitoxantrone, estramustine, and radium-223. RESULTS: Among 326,907 patients with an index prostate cancer diagnosis, 9199 (2.8%) had M1 disease, including 6955 with specified metastatic disease involving the bone (77%), viscera (38%), or lymph nodes (21%). The initial treatment of M1 disease was castration in 51%, localized therapy in 16%, prostate cancer drug only in 18%, and no treatment in 15%. The median time to first castration was 33 days. CONCLUSION: The proportion of men with prostate cancer who presented with M1 disease was consistent with other observations. Only 51% of the patients were treated according to national guidelines recommending medical or surgical castration. The proportion with visceral involvement at presentation was greater than expected from the clinical trials data in the same population. Just as seen in other medical conditions, clinical trial data are not representative of real-life patients seen in routine clinical practice.

Pharmaceutical portfolio management: global disease burden and corporate performance metrics.

BACKGROUND: Biopharmaceutical companies face multiple external pressures. Shareholders demand a profitable company while governments, nongovernmental third parties, and the public at large expect a commitment to improving health in developed and, in particular, emerging economies. Current industry commercial models are inadequate for assessing opportunities in emerging economies where disease and market data are highly limited. OBJECTIVE: The purpose of this article was to define a conceptual framework and build an analytic decision-making tool to assess and enhance a company's global portfolio while balancing its business needs with broader social expectations. METHODS: Through a case-study methodology, we explore the relationship between business and social parameters associated with pharmaceutical innovation in three distinct disease areas. The global burden of disease-based theoretical framework using disability-adjusted life-years provides an overview of the burden associated with particular diseases. The social return on investment is expressed as disability-adjusted life-years averted as a result of the particular pharmaceutical innovation. Simultaneously, the business return on investment captures the research and development costs and projects revenues in terms of a profitability index. CONCLUSIONS: The proposed framework can assist companies as they strive to meet the medical needs of populations around the world for decades to come.

Diabetic peripheral neuropathy: resource utilization and burden of illness.

INTRODUCTION: Diabetic peripheral neuropathy (DPN) is a debilitating complication of diabetes and accounts for significant morbidity by pre-disposing the foot to ulceration and lower extremity amputation. Using a large US commercial claims database, this study analyzes the drug class usage and co-morbidities associated with DPN as well as estimates the associated economic burden. METHODS: Patients older than 18 and diagnosed with DPN were followed longitudinally for 2 years pre- and post-diagnosis date. Patients were analyzed for age, gender, hospital visits, ER and doctor's office visits, pharmacy claims, co-morbidities, and drug classes prescribed pre- and post-DPN diagnosis. The economic impact post-diagnosis of DPN was compared to the patients' pre-diagnosis resource use. RESULTS: In total, 10,982 incident DPN patients were identified, with a median age of 61 years, and an equal gender distribution. Post-DPN diagnosis, there was a 20% increase in the number of patients visiting hospitals and a 46% increase in the number of visits to hospitals. Further, there was a 46% increase in the annual cost per patient associated with visits to the hospitals, emergency room (ER), doctor's office, and pharmacy claims. As per the analysis presented in this study, increase in the number of visits, cost per visit, and number of patients visiting hospitals, ER and doctor's offices added up to a 46% increase in aggregated cost associated with Medical Resource Utilization (MRU) owing to DPN, with the highest increase (60%) in costs associated with hospitalization of patients with DPN. CONCLUSION: This study highlights the high economic burden associated with DPN. The results indicate that resource use significantly increases post-diagnosis of DPN, which leads to an increase in costs for payers. A noticeable proportion of patients with DPN had a pain co-diagnosis signifying the need for treatments that can effectively manage painful DPN.

Characterization of treatment resistant depression episodes in a cohort of patients from a US commercial claims database.

CONTEXT: Treatment Resistant Depression (TRD) is a significant and burdensome health concern. OBJECTIVE: To characterize, compare and understand the difference between TRD and non-TRD patients and episodes in respect of their episode duration, treatment patterns and healthcare resource utilization. DESIGN AND SETTING: Patients between 18 and 64 years with a new diagnosis of major depressive disorder (MDD) and without a previous or comorbid diagnosis of schizophrenia or bipolar disease were included from PharMetrics Integrated Database, a claims database of commercial insurers in the US. Episodes of these patients in which there were at least two distinct failed regimens involving antidepressants and antipsychotics were classified as TRD. PATIENTS: 82,742 MDD patients were included in the analysis; of these patients, 125,172 episodes were identified (47,654 of these were drug-treated episodes). MAIN OUTCOME MEASURES: Comparison between TRD and non-TRD episodes in terms of their duration, number and duration of lines of treatment, comorbidities, and medical resource utilization. RESULTS: Of the treated episodes, 6.6% (N = 3,134) met the criteria for TRD. The median time to an episode becoming TRD was approximately one year. The mean duration of a TRD episode was 1,004 days (vs. 452 days for a non-TRD episode). More than 75% of TRD episodes had at least four lines of therapy; half of the treatment regimens included a combination of drugs. Average hospitalization costs were higher for TRD than non-TRD episodes: $6,464 vs. $1,734, as were all other health care utilization costs. CONCLUSIONS: While this study was limited to relatively young and commercially covered patients, used a rigorous definition of TRD and did not analyze for cause or consequence, the results highlight high unmet medical need and burden of TRD on patients and health care resources.

Healthcare resource use in advanced prostate cancer patients treated with docetaxel.

OBJECTIVE: Although the treatment of metastatic castrate-resistant prostate cancer (mCRPC) has improved with newer therapies, there is little understanding how these therapies have impacted resource use and associated expenditures; available estimates are dated. The current study examined contemporary healthcare utilization and associated costs for mCRPC patients and how these measures changed over time. METHODS: This retrospective cohort analysis used medical and pharmaceutical insurance claims data from a large non-payer-owned integrated claims database of US commercial insurers. Amongst all patients with a prostate cancer diagnosis (n=256,464), those with ≥ 1 docetaxel claim (docetaxel cohort, n=3642) were identified as mCRPC patients. Within the docetaxel cohort, an additional 6-months follow-up cohort (n=2862) was identified, i.e., patients with at least 6 months of follow-up after the first docetaxel claim. Resource utilization and costs were identified for all-cause hospitalizations, emergency room (ER) visits, physician visits and ambulatory visits, and prostate cancer-related prescription treatments. RESULTS: Significant increases in the mean per-patient-per-month (PPPM) count for the docetaxel cohort were observed for all medical resources measured (hospitalizations and ER, physician, and ambulatory visits) in the post-docetaxel period compared with the pre-docetaxel period (p<0.0001); similar significant increases were observed for the 6-months follow-up cohort in the last 6 months (prior to lost to follow-up date) compared with the period preceding the last 6 months (p<0.0408 ambulatory visits, p<0.0001 all other resources). Total docetaxel cohort costs (mean [standard deviation]) rose from an average PPPM cost of US$2593 (3208) in the pre-docetaxel period to US$5847 (6990) in the post-docetaxel period (p<0.0001); each of the individual resources measured (hospitalization, all healthcare visits, and prescription costs) demonstrated significant increases (p<0.0001). LIMITATIONS: Retrospective study design. CONCLUSIONS: This large database analysis showed a significant increase in use of healthcare resources and associated costs among mCRPC patients following first-line docetaxel treatment.

The burden of chronic low back pain with and without a neuropathic component: a healthcare resource use and cost analysis.

BACKGROUND: This research addresses the need for population-based studies on the burden of chronic low back pain (CLBP) by examining healthcare service use and costs for patients with and without neuropathic components in the US population. METHODS: Data were analyzed from PharMetrics IMS LifeLink™ US Claims Database (2006-2008). Patients (≥18 years) with 36 months continuous enrollment, ICD-9 code for low back pain, and claims in 3 out of 4 consecutive months in the 12-month prospective period were included and classified with CLBP. Patients were further classified with a neuropathic component (wNP) and without a neuropathic component (woNP) based on ICD-9 codes. Healthcare resources, physical therapy, prescription medication use, and associated costs were assessed for the period January 1-December 31, 2008. RESULTS: A number of patients (39,425) were identified with CLBP (90.4% wNP). Patients wNP included more women, were older and more likely to have clinically diagnosed depression, and made significantly greater use of any prescription medication at index event, opioids (particularly schedule II), and healthcare resources. Total direct costs of CLBP-related resource use were ∼US$96 million over a 12-month follow-up. CLBP wNP accounted for 96% of total costs and mean annual cost of care/patient was ∼160% higher than CLBP patients woNP (US$ 2577 vs US$ 1007, p < 0.0001). LIMITATIONS: This study was descriptive and was not designed to demonstrate causality between diagnosis, treatment, and outcomes. Resource use and costs for reasons other than LBP were not included. Patients with neuropathic pain are more likely to seek treatment; therefore CLBP patients with a non-neuropathic component may be under-represented. CONCLUSIONS: The disproportionately high share of interventional resource use in CLBP wNP suggests greater need for new treatment options that more comprehensively manage the range of pain symptoms and signaling mechanisms involved, to help improve patient outcomes and reduce the burden on healthcare systems.
