Real-World Outcomes of Trilaciclib Among Patients with Extensive-Stage Small Cell Lung Cancer Receiving Chemotherapy.

INTRODUCTION: Trilaciclib was recently approved in the USA for reducing chemotherapy-induced myelosuppression (CIM) among adults with extensive-stage small cell lung cancer (ES-SCLC) when administered prior to chemotherapy. There is limited understanding of real-world outcomes of trilaciclib. METHODS: A comprehensive literature review was conducted using a keyword search in the MEDLINE, Embase, and conference abstracts. Additional studies were identified through communications with the authors of relevant studies. Published and unpublished real-world studies of trilaciclib- and comparable non-trilaciclib-treated patients with ES-SCLC were included. Evidence on myelosuppressive hematologic adverse events (HAEs), cytopenia-related healthcare utilization, and other reported outcomes (e.g., hospitalizations, dose reduction, and treatment delay) were synthesized. If feasible, outcomes were compared qualitatively between the trilaciclib and historical reference groups, and between first-line trilaciclib initiators and the overall trilaciclib population. Weighted averages were estimated for selected outcomes using sample size as the weight. RESULTS: The literature search identified five unique studies based on eight records-two included trilaciclib only, two non-trilaciclib only, and one both. In trilaciclib cohorts, the weighted average prevalence of grade ≥ 3 myelosuppressive HAEs in ≥ 1 lineage, ≥ 2 lineages, and all three lineages was 40.5%, 14.5%, and 7.5%, respectively. All rates were numerically lower compared to the historical non-trilaciclib cohorts (58.8%, 28.0%, 13.0% respectively). Cytopenia-related healthcare utilization was also lower in the trilaciclib cohorts. In general, first-line trilaciclib initiators had numerically lower myelosuppressive HAEs and cytopenia-related healthcare utilization than the overall trilaciclib patients. CONCLUSIONS: The existing evidence suggests that trilaciclib may reduce single and multilineage grade ≥ 3 myelosuppressive HAEs and cytopenia-related healthcare utilization among patients with ES-SCLC in the real world. It is a promising new treatment for CIM prevention in ES-SCLC and may bring greater benefits to first-line trilaciclib initiators. Future studies are recommended to further evaluate the real-world effectiveness of trilaciclib.

Burden of chemotherapy-induced myelosuppression among patients with extensive-stage small cell lung cancer: A retrospective study from community oncology practices.

BACKGROUND: Myelosuppression is a major dose-limiting complication of chemotherapy for patients with extensive-stage small cell lung cancer (ES-SCLC). The objective was to describe the burden of myelosuppression, treatment patterns, and supportive care use among patients with ES-SCLC treated with chemotherapy in a US community oncology setting. METHODS: This retrospective cohort study used structured electronic medical record (EMR) data from the Florida Cancer Specialists & Research Institute between January 2013 and December 2020. Adult patients with ES-SCLC who were treated with chemotherapy between September 2013 and November 2020 were identified. The index date was the date of the first chemotherapy-containing line of therapy (LOT). Patients were followed for a minimum of 30 days after index (unless patient died) until December 31, 2020, or end of activity in the EMR data, whichever occurred first. Incidence and frequency of myelosuppressive episodes/events, treatment patterns, eligibility for red blood cell (RBC) or platelet transfusions, and supportive care use (granulocyte colony-stimulating factor [G-CSF], erythropoiesis-stimulating agents [ESAs], intravenous [IV] hydration) during the follow-up period were reported. RESULTS: The study population included 1239 patients. Most (94.0%) patients started first-line chemotherapy at index. During follow-up and across all chemotherapy-containing LOTs, 1222 (98.6%) patients had at least 1 myelosuppressive episode; 62.1% of patients had grade ≥ 3 myelosuppressive episodes in at least one lineage, 33.9% had grade ≥ 3 myelosuppressive episodes in at least two lineages, and 15.5% had grade ≥ 3 myelosuppressive episodes in all three lineages. Supportive care use included 89.7% of patients who received G-CSF, 24.4% who received ESAs, and 52.1% who received IV volume expansion. Almost one-third (32.6%) of patients were eligible to receive RBC transfusions based on lab values (hemoglobin < 8 g/dL). CONCLUSION: There is a high burden related to multilineage myelosuppression among chemotherapy-treated patients with ES-SCLC in the community oncology setting. Reducing myelosuppression could make chemotherapy treatment safer, reduce the need for supportive care, and potentially prevent the treatment of complications.

Real-world treatment utilization and economic implications of lupus nephritis disease activity in the United States.

BACKGROUND: Lupus nephritis (LN) is a common and severe complication of systemic lupus erythematosus (SLE), with approximately 40% of patients with SLE developing LN. Even with treatment, 10%-30% of patients will progress to end-stage renal disease (ESRD). Although many studies have assessed the clinical value of low disease activity in LN, the economic implications are less defined. OBJECTIVE: To evaluate treatment utilization and health care costs associated with active disease, low disease activity, and ESRD in patients with LN. METHODS: A retrospective analysis of Optum pharmacy and medical claims data from 2015 to 2019 was performed and included patients with a diagnosis of SLE (International Classification of Diseases, Ninth Revision or Tenth Revision codes 710.0 or M32, respectively) and additional prespecified criteria for LN. Total health care payer costs for medical and pharmacy services and treatment utilization for commonly prescribed medications were determined for periods of low disease activity, active disease, or ESRD. RESULTS: A total of 21,251 patients (mean age 60.3 years; 87% female; 55% White patients and 18% Black patients) with a mean follow-up period of 30.6 months were included; the majority of patients had active disease (67.3%), followed by low disease activity (51.3%), and ESRD (10.5%). Glucocorticoids were used 2 times more often and mycophenolate mofetil was used 4 times more often in patients with active disease vs low disease activity. Glucocorticoids, mycophenolate mofetil, and tacrolimus were more commonly used in patients with ESRD vs those with low disease activity. Mean medical costs were $4,777 per month in active disease and $18,084 per month in ESRD vs $2,523 per month in low disease activity. CONCLUSIONS: Treatment burden and costs are high for patients with active disease and ESRD in LN. Treatments that allow patients to achieve and maintain low disease activity may help improve patient outcomes and reduce medication use and overall health care costs.

Economic Impact of Transformation to Acute Myeloid Leukemia Among Actively Managed Patients with Higher-Risk Myelodysplastic Syndromes in the United States.

INTRODUCTION: Transformation of higher-risk myelodysplastic syndromes (MDS) to acute myeloid leukemia (AML) may be associated with increased healthcare resource utilization (HCRU) and costs. To describe this economic impact, HCRU and costs were compared between US patients who experienced transformation to AML and those who did not. METHODS: Using the Optum administrative claims data, this retrospective matched cohort study identified patients (≥ 18 years old) with higher-risk MDS who initiated first-line therapy between January 1, 2008, and June 30, 2019. Patients whose disease transformed to AML were matched 1:1 to patients whose disease did not transform, based on the duration of follow-up. The follow-up period was divided into two periods: pre- (before transformation to AML) and post-AML (after transformation to AML). For patients who did not transform to AML, pre- and post-AML periods were determined using the transformation date of their matched pair. HCRU and total adjusted costs (2019 US dollars, $) were compared between patients who transformed to AML and those who did not. RESULTS: A total of 118 matched patient pairs were included in the study. The hospitalization rate was significantly higher in patients who transformed than in those who did not during the entire follow-up (58.8% vs. 44.1%; P = 0.0295) and post-AML (47.5% vs. 28.0%; P = 0.0028) periods. Across all periods, supportive care use was significantly higher among patients who transformed to AML vs. patients who did not transform. Adjusted mean monthly costs for patients with higher-risk MDS who transformed to AML were higher than those who did not transform ($25,964 vs. $19,150; P < 0.0001). The observed total cost difference was more notable in the post-AML period ($36,424 vs. $14,860; P < 0.0001). CONCLUSIONS: Patients with higher-risk MDS whose disease transformed to AML incurred significantly higher healthcare costs compared to those whose disease did not transform, highlighting the important need for treatments that prevent or delay transformation.

Duration of frontline therapy and impact on clinical outcomes in newly diagnosed multiple myeloma patients not receiving frontline stem cell transplant.

BACKGROUND: Extended first-line therapy (1LT) has improved clinical outcomes in newly diagnosed multiple myeloma (NDMM). This retrospective study of NDMM patients evaluated the relationship between dose-attenuation of 1LT and duration of therapy (DOT) and DOT on outcomes. METHODS: Adults with NDMM not undergoing stem cell transplant (SCT) from January 1, 2012 toMarch 31, 2018 from the Integrated Oncology Network were included; 300 were randomly selected for chart review. 1LT DOT, time to next treatment (TTNT), progression-free survival (PFS), and overall survival (OS) were estimated using Kaplan-Meier analysis. Marginal structural models evaluated relationships between DOT and TTNT, PFS, and OS at 2 years accounting for confounders and survival bias from the time-dependent nature of DOT. RESULTS: Of 300 chart-reviewed patients, 93 were excluded for incomplete data or meeting exclusion criteria. Among 207 NDMM patients, median age was 74 years; 146 (70.5%) did not receive dose-attenuation during 1LT. Patients with short DOT were older, frailer, with a higher comorbidity burden, and a significantly lower proportion had an Eastern Cooperative Oncology Group PS = 0. As DOT increased, more patients underwent dose-attenuation (p < 0.0001). The median 1LT DOT was 20.9 (95% confidence interval [CI]: 13.9, 26.4) versus 4.2 months (95% CI: 3.2, 4.9) for patients receiving versus not receiving dose-attenuation, respectively (p < 0.0001). After accounting for survival bias, confounder-adjusted TTNT was prolonged with each additional month of 1LT (odds ratio [OR]: 0.76 [95% CI: 0.75, 0.78]); likelihoods of risks of disease progression (OR: 0.87 [95% CI: 0.86, 0.88]) and death at 2 years (OR: 0.72 [95% CI: 0.70, 0.74]) were reduced with each month of 1LT (p < 0.0001 for all outcomes). CONCLUSIONS: Dose-attenuated 1LT was associated with longer DOT among patients with non-SCT NDMM. Each additional month of 1LT was associated with a reduced adjusted likelihood of disease progression and death at 2 years. Dose-attenuation of 1LT can extend DOT; longer DOT may improve clinical outcomes.

Health Care Resource Utilization and Costs for Metastatic Breast Cancer Patients Newly Treated with Human Epidermal Growth Factor Receptor 2 (HER2)-Targeted Agents.

INTRODUCTION: HER2-positive metastatic breast cancer (mBC) is an incurable disease associated with years of chronic therapy and excess cost. HER2-targeted therapies have shown survival benefit for early-stage and mBC; however, the economic impact of these therapies has not been fully assessed. We evaluated health care resource use (HCRU) and costs of mBC patients treated with HER2-targeted therapy. METHODS: This was a retrospective cohort study using the IQVIA Real-World Data Adjudicated Claims Database (July 1, 2014 to July 31, 2019). Female patients aged ≥18 years with mBC who initiated HER2-targeted therapy in the prior year were identified. The index date was the initiation date of the HER2-targeted agent, after which patients were required to have ≥12 months of follow-up. Annual and cumulative all-cause and BC-related costs (2019 USD) and annual BC-related HCRU were computed in years 1, 2, and 3 following the index date. RESULTS: Following the initiation of HER2-targeted therapy, the mean annual total all-cause costs per patient in years 1 (n = 423), 2 (n = 357), and 3 (n = 166) were $320,892 (SD: $224,343), $235,159 (SD: $185,287), and $226,254 (SD: $197,901), respectively. The mean annual total BC-related costs were $240,048 (SD: $151,230), $175,631 (SD: $148,058), and $165,506 (SD: $159,374) in years 1, 2, and 3, respectively. A major portion of BC-related costs were costs associated with HER2-targeted treatment. The 3-year cumulative all-cause and BC-related total costs were $769,573 (SD: $456,920) and $624,455 (SD: $401,319), respectively. CONCLUSION: Treatment of HER2-positive mBC is a substantial economic burden. A potential approach to minimizing cost and HCRU is to prevent recurrence.

Clinical impact of transformation to acute myeloid leukemia in patients with higher-risk myelodysplastic syndromes.

Aim: Forty percent of patients with higher-risk myelodysplastic syndromes (HR-MDS) transform to acute myeloid leukemia (AML). Materials & methods: This retrospective study assessed the impact of HR-MDS transformation to AML on OS in a 6-month landmark analysis and the results were validated using a time-varying analysis. Results: The rate of AML transformation was 26.9% at 1 year. Patients who transformed to AML had a higher risk of death than patients who did not in the 6-month landmark analysis (HR: 1.82; p: 0.0072) and time-varying analysis at 1 year (HR: 2.85; p < 0.0001). Patients treated with azacitidine and decitabine in first-line therapy had similar results. Conclusion: HR-MDS transformation to AML is associated with inferior OS in patients with HR-MDS initiating first-line therapy.

Up to 40% of patients with higher-risk myelodysplastic syndromes (HR-MDS) could experience deterioration or progression to acute myeloid leukemia (AML), a type of blood cancer. We conducted a study to assess whether HR-MDS progression to AML had an unfavorable impact on patient life expectancy after initiating treatment for HR-MDS. Our study concluded that patients who experienced progression to AML had a higher chance of dying immediately after their progression to AML than patients who did not. Patients who received azacitidine and decitabine as their first treatment for HR-MDS had similar results.

Characteristics and Treatment Patterns of Newly Diagnosed Open-Angle Glaucoma Patients in the United States: An Administrative Database Analysis.

PURPOSE: To characterize newly diagnosed primary open-angle glaucoma (OAG) patients and to describe their treatment journey in United States clinical practice according to the use of topical therapy, laser trabeculoplasty, and surgical procedures. DESIGN: Retrospective claims database study. PARTICIPANTS: Patients with at least 2 diagnoses of OAG 7 days or more apart and within 1 year, with the first (index) diagnosis in 2010, at least 30 months of continuous enrollment before index diagnosis with no OAG diagnosis or medication (exception for ocular hypertension diagnosis), and 48 months of continuous enrollment. METHODS: Analysis of United States healthcare insurance claims database (July 2007-December 2014). MAIN OUTCOME MEASURES: Treatment patterns and ophthalmology visits were evaluated over 48 months in 4 cohorts based on initial therapy after the index diagnosis: (1) drug monotherapy, (2) combination drug therapy, (3) glaucoma procedure, or (4) no claims for treatment. Treatment modification was defined as an addition to or change in drug therapy or procedure. RESULTS: In total, 83.0% of patients (5120/6172) began a drug therapy (69.5%) or underwent a procedure initially (13.5%); topical prostaglandin analogs (n = 2887/5120 [56.4%]) and laser trabeculoplasty (n = 705/5120 [13.8%]) were the most common. During the 4-year follow-up, 58.3% of patients (2109/3620) who began drug monotherapy experienced no further treatment modification. Over this period, 43.8% of patients who began treatment (2242/5120) experienced a treatment modification to the first treatment. Two thirds (1505/2242 [67.1%]) of these patients subsequently underwent a third treatment modification. Ophthalmology visits declined over time regardless of initial therapy, with the greatest decrease among the untreated and first-treatment procedure cohorts. CONCLUSIONS: The high rates of 2 or 3 treatment modifications over the 4-year period suggest an unmet need for glaucoma therapies with durable and predictable actions.

Treatment approaches for older and oldest patients with diffuse large B-cell lymphoma - Use of non-R-CHOP alternative therapies and impact of comorbidities on treatment choices and outcome: A Humedica database retrospective cohort analysis, 2007-2015.

INTRODUCTION: We characterized real-world treatment patterns in older (65-74 years) and oldest (75-85 years) patients with diffuse large B-cell lymphoma (DLBCL) receiving initial therapy (R-CHOP, non-R-CHOP regimens). Impact of comorbidities on treatment choice, and overall and progression-free survival (OS, PFS) were assessed by age. PATIENTS AND METHODS: Using the Humedica database, we identified 1436 newly diagnosed patients with DLBCL who received frontline therapy from 1/07-9/15. The 885 patients ≥65 years of age were further evaluated for baseline demographics, comorbidities, initial therapy, and PFS/OS. RESULTS: Of 885 patients, 406 (45.9%) were age 65-74, and 479 (54.1%) age 75-85, years. First line therapy was R-CHOP (61.8%) or non-R-CHOP (38.2%). Although Charlson Comorbidity Index (CCI) scores were similar at baseline, congestive heart failure and myocardial infarction were more common in those receiving non-R-CHOP regimens. Survival outcomes were superior for those receiving initial R-CHOP, versus non-R-CHOP, therapy (median PFS 53.9 versus 27.8 months; two-year PFS 71.2% versus 51.6%, p < .0001; median OS not reached versus 45 months; two-year OS 81.3% versus 62.9%, p < .0001, respectively). Only 10.4% (R-CHOP) and 12.1% (non-R-CHOP) of patients received second line therapies. Two-year OS by age (65-74, 75-85 years) was 66.4% and 39.1%, respectively with R-CHOP (p = .0045), and 74.3% and 54.5%, respectively with non-R-CHOP (p = .004), therapy. Age ≥ 75 years and CCI of 2+ were associated with shorter OS and PFS. CONCLUSIONS: This study identified real-world first line treatment patterns for older patients with DLBCL. Our findings support the feasibility of administering standard R-CHOP therapy, even to oldest patients with DLBCL.

Six-Month Use of Droxidopa for Neurogenic Orthostatic Hypotension.

BACKGROUND: Droxidopa is approved for adult patients with symptomatic neurogenic orthostatic hypotension (nOH); there is limited information regarding effects on symptoms, outcomes, and quality of life (QOL) beyond two weeks of treatment. OBJECTIVE: Examine the real-world experience of patients taking droxidopa after six months of treatment. METHODS: This non-interventional, US-based, prospective cohort study utilized a pharmacy hub, identifying patients who recently started droxidopa for nOH treatment. Questionnaires for fall frequency and other patient-reported outcomes (PROs) were completed at baseline and one, three, and six months following droxidopa initiation. RESULTS: 179 enrolled patients completed baseline surveys. Droxidopa continuation rates were high at months one, three, and six (87%, 79%, and 75%, respectively). From baseline to month one, there was significant reduction in the proportion of patients reporting falling at least once (54.1% vs. 43.0%; P = 0.0039), with similar observations at month three (52.9% vs. 44.5%; P = 0.0588) and month six (51.4% vs. 40.0%; P = 0.0339). Significant improvements from baseline to month one were observed and maintained at months three and six for most PROs, including the Orthostatic Hypotension Symptom Assessment Item 1, Short Falls Efficacy Scale-International, Sheehan Disability Scale, Physical Component of the 8-item Short-Form Health Survey, and Patient Health Questionnaire-9. CONCLUSIONS: In this non-interventional prospective study, fewer nOH patients reported falling after one, three, and six months of droxidopa treatment. Further, improvements reported in nOH symptoms, physical function, and QOL measures were maintained for six months following treatment initiation. Results from randomized clinical trials are required to validate the findings.

Evaluation of treatment patterns and survival among patients with diffuse large B-cell lymphoma in the USA.

AIM: To evaluate treatment patterns of diffuse large B-cell lymphoma (DLBCL). PATIENTS & METHODS: First-line and relapsed/refractory treatment patterns and survival outcomes following first-line therapy in adult patients newly diagnosed with DLBCL were evaluated. RESULTS: A total of 1436 DLBCL patients initiated treatment and mainly received a combination regimen versus monotherapy (92.1 vs 7.9%). Patients who received monotherapy were older with more comorbidities and had shorter progression-free survival than patients receiving combination therapy (median: 31.3 vs 55.8 months). In the second-line setting (n = 164), rituximab-based combination regimens were most common; 25% underwent stem cell transplantation, and were younger with fewer comorbidities. CONCLUSION: These results illustrate the need for new treatment options for patients unable to tolerate initial combination therapy and transplant-ineligible patients who require salvage therapy.

A retrospective study evaluating treatment patterns and survival outcomes in elderly patients with acute myeloid leukemia treated in the United States with either 7+3 or a hypomethylating agent.

Intensive treatment for newly diagnosed acute myelogenous leukemia (ND-AML) patients are reserved for "fit" patients. While guidelines recommend evaluation of age, performance status and comorbidities, there is no consensus on the definition of "fitness" or optimal therapy for elderly AML patients. This retrospective study evaluated characteristics and survival outcomes of 274 patients (age ≥60 years) with ND-AML treated with 7 + 3 (cytarabine + an anthracycline) vs. hypomethylating agents (HMAs). Most patients received 7 + 3 (60.2%) vs. HMAs (39.8%) in first-line therapy (1 L T); more HMA patients were ≥75 years old and had more comorbidities. Median progression-free survival (PFS) following 1 L T was longer for patients who received 7 + 3 vs. HMAs (6.7 months [95% confidence interval (CI)]: 4.9, 11.1) vs. 4.1 months (95% CI: 2.8, 4.9, respectively). Median overall survival (OS) following 1 L T was also longer for patients who received 7 + 3 vs. HMAs (14.7 months [95% CI: 11.0, not estimated] vs. 4.3 months [95% CI: 3.2, 5.8], respectively). An age-adjusted Charlson Comorbidity Index score of ≥4 vs. < 4 negatively affected PFS and OS irrespective of treatment. Overall, choosing an HMA over 7 + 3 in elderly patients with ND-AML may be influenced by age and comorbidities; patients receiving 7 + 3 had longer survival than those on an HMA.

Treatment Patterns and Survival Outcomes in Patients With Follicular Lymphoma: A 2007 to 2015 Humedica Database Study.

BACKGROUND: Few studies have evaluated real-world treatment patterns and survival in follicular lymphoma (FL). This study evaluated these outcomes among newly diagnosed patients with FL in routine clinical care. PATIENTS AND METHODS: A retrospective study was conducted in newly diagnosed patients with FL from Humedica, a large United States electronic medical record database, from January 1, 2008 to July 31, 2015. Patients were followed from treatment initiation until death, loss to follow-up, or end of study (September 30, 2015). Treatment patterns were assessed in the follow-up period. Progression-free survival (PFS) and overall survival (OS) at 2 years were evaluated in the overall population using Kaplan-Meier analyses. OS was also compared between patients with and without evidence of disease progression within 2 years following first-line therapy (ie, early progressors vs. non-early progressors). RESULTS: A total of 1346 patients were included in the study, with most patients receiving rituximab-based regimens. Fewer early progressors received rituximab-based regimens. Across all lines, combination therapies predominated, particularly bendamustine + rituximab. Following first-line therapy, OS was 86.9% at 2 years, and median OS was not reached. Two-year PFS after first-line therapy was 64.6%, and median PFS was 48.1 months (95% confidence interval, 39.4-58.4 months). OS at 2 years was 76.8% among early progressors versus 90.4% among non-early progressors (P < .001); the median OS was not reached in both groups. CONCLUSION: In routine clinical practice, rituximab-based regimens predominated; however, utilization of these regimens differed among early and non-early progressors. The assessment of survival outcomes also highlights the negative impact of early progression on OS in the rituximab-era.

Transfusion-free interval is associated with improved survival in patients with higher-risk myelodysplastic syndromes engaged in routine care.

Most higher-risk myelodysplastic syndrome (HR-MDS) patients will become transfusion-dependent, leading to potential complications, including infections or end-organ dysfunction. Data correlating achievement of transfusion-free intervals (TFIs) during first-line therapy (1LT) with survival are sparse. We evaluated HR-MDS patients receiving 1LT diagnosed from 1/1/2008 to 7/31/2015 and the impact of a TFI (≥60-day interval without transfusions) on progression-free and overall survival (PFS, OS) using Cox proportional-hazard models. Two hundred and twenty-nine HR-MDS patients received 1LT; overall, median PFS/OS were 8.4 months and 14.7 months, respectively. Two-year PFS/OS were 22.3% and 34.6%, respectively. Median PFS/OS were longer for patients with vs. without a TFI (16.9 vs. 6.1 months and 26.1 vs. 11.8 months, respectively; p < .01 [both]). Two-year PFS (43.0% vs. 3.9%; p < .01) and 2-year OS (51.8% vs. 22.5%; p < .01) were also longer in patients with a TFI vs. not. Achievement of a TFI during 1LT appears to positively affect PFS and OS in HR-MDS patients.

Economic Burden of Patients Treated for Higher-Risk Myelodysplastic Syndromes (HR-MDS) in Routine Clinical Care in the United States.

BACKGROUND AND OBJECTIVE: Significant clinical burden is associated with higher-risk myelodysplastic syndromes (HR-MDS); however, the economic burden has not been fully examined. We examined cost of care and healthcare utilization (HCU) in HR-MDS patients engaged in routine care in the United States (US). METHODS: Adult US patients diagnosed with HR-MDS from 1/1/2008 to 10/31/2015 were identified from the Optum database. Patients were followed until death, progression to acute myeloid leukemia (AML), end of enrollment, or end of study (12/31/2015). Myelodysplastic syndrome (MDS)-related costs/HCU (including medical/pharmacy claims with a primary diagnosis of MDS, MDS-related treatment, or supportive care) and non-MDS-related costs/HCU were evaluated. Costs were calculated as per-patient per-month (PPPM) costs adjusted to 2015 US dollars. RESULTS: Of the 209 HR-MDS patients included, median follow-up was 9.9 months (interquartile range 4.6-17.9), and 69.4% had at least one inpatient admission, 56.9% had at least one emergency department visit, and nearly all patients had at least one outpatient visit. Average PPPM costs over follow-up were $17,361; year 1 versus year 2 costs were higher ($17,337 vs $12,976) following HR-MDS diagnosis. The majority of costs were for MDS-related medical services ($10,327 PPPM). MDS-related medical PPPM costs decreased from $10,557 (year 1) to $6530 (year 2). The main drivers of MDS-related medical costs and the decrease in year 2 were chemotherapy and supportive care costs. CONCLUSIONS: The economic burden of HR-MDS is considerable, particularly within the first year of diagnosis. Treatment/supportive care costs accounted for a significant portion of MDS-related costs. As HR-MDS treatment evolves, the economic impact and HCU need to be further investigated.

Cardiovascular comorbidities in a United States patient population with hemophilia A: A comprehensive chart review.

PURPOSE: Previous retrospective claims database analyses reported increased prevalence and earlier onset of cardiovascular comorbidities in patients with versus without hemophilia A. A comprehensive chart review was designed to further investigate previous findings. METHODS: This retrospective chart review study was conducted at Henry Ford Health System (Detroit, MI, USA). Baseline demographics, bleeding events, treatment parameters, coexisting diseases, hemophilia-associated events, Charlson Comorbidity Index score, and prevalence of 12 cardiovascular risk factors and associated diseases were compared between hemophilia A and control cohorts. P values from a chi-square test for categorical variables and a t test for continuous variables were calculated. Because of small sample sizes (N = 0-90, most <50), statistical differences between cohorts were also assessed using absolute standardized difference. RESULTS: Both groups were well matched by age, race, healthcare payer, and study year. The Charlson Comorbidity Index score was similar between groups. Prevalence of bleeds, hepatitis B and C, and HIV/AIDS was higher in the hemophilia cohort. Hemophilia A severity was severe, moderate, mild, or unknown in 52.7%, 10.8%, 10.8%, and 25.7% of patients, respectively. Prevalence of 12 cardiovascular risk factors and diseases was numerically higher in the control cohort, but differences were statistically significant (P ≤ 0.05) only for diabetes and hyperlipidemia. Meaningful statistical differences using standardized differences were not reached for venous and arterial thrombosis and atrial fibrillation. CONCLUSIONS: This retrospective chart review did not confirm statistically significant differences in cardiovascular comorbidities and their earlier onset in hemophilia A versus controls. Results suggest numerically higher comorbidities in controls.

Economic burden of elderly patients with acute myeloid leukemia treated in routine clinical care in the United States.

This retrospective claims database study examined healthcare utilization (HCU) and costs associated with acute myeloid leukemia (AML) in 237 elderly patients who received chemotherapy or a stem cell transplant (SCT) following AML diagnosis. Patients with secondary AML were excluded. Over the entire follow-up period, 92.0% of patients had ≥1 inpatient admission; 85.7% had ≥1 AML-related admission, and 42.6% had ≥1 non-AML-related admission. During inpatient admissions, 39.2% of patients had ≥1 intensive care unit (ICU) admission, with 20.7% having ≥1 AML-related ICU admission, and 27.8% having ≥1 non-AML-related ICU admission. Total mean per-patient per-month (PPPM) costs over the follow-up period were $25,243 (SD: $21,909), with costs from Year 1 ($27,756 [SD: $22,121]) more than double those in Year 2 ($12,953 [SD: $26,334]) following AML diagnosis. The majority of total costs were medical ($24,512 PPPM [SD: $21,704]), which included inpatient admissions ($6548 PPPM [SD: $10,777]), other outpatient visits ($5021 PPPM [SD: $7997]), supportive care ($3640 PPPM [SD: $5589], and chemotherapy administration ($2029 PPPM [SD: $2345]). Healthcare costs of treated elderly AML patients are substantial, particularly in the first year following diagnosis. Further research is needed to understand factors contributing to high costs in various settings of care for elderly AML patients.

Economic burden of patients with diffuse large B-cell and follicular lymphoma treated in the USA.

AIM: Evaluate healthcare costs and utilization of treated diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) patients. MATERIALS & METHODS: Adults with newly diagnosed DLBCL and FL between 1 January 2008 and 31 October 2015 were identified in the Optum™ claims database. Healthcare costs and utilization were assessed from diagnosis date until end of follow-up. RESULTS: A total of 1267 DLBCL- and 1595 FL-treated patients were identified. Mean per-patient, per-month cost during follow-up was US$11,890 for DLBCL and US$10,460 for FL. Healthcare costs and utilization decreased from year 1 to 2 following diagnosis, due to a decrease in chemotherapy services, inpatient admissions and other outpatient services. CONCLUSION: The economic burden of treated DLBCL and FL is considerable, especially in the first year following diagnosis.

Comparative evaluation of treatment patterns and healthcare utilization of newly-diagnosed rheumatoid arthritis patients by anti-cyclic citrullinated peptide antibody status.

BACKGROUND: Anti-cyclic citrullinated peptide (CCP) antibody positivity is an established diagnostic factor for severe disease activity and joint damage and a prognostic factor for aggressive disease in rheumatoid arthritis (RA). OBJECTIVE: To compare RA-related treatment, healthcare utilization, and joint erosion between anti-CCP-positive and anti-CCP-negative RA patients. METHODS: Newly-diagnosed RA patients were identified from the Henry Ford Health System database between January 1, 2009 and December 31, 2014; the date of the first RA diagnosis within the study period was the index date. Baseline anti-CCP test was used to categorize patients as anti-CCP-positive or anti-CCP-negative, and outcomes were evaluated in the 6 months post-index. RESULTS: There were 217 anti-CCP-positive and 191 anti-CCP-negative RA patients included in the study. A higher proportion of anti-CCP-positive patients were initiated on RA treatment than anti-CCP-negative patients (70.5% vs 23.0%; p < .0001). More anti-CCP-positive patients received methotrexate (73.2% vs 56.8%; p = .0374), while more anti-CCP-negative patients received hydroxychloroquine (31.8% vs 13.1%; p = .0037) in first-line therapy. A higher proportion of anti-CCP-negative patients were tested for rheumatoid factor (RF) and erythrocyte sedimentation rate (ESR). Of those tested, there were more positive test results in the anti-CCP-positive cohort compared to the anti-CCP-negative cohort (RF: 84.4% vs 18.2%, p < .0001; C-reactive protein [CRP]: 69.7% vs 48.3%, p = .0008; and ESR: 89.5% vs 53.9%, p < .0001). Outpatient utilization predominated, with more anti-CCP-positive patients having any outpatient physician office visit (96.3% vs 77.5%, p < .0001) and a higher mean number of visits (5.3 vs 2.5, p < .0001) than anti-CCP-negative patients. Among anti-CCP-positive (n = 113) and anti-CCP-negative (n = 58) patients with imaging results, more anti-CCP-positive patients had joint erosion compared to anti-CCP-negative patients (18.6% vs 8.6%; p = .0858); however, statistical significance was not reached. CONCLUSION: RA patients with positive anti-CCP antibodies had higher degrees of inflammation and disease activity as indicated by laboratory results, which likely contributed to their higher rates of healthcare utilization, joint erosion, and proportions of RA treatment.
