ABSTRACT

OBJECTIVE: To evaluate the regional variation of cost sharing and associations with rheumatoid arthritis (RA) disease burden in the US. METHODS: Patients with RA from rheumatology practices in Northeast, South, and West US regions were evaluated. Sociodemographics, RA disease status, and comorbidities were collected, and Rheumatic Disease Comorbidity Index (RDCI) score was calculated. Primary insurance types and copay for office visits (OVs) and medications were documented. Univariable pairwise differences between regions were conducted, and multivariable regression models were estimated to evaluate associations of RDCI with insurance, geographical region, and race. RESULTS: In a cohort of 402 predominantly female, White patients with RA, most received government versus private sponsored primary insurance (40% vs. 27.9%). Disease activity and RDCI were highest for patients in the South region, where copays for OVs were more frequently more than $25. Copays for OVs and medications were less than $10 in 45% and 31.8% of observations, respectively, and more prevalent in the Northeast and West patient subsets than in the South subset. Overall, RDCI score was significantly higher for OV copays less than $10 as well as for medication copays less than $25, both independent of region or race. Additionally, RDCI was significantly lower for privately insured than Medicare individuals (RDCI -0.78, 95% CI [-0.41 to -1.15], P < 0.001) and Medicaid (RDCI -0.83, 95% CI [-0.13 to -1.54], P = 0.020), independent of region and race. CONCLUSION: Cost sharing may not facilitate optimum care for patients with RA, especially in the Southern regions. More support may be required of government insurance plans to accommodate patients with RA with a high disease burden.

ABSTRACT

OBJECTIVE: Our objective was to evaluate the factors associated with regional variation of rheumatoid arthritis (RA) disease burden in the US. METHODS: In a retrospective cohort analysis of Rheumatology Informatics System for Effectiveness (RISE) registry data, seropositivity, RA disease activity (Clinical Disease Activity Index [CDAI], Routine Assessment of Patient Index Data-version 3 [RAPID3]), socioeconomic status (SES), geographic region, health insurance type, and comorbidity burden were recorded. An Area Deprivation Index score of more than 80 defined low SES. Median travel distance to practice sites' zip codes was calculated. Linear regression was used to analyze associations between RA disease activity and comorbidity adjusting for age, sex, geographic region, race, and insurance type. RESULTS: Enrollment data for 184,722 patients with RA from 182 RISE sites were analyzed. Disease activity was higher in African American patients, in those from Southern regions, and in those with Medicaid or Medicare coverage. Greater comorbidity was prevalent in patients in the South and those with Medicare or Medicaid coverage. There was moderate correlation between comorbidity and disease activity (Pearson coefficient: RAPID3 0.28, CDAI 0.15). High-deprivation areas were mainly in the South. Less than 10% of all participating practices cared for more than 50% of all Medicaid recipients. Patients living more than 200 miles away from specialist care were located mainly in Southern and Western regions. CONCLUSION: A disproportionately large portion of socially deprived, high comorbidity, and Medicaid-covered patients with RA were cared for by a minority of rheumatology practices. Studies are needed in high-deprivation areas to establish more equitable distribution of specialty care for patients with RA.

ABSTRACT

OBJECTIVE: To evaluate changes in bone turnover and bone mineral density (BMD) in patients with rheumatoid arthritis (RA) receiving glucocorticoids, after discontinuation of denosumab for 12 months. METHODS: We conducted a randomized, double-blind, placebo-controlled, phase II study of RA patients. Patients received placebo, denosumab 60 mg, or denosumab 180 mg every 6 months for 12 months and were followed up for an additional 12 months after discontinuation, during which no bone loss prevention therapy was instituted. Changes from baseline in serum C-terminal telopeptide of type I collagen (CTX), serum procollagen type I N-terminal propeptide (PINP), and lumbar spine and total hip BMD were evaluated. RESULTS: In this post hoc analysis of patients treated with glucocorticoids at study baseline (n = 82), levels of CTX and PINP decreased significantly from baseline in both denosumab groups. Following denosumab discontinuation, CTX returned to baseline and was not significantly different from the placebo group 6 and 12 months after discontinuation. Median percentage changes from baseline PINP in those treated with denosumab 60 mg were -0.16% and 15.3% at 6 and 12 months, respectively, after discontinuation (P = 0.062 and P = 0.017, versus placebo); corresponding changes with denosumab 180 mg were 9.0% and 75.8%, respectively (P = 0.018 and P = 0.002 versus placebo). Compared to placebo, lumbar spine and total hip BMD increased in patients receiving denosumab and returned to baseline 12 months after discontinuation. No osteoporotic fractures were reported during treatment or in the off-treatment period. CONCLUSION: In this analysis of short-term denosumab use in RA patients receiving glucocorticoids, denosumab discontinuation resulted in a gradual increase in bone turnover, which was associated with a return to baseline lumbar spine and total hip BMD.

ABSTRACT

OBJECTIVE: Comorbidities in rheumatoid arthritis (RA) can influence treatment selection, impact treatment persistency, and increase health care costs. This study assessed the magnitude of comorbidity burden via epidemiology (incidence and prevalence) and associated costs of select comorbidities in RA patients: anemia, malignancy, venous thromboembolism (VTE), major adverse cardiovascular events (MACE), and infections, stratified by history of disease-modifying antirheumatic drug (DMARD) exposure. METHODS: From the IQVIA PharMetrics® Plus database, we selected adult patients with RA (2 or more RA diagnostic codes at least 30 days apart) at initiation of a new DMARD (DMARD-naïve), after the first conventional synthetic DMARD (csDMARD) or after the first biologic DMARD (bDMARD). We assessed pre-index prevalence (percentage) and on-treatment incidence (per 100 patient-years [P100PY]) of the aforementioned comorbidities. For patients with versus without incident conditions, we compared total all-cause health care costs as unadjusted and adjusted for baseline characteristics and health care costs. RESULTS: Prior to initiating a new treatment, among DMARD-naïve patients (N = 28,201), csDMARD switchers (N = 7,816), or bDMARD switchers (N = 4,656), the overall prevalence ranged from 14.1% to 16.2% (anemia), from 1.3% to 5.2% (malignancy, evaluated in csDMARD and bDMARD switchers), from 1.5% to 2.1% (VTE), from 1.8% to 2.9% (MACE), and from 66.6% to 76.1% (infections). Once on index treatment, overall incidence (P100PY) among the cohorts ranged from 6.9 to 8.9 (anemia), from 2.0 to 2.3 (malignancy), from 0.7 to 0.9 (VTE), from 1.6 to 2.0 (MACE), and from 77.4 to 87.7 (infections). The incident comorbidities (except herpes zoster) were associated with increased adjusted health care costs. CONCLUSION: Anemia, malignancy, VTE, MACE, and infections affect patients with RA at all stages of their treatment journey and are associated with increased health care costs.

ABSTRACT

In the randomized, placebo-controlled, double-blind phase 3 ACTIVE study (NCT01343004), 18 months of abaloparatide 80 µg daily (subcutaneous injection) in postmenopausal women at risk of osteoporotic fracture significantly reduced the risk of vertebral, nonvertebral, clinical, and major osteoporotic fractures and significantly increased bone mineral density (BMD) versus placebo regardless of baseline risk factors. Women from the abaloparatide and placebo groups who completed ACTIVE were eligible for ACTIVExtend (NCT01657162), in which all enrollees received sequential, open-label monotherapy with alendronate 70 mg once weekly for up to 24 months. This prespecified analysis evaluated whether fracture risk reductions and bone mineral density (BMD) gains associated with abaloparatide during ACTIVE persisted through the full 43-month ACTIVE-ACTIVExtend study period in nine prespecified baseline risk subgroups. Baseline risk subgroups included BMD T-score at the lumbar spine, total hip, and femoral neck (≤ - 2.5 versus > - 2.5 and ≤ -3.0 versus > - 3.0), history of nonvertebral fracture (yes/no), prevalent vertebral fracture (yes/no), and age (<65 versus 65 to <75 versus ≥75 years). Forest plots display treatment effect. Treatment-by-subgroup interactions were tested using the Breslow-Day test, Cox proportional hazards model, and ANCOVA model. After the combined ACTIVE-ACTIVExtend study period, reductions in relative risk for new vertebral, nonvertebral, clinical, and major osteoporotic fractures were greater among patients in the abaloparatide/alendronate group than among those in the placebo/alendronate group across all nine baseline risk subgroups. BMD gains at the lumbar spine, total hip, and femoral neck were greater in the abaloparatide/alendronate group versus the placebo/alendronate group. No clinically meaningful interaction between treatment assignment and any baseline risk variable was observed. The sequence of abaloparatide for 18 months followed by alendronate for up to 24 months appears to be an effective treatment option for a wide range of postmenopausal women at risk for osteoporotic fractures. © 2019 The Authors.

ABSTRACT

Purpose: In women with postmenopausal osteoporosis, we investigated the effects of 24 months of treatment with alendronate (ALN) following 18 months of treatment with abaloparatide (ABL) or placebo (PBO). Methods: Women who completed ABL or PBO treatment in ACTIVE were eligible to receive up to 24 months of ALN. We evaluated the incidence of vertebral and nonvertebral fractures and changes in bone mineral density (BMD) during the entire 43-month period from ACTIVE baseline to the end of ACTIVExtend and for the 24-month extension only. Results: Five hundred fifty-eight women from ACTIVE's ABL group and 581 from its PBO group (92% of ABL and PBO completers) were enrolled. During the full 43-month treatment period, 0.9% of evaluable women in the ABL/ALN group experienced a new radiographic vertebral fracture vs 5.6% of women in the PBO/ALN group, an 84% relative risk reduction (RRR, P < 0.001). Kaplan-Meier incidence rates for other reported fracture types were significantly lower for ABL/ALN vs PBO/ALN (all P < 0.05). Gains in BMD achieved during ACTIVE were further increased during ACTIVExtend. For ACTIVExtend only, RRR for vertebral fractures was 87% with ABL/ALN vs PBO/ALN (P = 0.001). Adverse events were similar between groups. A supplemental analysis for regulatory authorities found no hip fractures in the ABL/ALN group vs five in the PBO/ALN group. Conclusions: Eighteen months of ABL followed by 24 months of ALN reduced the risk of vertebral, nonvertebral, clinical, and major osteoporotic fractures and increased BMD. Sequential ABL followed by ALN appears to be an effective treatment option for postmenopausal women at risk for osteoporosis-related fractures.

ABSTRACT

Juvenile idiopathic arthritis (JIA) is a group of chronic inflammatory diseases affecting approximately 300,000 children and adolescents in the United States of unknown cause. It can affect children from the age of 0 years up to the age of 16 years. The International League of Associations of Rheumatology has defined seven subsets of JIA based on several factors including the number of affected joints and the involvement of other tissues; the prognosis for each affected child also depends on multiple factors including age of onset, number of joints involved, and systemic features. As with rheumatoid arthritis in adults, the goal of therapy is remission and resolution of disease activity; however, as a cure does not seem attainable in the near future, a reasonable goal of therapy is prevention of joint damage, inhibition of inflammation, and a high level of quality of life. Even with available therapies, many children with JIA enter adulthood with persistently active disease, suboptimal function, and impaired quality of life. Methotrexate remains the standard of care for children with JIA; etanercept was approved in 2000 in the United States for the treatment of JIA resistant to methotrexate. The efficacy and safety of etanercept therapy in children with JIA is reviewed and its place in the therapeutic regimen is discussed; the available long term data is also presented. The data presented was obtained from a PubMed search as well as a review of the references presented in the 2011 American College of Rheumatology Recommendations for the Treatment of Juvenile Idiopathic Arthritis and the 2013 Update. It is hoped that treatment with etanercept and other biologic therapies will lead to improved outcomes for children with JIA in the future.

ABSTRACT

Glucocorticoids are commonly prescribed medications to treat multiple diseases across many medical specialties. One of the most common yet largely unappreciated side effect of glucocorticoid use is increased risk of fracture. Many different therapies are indicated to prevent and treat this condition; many guidelines exist that suggest appropriate use of both glucocorticoids and the medications approved to prevent this common side effect of glucocorticoid therapy. Nevertheless, 30%-50% of patients on long-term glucocorticoid therapy sustain a fracture. Teriparatide, recombinant human parathyroid hormone (1-34), is a daily self-injectable therapy for 24 months approved for use in patients taking long-term glucocorticoids. Teriparatide has been shown to increase bone mineral density and reduce vertebral fracture risk in glucocorticoid-treated patients. Glucocorticoids have many adverse effects on bone that teriparatide has been shown to prevent or negate. Given the fact that preventive therapy for glucocorticoid-induced osteoporosis is often not prescribed, one wonders whether a daily self-injectable therapy for this condition would be prescribed by physicians and accepted by patients. This article reviews the epidemiology, pathophysiology, treatment, guidelines, and persistence data (when available) for patients with glucocorticoid-induced osteoporosis treated with teriparatide.

ABSTRACT

Osteoporosis and fractures that occur as a result of this condition pose a huge public health problem to society and result in morbidity and mortality to individuals. Because osteoporosis is often a result of aging, many people are not aware that therapies exist to reduce the risk of fracture. Until recently, the most common therapies used to treat osteoporosis, the oral bisphosphonates, had an inconvenient and cumbersome mode of administration. Within the last 4 years, two new parenteral antiresorptive drugs to treat osteoporosis were approved by the US Food and Drug Administration. As treatment of osteoporosis may extend for many years, the collection of long-term efficacy and safety data is warranted. This paper discusses data from the extension trials of denosumab and zoledronic acid.

ABSTRACT

Denosumab (Prolia) is a fully human monoclonal antibody directed against receptor activator of nuclear factor-κB ligand (RANKL), which interferes with the formation, activation, and survival of osteoclasts. It was approved by the Food and Drug Administration in June 2010 as a new treatment for postmenopausal osteoporosis in women who are at high risk for fracture. Given its mechanism of action, it is an antiresorptive therapy that is administered as a 60-mg subcutaneous injection every 6 months. It is the first biologic antiresorptive therapy for osteoporosis, and the first osteoporosis therapy to show efficacy and safety in patients with renal impairment.

ABSTRACT

OBJECTIVES: To report results of subgroup analyses of bone mineral density (BMD) and bone turnover markers from a randomised, double-blind, placebo-controlled, phase II study of denosumab, an investigational RANKL inhibitor, in patients with rheumatoid arthritis (RA) concurrently receiving treatment with bisphosphonates or glucocorticoids. METHODS: Patients received subcutaneous placebo (n=75), denosumab 60 mg (n=71) or denosumab 180 mg (n=72) at baseline and 6 months. Assessments included dual x-ray absorptiometry scans of the lumbar spine and hip, and determination of levels of serum type I C-telopeptide (sCTx-I) and serum procollagen 1N-terminal peptide (P1NP). RESULTS: Denosumab treatment increased mean lumbar spine and hip BMD and reduced sCTx-I and P1NP compared with placebo through 12 months, regardless of baseline BMD or marker levels or concomitant bisphosphonate or glucocorticoid use. CONCLUSIONS: This study extends evidence that denosumab increases BMD and reduces bone turnover in patients with RA and may provide a new therapeutic option for reducing systemic bone loss in patients with RA.

ABSTRACT

OBJECTIVE: To determine functionality and acceptability of a new teriparatide (Forteo, Eli Lilly and Company, Indianapolis, IN, USA) delivery device by patients with osteoporosis. RESEARCH DESIGN AND METHODS: This was an eight week, single-arm, multicenter, open-label clinical trial. Patients received teriparatide 20 microg/day by subcutaneous injection using a new delivery device. Men and postmenopausal women with osteoporosis at high risk for fracture were stratified to Current User (n = 92) or Not Current User (n = 107) groups. Current Users had used the original delivery device for > or =8 weeks, including uninterrupted use for four weeks before enrollment. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT00577863. MAIN OUTCOME MEASURES: The primary objective was to detect common complaints (> or =3% for all patients) regarding the functionality and acceptability of the new device. Complaints were categorized as functional (e.g., malfunction), nonfunctional (e.g., size), or user manual. Secondary objectives included questionnaire assessment of preference of the new versus original device, features of the new delivery device, and analysis of adverse events. RESULTS: A total of 31 patients (16%) reported 47 complaints (four functional, 27 nonfunctional, and 16 user manual). There were two common complaints: device size (4.0%) and lack of information on alcohol swabs (3.5%). Overall, patients agreed that the new device was easy to use (99.5%), easy to learn to use (99%), easy to attach a needle (97%), easy to hold while injecting (95%), and that it reduced their reluctance to take injections (90%). Most Current Users (92%) preferred the new delivery device over the original device. Adverse events reported by > or =2% of patients were upper respiratory infection (3.5%), urinary tract infection (2%), influenza (2%), and headache (2%). Limitations include the one-arm study design and the short (eight week) duration of the study. CONCLUSIONS: Patients found the new teriparatide delivery device easy to use and Current Users preferred the new delivery device over the original device.

ABSTRACT

Gout is an inflammatory arthritis that has been recognized since ancient times. It is the most common type of inflammatory arthritis in men. Despite these facts, no new advances have been made in the diagnosis and treatment of gout for over 50 years. Since there have been no new advances and the condition has been recognized for so many centuries, the diagnosis and treatment of gout has not elicited interest in learning more about the disease. Thus, managing gout is a challenge for the clinician caring for the gout patient. Rheumatologists should be the educators of primary care physicians (PCPs) about the diagnosis and optimal treatment of gout. A recent educational meeting was held, the Hyperuricemia and Gout Summit, in which a panel of leading rheumatologists educated PCPs about gout management through didactic presentations and breakout sessions focused on case studies. At this meeting, the PCPs discussed some of their key challenges in managing gout in their practice. This article reviews current recommendations for the diagnosis and treatment of gout, using educational examples from the Hyperuricemia and Gout Summit. It also highlights the importance of providing practical recommendations to PCPs to improve the standard of care for gout in the primary care setting.

ABSTRACT

Synovial fluid aspiration and analysis is the gold standard for making the diagnosis of gout but is not always performed when indicated in clinical practice. In clinical situations when joint aspiration simply cannot be performed, a presumptive (or clinical) diagnosis of gout may be made in consultation with published recommendations and criteria from expert societies. A thorough patient history and physical examination are critical to a presumptive diagnosis of gout, as is serum urate measurement at the time of an acute attack and at follow-up 2 weeks later.

ABSTRACT

OBJECTIVE: RANKL is essential for osteoclast development, activation, and survival. Denosumab is a fully human monoclonal IgG2 antibody that binds RANKL, inhibiting its activity. The aim of this multicenter, randomized, double-blind, placebo-controlled, phase II study was to evaluate the effects of denosumab on structural damage in patients with rheumatoid arthritis (RA) receiving methotrexate treatment. METHODS: RA patients received subcutaneous placebo (n = 75), denosumab 60 mg (n = 71), or denosumab 180 mg (n = 72) injections every 6 months for 12 months. The primary end point was the change from baseline in the magnetic resonance imaging (MRI) erosion score at 6 months. RESULTS: At 6 months, the increase in the MRI erosion score from baseline was lower in the 60-mg denosumab group (mean change 0.13; P = 0.118) and significantly lower in the 180-mg denosumab group (mean change 0.06; P = 0.007) than in the placebo group (mean change 1.75). A significant difference in the modified Sharp erosion score was observed as early as 6 months in the 180-mg denosumab group (P = 0.019) as compared with placebo, and at 12 months, both the 60-mg (P = 0.012) and the 180-mg (P = 0.007) denosumab groups were significantly different from the placebo group. Denosumab caused sustained suppression of markers of bone turnover. There was no evidence of an effect of denosumab on joint space narrowing or on measures of RA disease activity. Rates of adverse events were comparable between the denosumab and placebo groups. CONCLUSION: Addition of twice-yearly injections of denosumab to ongoing methotrexate treatment inhibited structural damage in patients with RA for up to 12 months, with no increase in the rates of adverse events as compared with placebo.

ABSTRACT

Vertebral fractures are the most common osteoporotic fracture and may result in back pain with functional limitations and diminished quality of life. Teriparatide [rhPTH (1-34)] has been shown to increase bone mass and reduce the risk of vertebral and other osteoporotic fractures. The aim of this study was to evaluate the effects of teriparatide on the risk of back pain in patients with osteoporosis. A systematic review of the literature was performed, and five trials were identified and included in our analyses. All trials were randomized, double-blinded, and parallel with either new vertebral fracture (n=1) or bone mineral density as the primary endpoint (n=4). Four studies were in postmenopausal women with osteoporosis, and one was in men with idiopathic or hypogonadal osteoporosis. Two trials were placebo controlled, two trials were alendronate controlled, and one trial involved teriparatide plus hormone replacement therapy versus hormone replacement therapy alone. Reports of back pain, defined as new or worsened back pain after initiating the study drug, were obtained from adverse event databases, and the risk of back pain was analyzed using a multivariate Cox proportional hazards model. Results were not statistically heterogeneous (P=0.60) across trials, and there were no differences between groups administered teriparatide 20 or 40 mcg/day doses (P=0.64). The rates of back pain, moderate or severe back pain, and severe back pain per 100 patient-years were numerically lower in the teriparatide versus comparator groups in each study. Compared with the pooled comparator, patients in the pooled teriparatide group had reduced risk for any back pain [relative risk, 0.66 (95% CI, 0.55-0.80)], moderate or severe back pain [relative risk, 0.60 (95% CI, 0.48-0.75)] and severe back pain [relative risk, 0.44 (95% CI, 0.28-0.68)]. Separate meta-analyses comparing teriparatide versus placebo or antiresorptive drugs gave similar results. In conclusion, patients randomized to teriparatide had a reduced risk of new or worsening back pain compared to patients randomized to placebo, hormone replacement therapy or alendronate.

ABSTRACT

OBJECTIVE: To examine the safety of anakinra when added to a background of standard rheumatoid arthritis (RA) medications in patients with RA with active disease. METHODS: This analysis further evaluates data from the first 6 months of a blinded, placebo controlled safety trial that had a subsequent 30 month, open label portion (not reported here). Patients with RA with a wide range of comorbid conditions, disease activity, and background medications were randomly assigned in a 4:1 allocation ratio to treatment with anakinra 100 mg or placebo administered daily by injection. Safety was assessed by comparing adverse event profiles between anakinra and placebo patients according to concomitant medications received. RESULTS: Anakinra patients (n = 1116) showed no difference in the incidence of upper respiratory infections or overall serious adverse events compared with placebo patients (n = 283). The anakinra group had more injection site reactions (72.6% vs 32.9% in placebo) and a small increase in serious infections (2.1% vs 0.4% in placebo). Anakinra's safety profile did not differ in patients receiving antihypertensive, antidiabetic, or statin drugs. CONCLUSION: This study indicates that anakinra has a good safety profile in patients typically seen in a rheumatology practice who are considered candidates for therapy with agents that are immunomodulatory and disease modifying. Except for injection site reactions and a nonstatistically although potentially clinically significant increase in serious infections in the anakinra versus the placebo groups, the addition of anakinra to a stable background regimen of RA medications introduced no other important safety risk in patients with RA.
