A phase 3, multicenter, randomized, double-blind study to evaluate the interchangeability of V114, a 15-valent pneumococcal conjugate vaccine, and PCV13 with respect to safety, tolerability, and immunogenicity in healthy infants (PNEU-DIRECTION).

BACKGROUND: Pneumococcal disease (PD) remains a major health concern globally. In children, pneumococcal conjugate vaccines (PCVs) provide protection against PD from most vaccine serotypes, but non-vaccine serotypes contribute to residual disease. V114 is a 15-valent PCV containing all 13 serotypes in Prevnar 13™ (PCV13) and public health important serotypes 22F and 33F. This phase 3 study evaluated safety and immunogenicity of mixed PCV13/V114 regimens using a 3 + 1 dosing schedule when changing from PCV13 to V114 at doses 2, 3, or 4. METHODS: 900 healthy infants were randomized equally to 5 intervention groups. PCVs were administered in a 3-dose infant series at 2, 4, and 6 months of age followed by a toddler dose at 12-15 months along with concomitant routine vaccines. Safety was evaluated as the proportion of participants with adverse events (AEs). Immunoglobulin G (IgG) responses to the 15 serotypes in V114 were measured at 30 days post-dose 3 and 30 days post-dose 4 (PD4). RESULTS: Frequencies of injection-site and systemic AEs were generally comparable across all intervention groups. At 30 days PD4 (primary endpoint), IgG geometric mean concentrations (GMCs) for the 13 shared serotypes were generally comparable between mixed V114/PCV13 and 4-dose regimens of PCV13 or V114. In mixed regimens at 30 days PD4, a toddler dose of V114 was sufficient to achieve IgG GMCs comparable to a 4-dose regimen of V114 for serotype 22F, while at least one infant dose was needed in addition to the toddler dose to achieve IgG GMCs comparable to a 4-dose regimen of V114 for serotype 33F. CONCLUSIONS: V114 was well tolerated with a generally comparable safety profile to PCV13. For 13 shared serotypes, both mixed regimens and the V114 4-dose regimen induced generally comparable antibody responses to 4-dose regimen with PCV13. Study results support interchangeability of V114 with PCV13 in infants. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03620162; EudraCT: 2018-001151-12.

A phase I randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and immunogenicity of a live-attenuated quadrivalent dengue vaccine in flavivirus-naïve and flavivirus-experienced healthy adults.

Dengue (DENV) is a mosquito-borne virus with four serotypes causing substantial morbidity in tropical and subtropical areas worldwide. V181 is an investigational, live, attenuated, quadrivalent dengue vaccine. In this phase 1 double-blind, placebo-controlled study, the safety, tolerability, and immunogenicity of V181 in baseline flavivirus-naïve (BFN) and flavivirus-experienced (BFE) healthy adults were evaluated in two formulations: TV003 and TV005. TV005 contains a 10-fold higher DENV2 level than TV003. Two-hundred adults were randomized 2:2:1 to receive TV003, TV005, or placebo on Days 1 and 180. Immunogenicity against the 4 DENV serotypes was measured using a Virus Reduction Neutralization Test (VRNT60) after each vaccination and out to 1 year after the second dose. There were no discontinuations due to adverse events (AE) or serious vaccine-related AEs in the study. Most common AEs after TV003 or TV005 were headache, rash, fatigue, and myalgia. Tri- or tetravalent vaccine-viremia was detected in 63.9% and 25.6% of BFN TV003 and TV005 participants, respectively, post-dose 1 (PD1). Tri- or tetravalent dengue VRNT60 seropositivity was demonstrated in 92.6% of BFN TV003, 74.2% of BFN TV005, and 100% of BFE TV003 and TV005 participants PD1. Increases in VRNT60 GMTs were observed after the first vaccination with TV003 and TV005 in both flavivirus subgroups for all dengue serotypes, and minimal increases were measured PD2. GMTs in the TV003 and TV005 BFE and BFN groups remained above the respective baselines and placebo through 1-year PD2. These data support further development of V181 as a single-dose vaccine for the prevention of dengue disease.

Long-term safety and efficacy of sirukumab for patients with rheumatoid arthritis who previously received sirukumab in randomised controlled trials (SIRROUND-LTE).

OBJECTIVE: Interleukin (IL)-6 is a pleiotropic cytokine involved in the pathophysiology of rheumatoid arthritis (RA). Sirukumab is a human monoclonal antibody that binds to IL-6 with high affinity and specificity. METHODS: This long-term extension (LTE) study of the SIRROUND-D and SIRROUND-T studies assessed long-term safety and efficacy of sirukumab in adults with moderate-to-severe RA refractory to conventional disease-modifying antirheumatic drug therapy or antitumor necrosis factor agents. Patients received sirukumab 100 mg subcutaneously (SC) every 2 weeks (q2w) or sirukumab 50 mg SC every 4 weeks (q4w). RESULTS: 1820 patients enrolled in the LTE; median exposure was 2.34 and 2.07 years in sirukumab 50 mg q4w and 100 mg q2w groups, respectively. Adverse events (AEs) occurred in similar proportions between groups, with the exception of major adverse cardiovascular events (MACE), which were more common in the 50 mg q4w versus 100 mg q2w group (2.2% vs 1.0%), and injection-site reactions, more common in the 100 mg q2w group versus 50 mg q4w group (7.5% vs 3.7%). The most common serious AEs were infections (10% of the patients); 32 (1.8%) patients died during the study (primarily from serious infection and MACE). Malignancies were reported in 24 (1.3%) patients. Gastrointestinal perforations, hepatobiliary abnormalities and changes in laboratory parameters were rare. Reductions in RA signs and symptoms and improvements in physical function were maintained throughout the LTE. CONCLUSIONS: The safety profile of sirukumab in the LTE remained consistent with that reported in SIRROUND-D and SIRROUND-T and efficacy was maintained. TRIAL REGISTRATION NUMBER: NCT01856309.

Toward Accelerated Authorization and Access to New Medicines for Juvenile Idiopathic Arthritis.

A meeting was organized to bring together multiple stakeholders involved in the testing and authorization of new medications for juvenile idiopathic arthritis (JIA) to discuss current issues surrounding clinical trials and access to new medications for children and adolescents with JIA. The Childhood Arthritis and Rheumatology Research Alliance invited representatives of regulatory agencies (Food and Drug Administration and European Medicines Agency), and major pharmaceutical companies with JIA-approved products or products in development, patient and parent representatives, representatives of an advocacy organization (Arthritis Foundation), and pediatric rheumatology clinicians/investigators to a 1-day meeting in April 2018. The participants engaged in discussion regarding issues in clinical trials. As the pharmacologic options to treat inflammatory arthritis rapidly expand, registration trial designs to test medications in JIA patients must adapt. Many methodologies successfully used in the recent past are no longer feasible. The pool of patients meeting entry criteria who are willing to participate is shrinking while the number of medications to be tested is growing. Suggested solutions included proposing innovative clinical trial methods to regulatory agencies, as well as open discussions among stakeholders. Ensuring that new medications are authorized in a timely manner to meet the needs of JIA patients worldwide is critical. Approaches should include open dialog between regulatory agencies, pharmaceutical companies, and other stakeholders to develop and implement novel study designs, including patient and clinician perspectives to define meaningful trial outcomes, and changing existing study plans.

Hydroxychloroquine Use Is Associated With Decreased Incident Cardiovascular Events in Rheumatoid Arthritis Patients.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in rheumatoid arthritis (RA) patients. This study is the first to report the association of hydroxychloroquine (an antirheumatic medication that has been associated with decreased risk of diabetes, a less atherogenic lipid profile, and antithrombotic properties) with CVD in RA. METHODS AND RESULTS: A retrospective incident RA cohort from January 1, 2001, to October 31, 2013, excluding patients with CVD prior to RA diagnosis, was constructed. Patients were categorized as hydroxychloroquine users versus nonusers and were allowed to contribute time to either group according to hydroxychloroquine exposure. The primary outcome was adjudicated incident CVD defined as a composite of coronary artery disease, stroke, transient ischemic attack, sudden cardiac death, and peripheral artery disease with arterial revascularization procedure. The secondary outcome was a composite of incident coronary artery disease, stroke, and transient ischemic attack. Cox time-varying regression models were used to estimate the association between hydroxychloroquine exposure and development of CVD, after adjusting for propensity score and relevant confounders, including demographics, CVD-related comorbidities, RA severity, and activity indicators and medications. We included 1266 RA patients, 547 hydroxychloroquine users, and 719 nonusers. During the observation period, 102 CVD events occurred, 3 in hydroxychloroquine users and 99 in nonusers. The fully adjusted Cox model showed a hazard ratio of 0.28 (95% CI 0.12-0.63, P=0.002) for incident CVD and 0.30 (95% CI 0.13-0.68, P=0.004) for incident composite coronary artery disease, stroke, and transient ischemic attack for hydroxychloroquine users versus nonusers, respectively. CONCLUSION: In this hypothesis-generating study, hydroxychloroquine use was associated with a 72% decrease in the risk of incident CVD in RA patients. If these preliminary results are confirmed in larger studies, our findings may be used as a rationale for a randomized study of hydroxychloroquine use for primary prevention of CVD in RA or nonrheumatic high-risk patients.

Glucocorticoid use is associated with increase in HDL and no change in other lipids in rheumatoid arthritis patients.

The aim of this article was to examine the association of glucocorticoid use and dose and changes in the lipid profile in rheumatoid arthritis (RA) patients. RA patients between January 1, 2001, and November 30, 2011, who received oral or intravenous glucocorticoids and who had lipid levels within 1 year before and 1 year after ongoing (at least 3 months) glucocorticoids use along with RA patients who did not take glucocorticoids (controls) were included. Glucocorticoid exposure was calculated as a weighted daily dose in prednisone equivalents and analyzed using as cutoff dose prednisone equivalent of 7.5 mg/day. Outcomes were changes in high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol (TC), triglycerides, and TC/HDL ratio and were calculated in linear regression models adjusting for relevant confounders. In total, 202 subjects on glucocorticoids and 436 controls were included. The glucocorticoid group of ≥7.5 mg/day had the greatest increase in HDL of 6.0 mg/dL (p = 0.003 compared to controls) with lower increases of 3.1 and 2.4 mg/dL in the glucocorticoid group of <7.5 mg/day and controls, respectively. There were no significant differences in other parameters of the lipid profile between the two glucocorticoid groups and controls. In this RA cohort, glucocorticoid dose equivalent of prednisone ≥7.5 mg/day was associated with increased HDL and no change in LDL or TC/HDL ratio compared to no glucocorticoid use These results suggest that this glucocorticoid dose is not associated with an atherogenic lipid profile in RA, a finding that is important in this patient population at high risk for cardiovascular disease.

Low vitamin D level is not associated with increased incidence of rheumatoid arthritis.

To evaluate the association of vitamin D level with incident rheumatoid arthritis (RA) in a patient population using electronic health records (EHR). Case-control study with data extracted from EHR from 1/1/2001 to 12/31/2012 in the Geisinger Health System (GHS). Incident RA was defined as International Classification of Disease-9 code 714.0 twice by a GHS rheumatologist. Patients were identified at time of RA diagnoses and were matched 1:5 for age and gender with non-RA controls. Vitamin D levels were identified and extracted prior to RA diagnosis. The subjects were followed retrospectively with regard to their vitamin D levels; the most recent value of vitamin D prior to the RA diagnosis was used in the analysis. Vitamin D levels were treated both as continuous and categorical with two different cutoff values, 30 and 20 ng/ml. The association between vitamin D and RA was presented as the odds ratios with 95 % confidence intervals (OR, 95 % CI) from a conditional logistic regression model adjusting for obesity and smoking status. A total of 270 patients with incident RA and 1,341 matched controls were identified. The RA patients were 83.3 % female with median age at RA diagnosis of 62 years. The adjusted OR (95 % CI) for the association of vitamin D levels with incident RA compared with controls was 1.00 (0.99, 1.01), 0.98 (0.75, 1.29) and 1.12 (0.80, 1.57) for continuous, <30 and <20 ng/ml vitamin D levels, respectively. Subgroup analysis according to gender or rheumatoid factor positivity yielded similar results. In this patient population, vitamin D levels were not associated with the development of RA.

Tumor necrosis factor α inhibitor use and decreased risk for incident coronary events in rheumatoid arthritis.

OBJECTIVE: To determine the association of tumor necrosis factor α (TNFα) inhibitors with risk for cardiovascular disease (CVD) in rheumatoid arthritis (RA) patients. METHODS: A retrospective cohort of 2,101 incident RA patients was established. Medication exposure was categorized into the following groups: TNFα inhibitors alone or in combination with methotrexate (MTX; aTNF group); MTX alone or in combination with other nonbiologic disease-modifying antirheumatic drugs (DMARDs; MTX group); and no MTX, nonbiologic DMARDs (reference group). Primary outcome was adjudicated incident coronary artery disease (CAD), defined as myocardial infarction, unstable angina, or coronary revascularization procedure. Secondary outcome was adjudicated incident CVD, defined as a composite of CAD, stroke, transient ischemic attack, abdominal aortic aneurysm, peripheral arterial disease, or arterial revascularization procedure. Cox regression models were used to calculate the hazard ratio for CAD and CVD for the aTNF and MTX groups compared to the reference group. RESULTS: There were 46 incident CAD and 82 incident CVD events. Adjusting for covariates associated with CAD and CVD, the hazard ratio for incident CAD was 0.45 (95% confidence interval [95% CI] 0.21-0.96) for the aTNF group and 0.54 (95% CI 0.27-1.09) for the MTX group compared to the reference group. Use of TNFα inhibitors for >16.1 months was associated with a relative risk for CAD of 0.18 (95% CI 0.06-0.50) and for CVD of 0.31 (95% CI 0.15-0.65) compared to the reference group. A similar, although not significant, trend was seen with the MTX group. CONCLUSION: Use of TNFα inhibitors is associated with a decreased risk for CAD in RA; the risk decreases further with long-term use. This should be considered when weighing the risks versus benefits of these medications.

Aspirin use in rheumatoid arthritis patients with increased risk of cardiovascular disease.

Objectives. To examine the patterns of low-dose aspirin use in rheumatoid arthritis (RA) patients with high risk for coronary artery disease (CAD). Methods. Cross-sectional study of 36 consecutive RA patients with a Framingham score ≥10% for CAD. Eligible RA patients were provided with a questionnaire on CAD risk factors and use of low-dose aspirin. For aspirin nonusers, the reason for nonuse was requested by both the patient and rheumatologist. Questions for patients included physician's advice, self-preference, history of gastrointestinal bleeding, allergy to aspirin, or concomitant use of other anti-inflammatory medications. Questions for rheumatologists included awareness of the increased CAD risk, attribution, patient preference, history of gastrointestinal bleeding, allergy to aspirin, and medication interactions. Results. Patients participated in the study; 8 patients reported using daily aspirin, while 23 patients did not. The main reason cited by patients for not taking aspirin was that they were not instructed by their primary care physician (PCP) to do so (n = 16), which was also the main reason cited by rheumatologists (n = 9). Conclusion. This study confirmed underutilization of aspirin in RA patients at high risk for CAD, largely due to the perception that this is an issue which should be handled by the PCP.

Tumor necrosis factor-α inhibitor use is not associated with lipid changes in rheumatoid arthritis.

OBJECTIVE: To determine the association of use of tumor necrosis factor-α (TNF-α) inhibitors with differences in lipid levels in patients with rheumatoid arthritis (RA). METHODS: We studied 807 patients with incident RA to compare differences in lipid levels in TNF-α inhibitor users versus nonusers, with adjustment for relevant covariables. RESULTS: TNF-α inhibitor use was not associated with differences in levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), triglycerides, LDL:HDL, or TC:HDL compared to nonusers. CONCLUSION: Use of TNF-α inhibitor was not associated with differences in lipid levels in patients with RA.

Diabetes mellitus risk in rheumatoid arthritis: reduced incidence with anti-tumor necrosis factor α therapy.

OBJECTIVE: To examine the association of tumor necrosis factor α (TNFα) inhibitor use and the risk of developing diabetes mellitus in a rheumatoid arthritis (RA) inception cohort. METHODS: Adults diagnosed with RA between January 1, 2001, and December 31, 2009, were identified (n = 1,881). Prevalent cases of diabetes mellitus (n = 294) were excluded. Information on sociodemographic data, medical history, body mass index (BMI), laboratory measures, and medications was collected from the electronic health record. Incident diabetes mellitus was defined using the 2010 American Diabetes Association criteria or physician-established diagnosis. Time-varying Cox proportional hazards regression models were used to adjust for age, sex, race, BMI, rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP), erythrocyte sedimentation rate (ESR), and use of nonsteroidal antiinflammatory drugs (NSAIDs), glucocorticoids, hydroxychloroquine, and methotrexate. RESULTS: A total of 1,587 incident RA patients without diabetes mellitus were included. The anti-TNFα users (n = 522) had a lower median age but greater baseline BMI; maximum ESR, RF, and anti-CCP positivity; and NSAID, glucocorticoid, or methotrexate use. The median followup time for the ever and never TNFα inhibitor users was 44.9 months (interquartile range [IQR] 23.7-73.0 months) and 37.1 months (IQR 16.3-65.1 months), respectively (P < 0.001). Of the 91 patients developing diabetes mellitus, 16 were ever and 75 were never TNFα inhibitor users, yielding incidence rates of 8.6 and 17.2 per 1,000 person-years (P = 0.048), respectively. Adjusting for covariates, the hazard ratio for incident diabetes mellitus in TNFα inhibitor users was 0.49 (95% confidence interval 0.24-0.99, P = 0.049) compared to the never users. CONCLUSION: In this inception RA cohort, anti-TNFα use was associated with a 51% reduction in risk of developing diabetes mellitus.

Hydroxychloroquine use associated with improvement in lipid profiles in rheumatoid arthritis patients.

OBJECTIVE: Cardiovascular disease (CVD) is the leading cause of death in patients with rheumatoid arthritis (RA). Disease-modifying therapies that improve risk factors for CVD, such as dyslipidemia, are desired. This study used an electronic health record to determine if hydroxychloroquine (HCQ) use was associated with an improvement in lipid levels in an inception RA cohort. METHODS: All adult individuals with the initial diagnosis of RA between January 1, 2001, and March 31, 2008, were identified (n=1,539). Only patients with at least one lipid level post-RA diagnosis were included (n=706). Information on demographics, medical history, body mass index (BMI), laboratory measures, and medications were collected at office visits. Potential risk and protective factors for dyslipidemia were controlled for in linear mixed-effects regression models for low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol, triglycerides, LDL/HDL, and total cholesterol/HDL. RESULTS: Patients were 69% women and 98% white, with a median age of 65 years and a median BMI of 29.8 kg/m2. In the adjusted regression models, HCQ use was associated with the following average differences in lipids: LDL decrease of 7.55 mg/dl (P<0.001), HDL increase of 1.02 mg/dl (P=0.20), total cholesterol decrease of 7.70 mg/dl (P=0.002), triglycerides decrease of 10.91 mg/dl (P=0.06), LDL/HDL decrease of 0.136 (P=0.008), and total cholesterol/HDL decrease of 0.191 (P=0.006), which were stable over time. CONCLUSION: Use of HCQ in this RA cohort was independently associated with a significant decrease in LDL, total cholesterol, LDL/HDL, and total cholesterol/HDL. Considering these results, its safety profile, and low cost, HCQ remains a valuable initial or adjunct therapy in this patient population at high risk for CVD.

Hydroxychloroquine use and decreased risk of diabetes in rheumatoid arthritis patients.

BACKGROUND/OBJECTIVES: Several studies have associated hydroxychloroquine use with decreased risk of diabetes mellitus (diabetes) or improved glycemic control in rheumatoid arthritis patients, but the studies were small or used data from self-report. The present study sought to replicate this protective relationship in a health system using electronic health records with laboratory data and physician diagnoses. METHODS: This study is a retrospective cohort of 1127 adults with newly diagnosed rheumatoid arthritis and no diabetes within the Geisinger Health System between January 1, 2003, and March 31, 2008. Patients were classified as ever users (n = 333) or never users (n = 794) of hydroxychloroquine. Incident diabetes cases were defined using 2010 American Diabetes Association criteria. RESULTS: The median follow-up times for the ever and never hydroxychloroquine users were 26.0 and 23.0 months, respectively (P = 0.28). The median duration of hydroxychloroquine exposure was 14.0 months. Of the 48 cases developing diabetes during observation, 3 were exposed to hydroxychloroquine at time of development and 45 were nonexposed, yielding incidence rates of 6.2 and 22.0 per 1000 per year (P = 0.03), respectively. In time-varying Cox proportional hazards regression models adjusting for sex, age, body mass index, positive rheumatoid factor and anti-cyclic citrullinated peptide antibodies, erythrocyte sedimentation rate, and nonsteroidal anti-inflammatory drug, glucocorticoid, methotrexate, and tumor necrosis factor α inhibitor use, the hazard ratio for incident diabetes among hydroxychloroquine users was 0.29 (95% confidence interval, 0.09-0.95; P = 0.04) compared with nonusers. CONCLUSIONS: Our findings support the potential benefit of hydroxychloroquine in attenuating the risk of diabetes in rheumatoid arthritis patients. Further work is needed to determine its potential preventive role in other groups at high risk for diabetes.

Patterns of preventive health services in rheumatoid arthritis patients compared to a primary care patient population.

To determine the proportion of rheumatoid arthritis (RA) patients receiving preventive health care according to US Preventive Services Task Force recommendations compared with a community-based population sample, with emphasis on dyslipidemia testing, given the increased risk of cardiovascular disease (CVD) in RA patients. Patients with RA (ICD-9 code 714.0 at ≥2 office visits with a rheumatologist) and a primary care physician (PCP) at the Geisinger Health System (GHS) were identified through electronic health records. The records were searched back from 3/31/08 for the length of time required to satisfy each outcome measure. Percentages were compared with population testing rates using the Pearson Chi-square test. Eight hundred and thirty-one RA patients were compared to 169,476 subjects with a PCP at GHS, stratified by gender and age. Patients with RA were more likely to have had dyslipidemia and osteoporosis testing compared with the general population (86 vs. 75 and 75 vs. 55%, respectively, P < 0.0001 for both). The proportion of RA patients receiving breast and cervical cancer testing was similar to the general population. The majority (79%) of lipid testing was ordered by PCPs. Those RA patients with recommended lipid testing had more traditional CVD factors (hypertension, diabetes, coronary artery disease). RA patients are screened more than the general population for two RA-related co-morbidities, i.e. dyslipidemia and osteoporosis. The RA patients with traditional cardiovascular risk factors are more likely to be tested for dyslipidemia. Further work is warranted to improve testing for modifiable CVD risk factors in this group with multiple co-morbidities.

American College of Rheumatology quality indicators for rheumatoid arthritis: benchmarking, variability, and opportunities to improve quality of care using the electronic health record.

OBJECTIVE: To measure how rheumatologists across our health system performed with the American College of Rheumatology (ACR) quality indicators (QIs) for rheumatoid arthritis (RA) and methotrexate (MTX) drug safety, and to develop opportunities for improvement. METHODS: An electronic health record (EHR) review of 1,062 unique RA patients seen by 15 rheumatologists in a 1-year period was performed. Percentage of each QI met, reasons why the metric was not met, and performance of rheumatologists based on years of experience were evaluated. RESULTS: The percentage met was high for QI-2 (RA disease-modifying antirheumatic drug use; 94%), QI-3 (intervention if RA worse; 85%), and QI-4 (MTX risks discussion; 87%). Percentage met was lower for QI-1 (RA core data set; 69%), QI-5 (MTX baseline studies; 41%), and QI-6 (MTX followup studies; 46%). QI-1 and QI-5 were low due to most physicians missing a single test, and QI-6 was low because of few physicians driving the percentage down. Better QI performance was seen in rheumatologists with 10 years of experience for QI-1 (90% versus 64%; odds ratio [OR] 4.21, P = 0.004) and QI-3 (96% versus 82%; OR 4.47, P = 0.019). EHR chart review for this population required 179.3 hours. CONCLUSION: Measurement allows us to better understand the quality of care that we deliver. In this systematic benchmarking of the ACR QIs in a large RA cohort, performance was excellent in RA treatment-related QIs. Significant variability was noted in RA and MTX monitoring measures, which can be addressed using process redesign techniques.
