Impact of Race on the Efficacy and Safety of Tofacitinib in Rheumatoid Arthritis: Post Hoc Analysis of Pooled Clinical Trials.

INTRODUCTION: Racial disparities in disease activity, clinical outcomes, and treatment survival persist despite advancements in rheumatoid arthritis (RA) therapies and clinical management. In this post hoc analysis of pooled data from the tofacitinib global clinical program, we evaluated the impact of race on the efficacy and safety of tofacitinib in patients with RA. METHODS: Data were pooled from 15 phase 2-3b/4 studies of patients with RA treated with tofacitinib 5 or 10 mg twice daily, adalimumab, or placebo. Outcomes were stratified by self-reported patient race (White/Black/Asian/Other). Efficacy outcomes to month 12 included: American College of Rheumatology (ACR)20/50/70 responses, Clinical Disease Activity Index (CDAI)/Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] low disease activity (LDA) rates, least squares (LS) mean change from baseline (∆) in CDAI, DAS28-4 (ESR), Health Assessment Questionnaire-Disability Index (HAQ-DI), and Pain [Visual Analog Scale (VAS)]. Odds ratios (ORs; 95% CI) versus placebo, and placebo-adjusted ∆LS means were calculated for active treatments using logistic regression model and mixed-effect model of repeated measurements, respectively. Safety outcomes were assessed throughout. RESULTS: A total of 6355 patients were included (White, 4145; Black, 213; Asian, 1348; Other, 649). For tofacitinib-treated patients, ORs for ACR20/50/70 responses and CDAI/DAS28-4(ESR) LDA rates through month 3 were generally numerically higher for White/Asian/Other versus Black patients. Across active treatments, trends toward higher placebo-adjusted improvements from baseline in CDAI, DAS28-4 (ESR), HAQ-DI, and Pain (VAS) were observed in Asian/Other versus White/Black patients. Numerically higher placebo responses in Black versus White/Asian/Other patients were generally observed across outcomes through month 12. Safety outcomes were mostly similar across treatment/racial groups. CONCLUSIONS: In patients with RA, tofacitinib was efficacious across racial groups with similar safety outcomes; observed racial differences potentially reflect patient demographics or regional practice disparities.

Brepocitinib, a potent and selective TYK2/JAK1 inhibitor: scientific and clinical rationale for dermatomyositis.

Dermatomyositis (DM) is a rare and debilitating, systemic, autoimmune disease. While heterogenous in presentation and severity, DM is primarily characterised by a spectrum of skin and muscle disease, which may include proximal muscle weakness and recalcitrant cutaneous eruptions. DM may also be associated with joint pain and stiffness, inflammatory arthritis, dysphagia, fatigue, and calcinosis. The current standard of care for DM includes glucocorticoids, immunosuppressants, and intravenous immunoglobulin (IVIg). Unfortunately, these medications are not uniformly effective and can lead to adverse events, particularly with chronic use, necessitating discontinuation of therapy. Therefore, a substantial unmet need exists for more tailored and efficacious therapies that target DM pathogenesis. Brepocitinib is an oral, once-daily, novel, and specific TYK2/JAK1 inhibitor. Brepocitinib's potent inhibition of TYK2 and JAK1 reduces the signalling of pro-inflammatory cytokines, including IFN-α/ß, IL-12, IL-23, and IFNγ, that have been implicated in the pathogenesis of DM. Other JAK inhibitors have been used off-label in both case series and open-label clinical trials in patients with DM; and brepocitinib has demonstrated efficacy in phase 2 clinical trials of several other autoimmune diseases, including plaque psoriasis, psoriatic arthritis, Crohn's disease, hidradenitis suppurativa, and ulcerative colitis. Therefore, there is a strong scientific and clinical rationale for the utility and potential effectiveness of brepocitinib in the treatment of DM patients. Currently, the safety, tolerability, and efficacy of brepocitinib is being evaluated in the largest (n=225) double-blind placebo-controlled phase 3 trial in DM patients to date (VALOR - NCT0543726).

Identification of Gaps in Quality of Care and Good Practice Interventions in Rheumatoid Arthritis: Insights From a Literature Review and Qualitative Study of Nine Centers in North America.

OBJECTIVE: Quality of care (QoC) delivery in rheumatoid arthritis (RA) continues to suffer from various challenges (eg, delay in diagnosis and referral) that can lead to poor patient outcomes. This study aimed to identify good practice interventions that address these challenges in RA care in North America. METHODS: The study was conducted in three steps: (1) literature review of existing publications and guidelines (April 2005 to April 2021) on QoC in RA; (2) in-person visits to >50 individual specialists and health care professionals across nine rheumatology centers in the United States and Canada to identify challenges in RA care and any corresponding good practice interventions; and (3) collation and organization of findings of the two previous methods by commonalities to identify key good practice interventions, followed by further review by RA experts to ensure key challenges and gaps in RA care were captured. RESULTS: Several challenges and eight good practice interventions were identified in RA care. The interventions were prioritized based on the perceived positive impact on the challenges in care and ease of implementation. High-priority interventions included the use of technology to improve care, streamlining specialist treatment, and facilitating comorbidity assessment and care. Other interventions included enabling patient access to optimal medication regimens and improving patient self-management strategies. CONCLUSION: Learnings from the study can be implemented in other rheumatology centers throughout North America to improve RA care. Although the study was completed before the COVID-19 pandemic, the findings remain relevant.

Coalition for Health and Gender Equity (CHANGE)-a protocol for a global cross-sectional survey of health and gender equity in rheumatology.

Objectives: The primary aim of the CHANGE survey is to determine the current state of gender equity within rheumatology, and secondarily, to review the physician perspective on bullying, harassment and equipoise of opportunities within rheumatology. Methods: The CHANGE e-survey is a cross-sectional self-reported questionnaire adapted from EULAR's gender equity in academic rheumatology task force. The survey was launched in January 2023; it is available in six languages and distributed widely via rheumatology organizations and social media. Eligible participants include rheumatologist physicians and rheumatology health-care professionals. Survey responses will undergo descriptive analysis and inter-group comparison aiming to explore gender-based discrimination using logistic regression, with subgroup analyses for country/continent variations. Conclusion: This e-survey represents a comprehensive global initiative led by an international consortium, aimed at exploring and investigating the gender-related disparities and obstacles encountered by rheumatologists and rheumatology health-care professionals across diverse communities and health-care environments. By pursuing this initiative, we aim to take the broader rheumatology community a step closer to understanding the underlying origins of inequities and their determinants. Such insights are pivotal in identifying viable interventions and strategies to foster gender equity within the field. Ultimately, our collective objective is to ensure equitable access to opportunities for every individual, irrespective of gender, thereby promoting inclusivity and fairness across the entire spectrum of professional practice and career development.

Embracing unity at OMERACT: Valuing equity, promoting diversity, fostering inclusivity.

OBJECTIVE: To increase awareness and understanding of the principles of Equity, Diversity, and Inclusivity (EDI) within Outcome Measures in Rheumatology's (OMERACT) members. For this, we aimed to obtain ideas on how to promote and foster these principles within the organization and determine the diversity of the current membership in order to focus future efforts. METHODS: We held a plenary workshop session at OMERACT 2023 with roundtable discussions on barriers and solutions to increased diversity within OMERACT. We conducted an anonymous, web-based survey of members to record characteristics including population group, gender identity, education level, age, and ability. RESULTS: The workshop generated ideas to increase diversity of participants across the themes of building relationships [12 topics], materials and methods [5 topics], and conference-specific [6 topics]. Four hundred and seven people responded to the survey (25 % response rate). The majority of respondents were White (75 %), female (61 %), university-educated (94 %), Christian (42 %), spoke English at home (60 %), aged 35 to 55 years (50 %), and did not report a disability (64 %). CONCLUSION: OMERACT is committed to improving its diversity. Next steps include strategic recruitment of members to the EDI working group, drafting an EDI mission statement centering equity and inclusivity in the organization, and developing guidance for the OMERACT Handbook to help all working groups create actionable plans for promoting EDI principles.

Associations of Cost Sharing With Rheumatoid Arthritis Disease Burden.

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.

Geographic Variation in Disease Burden and Mismatch in Care of Patients With Rheumatoid Arthritis in the United States.

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.

Investigating the influence of ultrasound parameters on ibuprofen drug release from hydrogels.

Hydrogels are promising ultrasound-responsive drug delivery systems. In this study, we investigated how different ultrasound parameters affected drug release and structural integrity of self-healing hydrogels composed of alginate or poloxamers. The effects of amplitude and duty cycle at low frequency (24 kHz) ultrasound stimulation were first investigated using alginate hydrogels at 2% w/v and 2.5% w/v. Increasing ultrasound amplitude increased drug release from these gels, although high amplitudes caused large variations in release and damaged the gel structure. Increasing duty cycle also increased drug release, although a threshold was observed with the lower pulsed 50% duty cycle achieving similar levels of drug release to a continuous 100% duty cycle. Poloxamer-based hydrogels were also responsive to the optimised parameters at low frequency (24 kHz, 20% amplitude, 50% duty cycle for 30 s) and showed similar drug release results to a 2.5% w/v alginate hydrogel. Weight loss studies demonstrated that the 2% w/v alginate hydrogel underwent significant erosion following ultrasound application, whereas the 2.5% w/v alginate and the poloxamer gels were unaffected by application of the same parameters (24 kHz, 20% amplitude, 50% duty cycle for 30 s). The rheological properties of the hydrogels were also unaffected and the FTIR spectra remained unchanged after low frequency ultrasound stimulation (24 kHz, 20% amplitude, 50% duty cycle for 30 s). Finally, high-frequency ultrasound stimulation (1 MHz, 3 W.cm-2, 50% duty cycle) was also trialled; the alginate gels were less responsive to this frequency, while no statistically significant impact on drug release was observed from the poloxamer gels. This study demonstrates the importance of ultrasound parameters and polymer selection in designing ultrasound-responsive hydrogels.

Evaluating the quality of municipal strategic plans.

Local governments increasingly use strategic planning as a tool to anticipate and address the complex challenges they face. Strategic planning is the process of setting long-term goals, prioritizing actions to achieve the goals, and mobilizing human and financial resources to execute the actions. Although there has been considerable debate about the appropriate scope, content, and procedures for strategic planning in local government, less attention has been paid to the quality of municipal strategic plans, meaning the presence or absence of key characteristics that analysts typically associate with good plans. This article explores the content and quality of municipal strategic plans in Canada. It presents results of a comparative plan quality evaluation, which assessed the official strategic plans of the 66 most populous Canadian municipalities using a comprehensive set of criteria derived from existing scholarship on plan quality and strategic planning. The findings indicate that there is considerable room to improve municipal strategic plans, which lack many of the features commonly associated with good quality plans. Municipal strategic plans should contain a comprehensive fact base to prioritize and rationalize the goals within the plan, and there should be appropriate provisions for implementing, monitoring, and evaluating plan progress and outcomes.

Patient-reported outcomes of upadacitinib versus abatacept in patients with rheumatoid arthritis and an inadequate response to biologic disease-modifying antirheumatic drugs: 12- and 24-week results of a phase 3 trial.

BACKGROUND: In previous clinical trials, patients with active rheumatoid arthritis (RA) treated with upadacitinib (UPA) have improved patient-reported outcomes (PROs). This post hoc analysis of SELECT-CHOICE, a phase 3 clinical trial, evaluated the impact of UPA vs abatacept (ABA) with background conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) on PROs in patients with RA with inadequate response or intolerance to biologic disease-modifying antirheumatic drugs (bDMARD-IR). METHODS: Patients in SELECT-CHOICE received UPA (oral 15 mg/day) or ABA (intravenous). PROs evaluated included Patient Global Assessment of Disease Activity (PtGA) by visual analog scale (VAS), patient's assessment of pain by VAS, Health Assessment Questionnaire Disability Index (HAQ-DI), morning stiffness duration and severity, 36-Item Short Form Health Survey (SF-36), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Work Productivity and Activity Impairment (WPAI), and EQ-5D 5-Level (EQ-5D-5L) index score. Least squares mean (LSM) changes from baseline to weeks 12 and 24 were based on an analysis of covariance model. Proportions of patients reporting improvements ≥ minimal clinically important differences (MCID) were compared using chi-square tests. RESULTS: Data from 612 patients were analyzed (UPA, n=303; ABA, n=309). Mean age was 56 years and mean disease duration was 12 years. One-third received ≥2 prior bDMARDs and 72% received concomitant methotrexate at baseline. At week 12, UPA- vs ABA-treated patients had significantly greater improvements in PtGA, pain, HAQ-DI, morning stiffness severity, EQ-5D-5L, 2/4 WPAI domains, and 3/8 SF-36 domains and Physical Component Summary (PCS) scores (P<0.05); significant differences persisted at week 24 for HAQ-DI, morning stiffness severity, SF-36 PCS and bodily pain domain, and WPAI activity impairment domain. At week 12, significantly more UPA- vs ABA-treated patients reported improvements ≥MCID in HAQ-DI (74% vs 64%) and SF-36 PCS (79% vs 66%) and 4/8 domain scores (P<0.05). CONCLUSIONS: At week 12, UPA vs ABA treatment elicited greater improvements in key domains of physical functioning, pain, and general health and earlier improvements in HAQ-DI. Overall, more UPA- vs ABA-treated patients achieved ≥MCID in most PROs at all timepoints; however, not all differences were statistically significant. These data, however, highlight the faster response to UPA treatment. TRIAL REGISTRATION: NCT03086343 , March 22, 2017.

Increasing Advocacy Awareness in Early Career Rheumatologists: A Web-Based Educational Tool.

OBJECTIVE: To evaluate the utility of a web-based advocacy training tool in increasing advocacy awareness. METHODS: Early career rheumatologists who attended 2019 American College of Rheumatology Advocacy 101 were invited to participate. A web-based tool consisting of 9 cases covering various aspects of advocacy was developed and included the opportunity for continuing medical education credit. A preparticipation questionnaire surveyed prior involvement, knowledge, and willingness to participate in an advocacy program. Participants rated cases based on educational quality, relevance of content, achievement of training goals, competency, and evidence of bias. Two web-based conferences were held to address technical questions, review, and discussion of cases and responses, and to obtain feedback. RESULTS: Twenty-one early career rheumatologists from 9 academic institutions enrolled, with 15 (75%) completing all cases. Correct continuing medical education answers were scored on 85% of cases. Overall educational quality of content received a mean rating of 4.3 of 5. Seven cases achieved positive ratings for relevance of case content, achievement of training goals, objectivity, and competency. All cases were assessed free of bias. Feedback indicated that 30 minutes were dedicated to each case, and that a combination of skill set and content learning were most effective. Pre- and postquestionnaire scores indicated significant improvement in knowledge of advocacy matters (P < 0.0001). CONCLUSION: A web-based advocacy training tool was successful in significantly improving awareness and knowledge of advocacy matters among early career rheumatologists. This innovative educational tool may play a vital role in shaping the future of rheumatology for both patients and physicians.

Data-Driven Patient Clustering and Differential Clinical Outcomes in the Brigham and Women's Rheumatoid Arthritis Sequential Study Registry.

OBJECTIVE: To use unbiased, data-driven, principal component (PC) and cluster analysis to identify patient phenotypes of rheumatoid arthritis (RA) that might exhibit distinct trajectories of disease progression, response to treatment, and risk for adverse events. METHODS: Patient demographic, socioeconomic, health, and disease characteristics recorded at entry into a large, single-center, prospective observational registry cohort, the Brigham and Women's Rheumatoid Arthritis Sequential Study (BRASS), were harmonized using PC analysis to reduce dimensionality and collinearity. The number of PCs was established by eigenvalue >1, cumulative variance, and interpretability. The resulting PCs were used to cluster patients using a K-means approach. Longitudinal clinical outcomes were compared between the clusters over 2 years. RESULTS: Analysis of 142 variables from 1,443 patients identified 41 PCs that accounted for 77% of the cumulative variance in the data set. Cluster analysis distinguished 5 patient clusters: 1) less RA disease activity/multimorbidity, shorter RA duration, lower incidence of comorbidities; 2) less RA disease activity/multimorbidity, longer RA duration, more infections, psychiatric comorbidities, health care utilization; 3) moderate RA disease activity/multimorbidity, more neurologic comorbidity; 4) more RA disease activity/multimorbidity, shorter RA duration, more metabolic comorbidity, higher body mass index; 5) more RA disease activity/multimorbidity, longer RA duration, more hepatic, orthopedic comorbidity and RA-related surgeries. The clusters exhibited differences in clinical outcomes over 2 years of follow-up. CONCLUSION: Data-driven analysis of the BRASS registry identified 5 distinct phenotypes of RA. These results illustrate the potential of data-driven patient profiling as a tool to support personalized medicine in RA. Validation in an independent data set is ongoing.

Understanding differences between men and women with axial spondyloarthritis.

Axial spondyloarthritis (axSpA) is a chronic inflammatory immune-mediated disease resulting in inflammatory low back pain and other inflammatory manifestations in peripheral joints and entheses. AxSpA encompasses both ankylosing spondylitis (AS), in which patients present with definitive sacroiliitis visible on radiographic imaging, as well as nonradiographic axSpA (nr-axSpA), in which such changes may not be discernable. Emerging evidence suggests that women and men experience axSpA differently. Although the prevalence of AS is approximately 2- to 3- fold higher in men than in women, nr-axSpA occurs with roughly equal frequency in women and men. The goal of this review is to increase awareness of sex differences in axSpA by exploring the distinct manifestations of disease and disease characteristics in women, the overall clinical burden, recommendations for diagnosis, and potential treatment options. We summarize and contextualize the results of recent studies that illuminate sex differences in nr-axSpA and AS, including differences in disease manifestation and progression. It is important that sex differences in axSpA are understood and considered when diagnosing and treating the spectrum of axSpA, including AS and nr-axSpA.

The potential impact of monitoring disease activity biomarkers on rheumatoid arthritis outcomes and costs.

Rheumatoid arthritis (RA) management requires monitoring of disease activity to determine course of treatment. Global assessments are used in clinical practice to determine RA disease activity. Monitoring disease activity via biomarkers may also help providers optimize biologic and nonbiologic drug use while decreasing overall drug spend by delaying use of expensive biologic therapies. By testing multiple biologic domains at the same time, a multibiomarker disease activity test may have utility in RA patient management, through improved intra- and inter-rater reliability. This report provides a comprehensive review of studies of objective measures, single biomarkers and multibiomarker disease activity tests as disease activity measures to decrease uncertainty in treatment decisions, and of biomarkers' potential impact on economic and clinical outcomes of treatment choices.

Inflammation-Triggered Cancer Immunotherapy by Programmed Delivery of CpG and Anti-PD1 Antibody.

Inflammation-triggered combination delivery of anti-PD-1 antibody and CpG oligodeoxynucleotides (CpG ODNs) has been demonstrated to prevent cancer relapse utilizing postsurgical inflammatory response. The controlled release of anti-PD1 and CpG ODN by CpG DNA-based "nano-cocoons" can induce considerable immune response, which in turn significantly prolongs the survival time of mice.

Hypoxia-Sensitive Materials for Biomedical Applications.

Hypoxia is a typical hallmark of various diseases, including cancer, ischemic diseases, and stroke. It is also associated with the disease progression. Therefore, it is critical to develop an effective strategy to target the hypoxic region for diagnosis and treatment. In this review, we summarize recent progress in the development of hypoxia-responsive systems for imaging, sensing and therapy. Two types of hypoxia-sensitive systems, the hypoxia inducible factor-1 based systems and bioreductive molecule based systems, were reviewed with comments on their advantages and limitations. Future opportunities and challenges are also discussed in the end.
