Recent developments for new investigational JAK inhibitors in psoriatic arthritis

ABSTRACT Introduction Psoriatic arthritis (PsA) is a chronic inflammatory disease affecting about one-third of subjects with psoriasis. Several treatment modalities targeting Janus Kinase pathways and intracellular inflammatory cascade are now available and under clinical investigation to treat this disease. Areas covered This review describes ongoing and recently completed phase 2 and 3 randomized clinical trials (RCTs) evaluating the efficacy and safety of approved JAK (Tofacitinib and Upadacitinib) and investigational JAK inhibitors (JAK1 inhibitors: Filgotinib and Ivarmacitinib (SHR0302); TYK2 inhibitors: Brepocitinib (PF-06700841) Deucravacitinib (BMS-986165), and NDI-034858) in PsA through February 2023. Expert opinion Current standard of care has significantly improved the quality of life in PsA. Recently approved JAK inhibitors for PsA have addressed many of the unmet needs of PsA, particularly of those with severe phenotypes. Preliminary results from several RCTs have reported good and fast efficacy and an acceptable safety profile of investigational JAK inhibitors in PsA. Additional clinical trials and long-term outcome data on these agents are necessary for increasing available therapeutic options for PsA.

Associations of Polypharmacy With Clinical Parameters, Function, and Health-Related Quality of Life in Psoriatic Arthritis.

The aim of this study was to assess predictors of polypharmacy and its effect on health-related quality of life in patients with psoriatic arthritis (PsA). This cross-sectional study was performed between February and December 2019. The number of medications was grouped into minor (2-4) and major (≥5) polypharmacy. Functional status and quality of life were assessed using the Health Assessment Questionnaire and Short-Form 36, respectively. Clinical and demographic characteristics, physical function, and quality of life of the polypharmacy group were compared. Predictive factors for major polypharmacy were evaluated using a logistic regression analysis. The mean age of the 100 patients (70 females and 30 males) with PsA was 48.43 ± 12.94 years. The proportion of patients with major polypharmacy was 19%. The physical function subscale of Short-Form 36 was lower in the major polypharmacy group ( p = 0.009). Univariable analysis revealed that sex, body mass index, disease duration, disease activity, psoriasis severity, dactylitis, enthesitis, PsA subtypes, smoking, and Health Assessment Questionnaire were not associated with major polypharmacy ( p > 0.10). In the multivariable model, the number of comorbidities (odds ratio, 3.151; 95% confidence interval, 1.828-5.429; p < 0.001) and age ≥60 years (odds ratio, 4.864; 95% confidence interval, 1.159-20.418; p = 0.031) were significantly associated with major polypharmacy. The number of comorbid diseases and age ≥60 years were the factors associated with major polypharmacy in patients with PsA. Although physical function was not associated with polypharmacy, patients with major polypharmacy had poorer quality of life.

Itch as Major Mediator of Effect of Tofacitinib on Health-Related Quality of Life in Psoriatic Arthritis: A Mediation Analysis.

Patients with psoriatic arthritis (PsA) experience impaired health-related quality of life (HRQoL). Tofacitinib is an oral Janus kinase inhibitor for the treatment of PsA, which has been associated with improvements in dermatologic endpoints in patients with PsA. To assess the extent to which tofacitinib affects patient HRQoL via improvements in dermatologic symptoms, including itch, data were pooled from patients with PsA who received tofacitinib in phase III studies (NCT01866668 and NCT01882439). Mediation modeling assessed the indirect effects (via Itch Severity Item [ISI] and Physician’s Global Assessment of Psoriasis [PGA-PsO]) and direct effects (via all other factors) of tofacitinib treatment on dermatology-specific HRQoL (measured by Dermatology Life Quality Index [DLQI]). In the initial model, the treatment effect on DLQI was largely mediated by itch (ISI; p < 0.0001) and PGA-PsO (p < 0.01). The model was re-specified to assess the indirect effects only of itch and PGA-PsO on DLQI. Here, 17.7% of the treatment effect on DLQI was attributable to PGA-PsO (p = 0.0006), and 82.3% to itch (p < 0.0001). Tofacitinib-dependent improvements in DLQI were primarily mediated by itch relief, in addition to improvements in PGA-PsO.

Health-Related Quality of Life in Psoriatic Arthritis: Findings and Implications

ObjectivesTo assess the quality of life (QOL) and its associated factors in patients with psoriatic arthritis (PsA) who would start treatment with biologic drugs at the Brazilian Unified Health System. MethodsA cross-sectional study was performed at a single center pharmacy in Belo Horizonte, State of Minas Gerais, Brazil. EQ-5D was used to assess the patients’ QOL. The functional status was assessed using the Health Assessment Questionnaire-Disability Index, whereas disease activity was evaluated through the Bath Ankylosing Spondylitis Disease Activity Index and the Clinical Disease Activity Index. Simple and multiple linear regression analyses were performed to assess the factors associated with QOL. ResultsA total of 212 patients with PsA were included, of which 185 (87.3%) reported having some pain/discomfort, and 148 (69.8%) presented some level of anxiety/depression. Patients with PsA had a mean QOL score of 0.651 (SD 0.12) with a significant reduction in female patients, concomitant use of nonsteroidal anti-inflammatory drugs, comorbidity, and worse clinical and functional status. Poor QOL was associated with worse functional status by the Health Assessment Questionnaire-Disability Index, disease activity by the Bath Ankylosing Spondylitis Disease Activity Index, and with diagnoses of osteoporosis, hypothyroidism, and depression. ConclusionPsA and its associated comorbidities negatively affect the QOL, evidencing the need for a comprehensive and effective clinical approach.

P264 Burden of disease and relative impact of skin and joint disease on quality of life in PsA: analysis from a UK secondary care cohort

Abstract Background Understanding the impact of psoriatic arthritis (PsA) on an individual and how the disease evolves over time is important when determining a therapeutic strategy. However, little is known about the natural course of arthritis, psoriasis, and enthesitis, their relative impact on quality of life and how disease burden in real world cohorts compares to clinical trial populations. We set out to describe the burden of disease and impact on quality of life in an observational UK secondary care cohort. Methods Cross sectional cohorts were selected from the Bath PsA cohort, group one with early disease (within 24 months of diagnosis), groups two and three with established disease (commencing therapy with first or second line biologic Disease Modifying Anti-Rheumatic Drug- bDMARD therapy respectively; assessments both at initiation and 3 months after initiation). Results Analyses were undertaken where sufficient data was available on 154 patients eligible for entry into the early PsA cohort (group 1), 240 patients eligible for the biologic initiator cohort (group 2) and 103 for the second line biologics initiator cohort. Cohort characteristics are reported in Table 1. The burden of joint disease was high in all cohorts and approximately comparable to clinical trial populations in group 2 commencing bDMARD (mean tender joints count 22 (SD 14), swollen 7 (SD 5) cDAPSA mean 36 (SD 15)). Mean Body Mass Index (BMI) rose from overweight in early disease to obese in established disease (table 1). There was little enthesitis in any group (LEI mean &amp;lt;1). There was a significant burden of joint disease (cDAPSA), fatigue (FACT) and work disability among those 3 months post commencing bDMARD despite good clinical responses (table 1). The level of skin (PASI) and nail disease (Bath Nail score) was low but remains strongly associated with worse quality of life and the association was stronger in established disease. Conclusion We report high levels of residual joint disease, fatigue, obesity and work disability in both early and established PsA cohorts. Despite low absolute levels of residual skin and nail disease both become more strongly associated with worse quality of life in more established disease. Disclosures W.

Evidence for Psoriatic Arthritis Impact of Disease (PsAID12) as Core Instrument to Measure Health-Related Quality of Life in Psoriatic Arthritis: A Systematic Review of Psychometric Properties

Objective:To evaluate and update the evidence for the measurement properties of the Psoriatic Arthritis Impact of Disease (PsAID12) questionnaire to measure health-related quality of life (HRQoL) in psoriatic arthritis (PsA).Methods:The PsAID12 psychometric evidence was gathered in a systematic literature review in PsA (registration number: CRD42016032546). The study quality was appraised using the Consensus-based Standards for the selection of health Measurement Instruments–Outcome Measures in Rheumatology (COSMIN-OMERACT) good methods check-list. Content validity, test–retest reliability, construct validity, longitudinal construct validity, discrimination, and thresholds of meaning were appraised. Additional analyses for construct validity, responsiveness, and sensitivity to change were conducted in available observational data sets after prespecified hypotheses were formulated.Results:Eight publications (129-474 patients) were analyzed. The PsAID12 fulfilled OMERACT criteria for content validity (patients and physicians endorsed content match with PsA HRQoL domain), feasibility (endorsed by patients and physicians), and test–retest reliability (intraclass correlation coefficient: 0.91-0.95). A priori construct validity hypotheses were mostly met: Psoriatic Arthritis Impact of Disease had high correlation with generic ( r = 0.76-0.87) and PsA-specific HRQol measures (0.8), and with measures of physical function (0.66-0.72), work productivity (0.69-0.75), pain (0.83), and fatigue (0.84). Psoriatic Arthritis Impact of Disease had moderate-high correlation with measures of patient global (0.49-0.84) and dermatologic HRQoL (0.36-0.53). Correlations were higher with generic HRQoL measured by short form-36 physical component score (0.47-0.73) versus short form-36 mental component score (0.22-0.60). Three studies confirmed known group validity of PsAID12 according to PsA disease activity. Psoriatic Arthritis Impact of Disease discriminated between change groups in 2 longitudinal studies (standardized response mean: 0.74-0.91, 53 and 105 patients). The minimal clinically important improvement was 3 and 1.4 points.Conclusion:Psoriatic Arthritis Impact of Disease had evidence for good content and construct validity, reliability, and longitudinal construct validity and is ready to evaluate in clinical trials.

Enthesitis and its relationship with disease activity, functional status, and quality of life in psoriatic arthritis: a multi-center study.

Psoriatic arthritis (PsA) is an inflammatory arthritis with distinct phenotypic subtypes. Enthesitis is assigned as a hallmark of the disease, given its significant relations to disease activity and quality of life. Our objective is to evaluate the prevalence of enthesitis and its association with some clinical parameters, particularly quality of life, using data from a national registry. Patients with PsA meeting ClASsification criteria for Psoriatic Arthritis (CASPAR) were enrolled by means of a multi-centre Turkish League Against Rheumatism (TLAR) Network Project. The following information was recorded in web-based case report forms: demographic, clinical and radiographic data; physical examination findings, including tender and swollen joint counts (TJC and SJC);nail and skin involvement; Disease Activity Score-28 for Rheumatoid Arthritis with Erythrocyte Sedimentation Rate (DAS 28-ESR); Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); Maastricht Ankylosing Spondylitis EnthesitisScore(MASES); Psoriasis Area Severity Index (PASI); Bath Ankylosing Spondylitis Radiology Index for the spine (BASRI-s); Health Assessment Questionnaire (HAQ); Bath Ankylosing Spondylitis Functional Index (BASFI); Health Assessment Questionnaire for the spondyloarthropathies (HAQ-s); Psoriatic arthritis quality of Life scale (PsAQoL); Short Form 36 (SF-36); Hospital Anxiety Depression Scale (HADS); Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F); andFibromyalgiaRapid Screening Tool(FiRST) scores. The patients were divided into two groups, namely with and without enthesitis, based on the triple Likert-type physician-reported statement of 'active enthesitis', 'history of enthesitis' or 'none' in the case report forms. Patients with active enthesitis were compared to others in terms of these clinical parameters. A total of 1130 patients were enrolled in this observational study. Of these patients, 251 (22.2%) had active enthesitis according to the clinical assessment.TJC, HAQ-s, BASDAI, FiRST and PsAQoL were significantly higher whereas the SF-36 scores were lower in patients with enthesitis (p < 0.05). Chronic back pain, dactylitis, and tenosynovitis were more frequent in the enthesopathy group (59.4%/39%, 13.1%/6.5% and 24.7%/3.4%, respectively). Significant positive correlations between the MASES score and the TJC, HAQ, DAS 28-ESR, BASDAI, FiRST and PsAQoL scores, and a negative correlation with the SF-36 score were found. When linear regression analysis was performed, the SF-36 MCS and PCS scores decreased by -9.740 and -11.795 units, and the FiRST scores increased by 1.223 units in patients with enthesitis. Enthesitis is an important involvement of PsA with significant relations to quality of life determined with PsAQoL and SF-36 scores. Our study found higher frequency of dactylitis and chronic back pain, and worse quality of life determined with SF-36 and PsAQoL scores in patients with enthesitis.

Association Between Comorbidities and Quality of Life in Psoriatic Arthritis: Results from a Multicentric Cross-sectional Study.

In psoriatic arthritis (PsA), comorbidities add to the burden of disease, which may lead to poorer quality of life. The purpose of this study was to evaluate the relationship between comorbidities and quality of life (QOL). Patients from a multicentric, cross-sectional study on comorbidities in PsA were included in the analysis. Data on comorbidities were collected and were subsequently used to compute the modified Rheumatic Disease Comorbidity Index (mRDCI). The Medical Outcomes Study Short Form-36 questionnaire physical (PCS) and mental component summary (MCS) scales were used to assess QOL. In total, 124 recruited patients fulfilled the ClASsification for Psoriatic ARthritis criteria (CASPAR): 62.1% were male; mean age and mean disease duration were 52.6 ± 12.6 years and 11.3 ± 9.6 years, respectively. The number of comorbid conditions was 2.0 ± 1.3, with 30.6% of the sample having currently or a history of 3 or more comorbidities. In the multivariate linear regression analysis, only anxiety remained significantly related to mental health (p < 0.0001). Anxiety alone accounted for 28.7% of the variance in MCS scores. Moreover, MCS was also significantly associated with the mRDCI score, which explained 4.9% of the variance in MCS [β = -1.56 (standard error 0.64), R2 = 0.049, p = 0.0167]. In contrast, PCS was not significantly associated either with type or number of comorbidities. In this study, the type of comorbidity appeared to have a greater effect than the number of comorbidities. Indeed, anxiety in PsA was independently associated with QOL and would thus be an important factor to take into account in daily clinical practice.

The GRAPPA-OMERACT Psoriatic Arthritis Working Group at the 2018 Annual Meeting: Report and Plan for Completing the Core Outcome Measurement Set.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) Psoriatic Arthritis (PsA) Working Group reported at the 2018 GRAPPA annual meeting on the outcome of the OMERACT 2018 Conference in Terrigal, Australia. The working group presented the endorsement of the 66/68 joint count for the assessment of peripheral arthritis and the provisional endorsement of the PsA Impact of Disease 12 questionnaire for the assessment of PsA-specific health-related quality of life in PsA randomized controlled trials and observational studies. In this report, the group presents its plan to seek OMERACT endorsement for outcome measures that address the domains of MSK disease activity for enthesitis and dactylitis, physical function, fatigue, and structural damage following the OMERACT Filter 2.1 methodology.

Psoriatic arthritis epidemiology

Recent studies have added to our knowledge of the epidemiology of psoriatic arthritis (PsA) across various populations. Absence of a standard case definition and the relative rarity of PsA may have contributed to the paucity of available data to date. Reported prevalence estimates appear to vary more than incidence estimates. Prevalence estimates may vary as a result of differences in genetic factors, exposure to environmental factors, and study methods. Although prevalence data among different subgroups and extrapolation from clinical and laboratory data allow some inferences about the role of various potential risk factors for PsA, only one study has investigated them specifically. Overall, quality of life in PsA appears similar to that in rheumatoid arthritis, whereas available data on the mortality impact of PsA are conflicting, preventing a unified conclusion. This review summarizes recent data on PsA epidemiology.
