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 NCT0188243 ...[more]

Project description:ObjectivePost hoc analysis of pooled data from nine randomised controlled trials to assess the effect of tofacitinib (oral Janus kinase inhibitor for treatment of rheumatoid arthritis (RA) and psoriatic arthritis (PsA)) on residual pain in patients with RA or PsA with abrogated inflammation.MethodsPatients who received ≥1 dose of tofacitinib 5 mg twice daily, adalimumab or placebo with/without background conventional synthetic disease-modifying antirheumatic drugs and had abrogated inflammation (swollen joint count (SJC)=0 and C reactive protein (CRP)<6 mg/L) after 3 months' therapy were included. Assessments included Patient's Assessment of Arthritis Pain at month 3 (Visual Analogue Scale [VAS] 0-100 mm). Scores were summarised descriptively; treatment comparisons assessed by Bayesian network meta-analyses (BNMA).ResultsFrom the total population with RA/PsA, 14.9% (382 of 2568), 17.1% (118 of 691) and 5.5% (50 of 909) of patients receiving tofacitinib, adalimumab and placebo, respectively, had abrogated inflammation after 3 months' therapy. Patients with RA/PsA with abrogated inflammation receiving tofacitinib/adalimumab had higher baseline CRP versus placebo; patients with RA receiving tofacitinib/adalimumab had lower SJC and longer disease duration versus placebo. Median residual pain (VAS) at month 3 was 17.0, 19.0 and 33.5 in patients with RA treated with tofacitinib, adalimumab or placebo, and 24.0, 21.0 and 27.0 in patients with PsA, respectively. Residual pain reductions with tofacitinib/adalimumab versus placebo were less prominent in patients with PsA versus patients with RA, with no significant differences between tofacitinib/adalimumab, per BNMA.ConclusionPatients with RA/PsA with abrogated inflammation receiving tofacitinib/adalimumab had greater residual pain reduction versus placebo at month 3. Results were similar between tofacitinib and adalimumab.Trial registration numberClinicalTrials.gov registry (NCT00960440; NCT00847613; NCT00814307; NCT00856544; NCT00853385; NCT01039688; NCT02187055; NCT01877668; NCT01882439).

Project description:BackgroundPsoriatic arthritis (PsA) is a chronic, systemic immune-mediated inflammatory musculoskeletal disease. The onset of dermatologic symptoms often precedes rheumatic manifestations. Tofacitinib is an oral Janus kinase inhibitor for the treatment of PsA that has been shown to improve dermatologic symptoms in patients with PsA.ObjectivesTo investigate the efficacy of tofacitinib in improving dermatologic endpoints in adult patients with active PsA.MethodsThis analysis included data from two placebo-controlled, double-blind, phase 3 studies in patients with active PsA and an inadequate response (IR) to ≥1 conventional synthetic disease-modifying antirheumatic drug (csDMARD) who were tumor necrosis factor inhibitor (TNFi)-naïve (OPAL Broaden; NCT01877668) or an IR to ≥1 TNFi (OPAL Beyond; NCT01882439). Patients had active plaque psoriasis at screening and received a stable dose of one csDMARD during the study. Patients were randomized to tofacitinib 5 mg twice daily (BID), 10 mg BID, adalimumab 40 mg subcutaneous injection once every 2 weeks (OPAL Broaden only) or placebo (to Month 3). Dermatologic endpoints: Psoriasis Area and Severity Index (PASI) total score; PASI90 overall; PASI75 and PASI90 by baseline PASI severity; Physician's Global Assessment of Psoriasis; Nail Psoriasis Severity Index; Dermatology Life Quality Index total and sub-dimension scores; Itch Severity Item; and Patient's Global Joint and Skin Assessment-Visual Analog Scale-Psoriasis question.ResultsIn patients with active PsA, including those stratified by mild or moderate/severe dermatologic symptoms, greater improvements from baseline and percentage of responders were observed in tofacitinib-treated patients vs. placebo for the majority of analyzed dermatologic endpoints at Months 1 and 3, and improvements were maintained to Month 12 in OPAL Broaden and Month 6 in OPAL Beyond. Similar effects were observed in adalimumab-treated patients vs. placebo in OPAL Broaden across dermatologic endpoints.ConclusionsTofacitinib provides a treatment option for patients with active PsA, including the burdensome dermatologic symptoms of PsA.

Project description:ObjectiveTofacitinib is an oral Janus kinase inhibitor for the treatment of psoriatic arthritis (PsA). This analysis characterized the pharmacokinetics (PK) of tofacitinib in adult patients with active PsA and evaluated the impact of covariates (baseline characteristics) on the disposition of tofacitinib.Materials and methodsData were pooled from two phase 3 studies of tofacitinib of up to 12 months' duration in patients with active PsA (OPAL Broaden (NCT01877668); OPAL Beyond (NCT01882439)). This analysis included 650 tofacitinib-treated patients with 3,252 tofacitinib plasma concentration measurements. Tofacitinib PK was described using a one-compartment disposition model parameterized in terms of apparent oral clearance (CL/F) and apparent volume of distribution (V/F) with first-order absorption rate (Ka) and a lag time. Covariates evaluated were baseline age, baseline body weight, sex, race, ethnicity, baseline creatinine clearance (BCCL), and baseline C-reactive protein.ResultsThe estimates (95% confidence interval) of PK model parameters of a reference patient were CL/F: 20.4 (18.6, 21.8) L/h; V/F: 110 (108, 113) L; and Ka: 13.8 (12.1, 16.6)/h. Among the covariates, only BCCL led to clinically relevant changes in exposure; however, this was consistent with the known contribution of renal excretion to the total clearance of tofacitinib (~ 30%).ConclusionTofacitinib did not require dose modification or restrictions for age, body weight, sex, race, ethnicity, or baseline disease severity in patients with active PsA based on the magnitude of exposure relative to a reference patient. Dosing adjustments for renal impairment were derived from a separate phase 1 study.

Project description:IntroductionPain is a multidimensional factor and core domain of psoriatic arthritis (PsA). This analysis aimed to quantify the role of potential inflammation-associated outcomes on pain reduction in patients with PsA receiving tofacitinib, using mediation modeling.MethodsPooled data were from two phase 3 studies (OPAL Broaden and OPAL Beyond) of patients with active PsA treated with tofacitinib 5 mg twice daily or placebo. Mediation modeling was utilized to quantify the indirect effects (via Itch Severity Item [ISI], C-reactive protein [CRP] levels, swollen joint count [SJC], Psoriasis Area and Severity Index [PASI], and enthesitis [using Leeds Enthesitis Index]) and direct effects (representing all other factors) of tofacitinib treatment on pain improvement.ResultsThe initial model showed that tofacitinib treatment affects pain, primarily indirectly, via ISI, CRP, SJC, PASI, and enthesitis (overall 84.0%; P = 0.0009), with 16.0% (P = 0.5274) attributable to the direct effect. The model was respecified to exclude SJC and PASI. Analysis of the final model revealed that 29.5% (P = 0.0579) of tofacitinib treatment effect on pain was attributable to the direct effect, and 70.5% (P < 0.0001) was attributable to the indirect effect. ISI, CRP, and enthesitis mediated 37.4% (P = 0.0002), 15.3% (P = 0.0107), and 17.8% (P = 0.0157) of the tofacitinib treatment effect on pain, respectively.ConclusionsThe majority of the effect of tofacitinib on pain was collectively mediated by itch, CRP, and enthesitis, with itch being the primary mediator of treatment effect.Trial registrationNCT01877668, NCT01882439.

Project description:BackgroundPsoriatic arthritis (PsA) is a chronic inflammatory condition that can affect individuals of all ages. Patients may experience a range of physical and psychological issues.ObjectiveTo examine the impact of PsA on an individual's quality of life (QoL) and physical function.DesignA systematic review of the literature.Data sources and methodsA comprehensive search was conducted across seven electronic databases (Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, AMED, EMBASE, Global Health, MEDLINE and PsycINFO) to retrieve articles related to QoL and lifestyle in adults with PsA. The inclusion criteria were studies published between 2010 and 2021 that used outcomes validated in patients with PsA. The methodological quality was assessed using Joanna Briggs Institute Critical Appraisal Tools. Our primary outcomes were patient-reported outcomes (PROs) measuring QoL and the impact of disease on physical function. The secondary outcomes were assessments of fatigue, anxiety, depression, sleep, work productivity and employment.ResultsThe study included 37 comprehensive studies that examined the impact of PsA on QoL and physical function. The findings revealed that the impact of PsA extends to various aspects of life, including activities of daily living, physical, and emotional aspects, such as fatigue, sleep disturbance, anxiety and depression. Notably, people with PsA experience reduced health-related quality of life (HRQoL), particularly in emotional, social and mental health aspects. The severity of pain and/or fatigue is directly linked to decreased HRQoL. Importantly, those who fail to achieve minimal disease activity face challenges in work productivity and employment status.ConclusionTo conclude, our review underscores the significant impact of PsA on patients' HRQoL beyond joint disease. The emotional, social, and mental aspects of PsA require compassionate and holistic management.Trial registrationThe PROSPERO international prospective register of systematic reviews - CRD42021257395.

Project description:OBJECTIVE:To examine the effects of filgotinib, an oral, selective Janus kinase 1 inhibitor, on health-related quality of life (HRQoL) using the Psoriatic Arthritis Impact of Disease (PsAID)9 questionnaire in active PsA. METHODS:Patients were randomized 1 : 1 to filgotinib 200 mg or placebo once daily for 16 weeks in EQUATOR, a multicentre, double-blind, phase 2 randomized controlled trial. HRQoL was assessed with PsAID9 at Weeks 4 and 16. Change from baseline in total and individual domain scores, plus the proportions of patients achieving minimal clinically important improvement (MCII; ⩾3 points) and patient-accepted symptom status (PASS; score <4), were evaluated. Correlation with the 36-item short-form health survey (SF-36) was investigated. RESULTS:One hundred and thirty-one patients were randomized to filgotinib or placebo. Filgotinib effects on PsAID9 were observed from Week 4. At Week 16, mean (s.d.) change from baseline in PsAID9 was -2.3 (1.8) and -0.8 (2.2) for filgotinib and placebo, respectively (least-squares mean of group difference -1.48 [95% CI -2.12, -0.84], P < 0.0001), with significant improvements in all domains vs placebo. Significantly more patients on filgotinib achieved MCII (group difference 25.4% [95% CI 8.92, 39.99], P = 0.0022) and PASS (group difference 29.6% [95% CI 10.65, 45.60], P = 0.0018) at Week 16 vs placebo. Similar improvements in SF-36 were observed, with moderate to strong negative correlation between PsAID9 and SF-36. CONCLUSION:Filgotinib significantly improved HRQoL vs placebo in patients with active PsA, as measured by PsAID9. To our knowledge, EQUATOR is the first randomized controlled trial to evaluate PsAID9. TRIAL REGISTRATION:ClinicalTrials.gov, https://clinicaltrials.gov/ct2/show, NCT03101670.

Project description:IntroductionRisk of herpes zoster (HZ) is increased with Janus kinase inhibitor use. We evaluated clinical study data relating to HZ management in patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) receiving tofacitinib.MethodsThis post hoc analysis included data from 21 RA and 3 PsA clinical studies; data were pooled for tofacitinib doses. Outcomes of HZ events (serious and non-serious) and tofacitinib treatment changes were evaluated in response to first and second HZ events. Median time to resolution was stratified by dermatomal involvement, history of HZ prior to tofacitinib, changes to tofacitinib treatment, anti-viral and corticosteroid use, and tofacitinib dose.ResultsSeven hundred eighty-three (11.1%, N = 7061) patients with RA experienced ≥ 1 HZ event, 63 (8.0%) of whom had ≥ 2 HZ events. In patients with PsA, 36 (4.6%, N = 783) experienced ≥ 1 HZ event, 1 (2.8%) of whom had ≥ 2 HZ events. For most HZ events, tofacitinib treatment was unchanged or temporarily discontinued. The majority of patients received anti-viral treatment, most within 3 days of onset. Post-herpetic neuralgia developed in 6.9% and 3.2% of patients with RA with first and second events, respectively, and in 2.8% of patients with PsA with a first event. Most first and second events resolved (RA: 97.6% and 96.8%, respectively; PsA: 94.4% and 100%, respectively). Median time to resolution was 22.0 days for first and 15.0 days for second events for RA and 20.5 days for first and 11.0 days for second events (n = 1) for PsA. Time to resolution of first events for RA and PsA was generally numerically shorter for patients with single dermatomal HZ, history of HZ, or anti-viral use versus those without.ConclusionAmong patients receiving tofacitinib, recurrent events were more common in patients with RA versus PsA; HZ duration was shorter for repeat events.Trial registrationNCT01262118, NCT01484561, NCT00147498, NCT00413660, NCT00550446, NCT00603512, NCT00687193, NCT01164579, NCT00976599, NCT01059864, NCT01359150, NCT02147587, NCT00960440, NCT00847613, NCT00814307, NCT00856544, NCT00853385, NCT01039688, NCT02187055, NCT00413699, NCT00661661, NCT01877668, NCT01882439, NCT01976364.

Project description:IntroductionPsoriasis (Pso) and psoriatic arthritis (PsA) can reduce the quality of life (QoL) and are known to be associated with depression. Within this study, we aimed to assess the burden of disease, functional capacity, quality of life, and depressive symptoms and identify factors predicting functional impairment and depression in patients with psoriatic disease.MethodsA cross-sectional survey was conducted in a cohort of 300 patients with psoriatic disease including 150 patients from a university hospital dermatology outpatient clinic and 150 patients from a university hospital rheumatology outpatient clinic. Questionnaire-based assessment of signs of arthritis (Psoriasis Epidemiology Screening Tool; PEST), functional status (Functional Questionnaire Hannover; FFbH), quality of life (World Health Organization Quality of Life Brief Version; WHOQOL-BREF), and depressive symptoms (Patient health questionnaire 9; PHQ-9) and retrospective medical chart analysis were performed.ResultsDespite treatment, burden of disease was high. Joint pain was reported in multiple regions in patients with Pso (n = 111) and patients with PsA (n = 189), but with differences in frequency and distribution patterns of symptoms. Functional impairment in everyday life was independently associated with diagnosis of PsA (odds ratio [OR] 9.56, p = 0.005), depressive symptoms (OR 5.44, p < 0.001) and age (OR 1.04, p = 0.033). At least mild depressive symptoms were demonstrated in 54% and 69% of patients with Pso and PsA, respectively. In a logistic regression model, depressive symptoms were independently associated with functional impairment (OR 4.50, p = 0.003), axial complaints (OR 2.80, p = 0.030), diagnosis of psoriatic arthritis (OR 2.69, p = 0.046), and number of joint regions with complaints (OR 1.10, p = 0.032).ConclusionFunctional impairment, QoL, and depressive symptoms are mutually interdependent. Early diagnosis of PsA and initiation of anti-inflammatory therapy are essential to avoid long-term damage, disability, and mental health complications. However, despite therapy many patients with PsA, and especially female patients, report a substantial residual disease burden due to their psoriatic disease which will need to be addressed by a more patient-centered approach.

Project description:ObjectivesTo determine the effects of biological disease-modifying anti-rheumatic drugs (bDMARDs) on the quality of life (QoL) among patients with psoriatic arthritis (PsA).DesignMeta-analysis.Data sources and eligibility criteriaPubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure, WanFang and VIP databases were searched to collect randomised controlled trials (RCTs), which were conducted to evaluate the effect of bDMARDs in the treatment of patients with PsA and reported QoL-related outcomes, from inception to November 2020 and updated on 19 February 2022.Data extraction and synthesisOutcomes about Health Assessment Questionnaire Disability Index (HAQ-DI), Dermatology Life Quality Index, physical component summary and mental component summary of the Short Form 36, EuroQol Visual Analogue Scale, Psoriasis Area Severity Index (PASI) 50/75/90/100 were extracted by two reviewers independently. Data were pooled using the fixed or random effects methods and considered as mean difference (MD) or risk ratio with 95% CI.ResultsOut of 3190 articles screened, 37 RCTs (with 47 articles reported) were included. Pooled estimates showed that bDMARDs were superior versus placebo on all outcomes. Against methotrexate (MTX) and tofacitinib, bDMARDs showed no statistically significant advantages or significant disadvantages. Similar results were found for bDMARDs+MTX versus MTX. For HAQ-DI, the results of the subgroups of bDMARDs versus placebo, bDMARDs+MTX versus MTX, bDMARDs versus tofacitinib and bDMARDs versus MTX were -0.21 (MD, 95% CI, -0.23 to -0.18), -0.22 (MD, 95% CI, -0.58 to 0.14), -0.01 (MD, 95% CI, -0.05 to 0.04) and -0.03 (MD, 95% CI, -0.04 to -0.02), respectively.ConclusionsCompared with placebo, bDMARDs taken by patients with PsA appear to significantly improve the QoL. Compared with other therapeutic agents, more studies are required to confirm the effect of single and combined bDMARDs use further.

Project description:IntroductionThe safety of tofacitinib in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) has been demonstrated in clinical studies of ≤ 4 and 9.5 years, respectively. Post-marketing surveillance (PMS) data for tofacitinib from spontaneous and voluntary adverse event (AE) reports have been published for RA, but not PsA. To inform the real-world safety profile of tofacitinib in PsA, we evaluated AE reports submitted to the Pfizer safety database (including RA data for context).MethodsEndpoints included AEs, serious AEs (SAEs), AEs of special interest (AESIs; serious infections, herpes zoster, cardiovascular events, malignancies, venous thromboembolism), and fatal cases. Exposure was estimated using IQVIA global commercial sales data. Number, frequency, and reporting rates (RRs; number of events/100 patient-years' [PY] exposure) were summarized by indication and formulation (immediate release [IR] 5 or 10 mg twice daily], modified release [MR] 11 mg once daily, or all tofacitinib). The data-collection period differed by indication (PsA: 14 December 2017 [US approval, IR/MR] to 6 November 2021; RA: 6 November 2012 [US approval, IR] to 6 November 2021; MR approval, 24 February 2016).ResultsA total of 73,525 case reports were reviewed (PsA = 5394/RA = 68,131), with 20,706/439,370 PY (PsA/RA) of exposure. More AEs were reported for IR versus MR (IR/MR: PsA = 8349/7602; RA = 137,476/82,153). RRs for AEs (IR/MR: PsA = 59.6/113.4; RA = 44.0/64.8) and SAEs (PsA = 8.1/13.6; RA = 8.0/9.5) were higher with MR versus IR. AE RRs (RA) in the first 4 years after IR approval were 95.9 (IR; 49,439 PY) and 147.0 (MR; 2000 PY). Frequency of SAEs, AESIs, and fatal cases was mostly similar across formulations and indications. The most frequently-reported AE Preferred Terms (PsA/RA) included drug ineffective (20.0%/17.8%), pain (9.7%/10.6%), condition aggravated (9.9%/10.5%), headache (8.8%/7.9%) and, for PsA, off-label use (10.5%/3.4%).ConclusionsTofacitinib PMS safety data from submitted AE reports were consistent between PsA and RA, and aligned with its known safety profile. Exposure data (lower MR versus IR; estimation from commercial sales data), reporting bias, reporter identity, and regional differences in formulation use limit interpretation.
