RESUMEN
In this commentary, we review clinical data which helps inform individualized benefit-risk assessment for tofacitinib in patients with psoriatic arthritis (PsA) and ankylosing spondylitis (AS). ORAL Surveillance, a safety trial of patients ≥ 50 years of age with rheumatoid arthritis (RA) and cardiovascular risk factors, found increased rates of safety outcomes (including major adverse cardiovascular events [MACE], malignancies excluding non-melanoma skin cancer, and venous thromboembolism) with tofacitinib versus tumor necrosis factor inhibitors (TNFi). Post hoc analyses of ORAL Surveillance have identified subpopulations with different relative risk versus TNFi; higher risk with tofacitinib was confined to patients ≥ 65 years of age and/or long-time current/past smokers, and specifically for MACE, patients with a history of atherosclerotic cardiovascular disease (ASCVD). In patients without these risk factors, risk differences between tofacitinib and TNFi could not be detected. Given differences in demographics, pathophysiology, and comorbidities, we sought to examine whether the risk stratification observed in RA is also appropriate for PsA and AS. Data from the PsA tofacitinib development program show low absolute risk of safety outcomes in patients < 65 years of age and never smokers, and low MACE risk in patients with no history of ASCVD, consistent with results from ORAL Surveillance. No MACE, malignancies, or venous thromboembolism were reported in the tofacitinib AS development program. The mechanism of the ORAL Surveillance safety findings is unknown, and there are no similar prospective studies of sufficient size and duration. Accordingly, it is appropriate to use a precautionary approach and extrapolate differentiating risk factors identified from ORAL Surveillance (age ≥ 65 years, long-time current/past smoking, and history of ASCVD) to PsA and AS. We recommend an individualized approach to treatment decisions based on these readily identifiable risk factors, in line with updated labeling for Janus kinase inhibitors and international guidelines for the treatment of PsA and AS.Trial Registration: NCT02092467, NCT01262118, NCT01484561, NCT00147498, NCT00413660, NCT00550446, NCT00603512, NCT00687193, NCT01164579, NCT00976599, NCT01059864, NCT01359150, NCT02147587, NCT00960440, NCT00847613, NCT00814307, NCT00856544, NCT00853385, NCT01039688, NCT02281552, NCT02187055, NCT02831855, NCT00413699, NCT00661661, NCT01877668, NCT01882439, NCT01976364, NCT00678210, NCT01710046, NCT01241591, NCT01186744, NCT01276639, NCT01309737, NCT01163253, NCT01786668, NCT03502616.
RESUMEN
INTRODUCTION: Randomized controlled trials have demonstrated tofacitinib efficacy for psoriatic arthritis (PsA); however, real-world effectiveness data are limited. This real-world analysis assessed baseline demographics/disease characteristics and tofacitinib effectiveness in patients with PsA in the CorEvitas PsA/Spondyloarthritis Registry. METHODS: This study (NCT05195814) included patients with PsA initiating tofacitinib from December 2017-December 2021, as monotherapy or with oral small molecules (methotrexate/leflunomide/sulfasalazine/apremilast), pre-existing use, or initiated concurrently. OUTCOMES: mean change from baseline in disease activity/patient-reported outcomes, proportion of patients achieving low disease activity (LDA)/remission at 6 ± 3 months, and discontinuation rates. RESULTS: Of 222 patients with PsA who initiated tofacitinib (60.8% as monotherapy), 123 patients had 6 ± 3 months of follow-up. At initiation, 59.7% were female, 92.3% were White, mean age was 56.3 years, PsA duration since diagnosis was 8.2 years, and 25.7% were biologic disease-modifying antirheumatic drug (bDMARD)-naïve. Improvements to 6 ± 3 months were observed with tofacitinib for Clinical Disease Activity Index for PsA (cDAPSA), DAPSA, PsA Disease Activity Score (PASDAS), Clinical Disease Activity Index, body surface area (BSA), tender/swollen joint count, patient fatigue, pain, Patient Global Skin Assessment, and Health Assessment Questionnaire-Disability Index. At 6 ± 3 months, 25.0%/7.8% of patients treated with tofacitinib achieved cDAPSA-defined LDA/remission, 18.2% achieved minimal disease activity, 30.8% had PASDAS ≤ 3.2, 42.9%/29.4% had resolved enthesitis/dactylitis, and 22.5% achieved BSA = 0%. Tofacitinib discontinuation occurred in 51.2% of patients (51.6% of monotherapy initiators) at/prior to 6 ± 3 months (27.6%/23.6%), 57.1% of whom switched to tumor necrosis factor/interleukin-17 inhibitors. Reasons for discontinuation were not reported in 85.3%/79.3% of patients who discontinued at/prior to 6 ± 3 months. CONCLUSIONS: This real-world US cohort analysis described patients with PsA newly initiating tofacitinib; most were bDMARD-experienced or receiving monotherapy treatment. In patients who remained on therapy (48.8%), tofacitinib was effective across multiple PsA domains at 6 ± 3 months. Limitations included small patient numbers at follow-up and potential selection bias. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT05195814.
RESUMEN
OBJECTIVE: To evaluate the efficacy and safety of tofacitinib in patients with ankylosing spondylitis (AS) by prior biologic disease-modifying antirheumatic drug (bDMARD) use. METHODS: Data from a placebo-controlled, double-blind study of patients with active AS were analyzed. Patients received tofacitinib 5 mg twice daily (BID) or placebo to week 16; all received open-label tofacitinib 5 mg BID to week 48 and were stratified by prior treatment (bDMARD-naive or tumor necrosis factor inhibitor [TNFi]-inadequate responder [IR], including bDMARD-experienced [non-IR]). Disease activity/safety were assessed throughout. RESULTS: Of 269 patients, 207 (77%) were bDMARD-naive; 62 (23%) were in the TNFi-IR subgroup. TNFi-IR patients had higher baseline BMI (28.0 vs. 26.1 kg/m2 ), longer symptom duration (14.4 vs. 13.2 years), and lower concomitant conventional synthetic DMARD use (14.5% vs. 30.9%) than bDMARD-naive patients. At week 16, for most outcomes, tofacitinib efficacy exceeded placebo for both subgroups and was sustained to week 48. At week 16, tofacitinib versus placebo differences were similar between bDMARD-naive and TNFi-IR patients (Assessment in Spondyloarthritis international Society 40 treatment difference [95% confidence interval]: 30.8% [19.1%-42.6%] vs. 19.4% [1.7%-37.0%]). Adverse event (AE) proportions were similar between tofacitinib-treated bDMARD-naive/TNFi-IR patients (77.5%/77.4%) at week 48 with no deaths. A numerically higher proportion of tofacitinib-treated TNFi-IR versus bDMARD-naive patients discontinued study drug (12.9% vs. 3.9%) or dose reduced/temporarily discontinued due to AEs (19.4% vs. 11.8%). CONCLUSION: Tofacitinib efficacy exceeded placebo at week 16 for bDMARD-naive/TNFi-IR patients and was sustained to week 48. The absolute magnitude of responses was generally greater in bDMARD-naive patients versus TNFi-IR patients. More TNFi-IR versus bDMARD-naive patients discontinued or dose reduced/temporarily discontinued tofacitinib due to AEs. Small sample size and sample size differences between subgroups limited the interpretation.
RESUMEN
INTRODUCTION: The 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). METHODS: Endpoints 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). RESULTS: A 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%). CONCLUSIONS: Tofacitinib 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.
RESUMEN
INTRODUCTION: This post hoc analysis of phase 2 trial data assessed the efficacy of tofacitinib on magnetic resonance imaging (MRI) outcomes with the detailed anatomy-based Canada-Denmark (CANDEN) MRI scoring system and evaluated tofacitinib suppression of spinal inflammation in patients with active ankylosing spondylitis (AS). METHODS: Patients with active AS (per modified New York criteria) were randomized 1:1:1:1 to receive tofacitinib 2, 5, or 10 mg twice daily (BID), or placebo, in a 16-week, phase 2, double-blind clinical trial. Spine MRI assessments were performed at baseline and week 12. For post hoc analysis, MRI images from patients receiving tofacitinib 5 or 10 mg BID, or placebo, were re-evaluated by two readers blinded to time point/treatment and assessed by the CANDEN MRI scoring system. Least squares mean changes from baseline to week 12 were reported for CANDEN-specific MRI outcomes, with analysis of covariance used for comparisons of pooled tofacitinib and tofacitinib 5 or 10 mg BID versus placebo. p values without multiplicity adjustment were reported. RESULTS: MRI data from 137 patients were analyzed. At week 12, CANDEN spine inflammation score and vertebral body, posterior elements, corner, non-corner, facet joint, and posterolateral inflammation subscores were significantly reduced with pooled tofacitinib versus placebo (p < 0.0001; except non-corner subscore, p < 0.05). Total spine fat score was numerically increased with pooled tofacitinib versus placebo. CONCLUSIONS: In patients with AS, tofacitinib treatment was associated with significant reductions in MRI scores of spinal inflammation versus placebo, as assessed by the CANDEN MRI scoring system. Tofacitinib reduced inflammation in posterolateral elements of the spine and facet joints, which has not been described previously. TRIAL REGISTRATION: ClinicalTrials.gov registry (NCT01786668).
RESUMEN
Background: Tofacitinib is a Janus kinase inhibitor for the treatment of psoriatic arthritis (PsA) and has been investigated for psoriasis (PsO). Objectives: This post hoc analysis examined baseline cardiovascular (CV) disease risk and its association with the occurrence of major adverse cardiovascular events (MACE) and malignancies in tofacitinib-treated patients with PsA and PsO. Design: Included three phase III/long-term extension (LTE) PsA trials and seven phase II/phase III/LTE PsO trials of patients receiving ⩾ 1 dose of tofacitinib. Methods: Incidence rates (IRs: patients with events/100 patient-years) for MACE and malignancies (excluding non-melanoma skin cancer) were determined in subgroups according to history of atherosclerotic CV disease (ASCVD), baseline 10-year risk of ASCVD (in patients without history of ASCVD), and baseline metabolic syndrome (MetS). Results: For patients with PsA (N = 783) and PsO (N = 3663), respectively, tofacitinib exposure was 2038 and 8950 patient-years (median duration: 3.0 and 2.4 years), and 40.9% and 32.7% had MetS. Excluding missing CV risk profile data, 51/773 (6.6%) and 144/3629 (4.0%) patients had history of ASCVD, and in patients without history of ASCVD, around 20.0% had intermediate/high baseline 10-year ASCVD risk. For PsA and PsO, IRs of MACE were greatest in those with history of ASCVD or high baseline 10-year ASCVD risk. For PsA, five of six patients with MACE had baseline MetS. Malignancy IRs in patients with PsA were greatest in those with intermediate/high baseline 10-year ASCVD risk. Of these, eight of nine patients with malignancies had baseline MetS. In the PsO cohort, IR of malignancies was notably greater with high versus low/borderline/intermediate baseline 10-year ASCVD risk. Conclusion: In tofacitinib-treated patients with PsA/PsO, increased ASCVD risk and baseline MetS were associated with higher IRs for MACE and malignancies. Our results support assessing CV risk in patients with PsA/PsO and suggest enhanced cancer monitoring in those with increased ASCVD risk. Registration ClinicalTrialsgov: NCT01877668/NCT01882439/NCT01976364/NCT00678210/NCT01710046/NCT01241591/NCT01186744/NCT01276639/NCT01309737/NCT01163253. Plain Language Summary: People who have psoriatic arthritis or psoriasis may have more heart-related problems and cancer if they have a higher risk of cardiovascular disease: A study in people with psoriatic arthritis or psoriasis receiving tofacitinib Why was this study done? ⢠People with psoriatic arthritis (PsA) and psoriasis (PsO) are more likely than the general population to have a disease affecting the heart and blood vessels [cardiovascular (CV) disease].⢠People who are more likely to have CV disease may also be more likely to have certain types of cancer.⢠Tofacitinib is a medicine to treat people with PsA and has been tested in people with PsO.⢠We wanted to know if the risk of CV disease affects the number of heart-related problems (including heart attack, stroke, or death) and cancer in people with PsA and PsO. What did the researchers do? ⢠We used results from 10 clinical trials.⢠In these trials, people with PsA and PsO were taking tofacitinib 5 or 10 mg twice a day.⢠After the trials had ended, we measured people's risk of CV disease using a risk calculator. This risk calculator showed if they had a low, borderline, intermediate, or high risk of CV disease over the next 10 years. We also checked if they had had CV disease before treatment.⢠We checked if people had a group of conditions linked to CV disease: diabetes, high blood pressure, and obesity.⢠We counted the cases of heart-related problems and cancer in people once they started taking tofacitinib. What did the researchers find? In people with PsA and PsO taking tofacitinib:⢠There were more cases of heart-related problems and cancer in people who had intermediate or high risk of CV disease.⢠There were more cases of heart-related problems in people who had had CV disease before.⢠More people with diabetes, high blood pressure, and obesity had heart-related problems and cancer than people without those conditions. What do the findings mean? ⢠It is important to measure risk and assess history of CV disease in people with PsA and PsO, including those taking tofacitinib.⢠We should test for cancer in people with high risk of CV disease.
RESUMEN
OBJECTIVES: To define the instruments for the Assessment of SpondyloArthritis international Society-Outcomes Measures in Rheumatology (ASAS-OMERACT) core domain set for axial spondyloarthritis (axSpA). METHODS: An international working group representing key stakeholders selected the core outcome instruments following a predefined process: (1) identifying candidate instruments using a systematic literature review; (2) reducing the list of candidate instruments by the working group, (3) assessing the instruments' psychometric properties following OMERACT filter 2.2, (4) selection of the core instruments by the working group and (5) voting and endorsement by ASAS. RESULTS: The updated core set for axSpA includes seven instruments for the domains that are mandatory for all trials: Ankylosing Spondylitis Disease Activity Score and Numerical Rate Scale (NRS) patient global assessment of disease activity, NRS total back pain, average NRS of duration and severity of morning stiffness, NRS fatigue, Bath Ankylosing Spondylitis Function Index and ASAS Health Index. There are 9 additional instruments considered mandatory for disease-modifying antirheumatic drugs (DMARDs) trials: MRI activity Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joints and SPARCC spine, uveitis, inflammatory bowel disease and psoriasis assessed as recommended by ASAS, 44 swollen joint count, Maastricht Ankylosing Spondylitis Enthesitis Score, dactylitis count and modified Stoke Ankylosing Spondylitis Spinal Score. The imaging outcomes are considered mandatory to be included in at least one trial for a drug tested for properties of DMARD. Furthermore, 11 additional instruments were also endorsed by ASAS, which can be used in axSpA trials on top of the core instruments. CONCLUSIONS: The selection of the instruments for the ASAS-OMERACT core domain set completes the update of the core outcome set for axSpA, which should be used in all trials.

INTRODUCTION: Pain 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. METHODS: Pooled 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. RESULTS: The 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. CONCLUSIONS: The 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.

RESUMEN
BACKGROUND: Ankylosing spondylitis (AS) impacts quality of life. We assessed patient-reported outcomes (PROs), pain, fatigue, health-related quality of life (HRQoL) and work productivity in a phase III trial of tofacitinib. METHODS: Adults with AS and with inadequate response/intolerance to ≥2 non-steroidal anti-inflammatory drugs received tofacitinib 5 mg twice daily or placebo for 16 weeks. Afterwards, all received open-label tofacitinib until week 48. Change from baseline to week 48 was determined for PROs: total back pain; nocturnal spinal pain; Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) overall spinal pain (Q2); Functional Assessment of Chronic Illness Therapy-Fatigue; BASDAI fatigue (Q1); AS Quality of Life (ASQoL); Short Form-36 Health Survey Version 2 (SF-36v2); EuroQoL-Five Dimension-Three Level health profile and Visual Analogue Scale; and the Work Productivity and Activity Impairment (WPAI) questionnaire. Improvements from baseline ≥minimum clinically important difference, and scores ≥normative values at week 16 were evaluated. RESULTS: In 269 randomised and treated patients, at week 16, there were greater least squares mean improvements from baseline with tofacitinib 5 mg twice daily versus placebo in BASDAI overall spinal pain (-2.85 vs -1.34), BASDAI fatigue (-2.36 vs -1.08), ASQoL (-4.03 vs -2.01) and WPAI overall work impairment (-21.49 vs -7.64) (all p<0.001); improvements continued/increased to week 48. Improved spinal pain with tofacitinib was seen by week 2. Patients receiving tofacitinib reported clinically meaningful PRO improvements at week 16. Percentages with PRO scores ≥normative values at week 16 were greater with tofacitinib in SF-36v2 Physical Component Summary, physical functioning and bodily pain domains (p≤0.05). CONCLUSIONS: In patients with AS, treatment with tofacitinib 5 mg twice daily resulted in clinically meaningful improvements in pain, fatigue, HRQoL and work productivity versus placebo to week 16, which were sustained to week 48. TRIAL REGISTRATION NUMBER: NCT03502616.

INTRODUCTION: This study characterized real-world demographic and baseline clinical characteristics, as well as treatment persistence and adherence, in patients with psoriatic arthritis (PsA) who had newly initiated tofacitinib treatment. METHODS: This retrospective cohort study included patients aged 18 years or older in the IBM MarketScan™ US database with at least one tofacitinib claim (first = index) between December 14, 2017 and April 30, 2019; PsA diagnoses on/within 12 months pre-index; and no diagnoses of rheumatoid arthritis any time pre-index. Patients were continuously enrolled for 12 months pre-index and 6 months post-index, with no pre-index claims for tofacitinib. Patient demographic and clinical characteristics on the day of index, and history of advanced treatments (including tofacitinib monotherapy or combination therapy), were recorded. Outcomes at 6 months post-index included tofacitinib persistence (less than 60-day gap without tofacitinib treatment) and adherence (proportion of days covered [PDC] and medication possession ratio 80% or higher). RESULTS: Of the 10,354 patients with tofacitinib claims within the study period, 318 patients with PsA met the inclusion criteria. More than 60% of patients received tofacitinib monotherapy post-index, with a mean duration of PsA of 760.5 days at index. For patients who received tofacitinib combination therapy post-index, methotrexate was the most common concomitant conventional synthetic disease-modifying antirheumatic drug. At 6 months post-index, persistence was similar in patients receiving tofacitinib monotherapy (69.8%) versus combination therapy (73.1%); adherence (as measured by PDC ≥ 0.8) was numerically lower in patients receiving tofacitinib monotherapy (56.8%) versus combination therapy (65.5%). CONCLUSIONS: This analysis of US-based claims data described patients who had newly initiated tofacitinib treatment an average of 2 years after PsA diagnosis, with approximately two-thirds of patients receiving tofacitinib monotherapy. Observed rates of tofacitinib persistence were similar across patients who received tofacitinib monotherapy and combination therapy 6 months after initiation; adherence rates were numerically lower in patients receiving monotherapy.
Tofacitinib is a drug approved to treat patients with psoriatic arthritis (PsA) that has been shown to improve PsA symptoms and quality of life in controlled clinical trials. However, there is not much information on everyday use of tofacitinib outside of clinical trials in the USA. This study is one of the first to describe the characteristics of patients with PsA in the USA who take tofacitinib, including their typical age, sex, where they live, how long they have had PsA, and how they use tofacitinib. Use of tofacitinib included how patients followed tofacitinib prescription timings and dose (adherence) and how long they took tofacitinib for after it was prescribed (persistence). We used data collected from a US health insurance claims database (IBM MarketScan™) for patients with PsA and at least one claim for tofacitinib. In total, 318 patients were included and over 60% of them received tofacitinib therapy only (monotherapy; no conventional synthetic disease-modifying antirheumatic drug [csDMARD] therapy). For patients treated with both tofacitinib and a csDMARD (combination therapy), methotrexate was the most common drug prescribed. Six months after their first prescription of tofacitinib, around 70% of patients were still taking tofacitinib (monotherapy or combination therapy). However, a slightly lower number of patients taking tofacitinib monotherapy were taking it as originally instructed (adherence 57%), compared with those taking tofacitinib combination therapy (adherence 66%). Our results provide valuable information on the use of tofacitinib in US real-life settings outside of clinical trials and could help to improve the quality of care for patients with PsA.

INTRODUCTION: To compare perceptions of disease control and treatment satisfaction between patients with psoriatic arthritis (PsA) in North America and Europe, and between participating countries within each region. METHODS: Data were collected from patients with self-reported PsA diagnoses using an online survey. Results from questions on perceptions of overall health, disease severity, PsA symptoms, PsA impacts, and treatment satisfaction/preferences were reported using descriptive statistics and Chi-square tests. RESULTS: A total of 456 patients from North America (Canada, n = 155; US, n = 301) and 417 patients from Europe (France, n = 123; Spain, n = 135; UK, n = 159) were included in this analysis. Patients in North America were more likely to rate their overall health as excellent/good compared with those in Europe (49 vs. 14%), but also rate their disease as severe (27 vs. 15%). Despite treatment, patients in North America and Europe still experienced musculoskeletal (92 vs. 91%) and skin/nail (62 vs. 58%) symptoms. Similar proportions of patients in North America vs. Europe experienced a social impact (81 vs. 85%); more patients in Europe vs. North America experienced PsA-related work impacts (83 vs. 74%). Satisfaction with PsA medication was more common in North America (89%) vs. Europe (79%), and more common in Spain (91%) vs. the UK (82%) or France (66%). Across all regions and countries, ≥ 75% of patients agreed that symptoms were controlled. However, ≥ 66% wished they had more medication choices, and ≥ 84% wanted to change something about their medication. CONCLUSIONS: Although perception of overall health and disease severity varied, many patients from both regions still experienced symptoms despite receiving medications for PsA, wished they had greater choice of medications, and/or would like to change an aspect of their medications. While these survey findings are subject to selection bias, they do indicate there is scope to improve the treatment of PsA.
Psoriatic arthritis (PsA) is a disease that can cause joint pain and stiffness, and is often associated with a skin rash called psoriasis. These symptoms can affect quality of life, and patients and doctors should work together when choosing treatment. There has not been a lot of information on what patients think about their disease and their medicines. We found that patients from different regions and countries had different opinions, and that treatment of PsA can be improved. For example, patients in North America were more likely to say that their overall health was excellent or good, compared with patients in Europe. However, more patients in North America than in Europe described their PsA disease as severe. Similar numbers of patients in both regions experienced impacts on their social life due to their PsA, but patients in Europe were more likely to report that PsA affected their work life compared with patients in North America. More patients in North America than in Europe were satisfied with their medicines, but patients across all regions and countries still had symptoms even when they took medicines. Many patients also wished they had more options and wanted to change something about their medicines. These findings were based on an online survey. Patients from North America (Canada and the US) and Europe (France, Spain, and the UK) answered questions about their PsA disease and medicines. We only compared answers between patients from North America and Europe, and between countries within each region.
RESUMEN
BACKGROUND: This study examined the time to clinically meaningful response in patients with active psoriatic arthritis treated with tofacitinib, adalimumab, or placebo switching to tofacitinib. METHODS: Data were from two phase 3 studies, OPAL Broaden (12 months) and OPAL Beyond (6 months). Patients received tofacitinib 5 or 10 mg twice daily (BID), adalimumab 40 mg once every 2 weeks (OPAL Broaden only), or placebo switching to tofacitinib 5 or 10 mg BID at month 3. Baseline to initial response time was according to pre-defined clinically meaningful criteria on Health Assessment Questionnaire-Disability Index (HAQ-DI; ≥ 0.35-point improvement), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F; ≥ 4-point improvement), Psoriatic Arthritis Disease Activity Score (PASDAS; post-baseline score ≤ 3.2 and > 1.6-point improvement from baseline), and minimal disease activity (MDA; meeting at least 5 of 7 criteria) composite. RESULTS: In OPAL Broaden, median time to initial HAQ-DI score response was 29, 53, and 30 days in patients treated with tofacitinib 5 mg BID, tofacitinib 10 mg BID, or adalimumab, compared with 162 and 112 days in patients treated with placebo switching to tofacitinib 5 or 10 mg BID at month 3, respectively. Across studies, median time to initial FACIT-F total score response was shorter in patients receiving tofacitinib 5 mg BID (31 days) vs other groups (84-92 days). Median time to initial response was approximately 11 (MDA)/6-9 months (PASDAS) in tofacitinib/adalimumab groups in OPAL Broaden. CONCLUSION: This analysis demonstrates tofacitinib's efficacy on most patient-reported and clinical endpoints over time and shows a shorter time to initial, clinically meaningful response in patients receiving tofacitinib vs patients switching from placebo to tofacitinib.

OBJECTIVE: Post 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. METHODS: Patients 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). RESULTS: From 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. CONCLUSION: Patients 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.

OBJECTIVE: Tofacitinib is an oral JAK inhibitor for the treatment of rheumatoid arthritis (RA). To better understand tofacitinib treatment responses, we used group-based trajectory modeling to investigate distinct disease activity trajectories and associated baseline variables in patients with active RA. METHODS: This post hoc analysis used data from a phase III study of methotrexate-naive patients receiving tofacitinib 5 mg twice daily. Changes in the 4-variable Disease Activity Score in 28 joints, using the erythrocyte sedimentation rate (DAS28-ESR) from baseline to month 24 were used in group-based trajectory modeling to identify distinct disease activity trajectories. Patient and disease characteristics, changes in radiographic progression and patient-reported outcomes, and safety up to month 24 were compared among trajectory groups. RESULTS: From 346 methotrexate-naive patients, 5 disease trajectory groups, defined by DAS28-ESR scores, were identified, which progressed from high disease activity (HDA) to remission (group 1, n = 28), to low disease activity (LDA) rapidly (group 2, n = 107), to moderate disease activity (group 3, n = 98), to LDA gradually (group 4, n = 46), or remained in HDA (group 5, n = 67), at month 24. At baseline, groups 1 and 2 generally had lower disease activity and more favorable patient-reported outcomes, compared with other groups. Improvements in radiographic progression and patient-reported outcomes over 24 months were generally consistent with DAS28-ESR-predicted disease activity trajectories. Adverse event rates were generally comparable across groups. CONCLUSION: Distinct phenotypic subgroups identified heterogeneity in patients with RA normally analyzed as a single population. Trajectory modeling may enable separation of clinically meaningful subsets of patients with RA, and may help optimize treatment outcomes.

BACKGROUND: Pain is a core domain of psoriatic arthritis (PsA). This post hoc analysis evaluated time to pain improvement and the impact of baseline pain severity on pain response in patients with PsA receiving tofacitinib. METHODS: Data from two trials (NCT01877668; NCT01882439) in patients receiving tofacitinib 5 mg twice daily, placebo switching to tofacitinib 5 mg twice daily at month 3 (placebo-to-tofacitinib) or adalimumab (NCT01877668 only) were included. Improvement in pain (≥30%/≥50% decrease from baseline in Visual Analogue Scale pain score) was assessed; median time to initial (first post-baseline visit)/continued (first two consecutive post-baseline visits) pain improvement was estimated (Kaplan-Meier) for all treatment arms. A parametric model was used to determine the relationship between baseline pain severity and time to pain response in patients receiving tofacitinib. RESULTS: At month 3, more patients experienced pain improvements with tofacitinib/adalimumab versus placebo. Median days (95% CI) to initial/continued pain improvements of ≥30% and ≥50%, respectively, were 55 (29-57)/60 (57-85) and 85 (57-92)/171 (90-not estimable (NE)) for tofacitinib, versus 106 (64-115)/126 (113-173) and 169 (120-189)/NE (247-NE) for placebo-to-tofacitinib. Pain improvements were also experienced more quickly for adalimumab versus placebo. Predicted time to ≥30%/≥50% pain improvement was shorter in patients with higher baseline pain versus lower baseline pain (tofacitinib arm only). CONCLUSIONS: In patients with PsA, pain improvements were experienced by more patients, and more rapidly, with tofacitinib and adalimumab versus placebo. In those receiving tofacitinib, higher baseline pain was associated with faster pain improvements.

OBJECTIVE: To assess the efficacy/safety of tofacitinib in adult patients with active ankylosing spondylitis (AS). METHODS: This phase III, randomised, double-blind, placebo-controlled study enrolled patients aged ≥18 years diagnosed with active AS, meeting the modified New York criteria, with centrally read radiographs, and an inadequate response or intolerance to ≥2 non-steroidal anti-inflammatory drugs. Patients were randomised 1:1 to receive tofacitinib 5 mg two times per day or placebo for 16 weeks. After week 16, all patients received open-label tofacitinib until week 48. The primary and key secondary endpoints were Assessment of SpondyloArthritis international Society ≥20% improvement (ASAS20) and ≥40% improvement (ASAS40) responses, respectively, at week 16. Safety was assessed throughout. RESULTS: 269 patients were randomised and treated: tofacitinib, n=133; placebo, n=136. At week 16, the ASAS20 response rate was significantly (p<0.0001) greater with tofacitinib (56.4%, 75 of 133) versus placebo (29.4%, 40 of 136), and the ASAS40 response rate was significantly (p<0.0001) greater with tofacitinib (40.6%, 54 of 133) versus placebo (12.5%, 17 of 136). Up to week 16, with tofacitinib and placebo, respectively, 73 of 133 (54.9%) and 70 of 136 (51.5%) patients had adverse events; 2 of 133 (1.5%) and 1 of 136 (0.7%) had serious adverse events. Up to week 48, with tofacitinib, 3 of 133 (2.3%) patients had adjudicated hepatic events, 3 of 133 (2.3%) had non-serious herpes zoster, and 1 of 133 (0.8%) had a serious infection; with placeboâtofacitinib, 2 (1.5%) patients had non-serious herpes zoster. There were no deaths, malignancies, major adverse cardiovascular events, thromboembolic events or opportunistic infections. CONCLUSIONS: In adults with active AS, tofacitinib demonstrated significantly greater efficacy versus placebo. No new potential safety risks were identified. TRIAL REGISTRATION NUMBER: NCT03502616.

BACKGROUND: In psoriatic arthritis (PsA), further understanding of the relationships between clinical measures and patient-reported outcomes (PROs) is needed. This post hoc analysis evaluated associations between minimal disease activity (MDA) as a continuous outcome (termed ScoreMDA) or Psoriatic Arthritis Disease Activity Score (PASDAS) with selected PROs not included in the composite measures. METHODS: Data from two phase 3 studies of tofacitinib in PsA (OPAL Broaden [NCT01877668; N = 422]; OPAL Beyond [NCT01882439; N = 394]) were included. MDA (binary outcome) was defined as meeting ≥5/7 criteria. For ScoreMDA, each criterion was assigned a value (1 = true; 0 = false; score range, 0-7; scores ≥5 indicated MDA). For PASDAS (score range, 0-10), higher scores indicated worse disease activity. PROs analyzed included Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Patient's Assessment of Arthritis Pain visual analog scale (Pain VAS), and EuroQoL-Five Dimensions-Three Level Health Questionnaire visual analog scale (EQ-5D-3L VAS) and utility index. Relationships were evaluated using repeated measures regression models. RESULTS: Similar, approximately linear relationships were confirmed between PASDAS or ScoreMDA and PROs in both studies. In OPAL Broaden and OPAL Beyond, a one-point difference in PASDAS was associated with clinically relevant differences in PROs, including EQ-5D-3L VAS (- 6.7 mm, - 6.9 mm), Pain VAS (9.9 mm, 10.7 mm), and FACIT-F (- 2.8, - 3.3). A one-point difference in ScoreMDA was associated with clinically relevant differences in PROs, including EQ-5D-3L VAS (5.0 mm, 5.5 mm) and FACIT-F (1.9, 2.7) in OPAL Broaden and OPAL Beyond, respectively. CONCLUSIONS: Linear associations between PASDAS or ScoreMDA and PROs provide interpretable and quantifiable metrics between composite clinical measures and PROs, highlighting the importance of these measures in understanding the relevance of treat-to-target goals in PsA.

BACKGROUND: Tofacitinib is an oral Janus kinase inhibitor for the treatment of psoriatic arthritis, rheumatoid arthritis, and ulcerative colitis. This study evaluated the efficacy and safety of tofacitinib 5 mg twice daily monotherapy after methotrexate withdrawal. METHODS: OPAL Balance was an open-label, long-term extension study of tofacitinib in patients with psoriatic arthritis who participated in the OPAL Broaden and OPAL Beyond phase 3 studies. This 12-month, randomised, double-blind, placebo-controlled, methotrexate withdrawal substudy (50 centres, 14 countries) included patients from OPAL Balance who completed tofacitinib treatment for 24 months or more (≥3 months' stable tofacitinib 5 mg twice daily) and were receiving methotrexate (7·5-20 mg/week). Patients were blindly randomised (1:1) using interactive response technology and received open-label tofacitinib 5 mg twice daily with either placebo (tofacitinib 5 mg twice daily plus placebo group) or continued methotrexate (tofacitinib 5 mg twice daily plus methotrexate group). Patients were masked to placebo or methotrexate, with identical capsules used. Coprimary endpoints were changes from substudy baseline in psoriatic arthritis disease activity score (PASDAS) and health assessment questionnaire-disability index (HAQ-DI) at month 6 in all randomised patients with one or more substudy drug dose. Safety was assessed throughout. No specific statistical hypothesis (either superiority or non-inferiority) was tested. The study (OPAL Balance) is registered with ClinicalTrials.gov (NCT01976364) and is complete. FINDINGS: Between Oct 30, 2017, and May 20, 2019, 180 patients from OPAL Balance who were eligible for the substudy were randomly assigned to treatment (90 patients received tofacitinib 5 mg twice daily plus placebo and 89 patients assigned to tofacitinib plus methotrexate; one patient was not treated because of randomisation error). At month 6, least squares mean (LSM) changes in PASDAS were 0·23 (SE 0·08) for tofacitinib 5 mg twice daily plus placebo and 0·14 (0·08) for tofacitinib 5 mg twice daily plus methotrexate (treatment difference LSM 0·09 [95% CI -0·13 to 0·31]), and changes in HAQ-DI were 0·04 (0·03) and 0·02 (0·03), respectively (treatment difference 0·03 [-0·05 to 0·10]). Rates of adverse events, discontinuations because of adverse events, adverse events of special interest, and laboratory changes were generally similar between treatment groups, although liver enzyme elevations were more common with tofacitinib 5 mg twice daily plus methotrexate than tofacitinib 5 mg twice daily plus placebo. Flares of worsening symptoms was reported in one (1%) of 90 patients in the tofacitinib 5 mg twice daily plus placebo group (recorded as psoriatic arthropathy). INTERPRETATION: Some patients with psoriatic arthritis who are stable on tofacitinib 5 mg twice daily with background methotrexate might be able to discontinue methotrexate without clinically meaningful changes in disease activity and safety.

RESUMEN
BACKGROUND: Tofacitinib is an oral Janus kinase inhibitor for the treatment of psoriatic arthritis. Here we report the final analysis of Oral Psoriatic Arthritis Trial (OPAL) Balance, a 36-month long-term extension study, with a 12-month methotrexate withdrawal substudy, that assessed tofacitinib safety, tolerability, and efficacy in patients with active psoriatic arthritis. METHODS: For this open-label, long-term extension study, which was run at 124 centres in 16 countries, eligible patients had participated in the OPAL Broaden or OPAL Beyond phase 3 studies. Patients could enter OPAL Balance up to 3 months after completing one of the qualifying studies or discontinuing for reasons other than an adverse event related to study drug. In OPAL Balance, patients received open-label tofacitinib 5 mg twice daily, with increases to 10 mg twice daily for inadequate symptom control allowed from month 1, and reductions to 5 mg twice daily allowed thereafter for safety. Specific conventional synthetic disease-modifying antirheumatic drugs could be continued concomitantly. The primary endpoints were incidence and severity of adverse events, the incidence of laboratory abnormalities, and changes from baseline in laboratory parameters. Participants who were eligible could enter the randomised, double-blind, methotrexate withdrawal substudy (open-label tofacitinib 5 mg twice daily plus either masked placebo or masked methotrexate); safety data from which are included here (up to month 48). Efficacy was reported up to month 36 (substudy data excluded). The risk period for safety outcomes was the time from treatment exposure to the last dose plus 28 days or date of last observation. OPAL Balance is registered with ClinicalTrials.gov (NCT01976364) and is now complete. FINDINGS: Between Feb 17, 2014, and March 28, 2016, 686 patients were enrolled and given tofacitinib 5 mg or 10 mg twice daily (179 patients were treated in the substudy and 453 [66%] of 686 completed the long-term extension study or substudy; mean treatment duration 794·6 days [SD 329·2] in long-term extension study, 879·0 days [396·6] in long-term extension study plus substudy). The mean age of participants in the all tofacitinib group was 48·8 years (SD 11·8) and 370 (54%) of 686 participants were female. Up to month 48, 574 (84%) of 686 participants reported all-cause adverse events, 115 (17%) reported serious adverse events, and 78 (11%) discontinued due to an adverse event. Six patients died, one within the risk period (incidence of 0·1 patients with events [95% CI 0·0-0·3] per 100 person-years). The incidences of adverse events of special interest, reported as number of patients with events per 100 person-years, included: 1·7 (1·2-2·5) for herpes zoster (non-serious and serious); 1·0 (0·6-1·6) for serious infections; 0·4 (0·1-0·8) for opportunistic infections; 0·7 (0·4-1·2) for malignancies (excluding non-melanoma skin cancer [NMSC]); 0·9 (0·5-1·5) for NMSC; 0·2 (0·1-0·6) for major adverse cardiovascular events; 0·1 (0·0-0·3) for pulmonary embolism; and 0·4 (0·1-0·8) for arterial thromboembolism. No deep vein thromboses occurred. Laboratory parameter changes were as expected with treatment. Efficacy was sustained up to month 36. INTERPRETATION: This analysis supports the long-term safety (up to 48 months) and efficacy (up to 36 months) of tofacitinib in patients with psoriatic arthritis, which were consistent with previous phase 3 studies.
