Abstract Objectives Describe tofacitinib safety from an integrated analysis of randomized controlled trials (RCTs) in patients with ankylosing spondylitis (AS). Method Pooled data from Phase 2 (NCT01786668; 04/2013–03/2015)/Phase 3 (NCT03502616; 06/2018–08/2020) RCTs in AS patients were analyzed (3 overlapping cohorts): 16-week placebo-controlled (tofacitinib 5 mg twice daily [BID] [n = 185]; placebo [n = 187]); 48-week only-tofacitinib 5 mg BID (n = 316); 48-week all-tofacitinib (≥ 1 dose of tofacitinib 2, 5, or 10 mg BID; n = 420). Baseline 10-year atherosclerotic cardiovascular disease (ASCVD) risk was determined in patients without history of ASCVD (48-week cohorts). Adverse events (AEs)/AEs of special interest were evaluated/compared with findings from other tofacitinib programs (16 Phase 2/Phase 3 rheumatoid arthritis [RA]; 2 Phase 3 psoriatic arthritis [PsA] RCTs) and a real-world cohort of AS patients initiating biologic disease-modifying antirheumatic drugs (US MarketScan). Results Most patients (> 75%; 48-week cohorts) without history of ASCVD had low baseline 10-year ASCVD risk. One patient (tofacitinib 5 mg BID; in all 3 cohorts) had a serious infection (aseptic meningitis). Herpes zoster (non-serious) occurred in the 48-week only-tofacitinib 5 mg BID (n = 5 [1.6%]) and all-tofacitinib (n = 7 [1.7%]; one multi-dermatomal [tofacitinib 10 mg BID]) cohorts. No deaths, opportunistic infections, tuberculosis, malignancies, major adverse cardiovascular events, thromboembolic events, gastrointestinal perforations occurred. Limitations: short RCT durations/low patient numbers within cohorts. Conclusion Tofacitinib 5 mg BID was well tolerated to 48 weeks in AS patients; safety profile was consistent with RA/PsA clinical programs and a cohort of AS patients from US routine clinical practice. Clinical trial registration numbers NCT01786668 (2013-02-06); NCT03502616 (2018-04-11).

Abstract Introduction Routine care studies of psoriatic arthritis (PsA) and ankylosing spondylitis (AS) demonstrated attenuated responses to tumor necrosis factor inhibitors in current/past versus never smokers. This post hoc analysis assessed tofacitinib efficacy and safety in patients with PsA or AS by cigarette smoking status at trial screening. Methods Pooled data from phase 3 and long-term extension (safety only) PsA trials and phase 2 and 3 AS trials were assessed by current/past versus never smoker status. Analysis included efficacy and safety data for tofacitinib 5 (PsA/AS) and 10 (PsA only) mg twice daily (BID) or placebo, and safety data in AS for tofacitinib 2 and 10 mg BID. Efficacy outcomes included American College of Rheumatology ≥ 50% responses (ACR50) and minimal disease activity (MDA) responses to month (M)6/M3 (tofacitinib/placebo) in PsA; and ≥ 40% improvement in Assessment of SpondyloArthritis international Society responses (ASAS40) and AS Disease Activity Score (ASDAS)

Abstract 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

Abstract 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.

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.

Abstract 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.

Abstract 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

Abstract 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.

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 (ClinicalTrials.gov): 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.

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)

Abstract 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.

Abstract Introduction Tofacitinib is an oral Janus kinase inhibitor for the treatment of psoriatic arthritis (PsA). We report the interim safety, tolerability, and efficacy of tofacitinib in PsA patients in OPAL Balance, a 3-year, open-label, long-term extension study (data cut-off: August 2017; database not locked, data may change). Methods Eligible patients from two phase (P) 3 (P3) tofacitinib PsA studies (OPAL Broaden, NCT01877668; OPAL Beyond, NCT01882439) entered OPAL Balance ≤ 3 months after completing the P3 study or discontinuing for reasons other than study-drug-related adverse events (AEs). Patients received open-label tofacitinib 5 mg twice daily (BID), with adjustments to 10 mg BID permitted post-month (M) 1. Certain concomitant conventional synthetic disease-modifying antirheumatic drugs were allowed. Primary endpoints were incidence/severity of AEs and laboratory abnormalities, and changes from baseline in laboratory parameters (reported up to M36 and M30, respectively). Efficacy (clinical/patient-reported outcomes) was reported through M30. Results A total of 686 patients were treated; at data cut-off, 68.2% remained in the study. Mean (range) treatment duration was 641 (1–1032) days; total treatment duration was 1153.2 patient-years. By M36, 79.6, 13.8, and 8.6% of patients reported AEs, serious AEs, and discontinuations due to AEs, respectively. Five deaths occurred; one within the risk period (incidence rate [IR; patients with events/100 patient-years] 0.1). IRs for AEs of special interest were: all (non-serious and serious) herpes zoster, 1.7; serious infections, 0.9; opportunistic infections, 0.3 (all disseminated/multi-dermatomal herpes zoster); malignancies excluding non-melanoma skin cancer (NMSC), 0.8; NMSC, 1.0; major adverse cardiovascular events, 0.3; pulmonary embolisms, 0.1; and arterial thromboembolisms, 0.4. No patients had deep vein thrombosis. Alanine aminotransferase and aspartate aminotransferase levels were elevated ≥ 3-fold the upper limit of normal in 4.0 and 2.2% of patients, respectively. Changes in laboratory parameters were generally stable over time, although lymphocyte counts decreased slightly. Efficacy was maintained through M30. Conclusions In this interim analysis of OPAL Balance, tofacitinib safety and efficacy in patients with PsA appeared to be consistent with those of the P3 studies. Efficacy was maintained over time. Trial Registration ClinicalTrials.gov identifier: NCT01976364.

ABSTRACT Objective Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This post hoc analysis evaluated tofacitinib persistence in patients with RA in long‐term extension (LTE) studies up to 9.5 years. Methods Data were pooled from two LTE studies: ORAL Sequel (NCT00413699) and Study A3921041 (NCT00661661). Patients received tofacitinib 5 or 10 mg twice daily (BID), as monotherapy or with background conventional synthetic disease‐modifying antirheumatic drugs. Kaplan‐Meier estimates for tofacitinib drug survival and reasons for discontinuation were evaluated. Baseline factors were analyzed as predictors of persistence. Results In 4967 tofacitinib‐treated patients entering LTE studies, mean (maximum) treatment duration was 3.5 (9.4) years. Median drug survival (95% confidence interval) was 4.9 (4.7, 5.1) years. Estimated 2‐ and 5‐year drug survival rates were 75.5% and 49.4%, respectively. Median drug survival was similar between the tofacitinib 5 and 10 mg BID groups, and slightly higher for patients receiving tofacitinib monotherapy versus combination therapy. Overall, 50.7% of patients discontinued tofacitinib; of these, 47.2% were due to adverse events and 7.1% for lack/loss of efficacy. An increased risk of discontinuation was associated with baseline diabetes, hypertension, negative anticyclic citrullinated peptide (anti‐CCP), negative rheumatoid factor (RF), and inadequate response to tumor necrosis factor inhibitors (TNFi‐IR). Conclusion Median drug survival of tofacitinib‐treated patients participating in LTE studies was approximately 5 years and was similar for tofacitinib dosed at 5 and 10 mg BID. Reduced drug survival was associated with negative anti‐CCP/RF status, TNFi‐IR, and certain comorbidities. These data support tofacitinib use for long‐term management of RA.

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.
