Mental health status potentially influences treatment responses. The effect of probable anxiety and/or depressive disorder (pADD) on tofacitinib efficacy, patient-reported outcomes (PROs), and safety in psoriatic arthritis (PsA) was assessed. This was a post hoc analysis of two phase 3 trials in patients with PsA receiving tofacitinib, adalimumab, or placebo, and an open-label extension study. Outcomes were stratified by presence/absence of baseline pADD (Short Form-36 Health Survey [SF-36] Mental Component Summary score ≤ 38/ > 38). American College of Rheumatology ≥ 20

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. 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

ORAL Surveillance, a post-authorisation safety study of patients with rheumatoid arthritis (RA) enriched for cardiovascular (CV) risk, demonstrated increased risk of major adverse CV events (MACE) and malignancies (excluding non-melanoma skin cancer [NMSC]) for tofacitinib versus tumour necrosis factor inhibitors (TNFi). This analysis of a real-world Canadian observational study evaluated tofacitinib safety/effectiveness in patients meeting or not meeting CV risk criteria. CANTORAL included patients with moderate-to-severe RA initiating tofacitinib (10/2017–07/2020; N = 504). Interim data (data-cut: 07/2021) were stratified as CV risk-enriched (CV+ ; patients ≥ 50 years with ≥ 1 additional CV risk factor) or not CV risk-enriched (CV−; ≥ 50 years without additional CV risk factors and 18–49 years with/without CV risk factors). Safety and persistence were evaluated to month (M) 36. Effectiveness outcomes to M18 included Clinical Disease Activity Index (CDAI)-defined low disease activity (LDA)/remission (CANTORAL co-primary endpoints) and Disease Activity Score in 28 joints, C-reactive protein (DAS28-4[CRP]) < 3.2/ < 2.6. Overall, 272/232 patients were included in CV+ /CV− cohorts (full analysis set) (435/356 patient-years [safety analysis set]). Incidence rates (events/100 patient-years) in CV+ /CV− cohorts were 138.5/112.5 for treatment-emergent adverse events (AEs); 17.0/5.6 for serious AEs; 1.2/0.3 for deaths; 5.5/1.7 for serious infections; 1.4/1.1 for herpes zoster; 1.6/0.0 for MACE; 2.1/0.3 for malignancies (excluding NMSC); 0.7/0.6 for NMSC; 0.5/0.0 for venous thromboembolic events. Persistence was generally comparable between cohorts. In CV+ /CV− cohorts, at M6, CDAI LDA and remission rates were 51.5

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.

Racial disparities in disease activity, clinical outcomes, and treatment survival persist despite advancements in rheumatoid arthritis (RA) therapies and clinical management. In this post hoc analysis of pooled data from the tofacitinib global clinical program, we evaluated the impact of race on the efficacy and safety of tofacitinib in patients with RA. Data were pooled from 15 phase 2–3b/4 studies of patients with RA treated with tofacitinib 5 or 10 mg twice daily, adalimumab, or placebo. Outcomes were stratified by self-reported patient race (White/Black/Asian/Other). Efficacy outcomes to month 12 included: American College of Rheumatology (ACR)20/50/70 responses, Clinical Disease Activity Index (CDAI)/Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] low disease activity (LDA) rates, least squares (LS) mean change from baseline (∆) in CDAI, DAS28-4 (ESR), Health Assessment Questionnaire-Disability Index (HAQ-DI), and Pain [Visual Analog Scale (VAS)].

Background Evaluate the impact of sex on tofacitinib efficacy, safety and persistence (time to discontinuation) in patients with psoriatic arthritis (PsA). Methods Data were pooled from two phase 3 randomised controlled trials. Patients were randomised to tofacitinib 5 mg or 10 mg two times per day, adalimumab 40 mg every 2 weeks or placebo. Efficacy outcomes to month 12 included American College of Rheumatology (ACR)20/50/70, minimal disease activity (MDA), Psoriasis Area Severity Index (PASI)75, change from baseline (∆) in Health Assessment Questionnaire-Disability Index (HAQ-DI) and ∆Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Safety was assessed to month 12 and persistence was assessed to month 42 of a long-term extension study. Results Overall, 816 patients were included (54.3% females). At baseline, higher tender joint counts, enthesitis scores and worse HAQ-DI and FACIT-F were reported in females versus males; presence of dactylitis and PASI were greater in males versus females. At month 3, tofacitinib efficacy generally exceeded placebo in both sexes. Overall, similar ACR20/50/70, PASI75, ∆HAQ-DI and ∆FACIT-F were observed for tofacitinib between sexes; females were less likely to achieve MDA. Similar proportions of males/females receiving tofacitinib (both doses) experienced treatment-emergent adverse events (AEs). Serious AEs occurred in 3.4%/6.6% and 4.0%/5.9% males/females with tofacitinib 5 mg and 10 mg two times per day. Persistence was generally similar between sexes. Conclusion Tofacitinib efficacy exceeded placebo in both sexes and was comparable between sexes. Consistent with previous studies of PsA treatments, females were less likely to achieve MDA, likely due to baseline differences. Safety and time to discontinuation were generally similar between sexes. Trial registration number NCT01877668 ; NCT01882439 ; NCT01976364 .

ObjectivesEfficacy and safety of tofacitinib, an oral Janus kinase inhibitor, were evaluated in a 6-month, double-blind, phase 3 study in Chinese patients with active (polyarthritic) psoriatic arthritis (PsA) and inadequate response to ≥1 conventional synthetic disease-modifying antirheumatic drug.MethodsPatients were randomised (2:1) to tofacitinib 5 mg twice daily (N=136) or placebo (N=68); switched to tofacitinib 5 mg twice daily after month (M)3 (blinded). Primary endpoint: American College of Rheumatology (ACR50) response at M3. Secondary endpoints (through M6) included: ACR20/50/70 response; change from baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI); ≥75% improvement in Psoriasis Area and Severity Index (PASI75) response, and enthesitis and dactylitis resolution. Safety was assessed throughout.ResultsThe primary endpoint was met (tofacitinib 5 mg twice daily, 38.2%; placebo, 5.9%; p<0.0001). M3 ACR20/ACR70/PASI75 responses, and enthesitis and dactylitis resolution rates, were higher and HAQ-DI reduction was greater for tofacitinib 5 mg twice daily versus placebo. Incidence of adverse events (AEs)/serious AEs (M0–3): 68.4%/0%, tofacitinib 5 mg twice daily; 75.0%/4.4%, placebo. One death was reported with placebo→tofacitinib 5 mg twice daily (due to accident). One serious infection, non-serious herpes zoster, and lung cancer case each were reported with tofacitinib 5 mg twice daily; four serious infections and one non-serious herpes zoster case were reported with placebo→tofacitinib 5 mg twice daily (M0–6). No non-melanoma skin cancer, major adverse cardiovascular or thromboembolism events were reported.ConclusionIn Chinese patients with PsA, tofacitinib efficacy was greater than placebo (primary and secondary endpoints). Tofacitinib was well tolerated; safety outcomes were consistent with the established safety profile in PsA and other indications.Trial registration numberNCT03486457.

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). 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). 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

ObjectiveThe Canadian Tofacitinib for Rheumatoid Arthritis Observational (CANTORAL) is the first Canadian prospective, observational study assessing tofacitinib. The objective was to assess effectiveness and safety for moderate to severe rheumatoid arthritis (RA). Coprimary and secondary outcomes are reported from an interim analysis.MethodsPatients initiating tofacitinib from October 2017 to July 2020 were enrolled from 45 Canadian sites. Coprimary outcomes (month 6) included the Clinical Disease Activity Index (CDAI)–defined low disease activity (LDA) and remission. Secondary outcomes (to month 18) included the CDAI and the 4‐variable Disease Activity Score in 28 joints (DAS28) using the erythrocyte sedimentation rate (ESR)/C‐reactive protein (CRP) level to define LDA and remission; the proportions of patients achieving mild pain (visual analog scale <20 mm), and moderate (≥30%) and substantial (≥50%) pain improvements; and the proportions of patients achieving a Health Assessment Questionnaire disability index (HAQ DI) score greater or equal to normative values (≤0.25) and a HAQ DI score greater or equal to minimum clinically important difference (MCID) (≥0.22). Safety was assessed to month 36.ResultsOf 504 patients initiating tofacitinib, 44.4% received concomitant methotrexate. At month 6, 52.9% and 15.4% of patients were in CDAI‐defined LDA and remission, respectively; a similar proportion of patients achieved outcomes by month 3 (first post‐baseline assessment). By month 3, 27.2% and 41.7% of patients, respectively, were in DAS28‐ESR–defined LDA and DAS28‐CRP <3.2; 14.7% and 25.8% achieved DAS28‐ESR remission and DAS28‐CRP <2.6. By month 3, mild pain and moderate and substantial pain improvements occurred in 29.6%, 55.6%, and 42.9% of patients, respectively; 19.9% and 53.7% of patients achieved a HAQ DI score greater than or equal to normative values and a HAQ DI score greater than or equal to MCID, respectively. Outcomes were generally maintained to month 18. Incidence rates (events per 100 patient‐years) for treatment‐emergent adverse events (AEs), serious AEs, and discontinuations due to AEs were 126.8, 11.9, and 14.5, respectively, and AEs of special interest were infrequent.ConclusionTofacitinib was associated with early and sustained improvement in RA signs and symptoms in real‐world patients. Effectiveness and safety were consistent with the established tofacitinib clinical profile.

Objective.To evaluate the effect of tofacitinib (TOF) on American College of Rheumatology (ACR) response criteria components in patients with rheumatoid arthritis (RA).Methods.This post hoc analysis pooled data from RA phase III randomized controlled trials (RCTs) assessing TOF 5 or 10 mg BID, adalimumab (ADA), or placebo, with conventional synthetic disease-modifying antirheumatic drugs, and a phase IIIb/IV RCT assessing TOF 5 mg BID monotherapy, TOF 5 mg BID with methotrexate (MTX), or ADA with MTX. Outcomes included proportions of patients achieving ACR20/50/70 responses and ≥ 20/50/70% improvement rates in ACR components at week 2 and months 1, 3, and 6; and mean percent improvement in ACR components and Clinical or Simplified Disease Activity Index (CDAI or SDAI) low disease activity or remission rates, at month 3, for ACR20/50/70 responders.Results.Across treatment groups, ≥ 20/50/70% improvement rates were numerically higher for most physician- vs patient-reported measures. In phase III RCTs, at earlier timepoints, ≥ 50/70% improvements in patient global assessment of disease activity, pain, and physician global assessment were similar. Among ACR20 responders receiving TOF, mean percent improvements for tender and swollen joint counts were > 70% at month 3. CDAI/SDAI remission was achieved at month 3 by 27.8–45.0% of ACR70 responders receiving TOF.Conclusion.Among ACR20 responders treated with TOF, physician-reported components particularly exceeded 20% response improvement. At month 3, disease state generally did not corroborate ACR70 response criteria. Divergences between physician- and patient-reported measures highlight the importance of identifying appropriate patient-reported outcome targets to manage RA symptoms in clinical practice.
