Real world evidence on the effectiveness and safety of tofacitinib in ulcerative colitis in Lebanon

ObjectiveTo evaluate the effectiveness and safety of tofacitinib in patients with ulcerative colitis (UC) in clinical practice in Lebanon.DesignThis was a retrospective cross-sectional study. The data were collected from hospital records. Patients with moderate to severe UC treated with tofacitinib between 2018 and 2021 were included. Patients’ demographics, disease-specific characteristics, clinical assessment at three time points (8, 26, and 52 weeks), endoscopic evaluation at 24 weeks, and adverse events were collected.ResultsA total of 60 UC patients with a mean duration of disease of 7.9 ± 4.7 years were enrolled. 61.7% of patients had extensive disease, and 58.3% had received ≥ 1 biologic prior to tofacitinib. Clinical remission was reported in 25, 34, and 31 patients (41.7%, 56.7%, and 56.4%) at 8, 26, and 52 weeks respectively. Endoscopic remission (endoscopic Mayo score 0 or 1) was observed in 58.3% of patients at 52 weeks. About one-third of patients (31.7%) stopped tofacitinib at one year, primarily for lack of efficacy or loss of response, with no significant difference between biologics-naïve and experienced patients (24% vs. 37.1% respectively). No serious adverse events or deaths were reported. Adverse events were reported in 3 patients (5.0%) - one C. difficile infection, one case of reversible lymphopenia, and one case of facial acne. No serious adverse events or deaths were noted. On multivariate analysis, biologic-naïve status and reduction or normalization of CRP were associated with clinical remission (OR = 10.87, 95% CI = 1.57, 100, and OR = 78.47, 95% CI = 2.09, 2940.32 respectively), while reduction or normalization of CRP was associated with endoscopic remission at 1 year (OR = 19.03, 95% CI = 1.64, 221.09).ConclusionTofacitinib was effective in the treatment of moderately severe ulcerative colitis in this real-world cohort in Lebanon. Further, the predictors associated with clinical and endoscopic remissions were found to be biologic-naïve status and reduction in CRP. Observed AEs were consistent with the known safety profile. One of the major limitations of this study is the smaller sample size and the retrospective nature of the study.

Efficacy and Safety of Tofacitinib in Patients with Psoriatic Arthritis or Ankylosing Spondylitis by Cigarette Smoking Status.

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 phase2 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 twicedaily (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) < 2.1 responses to week (W)16 in AS. Safety was assessed to M48/W48 (PsA/AS), adjusted for treatment/smoking status/median body mass index (BMI) status/sex/trial/treatment-smoking status interaction. PsA/AS cohorts included 342/178 current/past and 572/194 never smokers. Tofacitinib efficacy was generally greater versus placebo to M3/W6 (PsA/AS), and comparable in current/past and never smokers to M6/W16 (PsA/AS). In patients receiving ≥ 1tofacitinib dose, adjusted treatment-emergent adverse event (TEAE)/serious AE (SAE)/discontinuation due to AE incidence rates (IRs) to M48 in PsA were higher in current/past versus never smokers; adjusted IRs to W48 in AS were higher in current/past versus never smokers for TEAEs, but similar for SAEs/discontinuation due to AEs. In both patients with PsA and AS, tofacitinib efficacy was greater versus placebo, and comparable across smoking categories. Adjusted IRs were higher in current/past versus never smokers for TEAEs, SAEs, discontinuation due to AEs in PsA, and for TEAEs in AS, complementing reports of associations between smoking and comorbidities in spondyloarthritis. Findings support increased surveillance/caution for patients with PsA or AS with smoking history. ClinicalTrials.gov: NCT01877668/NCT01882439/NCT03486457/NCT01976364/NCT01786668/NCT03502616.

Safety and effectiveness of tofacitinib in Korean adult patients with ulcerative colitis: post-marketing surveillance study

BackgroundTofacitinib is an oral Janus kinase inhibitor for the treatment of ulcerative colitis (UC). We aimed to identify the safety and effectiveness of tofacitinib in patients with UC in routine clinical settings in Korea.MethodsThis open-label, observational, prospective, post-marketing surveillance study was conducted at 22 hospitals in the Republic of Korea. Patients with moderate to severe active UC who received tofacitinib were included and followed up for up to 52 weeks. Tofacitinib was administered at a dosage of 10 mg twice daily for at least 8 weeks, followed by 5 or 10 mg twice daily at the investigator’s discretion based on clinical evaluation according to the approved Korean label. Safety including adverse events (AEs) and effectiveness including clinical remission, clinical response, and endoscopic mucosal healing were evaluated. Safety analysis set was defined as all patients registered for this study who received at least one dose of tofacitinib according to the approved Korean label and followed up for safety data. Effectiveness analysis set included patients in the safety analysis set who were evaluated for overall effectiveness assessment and excluded patients who had received tofacitinib less than 8 weeks.ResultsA total of 110 patients were enrolled, of whom 106 patients were included in the safety population. The median duration of treatment was 370 days and the treatment duration ranged from 16 to 684 days for the safety population. AEs occurred in 42 patients (39.6%). Serious AEs (SAEs) occurred in 7 patients (6.6%) and of them, there were 2 cases of serious infections. These serious infections were reported as Adverse Event of Special Interest (AESI) in this study and no other AESI were reported. There were no cases of death during the study period. Clinical remission rates were 40.0%, 46.7%, 57.6%, and 55.1% at 8, 16, 24, and 52 weeks, and clinical response rates were 77.8%, 87.9%, 56.6%, and 81.4% at each visit, respectively. Endoscopic mucosal healing rates were 58.7% at 16 weeks and 46.2% at 52 weeks.ConclusionTofacitinib was effective in Korean patients with moderate to severe active UC and the safety findings were consistent with the known safety profile of tofacitinib.SummaryThis study confirmed the safety and effectiveness of tofacitinib in Korean patients with moderate to severe active UC in routine clinical settings.Trial registrationThis study is registered in the ClinicalTrials.gov under the identifier NCT04071405, registered on 28 August 2019.

Long-term efficacy and safety of tofacitinib in patients with ulcerative colitis: 3-year results from a real-world study.

The efficacy and safety of tofacitinib for the treatment of refractory ulcerative colitis (UC) has been demonstrated in clinical trials. Although, a series of reports with real-world evidence of its short-term efficacy and safety profiles have already been published, reports of long-term real-world data have been limited. We aimed to show our 3-year evidence on the clinical use of tofacitinib for the treatment of UC, focusing on its efficacy and safety profiles. A retrospective observational study was conducted on patients who started tofacitinib for active refractory UC at our hospital. The primary outcome was the retention rate until 156 weeks after initiating tofacitinib. The secondary outcomes were short-term efficacy at 4, 8, and 12 weeks; long-term efficacy at 52, 104, and 156 weeks; prognostic factors related to the cumulative retention rate; loss of response; and safety profile, including adverse events. Forty-six patients who were able to be monitored for up to 156 weeks after tofacitinib initiation, were enrolled in this study. Continuation of tofacitinib was possible until 156 weeks in 54.3%, with > 50% response rates and > 40% remission rates. Among patients in whom response or remission was achieved and tofacitinib was deescalated after 8 weeks of induction treatment, 54.3% experienced relapse but were successfully rescued by and retained on reinduction treatment, except for 1 patient. No serious AEs were observed in the study. Tofacitinib is effective and safe as long-term treatment in a refractory cohort of UC patients in real-world clinical practice.

Comparative Effectiveness of Upadacitinib and Tofacitinib in Ulcerative Colitis: A US Propensity-Matched Cohort Study.

There are limited real-world data comparing the effectiveness of upadacitinib and tofacitinib in patients with ulcerative colitis (UC). We conducted a retrospective cohort study using TriNetX, a multi-institutional database, to compare the effectiveness of upadacitinib and tofacitinib in patients with UC. The primary aim was to assess the risk of a composite outcome of hospitalization requiring intravenous steroids and/or colectomy within 6 and 12 months. One-to-one propensity score matching was performed for demographics, comorbid conditions, mean hemoglobin, C-reactive protein, albumin, and calprotectin, and prior UC medications including recent oral or intravenous steroid use between the cohorts. Risk was expressed as adjusted odds ratio (aOR) with 95% confidence intervals (CI). There were 526 patients in the upadacitinib cohort (mean age 40.4 ± 16.3, 44.8% female sex, 76.6% White race) and 1,149 patients in the tofacitinib cohort (mean age 42 ± 17.1, 41.9% female sex, 76% White race). After propensity score matching, there was no significant difference in the risk of the composite outcome of need for intravenous steroids and/or colectomy within 6 months (aOR 0.75, 95% CI 0.49-1.09). However, there was a lower risk of the composite outcome (aOR 0.63, 95% CI 0.44-0.89) in the upadacitinib cohort compared with the tofacitinib cohort within 12 months. There was no difference in the risk of intravenous steroid use (aOR 0.70, 95% CI 0.48-1.02) but lower risk of colectomy (aOR 0.46, 95% CI 0.27-0.79). In sensitivity analysis, there was also a lower risk of the composite outcome (aOR 0.64, 95% CI 0.44-0.94), including lower risk of intravenous steroid use (aOR 0.67, 95% CI 0.45-0.99) and colectomy (aOR 0.49, 95% CI 0.26-0.92) in the upadacitinib cohort compared with the tofacitinib cohort within 12 months. This study utilizing real-world data showed that upadacitinib was associated with improved disease-specific outcomes at 12 months compared with tofacitinib in patients with UC.

Impact of Race on the Efficacy and Safety of Tofacitinib in Rheumatoid Arthritis: Post Hoc Analysis of Pooled Clinical Trials.

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 10mg 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)]. Odds ratios (ORs; 95% CI) versus placebo, and placebo-adjusted ∆LS means were calculated for active treatments using logistic regression model and mixed-effect model of repeated measurements, respectively. Safety outcomes were assessed throughout. A total of 6355 patients were included (White, 4145; Black, 213; Asian, 1348; Other, 649). For tofacitinib-treated patients, ORs for ACR20/50/70 responses and CDAI/DAS28-4(ESR) LDA rates through month 3 were generally numerically higher for White/Asian/Other versus Black patients. Across active treatments, trends toward higher placebo-adjusted improvements from baseline in CDAI, DAS28-4 (ESR), HAQ-DI, and Pain (VAS) were observed in Asian/Other versus White/Black patients. Numerically higher placebo responses in Black versus White/Asian/Other patients were generally observed across outcomes through month 12. Safety outcomes were mostly similar across treatment/racial groups. In patients with RA, tofacitinib was efficacious across racial groups with similar safety outcomes; observed racial differences potentially reflect patient demographics or regional practice disparities.

Effectiveness of generic tofacitinib in idiopathic inflammatory myositis (IIM)-a retrospective analysis from Indian Myositis Registry (MyoIN).

Determine domain-based-outcomes and steroid-sparing efficacy of generic tofacitinib in IIM. This is a multicenter retrospective study wherein clinical phenotype, autoantibody profile, prior immunosuppressives, and outcomes at 3, 6, and 12months were retrieved for IIM patients prescribed tofacitinib. Overall clinical response was assessed as complete or partial remission as per physician judgment. Changes in cutaneous and calcinosis domain were recorded as per physician global assessment (PGA), lung domain as per medical research council (MRC) dyspnea scale, and muscle strength by Manual Muscle Testing-8 (MMT-8). Forty-two patients of IIM with mean age 38.7 ± 16years; (76.2% (N = 32) women), median duration of illness 48 (19;88) months were included. Commonest indication for initiating tofacitinib was either for refractory or as steroid sparing for cutaneous domain (N = 25/42, 59.5%) followed by calcinosis (N = 16/42, 38%). Overall complete and/or partial remission was achieved in 23/37 (64.8%), 30/35 (85.7%), and 29/30 (96.6%) patients at 3, 6, and 12months, respectively. At 12-month follow-up, there was a reduction in prednisolone dose, with absolute decrease from a daily dose of 17.5mg (IQR 5;50) to 2.5mg (IQR 0;5) (p < 0.001). Individual domain assessments revealed improvement in cutaneous domain [16/25 (64%)] and calcinosis [6/15 (40%)]. Adverse effects included herpes zoster (N = 2/42, 4.8%) and dyslipidemia (N = 4/42, 9.5%). Treatment with generic tofacitinib significantly reduces the daily dose of corticosteroids and is effective in cutaneous domain including calcinosis in IIM. • This multicenter retrospective study is the first real-world data from India, elucidatingsteroid sparing efficacyof generic tofacitinib in patients with inflammatory myositis. • Domain-based outcome assessment suggests good clinical improvement especially in cutaneous domain, even those with refractory disease. • Modest benefits were evident in calcinosis, but its effect on the muscle and pulmonary domain appears limited.

Risk Stratification of Patients with Psoriatic Arthritis and Ankylosing Spondylitis for Treatment with Tofacitinib: A Review of Current Clinical Data.

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 ≥ 50years 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 ≥ 65years 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 < 65years 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 ≥ 65years, 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.

Enduring Clinical Remission in Refractory Celiac Disease Type II With Tofacitinib: An Open-Label Clinical Study

Refractory celiac disease type 2 (RCDII) is a rare condition with high mortality because of a lack of effective treatment strategies. RCDII is caused by clonal expansion of intraepithelial lymphocytes (IELs). Gain-of-function JAK1 mutations are frequently found in these cells.1,2 In a previous invitro study,3 we demonstrated the potential of tofacitinib, a small-molecule JAK1/JAK3 inhibitor, to control activity of the aberrant IEL population. Here, we report on an open-label prospective pilot study with tofacitinib in patients with therapy-refractory RCDII (EudraCT 2018-001678-10; Dutch Trial Registry [LTR] NL7313). Between November 2019 and February 2022, 4 patients with an established diagnosis of RCDII4 who had failed previous therapies were treated in the Netherlands with tofacitinib 10 mg twice-daily for 12 weeks (Methods; Supporting Documents). Two patients in Germany who fulfilled the inclusion criteria received similar treatment outside this protocol.

Revealing the changes in signaling pathways caused by tofacitinib in patients with rheumatoid arthritis through RNA sequencing and the correlation with clinical parameters.

The current study is to accelerate the understanding of how tofacitinib works in patients with rheumatoid arthritis (RA) due to the lack of relevant information. We selected ten patients with active RA and obtained the expression profile for their peripheral blood mononuclear cells before and after the tofacitinib treatment by RNA sequencing. The gene set enrichment analysis was conducted, and the significantly enriched gene sets were identified. The hub gene highly correlated with clinical parameters in the gene set was selected. We constructed the weighted gene co-expression network, linked modules with clinical indicators, and screened hub genes. The expression of representative hub genes was validated by real-time quantitative PCR (qPCR). Gene set interferon (IFN) α and IFN β signaling was the most significantly down-regulated after tofacitinib treatment. In this gene set, genes Oas2 and Oasl showed a significant positive correlation with morning stiffness. In co-expression network, gene Vgll3 from the violet module with the highest correlation coefficient, was positively correlated with morning stiffness. Among them, Oasl and Vgll3 have shown significant down-regulation in qPCR validation. Our results highlighted the role of type I IFN, mainly including IFN α and IFN β, in the pathogenesis of RA and action for tofacitinib, and provided a new entry point for further elucidating the mechanism of morning stiffness. Key Points • Gene set IFN α and IFN β signaling was the most significantly down-regulated after tofacitinib treatment in RA patients. • Gene Oasl and Vgll3 were correlated with morning stiffness and significantly down-regulated due to the action of tofacitinib. • Type I IFN system was highlighted in the action of tofacitinib.

Effectiveness of Tofacitinib in Patients With Ulcerative Colitis: A Nationwide Veterans Administration Cohort Study.

There is paucity of data on the effectiveness and safety of tofacitinib among elderly patients with ulcerative colitis (UC). Through a retrospective cohort study among the US National Veterans Affairs Healthcare System, we evaluated effectiveness among the elderly (≥65) and young (<65) patients with UC initiated on tofacitinib. Among 158 patients (53 elderly, 105 young), effectiveness at 12 months was 50.94% in the elderly and 33.33% in the young ( P = 0.032). In a nationwide cohort of patients with UC initiating tofacitinib, effectiveness was seen in half of the elderly patients.

Treatment Patterns and Effectiveness of Tofacitinib in Patients Initiating Therapy for Rheumatoid Arthritis: Results From the CorEvitas Rheumatoid Arthritis Registry.

This real-world analysis assessed baseline demographics/characteristics and treatment patterns/effectiveness in patients with rheumatoid arthritis (RA) initiating tofacitinib (TOF) in the US CorEvitas RA Registry. The primary analysis of this study included patients with RA initiating TOF with a 12-month follow-up visit from November 2012 to January 2021. Outcomes included baseline demographics/characteristics and TOF initiation/discontinuation reasons, treatment patterns, and effectiveness (disease activity and patient-reported outcomes [PROs] at 12 months); the primary effectiveness outcome was Clinical Disease Activity Index low disease activity (CDAI LDA). All data, analyzed descriptively, were stratified by TOF regimen (monotherapy vs combination therapy), line of therapy (second- to fourth-line), time of initiation (2012-2014, 2015-2017, or 2018-2020), and dose (5 mg twice daily vs 11 mg once daily). Of 2874 patients with RA who initiated TOF, 1298 had a qualifying 12-month follow-up visit; of these, 43.1% were monotherapy and 66.5% were fourth-line therapy. Overall, tumor necrosis factor inhibitors (40.8%) were the most common treatment immediately prior to TOF initiation. The most common reason for TOF initiation (among those with a reason) was lack/loss of efficacy of prior treatment (67.7%). Overall, at 12 months, 31.9% and 10.1% had achieved CDAI LDA and remission, respectively; 22.4%, 10.4%, and 5% had achieved ≥ 20%, ≥ 50%, and ≥ 70% improvement in modified American College of Rheumatology core set measures, respectively; and improvements in PROs were observed. Effectiveness was generally similar across TOF stratifications. TOF effectiveness (CDAI LDA) was observed in a US real-world setting of patients with RA regardless of TOF regimen, line of therapy, time of initiation, and dose. (ClinicalTrials.gov: NCT04721808).

Real-World Efficacy and Safety of Oral Tofacitinib in Patients with Refractory Moderate to Severe Atopic Dermatitis: A Multicenter Retrospective Study.

Atopic dermatitis (AD) has a complex etiology that includes Th2 polarization, which is accompanied by the cytokines IL4, IL-5, IL-13, and IL-31, as well as Th17 and Th22, and in chronic lesions, Th1 cells. Tofacitinib inhibits Th1-, Th2-, and Th17-associated cytokines by selectively blocking JAK1 and JAK3 receptors. We conducted a multicentric, retrospective chart analysis to study the efficacy and safety of tofacitinib in patients with moderate to severe refractory AD. We included 16 adult patients (aged >18 years) with moderate to severe AD who had previously undergone systemic therapy with inadequate response. In the baseline, demographic data, previous treatment history, severity scores (eczema area and severity index [EASI] and SCORing Atopic Dermatitis [SCORAD]), and quality of life score (Dermatology Life Quality Index [DLQI]) were noted. Baseline blood investigations, including complete blood count, liver function test, renal function test, lipid profile, and interferon gamma release assay for tuberculosis, were done. Patients were followed up every month for 6 months that included documentation of severity scores, blood investigations, and DLQI. Any adverse events, if reported, were noted. All 16 patients completed the 6-month trial. Our patients were previously treated with cyclosporine (n = 10), methotrexate (n = 3), or both (n = 3). The mean EASI scores improved from 23.38 ± 9.56 at baseline to 8.50 ± 7.57 at the end of 6 months. The mean SCORAD score improved from 41.25 ± 8.69 at baseline to 14.93 ± 7.82 at the end of 6 months. Quality of life also improved as the mean DLQI improved from 15.18 ± 2.73 at baseline to 5.31 ± 4.11 at the end of the study period. No severe adverse reactions were noted, but 3 patients experienced dyslipidemia and 2 patients had altered bleeding time. Tofacitinib is a safe and effective treatment option for recalcitrant moderate to severe adult AD.

An Open-Label, Investigator-Initiated, Single-Centre Pilot Study to Determine the Safety and Efficacy of Tofacitinib in Resistant Chronic Spontaneous Urticaria.

Chronic spontaneous urticaria (CSU) is a distressing skin condition characterized by the recurrent appearance of itchy hives. A subset of CSU patients remains resistant to conventional treatment with high-dose antihistamines. Tofacitinib, a Janus kinase inhibitor, has shown promise in various inflammatory skin diseases. We aimed to evaluate the efficacy of oral tofacitinib in patients with CSU resistant to antihistamines. This study examined data retrospectively from seven patients who were diagnosed with CSU and were treated with tofacitinib for at least six months. These patients initially exhibited resistance to treatment with four-fold up-dosed antihistamines. One of the patients was already on omalizumab, and another was tried on cyclosporine. The patients were administered oral tofacitinib at a dosage of 5 mg twice daily for six months. Patients were followed up monthly for disease control and side effects. The response to treatment was evaluated using the urticaria activity score over 7 days (UAS7) and urticaria control test (UCT). Paired t-tests were conducted to determine the statistical significance of the results using SPSS version 25 software. Six out of the seven patients demonstrated a significant improvement in both UAS7 and UCT scores after six months of treatment with oral tofacitinib. The mean UAS7 score decreased from 24.86 at baseline to 3.83 at the study endpoint (P < 0.0001). Similarly, the mean UCT score increased from 0.57 at baseline to 14 at the study endpoint (P < 0.0001). The standard deviations for both measures were 4.85 and 0.98 at baseline and 3.1 and 3.1 at the study endpoint for UAS7 and UCT, respectively. In this six-month follow-up study, oral tofacitinib demonstrated significant efficacy in treating CSU patients' resistant to high-dose antihistamines. Most patients experienced a remarkable reduction in urticaria activity and an improvement in disease control. These findings suggest that tofacitinib holds promise as a potential therapeutic option for this challenging subset of CSU patients. However, larger, randomized controlled trials are warranted to further investigate the long-term safety and effectiveness of tofacitinib in this population.

P760 Post-marketing surveillance of tofacitinib in patients with ulcerative colitis in Japan: A final report of effectiveness and safety data

Abstract Background Tofacitinib is an oral Janus kinase inhibitor for the treatment of ulcerative colitis (UC). We present the final analysis of a 60-week post-marketing surveillance (PMS) study of tofacitinib in patients (pts) with UC in Japan. Methods A final analysis of safety and effectiveness data from a PMS study was conducted (final data as of 30 September 2022). All pts with UC in Japan receiving tofacitinib were registered. All adverse drug reactions (ADRs) during tofacitinib treatment were recorded. Data were excluded for 13 pts from 2 hospitals that did not obtain pt consent and were therefore not permitted for publication. In the risk-management plan, several ADRs were identified as clinically important events or as potential risks, for which all treatment-period data were used to calculate cumulative incidence rates (IRs; unique pts with events per 100 pt-years [PY] of exposure). Effectiveness was assessed by partial Mayo score as observed. Results In total, 2043 pts receiving tofacitinib were enrolled in the PMS study, of whom 1982 and 1969 were included in the final safety and effectiveness analyses, respectively. In total (safety analysis set), 60.5% of pts were male and mean age was 42.5 years, with 2706.4 PY of exposure. ADRs and serious ADRs were observed in 462 (23.3%) and 46 (2.3%) pts, respectively; one death occurred due to an intestinal abscess (not related to study drug per investigator’s assessment). Herpes zoster (HZ; non-serious/serious) was the most commonly reported infection (89 pts [4.5%]). The IRs of malignancy, cardiovascular events and venous thromboembolic events were all &amp;lt;0.5 per 100 PY of exposure (Table). At Week 60, 735 of 870 ongoing pts (84.5%) were in remission (Figure). Overall, 1038/1982 pts (52.4%) discontinued treatment, most commonly due to inadequate clinical response (508/1038 pts [48.9%]). Conclusion In this final analysis, the overall safety profile during the treatment period from PMS reports of tofacitinib in pts with UC in Japan was generally comparable with tofacitinib safety data previously reported in PMS reports from Japan and worldwide,1 and in the tofacitinib UC clinical programme.2 However, rates of HZ were higher in this final analysis than in the tofacitinib UC clinical programme.2 Tofacitinib was effective in Japanese pts with UC in a clinical practice setting. The majority of pts with evaluable partial Mayo scores achieved remission during the 60-week observation period, consistent with previously reported data from the tofacitinib UC clinical programme.2

P943 Real world Effectiveness and safety of tofacitinib in patients with Ulcerative Colitis: 6 months follow-up of the French TOFAST study

Abstract Background TOFAST is an observational, prospective, multicenter cohort study aiming to describe the real-life clinical benefit of tofacitinib in moderate-to-severe Ulcerative Colitis (UC). Methods We report the results of the interim analysis after 6 months of follow-up, describing patient's characteristics, effectiveness, including change in daily PRO2 scores [RB and stool frequency (SF)] during the first 14 days and the median time to relief, and safety. Clinical response was defined as a decrease in partial Mayo score (PMS) (≥ 3 points and ≥30%) from inclusion with a concomitant decrease in rectal bleeding (RB) subscore ≥ 1 point (absolute subscore of 0 or 1). Clinical remission was defined as PMS ≤2 with no subscore &amp;gt;1. Symptomatic relief was reported by patients as the time in days from initiation of tofacitinib to improvement of their symptoms. Safety has been been reported as the % of Adverse Events (AE), serious AE and AE of special interest. Results 88 patients were included in the safety analysis (one patient was excluded from the effectiveness analysis as he did not meet the eligibility criteria) with a median exposure duration of 11.7 [Q1; Q3: 6.0; 22.1] months. Of these patients, 67 completed a 6-month follow-up visit by 15/07/2023 and were included in the effectiveness analysis. At inclusion 59.8% of patients were male with a mean (± SD) age of 37.5 ±13.2 years, a median disease duration of 5.9 years [Q1; Q3: 2.7; 13.1]. 46.5% of patients had pancolitis. The mean total Mayo Score was 8.1 ±2.4. 94.3% of patients had previously received at least one anti-TNF agent, 67.8% vedolizumab and 35.6% ustekinumab. Tofacitinib was initiated at 10 mg b.i.d, in combination with corticosteroids for 35.6% of patients. At 6 months, 53 (77.9%) patients were still treated with tofacitinib, 58.5% at 10 mg BID dose. Corticosteroids were ongoing in 22.9% of patients. Clinical response and remission were observed in 64.2% and 61.2% of patients, respectively. For the 68 (78.2%), patients who reported improvement the median time to relief was 7 days [Q1; Q3: 3.5 ;14.5]. PRO2 scores normalization during the first 14 days is shown in the figure. 84.1% of patients reported at least one adverse event (AE) and 21.6% reported at least one serious AE. Seventeen (19.3%) infections and 3 (3.4%) cases of herpes zoster were observed as well as one non-invasive low-grade urothelial carcinoma. No major cardiovascular or venous thromboembolic event, nor malignancy or death were observed (Table). Conclusion In this real-life cohort of patients with refractory UC, tofacitinib induced a clinical response and remission in over 60% of patients, with symptoms relief observed as early as the first two weeks. AEs were consistent with the known tofacitinib safety profile.

P636 Comparison of the real-world efficacy of filgotinib with tofacitinib in patients with refractory ulcerative colitis: A single-center retrospective study

Abstract Background Several Janus kinase inhibitors have recently been launched for the treatment of ulcerative colitis (UC). However, there are few reports comparing the efficacy and safety of each drug in patients with refractory UC, especially with filgotinib (FIL), which was recently launched and can be concomitantly used with thiopurines. We herein aimed to compare the real-world efficacy and safety of tofacitinib (TOF) and FIL in induction therapy for patients with refractory UC. Methods Patients with refractory UC, who received either TOF 20mg/day or FIL 200mg/day from May 2018 to October 2023 in Hyogo Medical University Hospital were included in this study. Primary outcomes were clinical response rates at 2, 4, and 8 weeks after administration of TOF or FIL. Clinical response was defined as a decrease of partial Mayo Score (pMS) of ≥2 from baseline and rectal bleeding subscore is ≤1 or a decrease of ≥1 from baseline. Secondary outcomes were cumulative incidences of adverse events during the observation period. Results Of the 230 refractory patients with UC, 197 received TOF and 33 received FIL treatment. The median age was 37 [IQR 27–49] and 49 [33–54] years, and the median disease duration was 3 [1–10] and 5 [2–10] years, respectively. Median durations of observation were 118 [52–188] weeks in the TOF group and 41 [29–60] weeks in the FIL group, median baseline pMS were 6 [5–7] and 5 [5–6], and serum CRP levels were 3.8 [1.3–12.3] and 1.8 [0.3–3.3] mg/L, respectively. Thirty-eight (19.3%) patients in the TOF group and 3 (9.0%) patients in the FIL group received systemic steroids, and 8 (24.2%) in the FIL group received thiopurine at baseline. The clinical response rates at 2, 4 and 8 weeks were 58.4%, 59.4% and 62.9% in the TOF group, and 42.4%, 57.6% and 48.9% in the FIL group, respectively, and the rate tended to be higher in the TOF group than in the FIL group at 2 weeks (p = 0.092). Of the patients who did not respond at 4 weeks, the TOF group had a significantly higher clinical response rate (31.3%) than the FIL group (0%) at 8 weeks (p = 0.032). Among 124 patients with prior anti-TNF-α antibody failure, 59.6% (65/109) of patients in the TOF group and 46.7% (7/15) in the FIL group achieved comparable clinical responses at 8 weeks (p = 0.407). Fifteen of 197 (7.6%) patients in the TOF group and 2 of 33 (6.1%) in the FIL group did not continue treatment until 8 weeks due to adverse events, but there were no significant differences between the groups. Conclusion Even in patients without a response for up to 4 weeks, TOF treatment may provide a higher clinical response than FIL treatment at 8 weeks.

P562 Safety and persistence oh the first JAK inhibitor Tofacitinib in patients with ulcerative colitis

Abstract Background A drug safety warning was published in 2021 about the risks associated with tofacitinib, which were found in the Oral-Surveillance study. The European Medicines Agency (EMA) and the Spanish Agency for Medicines and Medical Products (AEMPS) have recommended, due to this warning, some precautions in the prescriptions: It should not be used in patients older than 65 years of age, people who are current or past smokers, or individuals with cardiovascular or malignancy risk factors unless there are no suitable treatment alternatives. The aim fo this study was to assess the safety and treatment persistence of tofacitinib in clinical practice in three Spanish third-level hospitals. Methods Retrospective observational multicenter study of patients with Ulcerative Colitis (UC) treated with tofacitinib from January 2019 to October 2023. Sex, age, line of treatment, persistence, adverse events, discontinuations and risk factors associated with the warning were evaluated. Information was collected from the hospital’s information systems. Results A total of 56 patients, 53% women, mean age 55 (18-72) years old. Tofacitinib was the first line treatment in 2% of the patients after loss of response to the conventional treatment, second line for 57%, third line for 30% and fourth line for 11% after biological drugs (infliximab, adalimumab, vedolizumab and ustekinumab). 52% of patients needed maintenance with the higher doses (10mg dose) after induction due to the lack of response with the 5 mg dose, with an average of 52 weeks. The mean persistence was 18 months (1-56), with 19,6% discontinuations due to primary failure and secondary failure. It must be noted that one patient, who received tofacitinib for three years, underwent appendicular neoplasia and finally died due to liver metastases. There was not discontinuation due to other adverse events, which were: 3,6% herpes zoster, 46,4% increased total cholesterol level &amp;gt;200 mg/dl (compared with the initial measurement), of which 19% received statins.There were 27 (48%) patients with risk factors associated with the safety warning: 37% cardiovascular risk, 3,7% older than 65 years, 11,1% previous malignancy, 18,5% current or past smokers and 29,6% had several of these risks. Conclusion In this multicenter real-world treatment-refractory UC population cohort, tofacitinib was well tolerated in the long term, even in the patients with risk factors related to the warning.

Tofacitinib in Patients Hospitalized With Moderate and Severe COVID-19: Not Just Another Kinase Inhibitor.

Background There has been an intense search for pharmacological agents that can complement corticosteroid therapy in the treatment of severe coronavirus disease 2019 (COVID-19). The Janus kinase inhibitor tofacitinib has shown promise in this regard. This study aimed to determine the impact of adding tofacitinib to standard care on the mortality and totalduration of hospital stay in severe COVID-19. Methodology This retrospective study compared the mortality and total duration of hospital stay among patients admitted with severe COVID-19 to a designated COVID-19 hospital in south India who had received tofacitinib in addition to standard care versus standard care alone. Medical case records of severe COVID-19 patients were retrieved and screened for inclusion. Categorical variables such as mortality were expressed as proportions and compared using the chi-square test, while continuous variables such as total duration of hospital stay were compared via the independent t-test. The odds ratio (OR) was calculated for the mortality difference between the two groups. P-values ≤0.05 were considered significant. Results Following the initial screening of 250 medical records, 186 patients were included in the final analysis, of whom 103 had received tofacitinib and 83 had received standard care. There was no significant difference in mortality between the two groups (OR = 1.58 (95% confidence interval = 0.71 to 3.51); p = 0.26). The total duration of hospital stay was significantly longer among those in the tofacitinib group (17.14 ± 8.85 days vs. 14.04 ± 5.48 days; p = 0.01). Conclusions Tofacitinib did not improve the clinical outcomes when used to supplement corticosteroids in the treatment of severe COVID-19.
