Abstract Background A significant proportion of patients with moderate to severe ulcerative colitis (UC) do not respond to therapy, which includes thiopurines, glucocorticoids, and antagonists to tumour necrosis factor-α and integrin. Tofacitinib, a Janus Kinase inhibitor, has emerged as an efficacious and safe treatment for moderate to severe ulcerative colitis. However, it is not known if this efficacy translates into real-life effectiveness in a regular clinical practice. Aims We aimed to assess the rate of clinical response and clinical remission at 3 and 6 months after tofacitinib initiation. Secondary endpoints included rate of biomarker normalization, corticosteroids-free clinical remission and severe infections. Methods We conducted a multi-center retrospective observational study of adult patients with active UC started on tofacitinib from January 1, 2015 to October 1, 2019 at the McGill University Health Center and Hotel-Dieu de Lévis. A positive clinical response was defined as a decrease of ≥3 in the partial Mayo score. Clinical remission was defined as partial Mayo score of ≤2. Biomarker normalization was defined as fecal calprotectin ≤250ug/g. Severe infection was defined as an infection requiring hospitalization. Results During the study period, 40 patients with UC were started on tofacitinib. Amongst the patients, 85% (n=34) had failed ≥1 biologic and 50% (n=20) had failed ≥3 biologics. At the time of this preliminary analysis, 38 patients had undergone 3 months of treatment and 30 patients had undergone 6 months of treatment. At 3 months, a clinical response was seen in 89.5% of patients (n=34) and clinical remission occurred in 63.2% (n=24). At 6 months, clinical response occurred in 73.3% of patients (n=22) and clinical remission was sustained in 53.33% (n=16). Biochemical normalization occurred in 29.0% (n=11) and 30.0% (n=9) at 3 and 6 months, respectively. Additionally, 63.2% (n=24) and 43.3% of patients (n=13) achieved steroid-free clinical remission at 3 and 6 months, respectively. In the interim, one patient developed a serious infection requiring discontinuation of drug. Conclusions Our preliminary analysis demonstrates that in a real-life setting, tofacitinib is an effective treatment for inducing clinical remission in refractory UC patients. Further data will be complied to better assess the efficacy over a longer follow up. Funding Agencies None

We conducted a multi-centre retrospective observational study of adult patients with active UC started on tofacitinib from January 1, 2015 to October 1, 2019 at the McGill University Health Center and Hotel-Dieu de Lévis. A positive clinical response was defined as a decrease of ≥3 in the partial Mayo score. Clinical remission was defined as partial Mayo score of ≤2. Biomarker normalisation was defined as faecal calprotectin ≤250 μg/g. Severe infection was defined as an infection requiring hospitalisation. Results During the study period, 40 patients with UC were started on tofacitinib at 10 mg/kg twice a day. Amongst the patients, 85% (n = 34) had failed ≥1 biologic and 50% (n = 20) had failed ≥3 biologics. At the time of this preliminary analysis, 38 patients had undergone 3 months of treatment; 30 patients had undergone 6 months of treatment.

Abstract Background Tofacitinib is an orally active, small-molecule Janus kinase inhibitor, recently approved for the treatment of moderate to severe ulcerative colitis (UC) refractory to corticosteroid. However, currently, there is inadequate evidence for efficacy of Tofacitinib in UC patients. Therefore, our objective was to evaluate the efficacy and safety of Tofacitinib for inducing and maintaining remission in UC patients. Methods In a single-centre retrospective setting, 71 consecutive patients with UC who had failed to respond to corticosteroid or biologics were included. All patients had received 10mg Tofacitinib orally twice daily for at least 8 weeks as remission induction therapy and then, the responders received 5mg twice daily as maintenance therapy for up to 26 weeks. The clinical response and adverse events were evaluated at weeks 8 (induction) and 26 (maintenance). UC activity was assessed by the partial Mayo score. Clinical remission was defined as p-Mayo score ≤1 and the bleeding subscore = 0. Clinical response was defined as p-Mayo score ≤4 and a decrease of ≥3 points relative to baseline. Furthermore, the cumulative remission rates up to 26 weeks were determined by the Kaplan–Meier survival analysis. Results At week 8, 24 of 71 patients (33.8%) achieved clinical remission and 20 (28.2%) achieved response level. The mean p-Mayo score fell from 5.8 ± 1.1 at entry to 3.5 ± 2.3 at week 2 (p < 0.01) and 2.3 ± 1.9 at week 8 (P<0.01). The average total cholesterol increased from 180.8 ± 36.0 mg/dl at entry to 206.8±39.3 mg/dl (p < 0.01). In anti-tumour necrosis factor (TNF)-α or vedolizumab (VDZ) naïve subgroup (n = 14), 8 patients (57.1%) achieved response level, while in biologic failure subgroup (n = 57), 36 patients (63.2%) achieved response level. In single biologic failure subgroup (n = 27), 19 patients (70.4%), in double biologics failure subgroup, 14 of 24 patients (58.3%), and in 3 biologics failure subgroup, 3 of 6 patients (50.0%) achieved response level, showing a decrease in the efficacy of Tofacitinib in patients who had failed more than one biologic. Furthermore, of the 25 patients followed for 26 weeks, 23 (92.0%) sustained remission at week 16 and 19 (76.0%) at week 26. Herpes virus infection occurred in 4 patients. The increase in total cholesterol was observed in 68.8% of the patients. Conclusion Our retrospective efficacy assessment indicated that Tofacitinib was effective and safe for inducing and maintaining remission in corticosteroid refractory UC patients, regardless of biologic naïve or failure background. The efficacy of 10mg twice daily was rapid and observed within 2 weeks of starting the treatment.

Abstract Background Tofacitinib (TFC) is an oral, small-molecule Janus kinase inhibitor, which was recently approved for moderate to severe ulcerative colitis (UC). The aim of the current real-life study was to determine efficacy of TFC induction therapy regarding the clinical response and remission in patients with active UC. We evaluated short-term efficacy data in a Hungarian cohort with prior exposure to other biological agents such as anti-TNF drugs and vedolizumab. Methods In this single-centre retrospective study, patients with TFC introduction were included. Since January 2019, a total of 16 patients received an oral TFC induction therapy in a dose of 10 mg twice daily for 8 weeks. Endoscopic activity was evaluated by endoscopic Mayo (eMayo) score before the introduction of TFC and in case of an inadequate therapeutic response to the 5-mg-therapy to confirm therapeutic decision-making. Based on the evaluation of clinical symptoms and laboratory parameters, we either kept the dosage or reduced the dose to 5 mg according to local regulations. We also collected data from the 16. and 24. weeks of the therapy. Primary endpoints were a clinical response (as a reduction in partial Mayo Score [pMayo] by minimum 3 points) or remission (as a Mayo score of the maximum of 2 points and without blood in stool) at week 8. Results Sixteen patients had received the induction therapy (mean age: 36 years, 7 males and 9 females) in our centre. After 8 weeks, 12 (75%) patients responded to the TFC induction therapy and 6 (37.5%) of them were in remission. Four patients were primary non-responders (25%). Corticosteroid therapy (18 ± 7 mg) was required during the induction in 4 responder cases, which could be stepped down by week 8. As a continuous maintenance therapy, 4 patients have already reached the 16th week and 8 have completed the 24th week. By the end of the follow-up, 12 patients responded and 10 was in remission. During the observation period, 3 patients had to remain on 10 mg TFC dose, 6 patients required dose escalation from 5 mg to 10 mg and 5 mg was sufficient in case of only 3 patients after the introduction. Endoscopic activity showed a moderate decrease from 2.5 ± 0.5 eMayo score to 2 ± 1 (n = 7) until week 16. In respect the responder patients, CRP levels decreased from the mean of 7.23 to 5.02. No serious side-effects were observed during the follow-up. Conclusion After the 8-week TFC induction therapy, the response rate was high and only every fourth patients were non-responder. A low number of patients had adequate reactions to the 5 mg-therapy after the introduction, but TFC is effective with dose-escalation in respect of clinical response and remission in patients with UC, who have had an inadequate response to previous biological therapy.

Abstract Background An unmet therapeutic need remains in patients with ulcerative colitis (UC). U-ACHIEVE is one of two phase 3 induction trials evaluating the safety and efficacy of the selective Janus kinase–1 inhibitor upadacitinib (UPA) 45 mg once daily (QD) in adults with UC. Methods U-ACHIEVE is a multicentre, double-blind, placebo (PBO)–controlled trial (NCT02819635) that randomized patients with moderately to severely active UC 2:1 to UPA 45 mg QD or PBO for 8 weeks. Patients were stratified by response to biologic therapy (inadequate vs non–inadequate responder), baseline corticosteroid use (yes or no), and baseline adapted Mayo score (≤7 or >7). The primary endpoint was proportion of patients achieving clinical remission (per adapted Mayo Score) at week 8.Ranked secondary endpoints included endoscopic improvement, endoscopic remission, and clinical response per adapted Mayo Score at week 8; clinical response per partial adapted Mayo Score at week 2; and histologic-endoscopic mucosal improvement at week 8. Non-responder imputation incorporating multiple imputations for missing data due to COVID-19 are reported. Safety was assessed through week 8. Results 474 patients were randomized (UPA, n=319; PBO, n=155). Baseline characteristics were well balanced between groups (Table 1). A significantly higher proportion of patients receiving UPA (26.1%) vs PBO (4.8%) achieved clinical remission at week 8 (adjusted treatment difference [95% CI], 21.6% [15.8, 27.4]; P<0.001; Figure 1). For all ranked secondary endpoints, UPA was superior to PBO (P<0.001; Figure 1). A significant difference in clinical response favouring UPA vs PBO was seen as early as week 2 (60.1% vs 27.3%) and was sustained over 8 weeks (79.0% vs 41.6%; Figure 2). There were more serious adverse events (AEs), severe AEs, and AEs leading to study drug discontinuation with PBO (Table 2). The most common AEs were acne, creatine phosphokinase elevation, and nasopharyngitis with UPA and worsening of UC and anaemia with PBO. Incidence of serious infection was similar between UPA and PBO. Neutropenia and lymphopenia were reported more frequently with UPA vs PBO (Table 2).No adjudicated gastrointestinal perforation, major cardiovascular AEs, or thrombotic events and no active tuberculosis, malignancy, or deaths were reported. Conclusion In patients with moderately to severely active UC, UPA 45 mg QD induction therapy was superior to PBO in inducing clinical remission/response, and endoscopic remission/response over 8 weeks; responses were significant and rapid. UPA 45 mg QD was well tolerated; safety was comparable with the known safety profile of UPA, and no new safety signals were identified.

Background and Aims: Several studies have found Golimumab (GOL) effective and safe in the short-term treatment of ulcerative colitis (UC), but few long-term data are currently available from real world. Our aim was to assess the long-term real-life efficacy and safety of GOL in managing UC outpatients in Italy. Methods: A retrospective multicenter study assessing consecutive UC outpatients treated with GOL for at least 3-month of follow-up was made. Primary endpoints were the induction and maintenance of remission in UC, defined as Mayo score ≤2. Several secondary endpoints, including clinical response, colectomy rate, steroid free remission and mucosal healing, were also assessed during the follow-up. Results: One hundred and seventy-eight patients were enrolled and followed up for a median (IQR) time of 9 (3-18) months (mean time follow-up: 33.1±13 months). Clinical remission was achieved in 57 (32.1%) patients: these patients continued with GOL, but only 6 patients (3.4%) were still under clinical remission with GOL at the 42nd month of follow-up. Clinical response occurred in 64 (36.4%) patients; colectomy was performed in 8 (7.8%) patients, all of them having primary failure. Steroid-free remission occurred in 23 (12.9%) patients, and mucosal healing was achieved in 29/89 (32.6%) patients. Adverse events occurred in 14 (7.9%) patients. Conclusions: Golimumab does not seem able to maintain long-term remission in UC in real life. The safety profile was good.

Abstract Background The pan-Janus kinase inhibitor tofacitinib (TFC) has recently been approved for treatment moderate-to-severe ulcerative colitis (UC). Real-life data are limited, especially on endoscopic and histologic outcome. We report the efficacy and safety of TFC in refractory UC patients, and assessed potential clinical predictors of response. Methods Thirty-five UC patients, all refractory to anti-TNF and vedolizumab, were prospectively included (Table 1). All received TFC 10mg BID till week 8, and were endoscopically assessed at baseline (Mayo endoscopic sub-score ≥2) and week 8. Biological response was defined as a 50% decrease in faecal calprotectin (fCal) or fCal <250 mg/g, and biological remission as a fCal <250 mg/g at week 8. The endoscopic response was defined as Mayo endoscopic sub-score of ≤1, endoscopic remission as a sub-score of 0. Histologic remission was defined as a numeric Geboes score ≤6 (similar to ≤2A.0). A non-response imputation and last observation carried forward analysis was applied. Results The Mayo endoscopic sub-score decreased significantly by week 8 (p = 0.004), resulting in an endoscopic response and remission rate of 22.9% and 17.2% respectively. Histological remission was seen in 14.8% of patients. Faecal calprotectin decreased from 1386 mg/g down to 568 mg/g by week 4 (p = 0.03) (Table 2), but not further down by week 8 (703 mg/g, p = 0.5) with a biological response and remission rate of 52.9% and 38.2%. Half of the patients with a PNR to one anti-TNF (10 out of 20) did discontinue TFC because of PNR. However, PNR to two anti-TNF agents almost exclusively (4 out of 5) resulted in PNR to TFC. In contrast, only 3 out of 8 vedolizumab PNR experienced PNR to TFC. Ultimately, 48.6% of all included patients discontinued TFC therapy after a median of 15.9 [12.4–26.6] weeks, all but one due to PNR, of whom 9/17 (52.9%) required colectomy. In multivariate analysis, a higher baseline albumin and a lower Mayo endoscopic sub-score were independent predictors of endoscopic (OR 1.06, p = 0.02; OR 0.59, p = 0.003) and biological remission (OR 1.06, p = 0.03; OR 0.57, p = 0.01). By week 8, creatinine kinase significantly increased (p = 0.001), whereas the lipid profile was not significantly affected. One patient suffered from vaginal herpes infection, and one patient treated with TFC and high dose steroids developed disseminated nocardia, pneumocystic jiroveci, cutaneous zoster and varicella pneumoniae. Conclusion TFC can induce biologic, endoscopic and histologic remission in refractory UC, though clinical and predictive molecular markers are required to identify the right patients. In patients with prior PNR to 2 anti-TNF agents, TFC does not seem an alternative treatment strategy.

Abstract Background Tofacitinib is a partially selective Janus kinase inhibitor approved for the treatment of refractory moderate to severe ulcerative colitis [UC]. We sought to define the effectiveness and adverse effects of tofacitinib in a real-world cohort. Methods We conducted a retrospective observational cohort study of 134 patients with UC [64% male; median age 37 years [range 16–81]; 83% of patients had previously received at least one biologic] treated with tofacitinib from October 2018 to October 2019 in four UK centres. Disease activity was assessed using the Simple Clinical Colitis Activity Index [SCCAI] or partial Mayo score [PMS], depending on study site. Response and remission were defined as a reduction in SCCAI or PMS of ≥3and SCCAI ≤2 or a PMS ≤1, respectively. Results Overall, 74% (88/119; 95 confidence interval [CI] 65–81%] patients responded to tofacitinib at Week 8 and steroid-free remission was observed in 44% [47/108; 95% CI 3453%] patients at Week 26. Primary non-response was independently associated with younger age [p = 0.014] and higher C-reactive protein [CRP] levels at baseline [p = 0.004]. Only 23% [3/13] of patients who continued tofacitinib in the setting of primary non-response were in steroid-free remission at Week 26. Prior biologic exposure did not influence response or remission rates. Dose escalation, however, recaptured response in approximately half of patients who had lost response. Dyslipidaemia was observed in 20% [27/134; 95% CI 1428%] of patients, but adverse events necessitating drug withdrawal were uncommon and no venous thromboembolic events occurred. Conclusions In this multicentre real-world cohort, tofacitinib was well tolerated and clinically effective in a treatment-refractory UC population.

Abstract Background Long-term real-life data on the efficacy of the Janus kinase inhibitor tofacitinib in moderate-to-severe ulcerative colitis (UC) are limited. We here report efficacy of tofacitinib in refractory UC patients with an emphasis on endoscopic and histologic outcome. Methods Fifty-four consecutive UC patients (Mayo endoscopic sub-score ≥2) initiating tofacitinib in 2 tertiary IBD referral centres were prospectively included (Table 1). Almost all were refractory to both anti-TNF (96.4%) and vedolizumab (92.7%) and received tofacitinib in standard dosage. Steroid-free clinical remission was defined as partial Mayo score of ≤2 with no single sub-score >1 and without any steroid exposure at assessment. Biological remission was defined as faecal calprotectin <250mcg/g, endoscopic remission as Mayo endoscopic sub-score of 0, endoscopic improvement as Mayo endoscopic sub-score of ≤1, and histologic remission as Nancy histology index of 0. A combination of endoscopic and histologic remission was referred as mucosal healing. All outcomes were assessed at year 1. Non-responder imputation and last observation carried forward analysis were applied. Results Patients were followed for a median [IQR] of 91.7 [67.2–102.4] weeks, with an exposure to tofacitinib of 23.9 [14.6–51.6] weeks. By year one, 31.5% of patients were in steroid-free clinical remission (Figure 1). Biological remission was observed in 26.9% of patients. Endoscopic improvement, endoscopic remission, histologic remission and mucosal healing, were observed in 31.5%, 24.1%, 22.0% and 18.0% of patients, respectively. Multivariate analysis identified baseline Mayo endoscopic sub score (OR 0.03, p=0.03); endoscopic improvement by week 16 (OR 36.5, p=0.008) and disease extent (OR 0.11, p=0.05) as independent predictors for endoscopic remission at year 1. Patients with left-sided colitis or proctitis experienced higher endoscopic remission rates (33.3% and 25.0%) then patients with extensive colitis (10.5%, p=0.09; p=0.6). Ultimately, 61.1% of all patients discontinued tofacitinib therapy after a median of 15.9 [9.2–24.5] weeks, due to primary non-response (n=25), loss-of-response (n=6) or (serious) adverse events (n=2). Thirteen patients (24.1%) required colectomy. During follow-up, no venous thrombo-embolisms or cancers were observed. One patient had to be admitted at ICU due to several life-threatening opportunistic infections. Conclusion In this highly refractory cohort of UC patients, tofacitinib induced and maintained endoscopic and histologic remission in up to one quarter of patients. UC patients with moderate left-sided colitis and proctitis had a numeric higher likelihood for a sustained effect than patients with extensive colitis.

Abstract Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Efficacy and safety of tofacitinib were demonstrated in patients with moderate to severe UC in 3 Phase 3 studies.1 Here, we present data from an ongoing, open-label, long-term extension (OLE) study.2 Methods We present updated safety and efficacy data from the OLE study (OCTAVE Open, NCT01470612; as of May 2019, database not locked). Eligible patients included non-responders (Week 8 data) in OCTAVE Induction 1 and 2 (NCT01465763; NCT01458951) and completers (Week 52 data) or treatment failures (early-termination data) in OCTAVE Sustain (NCT01458574). Patients in remission (total Mayo score ≤2, no individual subscore >1, rectal bleeding [RB] subscore 0) at Week 52 of OCTAVE Sustain (central read) received tofacitinib 5 mg twice daily (BID); all others received 10 mg BID. Induction non-responders without clinical response (≥3-point and ≥30% decrease from induction study baseline total Mayo score, plus ≥1-point RB subscore decrease or absolute RB subscore ≤1) at Month 2 of the OLE study were withdrawn. Incidence rates (IRs) for adverse events (AEs) of special interest were calculated (no. of unique patients with events per 100 patient-years). Efficacy endpoints were derived from Mayo score (local read) with non-responder and last observation carried forward imputation (NRI-LOCF) [a]. Results Of 944 patients who received ≥1 dose of tofacitinib, 769 (81.5%) received 10 mg BID (median duration [range]: 5 mg BID 1170 [36–2066]; 10 mg BID 668 [1–2159] days). In total, 338 (35.8%) and 93 (9.9%) patients discontinued due to insufficient clinical response and AEs (excl. worsening UC), respectively. IRs (95% confidence interval) in the Tofacitinib. All group were: deaths 0.18 (0.05, 0.47); serious infections 1.57 (1.08, 2.19); herpes zoster (non-serious and serious) 3.27 (2.54, 4.14); major adverse cardiovascular events 0.14 (0.03, 0.40); malignancies excl. non-melanoma skin cancer (NMSC) 0.92 (0.56, 1.42); NMSC 0.74 (0.43, 1.21); deep vein thrombosis 0.05 (0.00, 0.25); pulmonary embolism 0.18 (0.05, 0.47) (Table). At Month 36 (NRI-LOCF), 58.9% (n = 103) and 33.5% (n = 257) were in remission, 64.6% (n = 113) and 37.0% (n = 284) had mucosal healing (Mayo endoscopic subscore of 0 or 1) [b] and 66.9% (n = 117) and 40.2% (n = 309) showed clinical response, in the 5 and 10 mg BID groups, respectively. Conclusion Incidence of AEs remained generally consistent in patients with moderate to severe UC in the OLE study compared with a previous analysis.2 Data continue to support long-term efficacy with tofacitinib up to 36 months beyond Week 52 of OCTAVE Sustain.
