Project description:BackgroundTofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis. We present final data from OCTAVE Open, an open-label, long-term extension study.AimsThe primary objective of OCTAVE Open was to assess the safety and tolerability of long-term tofacitinib in patients with ulcerative colitis; evaluating efficacy was a secondary objective.MethodsEligible patients included OCTAVE Induction 1&2 non-responders and OCTAVE Sustain completers/treatment failures. Patients in remission at OCTAVE Open baseline received tofacitinib 5 mg b.d.; all others received 10 mg b.d. Incidence rates (unique patients with events/100 patient-years) for adverse events of special interest were calculated; ≤7.0 years of observation. Efficacy endpoints derived from Mayo score were reported ≤36 months (last scheduled endoscopy visit).ResultsIn OCTAVE Open, 769 of 944 patients (81.5%) initially received tofacitinib 10 mg b.d. Among all patients (2440.8 patient-years of exposure), incidence rates (IRs; 95% confidence intervals) for deaths and adverse events of special interest were: deaths, 0.25 (0.09-0.54); serious infections, 1.61 (1.14-2.20); herpes zoster (non-serious and serious), 3.16 (2.47-3.97); opportunistic infections, 0.87 (0.54-1.33); major adverse cardiovascular events, 0.16 (0.04-0.42); malignancies (excluding non-melanoma skin cancer), 1.03 (0.67-1.52); non-melanoma skin cancer, 0.75 (0.45-1.19); deep vein thrombosis, 0.04 (0.00-0.23); pulmonary embolism, 0.21 (0.07-0.48). At Month 36, 66.9% and 40.3% showed clinical response, 64.6% and 37.1% had endoscopic improvement, and 58.9% and 33.7% maintained or achieved remission, with tofacitinib 5 and 10 mg b.d. respectively.ConclusionTofacitinib demonstrated consistent safety up to 7.0 years. Data collected up to Month 36 support long-term efficacy beyond the 52-week maintenance study.

Project description:Background and aimsEtrasimod is an oral, selective, sphingosine 1-phosphate receptor modulator. In a phase 2, randomised, double-blind, placebo-controlled trial in adults with moderately-to-severely active ulcerative colitis [OASIS], etrasimod 2 mg provided significant benefit versus placebo and was generally well tolerated. This open-label extension [OLE] evaluated safety and efficacy of etrasimod for up to 52 weeks.MethodsIn OASIS, 156 patients received etrasimod 1 mg, etrasimod 2 mg, or placebo, once daily for 12 weeks. After completing OASIS, patients could enrol in the OLE and receive etrasimod 2 mg for an additional 34-40 weeks.ResultsIn all, 118 patients enrolled in the OLE; 112 patients received etrasimod 2 mg at any point and were evaluated for safety and efficacy. A total of 92 [82%] patients who received etrasimod 2 mg in the OLE completed the study. Treatment-emergent adverse events occurred in 60% [67/112] of patients receiving etrasimod 2 mg at any time, most commonly worsening ulcerative colitis and anaemia; 94% of adverse events were mild/moderate. At end of treatment, 64% of patients met the criteria for clinical response, 33% for clinical remission, and 43% for endoscopic improvement. Week 12 clinical response, clinical remission, or endoscopic improvement was maintained to end of treatment in 85%, 60%, or 69% of patients, respectively. Steroid-free clinical remission occurred in 22% of overall patients.ConclusionsIn this long-term extension study, etrasimod 2 mg demonstrated a favourable safety profile. Most patients with clinical response, clinical remission, or endoscopic improvement at Week 12 maintained that status to end of treatment.

Project description:Background and aimsTofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis. Here, we evaluate the efficacy and safety of tofacitinib retreatment following treatment interruption in patients with ulcerative colitis.MethodsHere, patients with clinical response to tofacitinib 10mg b.d. induction therapy were randomised to receive placebo in OCTAVE Sustain. Those experiencing treatment failure after Week 8 of OCTAVE Sustain entered OCTAVE Open and reinitiated tofacitinib 10mg b.d. [retreatment subpopulation]; efficacy and safety data are presented up to Month 36 of OCTAVE Open.ResultsMedian time to treatment failure following interruption was 169 [95% CI, 94.0-179.0] and 123 [95% CI, 91.0-168.0] days for induction remitters and induction responders but nonremitters, respectively. Following retreatment with tofacitinib, rates (non-responder imputation after a patient discontinued; last observation carried forward imputation after a patient advanced to a subsequent study [NRI-LOCF]) of clinical response, remission, and endoscopic improvement were 74.0%, 39.0%, and 55.0% at Month 2, and 48.5%, 37.4%, and 42.4% at Month 36, respectively. Among induction remitters and induction responders but non-remitters, clinical response rates at Month 36 were 60.6% and 42.4% [NRI-LOCF], respectively. Efficacy was recaptured regardless of prior tumour necrosis factor inhibitor failure status. The safety profile of tofacitinib 10mg b.d. retreatment was consistent with the overall cohort and demonstrated no new safety risks associated with exposure ≤36 months.ConclusionsMedian time to treatment failure was numerically higher in induction remitters versus induction responders but non-remitters. Following treatment interruption, efficacy was safely and successfully recaptured with tofacitinib 10mg b.d. retreatment in a substantial proportion of patients.

Project description:BackgroundObesity may affect efficacy and safety of biologic treatments for ulcerative colitis (UC). Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of UC.AimsTo assess efficacy and safety of tofacitinib in patients with UC, by baseline body mass index (BMI).MethodsThis post hoc analysis evaluated patients with UC receiving placebo or tofacitinib from the 8-week OCTAVE Induction 1 and 2 (NCT01465763, NCT01458951) and 52-week OCTAVE Sustain (NCT01458574) studies. Patients were stratified by BMI at OCTAVE Induction 1 and 2 baseline (<25, 25 to <30 and ≥30 kg/m2 ). Outcomes included remission, endoscopic improvement, clinical response, sustained steroid-free remission, Inflammatory Bowel Disease Questionnaire total score and Short Form-36 Health Survey scores. Adverse events were evaluated.ResultsAt Week 8 of OCTAVE Induction 1 and 2, and Week 52 of OCTAVE Sustain, higher proportions of patients receiving tofacitinib 5 or 10 mg twice daily (b.d.) achieved clinical response vs placebo, regardless of baseline BMI subgroup (all P < 0.05). Proportions of patients achieving efficacy endpoints were generally similar across BMI subgroups; in univariate and multivariate regression analyses, BMI was not a significant predictor (all P ≥ 0.05; univariate BMI [continuous] odds ratio for remission: 0.98 [95% confidence interval 0.95, 1.02]). There was no consistent trend between BMI and adverse events. Among patients receiving tofacitinib 10 mg b.d. in OCTAVE Induction 1 and 2, serious infections were numerically greater in the BMI ≥30 subgroup (3.2%) vs other subgroups (0.4%). Limitations included small patient numbers in the BMI ≥30 subgroup.ConclusionsEfficacy and safety of tofacitinib were similar in patients with UC regardless of baseline BMI.

Project description:BackgroundEndoscopy is routine in trials of ulcerative colitis therapies.AimTo investigate agreement between central and local Mayo endoscopic subscore (MES) reads in the OCTAVE programme METHODS: Flexible sigmoidoscopy was performed in tofacitinib induction (OCTAVE Induction 1&2, NCT01465763 and NCT01458951), maintenance (OCTAVE Sustain, NCT01458574) and open-label, long-term extension (OCTAVE Open, NCT01470612) studies. Kappa statistics and Bowker's tests evaluated agreement/disagreement between centrally and locally read MES, with potential determinants of differences analysed by logistic regression.ResultsModerate-to-substantial agreement was observed between central and local reads at screening (77.1% agreement; kappa 0.62 [95% confidence interval 0.59-0.66]), OCTAVE Induction 1&2 week (Wk) 8 (63.8%; 0.62 [0.59-0.66]), OCTAVE Sustain Wk 52 (55.6%; 0.56 [0.50-0.62]) and for induction non-responders at OCTAVE Open month 2 (59.9%; 0.54 [0.48-0.60]). Where disagreements occurred, local reads were systematically lower than central reads at OCTAVE Induction 1&2 Wk 8, OCTAVE Sustain Wk 52 and OCTAVE Open month 2 (Bowker's P < 0.0001); this difference was not observed at screening (P = 0.0852). Using multivariable logistic regression, geographical region, C-reactive protein (Wk 8), partial Mayo score (Wk 8) and prior tumour necrosis factor antagonist failure were associated with disparity at OCTAVE Induction 1&2 Wk 8 (P < 0.05). In OCTAVE Induction 1&2 and OCTAVE Sustain, significantly higher proportions of patients endoscopic improvement, remission and endoscopic remission with tofacitinib vs placebo, using either central or local reads.ConclusionModerate-to-substantial agreement was observed between central and local endoscopic reads. Where disagreements occurred, local reads were systematically lower than central reads at most timepoints, suggesting potential bias.

Project description:Background and aimsThis analysis examined the long-term safety and efficacy of ozanimod in patients with moderately to severely active ulcerative colitis [UC] with ≥ 4 years of follow-up in the phase 2 TOUCHSTONE open-label extension [OLE].MethodsPatients receiving placebo or ozanimod HCl 0.5 mg or 1 mg during the double-blind period could enter the OLE [ozanimod HCl 1 mg daily]. Partial Mayo score [pMS] clinical response and remission were assessed through OLE week 200 and summarized descriptively using observed cases [OC] and non-responder imputation [NRI]. Endoscopy was required at OLE week 56 and the end of treatment. Parameters associated with endoscopy were summarized at weeks 56 and 104 [OC], and week 56 [NRI]. C-reactive protein and faecal calprotectin were assessed. Adverse events were monitored throughout the study.ResultsOf 197 patients receiving double-blind treatment, 170 entered the OLE. Discontinuation rates were 28% at year 1 and 15-18% annually through year 4. Partial Mayo measures indicated clinical response and remission rates at OLE week 200 of 93.3% and 82.7%, respectively, using OC and 41% and 37% with the more conservative NRI analysis. At weeks 56 and 104, respectively, histological remission rates were 46.3% and 38.5%, and endoscopic improvement rates were 46.4% and 46.5% [OC]. No new safety signals were identified during ≥ 4 years of follow-up.ConclusionsThere was a high rate of continued study participation and long-term benefit with ozanimod HCl 1 mg daily based on clinical, histological and biomarker measures in patients with moderately to severely active UC in the TOUCHSTONE OLE.

Project description:The increasing knowledge on ulcerative colitis' pathophysiology has contributed to the expansion of the therapeutic arsenal for this condition. However, to date, 25-40% of patients with ulcerative colitis remain primary or secondary non-responders to therapy, and up to 10% need to eventually undergo a colectomy. Janus kinase inhibitors block cytokine signalling involved in the pathogenesis of several inflammatory conditions. Tofacitinib is the first drug of this class approved for moderate-to-severely active ulcerative colitis in patients for whom disease worsened and those who did not improve with conventional therapy (aminosalicylates, corticosteroids and immunosuppressants) or monoclonal antibodies. We aimed to review the main aspects and concerns related to the current use of tofacitinib and to explore its future application.

Project description:Background and aimsTofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis. We report integrated analyses of infections in the Phase [P]2 and P3 OCTAVE programmes.MethodsThree cohorts were analysed: Induction [P2/3 induction studies]; Maintenance [P3 maintenance study]; and Overall [all tofacitinib-treated patients in induction, maintenance, or ongoing, open-label, long-term extension studies; as of May 2019]. Proportions and incidence rates [IRs; unique patients with events/100 patient-years] of serious infections [SIs], herpes zoster [HZ] [non-serious and serious], and opportunistic infections [OIs] are reported [censored at time of event].ResultsIn the Induction Cohort [N = 1220], no patients receiving placebo and eight [0.9%] receiving tofacitinib 10 mg twice daily [BID] developed SIs. Maintenance Cohort [N = 592] SI IRs (95% confidence interval [CI]) were 1.94 [0.23-7.00] for placebo and 1.35 [0.16-4.87] and 0.64 [0.02-3.54] for tofacitinib 5 and 10 mg BID, respectively; HZ IRs were 0.97 [0.02-5.42], 2.05 [0.42-6.00], and 6.64 [3.19-12.22], respectively. In the Overall Cohort [N = 1157; 82.9% predominantly received tofacitinib 10 mg BID], SI, HZ, and non-HZ OI IRs were 1.70 [1.24-2.27], 3.48 [2.79-4.30], and 0.15 [0.04-0.38], respectively. No SIs resulted in death.ConclusionsDuring induction, SIs were more frequent with tofacitinib versus placebo. SIs were generally infrequent in the Maintenance and Overall Cohorts, with rates comparable between treatment groups. Maintenance Cohort HZ IR was numerically higher with tofacitinib 10 mg BID versus 5 mg BID. Overall Cohort HZ IRs remained stable over time. Non-HZ OIs and viral infections were rare.

Project description: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.

Project description:Background:Tofacitinib is an oral, small molecule Janus kinase inhibitor that is being investigated for ulcerative colitis (UC). Tofacitinib is approved for rheumatoid arthritis and psoriatic arthritis, where it has been shown to increase herpes zoster (HZ) risk. We evaluated HZ risk among UC patients using tofacitinib. Methods:HZ cases were identified in tofacitinib phase II/III/ongoing, open-label, long-term extension (OLE) UC trials. We calculated HZ incidence rates (IRs) per 100 patient-years of tofacitinib exposure within phase III maintenance (Maintenance Cohort) and phase II/III/OLE (Overall Cohort) studies, stratified by baseline demographics and other factors. HZ risk factors were evaluated in the Overall Cohort using Cox proportional hazard models. Results:Overall, 65 (5.6%) patients developed HZ. Eleven patients had multidermatomal involvement (2 nonadjacent or 3-6 adjacent dermatomes), and 1 developed encephalitis (resolved upon standard treatment). Five (7.7%) events led to treatment discontinuation. HZ IR (95% confidence interval [CI]) in the Overall Cohort was 4.07 (3.14-5.19) over a mean (range) of 509.1 (1-1606) days, with no increased risk observed with increasing tofacitinib exposure. IRs (95% CI) were highest in patients age ?65 years, 9.55 (4.77-17.08); Asian patients, 6.49 (3.55-10.89); patients with prior tumor necrosis factor inhibitor (TNFi) failure, 5.38 (3.86-7.29); and patients using tofacitinib 10 mg twice daily, 4.25 (3.18-5.56). Multivariate analysis identified older age and prior TNFi failure as independent risk factors. Conclusions:In tofacitinib-treated UC patients, there was an elevated risk of HZ, although complicated HZ was infrequent. Increased HZ rates occurred in patients who were older, Asian, or had prior TNFi failure (NCT00787202, NCT01465763, NCT01458951, NCT01458574, NCT01470612).
