Tofacitinib is an oral Janus kinase inhibitor for the treatment of ulcerative colitis (UC). Aim:This post hoc analysis evaluated tofacitinib persistence in patients with UC in OCTAVE Open, an open-label, long-term extension study of patients receiving tofacitinib 5 or 10 mg twice daily. Methods: Kaplan-Meier estimates for tofacitinib drug survival and reasons for discontinuations were evaluated. Baseline factors were analysed as predictors of persistence. Results:This analysis included 603 patients: 280 entered OCTAVE Open with a clinical response (164 in remission and 116 not in remission), 220 were delayed responders, 75 were retreatment responders and 35 were dose escalation responders, treated for up to 7 years in OCTAVE Open. Of these, 118 (42.1%) responders, 121 (55.0%) delayed responders, 40 (53.3%) retreatment responders and 17 (48.6%) dose escalation responders discontinued tofacitinib with a median time to discontinuation of 5.6, 4.5, 4.0 and 4.4 years, respectively. The estimated 2- and 5-year drug survival rates in the responders (including patients in remission and not in remission) were 73.9% and 54.5%, respectively. Corresponding persistence values for delayed responders were 69.5% and 45.2%, for retreatment responders, 70.7% and 40.0%, and for dose escalation responders, 74.3% and 32.8%. ConclusionIn: OCTAVE Open, a high proportion of patients maintained tofacitinib treatment, with the median survival by group ranging from 4.0 to 5.6 years although these analyses are post hoc and limited by sample size. Further research should focus on factors to enhance persistence with tofacitinib treatment in patients with UC, This study was sponsored by Pfizer.

Background In patients with ulcerative colitis (UC), risks of infection and malignancies increase with age. Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of UC. This analysis assessed age as a risk factor for adverse events of special interest (AESI) in the tofacitinib UC clinical program. Methods Data were from phase 2 and 3 induction studies, a phase 3 maintenance study, and an open-label, long-term extension study. Efficacy and/or safety outcomes were analyzed in the Induction, Maintenance, and Overall Cohorts (patients who received ≥ 1 dose of tofacitinib), stratified by age. The effects of baseline demographic and disease-related factors on AESI incidence were assessed by Cox proportional-hazards regression analysis. Results In the Overall Cohort (1157 patients with ≤ 6.8 years’ tofacitinib treatment), age was a statistically significant predictor of herpes zoster (HZ), malignancies excluding nonmelanoma skin cancer (NMSC), and NMSC. Other statistically significant predictors included prior tumor necrosis factor inhibitor failure for HZ, NMSC, and opportunistic infection events, and prior duration of UC for malignancies excluding NMSC. In the Induction and Maintenance Cohorts, a higher proportion of tofacitinib-treated than placebo-treated patients (numerical difference) achieved the efficacy endpoints (endoscopic improvement, clinical remission, clinical response) across all age groups. Conclusions Older individuals receiving tofacitinib as induction and maintenance therapy to treat UC may have an increased risk of HZ, malignancies (excluding NMSC), and NMSC versus similarly treated younger patients, consistent with findings from the general population. Across all age groups, tofacitinib demonstrated greater efficacy than placebo as an induction and maintenance therapy.

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis. We evaluate baseline characteristics as predictors of sustained response and remission in patients with ulcerative colitis receiving tofacitinib maintenance therapy. Methods Patients with clinical response following OCTAVE Induction 1 and 2 entered OCTAVE Sustain and were rerandomized to receive tofacitinib 5 or 10 mg twice daily or placebo. Baseline characteristics were stratified by week 52 efficacy endpoints (remission, sustained remission, clinical response, sustained clinical response). Associations between baseline characteristics and efficacy endpoints were evaluated using logistic regression analyses. Results Overall, 170 of 487 (34.9%) patients were in remission at week 52. In multivariable modeling, endoscopic subscore at baseline of OCTAVE Induction 1 and 2 (2 vs 3; odds ratio [OR], 1.60; 95% confidence interval [CI], 1.06-2.44]), partial Mayo score ( Conclusion Patients with greater clinical improvement after 8 weeks of tofacitinib induction therapy are more likely to maintain response or remission with tofacitinib regardless of dose received during maintenance, highlighting the importance of a robust response to induction therapy.

BACKGROUND Tofacitinib 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. AIMS The 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. METHODS Eligible 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). RESULTS In 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. CONCLUSION Tofacitinib demonstrated consistent safety up to 7.0 years. Data collected up to Month 36 support long-term efficacy beyond the 52-week maintenance study.

BACKGROUND Obesity 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. AIMS To assess efficacy and safety of tofacitinib in patients with UC, by baseline body mass index (BMI). METHODS This 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 (

Background and Aims Tofacitinib is an oral small molecule Janus kinase [JAK] inhibitor for the treatment of ulcerative colitis. We report an integrated summary of tofacitinib safety [exposure: ≤7.8 years] from the global clinical programme. Methods Patients receiving tofacitinib 5 or 10 mg twice daily [BID] from completed phase [P]2/3 placebo-controlled studies, an open-label, long-term extension study [final data cut-off: August 24, 2020], and interim analysis of a P3b/4 study (interim data cut-off: February 20, 2020; Overall plus P3b/4 [2020] Cohort) were included. Proportions with adverse events [AEs] and serious AEs, and incidence rates [IRs; unique patients with events/100 patient-years] for deaths and AEs of special interest [AESI] were evaluated. Opportunistic infections, malignancies, major adverse cardiovascular events [MACE] and gastrointestinal perforations were adjudicated. Results In total, 1157 patients received one or more dose of tofacitinib (mean duration: 946.9 days); 955/1157 [83%] received a predominant dose of 10 mg BID; 412/1157 [35.6%] received tofacitinib for >4 years; 992/1157 [85.7%] had AEs, 244/1157 [21.1%] had serious AEs and 134/1157 (11.6%) discontinued use due to AEs. IRs [95% confidence intervals] for all tofacitinib doses were: deaths, 0.23 [0.09–0.46]; serious infections, 1.69 [1.26–2.21]; herpes zoster [non-serious and serious], 3.30 [2.67–4.04]; opportunistic infections, 1.03 [0.70–1.46]; malignancies (excluding non-melanoma skin cancer [NMSC]), 0.84 [0.55–1.24]; NMSC, 0.73 [0.45–1.10]; MACE, 0.29 [0.13–0.55]; deep vein thrombosis, 0.03 [0.00–0.18]; pulmonary embolism, 0.19 [0.07–0.42]; gastrointestinal perforations, 0.10 [0.02–0.28]. Conclusions AESI IRs were stable to 7.8 years and generally JCC Topic/keyword selection: 3. Clinical trials

Background Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). We present integrated analyses of nonmelanoma skin cancer (NMSC) incidence in the tofacitinib UC clinical program. Methods Nonmelanoma skin cancer events were evaluated from 3 randomized, placebo-controlled studies: 2 identical, 8-week induction studies (NCT01465763, NCT01458951), a 52-week maintenance study (NCT01458574), and an open-label, long-term extension study (NCT01470612). Cohorts analyzed were: Induction, Maintenance, and Overall (patients receiving ≥1 dose of tofacitinib 5 mg or 10 mg twice daily [BID]). An independent adjudication committee reviewed potential NMSC. Proportions and incidence rates (IRs; unique patients with events per 100 patient-years of exposure) for NMSC were evaluated. A Cox proportional hazards model was used for risk factor analysis. Results Nonmelanoma skin cancer was evaluated for 1124 patients (2576.4 patient-years of tofacitinib exposure; ≤6.8 years’ treatment). In the Induction Cohort, NMSC IR was 0.00 for placebo and 1.26 for 10 mg BID. Nonmelanoma skin cancer IR was 0.97 for placebo, 0.00 for 5 mg BID and 1.91 for 10 mg BID in the Maintenance Cohort, and 0.73 (n = 19) in the Overall Cohort. No NMSC was metastatic or led to discontinuation. In the Overall Cohort, Cox regression identified prior NMSC (hazard ratio [HR], 9.09; P = 0.0001), tumor necrosis factor inhibitor (TNFi) failure (3.32; P = 0.0363), and age (HR per 10-year increase, 2.03; P = 0.0004) as significant independent NMSC risk factors. Conclusions For patients receiving tofacitinib, NMSC occurred infrequently. Older age, prior NMSC, and TNFi failure, which are previously reported NMSC risk factors in patients with UC, were associated with increased NMSC risk.

Background and Aims Tofacitinib 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. Methods Three 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]. Results In 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. Conclusions During 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.

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). We present an updated analysis of non-melanoma skin cancer (NMSC) events in the tofacitinib UC clinical programme, including final data from the open-label, long-term extension (OLE) study (as of 24 Aug 2020). Methods NMSC events were evaluated from 3 randomised, placebo (PBO)-controlled studies (2 Phase [P]3 induction studies [NCT01465763; NCT01458951]; 1 P3 maintenance study [NCT01458574]) and an OLE study (NCT01470612), as 3 cohorts: Induction (P3 induction studies [patients (pts) receiving tofacitinib 10 mg twice daily (BID) or PBO]); Maintenance (P3 maintenance study [pts receiving tofacitinib 5 or 10 mg BID or PBO]); Overall (pts receiving tofacitinib 5 or 10 mg BID in P3 or OLE studies). Analysis was by predominant dose (PD) 5 or 10 mg BID, based on average daily dose Results 1124 pts were evaluated for NMSC (2809.4 pt-years of tofacitinib exposure; up to 7.8 years of treatment; median duration 685.5 days). NMSC events in Induction and Maintenance were previously reported (Table 1).1 In Overall, NMSC occurred in 21 pts (IR 0.73 [95% confidence interval (CI) 0.45, 1.12]): PD tofacitinib 5 mg BID n=5, IR 0.63 (0.21, 1.48); PD tofacitinib 10 mg BID n=16, IR 0.77 (0.44, 1.25) (Table 1); 2 new cases since May 2019.1 Eleven pts had squamous cell carcinoma and 15 pts had basal cell carcinoma; 5 pts had both. No NMSC was metastatic or led to discontinuation. IRs by time interval and subgroup are reported (Table 2). Prior NMSC (hazard ratio [HR] 12.08 [95% CI 4.20, 34.76]) and age (per 10-year increase, HR 2.01 [1.38, 2.93]) were significant risk factors for NMSC in the multivariable analysis. Prior immunosuppressant use was not a significant risk factor in either the multivariable or univariate analyses. Conclusion In this analysis, NMSC IRs for tofacitinib were similar to those in pts with UC treated with biologics2 and those previously reported in the tofacitinib UC clinical programme.1 NMSC events were more likely to occur in pts with recognised NMSC risk factors: prior NMSC and increasing age.3 Dose dependency of NMSC IR could not be concluded here, as dose changes were permitted. NMSC IRs remained stable over time, up to 7.8 years of exposure. References

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). We present an updated analysis of adjudicated malignancies in the tofacitinib UC clinical programme, including final data from the open-label, long-term extension (OLE) study (as of 24 Aug 2020). Methods Malignancies were evaluated from 3 randomised, placebo-controlled studies (2 Phase [P]3 induction studies [NCT01465763; NCT01458951]; 1 P3 maintenance study [NCT01458574]) and an OLE study (NCT01470612). Three cohorts were analysed: Induction (P3 induction studies), Maintenance (P3 maintenance study) and Overall (patients receiving tofacitinib 5 or 10 mg twice daily [BID] in P3 or OLE studies; data from the previous data cut [May 2019] are also reported for comparison). Analysis was by predominant dose (PD) 5 or 10 mg BID, based on average daily dose Results 1124 patients were evaluated for malignancies (2809.4 patient-years of tofacitinib exposure; up to 7.8 years of treatment; median duration of 685.5 days). No malignancies (excluding NMSC) occurred in Induction Cohort patients. Malignancies (excluding NMSC) occurred in 1 Maintenance Cohort patient (who was receiving placebo) and in 25 Overall Cohort patients (IR 0.86 [95% confidence interval (CI) 0.56, 1.27]: PD tofacitinib 5 mg BID n=5, IR 0.63 [95% CI 0.20, 1.47]; PD tofacitinib 10 mg BID n=20, IR 0.95 [95% CI 0.58, 1.46]); 5 new cases since May 2019 (Table).1 NMSC events in the Induction and Maintenance Cohorts were previously reported (Table).1 NMSC events occurred in 21 Overall Cohort patients (IR 0.73 [95% CI 0.45, 1.12]): PD tofacitinib 5 mg BID n=5, IR 0.63 (95% CI 0.21, 1.48); PD tofacitinib 10 mg BID n=16, IR 0.77 (95% CI 0.44, 1.25); 2 new cases since May 2019 (Table).1 Conclusion There was no apparent clustering of types of malignancy, excluding NMSC. Malignancies (excluding NMSC) and NMSC IRs remained stable over time, being comparable to those previously reported in the tofacitinib UC clinical programme.1 In this analysis, malignancies (excluding NMSC) and NMSC IRs were similar to those in patients with UC treated with tumour necrosis factor inhibitors, as reported from claims data (IRs of 0.63 and 1.69, respectively).2 References

Background and Aims Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis. Here, we evaluate the efficacy and safety of tofacitinib re-treatment following treatment interruption in patients with ulcerative colitis. Methods Here, patients with clinical response to tofacitinib 10 mg 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 re-initiated tofacitinib 10 mg b.d. [re-treatment subpopulation]; efficacy and safety data are presented up to Month 36 of OCTAVE Open. Results Median time to treatment failure following interruption was 169 (95% confidence interval [CI], 94.0–179.0) and 123 [95% CI, 91.0–168.0] days for induction remitters, and induction responders but non-remitters, respectively. Following re-treatment with tofacitinib, rates (non-responder imputation after a patient discontinued; latest 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 10 mg b.d. re-treatment was consistent with the overall cohort and demonstrated no new safety risks associated with exposure of ≤36 months. Conclusions Median 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 10 mg b.d. re-treatment in a substantial proportion of patients [ClinicalTrials.gov:NCT01458574;NCT01470612].

Background: Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). Here, we report steroid-free efficacy and safety with tofacitinib among patients with UC who received corticosteroids at baseline of the maintenance study (OCTAVE Sustain). Methods: This analysis included patients with clinical response following OCTAVE Induction 1 and 2 who were re-randomized to receive placebo, or tofacitinib 5 or 10 mg twice daily (b.d.), in OCTAVE Sustain for 52 weeks and were receiving corticosteroids at OCTAVE Sustain baseline. Corticosteroid tapering was mandatory during OCTAVE Sustain. Rates of steroid-free remission, endoscopic improvement, and clinical response were assessed, stratified by baseline characteristics. Adverse events (AEs) were stratified by treatment and steroid-free remission status. Results: Overall, 289/593 patients had corticosteroid use at OCTAVE Sustain baseline. At week 52, steroid-free remission, endoscopic improvement, and clinical response rates were 10.9%, 11.9%, and 17.8% among patients receiving placebo, 27.7%, 29.7%, and 40.6% among patients receiving tofacitinib 5 mg b.d., and 27.6%, 29.9%, and 43.7% among patients receiving tofacitinib 10 mg b.d., respectively (non-responder imputation; all p Conclusion: For patients with baseline corticosteroid use in OCTAVE Sustain, the odds of achieving steroid-free efficacy endpoints were significantly higher for tofacitinib versus placebo, irrespective of tofacitinib dose. There were no apparent differences in AEs of special interest by steroid-free remission status. ClinicalTrials.gov: NCT01458574

Background and Aims Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis. We present primary completion analysis from RIVETING, an ongoing, double-blind, randomised, parallel-group trial evaluating efficacy and safety of tofacitinib dose reduction to 5 mg twice daily [BID] versus remaining on 10 mg BID in patients in stable remission on tofacitinib 10 mg BID maintenance therapy. Methods Patients had received tofacitinib 10 mg BID for ≥ 2 consecutive years and been in stable remission for ≥ 6 months before enrolment. The primary endpoint was modified Mayo score remission at Month 6. Safety was assessed up to February 20, 2020 [data cut-off]. Results In all, 140 patients were randomised [1:1] to tofacitinib 5 or 10 mg BID; 77.1% and 90.0% of patients in the 5 and 10 mg BID groups, respectively, were in modified Mayo score remission at Month 6 (adjusted difference 12.9%; 95% confidence interval [CI] 0.5–25.0). Smaller differences between treatment groups were seen in patients with baseline endoscopic subscore of 0 versus 1 [9.8%; –3.0–22.6, and 21.1%; –6.1–48.2, respectively], and in patients without versus with prior tumour necrosis factor inhibitor [TNFi] failure [9.5%; –6.6–25.6, and 17.4%; –1.6–36.3, respectively]. Adverse events [AE] and serious AE rates were similar across treatment groups; no deaths were reported. Conclusions Most patients in stable remission on 10 mg BID maintenance therapy maintained remission following dose de-escalation. For patients who dose de-escalated, those in deep endoscopic remission and those without prior TNFi failure were more likely to maintain remission. Efficacy data were limited to the first 6 months; a longer duration of follow-up during RIVETING will further characterise the impact of dose reduction on maintenance of remission. Safety findings were consistent with the established safety profile of tofacitinib., Graphical Abstract Graphical Abstract

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of UC. In data analysed from a large, ongoing (data cut-off February 2019 [a]; database unlocked; data may be subject to change), post-authorisation safety study in patients with RA (≥50 years; ≥1 cardiovascular risk factor; enrolled on a stable dose of MTX), the incidence rate (IRs; unique patients with events per 100 pt-years [PY]) of pulmonary embolism (PE) in patients treated with tofacitinib 10mg BID (0.54 [95% CI] 0.32, 0.87]) was numerically higher compared with 5 mg BID (0.27 [0.12, 0.52]) and statistically different from TNFi (0.09 [0.02, 0.26]). Corresponding IRs for deep vein thrombosis (DVT) were 0.38 (0.20, 0.67), 0.30 (0.14, 0.55) and 0.18 (0.07, 0.39).1 UC is a known risk factor for DVT and PE. Subsequently, updates to the tofacitinib prescribing information have been made, with venous thromboembolism added as a warning and adverse drug reaction. Here, we provide an update on the incidence of DVT and PE in the tofacitinib UC clinical development programme, as of May 2019.2 Methods DVT and PE events were evaluated from 4 randomised placebo-controlled studies (Phase [P]2/P3 induction studies and P3 maintenance study) and an ongoing, open-label, long-term extension (OLE) study.3,4 Three cohorts were analysed: Induction, Maintenance and Overall (patients receiving tofacitinib 5 or 10mg BID in P2/P3/OLE studies; patients were categorised based on the average daily dose: predominant dose [PD] 5 or 10 mg BID). Results 1157 patients were evaluated for DVT and PE, with 2581 PY of tofacitinib exposure and up to 6.8 years’ treatment. In the Induction and Maintenance Cohorts, 2 patients had DVT and 2 had PE; all were receiving placebo at the time of the event (tables). In the Overall Cohort, DVT occurred in 1 pt and PE in 4 patients during the OLE study, after ≥7 months of treatment; all patients had received PD 10 mg BID (83% of Overall Cohort received PD 10 mg BID) and had other (non-UC) risk factors for venous thrombosis (tables). Conclusion IRs in the Overall Cohort have remained stable since the previously reported data cut.2 All of the events in tofacitinib patients (PD 10 mg BID) occurred during the OLE study and all had other (non-UC) risk factors for thromboembolic events. This analysis is limited by sample size and duration of drug exposure; further study is needed. [a] The tofacitinib 10mg BID arm of the study was discontinued in February 2019 and patients who re-consented and chose to remain in the study were switched to the 5 mg BID arm. References

Tofacitinib is an oral, small molecule inhibitor of JAK for the treatment of ulcerative colitis (UC). We evaluated the onset of symptom improvement in post-hoc analyses of data from 2 phase 3 trials of induction therapy with tofacitinib in patients with UC (OCTAVE Induction 1 and 2).The studies comprised patients with moderate to severe active UC who were intolerant to, or failed by previous treatment with, corticosteroids, thiopurines, and/or tumor necrosis factor (TNF) antagonists. Patients received tofacitinib (10 mg twice daily, n = 905) or placebo (n = 234) for 8 weeks. Daily Mayo stool frequency and rectal bleeding subscores were calculated using diary data from the first 15 days of therapy. We analyzed data from subgroups including failure of prior anti-TNF therapy, baseline corticosteroid use, and baseline serum levels of C-reactive protein.Mean changes were significantly greater in patients given tofacitinib vs placebo in reductions from baseline stool frequency subscore (tofacitinib: -0.27 vs placebo: -0.11; P.01), total number of daily bowel movements (-1.06 vs -0.27; P.0001), and rectal bleeding subscore (-0.30 vs -0.14; P.01) by day 3. Compared with placebo, more tofacitinib-treated patients had reductions from baseline in stool frequency subscore (by ≥1 point for tofacitinib, 241/837, 28.8% vs placebo, 39/218, 17.9%) (P.01) and rectal bleeding subscore (by ≥1 point for tofacitinib, 266/830, 32.0% vs placebo, 43/214, 20.1%) (P.01) by day 3. A consistent effect of tofacitinib was observed in all subgroups.In a post-hoc analysis of data from phase 3 trials of induction therapy with tofacitinib in patients with UC, we found significant improvements in symptoms among patients given tofacitinib compared with placebo within 3 days. These findings indicate the rapid onset of effect of this drug in patients with UC. ClinicalTrials.gov no: NCT01465763 and NCT01458951.

Background Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). We aimed to estimate the overall incidence of safety events in patients with UC in a real-life population cohort for comparison with the tofacitinib UC clinical trial program. Methods Clinical trial-like criteria were applied to an IBM MarketScan® claims database population-based cohort (n = 22,967) of patients with UC (October 2010 to September 2015) to identify a UC trial-like cohort treated with tumor necrosis factor inhibitors (TNFi; n = 6366) to compare with the tofacitinib UC clinical trial cohort (n = 1157). Results Incidence rates (events per 100 patient-years; [95% confidence interval]) in the UC trial-like cohort were as follows: serious infections, 3.33 (2.73–4.02); opportunistic infections (OIs; excluding herpes zoster [HZ]), 1.45 (1.06–1.93); HZ, 1.77 (1.34–2.29); malignancies (excluding nonmelanoma skin cancer [NMSC]), 0.63 (0.43–0.90); NMSC, 1.69 (1.35–2.10); major adverse cardiovascular events (MACE), 0.51 (0.31–0.79); pulmonary embolism (PE), 0.54 (0.30–0.89); deep vein thrombosis (DVT), 1.41 (1.00–1.93); and gastrointestinal perforations, 0.31 (0.16–0.54). Compared with the UC trial-like cohort, tofacitinib-treated patients had numerically lower incidence rates for serious infections (1.75 [1.27–2.36]), OIs (excluding HZ; 0.16 [0.04–0.42]), NMSC (0.78 [0.47–1.22]), PE (0.16 [0.04–0.41]), and DVT (0.04 [0.00–0.23]), and a higher rate for HZ (3.57 [2.84–4.43]); rates for malignancies (excluding NMSC), MACE, and gastrointestinal perforations were similar. Conclusions When acknowledging limitations of comparing claims data with controlled clinical trial data, incidence rates for HZ among TNFi-treated patients in the UC trial-like cohort were lower than in the tofacitinib UC clinical trial cohort; rates for serious infections, OIs, NMSC, PE, and DVT were numerically higher.

Background & Aims Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). The efficacy and safety of tofacitinib in patients with moderate to severe UC, up to 1 year, have been reported. We investigated maintenance of efficacy in patients in remission after 52 weeks of maintenance treatment in the pivotal phase 3 study (OCTAVE Sustain); these patients received open-label, long-term treatment with tofacitinib 5 mg twice daily. Methods Patients with moderate to severe UC who completed a 52-week, phase 3 maintenance study (OCTAVE Sustain) were eligible to enroll into the ongoing, phase 3, multicenter, open-label, long-term extension (OCTAVE Open). We analyzed data from 142 patients who were in remission following tofacitinib treatment in OCTAVE Sustain who received tofacitinib 5 mg twice daily during OCTAVE Open. We assessed efficacy (including remission [based on total Mayo score], endoscopic improvement, clinical response, and partial Mayo score up to month 36 of OCTAVE Open) and safety data. Results After 12 months of tofacitinib 5 mg twice daily in OCTAVE Open, 68.3% of patients were in remission, 73.9% had endoscopic improvement, and 77.5% had a clinical response. At month 36, 50.4%, of the patients were in remission, 55.3% had endoscopic improvement, and 56.0% had a clinical response. The safety profile of tofacitinib 5 mg twice daily revealed no new safety risks associated with long-term exposure up to 36 months. Conclusions Efficacy endpoints were maintained for up to 36 months, regardless of prior tofacitinib dose, including patients who reduced from tofacitinib 10 mg to 5 mg twice daily upon OCTAVE Open entry. No new safety risks were identified. ClinicalTrials.gov: OCTAVE Sustain (NCT01458574); OCTAVE Open (NCT01470612).

Background Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). Here, we performed an integrated analysis of malignancy events from the tofacitinib phase 3 UC clinical development program (excluding nonmelanoma skin cancer [NMSC]). Methods Data (up to May 2019) were pooled from two phase 3 induction studies, a phase 3 maintenance study, and an ongoing, open-label, long-term extension (OLE) study, and analyzed as 3 cohorts: induction (N = 1139), maintenance (N = 592), and overall (induction, maintenance, and ongoing OLE study; N = 1124). Proportions and incidence rates (IRs; unique patients with events per 100 patient-years [PY] of exposure) for malignancies confirmed by adjudication were calculated. Results The overall cohort consisted of patients who received at least 1 dose of tofacitinib at 5 or 10 mg twice daily, for up to 6.8 years, with an exposure of 2576.4 PY. Of the 1124 overall cohort tofacitinib-treated patients, 20 developed a malignancy (excluding NMSC; IR, 0.75; 95% confidence interval, 0.46–1.16), of which 17 occurred in patients treated with tofacitinib 10 mg twice daily; importantly, more than 80% of patients predominantly received this dose. Furthermore, there was no apparent clustering of malignancy types, and IRs were stable over time. Conclusions In the tofacitinib UC clinical development program, malignancy events were infrequent, and rates were comparable with those in the tofacitinib rheumatoid arthritis and psoriatic arthritis clinical development programs, and for biologic UC treatments.

Background For patients with UC, flexible maintenance dosing therapy may confer advantages for safety, efficacy, costs and patient preference. Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of UC. Aim To assess the efficacy and safety of tofacitinib dose de-escalation and escalation in patients with UC. Methods We evaluated data (November 2017 data cut-off) from OCTAVE Open, an ongoing, open-label, long-term extension study. The dose de-escalation group comprised 66 tofacitinib induction responders in remission following 52 weeks' tofacitinib 10 mg b.d. maintenance therapy, subsequently de-escalated to 5 mg b.d. in OCTAVE Open. The dose escalation group comprised 57 tofacitinib induction responders who experienced treatment failure while receiving 5 mg b.d. maintenance therapy, subsequently escalated to 10 mg b.d. in OCTAVE Open. Results After tofacitinib de-escalation, 92.4% (61/66) and 84.1% (53/63) of patients maintained clinical response and 80.3% (53/66) and 74.6% (47/63) maintained remission, at months 2 and 12, respectively. After dose escalation, 57.9% (33/57) and 64.9% (37/57) of patients recaptured clinical response and 35.1% (20/57) and 49.1% (28/57) were in remission, at months 2 and 12, respectively. The incidence rate of herpes zoster with dose escalation (7.6 patients with events/100 patient-years) was numerically higher than in the overall tofacitinib UC programme. Conclusions Following tofacitinib de-escalation in patients already in remission on 10 mg b.d., most maintained remission, although 25.4% lost remission, at month 12. For induction responders who dose-escalated following treatment failure on 5 mg b.d. maintenance therapy, 49.1% achieved remission by month 12. (ClinicalTrials.gov number: NCT01470612).

Background Active inflammatory bowel disease increases the risk of adverse pregnancy outcomes. Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). As a small molecule, tofacitinib is likely to cross the placental barrier; however, information on the effects of tofacitinib on pregnancy outcomes is limited. We report pregnancy and newborn outcomes among patients in UC clinical studies with prenatal (maternal/paternal) exposure to tofacitinib. Methods Pregnancies with maternal/paternal exposure to tofacitinib were identified and outcomes reported in 5 tofacitinib UC interventional studies (up to March 2017). Outcomes from tofacitinib rheumatoid arthritis (RA), psoriasis, and psoriatic arthritis interventional studies, and RA noninterventional postapproval safety studies, spontaneous adverse event reporting, and registry data are also reported. Results Of 1157 patients enrolled in the UC interventional studies, 301 were women of childbearing age. Eleven cases of maternal exposure and 14 cases of paternal exposure to tofacitinib (doses of 5 mg or 10 mg twice daily) before/at the time of conception or during pregnancy were identified. Outcomes included 15 healthy newborns, no fetal deaths, no neonatal deaths, no congenital malformations, 2 spontaneous abortions, and 2 medical terminations. Outcomes across other tofacitinib studies and postmarketing cases were consistent, with a healthy newborn being the most common outcome and no fetal deaths. Conclusions Based on the limited data available, pregnancy and newborn outcomes among patients with prenatal (maternal/paternal) exposure to tofacitinib in UC studies appear similar to those reported for other tofacitinib clinical study populations and the general population.

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). RIVETING (NCT03281304) is an ongoing, double-blind, randomised, parallel-group study designed to evaluate the efficacy and safety of dose reduction to tofacitinib 5 mg twice daily (BID) vs remaining on 10 mg BID in patients (pts) with UC in stable remission on tofacitinib 10 mg BID maintenance therapy. Eligible pts had received tofacitinib 10 mg BID for ≥2 consecutive years in an open-label, long-term extension (OLE) study (NCT01470612), and had been in stable remission for ≥6 months (M) and corticosteroid (CS)-free for ≥4 weeks prior to enrolment.1 We aimed to evaluate tofacitinib efficacy outcomes by the number of prior tumour necrosis factor inhibitors (TNFi) failed and by prior CS use. Methods We evaluated the efficacy of tofacitinib 5 mg BID at Month 6 of RIVETING, based on the number of prior TNFi failed (0, 1 or >1), CS use (yes/no) and CS dose ( Results Of the 70 pts randomised to dose-reduce to tofacitinib 5 mg BID, 43 pts had no prior TNFi failure, 17 pts had previous failure with 1 TNFi and 10 pts had previous failure with >1 TNFi. At Month 6, modified Mayo (mMayo) score remission was maintained in 79.1%, 70.6% and 80.0% of pts who had previous failure with 0, 1 and >1 TNFi, respectively. At Month 6, the change from RIVETING BL total Mayo score, mMayo score, partial Mayo score (PMS) and modified PMS was similar across TNFi subgroups (Table 1). Of pts who enrolled into RIVETING, 26 pts were receiving CS (9 received Conclusion In pts who were in stable remission for >6M, efficacy endpoints were maintained following dose reduction to tofacitinib 5 mg BID, regardless of the number of prior TNFi failures or prior CS use. These analyses are post hoc and limited by the small sample size. Reference

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). RIVETING (NCT03281304) is an ongoing, double-blind, randomised, parallel-group study designed to evaluate the efficacy and safety of dose reduction to tofacitinib 5 mg twice daily (BID) vs remaining on 10 mg BID in patients (pts) with UC in stable remission on tofacitinib 10 mg BID maintenance therapy. Eligible pts had received tofacitinib 10 mg BID for ≥2 consecutive years in an open-label, long-term extension study (NCT01470612), and had been in stable remission for ≥6 months and corticosteroid-free for ≥4 weeks prior to enrolment.1 We aimed to determine if faecal calprotectin (FCP), C-reactive protein (CRP) or partial Mayo score (PMS) can be used as predictors of maintaining remission after dose reduction. Methods Median FCP levels, median CRP levels and mean PMS at baseline (BL), Month 1 and Month 3 were analysed by efficacy endpoint status at Month 6 in pts who dose-reduced to tofacitinib 5 mg BID. The proportions of pts who achieved efficacy endpoints at Month 6 were analysed by stool frequency (SF) subscore, rectal bleeding (RB) subscore and modified PMS. Results Seventy pts were randomised to receive tofacitinib 5 mg BID in RIVETING. For pts in modified Mayo score remission at Month 6, PMS was relatively stable over time, whereas PMS increased from BL to Month 1 and Month 3 in pts not in modified Mayo score remission at Month 6; mean change from BL at Month 3 was 0.1 vs 0.7, respectively (Table 1). This trend was also observed for other efficacy endpoints (Table 1). Median FCP levels did not change from BL to Month 3 in pts who achieved Month 6 efficacy endpoints, whereas median FCP levels increased from BL to Month 3 in pts who did not achieve Month 6 efficacy endpoints (except remission) (Table 1). For all efficacy endpoints, no trend was observed in median CRP levels over time in pts who did and did not achieve Month 6 efficacy endpoints (Table 1). A numerically higher proportion of pts with a SF subscore, RB subscore or modified PMS of 0 at Month 1 or Month 3 achieved efficacy endpoints at Month 6 compared with pts with respective subscores >0 (Table 2). Conclusion These analyses suggest that in pts previously in stable remission, an increase in FCP levels at Month 3, or PMS as early as Month 1, may help predict loss of efficacy after dose-reduction from tofacitinib 10 mg BID to 5 mg BID. A SF subscore, RB subscore or modified PMS of 0 at either Month 1 or Month 3 could indicate the likelihood of maintaining efficacy with tofacitinib 5 mg BID at Month 6. These analyses are post hoc, exploratory and limited by the small sample size. Reference

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC).

Eligible pts had received tofacitinib 10 mg BID for ≥2 consecutive years in an open-label, long-term extension study (NCT01470612), and had been in stable remission for ≥6 months (M) and corticosteroid-free for ≥4 weeks prior to enrolment.1 We aimed to evaluate the association between the duration of remission prior to enrolment into RIVETING and the efficacy of tofacitinib 5 and 10 mg BID. Methods Pts who were in partial Mayo score (PMS) remission (a PMS of ≤2 with no individual subscore >1, and a rectal bleeding subscore of 0) at RIVETING baseline were included in this analysis. Pts were randomised to dose-reduce to tofacitinib 5 mg BID or remain on 10 mg BID. We evaluated efficacy endpoints at Month 6 in RIVETING, stratified by duration of PMS remission (0–12, 12–24, 24–36, 36–48, >48 M) at RIVETING baseline. Results At RIVETING baseline, 139 of 140 pts were in PMS remission: 69 pts dose-reduced to tofacitinib 5 mg BID and 70 pts remained on tofacitinib 10 mg BID. In both treatment groups, compared with pts with 24M; these pts also generally had a numerically lower change from baseline modified Mayo and total Mayo scores at Month 6 (Table). At Month 6, following dose reduction to tofacitinib 5 mg BID, PMS remission was maintained in 66.7%, 60.0%, 82.4%, 75.0% and 90.0% of pts with baseline PMS remission durations of 0–12M, 12–24M, 24–36M, 36–48M and >48M, respectively. Corresponding values for pts who continued to receive tofacitinib 10 mg BID were 80.0%, 88.9%, 91.7%, 100.0% and 100.0%. At Month 6, the proportion of pts achieving modified Mayo remission, remission and modified PMS remission was generally higher in pts with baseline PMS remission of >24M vs pts with PMS remission of Conclusion Following dose reduction from tofacitinib 10 to 5 mg BID, rates of modified Mayo remission, remission and PMS remission were numerically higher in pts with a PMS remission duration of >24M vs pts with Reference

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Efficacy and safety of tofacitinib in patients (pts) with UC were evaluated in two 8-week, Phase 3 induction studies (OCTAVE Induction 1&2), a 52-week, Phase 3 maintenance study (OCTAVE Sustain), and an open-label, long-term extension study. Here, we evaluate tofacitinib efficacy in OCTAVE Sustain (NCT01458574) by baseline Mayo endoscopic subscore (ES). Methods Pts with an OCTAVE Sustain baseline ES of 0 or 1 were included. Proportion of pts achieving efficacy endpoints at Week 52 of OCTAVE Sustain (responders from OCTAVE Induction 1&2; tofacitinib 5 or 10 mg twice daily [BID] or placebo [PBO]) was evaluated in relation to OCTAVE Sustain baseline ES. Using logistic regression, the difference in treatment effect (tofacitinib vs PBO) between baseline ES (0 vs 1) for each efficacy endpoint was assessed. Cox proportional hazards regression was used to model the difference in treatment effect between baseline ES (0 vs 1) for time to treatment failure and loss of response. Results At Week 52 of OCTAVE Sustain, a numerically higher proportion of pts with a baseline ES of 0 achieved remission and endoscopic improvement vs pts with a baseline ES of 1, regardless of tofacitinib dose (Table). Logistic regression analyses showed a larger treatment effect of tofacitinib 5 mg BID at Week 52 in pts with a baseline ES of 0 vs 1 (p=0.0306) for clinical response (Table). Treatment effect of tofacitinib 10 mg BID was not significantly different between baseline ES 0 vs 1 for any endpoint (Table). In tofacitinib 5 mg BID-treated pts, Cox proportional hazards regression showed difference in risk vs PBO to be larger in pts with a baseline ES of 0 vs 1 for treatment failure (p=0.0231) and loss of response (p=0.0209); corresponding differences for 10 mg BID-treated pts were not significant (p=0.9239 and p=0.9613, respectively). Conclusion In general, at Week 52 of OCTAVE Sustain, a higher proportion of tofacitinib-treated pts achieved endpoints with a baseline ES of 0 vs 1. Based on proportions, the treatment effect of tofacitinib 5 mg BID was more evident in pts with a baseline ES of 0 vs 1. This difference in treatment effect related to baseline ES was not observed with tofacitinib 10 mg BID. Baseline ES may be an important factor in predicting outcomes, and suggests that aiming for a deeper remission after induction may allow successful maintenance with tofacitinib 5 mg BID. These analyses were post hoc and limited by the small sample sizes.

Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis. Here, we report corticosteroid-free efficacy and safety among patients (pts) who received oral corticosteroids at baseline of the maintenance study (OCTAVE Sustain). Methods Pts with clinical response following OCTAVE Induction 1&2 who were re-randomised to receive placebo or tofacitinib 5 or 10 mg twice daily (BID) in OCTAVE Sustain, and who were receiving oral corticosteroids at baseline of OCTAVE Sustain, were included. Corticosteroid tapering was mandatory at the beginning of OCTAVE Sustain. Steroid-free (not requiring any treatment with corticosteroids for ≥4 weeks prior to the visit) rates of remission, endoscopic improvement and clinical response were assessed at Week 24 and/or Week 52. The association between baseline characteristics and steroid-free efficacy outcomes was evaluated using logistic regression. Safety outcomes were stratified by tofacitinib dose and steroid-free remission status. Results Of 593 pts entering OCTAVE Sustain, 289 had oral corticosteroid use at baseline. Of these, 101 (34.9%) received placebo and 188 received tofacitinib (101 [34.9%] 5 mg BID; 87 [30.1%] 10 mg BID) in OCTAVE Sustain. Among pts receiving oral corticosteroids on Day 1 of OCTAVE Sustain, the mean dose (mg/day [standard deviation], prednisone equivalent) received was 15.8 (6.2), 14.9 (6.2) and 14.4 (6.0) in the placebo, tofacitinib 5 mg BID and tofacitinib 10 mg BID groups, respectively. At Week 24 or Week 52 of OCTAVE Sustain, there was a significant treatment effect for tofacitinib 5 or 10 mg BID vs placebo for steroid-free efficacy endpoints (Table 1). Prior immunosuppressant failure was associated with lower odds of achieving steroid-free remission at Week 52 of OCTAVE Sustain (odds ratio [OR] 0.47 [95% confidence interval (CI) 0.23, 0.95]), while prior tumour necrosis factor inhibitor (TNFi) failure status only had a limited effect, which was not statistically significant (OR 0.53 [95% CI 0.27, 1.02]). Oral corticosteroid dose received at baseline of OCTAVE Sustain did not affect the likelihood of achieving steroid-free remission at Week 52. Adverse events of special interest were infrequent (Table 2). Discontinuations were numerically higher among pts without steroid-free remission (Table 2). Conclusion For pts with baseline oral corticosteroid use in OCTAVE Sustain, the odds of achieving steroid-free efficacy endpoints were significantly higher for tofacitinib 5 or 10 mg BID compared with placebo. Prior TNFi failure was not associated with lower odds of achieving steroid-free remission at Week 52. There were no apparent differences in safety by steroid-free remission status. Data interpretation is limited by small pt numbers.

Introduction: Drug survival in open-label, long-term extension (OLE) studies may provide information on the long-term efficacy and tolerability of a therapy. Methods: We present data on the persistence of tofacitinib treatment in the OLE study for: (1) delayed responders: induction non-responders (pts who did not achieve a clinical response [CR] after 8 weeks [wks] induction treatment with tofacitinib 10 mg BID) who achieved a CR at Wk 8 (total of 16 wks induction) of the OLE study and continued to receive 10 mg BID;(2) retreatment responders: tofacitinib 10 mg BID induction responders who experienced treatment failure with PBO in OCTAVE Sustain and entered the OLE study and received 10 mg BID, and achieved a CR at Wk 8 of the OLE study;and (3) dose escalation responders: tofacitinib 10 mg BID induction responders who experienced treatment failure with 5 mg BID in OCTAVE Sustain and entered the OLE study and received 10 mg BID, and achieved a CR at Wk 8 of the OLE study (Figure 1). The calculations are based on non-responder imputation incorporating multiple imputation to handle missing data due to COVID-19 or non-responder imputation only if there are no missing data due to COVID-19. 3CDAI 50% from baseline (or for subjects with isolated ileal disease and a baseline SES-CD of 4, at least a 2-point reduction from baseline), as scored by central readers.

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.

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). In patients with UC, associations between endoscopic findings and patient-reported outcomes, such as stool frequency (SF) and rectal bleeding (RB), are not well described. Here, we evaluated the diagnostic accuracy of Mayo SF and RB subscores to predict mucosal healing (MH) in OCTAVE Induction 1 and 2 (NCT01465763; NCT01458951). Methods This post hoc analysis used data from OCTAVE Induction 1 and 2, two identical, randomised, placebo-controlled, 8-week, Phase 3 studies of tofacitinib for the treatment of patients with moderately to severely active UC.1 SF (Mayo subscore 0–3), RB (Mayo subscore 0–3) and endoscopic findings (Mayo endoscopic subscore [ES] 0–3) were assessed at baseline and at Week 8. MH and endoscopic normalisation were defined as an ES of 0 or 1, or an ES of 0, respectively. Based on two-by-two contingency tables, diagnostic test characteristics for SF and RB were evaluated: positive and negative predictive values, sensitivity and specificity. Kappa statistics (chance-corrected measure of agreement) and Pearson correlations (a measure of association) were also calculated. All available data at Week 8 were used. Results A total of 614 and 547 patients received treatment (tofacitinib 15 or 10 mg BID, or placebo) in OCTAVE Induction 1 and 2, respectively. Two-by-two contingency table analyses showed that dichotomised SF (0 vs. ≥1) and RB (0 vs. ≥1) were each or both not good predictors of MH (ES of 0 or 1 vs. ≥2) or endoscopic normalisation (ES 0 vs. ≥1), as ≥1 of the four diagnostic test characteristics was Conclusion In patients with UC treated with tofacitinib or placebo in OCTAVE Induction 1 and 2, SF and RB subscores had slight-to-moderate agreement with ES, but were not predictive of MH or endoscopic normalisation. The presence of blood at Week 8 strongly indicated that patients had endoscopic activity, but the absence of blood was associated with MH in Reference

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). The efficacy and safety of tofacitinib were demonstrated in patients with moderate to severe UC in three Phase 3 studies.1 Here, we investigated outcomes in a subpopulation of the ongoing, open-label, long-term extension study (OLE) (OCTAVE Open; NCT01470612; May 2019; database not locked), including maintenance of remission patients receiving tofacitinib 5 mg twice daily (BID) who were dose-escalated to 10 mg BID due to flare. Methods Analysis included the maintenance remission–dose-escalation subpopulation: patients who achieved remission at Week 52 in OCTAVE Sustain (tofacitinib 5 or 10 mg BID, or placebo), entered OLE (5 mg BID), but were dose-escalated to 10 mg BID due to flare (based on total Mayo score [MS]; local read endoscopy). Remission: total MS ≤2 with no subscore >1, and rectal bleeding (RB) subscore 0. Dose escalation during OLE was permitted if patients experienced a flare, defined as ≥3 increase from maintenance study baseline total MS and ≥1 increase in RB and endoscopic subscore (ES; unless ES=3 at baseline and remained 3) after ≥8 weeks of treatment in OLE. Kaplan–Meier for estimation of time to dose escalation was assessed in all OLE maintenance remission population relative to OLE baseline. Partial MS remission (≤2 with no subscore >1; no ES) assessed at Months (M)3, 6, 9 and 12 post-dose-escalation; mucosal healing (MH; ES ≤1) and remission assessed at M12 post-dose-escalation. Adverse events (AEs) also assessed. Results Of the 944 patients enrolled in OLE, 162 were in remission at baseline and received tofacitinib 5 mg BID, and 41 were dose-escalated to 10 mg BID due to flare (22 had prior TNFi failure). The cumulative proportion of patients with dose escalation was 4.3%, 10.6%, 12.6% and 13.2% at M3, 6, 9 and 12 of OLE, respectively. Partial MS remission was 75.0% at M3, and partial MS remission, MH and remission were 95.0%, 63.6% and 57.6%, respectively, at M12 post-dose escalation (Table). One case each of serious infection, herpes zoster (non-serious; opportunistic infection) and malignancy were reported (see Table). Conclusion For patients with moderate to severe UC who entered OLE in remission, received tofacitinib 5 mg BID but flared and were dose-escalated to 10 mg BID, response was recaptured for most by M3 post-dose-escalation and remission was recaptured in the majority by M12. Safety in this subpopulation was generally consistent with that observed in the overall tofacitinib UC programme.2 Due to the small sample size and open-label nature, results should be interpreted with caution.

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Efficacy and safety were demonstrated in 3 Phase 3, randomised, placebo-controlled studies in patients with moderate to severe UC.1 An ongoing, Phase 3, open-label, long-term extension (OLE) study (OCTAVE Open, NCT01470612) included patients from OCTAVE Induction 1 and 2 and OCTAVE Sustain. Methods We present data (as of May 2019) from the ‘maintenance remission’ subpopulation in the OLE study who were in remission (total Mayo score ≤2, no individual subscore >1, rectal bleeding subscore of 0) at Week 52 of OCTAVE Sustain (having received tofacitinib 5 or 10 mg twice daily [BID]). These patients received tofacitinib 5 mg BID as per protocol in the OLE study. Efficacy data up to Month 36 of the OLE study (as observed and with non-responder and last observation carried forward imputation [NRI-LOCF]) are presented for this subpopulation. Safety data are reported for all patients who received tofacitinib 5 mg BID in the OLE study. Results Of 944 patients receiving ≥1 dose of tofacitinib in the OLE study, 163 were in remission at Week 52 of OCTAVE Sustain (mean age 45 years; 46.0% female). Of these, 66 (40.5%) and 76 (46.6%) received tofacitinib 5 and 10 mg BID, respectively, in OCTAVE Sustain, and 21 (12.9%) received a placebo. In total, 67/163 (41.1%) patients discontinued the OLE study, 16 (9.8%) due to adverse events (AEs) excl. worsening UC and 15 (9.2%) due to insufficient clinical response. Among patients that continued, efficacy (Table) was maintained over 36 months and was similar irrespective of the dose received in OCTAVE Sustain. Of 175 patients who received tofacitinib 5 mg BID (incl. 163 from the maintenance remission subpopulation), 152 (86.9%), 33 (18.9%) and 20 (11.4%) had AEs, serious AEs and severe AEs, respectively. The most frequent treatment-emergent AEs (TEAEs) were worsening UC (41 patients, 23.4%) and nasopharyngitis (38 patients, 21.7%). Six (3.4%) patients receiving tofacitinib 5 mg BID had serious infections, 11 (6.3%) had herpes zoster (non-serious and serious), 4 (2.3%) had opportunistic infections, 2 (1.1%) had major adverse cardiovascular events and 5 (2.9%) had malignancy (excl. non-melanoma skin cancer). No deep vein thrombosis, pulmonary embolism or deaths were reported in patients receiving tofacitinib 5 mg BID. Conclusion Most patients in remission at Week 52 of OCTAVE Sustain maintained efficacy with tofacitinib 5 mg BID over 36 months in the OLE study. Similar efficacy was observed for patients whose dose was reduced from tofacitinib 10 mg BID in OCTAVE Sustain to 5 mg BID in the OLE study, vs. those who received 5 mg BID throughout both OCTAVE Sustain and the OLE study. No new safety risks were identified. Reference

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). The efficacy and safety of tofacitinib have been demonstrated in patients with moderate to severe UC in three Phase 3 studies (OCTAVE Induction 1 and 2 [NCT01465763; NCT01458951]; OCTAVE Sustain [NCT01458574]) [1]. Here, we present updated efficacy and safety data of tofacitinib dose escalation in patients with UC participating in an ongoing, open-label, long-term extension (OLE) study (OCTAVE Open, NCT01470612) [2]. Methods We present updated data from the dose-escalation subpopulation of the OLE study (as of May 2019; database not locked) comprising patients who achieved clinical response (CR) following 8 weeks of tofacitinib 10 mg twice daily (BID) induction therapy, entered OCTAVE Sustain receiving tofacitinib 5 mg BID, experienced treatment failure between Week 8 and Week 52, and subsequently entered OCTAVE Open with escalation to tofacitinib 10 mg BID. Treatment failure was defined as an increase of ≥3 points from maintenance study baseline total Mayo score, plus an increase of ≥1 point in both rectal bleeding subscore and centrally read endoscopic subscore (ES), and an absolute ES of ≥2 after ≥8 weeks of maintenance therapy. CR, mucosal healing (MH) and remission (R) were evaluated at Months 2, 12, 24 and 36 of OCTAVE Open (non-responder imputation and last observation carried forward [NRI-LOCF] and observed data). Safety was evaluated throughout the study. Results Of 944 patients enrolled in the OLE study, the dose escalation subpopulation comprised 59 patients. In these patients, CR, MH and R rates 36 months after dose escalation were, respectively, 40.7%, 39.0% and 30.5% for NRI-LOCF and 95.2%, 86.4% and 66.7% for observed data (Table). Of these 59 patients, 29 had prior tumour necrosis factor inhibitor (TNFi) failure; in these patients, CR, MH and R rates at Month 36 were, respectively, 51.7%, 51.7% and 41.4% for NRI-LOCF, and 100.0%, 92,3% and 75.0% for observed data. Incidence rates for safety events and pt-years’ exposure are reported in the table. Conclusion For most patients who lost initial CR to tofacitinib 10 mg BID induction therapy while on tofacitinib 5 mg BID maintenance therapy, including those with prior TNFi failure, dose-escalation back to 10 mg BID recaptured CR by Month 2 and was generally maintained over 3 years. The safety profile with tofacitinib 10 mg BID in the dose-escalation subpopulation was generally consistent with that in the overall study population, although there was a numerically higher rate of herpes zoster. These analyses are limited by low pt numbers and the absence of a comparator arm. References

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of UC. Safety and efficacy of tofacitinib were demonstrated in Phase (P)2/3 induction studies, a 52-week, P3 maintenance study, and are being further investigated in an ongoing, open-label, long-term extension (OLE) study.1,2 Here, we provide an updated analysis of age as a risk factor for adverse events (AEs) in the tofacitinib UC clinical programme.3 Methods Proportions of AEs and serious AEs (SAEs), and incidence rates (IRs; unique patients with events per 100 patient-years) for AEs of special interest (AESIs), were determined for two cohorts: the Maintenance Cohort (patients who received placebo or tofacitinib 5 or 10 mg twice daily [BID] in the maintenance study) and the Overall Cohort (all tofacitinib 5 or 10 mg BID-treated patients in the P2/P3/OLE studies; as of May 2019), stratified by age. Multivariable Cox proportional hazards regression analyses were performed to assess whether older age was associated with increased risk of AESIs in the Overall Cohort. Results In the Maintenance Cohort, IRs of AEs and SAEs were generally similar between treatment groups, with no age-related trend in the proportions of AEs in tofacitinib-treated patients. AESIs were infrequent in both treatment groups; however, herpes zoster (HZ; non-serious and serious) IRs were numerically higher in the ≥40 to Conclusion In the Overall Cohort, there was a trend for an increase in the rates of OIs, HZ, malignancy (excl. NMSC) and NMSC with increasing age. In multivariate analyses, older age was associated with increased risk of malignancy (excl. NMSC), NMSC and HZ. The results of this analysis are generally consistent with previous studies suggesting older age may be associated with an increased risk of certain AESIs in patients with UC, and in some instances in the general population.4 References
