[PMID: 39367371 PMCID: PMC11451213 DOI: 10.1186/s12876-024-03341-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 07/25/2024] [Indexed: 10/06/2024] Open
Abstract
OBJECTIVE To evaluate the effectiveness and safety of tofacitinib in patients with ulcerative colitis (UC) in clinical practice in Lebanon. DESIGN This was a retrospective cross-sectional study. The data were collected from hospital records. Patients with moderate to severe UC treated with tofacitinib between 2018 and 2021 were included. Patients' demographics, disease-specific characteristics, clinical assessment at three time points (8, 26, and 52 weeks), endoscopic evaluation at 24 weeks, and adverse events were collected. RESULTS A total of 60 UC patients with a mean duration of disease of 7.9 ± 4.7 years were enrolled. 61.7% of patients had extensive disease, and 58.3% had received ≥ 1 biologic prior to tofacitinib. Clinical remission was reported in 25, 34, and 31 patients (41.7%, 56.7%, and 56.4%) at 8, 26, and 52 weeks respectively. Endoscopic remission (endoscopic Mayo score 0 or 1) was observed in 58.3% of patients at 52 weeks. About one-third of patients (31.7%) stopped tofacitinib at one year, primarily for lack of efficacy or loss of response, with no significant difference between biologics-naïve and experienced patients (24% vs. 37.1% respectively). No serious adverse events or deaths were reported. Adverse events were reported in 3 patients (5.0%) - one C. difficile infection, one case of reversible lymphopenia, and one case of facial acne. No serious adverse events or deaths were noted. On multivariate analysis, biologic-naïve status and reduction or normalization of CRP were associated with clinical remission (OR = 10.87, 95% CI = 1.57, 100, and OR = 78.47, 95% CI = 2.09, 2940.32 respectively), while reduction or normalization of CRP was associated with endoscopic remission at 1 year (OR = 19.03, 95% CI = 1.64, 221.09). CONCLUSION Tofacitinib was effective in the treatment of moderately severe ulcerative colitis in this real-world cohort in Lebanon. Further, the predictors associated with clinical and endoscopic remissions were found to be biologic-naïve status and reduction in CRP. Observed AEs were consistent with the known safety profile. One of the major limitations of this study is the smaller sample size and the retrospective nature of the study.

Abstract
INTRODUCTION The pathogenesis of inflammatory bowel disease (IBD) involves the dysregulation of multiple inflammatory pathways. The understanding of these mechanisms allows their selective targeting for therapeutic purposes. The discovery of Tumor Necrosis Factor-alpha's (TNF-α) role in mucosal inflammation ushered an exciting new era of drug development which now comprises agents targeting multiple pro-inflammatory signaling pathways, integrins, and leukocyte trafficking regulators. AREA COVERED This review provides an overview of the main molecular players of IBD, their translation into therapeutic targets and the successful development of the advanced agents modulating them. We combine basic science with clinical trials data to present a critical review of both the successful and failed drug development programs. A PubMed literature search was conducted to delve into the available literature and clinical trials. EXPERT OPINION The treatment landscape for IBD has rapidly expanded, particularly with the development of biologics targeting TNF-α, integrins, and S1P modulators, as well as newer agents such as IL-12/IL-23 inhibitors and JAK inhibitors, offering robust efficacy and safety profiles. However, challenges persist in understanding and effectively treating difficult-to-treat IBD, highlighting the need for continued research to uncover novel therapeutic targets and optimize patient outcomes.

Identifying potential inhibitors of C-X-C motif chemokine ligand10 against vitiligo: structure-based virtual screening, molecular dynamics simulation, and principal component analysis. J Biomol Struct Dyn 2024; 42:8045-8062. [PMID: 37565326 DOI: 10.1080/07391102.2023.2242952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 07/26/2023] [Indexed: 08/12/2023]
Abstract
The research aims to envisage small molecule inhibitors targeting the C-X-C motif chemokine ligand 10 (CXCL10) of the JAK/STAT pathway. CXCL10 plays a significant role in inducing auto-immunity in vitiligo through JAK/STAT pathway. To accomplish the aim, structure-based virtual screening with fundamental search limits, e.g., molecular weight (MW ≤ 500 Da), hydrogen bond donor (HBD ≤ 5), hydrogen bond acceptor (HBA ≤ 10), and lipophilicity (logP ≤ 5) was used to screen investigational molecules from MCULE database. The SBVS-ligand hits were sifted through toxicity profiling followed by filtration through the Brain or IntestinaL EstimateD-Egg model to check the human intestinal abortion and blood-brain barrier permeation based on two physicochemical properties, including topological surface area and WLOGP. The BOILED-Egg filtered compounds were passed through drug-likeness features other than Pfizer's Lipinski rule of five, viz., Ghose filters, Muegge filters, Egan parameters, and Veber filters, followed by medicinal chemistry's pan assay interference structure and Brenk alert investigation. Chemical compounds that comply with the above ADME descriptors were docked with target protein CXCL10 via AutoDock Vina. The stability of the top two ligand hits was assessed through dynamics simulations of 100 ns and principal component analysis and compared with the reference drugs Baicalein and EGCG. Based on the findings of Gibbs free energy of binding, ADME profiling, medicinal chemistry attributes depiction, root-mean-square deviation, root-mean-square fluctuation, solvent accessible surface area, the free energy of solvation, the radius of gyration, and PCA, MCULE2726078782-0-2 was found better than potential reference drug Baicalein.Communicated by Ramaswamy H.

Abstract
There are aspects of Janus kinase (JAK) inhibitors, specifically tofacitinib, that distinguish them from other drugs used in the treatment of ulcerative colitis (UC), such as their oral administration, their short half-life and their lack of immunogenicity. With the available evidence, we can highlight tofacitinib's quick action and flexibility of use, and its efficacy in patients, irrespective of whether or not they have previously been exposed to TNF inhibitors (anti-TNF drugs) and other biologic agents. Moreover, their safety profile is known and manageable, with certain considerations and precautions being factored in before and during treatment. In this review, we have defined various scenarios pertaining to this drug, e.g. its use in the event of failure or intolerance to previous treatment with biologics, when a quick response is required or in patients with other concurrent immune-mediated diseases.

Real-world efficacy and safety of tofacitinib treatment in Asian patients with ulcerative colitis. World J Gastroenterol 2024; 30:1871-1886. [PMID: 38659488 PMCID: PMC11036499 DOI: 10.3748/wjg.v30.i13.1871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 01/30/2024] [Accepted: 03/13/2024] [Indexed: 04/03/2024] Open
Abstract
BACKGROUND Real-world data on tofacitinib (TOF) covering a period of more than 1 year for a sufficient number of Asian patients with ulcerative colitis (UC) are scarce. AIM To investigate the long-term efficacy and safety of TOF treatment for UC, including clinical issues. METHODS We performed a retrospective single-center observational analysis of 111 UC patients administered TOF at Hyogo Medical University as a tertiary inflammatory bowel disease center. All consecutive UC patients who received TOF between May 2018 and February 2020 were enrolled. Patients were followed up until August 2020. The primary outcome was the clinical response rate at week 8. Secondary outcomes included clinical remission at week 8, cumulative persistence rate of TOF administration, colectomy-free survival, relapse after tapering of TOF and predictors of clinical response at week 8 and week 48. RESULTS The clinical response and remission rates were 66.3% and 50.5% at week 8, and 47.1% and 43.5% at week 48, respectively. The overall cumulative clinical remission rate was 61.7% at week 48 and history of anti-tumor necrosis factor-alpha (TNF-α) agents use had no influence (P = 0.25). The cumulative TOF persistence rate at week 48 was significantly lower in patients without clinical remission than in those with remission at week 8 (30.9% vs 88.1%; P < 0.001). Baseline partial Mayo Score was significantly lower in responders vs non-responders at week 8 (odds ratio: 0.61, 95% confidence interval: 0.45-0.82, P = 0.001). Relapse occurred in 45.7% of patients after TOF tapering, and 85.7% of patients responded within 4 wk after re-increase. All 6 patients with herpes zoster (HZ) developed the infection after achieving remission by TOF. CONCLUSION TOF was more effective in UC patients with mild activity at baseline and its efficacy was not affected by previous treatment with anti-TNF-α agents. Most relapsed patients responded again after re-increase of TOF and nearly half relapsed after tapering off TOF. Special attention is needed for tapering and HZ.

Abstract
Ulcerative colitis (UC) has seen a significant increase over the past 3 decades. However, our understanding of its etiology, pathogenesis, and pharmacological treatment remains limited. This comprehensive review aims to address these gaps by analyzing trends, evaluating previous research, and providing insights for future investigations. We conducted a bibliometric analysis of UC-related papers indexed in the Web of Science from 1993 to 2022. The author, organization, country, and keyword networks in the field of UC were visualized. A total of 36,483 papers were included, showing a continuous upward trend. Most research on UC was conducted in universities, with hospitals leading in high-quality studies. The United States emerged as the primary contributor, followed by China and the United Kingdom. The overall quality of UC-related publications improved, indicating sustained interest in the field. The keywords related to UC was classified into 9 clusters. Keywords detection revealed that UC research focused mainly on the discovery of its etiology and exploration of treatment methods, with research directions evolving from initial treatment of UC and related diseases to clinical trials of UC and subsequently incorporating genomics and bioinformatics techniques to study UC and explore new therapeutic methods and drugs, including recent advances in gut microbiota. Our study identified gaps in understanding the etiology, pathogenesis, and treatment of UC. Future research in UC should focus on genomics, personalized treatment, microbial therapy and leveraging machine learning and artificial intelligence. These areas hold the potential for improving UC diagnosis, treatment, and management.

Abstract
OBJECTIVES Tofacitinib is a Janus Kinase inhibitor used for treating moderate to severe ulcerative colitis (UC), mainly after the failure of biological therapy. There is a paucity of data on the outcome of tofacitinib in biological-naïve UC patients. The present study was aimed at analyzing the safety and efficacy of tofacitinib in biological-naïve Indian patients with UC. METHODS The present study retrospectively evaluated consecutive patients with biological-naïve moderate-to-severe active UC from six tertiary care centers in India receiving tofacitinib from September 2020 to September 2022. Clinical remission or response assessment was based on partial Mayo score (PMS) calculated at baseline and weeks eight, 16 and 24. RESULTS Total 47 cases (57.4% male, median age: 32 years) were included. After eight weeks of therapy, 33 (70.2%) achieved clinical remission and eight (17.0%) had a primary failure. The baseline serum albumin at treatment initiation was the only independent predictor of remission at eight weeks (Odds ratio: 11.560, 95% CI: 1.478 - 90.404), but not at 16 weeks. By 24 weeks, 59.6% (28/47) of the patients were in remission and 29.8% (14/47) had stopped tofacitinib either due to failure (27.6%) or adverse events (AEs) (2.1%). Among the 47 patients, 10 (21.2%) cases developed AEs during follow-up, including two tuberculosis (4.2%), one cytomegalovirus (CMV) colitis (2.1%) and one herpes zoster (2.1%). Four patients with infection required temporary drug discontinuations. One required permanent discontinuation (mania). CONCLUSION Upfront tofacitinib is effective in biologic-naïve Indian patients with moderate-severe UC. Further randomized studies are required to validate the study findings.

Abstract
BACKGROUND Inflammatory skin diseases (ISDs), are characterized by dysregulated activation of innate and adaptive immune systems, with inflammatory cytokines playing a crucial role in their pathogenesis. OBJECTIVES This study aimed to investigate the involvement of Janus kinase/signal transduction and activator of transcription (JAK/STAT) signaling pathway in the pathogenesis of ISDs. METHODS The study analyzed a total of 117 skin biopsies, comprising 31 from pyoderma gangrenosum (PG), 25 from hidradenitis suppurativa (HS), 35 from psoriasis patients, and 26 from control subjects. To assess the expression levels of JAK/STAT pathway components, immunohistochemical staining was performed on both the dermal and epidermal layers of the skin. The Histo score (H score) was utilized as the immunoexpression score to evaluate the staining intensity. RESULTS The results indicated that all components of the JAK/STAT signaling pathway, except JAK2 and STAT6 in PG, JAK1, STAT4, and STAT6 in HS, and JAK1 in psoriasis, were overexpressed in the dermal skin compared to the control group (p < 0.05). Psoriatic skin had higher expression of STAT6 than both PG and HS and higher expression of JAK2 than PG (p < 0.05). Additionally, HS biopsies had higher expression of JAK2 and STAT6 compared to PG (p < 0.05). JAK1 expression was higher in PG than in HS, psoriasis, and the control group (mean H score was 265.8, 184.8, 191.4, and 113.1, p < 0.05, respectively). CONCLUSIONS This study provides new insights into the potential contribution of the JAK/STAT pathway to the pathogenesis of ISDs. The findings suggest that targeting this pathway could be a promising therapeutic strategy for treating these disorders.

Abstract
BACKGROUND The etiopathogenesis of accompanying inflammatory phenomena and consequences of immunomodulation constitute a challenging and innovative field in the medical treatment of patients with autoimmune diseases. AIM Based on i) clinical management experience gained from this challenging clinical case and ii) selective references of reports published in the scientific medical literature, we present an unusual counterfactual scientific case report. A patient diagnosed with ulcerative colitis undergoing januskinase (JAK)-inhibitor therapy developed acuteappendicitis as an unusual complication or as a visceral side effect of immunosuppressive/anti-inflammatory therapy. METHOD Scientific case report. RESULTS (case description): Medical history: A 52-year-old male presented with spasmodic pain in the right lower abdomen lasting for two days (no fever, no bowel movement changes (no stool irregularities), no vomiting). MEDICATION USED TO DATE Steroid-resistant ulcerative colitis treated with immunosuppressive therapy (Adalimumab administered for 10 months [next generation anti-TNFα mAb], Vendolizumab for 9 months [α4β7 integrin antagonist], Tofacitinib for 6 months); fructose intolerance, no previous abdominal surgery; medication: XeljanzTM (Tofacitinib, 5 mg 2x1; JAK-inhibitor; PFIZER PHARMA GmbH, Berlin,Germany); MutaflorTM (1x1; Ardeypharm GmbH, Herdecke, Germany). CLINICAL FINDINGS Pressure pain in the right lower abdomen with local muscular defense (Mc-Burney's/Lanz's point positive), no peritonism, Psoas-muscle sign positive. DIAGNOSTIC MEASURES Laboratory parameters: standard value of white blood cell count, CrP: 25 mg/l.-Transabdominal ultrasound revealed hypertrophic 'appendix vermiformis' with detectable target-phenomenon and surrounding fluid. DECISION-MAKING Indication for laparoscopic exploration. THERAPY Under perioperative single-shot antibiotic administration with UnacidTM, the patient underwent emergency laparoscopic appendectomy due to confirmed acute appendicitis with additional lavage and placement of local drainage. CLINICAL COURSE The postoperative phase was uneventful (sufficient analgetic therapy, removal of local drainage on the 2nd postoperative day). The patient was discharged four days after surgery. Histopathology confirmed ulcero-phlegmonous, acute purulent appendicitis with fibrinous purulent mesenteriolitis. FURTHER MEASURES Immunosuppressive therapy was continued. CONCLUSION Based on the paradoxon of an acute inflammatory disease (acute appendicitis) seen in the case of a patient undergoing immunosuppressive/anti-inflammatory treatment using a JAK-Inhibitor for ulcerative colitis, we consider this case worthy of publication although this side effect has previously been described in patients with rheumatoid arthritis. This might be the manifestation of i) an immunomodulatory effect that reduced or at least altered mucosal defense, including an increased risk of opportunistic infections, presenting as a specific visceral 'side effect' of the JAK-Inhibitor and/or as a consequence; ii) an induced alternative inflammatory mechanism/proinflammatory signal transduction and - theoretically - an intestinal drainage defect in the segment of right colic artery with consecutive collection of necrotic cells and activation of inflammatory mediators.

Abstract
Background and aims Acute severe steroid-refractory ulcerative colitis remains a medically challenging condition with frequent need of surgery. It can be treated with the calcineurin inhibitor cyclosporine A with the need for therapeutic drug monitoring and significant toxicity. Recently, a novel calcineurin inhibitor, voclosporin, has been approved for the treatment of lupus nephritis with no need for therapeutic drug monitoring and an improved long-term safety profile. However, the therapeutic effect of voclosporin in acute severe steroid-refractory ulcerative colitis is still uncertain. We aimed to assess the therapeutic potential of voclosporin to ameliorate inflammation in an experimental model of colitis. Methods We used the dextran sodium sulfate-induced model of colitis in C57BL/6 J wildtype mice treated with either cyclosporine A, voclosporin or solvent control. We employed endoscopy, histochemistry, immunofluorescence, bead-based multiplex immunoassays and flow cytometry to study the therapeutic effect of calcineurin inhibitors in a preventive setting. Results Acute colitis was induced by dextran sodium sulfate characterized by weight loss, diarrhea, mucosal erosions and rectal bleeding. Both cyclosporine A and voclosporin strongly ameliorated the course of disease and reduced colitis severity in a similar manner. Conclusion Voclosporin was identified as biologically effective in a preclinical model of colitis and may be a potential therapeutic option in treating acute severe steroid-refractory ulcerative colitis.

Cost-Effectiveness Analysis of Tofacitinib Compared with Biologics in Biologic-Naïve Patients with Moderate-to-Severe Ulcerative Colitis in Japan. PHARMACOECONOMICS 2023; 41:589-604. [PMID: 36884164 PMCID: PMC10085930 DOI: 10.1007/s40273-023-01254-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Accepted: 02/12/2023] [Indexed: 05/10/2023]
Abstract
OBJECTIVE Tofacitinib is an oral Janus kinase inhibitor approved for the treatment of ulcerative colitis (UC). The objective of this study was to evaluate the long-term cost-effectiveness of tofacitinib versus current biologics, considering combinations of first-line (1L) and second-line (2L) therapies, from a Japanese payer's perspective in patients with moderate-to-severe active UC following an inadequate response to conventional therapy and in those who were naïve to biologics. METHODS A cost-effectiveness analysis was conducted during the time horizon specified in the Markov model, which considers a patient's lifetime as 60 years and an annual discount rate of 2% on costs and effects. The model compared tofacitinib with vedolizumab, infliximab, adalimumab, golimumab, and ustekinumab. The time of active treatment was divided into induction and maintenance phases. Patients not responding to their biologic treatment after induction or during the maintenance phase were switched to a subsequent line of therapy. Treatment response and remission probabilities (for induction and maintenance phases) were obtained through a systematic literature review and a network meta-analysis that employed a multinomial analysis with fixed effects. Patient characteristics were sourced from the OCTAVE Induction trials. Mean utilities associated with UC health states and adverse events (AEs) were obtained from published sources. Direct medical costs related to drug acquisition, administration, surgery, patient management, and AEs were derived from the JMDC database analysis, which corresponded with the medical procedure fees from 2021. The drug prices were adjusted to April 2021. Further validation through all processes by clinical experts in Japan was conducted to fit the costs to real-world practices. Scenario and sensitivity analyses were also performed to confirm the accuracy and robustness of the base-case results. RESULTS In the base-case, the treatment pattern including 1L tofacitinib was more cost-effective than vedolizumab, infliximab, golimumab, and ustekinumab for 1L therapies in terms of cost per quality-adjusted life year (QALY) gained (based on the Japanese threshold of 5,000,000 yen/QALY [38,023 United States dollars {USD}/QALY]). The base-case results demonstrated that the incremental costs would be reduced for all biologics, and decreases in incremental QALYs were observed for all biologics other than adalimumab. The incremental cost-effectiveness ratio (ICER) was found to be dominant for adalimumab; for the other biologics, it was found to be less costly and less efficacious. The efficiency frontier on the cost-effectiveness plane indicated that tofacitinib-infliximab and infliximab-tofacitinib were more cost-effective than the other treatment patterns. When infliximab-tofacitinib was compared with tofacitinib-infliximab, the ICER was 282,609,856 yen/QALY (2,149,157 USD/QALY) and the net monetary benefit (NMB) was -12,741,342 yen (-96,894 USD) with a threshold of 5,000,000 yen (38,023 USD) in Japan. Therefore, infliximab-tofacitinib was not acceptable by this threshold, and tofacitinib-infliximab was the cost-effective treatment pattern. CONCLUSION The current analysis suggests that the treatment pattern including 1L tofacitinib is a cost-effective alternative to the biologics for patients with moderate-to-severe UC from a Japanese payer's perspective.

Comparative Efficacy of Infliximab Versus Tofacitinib for Inducing Remission in Biologic Naive Ulcerative Colitis: A Propensity Matched Study. Dig Dis Sci 2023; 68:2635-2646. [PMID: 37119375 DOI: 10.1007/s10620-023-07956-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Accepted: 04/23/2023] [Indexed: 05/01/2023]
Abstract
OBJECTIVE In the absence of head-to-head clinical trials, indirect comparative studies are needed to help position therapies in ulcerative colitis (UC). We aimed to compare the efficacy of infliximab vs. tofacitinib for moderate-severe UC among biologic-naïve participants at post-induction. METHODS This was a post-hoc analysis of patient-level data from four clinical trials including 659 biologic-naïve UC participants. We compared proportions of patients achieving week 8 clinical remission (CR), endoscopic improvement, and endoscopic remission. Clinical response at week 2 was also assessed. Multiple logistic regression models were adjusted for potential confounders identified as having an association with the outcome of interest on univariate analysis. Propensity scores were calculated to create a cohort of participants with similar distribution of baseline co-variates. RESULTS Patients treated with infliximab had significantly greater odds of CR at week 8 compared to tofacitinib [88/242 (36.4%) vs. 100/417 (24.0%), aOR: 1.65 (95% CI 1.11-2.44), p = 0.013]. Endoscopic improvement at week 8 was also significantly greater among infliximab-treated patients [149/242 (61.6%) vs. 159/417 (38.1%), aOR: 2.12 (95% CI 1.45-3.10), p < 0.001]. Similar findings were observed with week 8 endoscopic remission [61/242 (25.2%) vs. 43/417 (10.3%); aOR: 2.72 (95% CI 1.66-4.46), p < 0.001]. A similar proportion of participants attained clinical response at week 2 [205/242 (84.7%) vs. 334/417 (80.1%), aOR: 1.48 (95% CI 0.93-2.37), p = 0.101]. Similar results were observed among the propensity score matched cohort. CONCLUSION Based on the efficacy observed in this post-hoc analysis, consideration should be given to use of infliximab over tofacitinib for treatment of moderate to severe biologic-naïve UC. However, baseline characteristic mismatches persisted despite propensity score matching, and further studies are needed to confirm our findings.

Abstract
In recent years, better knowledge of the pathophysiology of inflammatory bowel diseases (IBD) has led to a relevant expansion of the therapeutic arsenal for these conditions. Janus kinase (JAK) inhibitors are a family of small molecules that block one or more of the intracellular tyrosine kinases, including JAK-1, JAK-2, JAK-3 and TYK-2. Tofacitinib, a non-selective small molecule JAK inhibitor, and upadacitinib and filgotinib, which are selective JAK-1 inhibitors, have been approved by the US Food and Drug Administration (FDA) for moderate-to-severe active ulcerative colitis. Compared to biological drugs, JAK inhibitors have a short half-life, rapid onset of action, and no immunogenicity. Both clinical trials and real-world evidence support the use of JAK inhibitors in the treatment of IBD. However, these therapies have been linked with multiple adverse events (AEs) including infection, hypercholesterolemia, venous thromboembolism, major adverse cardiovascular events, and malignancy. While early studies recognized several potential AEs, post-marketing trials have shown that tofacitinib may increase the risk of thromboembolic diseases and major cardiovascular events. The latter are seen in patients aged 50 years or older with cardiovascular risk factors. Hence, the benefits of treatment and risk stratification need to be considered when positioning tofacitinib. Novel JAK inhibitors with a more selective effect on JAK-1 have proven to be effective in both Crohn's disease and ulcerative colitis, offering a potentially safer and efficacious therapeutic option to patients, including those with previous non-response to other therapies such as biologics. Nevertheless, long-term effectiveness and safety data are required.

Abstract
Therapeutic options for the management of inflammatory bowel disease [IBD] have been expanding in recent decades. New biological and small molecule therapies have been incorporated into the pharmacological arsenal, allowing a more personalized management, and seeking increasingly strict remission goals. However, the fear of developing adverse events represents one of the most important limitations in deciding its use by patients and by a multidisciplinary team. Despite the risk of hepatotoxicity of thiopurines and methotrexate, these drugs are still used either as monotherapy or as combined therapy with anti-tumour necrosis factor [anti-TNF] biological agents. Although drug-induced liver injury [DILI] appears to be less frequent with anti-TNF agents, newer biologics and small molecules, liver tests should be considered in the follow-up of these patients, especially regarding future combined therapy of biologics or of these drugs with small molecules. The objective of this review is to show data on the risk of developing DILI in patients with IBD who are undergoing treatment with traditional therapy or new drugs, whether biological or small molecules.

Abstract
INTRODUCTION Tofacitinib has emerged as a useful drug for the treatment of ulcerative colitis (UC). AREAS COVERED There is an unmet need for cost-effective, non-immunogenic drugs with a safe adverse effect profile to treat patients with ulcerative colitis. In the present review, we evaluate the available literature to inform the appropriate positioning of tofacitinib in the current drug landscape and identify subsets where its use should be done with caution. EXPERT OPINION Tofacitinib is helpful in the treatment of patients where the standard conventional or biological therapies have failed or were not tolerated. With lower costs of the generic drug than the biologicals (or biosimilars), it could be an important therapy in low- to middle-income countries. The risk of infections, especially Herpes Zoster and tuberculosis, needs to be addressed before initiation. Tofacitinib should be avoided in patients with venous thromboembolism and cardiovascular disease risk factors. Due to limited evidence, the use is not recommended in pregnancy, while it should be used with caution in elderly citizens. Future trials should look into the head-to-head comparison of tofacitinib with biologicals. The role of tofacitinib in acute severe colitis needs evaluation with comparative trials with current standards of care.

Abstract
OBJECTIVE This real-world study evaluated biologic treatment patterns in patients with moderate-to-severe ulcerative colitis (UC). METHODS IQVIA PharMetrics, IBM MarketScan, and Optum Clinformatics were pooled to identify UC patients with ≥1 claim for UC and ≥1 claim for adalimumab (ADA), golimumab (GOL), infliximab (IFX), or vedolizumab (VDZ). The index date for each biologic was the first claim for that biologic. Patients could be included in >1 cohort if they switched biologics during the identification period. Continuous eligibility for medical/pharmacy benefits was required for 12 months before (baseline) and after (follow-up) the index date. Patients lacking claims for any biologic during baseline were categorized as bio-naïve; those with any biologic claim were categorized as bio-experienced. Persistence was defined as the proportion of patients that remained on the index biologic without a gap between claims of >28 days for ADA, >56 days for GOL, and >112 days for IFX and VDZ. Dose titration was assessed among patients with ≥2 maintenance doses during follow-up among ADA, GOL, and VDZ patients. RESULTS In total, 6,106 bio-naïve UC patients and 1,027 bio-experienced UC patients were identified. Patients treated with VDZ and IFX had the highest persistence followed by ADA and GOL patients for bio-naïve and bio-experienced, respectively. ADA patients had a numerically higher proportion of patients with 50% dose escalation, followed by VDZ and GOL; 50% dose reduction was observed in ≤1% patients. CONCLUSIONS In this descriptive study of UC patients without confounder adjustment, VDZ persistence was numerically highest followed by IFX, GOL, and ADA across both populations.

Abstract
Upadacitinib is a selective small molecule that inhibits Janus kinase (JAK) type 1. This molecule is administrated orally and is currently approved for the treatment of rheumatoid arthritis, atopic dermatitis, and psoriatic arthritis. Upadacitinib has been approved by the United States Food and Drug Administration for the induction and maintenance therapy of moderate-to-severe ulcerative colitis (UC) and is under investigation by the European Medicines Agency. Data from two induction and two maintenance Phase III randomized controlled trials (RCTs) proved the efficacy of upadacitinib in achieving clinical and endoscopic remission in patients with moderate-to-severe UC, regardless of previous inadequate response to other biologic therapies. The most frequently reported adverse events in the induction trials were acne, creatine phosphokinase increase, nasopharyngitis, headache, and anemia, while in the maintenance studies nasopharyngitis, elevation of creatine phosphokinase, UC exacerbation, upper respiratory tract infection, arthralgia, and anemia were reported. A limited proportion of upadacitinib-treated patients experienced adverse events of special interest, like herpes zoster infections or thromboembolic events, indicating a reliable safety profile. The aim of this review is to summarize the available evidence on upadacitinib in UC providing useful insights about the positioning of this drug in the therapeutic algorithm.

Abstract
BACKGROUND In ulcerative colitis (UC), the molecular mechanisms that drive disease development and patient response to therapy are not well understood. A significant proportion of patients with UC fail to respond adequately to biologic therapy. Therefore, there is an unmet need for biomarkers that can predict patients' responsiveness to the available UC therapies as well as ascertain the most effective individualised therapy. Our study focused on identifying predictive signalling pathways that predict anti-integrin therapy response in patients with UC. METHODS We retrieved and pre-processed two publicly accessible gene expression datasets (GSE73661 and GSE72819) of UC patients treated with anti-integrin therapies: (1) 12 non-IBD controls and 41 UC patients treated with Vedolizumab therapy, and (2) 70 samples with 58 non-responder and 12 responder UC patient samples treated with Etrolizumab therapy without non-IBD controls. We used a diffusion-based signalling model which is mainly focused on the T-cell receptor signalling network. The diffusion model uses network connectivity between receptors and transcription factors. RESULTS The network diffusion scores were able to separate VDZ responder and non-responder patients before treatment better than the original gene expression. On both anti-integrin treatment datasets, the diffusion model demonstrated high predictive performance for discriminating responders from non-responders in comparison with 'nnet'. We have found 48 receptor-TF pairs identified as the best predictors for VDZ therapy response with AUC ≥ 0.76. Among these receptor-TF predictors pairs, FFAR2-NRF1, FFAR2-RELB, FFAR2-EGR1, and FFAR2-NFKB1 are the top best predictors. For Etrolizumab, we have identified 40 best receptor-TF pairs and CD40-NFKB2 as the best predictor receptor-TF pair (AUC = 0.72). We also identified subnetworks that highlight the network interactions, connecting receptors and transcription factors involved in cytokine and fatty acid signalling. The findings suggest that anti-integrin therapy responses in cytokine and fatty acid signalling can stratify UC patient subgroups. CONCLUSIONS We identified signalling pathways that may predict the efficacy of anti-integrin therapy in UC patients and personalised therapy alternatives. Our results may lead to the advancement of a promising clinical decision-making tool for the stratification of UC patients.

Abstract
Tofacitinib has emerged as a new option for ulcerative colitis. Its rapid absorption, metabolism, and clinical improvement make it an interesting option for rescue therapy in acute severe ulcerative colitis (ASUC), a situation with limited therapeutic options in patients with a long-term disease course and multiple drug failure. The management of ASUC in this setting becomes challenging, underlying the need for new drugs and data on their efficacy and safety. We describe 2 cases of acute episodes in which tofacitinib was used as a rescue therapy.

Abstract
Inflammatory bowel diseases (IBD) are associated with various hepatobiliary disorders. They can occur at any moment in the course of the disease or associated with the treatment. The prevalence of liver dysfunction can reach up to 50% in different studies. Nonalcoholic fatty liver disease is considered the most common hepatobiliary complication in IBD, while primary sclerosing cholangitis is the most specific. Management of hepatic manifestations in IBD involves a multidisciplinary approach that includes a high index of suspicion and joint management with hepatologists. The medical confrontation with abnormal liver tests must include an exhaustive study to determine if these patterns can be related to IBD, associated diseases or to the therapies used.

Abstract
INTRODUCTION Crohn's disease (CD) is a chronic, relapsing inflammatory bowel disease that can lead to significant organ damage and impaired quality of life. To date, a considerable proportion of patients does not respond to biologic compounds. It is, therefore, necessary to find alternative options with adequate efficacy and safety profiles in order to increase the chances of obtaining an enduring remission of disease. Janus kinase (JAK) inhibitors are a new class of compounds that might well serve this purpose. The aim of our review is to report the available data from clinical trials testing these new drugs in patients suffering from CD. AREAS COVERED PubMed database and ClinicalTrials.gov website were consulted in order to find the clinical trials evaluating the efficacy and safety profiles of JAK-inhibitors in CD patients, including the following compounds: tofacitinib, filgotinib, upadacitinib, TD-1473, and Pf-06651600/Pf-06700841. EXPERT OPINION JAK-inhibitors are a promising class of oral compounds in moderate-severe CD. Further clinical trials are necessary in order to implement the available knowledge, especially on their long-term safety issues.

Abstract
Ulcerative colitis (UC) is an incurable, chronic inflammatory disease of the large bowel whose etiology and pathogenesis have not yet been comprehensively explained. Tofacitinib is a small molecule Janus kinase inhibitor that was introduced for treating refractory UC. We aimed to examine the efficacy and safety of tofacitinib for the treatment of 18 patients with UC. Continuous treatment rates were 50, 38, and 33% at 8, 24, and 52 weeks, respectively. Overall, 83.3% of these patients showed tumor necrosis factor (TNF) antibody failure status. When the effective status was defined as a Lichtiger index (LI) that decreased by 3 points or more or was less than 4 points and remission status was defined as an LI less than 4 points, the effective and remission rates (%) at 2, 8, and 16 weeks were 55.5 (10/18) and 22.2 (4/18), 38.8 (7/18) and 33.3 (6/18), and 38.8 (7/18) and 38.8 (7/18), respectively. Background characteristics of 2-week responders and non-responders were compared. C-reactive protein level in responders was significantly lower than that in non-responders, and the hemoglobin level in responders was significantly higher than that in non-responders. This study provides preliminary results of the effectiveness of tofacitinib even for TNF antibody and tacrolimus failure patients.

Abstract
BACKGROUND We sought to define the effectiveness and safety of tofacitinib in a real-world (RW) cohort of Israeli patients with moderate to severe ulcerative colitis (UC). METHODS This was a multi-center retrospective observational cohort study (2019-2020) to assess the effectiveness and safety of tofacitinib induction and maintenance therapy up to 26 weeks. Clinical response and remission were defined as a reduction in Simple Clinical Colitis Activity Index (SCCAI) or partial Mayo score (PMS) of ≥3 points, and SCCAI ≤2 or a PMS ≤1, respectively. RESULTS We included 73 patients, 47% male; median age 26 years [IQR: 19.5-39.5], disease duration 7 years [IQR: 2.5-14.5], follow-up 7.1 months [IQR: 3-12], 91% biologics-experienced, and 74% ≥ 2-biologics. Half of patients used concomitant corticosteroids (CS). Overall, 56.1% discontinued therapy due to either lack of response and/or adverse events (AEs), median time to discontinuation - 9.7 months [IQR 3.4-16]. Overall, response, remission, and CS-free-remission were achieved in 47.6%, 20.6%, and 17.5% of patients, respectively. At early maintenance (week 26), response, remission, and CS-free-remission were achieved in 65%, 22.5%, and 20% of patients, respectively. At week 26, tofacitinib 10 mg BID was still used in 43%. Seventeen patients (23.2%) had an adverse event including herpes zoster- 2.7%, hospitalization- 12.3%, and colectomy- 2.7%. CONCLUSIONS Tofacitinib was effective in achieving CS-free-remission in about 1/5 of highly biologics -experienced patients with UC. Despite a considerable proportion of patients maintained on tofacitinib 10 mg bid, it was well tolerated and safe. Earlier positioning of tofacitinib in the therapeutic algorithm may result in improved outcomes.

Abstract
BACKGROUND In this systematic review, our objective was to assess inflammatory bowel disease (IBD) patient preferences and perspectives relating to their disease diagnosis, treatment, knowledge needs and telemedicine. METHODS This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Four databases and conference proceedings were searched between January 1, 1980, and May 1, 2020. The methodological quality of the included studies was assessed using the Standards for reporting qualitative research checklist. RESULTS Our search identified 240 citations and 52 studies met the inclusion criteria. The major expectations of the patients are symptomatic and pain control, quality of life and normal endoscopy. Patients' main concerns are access to information and healthcare, and shared decision making. At the time of diagnosis, patients expressed a greater need for knowledge about their IBD, preferentially by their treating gastroenterologist. The main treatment expectations in active disease are efficacy, safety and convenience. Patients are willing to accept relatively high risks of complications from medical therapy to avoid a permanent ostomy and to achieve durable remission. Patients are more interested in disease monitoring, research and development during the time of remission. Telemedicine and self-management with supervised e-health tools are feasible and acceptable amongst patients with IBD. CONCLUSION This systematic review demonstrates that patients with IBD expect more information about their disease process, shared decision making and symptom control. Further research is needed to help align patient and physician expectations in order to improve the quality of care provided to patients with IBD.

Abstract
Hepatobiliary disorders are among the most common extraintestinal manifestations in inflammatory bowel diseases (IBD), both in Crohn’s disease and ulcerative colitis (UC), and therefore represent a diagnostic challenge. Immune-mediated conditions include primary sclerosing cholangitis (PSC) as the main form, variant forms of PSC (namely small-duct PSC, PSC-autoimmune hepatitis overlap syndrome and IgG4-related sclerosing cholangitis) and granulomatous hepatitis. PSC is by far the most common, presenting in up to 8% of IBD patients, more frequently in UC. Several genetic foci have been identified, but environmental factors are preponderant on disease pathogenesis. The course of the two diseases is typically independent. PSC diagnosis is based mostly on typical radiological findings and exclusion of secondary cholangiopathies. Risk of cholangiocarcinoma is significantly increased in PSC, as well as the risk of colorectal cancer in patients with PSC and IBD-related colitis. No disease-modifying drugs are approved to date. Thus, PSC management is directed against symptoms and complications and includes medical therapies for pruritus, endoscopic treatment of biliary stenosis and liver transplant for end-stage liver disease. Other non-immune-mediated hepatobiliary disorders are gallstone disease, whose incidence is higher in IBD and reported in up to one third of IBD patients, non-alcoholic fatty liver disease, pyogenic liver abscess and portal vein thrombosis. Drug-induced liver injury (DILI) is an important issue in IBD, since most IBD therapies may cause liver toxicity; however, the incidence of serious adverse events is low. Thiopurines and methotrexate are the most associated with DILI, while the risk related to anti-tumor necrosis factor-α and anti-integrins is low. Data on hepatotoxicity of newer drugs approved for IBD, like anti-interleukin 12/23 and tofacitinib, are still scarce, but the evidence from other rheumatic diseases is reassuring. Hepatitis B reactivation during immunosuppressive therapy is a major concern in IBD, and adequate screening and vaccination is warranted. On the other hand, hepatitis C reactivation does not seem to be a real risk, and hepatitis C antiviral treatment does not influence IBD natural history. The approach to an IBD patient with abnormal liver function tests is complex due to the wide range of differential diagnosis, but it is of paramount importance to make a quick and accurate diagnosis, as it may influence the therapeutic management.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder in which inflammation and oxidative stress play key etiopathological role. The pathology of PD brain is characterized by inclusions of aggregated α-synuclein (α-SYN) in the cytoplasmic region of neurons. Clinical evidence suggests that stimulation of pro-inflammatory cytokines leads to neuroinflammation in the affected brain regions. Upon neuroinflammation, the Janus Kinase/Signal Transducers and Activators of Transcription (JAK/STAT) signaling pathway, and other transcription factors such as nuclear factor κB (NF-κB), NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3), mammalian target of rapamycin (mTOR), and toll-like receptors (TLRs) are upregulated and induce the microglial activation, contributing to PD via dopaminergic neuron autophagy. Aberrant activation or phosphorylation of the components of JAK/STAT signaling pathway has been implicated in increased transcription of the inflammation-associated genes and many neurodegenerative disorders such as PD. Interferon gamma (IFN-γ), and interleukine (IL)-6 are two of the most potent activators of the JAK/STAT pathway, and it was shown to be elevated in PD. Stimulation of microglial cell with aggregated α-SYN results in production of nitric oxide (NO), tumor necrosis factor (TNF)-α, and IL-1β in PD. Dysregulation of the JAK/STAT in PD and its involvement in various inflammatory pathways make it a promising PD therapy approach. So far, a variety of synthetic or natural small-molecule JAK inhibitors (Jakinibs) have been found promising in managing a spectrum of ailments, many of which are in preclinical research or clinical trials. Herein, we provided a perspective on the function of the JAK/STAT signaling pathway in PD progression and gathered data that describe the rationale evidence on the potential application of Jakinibs to improve neuroinflammation in PD.

D’Amico F, Magro F, Peyrin-Biroulet L, Danese S. Positioning Filgotinib in the Treatment Algorithm of Moderate to Severe Ulcerative Colitis. J Crohns Colitis 2021; 16:835-844. [PMID: 34791103 PMCID: PMC9228886 DOI: 10.1093/ecco-jcc/jjab206] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 10/19/2021] [Accepted: 11/12/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIMS Filgotinib is a small molecule that selectively inhibits Janus kinase [JAK] type 1. It is already approved for the treatment of rheumatoid arthritis and is being evaluated for the management of patients with moderate to severe ulcerative colitis [UC]. The purpose of this review is to provide an overview of the currently available data on filgotinib and to define how to position this new drug in the treatment algorithm of patients with UC. METHODS The Pubmed, Embase and Scopus databases were searched up to June 25, 2021 in order to identify studies reporting efficacy and safety data of filgotinib in patients with UC. RESULTS Data from a phase III study enrolling UC patients with moderate to severe disease show that filgotinib is effective with a reassuring safety profile. Filgotinib treatment is not associated with a greater risk of thrombosis and herpes zoster infections compared to other JAK inhibitors. However, animal studies reported impaired spermatogenesis and histopathological effects on male reproductive organs, making it necessary to deepen this aspect in dedicated human studies. CONCLUSIONS Filgotinib is an effective and safe drug for treatment of both biologic-naive and biologic-experienced patients with moderate to severe UC and may soon be available.

Abstract
Crohn disease (CD) and ulcerative colitis (UC) are considered chronic disorders of the gastrointestinal tract, lifelong medication often being necessary. Furthermore, they have significant implications on the quality of life. In the past few years, major advances have been achieved concerning the treatment of inflammatory bowel disease. These advances are expanding the possibilities for managing these patients. Janus kinase (JAK) inhibitors represent the most auspicious treatment to date because they consist of drugs that are orally administered, with a short half-life and low antigenicity. In addition, they seem to concurrently lessen various proinflammatory routes. In fact, tofacitinib has already been approved in patients with UC, both naïve and with prior exposure to tumor necrosis factor inhibitors. In CD, the results with tofacitinib have been less impressive. Several other JAK inhibitors are currently being investigated. However, given the wide spectrum of immunosuppressive effects, special attention has been given to the safety profile of these drugs, namely with regard to the occurrence of thromboembolic events, opportunistic infections, and malignancy. In this article, we review key evidence on the efficacy and safety of JAK inhibitors concerning both UC and CD.

Abstract
BACKGROUND Vedolizumab is a widely used and safe therapy in inflammatory bowel disease, particularly in ulcerative colitis (UC), making it a promising candidate for enhanced efficacy by combining it with additional immunomodulatory medications. In this study, we studied the impact of vedolizumab monotreatment vs vedolizumab coadministration with other immunomodulatory drugs on intestinal inflammation and intestinal immune cells in vivo. METHODS Colon tissue from human patients with UC with active disease or in remission with or without vedolizumab treatment was stained by immunohistochemistry. We reconstituted NOD-SCID-SGM3 mice with human CD34+ cells and treated them with dextran sodium sulfate to induce acute colitis. Mice were treated with vedolizumab alone, or in combination with tacrolimus, ozanimid, or tofacitinib. RESULTS Vedolizumab reduced the number of CD3+ T cells and CD68+ monocytes/macrophages in the colon of patients with UC with active disease. Vedolizumab moderately decreased immune cell numbers in acute dextran sodium sulfate-induced colitis. The combination of vedolizumab with tacrolimus further reduced the number of infiltrating CD3+ T cells and CD68+ monocytes/macrophages and was superior in ameliorating intestinal inflammation when compared to vedolizumab monotreatment. In contrast, cotreatment using vedolizumab with ozanimod or tofacitinib had no additive effect. CONCLUSIONS Our data show that vedolizumab reduces the number of innate and adaptive immune cells in the mucosa of patients with UC. Further, the combination of vedolizumab with tacrolimus was more efficient to reduce immune cell numbers and to increase therapeutic efficacy than vedolizumab monotreatment. This finding indicates that combination treatment using these two drugs may be beneficial for patients who do not respond to vedolizumab monotherapy.

Abstract
The epithelial barrier forms the interface between luminal microbes and the host immune system and is the first site of exposure to many of the environmental factors that trigger disease activity in chronic inflammatory bowel disease (IBD). Disruption of the epithelial barrier, in the form of increased intestinal permeability, is a feature of IBD and other inflammatory diseases, including celiac disease and type 1 diabetes. Variants in genes that regulate or belong to the JAK-STAT signaling pathway are associated with IBD risk. Inhibitors of the JAK-STAT pathway are now effective therapeutic options in IBD. This review will discuss emerging evidence that JAK inhibitors can be used to improve defects in intestinal permeability and how this plays a key role in resolving intestinal inflammation.

Abstract
The incidence of ulcerative colitis (UC) in elderly patients is increasing. Elderly UC patients are likely to exhibit distinct features both at diagnosis and during follow-up. Age-related problems, including complications, immune dysfunction, and multidrug use, make the diagnosis and treatment of elderly UC more challenging. Suboptimal treatment considering adverse events leads to poor clinical outcome in elderly UC patients. Here, we reviewed the epidemiology, clinical presentation, medical therapy, colorectal cancer surveillance of UC in elderly patients.

Abstract
The recognition of the role of complement and Janus kinase (JAK)-dependent cytokines in the pathogenesis of inflammatory and immune-mediated disorders has revolutionized the treatment of a myriad of rheumatological and inflammatory diseases. C5 inhibitors and Janus kinase inhibitors have emerged as attractive therapeutic options. Because of the blockage of immune pathways, these targeted therapies carry an increased risk of infection. This article reviews the mechanism of action and the approved and off-label indications of the agents with most clinical experience within this drug classes. It discusses the associated risks of infection, proposing screening, prevention, and risk mitigation strategies.

Abstract
Poor translatability of animal disease models has hampered the development of new inflammatory bowel disorder (IBD) therapeutics. We describe a preclinical, ex vivo system using freshly obtained and well-characterized human colorectal tissue from patients with ulcerative colitis (UC) and healthy control (HC) participants to test potential therapeutics for efficacy and target engagement, using the JAK/STAT inhibitor tofacitinib (TOFA) as a model therapeutic. Colorectal biopsies from HC participants and patients with UC were cultured and stimulated with multiple mitogens ± TOFA. Soluble biomarkers were detected using a 29-analyte multiplex ELISA. Target engagement in CD3+CD4+ and CD3+CD8+ T-cells was determined by flow cytometry in peripheral blood mononuclear cells (PBMCs) and isolated mucosal mononuclear cells (MMCs) following the activation of STAT1/3 phosphorylation. Data were analyzed using linear mixed-effects modeling, t test, and analysis of variance. Biomarker selection was performed using penalized and Bayesian logistic regression modeling, with results visualized using uniform manifold approximation and projection. Under baseline conditions, 27 of 29 biomarkers from patients with UC were increased versus HC participants. Explant stimulation increased biomarker release magnitude, expanding the dynamic range for efficacy and target engagement studies. Logistic regression analyses identified the most representative UC baseline and stimulated biomarkers. TOFA inhibited biomarkers dependent on JAK/STAT signaling. STAT1/3 phosphorylation in T-cells revealed compartmental differences between PBMCs and MMCs. Immunogen stimulation increases biomarker release in similar patterns for HC participants and patients with UC, while enhancing the dynamic range for pharmacological effects. This work demonstrates the power of ex vivo human colorectal tissue as preclinical tools for evaluating target engagement and downstream effects of new IBD therapeutic agents.NEW & NOTEWORTHY Using colorectal biopsy material from healthy volunteers and patients with clinically defined IBD supports translational research by informing the evaluation of therapeutic efficacy and target engagement for the development of new therapeutic entities. Combining experimental readouts from intact and dissociated tissue enhances our understanding of the tissue-resident immune system that contribute to disease pathology. Bayesian logistic regression modeling is an effective tool for predicting ex vivo explant biomarker release patterns.

Abstract
BACKGROUND Inflammatory bowel diseases (IBD), including Crohn disease (CD) and ulcerative colitis (UC), are complex disorders with multiple comorbidities. We conducted international patient and physician surveys to evaluate current experiences and perceptions of patients with CD or UC and physicians who treat IBD. METHODS The IBD Global Assessment of Patient and Physician Unmet Need Surveys comprised a patient survey and a physician survey, fielded in North America and Europe between August 16, 2019, and November 10, 2019. Adults with CD or UC (targeted 1:1 ratio) were recruited from physicians, patient advocacy groups, and recruitment panels; physicians were recruited by recruitment agencies and panels. RESULTS In total, 2398 patients with IBD (1368 CD, 1030 UC) and 654 physicians completed surveys. Anxiety and depression were the most common comorbidities among patients with IBD. Patients and physicians were generally aligned on treatment goals and patient-physician communication. Patients with IBD reported high quality-of-life impact by rectal urgency and need to use the toilet, which were rated as lower-impact by physicians. Patients defined remission based on symptoms; physicians defined remission based primarily on clinical tests. Patients expected current treatments to control their disease for a longer duration than did physicians. Patients expressed more concern about corticosteroid use compared with physicians; many physicians reported prescribing corticosteroids for more than 4 months per year in some patients. CONCLUSIONS Patients could benefit from education about disease remission and expectations for current therapies. High corticosteroid use is concerning to patients, and physicians should minimize the use of corticosteroids for extended periods of time.

Abstract
BACKGROUND AND AIMS This 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]. METHODS Patients 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. RESULTS Of 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. CONCLUSIONS There 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.

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
Previously, the natural history of Crohn's disease and ulcerative colitis included significant morbidity due to limited treatment options that were not without serious side effects. Early treatment options included corticosteroids as well as mesalamine, thiopurines, and methotrexate. In 1998, monoclonal antibodies to a key inflammatory cytokine, TNFα, became available. Over the next 22 years, the field of gastroenterology has seen multiple new treatments emerging for inflammatory bowel disease (IBD) that target different aspects of the inflammatory cascade, significantly changing the therapeutic landscape. Additional monoclonal antibodies are available that target the integrins, which are adhesion proteins that traffic inflammatory leukocytes. Small molecule inhibitors block the inflammatory signals of several cytokines. New therapies that modulate lymphocyte escape from lymphoid tissue are promising. Lastly, stem cell technology has emerged as a platform to successfully treat perianal fistulizing disease. Our aim is to summarize the currently available therapies for IBD beyond steroids, mesalamine, and immune modulators. We highlight the most important clinical trials that have brought these treatments to clinical practice, and we discuss the ongoing clinical trials of novel therapies that have a high probability of eventual regulatory approval.

Pharmacokinetics and Bioequivalence of 2 Immediate-Release Tofacitinib Tablet Formulations in Chinese Healthy Volunteers Under Fasting and Fed Conditions. Clin Pharmacol Drug Dev 2020; 10:535-541. [PMID: 32770665 DOI: 10.1002/cpdd.864] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Accepted: 07/21/2020] [Indexed: 11/07/2022]
Abstract
The purpose of this study was to evaluate the bioequivalence of a generic immediate-release tofacitinib tablet versus a brand-named immediate-release tofacitinib tablet under fasting and fed conditions, and the food effect on pharmacokinetic profiles of the both formulations. This randomized, open-label, 2-period, crossover, bioequivalence study included 52 healthy Chinese subjects (fasting cohort: n = 26; fed cohort: n = 26). The subjects were assigned to receive a single 5-mg dose of generic or brand-named tofacitinib. Blood samples were collected at predosing and up to 14 hours after dosing. Tofacitinib concentrations in plasma were analyzed by high-performance liquid chromatography-tandem mass spectrometry. Safety was monitored. There were no significant differences in maximum plasma concentration, area under the plasma concentration-time curve from time zero to time t (AUC0-t ), AUC from time zero to infinity (AUC0-∞ ), and terminal elimination half-life between the test and reference formulations (all P > .05); high-fat food had no significant effect on AUC0-t , AUC0-∞, or terminal elimination half-life of immediate-release tofacitinib tablets (all P > .05). The 90% confidence intervals of the test/reference ratios of log-transformed maximum plasma concentration, AUC0-t , and AUC0-∞ were within the range of 80% to 125% under both fasting and fed conditions. No serious adverse events were reported. The 2 formulations of immediate-release tofacitinib tablets are bioequivalent and well tolerated under both fasting and fed conditions in healthy Chinese volunteers. Food had no clinically relevant effects on drug exposure of tofacitinib.

Abstract
Inhibition of Janus kinases [JAKs] in Crohn's disease [CD] patients has shown conflicting results in clinical trials. Tofacitinib, a pan-JAK inhibitor, showed efficacy in ulcerative colitis [UC] and has been approved for the treatment of patients with moderate to severe UC. In contrast, studies in CD patients were disappointing and the primary end point of clinical remission could not be met in the respective phase II induction and maintenance trials. Subsequently, the clinical development of tofacitinib was discontinued in CD. In contrast, efficacy of filgotinib, a selective JAK1 inhibitor, in CD patients was demonstrated in the randomized, double-blinded, placebo-controlled phase II FITZROY study. Upadacitinib also showed promising results in a phase II trial in moderate to severe CD. Subsequently, phase III programmes in CD have been initiated for both substances, which are still ongoing. Several newer molecules of this class of orally administrated immunosuppressants are being tested in clinical programmes. The concern of side effects of systemic JAK inhibition is addressed by either exclusively intestinal action or higher selectivity [Tyk2 inhibitors]. In general, JAK inhibitors constitute a new promising class of drugs for the treatment of CD.

Abstract
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.

Abstract
Background:
Inflammatory bowel disease, including both Crohn’s disease and ulcerative colitis, are two
chronic and progressive disorders affecting the gastrointestinal tract. Research on the molecular mechanisms of both
diseases has led to the introduction of targeted therapies which are able to selectively block the key inflammatory
mediators.
Methods:
Here, we discuss the current evidence about the mechanism of action with an up to date review of the
efficacy and safety of Janus kinase inhibitors in inflammatory bowel disease.
Results:
Multiple small molecule drugs have been evaluated for their use in both ulcerative colitis and Crohn’s
disease. Janus kinase inhibitors represent the most important family of these drugs, as their particular mechanism of
action enables a simultaneous and effective blockade of multiple cytokines involved in the pathogenesis of the
disease.
Conclusion:
Janus kinase inhibitors represent a promising therapeutic strategy, especially in ulcerative colitis. More
data are still necessary regarding its efficacy and safety in clinical practice.

Abstract
Inflammatory bowel disease (IBD) is a chronic and life-long disease characterized by gastrointestinal tract inflammation. It is caused by the interplay of the host's genetic predisposition and immune responses, and various environmental factors. Despite many treatment options, there is no cure for IBD. The increasing incidence and prevalence of IBD and lack of effective long-term treatment options have resulted in a substantial economic burden to the healthcare system worldwide. Biologics targeting inflammatory cytokines initiated a shift from symptomatic control towards objective treatment goals such as mucosal healing. There are seven monoclonal antibody therapies excluding their biosimilars approved by the US Food and Drug Administration for induction and maintenance of clinical remission in IBD. Adverse side effects associated with almost all currently available drugs, especially biologics, is the main challenge in IBD management. Natural products have significant potential as therapeutic agents with an increasing role in health care. Given that natural products display great structural diversity and are relatively easy to modify chemically, they represent ideal scaffolds upon which to generate novel therapeutics. This review focuses on the pathology, currently available treatment options for IBD and associated challenges, and the roles played by natural products in health care. It discusses these natural products within the current biodiscovery research agenda, including the applications of drug discovery techniques and the search for next-generation drugs to treat a plethora of inflammatory diseases, with a major focus on IBD.
