Visser E, Reijntjes M, Heuthorst L et al.The Lancet Gastroenterology & Hepatology, 2026; 11, 190-203. Appendicectomy versus switching to a JAK inhibitor in inducing remission in patients with active ulcerative colitis after biologic therapy failure (COSTA): 1-year results of a multicentre, prospective, cohort study

Last year, the ACCURE Trial (see blog post link below), showed that laparoscopic appendicectomy, in addition to standard medical therapy, significantly reduced the relapse rates for ulcerative colitis (UC) within 1 year. Most patients were treated with mesalamine.

The COSTA study examined adult patients (n=125) who were not responding to advanced therapy. Patients were offered one of three treatments: laparoscopic appendicectomy while continuing their existing advanced therapy at a stable dose; switching their advanced therapy to a JAK inhibitor; or colectomy. 116 patients were included in the modified intention-to-treat-analysis (67 received appendicectomy and 49 received JAK inhibitor (primarily tofacitinib).

Key findings:

  • 22 (32.8%) of 67 patients in the appendicectomy group were in clinical remission without therapy failure at 12 months compared with six (12.2%) of 49 patients in the JAK inhibitor group (p=0.016)
  • At 12 months, corticosteroid-free clinical remission without therapy failure was attained in 22 (32.8%) of 67 patients in the appendicectomy group compared with six (12.2%) of 49 patients in the JAK inhibitor group  (p=0.010). Clinical response in 49 (73.1%) of 67 patients compared with 26 (53.1%) of 49 patients (p=0·025), and endoscopic response in 31 (48.4%) of 64 patients compared with 11 (25.6%) of 43 patients (p=0·018)

My take (borrowed in part from the authors): “Appendicectomy as an adjunct to advanced therapy in biologic-exposed patients with active ulcerative colitis was associated with higher clinical remission rates at 12 months compared with switching to a JAK inhibitor.” We don’t know how appendectomy would influence disease course in pediatric patients. We also don’t know how this information will be incorporated into adult guidelines.

Interestingly, there have been studies (two cited below) indicating that appendectomy lowers the risk of developing inflammatory bowel disease:

    Comparative Safety of Janus Kinase Inhibitors vs Tumor Necrosis Factor Antagonists For Inflammatory Bowel Disease Patients

    Posted on by

    D Ahuja et al. Clin Gastroenterol Hepatol 2026. 24: 794-804. Comparative Safety of Janus Kinase Inhibitors vs Tumor Necrosis Factor Antagonists in Patients With Inflammatory Bowel Diseases

    Methods: This retrospective cohort study used an administrative claims database and identified patients with IBD who were new users of either JAK inhibitors (n=856) or TNF antagonists (n=9422) between 2016 and 2023. Mean age was 45 years.

    Key findings:

    • There was no difference in the risk of VTE (1.3 vs 1.2; HR, 0.66; 95% CI, 0.28–1.57) and MACE (0.4 vs 0.7; HR, 0.50; 95% CI, 0.19–1.30)
    • There was no difference in the risk of serious infections (4.9 vs 5.4; HR, 0.97); however, JAK inhibitors were associated with an increase risk of overall infections (incidence rate, 62.4 per 100 person-years [PY] vs 37.4 per 100 PY; hazard ratio [HR], 1.60)

    The authors note that their findings differ from the ORAL study (Ytterberg et al. NEJM 2022; 386: 316-326.) which showed higher risk of MACE in patients receiving tofacitinib. In the current study, even in patients deemed to be at higher risk for MACE (age >50 years with at least 1 cardiovascular risk factor), JAK inhibitors were associated with lower incidence and risk of MACE compared with TNF antagonists (IR per 1000 PY, 0.4 vs 2.1, HR 0.10).

    My take (borrowed from the authors) “It is unlikely that JAK inhibitors are associated with higher risk of VTE and MACE compared with TNF antagonists in most patients with IBD.”

    “Real-World” Experience: High Dose Upadacitinib Recaptures IBD Response

    Posted on by

    AHY Ho et al. Clin Gastroenterol Hepatol 2026; 24: 763-771. Real-world Experience of Upadacitinib Reinduction and High-dose Maintenance Therapy in Inflammatory Bowel Disease

    Methods: This was a prospective cohort study of patients (n=181 — 79 CD, 83 UC, 6 -IBD-U, 13 with IPAA) treated with UPA between April 2022 and November 2023. Included patients responded to UPA induction, had loss of response (LOR) after dose reduction, and subsequently received reinduction therapy with 45 mg QD. They were followed for a median duration 93 weeks.

    Key findings:

    • Dose escalation to 45 mg QD for a median of 13 weeks (IQR, 8–36 weeks) recaptured clinical response in 80.4%
    • Among patients who recaptured response, 19 again reduced dose
    • 93.8% of patients on 45 mg QD maintained remission vs 21.1% who again dropped to 30 mg QD (P < .001)
    • Acne/rosacea was the most common adverse event (39%); there were no serious adverse events

    In their discussion, the authors note that dose escalation with another JAK inhibitor, tofacitinib, also has been shown to reverse LOR (in about 50%). In addition, they note that “in our experience, prolonged exposure to 45 mg QDD UPA is safe.” Though, “a longer follow-up period…is required to address long-term safety of UPA in IBD, especially at a higher dose.”

    My take: Many patients taking UPA have not responded to multiple other advanced therapy. As such, the potential to recapture response with a higher dose of UPA is an important finding. Dose intensification is an effective strategy for most of the advanced therapies.

    Briefly noted: S Honap et al. Clin Gastroenterol Hepatol 2026; 24: 784-793. Open Access! Comparative Effectiveness of Tofacitinib vs Upadacitinib for the Treatment of Acute Severe Ulcerative Colitis In this retrospective study of 111 adults with ASUC, Between days 3 and 7 after treatment initiation, upadacitinib was associated with greater response rates (84% vs 54%), but response/remission was comparable at day 98 (45%/36% vs 55%/48%) and day
    182 (29/29% vs 39/34%).

    Postoperative Outcomes with Tofacitinib Following Colectomy for ASUC and Real-World Outcomes for Upadacitinib in Crohn’s Disease

    Posted on by

    C Larson et al. Clin Gastroenterol Hepatol 2025; 23: 2263-2271. Postoperative Outcomes in Tofacitinib-Treated Patients With Acute Severe Ulcerative Colitis Undergoing Colectomy

    This  was a multicenter, retrospective, case-control study of patients hospitalized with ASUC who underwent colectomy, comparing patients treated with tofacitinib (n=41) prior to colectomy with infliximab-treated controls (n=68).

    Key findings:

    • Compared with tofacitinib-treated patients, infliximab-treated patients had higher overall rates of overall (44 [64.7%] vs 13 [31.7%]; P = .002) and serious (19 [27.9%] vs 3 [12%]; P = .019) postoperative complications

    My take: This study supports the safety of JAK inhibitor therapy for ASUC. It showed a significantly lower rate of overall postoperative complications in ASUC patients treated with tofacitinib compared with infliximab; the authors note that “these findings can likely be extrapolated to upadacitinib, a selective JAK inhibitor, given its similar mechanism of action.”

    Prior Exposure to TNF Antagonists May Increase Response to JAK Inhibitors in Patients with Ulcerative Colitis

    Posted on by

    HH Lee et al. Clinical Gastroenterology and Hepatology 2025; 23, 2102 – 2114. Open Access! Differential Efficacy of Advanced Therapies in Inducing Remission in Ulcerative Colitis Based on Prior Exposure to TNF Antagonists

    Methods: Meta-analysis of 17 randomized controlled trials in 8871 adults with moderate-severe UC. The authors calculated the ratio of odds ratio of achieving remission with active drug vs placebo, in TNF antagonist–naïve vs TNF antagonist–exposed patients.

    Key findings:

    • JAK inhibitors: Less efficacious in TNF antagonist–naïve vs exposed patients (6 trials; ratio of OR, 0.47)
    • IL-23 antagonists: No significant difference was observed in efficacy of selective interleukin-23 antagonists vs placebo in TNF antagonist–naïve vs exposed patients (6 trials; ratio of OR, 1.07)
    • Lymphocyte trafficking inhibitors: More efficacious in TNF antagonist–naïve vs exposed patients (5 trials; odds ratio [OR], 1.88)

    Discussion:

    • This study “confirmed prior observations that exposure to TNF antagonists significantly reduces the efficacy of lymphocyte trafficking inhibitors in inducing remission, including both vedolizumab and S1P receptor modulators, by approximately 50%.In contrast, prior exposure to TNF antagonists was associated with a significant increase in the efficacy of JAK inhibitors in inducing remission, with 2-fold higher efficacy in TNF antagonist–exposed vs TNF antagonist–naïve patients”
    • In the SELECT-COMPARE trial in patients with rheumatoid arthritis, there was also an improved response to upadacitinib in patients with prior adalimumab.
    • “The current findings raise the intriguing possibility that exposure to TNF antagonists could result in lasting effects on the immune system that differentially alter responsiveness to therapies with distinct mechanisms of action”

    My take: This study suggests that JAK inhibitors are a good choice for secondary therapy after anti-TNF agents. Other factors, besides efficacy, including safety, extraintestinal manifestations, and cost, have to be considered as well.

    JAKne: JAK inhibitor–induced acne

    Posted on by

    S Honap et al. Clinical Gastroenterology and Hepatology 2025 (EPUB). Open Access! Janus Kinase (JAK) Inhibitor-Induced Acne in Inflammatory Bowel Disease: An International, Multicenter, Retrospective Cohort Study

    Mehtods: This international, multicenter, retrospective cohort study consecutively enrolled JAK-inhibitor-treated patients with IBD who subsequently developed acne (aka JAKne).

    Key findings:

    • Among 2183 JAK inhibitor–treated patients with IBD, 272 developed acne
    • 70% of acne cases occurred within the first 3 months of treatment initiation
    • The crude prevalence rates of acne were 15.9% for upadacitinib, 4.3% for tofacitinib, and 1.9% for filgotinib, with dose-dependent relationships observed for upadacitinib and tofacitinib
    • Most cases were mild-moderate in severity. Mild (<10% of body surface area) was noted in 68%, Moderate (10-30% of BSA) was noted in 24%, and Severe (>30% of BSA) was note in 8%
    • Among those who developed acne, areas that were affected included the face in 89%, the back in 33%, the chest in 27% and the scalp in 1%
    • 40% received pharmacologic intervention
    • 18% of patients who developed acne had JAK inhibitor dose reduction or discontinuation

    My take: JAKne is a common adverse effect.  Early identification, proactive counseling, and timely interventions, such as dose reduction, acne therapies or referral to dermatology, are crucial in managing this side effect.

    Managing Drug-Induced Acne in IBD: A Guide for Gastroenterologists

    Posted on by

    MJ Temido et al. Am J Gastroenterol 2025;120:125–134. Drug-Induced Acne in Inflammatory Bowel Disease: A Practical Guide for the Gastroenterologist

    “Corticosteroids and Janus kinase inhibitors (JAKi) are commonly used for the treatment of inflammatory bowel disease (IBD) and are known to aggravate a prior tendency to acne or trigger the development of new acneiform eruptions. Both randomized controlled trials and real-world studies have identified acne as one of the most common treatment-emergent adverse events in JAKi… This review examines the characteristics of drug-induced acne in IBD treatments, provides a practical guide for gastroenterologists to manage mild-to-moderate occurrences, and highlights when to seek specialist dermatology advice.”

    My take: This is a helpful review of acne management in the setting of IBD.

    Tofacitinib vs Ustekinumab -Which is Better for Ulcerative Colitis?

    Posted on by

    RS Dalal et al. Inflammatory Bowel Diseases, Volume 30, Issue 3, March 2024, Pages 395–401. 1-Year Comparative Effectiveness of Tofacitinib vs Ustekinumab for Patients With Ulcerative Colitis and Prior Antitumor Necrosis Factor Failure

    In this real-world cohort of anti-TNF-exposed patients with ulcerative colitis, tofacitinib (n=69) and ustekinumab (n=97) demonstrated similar effectiveness in achieving steroid-free clinical remission (SCFR) at 12 and 52 weeks. The median follow-up was 88.0 and 62.0 week, respectively. 35 of 66 in the tofacitinib cohort had dose reduction from the starting dose of 10 mg twice daily. This reduction occurred at a mean of 144 days. 59 of 97 in the ustekinumab cohort received either Q4W dosing (n=43) or Q6W (n=16).

    Key findings:

    • 53% of patients receiving tofacitinib and 32% of patients receiving ustekinumab achieved SFCR at 12 weeks. Tofacitinib-treated patients had higher baseline Mayo endoscopic subscores and CRPs.
    • At 52 weeks, approximately 50% of patients in both treatment groups achieved SFCR. There were also high proportions (>60%) of patients in both treatment groups who had endoscopic response within 52 weeks.
    • Both drugs were well-tolerated, as only 1 patient in each treatment group discontinued therapy due to an AE during >260 patient-years of follow-up.

    My take: This shows similar response to either tofacitinib and ustekinumab in a cohort that had refractory disease as patients were anti-TNF failures and most had prior vedolizumab as well.

    When is the Right Time to De-escalate Dose of Tofacitinib for Ulcerative Colitis?

    Posted on by

    A Yu et al. Clin Gastroenterol Hepatol 2023; 21: 3115-3124. Open Access! Real-World Experience With Tofacitinib Dose De-Escalation in Patients With Moderate and Severe Ulcerative Colitis

    On May 30, 2018, the US Food and Drug Administration (FDA) expanded the indication of tofacitinib (Xeljanz; Pfizer), an oral Janus kinase (JAK) inhibitor, for the treatment of adults with moderately to severely active ulcerative colitis. However, the optimal dosing remains unclear.

    In this “real-world” study by Yu et al, a retrospective review of 162 patients was conducted (2012-2022). 52% continued 10 mg twice daily while 48% underwent dose de-escalation to 5 mg twice daily.  The primary outcome was evidence of UC disease activity–related events: hospitalization/surgery, corticosteroid initiation, tofacitinib dose increase, or therapy switch.

    Key findings:

    • Cumulative incidence rates of UC events at 12 months were similar in patients with and without dose de-escalation (56% vs 58%; P = .81)
    • An induction course with 10 mg twice daily for more than 16 weeks was protective of UC events (hazard ratio [HR], 0.37) while ongoing severe disease (Mayo 3) was associated with UC events (HR, 6.41)
    • Twenty-nine percent of patients with UC events had their dose re-escalated to 10 mg twice daily, with only 63% able to recapture clinical response at 12 months

    Discussion Points:

    •  “Although the product label recommends dose de-escalation after 8 or 16 weeks, clinical practice is variable in the real-world setting… In this retrospective real-world study of moderate to severe UC patients with almost half undergoing dose de-escalation, we observed that more than half of patients experienced a UC disease activity–related event within 12 months after dose de-escalation, particularly in patients with an induction course of fewer than 16 weeks and active endoscopic disease at 6 months after induction…”
    • ” Although dose de-escalation is preferable for long-term maintenance therapy to reduce the potential lifetime risk of medication-related adverse events [eg. VTE], it must be balanced with sustained remission to prevent short- and long-term disease-related complications.”
    • “In the OCTAVE study which reported higher rates of long-term remission, patients de-escalated only after having shown clinical and endoscopic remission after 52 weeks on tofacitinib 10 mg twice daily”

    My take (borrowed from authors):  “Emphasis should be placed on clinical and endoscopic evidence of improvement before consideration of dose de-escalation to ensure the highest probability of treatment success.” This advice, though, may conflict with product labelling which states that “tofacitinib induction with 10 mg twice daily beyond 16 weeks is not recommended; in fact, it is recommended to stop after 16 weeks if adequate response has not been achieved.”
