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

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

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

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?

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?

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.”

CCFA 2023 (Atlanta) Part 3

This is third day summarizing some of the talks at the regional CCFA conference. Erin Forster presented on Treatment with Oral Advanced Therapy. Below are my notes and some of the slides; my notes may have errors of omission or transcription. Can get access to full slide set: (n=22) here: Treatment with Oral Advanced Therapy

  • JAK inhibitors (Tofacitinib, Upadacitinib) have rapid onset of action and are taken orally
  • Tofacitinib (Xeljanz) -concern about cardiovascular events was derived from elderly rheumatologic patients.  Cardiovascular events are rare. Higher dose (TID) (in the hospital) associated with lower colectomy rates in acute severe ulcerative colitis.
  • Upadacitinib (Rinvoq) -now approved for CD and UC. Higher dosing could affect liver function (especially if underlying liver disease).  Also, JAK inhibitors as a class have similar safety concerns: increased herpes zoster and concerns for cardiovascular concerns (esp if >50 years)..
  • S!P receptor modulators: Oznaimod, Etrasimod & Amiselimod. Can cause bradycardia -have to check EKG prior.
  • None of the oral agents are safe in pregnancy

IBD Updates: Treat-to-Target Uptake, Long-Term Data on Ustekinumab Intensification, and Low Rates of C diff with Tofacitinib (& Clinical Pearl)

JL Yang et al. Inflamm Bowel Dis 2023; 29: 735-743. Utilization of Colonoscopy Following Treatment Initiation in U.S. Commercially Insured Patients With Inflammatory Bowel Disease, 2013-2019

In this study with 39,734 commercially-insured initiators of IBD medications (18-64 year old), 34% had a colonoscopy by 12 months and 42% at 15 months. The authors state that “it is evident that patients without any colonoscopy during this interval are not being followed under an optimal long-term T2T (treat-to-target) paradigm.”

RS Dalal et al. Inflamm Bowel Dis 2023; 29: 830-833. Long-Term Outcomes After Ustekinumab Dose Intensification for Inflammatory Bowel Diseases

This retrospective study examined 123 patients with Crohn’s disease and 40 with ulcerative colitis who had dose intensification with ustekinumab (to either every 4 weeks, n=91, or every 6 weeks, n=72). Dose escalation was effective in both achieving and maintaining corticosteroid-free clinical remission for 61% of patients with Crohn’s disease and 40% with ulcerative colitis at 24 months; endoscopic remission was noted in 43% with Crohn’s disease and 55% with ulcerative colitis.

EV Loftus et al. Inflamm Bowel Dis 2023; 29: 744-751. Open Access! Clostridium difficile Infection in Patients with Ulcerative Colitis Treated with Tofacitinib in the Ulcerative Colitis Program 

Using data from multiple studies with 1157 patients, only 9 tofacitinib patients developed Clostridioides difficile infection (CDI) which was lower than the placebo group. CDI were all mild–moderate in severity and resolved with treatment in 8 patients. Six of 9 patients continued tofacitinib treatment without interruption. The low rate of infection was likely in part due to screening for CDI prior to treatment. In addition, “it is possible than the lower rates of CDI …may be due to better-controlled disease…, thus reducing susceptibility to infection.”

One clinical pearl in the discussion: “When considering treatment [for CDI], initial therapy with oral vancomycin should be considered instead of metronidazole, and treating for at least 21 days should also be considered [in patients with IBD due to]…lower rates of CDI recurrence.”

Lipid Changes with IBD Medications

JAM Sleutjes et al. Inflamm Bowel Dis 2023; 29: 531-538. Open Access! Lipid Changes After Induction Therapy in Patients with Inflammatory Bowel Disease: Effect of Different Drug Classes and Inflammation

In this prospective study (n=198), the authors examined lipid profile changes at week 10 in patients starting IBD medications: corticosteroids, thiopurines, methotrexate, anti-TNF-α agents, vedolizumab, ustekinumab, and tofacitinib.

Key findings:

  • Relative increases in total cholesterol, HDL-c, and LDL-c were significant after prednisone (+26%, +31%, +12%) and tofacitinib therapy (+20%, +25%, +26%), respectively
  • No changes were observed in other drug classes
  • Findings did not correlate with calprotectin or CRP values, likely indicating a direct medication effect

My take: Recent studies have provided some reassurance regarding tofacitinib and the risk of major adverse cardiovascular events (MACEs) (see posts below). Nevertheless, it seems prudent to monitor lipids in patients receiving JAK inhibitors.

Tofacitinib Outperformed Vedolizumab in Anti-TNF-experienced Ulcerative Colitis

T Straamijer et al. Clin Gastroenterol Hepatol 2023; 21: 182-191. Open Access! Superior Effectiveness of Tofacitinib Compared to Vedolizumab in Anti-TNF-experienced Ulcerative Colitis Patients: A Nationwide Dutch Registry Study

Methods: Adults with ulcerative colitis (UC) previously who failed anti-TNF treatment and initiated vedolizumab (n=83) or tofacitinib (n=65) treatment were identified in the Initiative on Crohn and Colitis Registry in the Netherlands.

Key findings (Vedolizumab is in gray):

  • There was no difference in infection rate or severe adverse events.

My take: Coupled with more recent reassuring safety data on JAK inhibitors, this study makes a strong case for positioning Tofacitinib (or other JAK inhibitor) earlier in patients with moderate-to-severe ulcerative colitis. Given that vedolizumab outperformed adalimumab in a head-to-head study, this indicates that tofacitinib is a very effective therapy.
