Real-world comparison of effectiveness between tofacitinib and vedolizumab in patients with ulcerative colitis exposed to at least one anti-TNF agent

Beyond the Gut: A Systematic Review and Meta-analysis of Advanced Therapies for Inflammatory Bowel Disease-associated Extraintestinal Manifestations

BACKGROUND AND AIMS

Extraintestinal manifestations are frequent in patients with inflammatory bowel disease and have a negative impact on quality of life. Currently, however, there is no evidence available to determine which drug should be recommended for these patients beyond anti-tumour necrosis factor [anti-TNF] treatment. We aimed to analyse the frequency of new extraintestinal manifestations and the behaviour of pre-existing extraintestinal manifestations during advanced therapy.

METHODS

We conducted a systematic search on November 15, 2022, and enrolled randomized controlled trials, cohorts, and case series reporting the occurrence and behaviour of extraintestinal manifestations in patients with inflammatory bowel disease receiving advanced therapy [non-TNF inhibitor biologicals and JAK inhibitors]. Proportions of new, recurring, worsening, and improving extraintestinal manifestations were calculated with 95% confidence intervals [CIs]. The risk of bias was assessed with the QUIPS tool.

RESULTS

Altogether, 61 studies comprising 13,806 patients reported eligible data on extraintestinal manifestations. The overall proportion of new extraintestinal manifestations was 8% [95% CI, 6-12%] during advanced therapy. There was no significant difference between the frequency of new extraintestinal manifestations during vedolizumab and ustekinumab therapy [11%, 95% CI, 8-15% vs 6%, 95% CI, 3-11%, p = 0.166]. The improvement of pre-existing manifestations was comparable between vedolizumab- and ustekinumab-treated patients, except for joint involvement [42%, 95% CI, 32-53% vs 54%, 95% CI, 42-65%, p = 0.029].

CONCLUSION

The proportion of new extraintestinal manifestations was low during advanced therapy. Furthermore, the improvement of pre-existing manifestations was comparable between advanced therapies, except for pre-existing joint manifestations.

Real-world Evidence Comparing Tofacitinib and Vedolizumab in Anti-TNF-experienced Patients With Ulcerative Colitis

BACKGROUND

Antitumor necrosis factor (anti-TNF) inhibitors are first-line treatment among patients with ulcerative colitis (UC). With time, patients tend to lose response or become intolerant, necessitating switching to small cell biologics such as tofacitinib or vedolizumab. In this real-world study of a large, geographically diverse US population of TNF-experienced patients with UC, we evaluated the effectiveness and safety of newly initiating treatment with tofacitinib vs vedolizumab.

METHODS

We conducted a cohort study using secondary data from a large US insurer (Anthem, Inc.). Our cohort included patients with UC newly initiating treatment with tofacitinib or vedolizumab. Patients were required to have evidence of treatment with anti-TNF inhibitors in the 6 months prior to cohort entry. The primary outcome was treatment persistence >52 weeks. Additionally, we evaluated the following secondary outcomes as additional measures of effectiveness and safety: (1) all-cause hospitalization; (2) total abdominal colectomy; (3) hospitalization for infection; (4) hospitalization for malignancy; (5) hospitalization for cardiac events; and (6) hospitalization for thromboembolic events. We used fine stratification by propensity scores to control for confounding by demographics, clinical factors, and treatment history at baseline.

RESULTS

Our primary cohort included 168 new users of tofacitinib and 568 new users of vedolizumab. Tofacitinib was associated with lower treatment persistence (adjusted risked ratio, 0.77; 95% CI, 0.60 -0.99). Differences in secondary measures of effectiveness or safety between tofacitinib initiators vs vedolizumab initiators were not statistically significant (all-cause hospitalization, adjusted hazard ratio, 1.23; 95% CI, 0.83-1.84; total abdominal colectomy, adjusted HR, 1.79; 95% CI, 0.93-3.44;and hospitalization for any infection, adjusted HR, 1.94; 95% CI, 0.83-4.52).

DISCUSSION

Ulcerative colitis patients with prior anti-TNF experience initiating tofacitinib demonstrated lower treatment persistence compared with those initiating vedolizumab. This finding is in contrast to other recent studies suggesting superior effectiveness of tofacitinib. Ultimately, head-to-head randomized, controlled trials that focus on directly measured end points may be needed to best inform clinical practice.

Histological healing induced by tofacitinib in ulcerative colitis: A multicentre study

BACKGROUND

While the efficacy of tofacitinib to induce and maintain clinical and endoscopic remission is well established in ulcerative colitis (UC), little is known about its efficacy to induce histological remission.

METHODS

We conducted a retrospective multicentric cohort study. UC patients ≥ 16 years treated by tofacitinib in whom histological activity has been evaluated before and after induction were eligible. The primary endpoint was the histological remission at the end of induction, assessed by the Nancy index and the epithelial neutrophilic infiltrate.

RESULTS

A total of 42 patients with UC (93% previously exposed to an anti-TNF and 81% to vedolizumab) were included between July 2018 and April 2022 and were followed for a median duration of 84 weeks [IQR, 35-134]. At the end of induction period (whether prolonged or not), 19% and 24% of patients achieved histological remission, using the Nancy index and the epithelial neutrophilic infiltrate, respectively. Survival without tofacitinib discontinuation was significantly longer in patients without epithelial neutrophilic infiltrate at the end of induction (whether prolonged or not) compared with patients with epithelial neutrophilic infiltrate (p = 0.036).

CONCLUSION

Tofacitinib induced histological remission in one fifth to one quarter of patients with UC who have previously failed anti-TNF or/and vedolizumab after induction (whether prolonged or not).

Efficacy of biologic and small molecule agents as second-line therapy after exposure to TNF inhibitors in patients with ulcerative colitis: A propensity-matched cohort study

BACKGROUND

There is limited real-world data on comparative effectiveness of different biologic or small molecule agents as second-line therapies in patients with ulcerative colitis (UC) with prior exposure to a tumour necrosis factor inhibitor (TNFi).

METHODS

We conducted a retrospective cohort study using TriNetX, a multi-institutional database to assess the efficacy of tofacitinib, vedolizumab and ustekinumab in patients with ulcerative colitis (UC) with prior exposure to a TNFi. Failure of medical therapy was defined as a composite outcome of intravenous steroids or colectomy within 2 years. One-to-one propensity score matching was performed for demographics, disease extent, mean haemoglobin, C-reactive protein, albumin and calprotectin, prior IBD medications and steroid use between cohorts.

RESULTS

Among 2141 patients with UC and prior exposure to TNFi, 348 (16.2%), 716 (33.4%) and 1077 (50.3%) were switched to tofacitinib, ustekinumab and vedolizumab, respectively. After propensity-score matching, there was no difference in the composite outcome (aOR: 0.77, 95% CI: 0.55-0.1.07) but higher risk of colectomy (aOR: 2.69, 95% CI: 1.31-5.50) in the tofacitinib cohort than the vedolizumab cohort. There was no difference in the risk of composite outcome (aOR: 1.29, 95% CI: 0.89-1.86) but higher risk of colectomy (aOR: 2.63, 95% CI: 1.24-5.58) in the tofacitinib cohort than the ustekinumab cohort. The vedolizumab cohort had a higher risk of composite outcome (aOR: 1.67, 95% CI: 1.29-2.16) than the ustekinumab cohort.

CONCLUSION

Ustekinumab might be the preferred second-line therapy over tofacitinib and vedolizumab in patients with UC that were previously exposed to a TNFi.
