Abstract
Background: Both vedolizumab and ustekinumab can be considered for the treatment of ulcerative colitis [UC], but head-to-head trials are lacking.
Aim: We aimed to compare the effectiveness of vedolizumab and ustekinumab after anti-tumour necrosis factor [anti-TNF] failure in UC patients.
Patients and methods: In this multicentre study, we included consecutive adult patients with UC, with partial Mayo score >2 and prior anti-TNF exposure, treated with vedolizumab or ustekinumab between January 2019 and August 2022. Comparisons were performed using propensity score analyses [inverse probability of treatment weighting].
Results: Among a total of 293 patients included, 151 and 142 received vedolizumab and ustekinumab, respectively. After propensity score analysis, steroid-free clinical remission [SFCR] [partial Mayo score ≤2] was achieved at week 16 in 38.0% and 40.3% of patients treated with vedolizumab and ustekinumab, respectively (adjusted odds ratio [aOR] = 1.11, 95% confidence interval [0.39-3.13], p = 0.85). Rates of SFCR in patients exposed to one, two, and three lines of biologics/small molecules among patients treated with vedolizumab and ustekinumab were respectively 53.3% vs 62.1% [p = 0.52], 44.4% vs 33.8% [p = 0.52], and 2.6% vs 19.1% [p = 0.027]. Endoscopic remission [SFCR and endoscopic Mayo score ≤1] and histological remission [SFCR, endoscopic remission, and Nancy histological index ≤1] at week 16 were achieved in respectively 5.3% vs 17.5% (aOR = 3.77 [1.25-11.36], p = 0.018) and 2.1% vs 11.1% (aOR = 5.85 [1.47-23.30], p = 0.012) in the vedolizumab and ustekinumab groups. No difference regarding the risk of drug discontinuation between the two groups (aHR = 1.03 [0.51-2.08], p = 0.92) was observed. While no factor was identified for vedolizumab, primary failure to at least one biologic/small molecule (OR = 0.31 [0.11-0.82], p = 0.018) was significantly associated with a decreased rate of SFCR among patients treated with ustekinumab.
Conclusion: While no difference in terms of short-term clinical remission was observed, ustekinumab appears to be more effective than vedolizumab in inducing endoscopic and histological remission at week 16 after failure of anti-TNFs in UC.
