Effectiveness and safety of ustekinumab in bio-naive Crohn's disease patients: a multicentre observational retrospective study.

ABSTRACT:

Background

Clinical trials have demonstrated the efficacy and safety of ustekinumab in Crohn's disease (CD). However, more data are necessary on the effectiveness of ustekinumab in bio-naïve patients in real-life studies.

Objectives

The aim of our study was to evaluate the effectiveness and safety of ustekinumab in patients with CD refractory or intolerant to conventional therapy and without previous exposure to biological drugs.

Design

We performed a nationwide, observational, retrospective, multicentre study including patients with CD, in which ustekinumab was used as the first biological drug.

Methods

The corticosteroid-free clinical and biological response and remission were analysed at weeks 16, 24, 52 and 72. Clinical remission was defined as Harvey-Bradshaw index ⩽ 4 and biological remission as a faecal calprotectin (FC) <250 mg/g and C-reactive protein (CRP) <5 mg/L. Moreover, the persistence of the treatment and any adverse events were assessed.

Results

In all, 84 patients were included in the study, males and females were equally distributed, with a median age of 63 years [interquartile range (IQR): 51-75] and a median disease duration of 6.8 years [IQR: 3.6-17.0]. The majority (86.9%) of patients were treated with ustekinumab as monotherapy, without concomitant immunosuppressive medication. The proportion of patients in corticosteroid-free clinical remission or response at weeks 16, 24, 52 and 72 was 93.3% (56/60), 86.8% (46/53), 82.2% (37/45) and 71.4% (30/42), respectively. CRP returned to normal values in 47.6%, 43.2%, 50% and 52.4% of patients at weeks 16, 24, 52 and 72, respectively. Similarly, FC was normalized in 45.5%, 45.5%, 48.6% and 50% of patients at weeks 16, 24, 52 and 72, respectively. The cumulative probability of remaining on ustekinumab treatment was 84.8% (95% confidence interval: 73.3-91.6) after 72 weeks. Ustekinumab was discontinued in 10 patients (11.9%) within 72 weeks of follow-up. Reasons for discontinuing treatment were lack of response (n = 4), adverse events (n = 4) and death (n = 2). There were no discontinuations because of stable remission.

Conclusions

Ustekinumab was effective and safe in Spanish bio-naïve CD patients, showing a quicker and more durable response than obtained in patients with previous biological treatment. In this cohort of bio-naïve patients starting on ustekinumab, the average age was high.

Plain language summary

Effectiveness and safety of ustekinumab in Crohn's disease patients not previously exposed to other biological therapies Evidence on the use of ustekinumab in biological naïve real-world patients is scarce. Here, we present real-world data evaluating the effectiveness and safety of ustekinumab in 84 bio-naïve patients from 17 Spanish hospitals. We report high rates of both clinical and biological remission. Moreover, after 1 year, 90.4% of patients remained being treated with ustekinumab. The safety profile of ustekinumab in these patient population was favourable. In conclusion, our results show that in patients with CD, ustekinumab could be considered as first-line therapy.

Project description:BackgroundThe effectiveness of ustekinumab in patients with refractory Crohn's disease (CD) has been investigated in several real-world studies. However, very few data concerning the real-life experience in Italy have been reported. Therefore, this study assessed the effectiveness of ustekinumab in a large cohort of Italian patients with refractory CD.MethodsAll patients who had started on ustekinumab after failure of or intolerance to antitumour necrosis factor-α (TNF-α) treatment at five tertiary centres between November 2018 and February 2020 were retrospectively enrolled. The coprimary outcome was corticosteroid-free clinical remission, defined as a Harvey-Bradshaw Index (HBI) score of ⩽4, at weeks 26 and 52. The secondary outcomes were changes in the HBI and C-reactive protein (CRP) values at weeks 8, 26, and 52 from baseline and the normalization of CRP in patients with initially abnormal values.ResultsTotally, 140 patients who had previously received at least one anti-TNF-α agent were enrolled; 40.0% received two anti-TNF-α agents and 20.0% received vedolizumab. At baseline, 108 patients (77.1%) had HBI scores of >4; of these, 56.5% and 58.3% achieved corticosteroid-free clinical remission at weeks 26 and 52, respectively. Significant decreases in HBI and CRP values were observed at weeks 8, 26, and 52 in the entire study cohort (all p < 0.0001). The CRP values were normalized in 34.9%, 37.8%, and 49.3% of the patients by weeks 8, 26, and 52, respectively. The baseline HBI score of ⩾8 was a negative predictor of corticosteroid-free clinical remission at week 52 (odds ratio: 0.21, 95% confidence interval: 0.08-0.56, p = 0.002). The probability of remaining on ustekinumab after 52 weeks was 92.1%. Eleven (7.9%) patients discontinued ustekinumab (three for adverse events).ConclusionOur study findings confirm the effectiveness and safety of ustekinumab in patients with CD after failure of or intolerance to anti-TNF-α therapy.

Project description:BackgroundUstekinumab and vedolizumab are both effective for treating Crohn's disease (CD). However, no head-to-head trials have been conducted thus far. We aimed to compare the effectiveness of ustekinumab and vedolizumab in CD patients either naïve or exposed to tumor necrosis factor-alpha inhibitors (TNFi).MethodsPatients treated with vedolizumab or ustekinumab for luminal CD were included from six centers in China from May 2020 to July 2023. Steroid-free remission, clinical remission, objective response, and remission at Weeks 26 and 52 were evaluated in a retrospective multicenter propensity score-weighted cohort.FindingsA total of 536 patients were included (386 ustekinumab, and 150 vedolizumab). After adjustment, ustekinumab showed higher rates of clinical remission (56.4% vs. 47.8%, P = 0.005), steroid-free remission (55.4% vs. 46.1%, P = 0.003), and objective response (67.8% vs. 42.7%, P < 0.001) than vedolizumab at Week 26. At Week 52, ustekinumab exhibited significantly higher rates of clinical remission (65.8% vs. 37.5%, P < 0.001), steroid-free remission (65.8% vs. 37.5%, P < 0.001), objective response (66.7% vs. 23.8%, P < 0.001), and objective remission (31.4% vs. 12.7%, P < 0.001). Subgroup analyses revealed that ustekinumab had higher rates of clinical remission, steroid-free remission, and objective response at Weeks 26 and 52, and objective remission at Week 52 in TNFi-exposed patients, while ustekinumab showed higher rates of objective response at Weeks 26 and 52 and clinical remission, steroid-free remission and objective remission at Week 52 in TNFi-naïve patients. Adverse event rates were similar between the groups (4.9% ustekinumab vs. 6.7% vedolizumab, P = 0.423).InterpretationUstekinumab showed superior clinical and objective outcomes compared to vedolizumab, with comparable safety outcomes. The therapeutic superiority was observed in both short-term and long-term phases in TNFi-exposed patients, and the long-term phase in TNFi-naïve patients.FundingNational Natural Science Foundation of China, Guangdong Basic and Applied Basic Research Foundation, Key Research Projects of the Sixth Affiliated Hospital, Sun Yat-sen University, the program of Guangdong Provincial Clinical Research Center for Digestive Diseases, and National Key Clinical Discipline.
