Background The development program (UNIFI) has shown promising results of ustekinumab in ulcerative colitis (UC) treatment that should be confirmed in clinical practice. Aims To evaluate the durability, effectiveness and safety of ustekinumab in UC in real-life. Methods Patients included in the prospectively maintained ENEIDA registry who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score (PMS) >2] were included. Clinical activity and effectiveness were defined based on PMS. Short-term response was assessed at week 16. Results A total of 95 patients were included. At week 16, 53% of patients had response (including 35% of patients in remission). In the multivariate analysis, elevated serum C-reactive protein was the only variable significantly associated with lower likelihood of achieving remission. Remission was achieved in 39% and 33% of patients at weeks 24 and 52, respectively. Thirty-six percent of patients discontinued the treatment with ustekinumab during a median follow-up of 31 weeks. The probability of maintaining ustekinumab treatment was 87% at week 16, 63% at week 56, and 59% at week 72; primary failure was the main reason for ustekinumab discontinuation. No variable was associated with risk of discontinuation. Three patients reported adverse events; one of them had a fatal severe SARS-CoV-2 infection. Conclusions Ustekinumab is effective both in the short and the long-term in real-life, even in a highly refractory cohort. Higher inflammatory burden at baseline correlated with lower probability of achieving remission. Safety was consistent with the known profile of ustekinumab.
Summary Background Data on the long‐term administration of ustekinumab in recommended doses are limited. Aim To assess the real‐world, long‐term effectiveness of ustekinumab in refractory Crohn's disease (CD). Methods Multi‐centre study of CD patients starting ustekinumab at the recommended dose, followed for 1 year. Values for the Harvey‐Bradshaw Index (HBI), endoscopic activity, C‐reactive protein (CRP), and faecal calprotectin (FC) were recorded at baseline and at weeks 26 and 52. Demographic and clinical data, previous treatments, adverse events (AEs) and hospitalisations were documented. Potential predictors of remission were examined. Results A total of 407 patients were analysed. The initial maintenance dose of 90 mg SC was administered every 12, 8 and 4 weeks in 56 (14%), 347 (85%) and 4 (1%) patients, respectively. After 52 weeks, treatment was discontinued in 112 patients (27.5%). At baseline, 295 (72%) had an HBI >4 points. Of these, 169 (57%) and 190 (64%) achieved clinical remission at weeks 26 and 52, respectively. FC levels returned to normal in 44% and 54% of patients at weeks 26 and 52, and CRP returned to normal in 36% and 37% of patients at weeks 26 and 52, respectively. AEs were recorded in 60 patients. The use of fewer previous anti‐TNFα agents and ileal localisation were associated with clinical remission, and endoscopic severity was associated with poor response. No factors correlated with endoscopic remission. Conclusion After 52 weeks, ustekinumab demonstrated effectiveness in inducing clinical and endoscopic remission in patients with refractory CD.
More than 10% of Spanish IBD patients who are candidates for anti-TNF therapy have latent TB. TST retest is required to identify at least 14% of such patients; therefore, it should be considered if the initial TST is negative. ChP is safe in IBD patients even in those taking concomitant, potentially hepatotoxic drugs.
Background Ustekinumab has shown promising results in ulcerative colitis (UC) in the development program (UNIFI) that should be confirmed in clinical practice. Our aim was to evaluate the effectiveness and safety of ustekinumab in UC in real life. Methods Patients included in the prospectively maintained ENEIDA registry that received at least 1 dose of ustekinumab intravenously due to active UC were included. Clinical activity and effectiveness were defined based on Partial Mayo Score (PMS). The short-term response was assessed at week 8 and 16. The last-observation-carried-forward method was used in patients that stopped ustekinumab treatment before week 8 or 16. Variables associated with short-term remission were identified by logistic regression analysis. Data quality was assessed by remote monitoring. Results Forty-seven patients were included (Table 1); all of them had been previously exposed to biologic agents (70% to >2): 100% to anti-TNF and 83% to vedolizumab. A total of 26% had been exposed to tofacitinib. Seventeen patients (36%) had response at week 8 [3 of them (6%) had remission]; 16 patients (34%) had response at week 16 [5 of them (11%) had remission] (Figure 1). There was a statistically significant decrease in C-reactive protein (CRP) concentration during the induction only in patients with a response at week 16 (Figure 2). The proportion of patients with CRP elevated at baseline and at week 8 was higher among non-responders at week 16 (Table 2). In the multivariate analysis, higher PMS at week 8 [odds ratio (OR) = 0.5; 95% confidence interval (CI) = 0.3–0.9)] and CRP over the upper normal limit at week 8 (OR = 0.1; 95% CI = 0.01–0.8) were associated with lower probability of response at week 16; steroids during induction increased the probability of response at week 16 (OR = 8; 95% CI = 1–71). Of patients without response at week 8, only 7% achieved response at week 16. Seventeen out of 31 patients continued ustekinumab beyond week 16, despite being non-responders. Of these 17 patients, 4 reached remission after the third dose, 1 after the fifth and 1 after the seventh one. There were 2 infections, one of them with fatal consequences (in a patient under steroids and tacrolimus due to renal transplant). Conclusion Ustekinumab shows benefit in some UC patients in real practice, even in a very refractory cohort in which the drug was prescribed as last resort. Patient status at week 8 seems to be a good predictor of response after the induction. Safety was consistent with the known profile of ustekinumab.
