RESUMO

OBJECTIVE: Ustekinumab was recently approved for the treatment of moderate-to-severe ulcerative colitis (UC). Although data from the UNIFI clinical trial are encouraging, real-world data assessing effectiveness and safety are scarce. The aim of this study was to assess the effectiveness, safety and pharmacokinetics of ustekinumab in a large cohort of refractory UC patients. METHODS: Multicenter observational study of UC patients who received ustekinumab for active disease. The Partial Mayo Score (PMS), endoscopic activity, C-reactive protein (CRP) and faecal calprotectin (FC) were recorded at baseline and at different time points. Demographic and clinical data, adverse events (AEs) and surgeries were documented. RESULTS: A total of 108 patients were analyzed from 4 referral Spanish hospitals. The clinical remission rates were 59%, 56.5%, 57% and 69% of patients at weeks 8, 16, 24 and 52, respectively. Normalization of FC was achieved in 39.6%, 41% and 51% at weeks 8, 24 and 52, respectively. CRP normalization was observed in 79%, 75% and 76.5% of patients at weeks 8, 24 and 52, respectively. Fewer previous anti-TNF agents and loss of response to anti-TNF were associated with clinical response and normalization of FC, respectively. AEs were observed in 5 patients, and 9 underwent colectomy. Ustekinumab persistence rates were 91%, 83% and 81% at 24, 48 and 96 weeks, respectively. CONCLUSIONS: Ustekinumab demonstrated, in the real-world setting, long-term effectiveness and a favorable safety profile in a cohort of refractory UC patients.

RESUMO

BACKGROUND: The advent of new therapeutic agents and the improvement of supporting care might change the management of acute severe ulcerative colitis (ASUC) and avoid colectomy. AIMS: To evaluate the colectomy-free survival and safety of a third-line treatment in patients with ASUC refractory to intravenous steroids and who failed either infliximab or ciclosporin. METHODS: Multicentre retrospective cohort study of patients with ASUC refractory to intravenous steroids who had failed infliximab or ciclosporin and received a third-line treatment during the same hospitalisation. Patients who stopped second-line treatment due to disease activity or adverse events (AEs) were eligible. We assessed short-term colectomy-free survival by logistic regression analysis. Kaplan-Meier curves and Cox regression models were used for long-term assessment. RESULTS: Among 78 patients, 32 received infliximab and 46 ciclosporin as second-line rescue treatment. Third-line treatment was infliximab in 45 (58%), ciclosporin in 17 (22%), tofacitinib in 13 (17%) and ustekinumab in 3 (3.8%). Colectomy was performed in 29 patients (37%) during follow-up (median 21 weeks). Of the 78 patients, 32 and 18 were in clinical remission at, respectively, 12 and 52 weeks. At the last visit, 25 patients were still on third-line rescue treatment, while 12 had stopped it due to clinical remission. AEs were reported in 26 (33%) patients. Two patients died (2.6%), including one following colectomy. CONCLUSION: Third-line rescue treatment avoided colectomy in over half of the patients with ASUC and may be considered a therapeutic strategy.

RESUMO

BACKGROUND AND AIMS: Switching from the intravenous to the subcutaneous biosimilar infliximab (SC-IFX) has been shown to safely maintain clinical remission and increase drug levels in patients with Crohn's disease (CD) and ulcerative colitis (UC). The aim of this study was to evaluate long-term outcomes after switching from intravenous IFX (IV-IFX) to SC-IFX, the drug concentration thresholds for maintaining remission and other predictors for loss of response after the switch. METHODS: Multicenter observational study involving CD and UC patients who were in clinical remission for at least 24 weeks and scheduled to switch from IV-IFX to SC-IFX. RESULTS: Two hundred and twenty patients were included [74 UC (34%) and 146 (66%) CD]. IV-IFX was administered for 52.5 months [range 25-89]. Pre-switch, 106 (49%) patients were receiving intensified IV-IFX. While SC-IFX levels significantly increased following the switch from IV to SC-IFX, clinical parameters, C-reactive protein and faecal calprotectin remained unchanged during follow-up. SC-IFX levels were significantly higher between patients receiving the standard IV-IFX dose than those with the intensified dose. Immunomodulator therapy at baseline and perianal disease had no effect on IFX trough levels, whereas higher body mass index was associated with increased levels. The suggested optimal SC-IFX cut-off concentration for clinical and biochemical remission based on ROC analysis was 12.2 µg/mL (AUC: 0.62) at week 12 and 13.2 µg/mL (AUC: 0.57) at week 52. Drug persistence was 92% at week 52, with a good safety profile. CONCLUSION: Switching from IV-IFX to SC-IFX safely maintains long-term remission in patients with CD and UC. In maintenance, the optimal cut-off point associated with remission was 12-13 µg/mL.

RESUMO

BACKGROUND: Ustekinumab is approved for ulcerative colitis (UC). AIMS: To assess the durability of ustekinumab in patients with UC and its short-term effectiveness, durability and tolerability in clinical practice. METHODS: Retrospective, multicentre study of patients who had received their first ustekinumab dose at least 16 weeks before inclusion. Patients were followed until treatment discontinuation or last visit. Only patients with active disease at the start of ustekinumab treatment were considered in the effectiveness analysis. Patients who stopped ustekinumab before their last visit were considered not to be in subsequent remission. RESULTS: We included 620 patients; 155 (25%) discontinued ustekinumab during follow-up (median 12 months). Rate of discontinuation was 20% per patient-year of follow-up. Anaemia at baseline (hazard ratio, HR 1.5; 95% confidence interval [CI] 1.1-2.1), steroids at baseline (HR 1.5; 95% CI 1.06-2.08) and more severe clinical activity at baseline (HR 1.5; 95% CI 1.09-2.06) were associated with higher risk of discontinuation. At the end of induction, 226 (40%) patients were in steroid-free clinical remission. Moderate-severe vs mild disease activity at baseline (odds ratio [OR] 0.3; 95% CI 0.2-0.5), male sex (OR 0.5; 95% CI 0.4-0.8), and increased number of previous biologics (OR 0.6; 95% CI 0.6-0.8) were associated with lower likelihood of steroid-free clinical remission at week 16. One hundred and seventy-six patients (28%) had at least one adverse event. We observed no negative impact of ustekinumab on extraintestinal manifestations and/or immune-mediated diseases. CONCLUSIONS: Ustekinumab durability in UC was relatively high, and treatment was effective in highly refractory patients. The safety profile was consistent with previous studies.

RESUMO

BACKGROUND: some patients with inflammatory bowel disease (IBD) treated with antiTNF develop drug-induced psoriasis (antiTNF-IP). Several therapeutic strategies are possible. AIMS: to assess the management of antiTNF-IP in IBD, and its impact in both diseases. METHODS: patients with antiTNF-IP from ENEIDA registry were included. Therapeutic strategy was classified as continuing the same antiTNF, stopping antiTNF, switch to another antiTNF or swap to a non-antiTNF biologic. IP severity and IBD activity were assessed at baseline and 16, 32 and 54 weeks. RESULTS: 234 patients were included. At baseline, antiTNF-IP was moderate-severe in 60 % of them, and IBD was in remission in 80 %. Therapeutic strategy was associated to antiTNF-IP severity (p < 0.001). AntiTNF-IP improved at week 54 with all strategies, but continuing with the same antiTNF showed the worst results (p = 0.042). Among patients with IBD in remission, relapse was higher in those who stopped antiTNF (p = 0.025). In multivariate analysis, stopping antiTNF, trunk and palms and soles location were associated with antiTNF-IP remission; female sex and previous surgery in Crohn´s disease with IBD relapse. CONCLUSION: skin lesions severity and IBD activity seem to determine antiTNF-IP management. Continuing antiTNF in mild antiTNF-IP, and swap to ustekinumab or switch to another antiTNF in moderate-severe cases, are suitable strategies.

RESUMO

BACKGROUND AND AIMS: The development programm UNIFI has shown promising results of ustekinumab in ulcerative colitis [UC] treatment which should be confirmed in clinical practice. We aimed 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; 36% 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 in both 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.
