Project description:Antiadhesion molecules are effective and safe in patients with ulcerative colitis (UC). Etrolizumab, a monoclonal antibody targeting both ?4?7 and ?E?7, represents a promising therapy for patients with UC, since this novel mechanism of action may be effective in blocking leukocyte recruitment both at the vascular and at the mucosal level. Preliminary studies show that etrolizumab is effective in inducing clinical response and remission, and mucosal healing. Moreover, new predictors of response have recently been identified, opening the way to a tailored therapeutic approach. This review of the literature aims to present and discuss the most recent evidence on etrolizumab in UC, focusing on the clinical implications of the use of etrolizumab in UC.

Tofacitinib for induction of remission in ulcerative colitis: systematic review and meta-analysis.

Project description:The aim of the study was to assess the efficacy and safety of tofacitinib and its impact on quality of life in patients with moderate-to-severe ulcerative colitis.We conducted a systematic review and meta-analysis of randomized controlled trials comparing tofacitinib with placebo or any active comparator. We searched Medline, Embase, the Cochrane Library and gray literature for articles published up to May 2017. We synthesized data using a fixed-effect model. We conducted subgroup analysis based on prior exposure to anti-tumor necrosis factor (TNF). We summarized the strength of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.We included three trials with 1220 participants. Compared with placebo, tofacitinib was effective in inducing clinical remission (odds ratio [OR] 3.84, 95% confidence interval [CI] 2.29-6.44, I2: 41%, GRADE: moderate), clinical response (OR 2.95, 95%CI 2.21-3.95, I2: 0%, GRADE: high), mucosal healing (OR 2.70, 95%CI 1.81-4.03, I2: 0%, GRADE: high). Tofacitinib was effective in both anti-TNF-naïve and -experienced patients. Tofacitinib had a favorable effect on quality of life. There were no significant differences in the safety profile in terms of the incidence of any or serious adverse events compared to placebo. The risk for infections was increased (OR 1.51, 95%CI 1.05-2.19, I2: 0%, GRADE: moderate), but the incidence of serious infections did not differ between tofacitinib and placebo.In patients with moderate-to-severe ulcerative colitis, short-term treatment with tofacitinib is effective for induction of remission and improvement of quality of life.

Etrolizumab as an induction and maintenance therapy for ulcerative colitis: A systematic review and meta-analysis of randomized controlled trials.

Project description:Background and aimEtrolizumab is a gut-targeted anti-β7 integrin monoclonal antibody. However, the evidence of etrolizumab efficacy and safety in ulcerative colitis remains inconclusive. Therefore, we aim to evaluate the safety and efficacy of etrolizumab as an induction and maintenance therapy for active moderate to severe ulcerative colitis.MethodsWe synthesized randomized controlled studies (RCTs) from MEDLINE, Scopus, EMBASE, PubMed, Web of Science, and Cochrane Library until April 2023. The risk ratio (RR) for dichotomous outcomes with the corresponding 95% confidence interval (CI) was used. The study protocol was registered in PROSPERO with ID: CRD42023437040.ResultsFive RCTs with 1849 participants were included. The etrolizumab group had a significant clinical response (RR: 1.28 with 95% CI [1.08, 1.51], P = 0.005), clinical remission rates during the induction phase (RR: 2.47 with 95% CI [1.48, 4.11], P = 0.0005), compared with the placebo group in ulcerative colitis; however, there was no statistically significant difference between the two groups, regarding the corticosteroids-free remission rate (RR: 1.92 with 95% CI [0.94, 3.92], P = 0.07). Moreover, endoscopic improvement, endoscopic remission, and histologic remission rates were observed more in the etrolizumab group during both the induction and maintenance phases. For safety outcomes, etrolizumab was significantly safer, but any adverse event was higher in the etrolizumab group than in the placebo.ConclusionEtrolizumab shows its effectiveness as both an induction and maintenance therapy for moderate or severe UC. The findings demonstrate its positive impact on clinical, endoscopic, and histologic remission rates. Regarding safety, other than any side effects, etrolizumab showed a good safety than a placebo.

Ulcerative Colitis Remission Status After Induction With Mesalazine Predicts Maintenance Outcomes: the MOMENTUM Trial.

Project description:Background and aimsThis study assessed the efficacy of maintenance treatment with multimatrix mesalazine following achievement of complete or partial remission after induction treatment with high-dose multimatrix mesalazine.MethodsIn this phase 3b/4, open-label, multicentre, prospective, single-arm study, patients with mild-to-moderate ulcerative colitis were treated with multimatrix mesalazine 4.8g/day once daily for 8 weeks [induction phase]. At Week 8, those who achieved complete or partial remission, based on predefined clinical and endoscopic criteria, were eligible to receive 12 months of multimatrix mesalazine 2.4g/day once daily maintenance therapy. The primary endpoint was the proportion of patients in complete remission at Month 12.ResultsA total of 717 patients received induction treatment; 25.9% and 39.3% of patients achieved complete and partial remission, respectively, at Week 8. A total of 461 patients entered the maintenance phase. The likelihood of remaining in/achieving complete remission at Month 12 was higher for patients who entered the maintenance phase in complete remission compared with those who began maintenance in partial remission [47.8% vs 26.0%; p < 0.001]. At Month 12, mucosal healing [endoscopy score ≤ 1] was demonstrated in 76.4% [139/182] and 63.5% [176/277] of those who were in complete and partial remission, respectively, at the end of induction.ConclusionPatients achieving complete remission before dose reduction were more likely to remain in remission at Month 12.
