Project description:<h4>Background/aims</h4>Studies on elective switching to the subcutaneous (SC) formulation of infliximab revealed comparable efficacy and safety and higher infliximab level than those exhibited by intravenous (IV) infliximab. However, no studies have reported on the effectiveness of SC switching in ulcerative colitis (UC) patients who experienced IV infliximab failure during maintenance treatment.<h4>Methods</h4>This retrospective study included UC patients who had been switched to SC infliximab because of IV infliximab failure, between January 2021 and January 2023. Group A was defined as having clinically and biochemically active UC (secondary loss of response), and group B consisted of patients with stable symptoms but biochemically active UC.<h4>Results</h4>Twenty-three patients met the inclusion criteria: 15 in group A and eight in group B. The serum infliximab levels significantly increased after SC switching in both groups. The electively switched group also exhibited increased infliximab levels after SC switching. Patients in group A showed improved partial Mayo score with a significant decrease in fecal calprotectin and C-reactive protein after switching. In group B, the fecal calprotectin level significantly decreased without clinical relapse after switching. A high proportion of patients (≥80%) in both groups achieved clinical and/or biochemical responses at the last follow-up. During the follow-up period, only two patients in group A discontinued SC infliximab, and only one complained of severe injection site reaction.<h4>Conclusions</h4>In UC patients who experience IV infliximab failure during maintenance treatment, switching to SC infliximab may be a promising option because of better efficacy and safety.

Project description:<h4>Background and objectives</h4>Ulcerative colitis is highly prevalent in Canada and cost-effective ulcerative colitis therapies are warranted. Vedolizumab subcutaneous (SC) formulation was recently approved for ulcerative colitis maintenance therapy. We assessed vedolizumab SC cost effectiveness vs conventional and advanced therapeutics in patients with moderately to severely active ulcerative colitis from a Canadian public healthcare payer perspective.<h4>Methods</h4>A hybrid decision tree/Markov model was developed to evaluate vedolizumab SC costs, quality-adjusted life-years, and cost effectiveness vs conventional therapy, adalimumab SC, infliximab intravenous, golimumab SC, tofacitinib, ustekinumab SC, and vedolizumab intravenous. This model predicts the number of patients achieving clinical response and remission after treatment induction, and sustained benefit during maintenance treatment. To account for statistical uncertainties, the base-case analysis was conducted in a probabilistic manner. Scenario analyses examined the impact of previous treatment with anti-tumor necrosis factor agents, dose escalation, loss of efficacy, and treatment adherence.<h4>Results</h4>In the base-case analysis, conventional therapy was the most cost-effective therapeutic option in the overall population. Vedolizumab SC was cost effective and dominant compared with other advanced therapies (adalimumab, golimumab, infliximab, tofacitinib 5 mg, ustekinumab, and vedolizumab intravenous). The annual vedolizumab SC cost per patient was reduced vs ustekinumab SC, tofacitinib 5 mg, vedolizumab intravenous, and golimumab SC by $47,024, $3251, $2120, and $2004 (Canadian dollars), respectively, and exceeded that of infliximab, adalimumab, and conventional therapy by $582, $3293, and $41,024, respectively. Among the treatments, vedolizumab SC generated the highest quality-adjusted life-years overall (14.21), which translated into the best incremental cost per quality-adjusted life-years gained over conventional therapy in the overall population ($109,374) and in anti-tumor necrosis factor-naïve and anti-tumor necrosis factor-experienced patients ($41,658/$114,287).<h4>Conclusions</h4>Conventional therapy offered the most cost-effective therapeutic option followed by vedolizumab SC. Based on a $50,000/quality-adjusted life-year threshold, vedolizumab was cost effective in anti-tumor necrosis factor-naïve patients but not the overall population also when compared to conventional therapy.

Project description:<h4>Background/aims</h4>A subgroup analysis was conducted in Japanese patients with moderate to severe ulcerative colitis (UC) enrolled in the phase 3 VISIBLE 1 study, which evaluated the safety and efficacy of a new vedolizumab subcutaneous (SC) formulation.<h4>Methods</h4>Eligible patients received open-label infusions of vedolizumab 300 mg intravenous (IV) at weeks 0 and 2 in the induction phase. Patients with clinical response by complete Mayo score at week 6 entered the double-blind maintenance phase and were randomized to vedolizumab 108 mg SC every 2 weeks, placebo, or vedolizumab 300 mg IV every 8 weeks. The primary endpoint was clinical remission (complete Mayo score ≤ 2 points; no individual subscore > 1 point) at week 52.<h4>Results</h4>Of 49 patients who entered the induction phase, 22 out of 49 patients (45%) had clinical response at week 6 and were randomized to vedolizumab 108 mg SC (n = 10), placebo (n = 10), or vedolizumab 300 mg IV (n = 2). At week 52, 4 out of 10 patients (40%) who received vedolizumab SC had clinical remission versus 2 out of 10 patients (20%) who received placebo (difference: 20% [95% confidence interval, -27.9 to 61.8]). Two patients (2/10, 20%) who received vedolizumab SC experienced an injection-site reaction versus none who received placebo.<h4>Conclusions</h4>Our results indicate that the efficacy of vedolizumab SC in a subgroup of Japanese patients with UC are similar with those in the overall VISIBLE 1 study population, and with those established with vedolizumab IV. The safety and tolerability of vedolizumab SC were generally similar to that established for vedolizumab IV. (ClinicalTrials.gov ID NCT02611830; EudraCT 2015-000480-14).

Project description:<h4>Background</h4>Infliximab is a chimeric monoclonal antibody against tumour necrosis factor-alpha for the treatment of Crohn's disease (CD) and ulcerative colitis (UC). Recently, a subcutaneous formulation of CT-P13, an infliximab biosimilar, was approved for clinical use.<h4>Aims</h4>To characterise CT-P13 pharmacokinetics (PK) and its clinically relevant determinants after subcutaneous administration through population PK modelling.<h4>Methods</h4>Data from a two-part Phase I study with intravenous (5 mg/kg) and variable maintenance subcutaneous dosing of CT-P13 with frequent PK sampling in patients with CD or UC were used. Population PK analysis was conducted by non-linear mixed effects modelling. Covariates affecting PK parameters were chosen based on their clinical relevance (effect size of ≥20%) using a full fixed-effect modelling approach.<h4>Results</h4>CT-P13 PK was described by a two-compartment model with linear elimination. The half-life in a typical 70 kg patient with serum albumin of 44 g/L was 10.8 days. The typical value for clearance was 0.355 L/d, absorption constant 0.273/d, bioavailability 79.1%, central volume of distribution 3.10 L and peripheral volume of distribution 1.93 L. Clinically relevant covariates affecting clearance were body weight (+43.2% from 70 to 120 kg), the presence of anti-drug antibodies (+39%) and serum albumin concentration (+30.1% from 44 to 32 g/L). Simulated drug exposure was comparable between routes of administration for patients weighing 50 or 70 kg, but lower with subcutaneous dosing in patients weighing 120 kg.<h4>Conclusions</h4>This first population PK model for subcutaneous CT-P13 supports fixed subcutaneous maintenance dosing, although heavy patients had lower cumulative drug exposure.

Project description:<h4>Background</h4>Biological therapies have changed the landscape of pharmacological management of ulcerative colitis (UC). However, a large proportion of patients do not respond to biologics, lose their response over time, or present adverse drug events. This study aims to assess therapeutic response and treatment persistence to adalimumab, infliximab, and vedolizumab, 3 agents widely used in a tertiary referral center of Saguenay-Lac-Saint-Jean (Quebec, Canada).<h4>Methods</h4>We conducted a retrospective population-based study with a thorough review of patients' medical charts. Adults at UC diagnosis, with current or past use of adalimumab, infliximab, or vedolizumab, were included in the study. Clinical data were collected in order to assess response phenotypes and persistence to treatment. Kaplan-Meier curves were performed to assess treatment persistence, and predictors for discontinuation were assessed using Cox regression analyses.<h4>Results</h4>A total of 134 patients were included in this study. For the cases exposed to adalimumab, infliximab, and vedolizumab, 56.9%, 62.5%, and 47.5% were responders, respectively. Mean persistence rates (95% CI) were 5.5 (4.3-6.6), 10.1 (8.7-11.5), and 3.6 (2.9-4.2) years for adalimumab, infliximab, and vedolizumab, respectively. Increased persistence rates were observed in biologic-naïve patients treated with infliximab in comparison to those with the previous exposition to 2 biologics, but no such effect was observed for adalimumab or vedolizumab. Overall, 61.9% of cases had adverse drug events and of these, 6 led to treatment discontinuation.<h4>Conclusion</h4>This study presents long-term treatment persistence data with adalimumab, infliximab, and vedolizumab, showing that more than half of cases treated with these biologics remained on treatment at least 24 months after initiation.

Project description:<h4>Background</h4>Although studies have compared on-treatment effectiveness of infliximab and vedolizumab in patients with ulcerative colitis (UC), there has been limited comparison of treatment sequencing and long-term patient-centred outcomes.<h4>Aim</h4>To compare infliximab-first and vedolizumab-first strategy in biologic-naïve patients with UC.<h4>Methods</h4>We conducted a retrospective cohort study in biologic-naïve patients with UC who were treated first with either infliximab or vedolizumab between 2015 and 2021 and followed over 30 months following initiation. Primary outcomes were the number of hospitalisations, corticosteroid courses and serious infections with either strategy (regardless of switch to alternative therapies) within 30 months. We matched the groups 1:1 through cardinality matching, and fit logistic and zero-inflated negative binomial models to compare outcomes.<h4>Results</h4>We included 181 patients (94 vedolizumab-first and 87 infliximab-first treatment strategy). Of these, 144 were matched 1:1. There was no significant difference in the incidence of IBD-related hospitalisations (incidence rate ratio [IRR], 1.98 [95% CI, 0.64-6.10]), corticosteroid courses (0.66 [0.38-1.15]) and serious infections (5.26 [0.62-45.45]), with comparable incidence of medication switches to alternative advanced therapies (1.08 [0.42-2.81]). At 30 months, there was no difference in proportion of patients in clinical remission (69.4% vs. 76.4%; p = 0.45) and endoscopic remission (55.6% vs. 65.3%; p = 0.36).<h4>Conclusion</h4>In patients with UC, long-term effectiveness and safety outcomes are comparable with infliximab-first and vedolizumab-first treatment strategies at 30 months. This can help to guide selection of treatment strategies in patients with UC.

Project description:<h4>Background</h4>Real-world comparative benefits and risks of infliximab (IFX) and adalimumab (ADA) in patients with ulcerative colitis (UC) are unclear.<h4>Aim</h4>To evaluate the comparative effectiveness and safety of IFX and ADA in patients with UC who were new users of anti-TNF agents.<h4>Methods</h4>Using an administrative claims database (Optum Labs Data Warehouse), we identified patients who received first anti-TNF (IFX, ADA) prescription after a 12-month period without any anti-TNF treatment (baseline), and with a minimum 6-month follow-up after anti-TNF initiation. Primary outcome measures were: all-cause and UC-related hospitalisation, abdominal surgery, corticosteroid use >60 days after starting anti-TNF, and serious infections. We performed 2:1 propensity-score matched Cox proportional hazard analysis, and inverse probability-of-treatment weight (IPTW) analysis, accounting for healthcare utilisation, comorbidities and use of UC-related medication.<h4>Results</h4>We included 1400 new users of anti-TNF agents (age, 43 ± 15 years; 52% males), from 2006 to 2014. On propensity-score matched analysis, there was no significant difference in the risk of UC-related hospitalisation [IFX vs. ADA; adjusted hazard ratio (aHR), 1.04; 95% confidence interval (CI) 0.71-1.51], corticosteroid use (aHR, 0.85; 95% CI, 0.68-1.06) and serious infections (aHR, 0.62; 95% CI, 0.29-1.34) between IFX- and ADA-treated patients; the number of surgical events was very small. On IPTW analysis, risk of corticosteroid use was significantly lower in IFX - as compared to ADA - treated patients (aHR, 0.82; 95% CI, 0.68-0.99). Results were stable on multiple sensitivity analyses.<h4>Conclusions</h4>In a large retrospective cohort of patients with UC who were new users of anti-TNF agents, IFX-treated patients may have lower corticosteroid use than ADA-treated patients, but risk of hospitalisation and serious infections were comparable.

Project description:<h4>Background & aims</h4>We aimed to compare safety and effectiveness of vedolizumab to tumor necrosis factor (TNF)-antagonist therapy in ulcerative colitis in routine practice.<h4>Methods</h4>A multicenter, retrospective, observational cohort study (May 2014 to December 2017) of ulcerative colitis patients treated with vedolizumab or TNF-antagonist therapy. Propensity score weighted comparisons for development of serious adverse events and achievement of clinical remission, steroid-free clinical remission, and steroid-free deep remission. A priori determined subgroup comparisons in TNF-antagonist-naïve and -exposed patients, and for vedolizumab against infliximab and subcutaneous TNF-antagonists separately.<h4>Results</h4>A total of 722 (454 vedolizumab, 268 TNF antagonist) patients were included. Vedolizumab-treated patients were more likely to achieve clinical remission (hazard ratio [HR], 1.651; 95% confidence interval [CI], 1.229-2.217), steroid-free clinical remission (HR, 1.828; 95% CI, 1.135-2.944), and steroid-free deep remission (HR, 2.819; 95% CI, 1.496-5.310) than those treated with TNF antagonists. Results were consistent across subgroup analyses in TNF-antagonist-naïve and -exposed patients, and for vedolizumab vs infliximab and vs subcutaneous TNF-antagonist agents separately. Overall, there were no statistically significant differences in the risk of serious adverse events (HR, 0.899; 95% CI, 0.502-1.612) or serious infections (HR, 1.235; 95% CI, 0.608-2.511) between vedolizumab-treated and TNF-antagonist-treated patients. However, in TNF-antagonist-naïve patients, vedolizumab was less likely to be associated with serious adverse events than TNF antagonists (HR, 0.192; 95% CI, 0.049-0.754).<h4>Conclusions</h4>Treatment of ulcerative colitis with vedolizumab is associated with higher rates of remission than treatment with TNF-antagonist therapy in routine practice, and lower rates of serious adverse events in TNF-antagonist-naïve patients.
