High treatment persistence rate and significant endoscopic healing among real-life patients treated with vedolizumab – a Finnish Nationwide Inflammatory Bowel Disease Cohort Study (FINVEDO)

Abstract Background Vedolizumab (VDZ) is the first biological therapy for Inflammatory Bowel Disease (IBD) tested, in pivotal trials, on patients up to 80 years old and has usually been presented as a safer choice in frail patients. However, real-world data on the effectiveness and safety of VDZ in elderly (≥ 65 years) are scarce. The aim of this study is to explore the effectiveness and safety of VDZ in a large real-life cohort of elderly IBD patients, with a 2 years follow-up. Methods The Long-term Italian Vedolizumab Effectiveness (LIVE) study included CD and UC patients started on VDZ from April 2016 to June 2017 at 40 centres of the Italian Group for the study of inflammatory bowel disease (IG-IBD). Patients were prospectively followed-up to June 2019. Co-primary endpoints were to evaluate cumulative VDZ treatment persistence and safety. Results Of 966 patients, 174 (18%; 81 CD, 93 UC) were ≥ 65 years old at enrolment. Mean disease duration at baseline was 10.9 years ± SD10 (CD 12.5 ± 11, UC 9.6 ± 9). VDZ was used as a first biologic therapy in 78 patients (44.8%). 25 patients (14.4%) had a history of previous cancer. The majority of CD patients had a stricturing behaviour (45, 55.6%) and had already undergone surgery (41, 49.4%). 48 UC patients (51.6%) had extensive colitis. Moderate-to-severe endoscopic activity was present in 80% of CD and in 92% of UC, according to SES-CD and endoscopic Mayo score, respectively. Cumulative VDZ treatment persistence at 12 and 24 months was 71.8% (71.6% CD and 72.0% UC) and 54% (54.2% CD and 53.8%% UC), respectively. 52.9% (40 CD; 52 UC), 4.0%, 3.5%% and 2.9% of patients were on concomitant steroids at baseline, 6, 12, and 24 months, respectively. Clinical remission at 12 and 24 months was achieved in 28.7% (31 CD and 29 UC) and in 31.6% (25 CD and 30 UC) of patients. Mean C-reactive protein was 15.6 mg/l ± SD 20 (CD 15.9 ± 21; UC 15.2 ± 19) at baseline and dropped to 8.4 mg/l ± 10 (CD 8.0 ± 8, UC 8.9 ± 11) at 12 months and to 5.9 mg/l ± 6 (CD 5.8 ± 5, UC 6 ± 7) at 24 months. Dose escalation was necessary for 20.3% and 24.7% of patients within the first 12 and 24 months. 44 adverse events were reported: 16 infections.,6 new diagnosis of cancer/dysplasia (2 colon, 1 kidney, 1 prostate, 1 lung, 1 melanoma), 4 arthritis, 3 skin rash, 2 drug-induced cholestasis,11 miscellaneous. 11 patients (6.3%) underwent VDZ withdrawal because of adverse events (6 new diagnosis of cancer/dysplasia; 4 infections; 1 cholestasis). One patient died for pneumonia complications. Conclusion In this preliminary analysis of the largest reported real-world cohorts of elderly IBD patients treated with VDZ, up to 55% of patients persisted on therapy after two years; an acceptable safety profile was observed throughout the entire follow-up period.

Abstract Background Though a single nonmedical switch from the originator infliximab (IFX) to a biosimilar is considered effective and safe for most patients with inflammatory bowel disease (IBD), very limited data are available on multiple successive switches. Methods We performed a prospective multicenter cohort study of adult IBD patients who underwent 2 switches from the originator IFX to CT-P13 to SB2 (group 1), 1 switch from CT-P13 to SB2 (group 2), and 1 switch from the originator IFX to CT-P13 (group 3). Patients were assessed at 4 and 12 months since the most recent switch for remission using clinical (physician’s assessment) and biochemical (C-reactive protein [CRP], and fecal calprotectin [FC]) measures. Patients discontinuing treatment for ineffectiveness or adverse events before month 12 were imputed as nonremitters. Results One hundred seventy-six patients (Crohn’s disease 71%, ulcerative colitis 27.8%, IBD unclassified 1.2%; group 1, 69; group 2, 80; group 3, 27) were included. At 12 months after the most recent switch 76.9% (40 of 52, group 1), 65.7% (46 of 70, group 2) and 76.9% (20 of 26, group 3) of patients were in clinical remission. Treatment persistence at 12 months was 85.0%, 87.0%, and 70.1%, respectively. There were no significant differences in the rate of clinical, CRP, FC remission, or treatment persistence at 12 months between the 3 groups. Infusion reactions occurred in 1.7% of patients (3/176), all in patients with antidrug antibodies from group 2. Conclusions Multiple successive switching and switching between biosimilars of IFX seemed to be effective and safe.

Abstract Background The aim of this study was to investigate the factors associated with treatment persistence for infliximab and adalimumab, as 1st or 2nd line anti-TNF therapy, in patients with inflammatory bowel disease (IBD). Methods A retrospective study of patients with IBD from the registry of our department who received infliximab (IFX) or adalimumab (ADA), during the period of 2002–2019 was performed. The persistence rate of IFX and ADA at 1 and 3 years from treatment initiation as 1st and 2nd line anti-TNF therapy respectively was calculated. In addition, possible related factors were analyzed. Results We included 185 patients with IBD, naive to biologics, who initiated with anti-TNF treatment [105 men (57%), mean age (± SD) 44.5 ± 14.7 years, Crohn’s disease 144 (78%), median disease duration (IQR) 13 (7–20) years, 120 (65%) under IFX, 100 (55%) in combination with immunosuppressive therapy for at least 6 months]. In 59 patients [Crohn’s disease 47 (80%)] IFX or ADA was used as 2nd line anti-TNF therapy. The duration of administration and persistence rate of IFX and ADA as 1st and 2nd line treatment are shown in Table 1. In univariate analysis statistically significant associations between the persistence rates of anti-TNF therapy as first-line therapy, with the use of immunosuppressants (P = 0.04) and treatment intensification (P = 0.01) in both 1st and 3rd year (P = 0.01 and 0.04 respectively) were found. No other significant association between demographic, disease type and clinical parameters and treatment persistence was found. Regarding the 2nd line anti-TNF treatment, persistence of therapy in the 1st year was associated with treatment intensification (P = 0.02) and in the 3rd year of administration with the combination with immunosuppressants (P = 0.05). In multivariate analysis only the use of immunosuppresants remained statistically significant associated both in 1st and 3rd year of treatment in 1st line therapy (P=0.05 and P=0.003 respectively). This was also the case in 2nd line therapy but only in the 3rd year of treatment (P=0.05). Conclusion The persistence rates of IFX and ADA used both as a 1st and 2nd line therapy in IBD patients are significantly associated with the combined use of immunosuppressants.
