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.
