We characterized the profile of Crohn’s disease (CD) or ulcerative colitis (UC) biologic-naïve patients (starting a new therapy with vedolizumab or TNFα-antagonists), their baseline disease activity predictors, and their perception of the quality of life (HRQoL). The VEDOIBD-Study is a real-world study on the effectiveness of vedolizumab vs other biologics as induction and maintenance therapy for CD and UC. A total of 627 CD and 546 UC patients were enrolled from IBD-experienced centers across Germany. In both biologic-naïve vedolizumab (n=397) and anti-TNF (n=359) patients, CD and UC disease severity and HRQoL predictors were analyzed with logistic regression. The results were reported as odds ratio (OR) and 95% confidence interval (CI). When compared to biologic-naïve anti-TNF patients, a first biological therapy with vedolizumab was considered for older CD patients, with a less complicated though longer disease course, and with a history of comorbidities. No differences in (unmet) needs were observed among patients with UC. The presence of extra-intestinal manifestations in biologic-naïve anti-TNF patients with CD (OR (95% CI): 3.83 (1.69–8.68)) and, in both biologic-naïve groups of patients with UC, stool frequency (2.00 (1.25–3.19); 1.82 (1.10–3.02), respectively) and rectal bleeding (2.24 (1.20–4.18); 1.92 (1.19–3.11), respectively) emerged as the most important predictors of disease severity, which in turn were also significantly associated with a worse HRQoL. This study highlights the existence of unmet medical needs of patients with CD or UC, for whom a new biological therapy is planned as part of the VEDOIBD-Study, which considerably impacts their HRQoL.
