Patient reported-outcomes [PROs] are becoming a major therapeutic goal in IBD, both in clinical trials and in daily clinical care. Moreover, it has recently been shown that in patients with UC the absence of rectal bleeding (Mayo Clinic endoscopic Score (MCSe)=0) shows high sensitivity for detecting mucosal healing. [1] We therefore investigated the efficacy of vedolizumab, a humanized monoclonal antibody against α4 β7-integrins, in achieving PROs, especially with regard to rectal bleeding (MCSe=0).


A consecutive cohort of 60 adult IBD patients with ulcerative colitis (partial Mayo score >4) receiving vedolizumab was prospectively recruited from 9 German tertiary IBD centers. Primary endpoint was the absence of rectal bleeding (MCSe=0) as determined at week 2, 6, 14, 30 and 54, resp. Secondary endpoints included a combined endpoint (absence of rectal bleeding and stool frequency of 1 or 2, respectively, according to the Mayo Clinic Scoring system (MCSsf)). Quality of life (QoL) was evaluated by use of a visual analogue scale (VAS; 0–100). This data represents a subgroup analysis from a larger prior observational study. [2] [3]


81.7% of patients had received prior treatment with anti-TNF-antibodies, 40% of patients had been hospitalized within one year prior to vedolizumab treatment initiation. 53.4% of patients received corticosteroids at week 0 (median 20 mg; range 0–60 mg). At week 54 20/60 patients (33.3%) reported absence of rectal bleeding, 17/60 patients (28.3%) achieved steroid-free cessation of rectal bleeding. A combined endpoint of MCSe=0 and normal stool frequency (MCSsf=0) was achieved by 16.7% of patients, while 26.7% of patients experienced absence of rectal bleeding (MCSe=0) and a mild increase in stool frequency (MCSsf=1) (Table 1). Quality of life increased from 47,5 at week 0 to 70 at week 14, 72.5 at week 30 and 70 at week 54, resp.

In UC patients with a severe disease course vedolizumab treatment results in a rapid and persistent absence of rectal bleeding in one third of patients. Normalization of stool frequency occurs less frequently and may reflects chronic alterations/damages of the bowel that may not be reverted by anti-inflammatory treatment strategies in this severely ill patient population. Absence of rectal bleeding is associated with a substantial improvement in patients quality of life. However, a substantial percentage of patients still required steroid-treatment to achieve these endpoints.
