Proportion of patients with clinical remission, clinical response, and endoscopic remission/rectal bleeding score of 0 in the mITT population
(A) Clinical remission at week 6 and week 10. (B) Clinical response (3-point decrease and 30% reduction in Mayo Clinic Score and 1-point decrease or more in rectal bleeding subscore or absolute rectal bleeding subscore of 0 or 1) at week 6 and week 10. (C) Endoscopic and rectal bleeding subscores of 0 at week 6 and week 10. LD=loading dose. mITT=modified intention-to-treat. *p<0·05 (vs placebo). †p<0·01 (vs placebo).

Subgroup analyses of clinical remission at week 10 in the mITT population
(A) Proportion of patients by concomitant treatment with steroids. (B) Proportion of patients by immunomodulators. (C) Proportion of patients by previous TNF antagonist exposure; one patient in the placebo group, one patient in the etrolizumab 100 mg group, and two patients in the etrolizumab 300 mg plus LD group group who received anti-TNF but had an unacceptable adverse event to it were excluded from the analysis. (D) Proportion of patients by geographical region; specific country data can be found in the appendix. LD=loading dose. mITT=modified intention-to-treat. TNF=tumour necrosis factor. *p<0·05 (vs placebo). †p<0·01 (vs placebo).

Clinical remission according to baseline colonic biopsy αE levels
(A) Clinical remission according to gene expression of integrin αE, as measured by quantitative PCR, in the colonic biopsy sample taken at baseline. (B) Clinical remission according to levels of αE+ cells in the colonic biopsy sample taken at baseline. LD=loading dose. TNF=tumour necrosis factor.
