- Proportion of subjects in Clinical Remission [ Time Frame: Week 12 ]Clinical remission defined by a modified Mayo Score with an endoscopic subscore less than or equal to 1, stool frequency subscore less than or equal to 1 and rectal bleeding subscore = 0
- Proportion of subjects with endoscopic improvement [ Time Frame: Week 12 ]Endoscopic improvement defined as decrease of 1 point in Mayo endoscopy score or an absolute endoscopy score of 1 or less.
- Mean change from baseline at Week 12 in Geboes histology score [ Time Frame: Baseline, Week 12 ]Mean change from baseline at Week 12 in Geboes score.
- Proportion of subjects with a clinical response [ Time Frame: Week 12 ]Clinical response defined with a decrease from baseline of at least 3 points in total Mayo score with at least 30% change, accompanied by at least one point decrease or absolute score of 0 or 1 in rectal bleeding subscore.
- Proportion of subjects with change from baseline in partial Mayo Score of 2 or less with no individual subscore >1 [ Time Frame: Weeks 2, 4, 6, 8, 12 ]Proportion of subjects with partial Mayo score <=2 with no individual subscore of > 1 at Week 2, 4, 6, 8 and 12
- Serum concentrations of PF 06687234 [ Time Frame: Baseline through Week 12 ]Measure serum concentration of PF-06687234 at baseline, Week 1, 3, 7, 11, 12, and 16
- Incidence of the development of HAFAs and Nabs against PF 06687234. [ Time Frame: Baseline through Week 16 ]Measure HAFA and neutralizing antibody against IL10 at screen, baseline, Week 3, 7, 11, 12, and 16
