E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To evaluate the correlation of serum soluble ST2 levels with endoscopic activity (endoscopic Mayo score) at week 6 in moderate to severe UC subjects under golimumab treatment.
- To evaluate the correlation of serum soluble ST2 with histological activity (Geboes index) at week 6 in moderate to severe UC subjects under golimumab treatment. |
|
E.2.2 | Secondary objectives of the trial |
- Evaluate correlation of serum solubleS T2 levels with endoscopic activity (Mayo score) at Wk16 in moderate to severe UC subjects under golimumab - Evaluate correlation of serum soluble ST2 levels with histological activity (Geboes index) at week 16 in moderate to severe UC subjects under golimumab - Correlate serum soluble ST2 levels with fecal calprotectin, at wk 6 and wk16 in moderate to severe UC subjects under golimumab - Correlate serum soluble ST2 with clinical activity (total Mayo score) at wk6 and wk16 in moderate to severe UC subjects under golimumab - Evaluate the potential of serum soluble ST2 as a predictor of endoscopic response (endoscopic Mayo score) to golimumab in moderate to severe UC subjects - Evaluate correlation between serum soluble ST2 levels with maintenance of endoscopic response (endoscopic Mayo score) to golimumab - Correlate Mayo endoscopic score with UCEIS overall score at wk6 and wk16 in moderate to severe UC subjects under golimumab |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time. |
|
E.3 | Principal inclusion criteria |
Subjects with a diagnosis of moderate to severe ulcerative colitis will be selected to participate in the trial.
Inclusion criteria: Age 18 years or older at time of enrollment; diagnosis of moderate to severe ulcerative colitis at inclusion (defined as a clinical Mayo score ≥6) including endoscopy that shows inflammation as judged by a Mayo endoscopy score ≥2; subject is eligible to receive golimumab as per product monograph; signed the informed consent |
|
E.4 | Principal exclusion criteria |
Exclusion criteria: as per golimumab’s product monograph; history of asthma, autoimmune diseases, hypertension. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
- endoscopic activity of disease (measured by endoscopy Mayo subscore) at 6 weeks in UC subjects receiving golimumab; - histological activity (measured by Geboes index score) at 6 weeks in UC subjects receiving golimumab. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
- the correlation between serum soluble ST2 with endoscopic activity of disease (measured by endoscopy Mayo subscore) at 16 weeks in UC subjects receiving golimumab, through the Spearman correlation coefficient;
- the correlation between serum soluble ST2 histological activity (measured by Geboes index score) at 16 weeks in UC subjects receiving golimumab, through the Spearman correlation coefficient.
- Serum soluble ST2 levels at baseline, Week 6 and Week 16 will be correlated with fecal calprotectin levels at baseline, week 6 and week 16 through Pearson correlation coefficient or Spearman correlation coefficient in case the normality assumption is not verified. The two biomarkers will be categorized by the cut-offs and Cohen's kappa coefficient will be obtained.
- Serum soluble ST2 levels at baseline, week 6 and week 16 will be correlated with clinical activity (total Mayo score), through Spearman correlation coefficient.
- Comparative analyses of means (active disease versus inactive disease at week 6) with serum ST2 at baseline and change between baseline and week 6.
- Comparative analyses of subjects who achieved response at week 6 and maintained through week 16 versus subjects who did not maintain response, regarding serum soluble ST2 at baseline, week 6 and change between baseline and week 6. ROC curve analysis of the serum soluble ST2 at week 6 regarding maintenance of response between week 6 and 16 will be performed. This exploratory analysis will detect the cut-off levels of the serum soluble ST2 at week 6 associated with maintenance of response. |
