This is a multicenter, prospective study of dose adjustment of golimumab in patients with ulcerative colitis who will initiate golimumab treatment (naïve to anti-TNF) or after failure (or exposure) to one anti-TNF, which aims to analyze serum golimumab levels and anti- golimumab antibody (ADA) levels during the induction (week 6) and maintenance phases (week 14, 30 and 54) and correlate them with efficacy parameters.

Clinical response at week 6,14, 30 and 54 will be correlated to serum golimumab levels and anti-golimumab antibody levels.
Golimumab dosing will be optimized in patients without clinical response at week 6.

Correlation between serum Golimumab levels and clinical response.
Serum Golimumab levels will be measured and clinical activity evaluation will be assessed according to the partial Mayo score and biochemical parameters such as C-reactive protein and calprotectin.
Time frame: Week 6.
Correlation between anti-Golimumab antibody levels and clinical response.
Anti-golimumab antibody levels will be measure and clinical activity evaluation will be performed according to the partial Mayo score and biochemical parameters such as C-reactive protein and calprotectin.
Time frame: Week 6.
Treatment optimization outcome.
Analyze the percentage of non-responder patients or patients with partial response at week 6 who achieve response/remission at week 14 after treatment optimization.
Time frame: Week 14
Correlation between mucosal healing and serum Golimumab levels.
An endoscopy will be performed at the end of the treatment and serum Golimumab levels will be measured.
Time frame: Week 54
Identification of cut-off values of serum golimumab concentration
Identify useful cut-off values of serum golimumab concentration for use in ulcerative colitis practice.
Time frame: Week 6
Correlation between mucosal healing and anti-Golimumab antibody levels.
An endoscopy will be performed at the end of the treatment and anti-Golimumab antibody levels will be measured.
Time frame: Week 54
