• Incidence, nature and severity of clinical laboratory test abnormalities

Secondary Objective: Secondary Objectives:
To explore the effectiveness of PUR 0110 rectal enema, 250 mg, 500 mg and 1000 mg OD versus placebo OD in patients with active mild-to-moderate distal ulcerative colitis.

To evaluate through an exploratory analysis the effect of PUR 0110 rectal enema on:
(a) serum lutein levels; and
(b) the concentrations of biomarkers of inflammation, in vivo oxidative stress, apoptosis and antioxidant defence mechanisms in the plasma, serum, feces, urine and biopsy tissue of patients with active mild-to-moderate distal ulcerative colitis.

Main Objective: To evaluate the safety and tolerability of PUR 0110 rectal enema 250 mg, 500 mg and 1000 mg OD versus placebo (vehicle) OD in patients with active mild-to-moderate distal ulcerative colitis
