Background: Current management of mild-to-moderate ulcerative colitis (UC) involves monitoring clinical markers of disease activity, such as stool frequency (SF) and rectal bleeding (RB), and adjusting treatment accordingly. Our aim was to assess whether targeting treatment based on faecal calprotectin (FC) levels (treat-to-target; T2T) provides greater UC disease control versus a symptom-based approach. Methods: This was a pragmatic, randomised (1:1) controlled study of patients with mild-to-moderate UC (global Mayo score 2-6) treated with ≤2.4 g/day 5-aminosalicylic acid that compared the effectiveness of two management strategies with (interventional arm) and without (reference arm) FC home monitoring over 12 months of follow-up. Treatment was optimised in the interventional arm using FC values and clinical symptoms (PRO-2), while the reference arm used only PRO-2. Results: 193 patients completed the study. No significant difference was found for the primary endpoint (Mayo Endoscopic Subscore [MES] = 0 at 12 months). A numerical advantage for the interventional arm over the reference arm for the primary endpoint (37.0% vs. 33.4%, respectively) and for MES ≤ 1, RB = 0, and SF ≤ 1 at 12 months was found following imputation for missing data. The composite endpoint of MES = 0, RB = 0, and SF ≤ 1 at 12 months was achieved at a significantly higher rate in the interventional arm than the reference arm (effect size [ES]: 0.17, 95% CI 0.02-0.32; p < 0.05). A similar result was obtained for MES ≤ 1, RB = 0 and SF ≤ 1 (ES: 0.22; 95% CI 0.07-0.37; p < 0.05). Conclusions: T2T using FC monitoring was effective in patients with mild-to-moderate UC at 12 months. Further longer-term studies are required to confirm the results.
