Upadacitinib Induction and Maintenance Therapy Improves Abdominal Pain, Bowel Urgency, and Fatigue in Patients With Ulcerative Colitis: A Post Hoc Analysis of Phase 3 Data

Inflamm Bowel Dis. 2023 Nov 2;29(11):1723-1729. doi: 10.1093/ibd/izad016.

Abstract

Background: This post hoc analysis of a large, phase 3 program evaluated the effects of upadacitinib on fatigue, bowel urgency, and abdominal pain in patients with moderately to severely active ulcerative colitis.

Methods: Induction data were pooled from 2 identical studies, the U-ACHIEVE induction and U-ACCOMPLISH studies. Patients in these studies received upadacitinib 45 mg once daily or placebo as induction treatment. Responders to induction treatment were rerandomized in the U-ACHIEVE maintenance study to upadacitinib 15 mg once daily, upadacitinib 30 mg, or placebo. The percentage of patients reporting no abdominal pain and no bowel urgency daily via an electronic diary and a meaningful within-person change (≥5 points) in the Functional Assessment of Chronic Illness Therapy-Fatigue score were evaluated.

Results: The results demonstrated a statistically significantly greater percentage of patients reporting no abdominal pain and absence of bowel urgency observed from week 2 (P < .001), with upadacitinib induction treatment and clinically meaningful improvements in Functional Assessment of Chronic Illness Therapy-Fatigue score observed at week 8 (P < .001), when compared with placebo. The maintenance study showed that significant and meaningful improvements in abdominal pain, bowel urgency, and Functional Assessment of Chronic Illness Therapy-Fatigue score achieved during induction were sustained through 52 weeks of maintenance treatment in upadacitinib- vs placebo-treated patients.

Conclusions: The findings of this study support the additional benefit of upadacitinib in treating moderately to severely active ulcerative colitis by demonstrating a statistically significant impact on clinically meaningful symptoms of fatigue, bowel urgency, and abdominal pain.(U-ACHIEVE induction and maintenance studies; NCT02819635; U-ACCOMPLISH induction study; NCT03653026).

Plain language summary

A significantly higher percentage of patients with moderately to severely active ulcerative colitis reported no abdominal pain, no bowel urgency, and a meaningful change in fatigue following 8-week upadacitinib induction treatment and 52-week maintenance treatment compared with placebo.
