Background/Aims
A subgroup analysis was conducted in Japanese patients with moderate to severe ulcerative colitis (UC) enrolled in the phase 3 VISIBLE 1 study, which evaluated the safety and efficacy of a new vedolizumab subcutaneous (SC) formulation.
Methods
Eligible patients received open-label infusions of vedolizumab 300 mg intravenous (IV) at weeks 0 and 2 in the induction phase. Patients with clinical response by complete Mayo score at week 6 entered the double-blind maintenance phase and were randomized to vedolizumab 108 mg SC every 2 weeks, placebo, or vedolizumab 300 mg IV every 8 weeks. The primary endpoint was clinical remission (complete Mayo score ≤ 2 points; no individual subscore > 1 point) at week 52.
Results
Of 49 patients who entered the induction phase, 22 out of 49 patients (45%) had clinical response at week 6 and were randomized to vedolizumab 108 mg SC (n = 10), placebo (n = 10), or vedolizumab 300 mg IV (n = 2). At week 52, 4 out of 10 patients (40%) who received vedolizumab SC had clinical remission versus 2 out of 10 patients (20%) who received placebo (difference: 20% [95% confidence interval, –27.9 to 61.8]). Two patients (2/10, 20%) who received vedolizumab SC experienced an injection-site reaction versus none who received placebo.
Conclusions
Our results indicate that the efficacy of vedolizumab SC in a subgroup of Japanese patients with UC are similar with those in the overall VISIBLE 1 study population, and with those established with vedolizumab IV. The safety and tolerability of vedolizumab SC were generally similar to that established for vedolizumab IV. (ClinicalTrials.gov ID NCT02611830; EudraCT 2015-000480-14)

Efficacy and safety of two pH-dependent-release mesalamine doses in moderately active ulcerative colitis: a multicenter, randomized, double-blind, parallel-group study: Yasuo Suzuki, Mitsuo Iida, Hiroaki Ito, Isamu Saida, Toshifumi Hibi; Intest Res 2016;14(1):50-59.

<b>Background/Aims</b><br/>

The therapeutic effect of mesalamine is considered to be dose-dependent; however, no consensus has been reached regarding the optimal doses for individual patients. This study aimed to provide new insight for dose optimization using two doses of pH-dependent release mesalamine for induction of remission of moderately active ulcerative colitis (UC).

Methods

In a multicenter, double-blind, randomized study, 110 patients with moderately active UC were assigned to two groups after treatment with a constant dose of mesalamine. Fifty-five patients were treated with a pH-dependent release formulation of 3.6 or 4.8 g/day for 8 weeks. The primary endpoint was a decrease in the UC disease activity index (UCDAI) adjusted by covariates.

Results

In the full analysis set (n=110), the mean decrease in UCDAI was 3.1 in the 3.6 g/day group and 3.4 in the 4.8 g/day group (P>0.05). In a subgroup analysis, the effectiveness of the 4.8 g/day dose was greater in particular populations, such as those who had been previously treated with a lower dose of mesalamine and those with more severe disease. The safety was comparable between the two groups.

Conclusions

The results suggest that treatment with pH-dependent release mesalamine at either 3.6 or 4.8 g/day was effective and safe for the induction of remission in patients with moderately active UC. However, the patients receiving mesalamine at 2.4 g/day but in whom the therapeutic effect is not sufficient and having more severe symptoms (UCDAI 9-10), benefit from higher doses of mesalamine compared to others.

Understanding fatigue among Japanese patients with inflammatory bowel disease: insights from international comparisons and meta-analysis: Makoto Tanaka, Momoko Takai, Sayaka Wakai, Kayoko Sakagami, Hiroaki Ito; Received September 13, 2024 Accepted November 17, 2024 Published online January 22, 2025; DOI: https://doi.org/10.5217/ir.2024.00145 [Epub ahead of print]

Background/Aims
Fatigue is a common symptom in patients with inflammatory bowel disease (IBD). The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale has demonstrated reliability and validity in assessing fatigue in patients with IBD and is used worldwide. This study aimed to examine the current state of fatigue among Japanese patients with IBD using the FACIT-F scale and to compare these findings with data from global studies through a systematic review.
Methods
Data from 488 patients with IBD treated at a specialized IBD clinic were analyzed. Patient characteristics, such as sex, age, disease duration, disease activity, FACIT-F scores, and sleep duration, were collected. A literature search identified 8 studies that met our inclusion criteria for an international comparison. A meta-analysis was performed on the Fatigue Subscale (FS) scores of FACIT-F to estimate the pooled mean.
Results
The mean FACIT-F (FS) score in this study was 39.9 ± 8.6. Four variables were significantly associated with fatigue: low Emotional Well-Being subscale scores, sleep duration < 6 hours, albumin level below the reference value, and being unmarried. The meta-analysis revealed that the pooled mean score was 40.2 (95% confidence interval, 39.5–40.9), and between-study heterogeneity was moderate (I² = 41%).
Conclusions
The FACIT-F (FS) scores and related factors in Japanese patients with IBD demonstrated a similar trend to those in other countries. These findings can be used to identify patients in need of support and to consider interventions for modifiable factors. This study will help promote international collaborative research.
