VedAryo® (Vedolizumab) Effectiveness and Safety Evaluation

AryoGen Pharmed Co.150 enrolled

Overview

The aim of this observational study is to evaluate Effectiveness and safety of VedAryo® (Vedolizumab) in male or female participants with clinical diagnosis of Inflammatory Bowel Disease. The main questions are aim to answer: 1. Is VedAryo® (Vedolizumab) effective in the treatment of Inflammatory Bowel Disease? 2. Is VedAryo® (Vedolizumab) safe in the treatment of Inflammatory Bowel Disease? In this study, there is no comparison group. Participants received VedAryo® (Vedolizumab)

This research was conducted as a phase IV, post-marketing, observational cohort study, in which VedAryo® (Vedolizumab) was prescribed as part of routine clinical practice, and no study-related intervention was introduced. The study aimed to evaluate the real-world effectiveness and safety of VedAryo® in Iranian patients diagnosed with Inflammatory Bowel Disease (IBD). The primary objective was to assess the effectiveness of VedAryo® based on clinical response, measured using the Mayo Scoring Index for ulcerative colitis and the Harvey-Bradshaw Index for Crohn's disease during the observation period. The secondary objective focused on safety, including the incidence of adverse events (AEs) and serious adverse events (SAEs) recorded over the 52-week observational follow-up.

Outcomes

Primary Outcomes

Percentage of Participants Achieving Clinical Response at Week 52

Clinical response is defined as a decrease from baseline in HBI score of ≥3 points in CD participants and a decrease from baseline in Mayo Score of ≥3 points, ≥30%, and either a decrease from baseline in the rectal bleeding sub score of ≥ 1 or a rectal bleeding sub score of 0 or 1 in UC participants.

Time frame: Baseline, week 52

Secondary Outcomes

Safety Assessment During 52 Weeks

Safety assessment, including the incidence of AEs. All AEs are classified based on the Medical Dictionary for Regulatory Activities (MedDRA Desktop Browser 4.0 Beta) terms as System Organ Class (SOC) and Preferred Term (PT). All the reported events are graded according to the Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). Moreover, seriousness of AEs is assessed according to International Council for Harmonisation (ICH-E2B) guidelines. The causality relation is assessed based on the World Health Organization (WHO) criteria.

Time frame: Up to 52 weeks

Percentage of Participants Achieving Clinical Remission at Week 52

Clinical remission is defined as a HBI score of \<5 points in CD participants and a Mayo Score of ≤2 points and no sub score of \>1 in UC participants.

Time frame: Baseline, week 52
