Vedolizumab: An Emerging Treatment Option for Pediatric Inflammatory Bowel Disease
Insights
Vedolizumab offers a safe and moderately effective treatment option for pediatric inflammatory bowel disease. Further research is needed to establish optimal dosing and long-term safety in children.
Area of Science:
- Gastroenterology
- Immunology
- Pediatric Medicine
Background:
- Vedolizumab, an α4β7-integrin antagonist, is FDA-approved for adult inflammatory bowel disease (IBD).
- Limited data exist for pediatric IBD patients, with current evidence from retrospective reviews and case series.
Purpose of the Study:
- To summarize existing literature on vedolizumab use in pediatric patients (< 18 years).
- To provide recommendations for vedolizumab treatment in pediatric IBD.
Main Methods:
- A narrative review of studies identified through a PubMed search (January 2014-December 2020).
- Keyword used: "vedolizumab".
Main Results:
- Vedolizumab demonstrates safety and moderate efficacy in pediatric IBD.
- Literature suggests weight-based dosing regimens for pediatric use.
- Long-term safety data are still limited.
Conclusions:
- Vedolizumab is a potential therapeutic option for refractory pediatric IBD.
- Prospective, randomized trials are necessary to optimize dosing and confirm long-term safety.
Abstract:
Vedolizumab is a humanized α4β7-integrin antagonist that is currently FDA-approved for adult inflammatory bowel disease. Limited evidence is available to guide use in pediatric patients, though off-label use is described in the form of retrospective reviews and case series. Collectively these publications begin to establish safety and efficacy data in pediatric patients < 18 years of age. Additionally, dosing regimens described in the literature serve to guide weight-based dosing, which is not established at this time. This narrative review aims to summarize the available literature and provide recommendations for vedolizumab use in the pediatric population. A literature search was performed in PubMed (January 2014-December 2020) using the keyword vedolizumab. Based on the available evidence, vedolizumab appears to be a safe and moderately effective agent for treatment of refractory pediatric inflammatory bowel disease. Prospective, randomized trials are warranted to optimize dosing regimens and to establish long-term safety.
