Systematic review with meta-analysis of the effectiveness of subcutaneous biologics versus intravenous biologics in inflammatory bowel diseases

Biologic therapies are commonly used for inflammatory bowel disease (IBD) patients. Multiple biologic medicines can now be given both intravenously and subcutaneously. The different administration routes present provide different advantages regarding dose escalation, healthcare resource utilisation, pharmacokinetics, convenience and safety. Comparator effectiveness studies between intravenous and subcutaneous administration are lacking.
