CT-P13 subcutaneous infliximab in gastroenterology and rheumatology

Abstract

The drug infliximab has been a key milestone in the treatment of inflammatory conditions such as Crohn's disease, ulcerative colitis, rheumatoid arthritis and the seronegative spondyloarthritides. Biosimilar drugs followed the originator, further improving access and diversity of therapy choice. Subcutaneous infliximab (CT-P13) holds potential for greater patient flexibility by self administration, reducing travel and hospital attendance for infusion, particularly relevant at a time of pandemic. We highlight the pharmacodynamic and pharmacokinetic basis of the subcutaneous device, clinical trials in rheumatology and gastroenterology and consider the safety and cost implications. Real-world switching data is required to confirm the efficacy data from clinical trials given the reduction in dosing flexibility compared with intravenous therapy.
