Re-Routing Infliximab Therapy: Subcutaneous Infliximab Opens a Path Towards Greater Convenience and Clinical Benefit.
|
| Abstract |
Subcutaneous infliximab recently received approval for the treatment of various immune-mediated inflammatory diseases in Europe, following pivotal clinical trials in patients with rheumatoid arthritis and inflammatory bowel disease. Subcutaneous infliximab demonstrated an improved pharmacokinetic profile compared with intravenous infliximab: the more stable exposure and increased systemic drug concentrations mean it has been cited as a biobetter. Alongside the pharmacokinetic advantages, potential benefits for efficacy, immunogenicity, and health-related quality-of-life outcomes have been suggested with subcutaneous infliximab. During the coronavirus disease 2019 pandemic, the benefits of subcutaneous over intravenous therapies became apparent: switching from intravenous to subcutaneous infliximab reduced the hospital visit-related healthcare resource burden and potential viral transmission. Clinical advantages observed in pivotal trials are also being seen in the real world. Accumulating experience from four European countries (the UK, Spain, France, and Germany) in patients with rheumatic diseases and inflammatory bowel disease supports clinical trial findings that subcutaneous infliximab is well tolerated, increases serum drug concentrations, and offers maintained or improved efficacy outcomes for patients switching from intravenous infliximab. Initial evidence is emerging with subcutaneous infliximab treatment after intravenous infliximab failure. High patient satisfaction and pharmacoeconomic benefits have also been reported with subcutaneous infliximab. Treatments aligned with patient preferences for the flexibility and convenience of at-home subcutaneous administration could boost adherence and treatment outcomes. Altogether, findings suggest that switching from intravenous to subcutaneous infliximab could be advantageous, and healthcare professionals should be prepared to discuss supporting data as part of shared decision making during patient consultations.
