Switching From Reference Infliximab to Biosimilar CT-P13 Did Not Change Quality of Life in Stable Inflammatory Bowel Disease Patients.

Background: Quality of life (QoL) data for patients with inflammatory bowel disease switched from the reference infliximab to biosimilar CT-P13 is lacking. This study aims to demonstrate noninferiority for QoL and efficacy after switching.

Methods: OoL and clinical efficacy were measured prior to and after 2, 4, and 6 CT-P13 infusions.

Serum concentrations after switching from originator infliximab to the biosimilar CT-P13 in patients with quiescent inflammatory bowel disease (SECURE): an open-label, multicentre, phase 4 non-inferiority trial.

Background: Biological treatment of chronic inflammatory diseases has improved patient outcomes but increased health-care costs. Switching patients from originator infliximab to a biosimilar can reduce costs, but prospective data about pharmacokinetics and potential immunogenicity are scarce. We aimed to show that infliximab serum concentrations with biosimilar CT-P13 are non-inferior to those with originator infliximab after switching from originator infliximab in patients with inflammatory bowel disease.

Blood flow in the hands of a predefined homogeneous systemic sclerosis population: the presence of digital ulcers and the improvement with bosentan.

Objectives: The aim of the study was to examine the effect of bosentan on blood flow in the hand in a subset of patients who had reduced blood flow relative to healthy subjects. Additionally, the relationship between blood flow in the hands of SSc patients and the presence of digital ulcers (DUs) was assessed.

Methods: SSc patients with a recent history of DUs and healthy subjects were included.
