E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This is a research study looking at the effects of switching from one biosimilar drug (CT-P13), used to treat either Ulcerative Colitis (UC) or Crohn’s disease (CD) to another biosimilar drug (SB2), also used to treat UC or Crohn’s disease. CTP-13 (Inflectra, Remsima) and SB2 (Flixabi) are ‘biosimilars’ of Remicade, but work in the same way. The primary objective of this study is to evaluate the clinical outcome of switching a cohort of IBD patients from CT-P13 to SB2. Infliximab is a product originally produced and marketed by a single pharmaceutical company and given a brand name (Remicade). After a number of years, it is agreed that other companies can produce their own copies of Remicade. These copies are known as biosimilars and act in a similar way to the original product Remicade There are very tiny differences to the original product but we do not believe these affect how the drug works or it's safety and side effects. |
|
E.2.2 | Secondary objectives of the trial |
In addition the research will gather information to show the following: How UC or CD is managed after switching. How safe it is to switch from one Biosimilar drug to another How the immune system responds to this change Assess the quality of life after switching from CT-P13 (Inflectra, Remsima) to SB2 (Flixabi). Assess the patient life experiences after switching from CT-P13 (Inflectra, Remsima) to SB2 (Flixabi).

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measure is the clinical status as assessed by IBD control patient reported outcome measure, drug persistence laboratory measurements and appropriate validated disease activity scores. |

E.5.2 | Secondary end point(s) |
1. Incidence of Adverse Events, Serious Adverse Events, Adverse Events of Special Interest causally related to SB2 2. Immunogenicity as determined by presence of anti-drug antibodies (binding and /or circulating?) 3. Change from baseline to Week 24 and over time in patient reported outcomes or IBD PROM 4. Levels of laboratory inflammatory markers (faecal calprotectin, FBC, CRP and albumin) at baseline and over time during the study 5. Semi Structured interviews analysed using thematic analysis
