Plain English summary of protocol

Background and study aims
This study is looking at the effects of switching from intravenous (administered into a vein in the hospital) infliximab to infliximab administered subcutaneously (injection under the skin administered at home). The subcutaneous infliximab (commercially known as Remsima) and intravenous infliximab are highly similar.

This study aims to explore the following:
1. Does the clinical status of inflammatory bowel disease (Crohn's disease or ulcerative colitis) or inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis) patients stay the same after switching the route of infliximab administration?
2. How safe and is it to switch from intravenous infliximab to infliximab self-administered subcutaneously?
3. What are the views and experiences of patients who switch from intravenous infliximab to infliximab self-administered subcutaneously?
4. Does the quality of life change for patients switching the route of infliximab administration?

Who can participate?
Patients aged 18 or over with inflammatory bowel disease (Crohn's disease or ulcerative colitis) or inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis) being treated with intravenous infliximab

What does the study involve?
This study aims to follow the normal standard of care as much as possible. Participants will be required to attend up to 4 hospital visits at University Hospital Southampton NHS Foundation Trust (UHS) for trial assessments which will, as far as possible, mirror normal clinical care. These would replace their normal visits for infusions. Participants will be trained on how to self-inject the study drug and will administer this themselves at home every 2 weeks. The study will last for 24 weeks, after which participants will return to their normal clinical care.

What are the possible benefits and risks of participating?
It is not known if participants will personally benefit from this research, however, it is hoped that this research will show that it is safe and tolerable to switch to the subcutaneous route. One possible benefit is that participants will have fewer visits to the hospital over the time they are in the study.

Most of the treatments and assessments participants will receive will be standard of care (i.e. participants would have received the treatments and assessments anyway even if they weren’t involved in the study). There will be several extra questionnaires to complete as part of the study.

The only additional risk beyond the risks of receiving infliximab via the intravenous route could be discomfort or reactions around the subcutaneous injection site. These can include redness, pain, itching, swelling, hardness, bleeding, bruising, cold sensation, irritation, tingling sensation, ulcer, hives, rash, and scab on the skin of the injection site. Most of these reactions are mild and resolve relatively quickly on their own.

The most common risks of receiving infliximab via either the subcutaneous or intravenous routes include viral infections (such as flu or cold sores), headache, upper-respiratory-tract infection (colds), sinusitis (inflammation of the sinuses), nausea (feeling sick), abdominal pain (stomach ache), and injection site-related reactions and pain.

With any infliximab medication, there is a risk of developing an allergic reaction. If a serious reaction occurs, treatment will be given to alleviate the symptoms and further treatment with infliximab will be reviewed. In previous clinical trials, delayed hypersensitivity reactions (unwanted reactions produced by the normal immune system) have been reported so participants will be advised to seek immediate medical advice if they experience any delayed adverse effects.

3. Immunogenicity to infliximab
4. The presence of inflammatory markers over time
5. Subject experience and treatment satisfaction over time
Ethics approval(s)Approved 14/12/2020, East Midlands - Nottingham 2 Research Ethics Committee (The Old Chapel, Royal Standard Place, Nottingham, NG1 6FS; +44 (0)2071048103;nottingham2.rec@hra.nhs.uk) ref: 20/EM/0285
Health condition(s) or problem(s) studiedUlcerative colitis, crohn's disease, rheumatoid arthritis, psoriatic arthritis, or ankylosis spondylitis
InterventionThis study will aim to recruit participants with inflammatory bowel disease or inflammatory arthritis who are being treated with intravenous (IV) infliximab as part of their routine clinical care. Participants will be switched from IV infliximab to a self-administered subcutaneous injection of 120 mg/ml infliximab biosimilar (CT-P13) every 2 weeks for a duration of 24 weeks. The first subcutaneous injection will be given when the patient is scheduled to receive their next dose of IV infliximab. Training will be provided and the first dose will be administered under supervision. Thereafter subcutaneous CT-P13 will be self-administered every 2 weeks by the subject in their home.

Potential participants will be sent the patient information sheet by post, email, or another contact with the clinical or research team up to 24 h prior to enrolment. The patients will be given adequate time to consider the trial information before being asked to sign the informed consent form. Patients who do not wish to take part in the study will be given the opportunity to take part in the semi-structured qualitative interviews to capture their reasons for not participating.

Participants will be assessed at a screening visit and 3 further visits.

Baseline (screening) visit
At the screening visit, the investigator will go through the inclusion and exclusion criteria and ensure that the patient is eligible to proceed.
The patient will be fully informed of all aspects of the trial, the potential risks, and their obligations. The aims of the study and all tests to be carried out will be explained. The patient will be given the opportunity to ask any questions that they have and will then have time to consider whether to participate. If they do decide to participate, they will sign and date the consent form and will be given a copy to take away. The original will be kept in the site file and stored as source documentation. These forms will also be signed and dated by the Investigator.

The assessments at the baseline visit will include:
1. Medical history, listing any concomitant medications, establishing a baseline of adverse events, and review of any contraindications
2. Tests for active and inactive tuberculosis, hepatitis B virus, hepatitis C, and varicella, if previous test results are not available
3. Pregnancy tests for women of childbearing potential
4. Laboratory tests including haemoglobin, platelets, albumin, and C-reactive protein (CRP)
5. Completion of disease scores (disease-specific). For Crohn's disease patients, the Modified Harvey-Bradshaw Index (mHBI) and IBD Control (IBD-CTRL) Patient-Reported Outcome Measure (PROM). For ulcerative colitis patients, the Simple Clinical Colitis Activity Index (SCCAI) (UC) and IBD Control (IBD-CTRL) Patient Reported Outcome Measure (PROM). For rheumatoid arthritis and psoriatic arthritis patient’s, the Clinical Disease Activity Index/Simplified Disease Activity Index (CDAI/SDAI) and Disease Activity Score from 28 joints (DAS28). For ankylosis spondylitis patients, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI).
6. Completion of Health-Related Quality of Life measures. For Crohn's disease and ulcerative colitis patients, the Short Form 36 Health Survey Questionnaire (SF-36) and IBD Control (IBD-CTRL) Patient-Reported Outcome Measure (PROM). For rheumatoid arthritis, psoriatic arthritis and ankylosis spondylitis patients, the SF-36, pain visual analogue score (VAS), and Health Assessment Questionnaire Disability Index (HAQ-DI), and one of the following, as appropriate: Bath Ankylosing Spondylitis Functional Index (BASFI), Psoriatic Arthritis Impact of Disease (PsAID) questionnaire, or Rheumatoid Arthritis Impact of Disease (RAID) questionnaire .
7. Qualitative assessments using semi-structured interviews

If the patient is eligible to continue onto the study, they will be enrolled into the inflammatory bowel disease or inflammatory arthritis cohort. Participants will be allocated a subject study ID number and will receive a participant dosing and questionnaire diary with the relevant research team's contact details. Participants will be trained on injection requirements at this visit. A letter will be sent to the GP for each participant informing them of the clinical study.

In order to minimise the number of potential visits to the hospital, the baseline visit and study visit 1 may take place on the same day. Visit 1 will involve the first subcutaneous CT-P13 administration as well as the following assessments:
1. Clinical review
2. Routine laboratory tests
3. Anti-Drug Antibody and drug trough level measurements
4. A stool sample will also be collected at this visit for faecal calprotectin for the inflammatory bowel disease cohort
5. Pregnancy test for women of childbearing potential
6. Completion of disease scores (disease-specific) as at the baseline visit
7. Completion of Health-Related Quality of Life measures as at the baseline visit
8. Completion of Treatment Satisfaction questionnaire of Medication (these will be completed every 2 weeks)
9. Completion of VAS pain scores (these will be completed after each administration of injection)
10. Drug accountability/compliance
11. Incidence of adverse events
At this visit, the study team will provide the CT-P13 medication to participants, and re-training for subcutaneous injections will be provided if necessary. The first dose will be administered under supervision.

Visit 2 will take place after 12 weeks and involve the following assessments:
1. Clinical review
2. Routine laboratory tests
3. Anti-Drug Antibody and drug trough level measurements
4. Pregnancy test for women of childbearing potential
5. Completion of disease scores (disease-specific) as at the baseline visit
6. Completion of Health-Related Quality of Life measures as at the baseline visit
7. Completion of Treatment Satisfaction questionnaire of Medication (these will be completed every 2 weeks)
8. Completion of VAS pain scores (these will be completed after each administration of injection)
9. Drug accountability/compliance (using the dosing diary)
10. Incidence of adverse events
At this visit, the study team will provide further CT-P13 medication to participants.

Between weeks 12 and 24, there is the option of participating in a semi-structured interview exploring the participant's experience of switching from IV Infliximab to subcutaneous Infliximab.


Visit 3, the end of study visit, will take place after 24 weeks and involve the following assessments:
1. Clinical review
2. Routine laboratory tests
3. Anti-Drug Antibody and drug trough level measurements
4. A stool sample will also be collected at this visit for faecal calprotectin for the inflammatory bowel disease cohort
6. Completion of disease scores (disease-specific) as at the baseline visit
7. Completion of Health-Related Quality of Life measures as at the baseline visit
8. Completion of Treatment Satisfaction questionnaire of Medication
9. Completion of VAS pain scores
10. Drug accountability/compliance
11. Incidence of adverse events
At this visit, the study team will collect completed diary dosing cards and questionnaires as well as any unused pens or syringes.

Patient withdrawal:
Subjects may withdraw from the study at any time and are not obliged to give their reasons for doing so. The investigator may withdraw the subjects at their discretion or due to any adverse events. An end of study visit will be completed if a withdrawal occurs.

Semi-structured Interviews with Participants:
The study team will conduct semi-structured interviews on a purposive sample of patients in a setting of their choice, either in person or over the phone. Interviews will take place at times convenient to the interviewees (likely to be at a study visit) and will last no longer than 1 h. An interview guide will be constructed based on key issues identified from the literature and drawing on our combined clinical experience. This guide will be piloted with a small sample of patients and revised if necessary. Subject interviews will also draw on individual subject responses in the outcome measures completed at regular time points throughout the period of the study. Interviews will be audio-recorded using a digital recorder and fully transcribed.

Interview data will be analysed using thematic analysis to identify key themes and issues which characterise the patient and clinical staff experience. Braun and Clarke’s (2006) six steps of thematic analysis will be used: data familiarisation, generating initial codes, themes searching, reviewing themes, defining and naming the themes, and producing the report.

In addition, the study team will conduct qualitative interviews with participants who have been approached but declined to participate in the study from the outset. Only a selection of these participants will be approached to take part in the interview only process in order to explore reasons and potential barriers. These will be conducted over the phone. Participants will also be required to verbally consent to take part in the interview only process over the phone. As with the interviews conducted on trial participants, interview data will be analysed using thematic analysis to identify key themes and issues.
