Plain English summary of protocol
Background and study aims
Juvenile idiopathic arthritis (JIA) is a form of arthritis that develops in children under 16. The cause of the disease is unknown. Symptoms include inflammation, pain and swelling of the joints. There are a number of forms of JIA, including oligoarticular JIA, polyarticular JIA and systemic onset JIA. Eye problems are common and include uveitis, a condition where there is swelling of the middle layer of the eye. Symptoms of uveitis include painful, red eyes, blurred vision, floaters and loss of peripheral vision. It is not a common condition but is still a leading cause of visual impairment in the UK. Here, we want to conduct a study to test whether adding tocilizumab to methotrexate (MTX) treatment will prevent the serious complications, such as glaucoma, cataracts and detached retina that can occur from uncontrolled uveitis in children with JIA. We wish to test the response rate to tocilizumab in combination with MTX and determine whether further research into this treatment for severe, refractory uveitis should be done.
Who can participate?
Children aged between 2-18 years with JIA and severe uveitis who have not responded or are not getting better on anti -TNF therapy (drugs such as adalimumab and infliximab)
What does the study involve?
All children taking part in this study are given tocilizumab injections every 2 weeks or 3 weeks as well as MTX treatment. The dosage for each child is calculated according to their body weight. Response to the treatment is reviewed after 3 months.
What are the possible benefits and risks of participating?
The NHS and its patients would benefit from this trial because patients will be the first worldwide to have access to this novel biological agent within the context of a combined hospital clinic with ophthalmologists and paediatric rheumatologists. Tocilizumab may affect the immune system (your body’s natural defences) and you may be more likely to get infections. Tocilizumab can also increase cholesterol levels, which will be monitored during the course of the study at each visit. Some other common side effects of Tocilizumab are
a cough or a sore throat, a blocked or runny nose, a headache or dizziness, mouth ulcers, conjunctivitis, high blood pressure, weight gain or swollen ankles, skin rashes, infections or itching, stomach irritation (gastritis), inflammation around the drip/ injection site.
Where is the study run from?
Six NHS hospitals in the UK
When is the study starting and how long is it expected to run for?
August 2015 to January 2018
Who is funding the study?
Arthritis Research UK
Who is the main contact?

| Scientific title | A phase II trial of tocilizumab in anti-TNF refractory patients with JIA associated uveitis |
| Study acronym | APTITUDE |
| Study objectives | This study aims to test whether adding tocilizumab to methotrexate treatment for children with severe uveitis will enable us to prevent the serious complications that can occur from uncontrolled uveitis in children with juvenile idiopathic arthritis (JIA). |
| Ethics approval(s) | NRES Committee London - South East, ref: 15/LO/0771 |
| Health condition(s) or problem(s) studied | Topic: Children, Ophthalmology, Musculoskeletal disorders; Subtopic: All Diagnoses, Eye (all Subtopics), Musculoskeletal (all Subtopics); Disease: All Diseases, Non-inflammatory Joint Disorders, Other |
| Intervention | All participants will receive tocilizumab injections every 2 weeks or every 3 weeks (dependent upon weight) of tocilizumab alongside methotrexate (MTX) treatment. The dosage will be calculated based on patient body weight. Study Entry : Registration only |
| Intervention type | Drug |
| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | Tocilizumab |
| Primary outcome measure(s) |
The primary endpoint is response to treatment. Response to treatment is defined as per SUN criteria as a 2 step decrease in the level of inflammation (anterior chamber cells) or decrease to zero between baseline (prior to trial treatment initiation) and after 12 weeks of treatment. |
| Key secondary outcome measure(s) |
1. Safety, tolerability and compliance |
