Background and study aims
Behçet’s disease (BD) is a rate and poorly understood condition that causes inflammation (swelling) throughout the body. The inflammation associate with BD can cause a wide range of symptoms, including genital and mouth ulcers, eye problems (which can lead to blindness), skin rashes and inflammation of the blood vessels, which increases a person’s risk of developing blood clots and stroke. The exact cause of BD is unknown however many believe it is an autoimmune disorder (in which the body’s immune system mistakenly attacks the body’s own, healthy tissue). Traditional treatments include corticosteroids (anti-inflammatory medicine) and immunosuppressant drugs (medications that reduce the activity of the immune system), but they can have unpleasant side effects. Biologic therapies are a newer type of medication, which target the biological processes involved in the process of inflammation more selectively. Recently, the biologic drugs infliximab and interferon alpha (aIFN) have been used successfully in treating BD however they are expensive (£16,000/year and £4,000/year, respectively), not always effective and there have been very few studies looking at their effectiveness. The Department of Health has recently commissioned three national Centres of Excellence for BD in London, Birmingham and Liverpool, with the remit to deliver care for the approximate 500 UK patients currently with this condition. The aim of this study is to compare the effectiveness of infliximab with aIFN at treating patients with BD.
Who can participate?
Adults with BD who are suitable to receive biological therapy.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are treated with infliximab. This is given through a drip (intravenous infusion) at the standard dose of 5mg/kg at the start of the study, week 2, week 6 and then every 8 weeks until the end of the study. Those in the second group are treated with aIRN. This is given as an injection under the skin (subcutaneous injection) starting at a dose of 3 million units one a day for 3 days, then 6 million units (for men who weight more than 80kg) or 4.5 million units (for women or men weighing less than 80kg) every day. This dose can be reduced down every 2-4 weeks if necessary to 3 million units twice a week over the course of the study. After 3 and 6 months of treatment, participants in both groups are assessed in order to find out if there has been any improvement to their condition.
What are the possible benefits and risks of participating?

Scientific title | BIO BEHÇET’S: Optimal utilisation of biologic drugs in Behçet’s Disease: a randomised controlled trial of infliximab vs alpha interferon, with genotyping and metabolomic profiling, towards a stratified medicines approach to treatment |
Study acronym | BIO BEHÇET’S |
Study objectives | The aim of the study is to create the evidence base to underpin clinically effective prescribing of the biologic drugs infliximab and alpha interferon for Behçet’s Disease. The objectives of the study are to: 1. Undertake a randomised controlled trial to compare IFX versus aIFN in patients with BD who are unresponsive to standard oral therapy 2. Examine whether IFNL3 and IFNL4 SNPs can predict response to aIFN and/or IFX in BD 3. Examine the potential for urine metabolomics to act as biomarker for drug response to IFX and/or aIFN in BD |

Health condition(s) or problem(s) studied | Behçet disease |
Intervention | Participants are randomly allocated to one of two groups. Group 1: Participants will receive infliximab at a standard dose of 5mg/kg at week 0, week 2 and week 6 as loading then every 8 weeks for the length of the trial. Group 2: Interferon alpha (Roferon) subcutaneous injection in tapering dose starting at 3 million units once daily for three days, then 6** million units once daily (male with body weight more than 80 kg) or 4.5 million units once daily (female, or male with weight less than 80 kg). Dose tapered down every 2-4 weeks according to defined clinical criteria to 3 million units twice a week, over the period of the trial. ** The six million units dose will only be administered to males of over 80 kg with major organ threatening disease (e.g., severe eye involvement). Males of less than 80kg or females will start with 4.5 million. |
Intervention type | Other |
Primary outcome measure | Disease severity is measured using the Behcet's disease activity index (BDAI) after 3 months of treatment. |
Secondary outcome measures | 1. Disease severity is measured using the Behcet's disease activity index (BDAI) after six months of treatment, 2. Significant improvement in organ involvement within the primary organ system that resulted in the decision to start a biologic agent and other organ systems assessed by: 2.1. Ocular: reduction in vitreous haze using the SUN consensus group grading scale and visual acuity change from baseline 2.2. Oral ulcer activity: change in ulcer severity score (USS) 2.3. Change in number of genital ulcers 2.4. Musculoskeletal: Likert pain score 3. Adverse events in each group 4. Reduction in dose of prednisolone (or equivalent glucocorticoid) at three months: a clinically meaningful reduction is considered to be 50% of baseline or dose of <15mg/day prednisolone 5. Reduction in dose of prednisolone (or equivalent glucocorticoid) at six months: a clinically meaningful reduction is considered to be 50% of baseline or dose of <7.5mg/day prednisolone 6. Quality of life is measured using EQ-5D and BD-QoL at baseline, 3 and 6 months 7. Disease activity is measured using the Physician’s Global Assessment of disease activity (a 7 point Likert Scale completed as part of (but assessed independently of) the BDAI) at 3 and 6 months |
