British Society for Rheumatology Biologics Register – RA

The BSRBR-RA study tracks the progress of people with rheumatoid arthritis (RA) who have been prescribed biologic (including biosimilar) and other targeted therapies in the UK to monitor the long-term safety of these drugs.


What is the study about? 

The BSRBR-RA is one of the largest prospective studies of patients receiving these drugs in the world, with over 20,000 patients registered in the study since it started in 2001. 

This epidemiological study is a unique collaboration between The University of Manchester, the British Society for Rheumatology and the pharmaceutical industry. All consultant rheumatologists in the UK who have prescribed anti-TNF, and other targeted therapies, have an opportunity to participate in the register, supported by allied health professionals. 

The Register captures data from rheumatologists and nurses who are looking after patients with RA, as well as asking patients themselves to complete questionnaires on how they are feeling. We also receive clinical data from national NHS databases (including NHS Digital) to enhance the data we collect. 

Why is the BSRBR-RA so important?  

When we start a new drug, we often ask ourselves if it is the right drug for me and will it cause me any harm or side effects. When most drugs are first approved for use, we actually have quite limited information on their safety. There will have been studies in animals to look at this, but these studies have their limitations as results can be different in humans. Most drugs will also undergo clinical trials, where their benefits and safety are also assessed, but sometimes these studies can be too small to detect rare safety problems and not all patients will be allowed to take part. Therefore, it is important that even after a drug can be prescribed by doctors we continue to monitor groups of patients receiving the drug for any unexpected harm. The BSRBR-RA has been set up specifically with this purpose and we have now followed over 30,000 patients receiving various biologic and other medications. Overall the results have been very reassuring but we must continue this effort as new drugs become available 

Conventional Synthetic Disease Modifying Anti-Rheumatic Drug (csDMARD) Cohort 

When biologic drugs were first available they represented a new option compared to conventional DMARDs such as methotrexate or sulphasalazine. Therefore when we set up the BSRBR-RA to look at side effects of biologics, we needed to know if these would be different to what we already knew about conventional DMARDs. Therefore, between 2001 and 2007 we recruited almost 4000 people receiving csDMARDs who had never received biologics. Many of our studies compare the rates of side effects or new health problems in people receiving biologics to people who are not. More recently, as more and more biologics become available, we undertake comparisons between different biologics types also

The BSRBR-RA is part of the Biologic Studies Group, led by Professor Kimme Hyrich at the University of Manchester. There are a number of other studies within the group, studying the safety and efficacy of biologic, biosimilar and other targeted therapies in musculoskeletal and dermatological conditions.

UK JIA Biologics Register.

The UK JIA Biologics Register is the collective name for two parallel studies which are coordinated at the University of Manchester:

These studies have been running for over 10 years. Children and young people with JIA who have received treatment with a biologic, biosimilar or other targeted new therapy are registered and followed-up over the long-term, to discover more about the safety and effectiveness of these treatments. Over 3500 participants have been recruited from 51 NHS Hospitals in the UK, and the data has resulted in 13 publications (as of August 2023) in peer-reviewed journals.

Established in 2007, BADBIR is a long-term prospective observational cohort study monitoring the safety and efficacy of biologic therapy in people with severe psoriasis. BADBIR has over 19,500 registrations from 164 centres.

BILAG-BR is a national study looking at the long-term safety and efficacy of biologic therapy in patients with lupus, compared with a group receiving standard immunosuppressive therapy. Established in 2010, BILAG now has 1,300 registrations from 59 centres.

CAPS recruits children who are newly diagnosed with juvenile idiopathic arthritis. It was established in 2001 and aims to discover ways to predict how patients will manage over the long term. 1,700 participants have been recruited from 7 centres across the UK
