Systemic Lupus Erythematosus
Our commitment to the lupus community and advancing the scientific understanding of lupus
Our vision for systemic lupus erythematosus
Systemic lupus erythematosus (SLE) is a chronic immune-driven disease in which the body’s immune system attacks healthy tissue in any part of the body.1 It’s experienced differently by each person and can cause a wide range of debilitating symptoms, including skin rash, joint pain, swelling and fevers.2 There hasn’t been a new medicine approved for SLE in over a decade, and the significant physical, emotional and socio-economic burden remains high for people living with the disease.3
Our researchers are working to unlock the science of the immune system to address the significant unmet needs in lupus. By highlighting the experiences from people with SLE and investigating the underlying drivers of this complex disease, we aim to bring scientific advancements to the lupus community and challenge the boundaries they’ve had to accept for too long.
Lupus affects each person differently and can be unpredictable. Hear from people with systemic lupus erythematosus (SLE) on how the disease has impacted their lives since diagnosis, and their hope for scientific advancements in the field.
Living with lupus
I was diagnosed with lupus when I was 23 and have been a Lupus Warrior for 17 years. At different points in my life, I have experienced various symptoms, including skin rash, joint pain and extreme fatigue, in addition to the emotional journey that's attached to the condition. At times these can be debilitating and it’s like a rollercoaster. There's highs, there's lows. But I’m more hopeful today than ever that scientific progress is being made to help improve the lives of people like me who are living with lupus.
Addressing unmet needs in the lupus community
Systemic lupus erythematosus is more common among those of African, Asian or Hispanic ethnicities.4 It is also estimated that 90 percent of people diagnosed with SLE are women.1
New treatments are needed to address the significant unmet medical needs faced by those living with lupus and their healthcare professionals. Patients still often have inadequate disease control, poor health-related quality of life outcomes and related health conditions. Many people with SLE rely on prolonged use of oral corticosteroids, which can be helpful in addressing increases in disease activity but can also increase the risk of organ damage and other significant side effects.5,6,7,8
Organ damage and more severe disease characteristics often require more costly care to manage.9 Across multiple countries, we found that earlier diagnosis and treatment are crucial to lowering the financial burden of SLE by reducing the risk of disease progression and flare frequency, protecting from organ damage and improving quality of life.10,11,12,13,14
We are following the science, through decades of research and an evolved understanding of the underlying drivers of this disease to address key areas of unmet needs in SLE.
Unlocking the science of SLE
For people living with systemic lupus erythematosus, the immune system inappropriately attacks healthy tissue in the body.1 SLE disease activity involves B, T and dendritic cells, as well as inflammatory cytokines such as type 1 interferons (IFN-1), IL-6 and B-cell activating factor. Cytokines are molecules that act as immune signallers, regulating processes along immune pathways that coordinate the overall immune response. This results in an over-activated immune response, which along with the creation of autoantibodies (antibodies formed in response to the body’s own tissues), can lead to injury, inflammation and long-term organ damage. Up to 60-80% of adults with SLE may have an elevated IFN-1 gene signature, which can be associated with increased disease severity.15,16,17,18,19,20
By understanding the role key inflammatory cytokines play in that cascade, we can begin to further unlock the complex nature of this challenging disease.
