What is Benlysta?
Benlysta: A Biologic Drug for Lupus
Benlysta is a biologic medication, meaning it is made from living cells, not chemicals. It contains the active ingredient belimumab, which is a monoclonal antibody that targets and reduces certain autoantibodies involved in the autoimmune response in lupus. This unique mechanism of action sets Benlysta apart as a valuable treatment option for those living with this chronic and complex autoimmune condition.
FDA Approval and Availability
Benlysta was first approved by the FDA in 2011 to treat adult patients with active systemic lupus erythematosus (SLE). In 2019, the FDA expanded the approval to include children ages 5 years and older with active SLE or active lupus nephritis. Benlysta is only available as a brand-name medication and does not have a generic or biosimilar equivalent.
Clinical studies have shown that Benlysta can effectively reduce disease activity and the risk of severe lupus flares when added to common lupus medications. Patients have reported improvements in symptoms affecting the muscles, joints, skin, mouth, kidneys, and immune system. Additionally, Benlysta has been found to help reduce the need for high-dose steroids, which can have significant side effects with long-term use.
Benlysta is available in a convenient pre-filled autoinjector for subcutaneous use, allowing for once-weekly administration. The autoinjector features several safety elements, such as an Inspection Window, Grey Stopper, Ring Cap, and Gold Needle Guard, to ensure proper and safe use. Proper storage, handling, and disposal guidelines must be followed to maintain the integrity and effectiveness of the medication.
How Does Benlysta Work?
Benlysta is an innovative medication that targets the underlying mechanisms of lupus by reducing the levels of a specific protein called B-lymphocyte stimulator (BLyS). This protein plays a crucial role in the production of autoantibodies, which are antibodies that mistakenly attack the body’s own tissues and organs, leading to the development of lupus symptoms.
By inhibiting the activity of BLyS, Benlysta helps to decrease the number of autoantibodies in the body, thereby minimizing the immune system’s destructive attack on the body’s own tissues. This targeted approach to lupus treatment helps to alleviate the underlying cause of the disease, rather than just managing the symptoms.
Mechanism of Action: Targeting Autoantibodies
The mechanism of action of Benlysta is centered around its ability to target and reduce the levels of autoantibodies, which are a hallmark of lupus. By binding to and neutralizing BLyS, Benlysta effectively inhibits the survival and proliferation of B cells, which are responsible for producing autoantibodies.
This reduction in autoantibody levels helps to minimize the immune system’s attack on the body’s own tissues and organs, which is the primary driver of lupus symptoms. Clinical studies have shown that Benlysta can lead to a 41% reduction in anti-double-stranded DNA antibody levels over 52 weeks, as well as decreases in other key B-cell subsets associated with lupus.
“Reductions in autoantibodies, total circulating B cells, and B-cell subsets, as well as increases in complement proteins, were consistent with findings from systemic lupus erythematosus (SLE) trials involving BENLYSTA.”
By targeting the underlying mechanism of action of lupus, Benlysta represents a significant advancement in the treatment of lupus, offering patients a new approach to managing this complex and challenging autoimmune disorder.
Benlysta for Systemic Lupus Erythematosus
Benlysta, a breakthrough biologic medication, has been approved by the US Food and Drug Administration (FDA) to treat active systemic lupus erythematosus (SLE) in adults and children 5 years and older. SLE is a chronic autoimmune condition that can cause inflammation in various parts of the body, including the skin, joints, and vital organs such as the kidneys, lungs, and brain. Symptoms of SLE may include rash, fever, joint pain, fatigue, and organ damage. Benlysta is used in combination with other standard lupus treatments to help manage the symptoms and progression of this debilitating disease.
Previously, children aged 5 years and older with active benlysta for SLE could only receive belimumab through an intravenous (IV) formulation, administered as a weight-based dose of 10 mg/kg, via a one-hour infusion every four weeks. However, the FDA has now approved a 200 mg subcutaneous route of administration of Benlysta for this pediatric population, offering a more convenient and accessible treatment option.
The approval of Benlysta for the pediatric systemic lupus erythematosus population is particularly significant, as children with SLE are more likely than adults to experience problems with vital organs, especially the kidneys. Benlysta is the first and only approved biologic for both SLE and lupus nephritis (LN) in more than 50 years, including for the pediatric population, providing a much-needed treatment option for this vulnerable group.

Benlysta injection for Lupus Nephritis
Benlysta, a biologic medication, is approved not only for the treatment of systemic lupus erythematosus (SLE) but also for managing active lupus nephritis, a complication where the autoimmune disease affects the kidneys. Lupus nephritis is characterized by inflammation and damage to the kidneys, leading to symptoms like blood in the urine, swelling, high blood pressure, and protein in the urine.
By targeting the underlying autoimmune process, Benlysta can help control the kidney inflammation and prevent further autoimmune kidney disease in people with lupus nephritis. Benlysta is available as an intravenous (IV) infusion or a subcutaneous injection, and the specific dosage and administration route are determined based on the individual patient’s needs and the severity of their condition.
Treating Kidney Inflammation in Lupus
Benlysta’s approval for lupus nephritis is a significant development, as it provides an additional treatment option for this serious complication of lupus. By addressing the root cause of the inflammation, Benlysta can help preserve kidney function and improve the overall health and well-being of patients with benlysta for lupus nephritis.
“Benlysta is an important treatment option for patients with active lupus nephritis, as it can help manage the autoimmune-driven inflammation and prevent further kidney damage.”
Patients with lupus nephritis are advised to work closely with their healthcare providers to determine the most appropriate treatment plan, which may include Benlysta in combination with other medications or therapies. Regular monitoring and follow-up are crucial to ensuring the best possible outcomes for those living with this challenging condition.
Dosage and Administration
Benlysta, a biologic drug for treating systemic lupus erythematosus (SLE), is available in two formulations: an intravenous (IV) infusion and a subcutaneous injection.
