Details and patient eligibility
About
This two year study will evaluate the effects of giving belimumab (Benlysta) to patients with Early Lupus. Early lupus is a diagnosis of lupus within 2 years. Subjects will be randomized to receive belimumab or placebo during the first year. During the second year, subjects who were randomized to belimumab will be rerandomized to continue to receive belimumab or to receive placebo. The study will look at clinical effects as well as effects on the immune system.
Full description
This protocol proposes that early treatment of Systemic Lupus Erythematous (SLE) may prevent tissue damage and may even lead to long-term remission of disease. This concept is supported by reports of SLE-associated autoimmunity that are detected serologically many years prior to any constitutional symptoms or specific tissue inflammation and immune dysregulation precedes the development of clinically apparent SLE. Belimumab (Benlysta) is an FDA approved medication and is a monoclonal antibody directed against B cell-activating factor (BAFF)/ B Lymphocyte Stimulator (BLyS). B cells maturing in environments with high BAFF levels are more likely to be autoreactive B cells. This is a double-blind placebo controlled trial of belimumab, in patients with early lupus, ie lupus diagnosed within 2 years. Thirty subjects will be randomized (2:1) to receive subcutaneous belimumab weekly or placebo. After a year of treatment, subjects receiving belimumab will be rerandomized (1:1) to receive belimumab or placebo. The primary outcome is B cell autoreactivity. Clinical efficacy including disease activity, flares, attainment of low disease activity or remission as well as surrogate cardiovascular biomarkers will also be assessed.

- Receipt of a live vaccine within 30 days prior to baseline or concurrently with belimumab
- Have a history of an anaphylactic reaction to parenteral administration of contrast agents, human or murine proteins or monoclonal antibodies

- Significant cardiac or pulmonary disease (including obstructive pulmonary disease)
- Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or render the patient at high risk from treatment complications
- History of malignant neoplasm within the last 5 years with the exception of adequately treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix
- Evidence of serious suicide risk including any history of suicidal behaviour in the last 6 months and/or any suicidal ideation in the last 2 months or who in the investigator's judgment, pose a significant suicide risk
