Plain English Summary
Background and study aims
In autoimmune diseases such as systemic lupus erythematosus (SLE), the immune system has lost the ability to discriminate between body-own ('self') and foreign proteins. In consequence, antibodies are generated to attack 'self'-proteins and form immune complexes which continuously activate the immune system through binding to specific immune cells in the body. As a result, the activated immune system can lead to severe organ damage, including the kidney. This study investigates a new treatment for preventing and/ or ameliorating SLE in patients with or without a history of lupus nephritis ((prolonged inflammation of kidneys). Previous investigations in SLE animal studies suggest that the drug SM101 competes with the immune complex binding and has the potential to prevent organ damage caused by the activated immune system. The aim of this study is to investigate the safety and efficacy of SM101 in the treatment of SLE patients with or without a history of lupus nephritis and a SELENA-SLEDAI score of ≥ 6.
Who can participate?
SLE patients with or without a history of lupus nephritis and a SELENA-SLEDAI score of ≥ 6.
What does the study involve?
The study includes 10 visits for non-pharmacokinetic (PK) patients and 13 visits for PK patients. There is a 3 weeks screening period, a 4 weeks treatment and a 5 months follow-up period.
What are the possible benefits and risks of participating?
Previous studies suggest that SM101 appears to be generally well tolerated and safe. However, some patients may experience some adverse reactions which have not been reported so far. The side effects may be a minor inconvenience or could be severe. Patients will be watched closely for any side effects, and the drug will be stopped if serious side effects develop.
Where is the study run from?
Thirty clinical trial sites for the SMILE study are located in Australia, Belgium, Czech Republic, France, Germany, Italy, Netherlands, Poland, Spain and UK.
When is the study starting and how long is it expected to run for?
The first enrolment of patients is planned for August 2011 with a recruitment period of 14 months until October 2012.

| Scientific title | Phase IIa, 2:2:1 randomised, double-blind, placebo-controlled, parallel group, multi-centre clinical trial to investigate the safety, efficacy and pharmacokinetics of recombinant human soluble Fc-gamma receptor IIb (SM101) for intravenous application in the treatment of systemic lupus erythematosus (SLE) patients with or without a history of lupus nephritis |
| Study acronym | SMILE |
| Study hypothesis | The human soluble Fcγ receptor SM101 competes with the binding of systemic lupus erythematosus (SLE)-specific immune complexes to effector cells and therefore interrupts the immunological cascade leading to inflammation and organ damage. |
| Ethics approval(s) | Approval pending as of 30/06/2011 |
