LUND, Sweden, June 18, 2007-Active Biotech (OMX Nordic: ACTI) has presented pre-clinical data for the 57-57 project at the 8th World Congress on Inflammation (www.inflammation2007.dk) held in Copenhagen June 16-20*.

"The results strengthen the further clinical development of 57-57 for the treatment of SLE and show the possibility to reduce the use of steroids. Phase II clinical trials are planned to be initiated before year end", commented Sven Andréasson, President & CEO Active Biotech.

The new pre-clinical data presented show that 57-57, in an experimental model of the disease systemic lupus erythematosus (SLE), can replace prednisolone, an anti-inflammatory corticosteroid widely used in a broad range of different inflammatory diseases, among them SLE.

Several symptoms commonly associated with SLE, such as hematuria (blood in the urine) and glomerulonephritis (inflammation in the kidneys) could be significantly reduced when combining 57-57 and a lower dose of steroid.

About SLE and 57-57 Systematic Lupus Erythematosus (SLE) is a disease of the connective tissues that can cause inflammation and damage to the connective tissue in many different organs. The disease, which progresses in "flare-ups" interspersed with relatively symptom-free periods, primarily affects women of child-bearing age. Progress and symptoms of the disease vary widely, depending on the organs affected. Without treatment, SLE can be life-threatening. Active Biotech has decided to estimate the market conservatively at 1,000,000 patients in the US and Europe. The market potential for the SLE indication is estimated at approximately USD 6 billion.
