Active Biotech Advances 57-57 Project


In addition, a number of biological markers will be monitored to determine the effect of 57-57 on disease progression.
This multi-centre dose-escalation study is being conducted at three hospitals in Sweden - the Karolinska University Hospital in Stockholm, the Uppsala University Hospital in Uppsala, and the Lund University Hospital in Lund. Dr. Anders Bengtsson of the Lund University Hospital is the principal investigator for the trial.
SLE is a chronic rheumatic disease that affects joints, muscles and other parts of the body. An estimated 500,000 Americans have been diagnosed with SLE; however, surveys indicate that the prevalence may be much higher.
Phase II/III clinical trials of 57-57 are planned for 2007.
As previously reported, Active Biotech completed the first Phase I study of 57-57 earlier this year. That study, which examined the safety and pharmacokinetics of the drug in 30 healthy volunteers, was conducted at the Karolinska University Hospital in Stockholm. Results from the study showed that 57-57 was very well tolerated in all of the studied dose levels, both as single and repeated doses, and it is well suitable to be administered orally as a daily treatment.
