Active Biotech's Phase I Study of SLE project 57-57 concluded

The first clinical study with Active Biotech's candidate drug 57-57 against SLE, Systemic Lupus Erythematosus, has been successfully concluded.

The Phase I study, which comprised a total of 30 healthy volunteers, was performed in cooperation with the Phase I unit at the Karolinska University Hospital in Stockholm.

The results show that 57-57 is very well tolerated in all of the studied dose levels; both as single and repeated dose, and that it is well suitable to be given as an oral, daily treatment.
