LYNBROOK, N.Y., June 1, 2011 /PRNewswire/ -- BioSpecifics Technologies Corp. (NASDAQ: BSTC ), a biopharmaceutical company developing first in class collagenase-based products, today announced that positive data for XIAPEX® (clostridial collagenase histolyticum for injection) were presented at the XVIth Annual Federation of European Societies for Surgery of the Hand (FESSH) Congress which took place in Oslo, Norway at the Oslo Congress Centre on May 26-28, 2011.

Specifically, after XIAPEX treatment for metacarpophalangeal, or MP, joints in previously operated hands, the mean decrease in fixed flexion contracture was 75 +/- 2.8% while patients treated in hands that h
