ITEM 7.01 — REGULATION FD DISCLOSURE

 

On March 11, 2008, Biotest AG announced that the Investigational New Drug (IND) application for BT-062 has been submitted to the US Food and Drug Administration (FDA) and that Biotest expects to begin clinical testing of this TAP compound in the first six months of 2008.  BT-062 is an anticancer compound in development by Biotest that comprises ImmunoGen’s cell-killing agent, DM4, linked to a Biotest antibody that binds to a target expressed on multiple myeloma and certain other types of cancers.

 

Biotest also disclosed that the FDA has granted orphan drug designation to BT-062. This designation can be conferred upon a promising therapeutic for the treatment of a rare but serious condition, and allows the compound to have market exclusivity without competition from generic equivalents  in the US for a period of up to seven years after marketing approval.
