Section 8-Other Events

Item 8.01 Other Events.

     On December 14, 2004, BioTime submitted a request to withdraw its application to the Swedish Medical Products Agency (“SMPA”) for approval to market Hextend in Sweden. When BioTime filed the application in August 2000, it hoped to obtain approval based upon its U.S. clinical trials of Hextend, which compared Hextend to 6% hetastarch in saline solution. BioTime did not intend to do any additional clinical studies for SMPA approval. However, the Hextend formulation includes a high molecular weight, high degree of substitution hetastarch, and the SMPA has only approved plasma volume expanders that contain lower molecular weight, lower degree of substitution starch. Subsequently, the SMPA asked BioTime for clinical data comparing Hextend with a plasma volume expander containing a lower molecular weight, lower degree of substitution starch already approved in Sweden. BioTime has determined that conducting a large scale clinical trial would not be economical for the purpose of obtaining regulatory approval in Sweden, and elected to request the withdrawal of its application.

     BioTime is also developing PentaLyte, a plasma volume expander that has a formulation similar to Hextend but uses a starch that has a molecular weight and degree of substitution similar to that of a starch used in a product approved for use in Sweden. BioTime is developing PentaLyte to complement Hextend in its product line in order to provide physicians with a choice of products formulated with starches having different molecular weights and degrees of substitution. However, BioTime is first beginning its U.S. Phase II clinical trial of PentaLyte and does not yet have the kind of clinical data that would be needed to obtain approval of PentaLyte in Sweden at this time.
