According to the Complaint, during the Class Period, defendants issued materially false and misleading statements to investors and/or failed to disclose that vadastuximab talirine, used as a cancer drug, holds a serious risk of fatal hepatotoxicity; that because of this, Seattle Genetics had exaggerated the use of vadastuximab talirine to treat acute myeloid leukemia; that as such, the Company’s public statements about Seattle Genetics’ business, operations, and prospects, were false and misleading and/or lacked a reasonable basis.

The Complaint further alleges that Seattle Genetics showed that the U.S. Food and Drug Administration had issued a clinical stop on initial stage trials of the Company's experimental cancer drug, vadastuximab talirine, to assess any potential outcome of hepatotoxicity. Seattle Genetics disclosed that six acute myeloid leukemia patients had liver toxicity and that four had died.

When this information was disclosed to the public, Seattle Genetics stock fell in value, causing investors serious harm.
