55513-0079-XX Imlygic 100000000 UNIT/ML SUSP (AMGEN)

DESCRIPTION

Talimogene laherparepvec is a live, attenuated herpes simplex virus-1 for intralesional injection.  It has been genetically modified to replicate within tumors and produce the immune stimulatory protein GM-CSF.  This causes lysis of tumors followed by release of tumor-derived antigens.  Together with the virally-derived GM-CSF, this may promote an antitumor immune response, but the exact mechanism of action is not known.
