Amgen Presents New Data From Phase 3 Study Of Talimogene Laherparepvec

AMGEN (NASDAQ: AMGN) today announced additional results from a pivotal Phase 3 trial evaluating talimogene laherparepvec in patients with unresected stage IIIB, IIIC or IV melanoma compared to granulocyte-macrophage colony-stimulating factor (GM-CSF). Results of the study's key secondary endpoints will be presented during a poster session at the 17th ECCO - 38th ESMO - 32nd ESTRO European Cancer Congress in Amsterdam (Abstract No. 3733 / P479). New data presented include investigator assessments of response: the durable response rate (DRR) was 19 percent with talimogene laherparepvec as compared with one percent for the GM-CSF arm, and the objective response rate was 31 percent versus six percent in the GM-CSF arm. Overall there was a high degree of correlation between the independent and investigator assessments. Key secondary endpoints include time to response and duration of response by independent assessment. The median time to response was 4.1 months (range 1.2 months - 16.7 months). The duration of response was longer in the talimogene laherparepvec arm, with an estimated 68 percent of talimogene laherparepvec responders achieving responses lasting at least nine months compared to 47 percent among the GM-CSF responders.
