According to an Astellas spokesman, telavancin achieved its primaryendpoint of non-inferiority in both studies, and the compound comparedfavourably to standard therapy in clinical cure, microbiologicaleradication, and overall therapeutic response rates. Its safety profilewas compatible with treatment of patients with serious infections. Thefirm filed a new drug application in the USA for telavancin in Februarythis year.
