Trial Outcomes & Findings for Comparison of Telavancin and Vancomycin for Complicated Skin and Skin Structure Infections With a Focus on Methicillin-resistant Staphylococcus Aureus (NCT NCT00091819)

NCT ID: NCT00091819

Last Updated: 2019-01-16

Results Overview

The Clinical Response for each patient was determined by the investigator by assessing a patient's clinical signs and symptoms at the specified evaluation compared with the Baseline evaluation. Cure: resolution of signs and symptoms associated with the skin infection present at study admission such that no further antibiotic therapy was necessary; Not Cured: inadequate response to study therapy; Indeterminate: unable to determine outcome.

PRIMARY outcome

Timeframe: 7-14 days following end of antibiotic treatment

Population: Data for the all-treated (AT) population are presented. the AT and clinically evaluable (CE) populations were considered co-primary.

The Clinical Response for each patient was determined by the investigator by assessing a patient's clinical signs and symptoms at the specified evaluation compared with the Baseline evaluation. Cure: resolution of signs and symptoms associated with the skin infection present at study admission such that no further antibiotic therapy was necessary; Not Cured: inadequate response to study therapy; Indeterminate: unable to determine outcome.
