Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomized treatment assigments are provided to the site pharmacist following enrollment of each patient using a centralized enrollment resource. The site pharmacist prepares the study treatments and they are labeled for administration in a blinded fashion per a site specific blinding plan.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
SAS programming was utilized to generate a blocked, stratified random allocation sequence
Masking / blinding
Blinded (masking used)

Summary
Brief summary
A large multinational, double-blind, randomized Phase III clinical study designed to compare the efficacy and safety of telavancin (10mg/kg IV once daily) versus vancomycin (1gm IV q12 hr) in adult patients with complicated skin and skin structure infections (cSSSI) caused by Gram-positive bacteria.

The primary objective of the study was to compare the efficacy and safety of telavancin to vancomycin in the treatment of adults with complicated Gram positive skin and skin structure infections with an emphasis on patients with infections due to methicillin resistant Staphylococcus aureus (MRSA). A key secondary objective of this study was to pool the data from this study with data from a second study of identical design (Study 0018) and to assess the superiority of telavancin to vancomycin in patients with MRSA infections.

Patients were assessed for clinical response by assessing a patient’s signs and symptoms at the specified evaluation compared to their Baseline evaluation. A cure consisted of resolution of signs and symptoms associated with the skin infection present at study admission such that no further antibiotic therapy was necessary. Not cured meant there was an inadequate response to study therapy and Indeterminate meant the outcome was not able to be determined.
