Study Endpoints

Primary Endpoints

Number of Participants Achieving Clinical Response at Follow-up Who Had Methicillin-resistant Staphlococcus Aureus (MRSA) as a Baseline Pathogen
7-9 days post-therapy; Day 12-14 for retapamulin and Day 17-19 for linezolid

Follow-up is defined as 7-9 days post-therapy: Day 12-14 for retapamulin; Day 17-19 for linezolid. Clinical success at follow-up was defined as the resolution of clinically meaningful signs and symptoms of infection recorded at baseline, including a pus/exudate skin infection rating scale (SIRS) score of "0." The SIRS is used by the investigator to evaluate infected lesions. Scores on the SIRS range from 0 (absent) to 6 (severe).

Secondary Endpoints

Number of Participants Achieving Microbiological Response (MR) at Follow-up (FU) Who Had MRSA as a Baseline Pathogen (BP)
7-9 days post-therapy; Day 12-14 for retapamulin and Day 17-19 for linezolid
Number of Participants With Clinical Response at Follow-up
7-9 days post-therapy; Day 12-14 for retapamulin and Day 17-19 for linezolid
Number of Participants Who Achieved Microbiological Response (MR) at Follow-up (FU) Who Had a Baseline Pathogen (BP)
7-9 days post-therapy; Day 12-14 for retapamulin and Day 17-19 for linezolid
