Trial overview
Official title: A Randomized, Double-Blind, Double Dummy, Comparative, Multicenter Study to Assess the Safety and Efficacy of Topical Retapamulin Ointment, 1%, versus Oral Linezolid in the Treatment of Secondarily-Infected Traumatic Lesions and Impetigo Due to Methicillin-Resistant Staphylococcus aureus
Trial description: The purpose of this study is to provide further evidence of the clinical andbacteriological efficacy of retapamulin in the treatment of subjects with SITL or impetigodue to MRSA. Subjects aged 2 months and older will be treated with either topicalretapamulin for 5 days or oral linezolid for 10 days. The primary endpoint is the clinicalresponse at follow-up (7-9 days after the end of therapy) in subjects who have a MRSAinfection at baseline. The primary population is the per-protocol MRSA population. It isanticipated that approximately 500 subjects may be enrolled in order to obtainapproximately 105 subjects who have a baseline MRSA infection.
Primary purpose:
Treatment
Trial design:
Parallel Assignment
Masking:
Double (Participant, Investigator)
Allocation:
Randomized
Primary outcomes:
Number of participants achieving clinical response at follow-up who had methicillin-resistant Staphlococcus aureus (MRSA) as a baseline pathogen
Timeframe: 7-9 days post-therapy; Day 12-14 for retapamulin and Day 17-19 for linezolid
Secondary outcomes:
Number of participants achieving microbiological response (MR) at follow-up (FU) who had MRSA as a baseline pathogen (BP)
Timeframe: 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
Timeframe: 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)
Timeframe: 7-9 days post-therapy; Day 12-14 for retapamulin and Day 17-19 for linezolid
Number of participants with the indicated clinical outcome at the end of therapy who had MRSA as a baseline pathogen
Timeframe: 2-4 days post-therapy; Day 7-9 for retapamulin and Day 12-14 for linezolid

Timeframe: 2-4 days post-therapy; Day 7-9 for retapamulin and Day 12-14 for linezolid
Number of baseline pathogens with the indicated microbiological outcome at the end of therapy
Timeframe: 2-4 days post-therapy; Day 7-9 for retapamulin and Day 12-14 for linezolid
Number of participants with therapeutic response at follow-up
Timeframe: 7-9 days post-therapy; Day 12-14 for retapamulin and Day 17-19 for linezolid
