Retapamulin Ointment 1% Group
Subjects with clinically diagnosed with impetigo, folliculitis, or minor soft tissue infection suitable for treatment with a topical antibiotic were screened, and if qualified, they received topical retapamulin ointment 1% twice daily for 5 days.

PRIMARY outcome

Timeframe: 6 to 8 days after treatment

Population: Participants whose wound cultures were positive for MRSA

Clinical success is defined as no further signs or symptoms of infection present, including erythema, purulence, crusting, edema, warmth and pain.

Number of Participants Whose Wound Cultures Were Positive for MRSA and Who Were Determined to be a Clinical Success at the Follow-up Visit
5 participants

SECONDARY outcome

Timeframe: 6 to 8 days after treatment

Population: All participants who had a pathogen isolated from the treatment area at baseline upon microbiological testing

Clinical response was based on clinical evaluation by the investigator at the follow-up visit using a predefined scale with the following categories: (1) clinical success, (2) clinical improvement, (3) no change, (4) clinical failure, and (5) unable to determine. Patients who were designated as clinical success as defined in number 1 above were considered a true "clinical success" while all others were considered a "clinical failure." Patients were classified with an outcome of "unable to determine" if they missed their follow-up visit or refused clinical examination.

SECONDARY outcome

Timeframe: 6 to 8 days after treatment

Population: All participants who had a pathogen isolated from the treatment area at baseline upon microbiological testing

Microbiological response was determined by the investigator at the follow-up visit using the following microbiological outcomes: (1) microbological eradication, (2) presumed microbiological eradication, (3) presumed microbiological improvement, (4) microbiological persistence, (5) presumed microbiological persistence, (6) unable to determine, (7) new pathogen, and (8) colonization. Patients who were designated microbiological eradication, presumed microbiological eradication, presumed microbiological improvement, or colonization as defined in numbers 1, 2, 3, and 8 above were considered a "microbiological success" while all others were considered "microbiological failure."

SECONDARY outcome

Timeframe: 6 to 8 days after treatment

Population: All participants who had a pathogen isolated from the treatment area at baseline upon microbiological testing

Therapeutic response was determined from the clinical response and the microbiological response. Patients who qualified as both a "clinical success" and a "microbiological success" were deemed a "therapeutic success," and all others were deemed "therapeutic failures."

Timeframe: baseline

Population: All participants who had a pathogen isolated from the treatment area at baseline upon microbiological testing

Wound size area was determined by measuring the greatest length of the wound in two perpendicular dimensions with a standard metric ruler. The two measurements were multiplied together to provide an estimate of the overall wound size. Surrounding erythema was not included in the measurement.
