PRIMARY outcome

Timeframe: End of treatment, Test of cure (7 days after End of treatment), Long term follow up (7 days after Test of cure)

Population: Clinical per protocol set consisted of all participants who received at least one dose, have no significant violation of protocol, and underwent prescribed evaluations during the observation period. No imputation was used for missing data. "n" in the Measure Values means total participants EXCLUDING ones assessed as indeterminate.

Response rate was calculated from the following formula, "the number of participants assessed as effective" over "total participants excluding ones assessed as indeterminate" multiplied by 100.

SECONDARY outcome

Timeframe: Day 4

Population: Clinical per protocol set consisted of all participants who received at least one dose, have no significant violation of protocol, and underwent prescribed evaluations during the observation period. No imputation was used for missing data.

The number of participants who showed tendency toward clinical improvement based on the assessment of temperature, white blood cell count, C-reactive protein, clinical symptoms on Day 4 and was determined to continue the treatment.

SECONDARY outcome

Timeframe: Day 4, End of treatment, Test of cure (7 days after End of treatment), Long term follow up (7 days after Test of cure)

Population: Bacteriologic per protocol set consisted of all participants in the clinical per protocol set in whom bacterial pathogens were identified at baseline. No imputation was used for missing data. "n" in the Measure Values was the total participants EXCLUDING ones assessed as indeterminate.

Eradication Rate was calculated from the following formula, "the number of participants assessed as eradication, presumed eradication or microbial substitution" over "total participants excluding ones assessed as indeterminate" multiplied by 100. Microbial substitution means the appearance of new pathogens other than the original pathogens in a specimen from the same location with signs and symptoms of infection after the original pathogens were eradicated by treatment.

Timeframe: Day 4, End of treatment, Test of cure (7 days after End of treatment), Long term follow up (7 days after Test of cure)

Population: Bacteriologic per protocol set consisted of all participants in the clinical per protocol set in whom bacterial pathogens were identified at baseline. No imputation was used for missing data. "n" in the Measure Values was the total participants EXCLUDING ones assessed as indeterminate.

Eradication Rate was calculated from the following formula, "the number of participants assessed as eradication , presumed eradication or microbial substitution" over "total participants excluding ones assessed as indeterminate" multiplied by 100. Microbial substitution means the appearance of new pathogens other than the original pathogens in a specimen from the same location with signs and symptoms of infection after the original pathogens were eradicated by treatment.
