Pelvic Inflammatory Disease

Brief summary

Azithromycin had a potent in vitro activities and broad spectrum from typical and atypical bacteria to anaerobes. Azithromycin intravenous formulation demonstrated high efficacy and eradication rate in the western clinical trials. Development of azithromycin intravenous formulation would bring the clinical benefit to patients with pelvic inflammatory disease (PID) in Japan.

Interventions

DRUGAzithromycin

The patients will receive 500 mg intravenous azithromycin QD for 1 to 2 days. The period of administration of intravenous dosing is judged by investigators according to patient status. Following intravenous administration, the patients will be received the 250 mg oral azithromycin (tablet formulation) QD to complete a total of 7 days therapy.

MeasureTime frameDescription
Response Rate (Clinical Response, Data Review Committee Assessment) in Participants Who Enrolled After Protocol Amendment (the Inclusion Criterion Regarding Fever of 37℃ or Higher Was Option)End of Treatment, Day 15 and Day 29Response 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. The inclusion criterion regarding fever was amended from the required criteria to the additional criteria in consultation with the regulatory authority. The subset of participants who were enrolled after the protocol amendment was the primary analysis sets for efficacy.

Outcome results

Primary

Response Rate (Clinical Response, Data Review Committee Assessment) in Participants Who Enrolled After Protocol Amendment (the Inclusion Criterion Regarding Fever of 37℃ or Higher Was Option)

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. The inclusion criterion regarding fever was amended from the required criteria to the additional criteria in consultation with the regulatory authority. The subset of participants who were enrolled after the protocol amendment was the primary analysis sets for efficacy.

Time frame: End of Treatment, Day 15 and Day 29

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