Primary

MeasureTime frameDescription
Clinical Response 7 to 14 Days After Completion of Study Drug Therapy in Per Protocol (PP) Population7 - 14 days after completion of study drug therapyClinical cure was defined as: Reduction of the tenderness score (modified McCormack) by \> 70% and apyrexia (rectal/tympanic/oral temperature value \< 38.0°C or axillary temperature value \< 37.5°C) and white blood cell count \< 10,500/mm\^3.

Secondary

MeasureTime frameDescription
Clinical Response on Treatment for Per Protocol Population4 - 7 days after start of therapyAt the During Therapy (Day 4 to 7) assessment, the clinical response was graded as clinical Improvement (severity score reduced by \>30% with improvement in temperature, clinical failure (reduction in severity score of \< or equal 30% and/or no improvement in temperature) or indeterminate (clinical assessment not possible to determine).
Clinical Response on Treatment for Intent To Treat Population4 - 7 days after start of therapyClinical response during treatment was analyzed exploratively in the same way as the primary efficacy variable. At the During Therapy (Day 4 to 7) assessment, the clinical response was graded as clinical Improvement, clinical failure or indeterminate accordingly. Clinical improvement was considered success, all other outcomes as non-success.
Bacteriological Response at Test Of Cure (TOC) Visit Microbiologically Valid7 - 14 days at TOC visitThe bacteriological responses was based on the results of appropriate cultures taken before and, if necessary, during treatment, at the TOC visit and within the follow-up period. Bacteriological response at the TOC visit would also be based on repeated PCR tests for N. gonorrhoeae and C. trachomatis.
Bacteriological Response at Test Of Cure (TOC) Visit in Intent To Treat Population With Causative Organism7 - 14 days at TOC visitBacteriological response at the TOC was analyzed exploratively in the same way as the primary efficacy variable based on the subgroup of microbiologically valid subjects. At the TOC visit, eradication was considered a bacteriological success, and persistence, presumed persistence and superinfection were considered bacteriological failures.
Clinical Response 7 to 14 Days After Completion of Study Drug Therapy on Intent To Treat (ITT) Population7 - 14 days after completion of study drug therapyFor any subject in the ITT population also valid for the PP analysis, same clinical response as in the PP analysis was applied to the ITT analysis. For those subjects in the ITT population invalid for the PP analysis, any clinical response different from clinical cure was set to non-success.
Clinical Response at Follow-up Visit on Intent To Treat Population28 - 42 days after completion of study drug therapyAll successfully treated subjects and subjects evaluated asindeterminate at TOC, who were not administered an additional antibiotic therapy would have their clinical response rate assessed at the follow-up visit. Patients with missing or indeterminate outcome were treated as non-successes.
Bacteriological Response at Follow-up Visit Microbiologically Valid28 - 42 days after completion of study drug therapySubjects with at least one causative organism identified in the pre-therapy culture or a positive pre-therapy PCR result and an appropriate post-therapy bacteriological evaluation available were analyzed. Bacteriological responses at follow-up visit was analyzed exploratively in the same way as the primary efficacy variable.

Participant flow

Recruitment details

A total of 463 females with uncomplicated PID were enrolled on the basis of a complete evaluation (interview, medical history and physical examination and laboratory tests). 460 subjects were randomized, 412 completed study treatment (whole medication), and 384 subjects were valid for the primary efficacy analysis.

Pre-assignment details

The efficacy results in ITT are consistent with those in PP, supporting that this is a non-inferiority study and the primary efficacy population was PP not ITT. 76 subjects were excluded from primary efficacy analysis mainly due to essential data missing or invalid, violation of inclusion/exclusion criteria and insufficient duration of therapy.

Outcome results

Primary

Clinical Response 7 to 14 Days After Completion of Study Drug Therapy in Per Protocol (PP) Population

Clinical cure was defined as: Reduction of the tenderness score (modified McCormack) by \> 70% and apyrexia (rectal/tympanic/oral temperature value \< 38.0°C or axillary temperature value \< 37.5°C) and white blood cell count \< 10,500/mm\^3.

Time frame: 7 - 14 days after completion of study drug therapy

Population: The number of subjects in the PP population was slightly higher than the planned number of subjects (184 subjects per treatment group). The most common reasons for exclusion from the population valid for efficacy in both the Moxifloxacin and Comparator were essential data missing/invalid, followed by violation of inclusion/exclusion criteria.
