Trial Outcomes & Findings for Comparison of Delafloxacin Versus Ceftriaxone for the Treatment of Uncomplicated Gonorrhea (NCT NCT02015637)

NCT ID: NCT02015637

Last Updated: 2018-06-20

Results Overview

Cure for the primary outcome measure was defined as the eradication of N. gonorrhoeae at TOC as determined by a negative culture obtained from the urogenital site, which was positive at study entry, and with no additional antibiotics with activity against N. gonorrhoeae being administered from study entry through TOC.

PRIMARY outcome

Timeframe: Day 7 (± 3 days)

Population: The primary efficacy analysis was done on the UMITT population, which included all subjects in the ITT analysis set who had a positive culture for N gonorrhoeae obtained at a urogenital site at the Entry Visit, and who did not receive antibiotic therapy for a C trachomatis infection that was potentially effective against N gonorrhoeae prior to TOC.

Cure for the primary outcome measure was defined as the eradication of N. gonorrhoeae at TOC as determined by a negative culture obtained from the urogenital site, which was positive at study entry, and with no additional antibiotics with activity against N. gonorrhoeae being administered from study entry through TOC.

Collection of all AEs occurred from the time the subject received study drug (Day 1) through the TOC visit (Day 7 +/- 3), or up to 10 days. Only Serious Adverse Events (SAEs) were collected after the TOC visit through the follow-up phone contact (Day 30 +/- 3 days), or up to 33 days.
AEs were reported in the Safety Population which was defined as all subjects that received study drug. Two patients that were in the ITT population (all subjects randomly assigned to a treatment group) for delafloxacin did not receive study drug.
