Trial Outcomes & Findings for Randomized, Open-label Phase 2 Study of Oral AZD0914 in the Treatment of Gonorrhea (NCT NCT02257918)

NCT ID: NCT02257918

Last Updated: 2017-03-22

Results Overview

Microbiological cure was assessed at the Test of Cure visit (TOC). Microbiological Cure was derived from the Neisseria gonorrhoeae culture result and assessed by anatomical site. Male participants were swabbed at the urethral site and female participants at the cervical site. Remel RapID NH tests were performed on pure cultures obtained from swab specimens. A participant was defined as a microbiological cure if N. gonorrhoeae was not detectable by culture at TOC.

Timeframe: Day 1 through Day 31

Population: All participants who received the study treatment were included in the analysis population. One participant enrolled in the Ceftriaxone arm was pregnant at enrollment and therefore, not treated.

Adverse events are defined as any untoward medical occurrence regardless of its causal relationship to the study treatment. Serious adverse events included any untoward medical occurrence that resulted in death; was life threatening; was a persistent/significant disability/incapacity; required inpatient hospitalization or prolongation thereof was a congenital anomaly/birth defect; or may have jeopardized the subject or required intervention to prevent one of the outcomes. Relationship to study product was determined by the investigator and defined as a reasonable possibility that the study product caused the adverse event. Reasonable possibility means that there is evidence to suggest a causal relationship between the study product and the adverse event.

Population: The analysis population was restricted to participants who had a positive culture result for N. gonorrhoeae at any anatomical site and reported signs or symptoms of gonorrhea at baseline.

A clinical cure was defined as the resolution of all signs and symptoms of gonorrhea (e.g. cervical/vaginal/urethral discharge, dysuria, dyspareunia, vulvovaginal irritation, sore throat) that were present at enrollment with the exception of vaginal discharge due to yeast vaginitis or bacterial vaginosis. A clinical failure was defined by the presence of any sign or symptom of gonorrhea that was also present at enrollment with the exception of vaginal discharge due to yeast vaginitis or bacterial vaginosis. The investigator also submitted his/her determination of whether the participant met or did not meet the criteria for clinical cure (or whether it is unknown if the participant met the criteria). In the event the investigator's assessment of clinical cure did not coincide with the definitions of clinical cure/failure, the investigator's assessment was the final adjudicator.

Population: The analysis population was restricted to participants who had a positive cervical/urethral culture result for N. gonorrhoeae at baseline.

Gonorrhea and Chlamydia nucleic acid amplification tests (GC/CT NAAT) were performed at baseline with specimens collected at the cervical/urethral site. Detectable nucleic acid was derived from GC/CT NAAT testing. If N. gonorrhoeae nucleic acid was detected, the result of the test was classified as positive. If no nucleic acid was detected, the result of the test was classified as negative. If a clear result could not be determined for any reason, the result of the test was classified as indeterminate.

Population: The analysis population includes all participants who had isolates collected and results reported at the timepoint.

For all positive cultures of specimens collected from the urethra or cervix, isolates were collected and tested for antimicrobial susceptibility profiles and the minimum inhibitory concentration (MIC) was determined. MIC was defined as the lowest concentration of an antimicrobial that inhibited the visible growth of a microorganism after overnight incubation. The MIC breakpoint was a chosen concentration of an antibiotic which defines whether a bacterial isolate is susceptible or resistant to the antibiotic. If the MIC was less than or equal to the susceptibility breakpoint, the bacteria was considered susceptible to the antibiotic. If the MIC was greater than this value, the bacteria was considered intermediate or resistant to the antibiotic.
