Brief summary

This is a multi-center Phase 2 randomized, open-label study in approximately 180 adult male and female subjects, between the ages of 18 and 55, who are in good health and meet all eligibility criteria. The study is designed to assess the safety and efficacy of an antimicrobial investigational product, AZD0914 manufactured by AstraZeneca, administered to adults to treat uncomplicated urogenital gonorrhea compared to treatment with ceftriaxone. Subjects will be randomly assigned 70:70:40 to receive a single, oral dose of 2000 mg of AZD0914, 3000 mg of AZD0914, or intramuscular dose of 500 mg of ceftriaxone. The drug name is also known as ETX0914.

Detailed description

Uncomplicated gonorrhea is currently the second most common bacterial sexually transmitted infection (STI) worldwide and, accordingly, is a serious public health problem. This is a multi-center Phase 2 randomized, open-label study in approximately 180 adult male and female subjects, between the ages of 18 and 55, with uncomplicated cervical or urethral gonorrhea. The study is designed to assess the safety and efficacy of an antimicrobial investigational product, AZD0914 manufactured by AstraZeneca, administered to adults to treat uncomplicated urogenital gonorrhea compared to treatment with intramuscular ceftriaxone. Subjects will be randomly assigned 70:70:40 to receive a single, oral dose of 2000 mg of AZD0914, 3000 mg of AZD0914, or intramuscular dose of 500 mg of ceftriaxone. The study duration is 11 months and subject participation of 30 days. Subjects with 1) untreated urethral or cervical gonorrhea identified via laboratory testing at a prior visit, or 2) untreated subjects acknowledging anal, oral, or vaginal sexual contact in the past 14 days with someone diagnosed with gonorrhea, or 3) signs and symptoms of urethral or cervical gonorrhea will be offered enrollment in the study and consented. The primary objective assess the efficacy by microbiological cure rate of 2000 mg or 3000 mg AZD0914 compared to 500 mg ceftriaxone for the treatment of uncomplicated urogenital gonorrhea. The second primary objective assess the safety and tolerability of a single oral dose of 200 mg or 3000 mg AZD0914 compared to 500 mg ceftriaxone in adult subjects with uncomplicated urogenital gonorrhea. The drug name is also known as ETX0914.

Interventions

AZD0914 is an antimicrobial amorphous nonsterile powder. Group 1 receive 2000 mg; Group 2 receive 3000 mg. The drug name is also known as ETX0914.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Microbiological Cure at Urethral or Cervical Sites in Each Study ArmDay 6Microbiological 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.
Number of Participants Reporting Adverse Events (AEs) and Serious Adverse Events (SAEs) Considered Product-related.Day 1 through Day 31Adverse 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.

MeasureTime frameDescription
Number of Participants With Clinical Cure in Each Study ArmDay 6A 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.
Number of Participants With no Detectable N. Gonorrhoeae Nucleic Acid in Urethral/Cervical Specimens in Each Study Arm at Baseline.Day 1 (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.
Number of Participants With no Detectable N. Gonorrhoeae Nucleic Acid in Urethral/Cervical Specimens in Each Study Arm at Day 6.Day 6Gonorrhea and Chlamydia nucleic acid amplification tests (GC/CT NAAT) were performed at Day 6 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.
Number of Participants With no Detectable N. Gonorrhoeae Nucleic Acid in Rectal Specimens in Each Study ArmBaseline and Day 6Gonorrhea and Chlamydia nucleic acid amplification tests (GC/CT NAAT) were performed at baseline and Day 6 with specimens collected at the rectal 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.
Number of Participants With no Detectable N. Gonorrhoeae Nucleic Acid in Pharyngeal Specimens in Each Study ArmBaseline and Day 6Gonorrhea and Chlamydia nucleic acid amplification tests (GC/CT NAAT) were performed at baseline and Day 6 with specimens collected at the pharyngeal 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.
Number of Participants With Microbiological Cure at Rectal Sites in Each Study ArmDay 6Microbiological cure was assessed at the TOC visit. Microbiological cure was derived from the Neisseria gonorrhoeae culture result and assessed by anatomical site. All participants were swabbed at the rectal site. Remel RapID NH tests were performed on pure cultures obtained from swab specimens. A subject was defined as a microbiological cure if N. gonorrhoeae was not detectable by culture at TOC.
Median in Vitro MIC Against AZD0914/ETX0914 and Ceftriaxone of Gonococcal Isolates From Culture of Isolates From the Urethral/Cervical Sites at Day 6Day 6For all positive cultures of specimens collected from the urethra or cervix, isolates were collected and tested for antimicrobial susceptibility profiles and the 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.

For all positive cultures of specimens collected from the rectum, isolates were collected and tested for antimicrobial susceptibility profiles and the 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.

Time frame: Day 6

Population: The analysis population includes all participants who had isolates collected and results reported at the timepoint, of which there were none for this anatomical site and timepoint.

Number of Participants With Clinical Cure in Each Study Arm

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.

Time frame: Day 6

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.
