Primary Outcome Measures:
  • Microbiological outcome of urogenital gonorrhea [ Time Frame: Day 7 (± 3 days) ]
    All subjects will return for the Test-of-Cure Visit. However, culture and NAAT swabs will not be collected from anatomical sites with negative cultures and NAAT results, respectively, for N. gonorrhoeae from the Entry Visit. If results are not known, a swab will be collected at each anatomical site tested at the Entry Visit.

Secondary Outcome Measures:
  • Microbiological response at all anatomical sites [ Time Frame: Day 7 (± 3 days) ]
  • Resolution of signs and symptoms [ Time Frame: Day 7 (± 3 days) ]

Enrollment: 460
Study Start Date: January 2014

Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)

Active Comparator: ceftriaxone
Ceftriaxone 250 mg intramuscular injection administered once
Drug: Ceftriaxone
single dose


Ages Eligible for Study:   15 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subject is a male or female 15 years of age or older.
  • Subject must have had 1 or more of the following occur:

    1. gonorrhea with the NAAT or culture within the previous 14 days
    2. unprotected genital contact within 14 days with a person confirmed to be infected with gonorrhea,
    3. gram-negative present in urogenital gram strain or male subject must present with purulent urethritis or a female subject with must present with mucopurulent cervical discharge
  • Subject agrees to avoid unprotected sexual contact in order to minimize the risk of gonorrhea reinfection
  • Subject must be in good health (ie, based on medical history), as determined by the investigator.
  • In the opinion of the investigator, the subject must be able and willing to comply with protocol requirements. The subject must agree to provide reliable, verifiable contact information and agree to return for the Test-of-Cure Visit.
  • If a subject's age is 15 years to less than the legal age of consent,a written, voluntarily signed assent must be obtained from the subject and a written, voluntarily signed informed consent must be signed by the subject's parent or legal guardian before the initiation of any study related procedures, unless the IRB/IEC determines that parent/legal guardian consent is not required.

Exclusion Criteria:

  • Confirmed, or suspected, complicated or systemic gonococcal infection, such as pelvic inflammatory disease, arthritis, or endocarditis.
  • Subject has taken one of the following products within 6 hours of the Entry Visit that may interfere with the absorption of a quinolone antibiotic: magnesium/aluminum antacids; sucralfate; Videx® (didanosine) chewable/buffered tablets; other highly buffered drugs; or other products containing calcium, iron, or zinc.
  • Use of systemic or intravaginal antibiotics that are potentially effective against gonorrhea 4 weeks prior to study drug administration.
  • Subjects with a current or prior history of seizures, and subjects being treated with drugs that are known to have a sizable potential of or reduce the threshold for inducing seizures (eg, bupropion, theophylline, and tricyclic and tetracyclic antidepressants).
  • Current use of systemic corticosteroid or immunosuppressive drugs.
  • Known significant immunosuppression (eg, CD4 cell count <200/mm3 or absolute neutrophil count <500/mL).
  • Cytotoxic chemotherapy or radiation therapy during the previous 3 months.
  • Subject is co-infected with an additional sexually transmitted disease (STD) for which treatment cannot be safely deferred until after the Test-of-Cure Visit unless the treatment is not potentially effective against gonorrhea.
  • Subject has used an investigational drug or product within 30 days before study drug dosing.
  • Medical history of Type 1 hypersensitivity to antibiotics of the quinolone or cephalosporin classes.
  • Hysterectomized subjects without a cervix are ineligible.
