Primary Outcome Measures:
  • The bacterial eradication rate, as measured by conversion from positive Neisseria gonorrhoeae baseline urethral or cervical culture to negative [ Time Frame: 3 to 9 days after study drug dosing ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety and tolerability of a single oral dose of CEM-101 in adult patients with uncomplicated urogenital gonorrhea [ Time Frame: One day after study drug dosing, and 3 to 9 days after study drug dosing ] [ Designated as safety issue: Yes ]
    Adverse event reporting, clinical laboratory evaluations

  • The bacterial eradication of rectal or pharyngeal gonococcal infection (if positive culture at baseline) [ Time Frame: 3 to 9 days after study drug dosing ] [ Designated as safety issue: No ]
  • Eradication or persistence of N. gonorrhoeae nucleic acid (as measured by positive NAAT assay) from urethral and cervical specimens [ Time Frame: 3 to 9 days after study drug dosing ] [ Designated as safety issue: No ]
  • Eradication or persistence of Chlamydia trachomatis nucleic acid (as measured by positive NAAT assay) from urethral and cervical specimens [ Time Frame: 3 to 9 days after study drug dosing ] [ Designated as safety issue: No ]
  • In vitro minimum inhibitory concentrations (MICs) of gonococcal strains isolated [ Time Frame: Baseline and (if applicable) 3 to 9 days after study drug dosing ] [ Designated as safety issue: No ]

Ages Eligible for Study:   19 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Evidence of a urogenital gonococcal infection (prior culture, NAAT test, Gram stain, sexual contact)
  2. Willing to abstain from anal, oral, or vaginal sexual intercourse or use condoms until study completion.
  3. Females of childbearing potential (including females less than 2 years post-menopausal) must have a negative pregnancy test at enrollment.

Exclusion Criteria:

  1. Confirmed, or suspected, complicated or systemic gonococcal infections such as pelvic inflammatory disease, arthritis, or endocarditis.
  2. Known HIV, chronic hepatitis B, or hepatitis C infection.
  3. Known concomitant infection which would require additional systemic antibiotics.
  4. Use of systemic or intravaginal antibiotics within 30 days prior to study drug administration.
  5. Current use of corticosteroid drugs or other immunosuppressive therapy.
  6. Cytotoxic chemotherapy or radiation therapy within the previous 3 months.
  7. Known significant renal, hepatic, or hematologic impairment.
  8. History of intolerance or hypersensitivity to macrolide antibiotics.
  9. Any concomitant condition that, in the opinion of the Investigator, would preclude an evaluation of a response or make it unlikely that the contemplated course of therapy and follow-up could be completed (e.g., life expectancy <30 days).
