  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.

• 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.
