Criteria

Inclusion Criteria:

• Healthy adult male or female subjects, 18-55 years of age who provided written informed consent.

• A body mass index (BMI) between 18 - 30, inclusive.

• A normal blood pressure (< 140mmHg systolic and < 90mmHg diastolic)

• A normal 12-lead ECG (QTcF interval < 450msec for males and < 470msec for females).

• A serum potassium
• A calculated creatinine clearance > 80mL/min.

• Male subjects must agree to use a medically acceptable contraceptive (abstain from sexual intercourse, or use a condom with spermicide), have had a vasectomy at least 6 months prior to study participation or have a partner who is not of childbearing potential.

Exclusion Criteria:

• A history or presence of significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, or psychiatric disease.

• A history of sensitivity or allergy to the quinolone class of antibiotics and/or a beta 2 adrenergic receptor agonist.

• Clinically significant screening results (laboratory profiles, medical histories, ECGs, physical exam).

• Hemoglobin below the normal reference range for the testing laboratory.

• Abuse of alcohol or other substances.

• Current use of tobacco products.

• Subjects with a positive laboratory test result for hepatitis B, hepatitis C, HIV, controlled substances, cotinine or alcohol.

• Any prescription medication taken within 14 days (or 5 elimination half-lives, whichever is longer) of Study Day -2, or have taken any over-the-counter medications, including topical medications, vitamins, herbal or dietary supplements/remedies (e.g., Saint John's Wort or Milk Thistle), within 14 days of Study Day -2, or planned concomitant medication while in the study (except for acetaminophen up to 2g/day), with the exception of hormonal birth control medications or hormone replacement therapy for females.

• A history of additional risk factors for Torsade de Pointes (e.g., hypokalemia, history of drowning survival, family history of Long QT Syndrome, family history of Short QT Syndrome, or family history of unexplainable early sudden death).

• Subject is pregnant or lactating female, or female at risk of pregnancy (i.e., not using an adequate contraceptive method: surgical sterilization [e.g., bilateral tubal ligation], hormonal contraception [implantable, patch, oral], IUD, and double-barrier methods [any double combination of: male or female condom with spermicidal gel, diaphragm, sponge, cervical dap]_.

• Participation in a study of an investigational drug within 30 days prior to the baseline ECG.

• Any condition that, in the judgment of the Investigator, would place a subject at undue risk, or potentially compromise the results or interpretation of the study.
