Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Estimate the relative bioavailability of co-administered azithromycin microsphere (2000 mg) and the chloroquine (620 mg CQ base) test formulation compared to co-administered immediate release individual tablets of azithromycin (2000 mg) and chloroquine (600 mg CQ base) in healthy adult subjects.

Detailed Description

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy male and/or female subjects between the ages of 18 and 55 years, inclusive (Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12 lead ECG and clinical laboratory tests).
* Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight \>50 kg (110 lbs).
* An informed consent document signed and dated by the subject or a legally acceptable representative.
* Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion Criteria

* Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
* History of febrile illness within 5 days prior to first dose.
* Treatment with azithromycin within the past 30 days or with chloroquine within the past 45 days.
* Known immediate family history of prolonged QT Syndrome, serious ventricular arrhythmia, or sudden cardiac death. "Immediate" is considered "first degree".
* Known allergy to macrolide antibiotics (eg, erythromycin, clarithromycin, azithromycin) or chloroquine (or other 4 aminoquinolines) or severe allergic reaction to any drug in the past (eg, difficulty breathing, anaphylaxis).
* History of intolerance to azithromycin or chloroquine.
