Criteria

Inclusion Criteria:

healthy male or female subject, 18 to 50 years of age, inclusive, at least 45 kg and has a body mass index (BMI) of 18 to 33 kg/m2,
Female subjects of childbearing potential must not be pregnant and not lactating or prepared to practice highly effective birth control methods
The subject has normal 12-lead ECG results or, if abnormal, the abnormality is not clinically significant (as determined by the investigator).

Exclusion Criteria:

has evidence of cardiac conduction abnormalities
history of unexplained syncope, cardiac arrest, unexplained cardiac arrhythmia or torsade de pointes, structural heart disease, or family history of Long QT syndrome (suggested by sudden death of a close relative due to cardiac causes at a young age
potassium, calcium, or magnesium levels that are below the clinical laboratory's lower limit of normal
laboratory test results at Screening are >2 x the upper limit of normal (ULN) for alanine aminotransferase (ALT) or aspartate aminotransferase (AST), >1.5 x ULN for bilirubin, or >1.5 x ULN for creatinine
history or evidence of any clinically significant (as determined by the investigator) cardiovascular, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal, and/or other major disease or malignancy (excluding non-melanoma skin cancer)
febrile illness or symptomatic viral, bacterial (including upper respiratory infection), or fungal (non-cutaneous) infection within 1 week before clinic admission
supine mean systolic blood pressure <90 or >140 mmHg and a mean diastolic blood pressure <50 or >90 mmHg
positive for HIV or hepatitis C antibody or hepatitis B antigen (HBsAg)

Difference Between Active and Placebo for Time Matched Baseline Adjusted Mean QTcF

The primary endpoint is the difference between the active (HA44) and placebo for time matched baseline adjusted mean QTcF = [ΔQTcF (Ha44 0.74% Gel) - ΔQTcF (placebo)] = ΔΔQTcF. This was compared with the difference between Moxifloxacin and placebo for time matched baseline adjusted mean QTcF = [ΔQTcF (Moxifloxacin) - ΔQTcF (placebo)] = ΔΔQTcF
