Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Can healthy volunteers participate?
Yes
Key exclusion criteria
1. Past or present clinically relevant systemic disease as judged by the Investigator including, but not limited to, clinically relevant medical abnormalities such as psychiatric, neurologic, pulmonary, respiratory, cardiac, gastrointestinal, genitourinary, renal, hepatic, metabolic, endocrinologic, hematological, or autoimmune disorders making implementation of the protocol or interpretation of the study results difficult, or that would put the subject at risk by participating in the study in the opinion of the Investigator.
2. History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the Investigator (or designee).
3. Knowledge of any kind of cardiovascular disorder/condition/procedure known to increase the possibility of QT prolongation or a history of additional risk factors for torsade de pointes (eg, heart failure, hypokalemia, hypomagnesemia, congenital long QT syndrome, or family history of long QT syndrome, or Brugada syndrome), or cardiac conduction disorders.
4. Resting supine systolic blood pressure greater than 140 mm Hg; resting supine diastolic blood pressure greater than 90 mm Hg at Screening or Day -1. Blood pressure measurements may be repeated once at the discretion of the Investigator.
5. Resting supine HR less than 45 beats per minute or greater than 100 beats per minute at Screening or Day -1 (may be repeated once at the discretion of the Investigator). Minor deviations are acceptable if considered to be of no clinical significance by the Investigator.
6. Abnormal 12-lead ECG at Screening or Day -1 (a single repeat is allowed), including:

1. QTcF > 450 msec
2. QRS > 110 msec
3. PR > 200 msec
4. Second or third-degree atrioventricular block
7. Any rhythm other than sinus rhythm, which is interpreted by the Investigator to be clinically significant at Screening or Day -1.
8. Dosing in another clinical trial within the last 30 days (or 5 half-lives, whichever is longer) prior to Day -1.
9. Family history of unexplainable sudden death at < 50 years of age.
10. History of unexplained loss of consciousness, unexplained syncope, unexplained irregular heartbeats or palpitations, clinically significant head injury, or near drowning with hospital admission.
11. Known allergic reactions to moxifloxacin (for Part 2 only) or any study medication or history of tendonitis or tendon rupture as a result of moxifloxacin or any other quinolone type drug use (for Part 2 only).
