Inclusion Criteria:
All subjects must meet all of the following criteria to be included in the study:

or lactating, and must have a negative serum pregnancy test result before enrollment
into the study, and must be willing to use contraception as specified in section
12.8.3 or abstain from sexual activity for the duration of the study and for at least
3 weeks after discontinuation of study drug;
4. Male subjects and their partners of childbearing potential must use two methods of
contraception, one of which must be a barrier method, for the duration of the study
and for 30 days after completion;
5. Agree to abstain from alcohol consumption up to 3 days before dosing and throughout
duration of the study (including the Study Day 13 visit);
6. Agree to abstain from strenuous exercise from 3 days before dosing and throughout
duration of the study (including the Study Day 13 visit);
7. Able to effectively communicate with the investigator and other testing center
personnel;
8. Able to participate, and willing to give written informed consent and to comply with
the study restrictions.
Exclusion Criteria:
All subjects with any of the following conditions or characteristics must be excluded from
the study:
1. Currently participating in another study of an investigational drug (or a medical
device) or have participated in another clinical study of an investigational drug (or
a medical device) within 30 days of Study Day -1, 5 half-lives or twice the duration
of biological effect of the previous investigational drug (whichever is longer);
2. Known hypersensitivity to any component in the formulation of the study drug,
bardoxolone methyl;
3. Any medical or dental procedure, no matter how minor, that is planned or anticipated
to occur during the conduct of the study;
4. History of drug or alcohol abuse or dependence within the last year;
5. History of smoking or tobacco use within the 6 months prior to Study Day -1;
6. Donation or receipt of blood or blood components within the 4 weeks prior to Study Day
-1. The investigator should instruct subjects who participate in this study not to
donate blood or blood components for 4 weeks after the completion of the study;
7. History of unexplained syncope, cardiac arrest, unexplained cardiac arrhythmia or
Torsades de Pointes, structural heart disease, or family history of long QT syndrome
(suggested by sudden death due to cardiac causes at a young age of a close relative);
8. Evidence of any of the following cardiac conduction abnormalities based on the safety
ECG at Screening:
- Fridericia's correction for QT (QTcF) interval > 450 ms for males, > 470 ms for
females;
- PR interval < 110 ms or > 240 ms;
- Intraventricular conduction delay with QRS duration >120 ms;
- Resting heart rate < 40 bpm or > 90 bpm;
- Pathological Q-waves (defined as Q-wave > 40 ms or depth > 0.4-0.5 mV);
- Second- or third-degree atrioventricular block (AVB);
- Electrocardiographic evidence of complete left bundle branch block (LBBB), right
bundle branch block (RBBB), or incomplete left bundle branch block (LBBB);
- Ventricular pre-excitation;
- Atrial fibrillation, atrial flutter, or artificial cardiac pacemaker;
9. Screening ECG renders measurement of QT interval in lead II imprecise (for example:
flat T waves, arrhythmias);
10. Subjects who have a screening supine blood pressure (BP) outside 90-145 mm Hg systolic
or 45-95 mm Hg diastolic (measured following at least a 10-minute rest). Blood
pressure may be re-tested twice in the supine position at intervals of 5 minutes. The
pressure elevation is considered sustained if either the systolic or the diastolic
pressure exceeds the stated limits after three assessments and the subject may not be
randomized;
11. Use of any concomitant medications that are known to prolong QT/QTc interval within 30
days prior to Study Day -1;
12. Allergy to moxifloxacin or any fluoroquinolone antibiotic;
13. A positive test for drug(s) of abuse (alcohol, amphetamines, benzodiazepines,
barbiturates, cocaine, opiates, or cannabinoids) at the screening or the Day -2 visit;
14. Any concurrent clinical conditions that in the judgment of the investigator could
either potentially pose a health risk to the subject while involved in the study or
could potentially influence the study outcome;
15. Positive test results for human immunodeficiency virus type 1 or 2 antibody at
screening;
16. Any condition possibly affecting absorption, distribution, metabolism or excretion of
drugs that may confound the analyses conducted in this study (for example: previous
surgery on the gastrointestinal tract that includes removal of parts of stomach,
bowel, liver, gall bladder, pancreas, venocaval shunts, or transjugular intrahepatic
portosystemic shunts]);
17. Evidence or history of or concurrent clinically significant allergic (except for
untreated, asymptomatic, seasonal allergies at time of dose administration),
hematological, endocrine, immunological, renal, pulmonary, gastrointestinal,
cardiovascular, hepatic, psychiatric, or neurological disease that in the judgment of
the investigator could potentially either pose a health risk to the subject during the
study or influence the study outcome;
18. Evidence of hepatic or biliary dysfunction including elevation of total bilirubin,
direct bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT),
gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), or alkaline phosphatase
levels to greater than the upper limit of normal (ULN) at screening;
19. Abnormal hematological and biochemical parameters, including neutrophil count < 1500
cells/mm3, Hgb < 11 g/dL in females or < 12 g/dL in males, platelet count < 90,000
cells/mm3, creatinine = 1.5 X ULN, albumin = 3 g/dL, serum amylase or lipase = 1.5X
ULN at screening;
20. Positive test results for hepatitis B virus antibody, or hepatitis C virus antibody at
screening;
21. Use of or need for any prescription or non-prescription systemic drug(s) including
vitamins or herbal preparations other than drugs used for contraception, aspirin,
acetaminophen, or other non-steroidal anti-inflammatory agents, within 10 days before
Study Day -1 or during the study;
22. Use of aspirin, non-steroidal anti-inflammatory agents, or acetaminophen within 5 days
prior to Study Day -1;
23. Consumption of alcohol- or caffeine-containing compounds within 24 hours before Day -2
visit;
24. Consumption of citrus juice within the 7 days before Day -2 visit.
