* Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) = 2.5 x ULN. For the purposes of this study the ULN of ALT and AST is 45 U/L.
* Total bilirubin = ULN; or if > ULN then direct bilirubin = 1.5 x ULN
* Female participants of childbearing age must have a negative pregnancy test at the time of enrollment.
* Participants of childbearing or child fathering potential must be willing to use medically acceptable form of birth control during treatment and for 16 weeks after stopping treatment.
* Participants and/or guardian have the ability to understand and the willingness to sign a written informed consent document according to institutional guidelines.

Strata A and B

* Participant who is receiving any other investigational agents.
* Participants with other clinically significant medical disorders (i.e. serious infections or significant cardiac, pulmonary, hepatic, psychiatric, or other organ dysfunction) that could compromise their ability to tolerate protocol therapy or would interfere with the study procedures or results.
* Participant with a history of clinically significant, uncontrolled heart disease and/or repolarization abnormalities as documented by a standard 12-lead ECG.
* Shortening fraction of <27% by ECHO or ejection fraction of <50% by gated radionuclide study.
* Prior history of QTc prolongation or QTc interval of > 480 msec.
* Female participants who are breastfeeding a child.
