             surgery)

          -  Subject has received hematopoietic stem cell transplant (HSCT) and falls under either
             of the following:

               -  Is within 2 months of transplant

               -  Has persistent and clinically significant graft-versus-host disease requiring

          -  Subject has clinically active central nervous system leukemia

          -  Subject has disseminated intravascular coagulation (DIC)

          -  Subject has had major surgery within 28 days prior to the first study drug
             administration

             administration

          -  Subject has congestive heart failure of NYHA class 3 or 4, or subject with a past
             history of congestive heart failure of NYHA class 3 or 4 and in whom echocardiogram or
             Multiple Gate Acquisition (MUGA) scan performed within 3 months prior to screening or
             at screening showed a left ventricular ejection fraction (LVEF) of < 45%.

          -  Subject requires treatment with concomitant drugs that are strong inhibitors or
             inducers of CYP3A4 or of P-gp with such exceptions of antibiotics, antifungals, and
             antivirals that are considered absolutely essential for prevention or treatment of
             infections and for which the physician judged that there are no interchangeable drugs.

          -  Subject requires treatment with concomitant drugs that target serotonin 5HT1R or
             5HT2BR receptors or sigma nonspecific receptors, with the exception of drugs that are
             considered absolutely essential for treatment of the subject.

          -  Subject has an active uncontrollable infection

          -  Subject is known to have human immunodeficiency virus (HIV) infection
