             inclusive.

          -  Agreement to avoid strenuous exercise starting 4 days before the start of dosing
             through the period of confinement in the clinical unit and for at least 96 hours
             before the follow-up visits.

        Exclusion Criteria:

          -  History of allergy to drugs in the iminosugar class.

          -  Treatment with any investigational products or therapies within 30 days (or 5
             half-lives, whichever is greater) before the first day of dosing.

          -  Current or past history of disease/dysfunction of the pulmonary, cardiovascular,
             endocrine, hematologic, neurological, immune, gastrointestinal genitourinary, or other
             body system.

          -  Abnormalities on physical examination suggestive of conditions that may pose an
             increased risk to the subject; abnormal electrocardiogram results (excluding benign
             conditions); and Grade 1 or higher abnormalities in vital signs at screening and Grade
             2 or higher abnormalities in vital signs at check-in based on a modified version of
             the FDA Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in
             Preventive Vaccine Clinical Trials.

          -  Clinical laboratory tests outside the normal range at screening and Grade 2 or higher
             at check-in to the clinical unit.

          -  Creatinine clearance < 90 mL/min (based on Cockcroft-Gault equation).

          -  Proteinuria greater than or equal to 1+.

          -  Any known or expected risk of bleeding.

          -  Scheduled surgical procedure during study participation.

          -  History of alcohol and/or drug abuse within 1 year prior to dosing and/or a positive
