 -  Acute or chronic clinically significant pulmonary, cardiovascular, hepatic, metabolic,
 neurologic, psychiatric or renal functional abnormality, as determined by medical
 history, physical examination or clinical laboratory screening tests, which in the
 opinion of the investigator, might interfere with the study objectives. Subjects with
 physical examination findings or clinical laboratory screening results which would be
 graded 2 or higher on the AE severity grading scale (see Attachments) will be excluded
