Any other disease or medical condition such as history or presence of cancer, cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunological, or neurological disease or disorder, that, in the opinion of the investigator, makes the subject unsuitable to participate in the trial.
-
Any abnormal laboratory or ECG findings that are clinically significant and would impact the safety of the subjects or the interpretation of the study results, as determined by the investigator.
