History of bariatric surgery 3. Current liver, renal, pulmonary, cardiac, oncologic, metabolic, gastrointestinal or hematologic disease which the Investigator believes is clinically significant, including: 1. Liver disease or liver injury as indicated by abnormal liver function tests (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase , serum bilirubin) \>3 × upper limit of normal (ULN), or history of hepatic cirrhosis 2. History or presence of impaired renal function as indicated by an estimated glomerular filtration rate \<60 ml/hr or urine albumin-to-creatinine ratio \>35 mg/mmol 3.

Participation in another investigational trial within 4 weeks prior to the screening visit. The 4 week window will be derived from the date of the last trial medication and/or blood collection in a previous trial and/or adverse event (AE) related to trial drug to the screening visit of the current trial. 10.

Translational Research Institute (TRI) staff member or immediate relative of TRI staff member, directly involved with this study 16. History of any illness or condition that, in the opinion of the study investigator, might confound the results of the study or poses an additional risk to the subject by study participation
