ribonucleic acid is negative.
9. Does not meet study site COVID-19 admission/study participation restrictions.
10. Has a fever (>38oC).*
11. Had major surgery or donated or lost 1 unit of blood (approximately 500 mL) within 4

12. Is unable to refrain from the use of prohibited prescription or non-prescription drugs
including vitamins, herbal and dietary supplements (including St John's Wort) within 7
days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever
is longer) prior to the first dose of study medication through completion of study
participation.
As detailed in Section 10.1, allowable concomitant medications may include HMG-CoA
reductase inhibitors (statins), =2 permissible anti-hypertensive agents,
postmenopausal hormone replacement therapy, and/or proton pump inhibitors (PPIs).
13. Has been on any GLP-1 receptor agonist, any dipeptidyl peptidase IV (DPP-4) inhibitor,
or any approved or investigational medications known to cause weight loss in the prior
3 months.
14. Has a history of type 1 diabetes mellitus (T1DM) or a history of diabetic ketoacidosis
or subject assessed by the investigator as possibly having T1DM.

wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) or use any of
soft drugs(such as marijuana) within 3 months prior to Screening, or hard drugs (such
as cocaine) within 6 months prior to Screening.
22. Is unwilling or unable to refrain from consuming alcohol from 7 days prior to the
first dose of study medication through the completion of study participation.
23. Has a substance abuse disorder.
24. Had a previous major psychotic disorder.
25. Has a corrected QT interval to Fridericia's formula (QTcF) >450 milliseconds (msec)
for males and >470 msec for females at screening or admission.
26. Has a mean value for triplicate semi-recumbent systolic blood pressure >160
millimeters of mercury (mmHg) and/or diastolic blood pressure (BP) >95 mmHg measured
after at least 10 minutes at rest at the Screening Visit. Note: If a subject's BP is
exclusionary on the first triplicate assessment at the Screening visit, they may have
1 repeat triplicate BP assessment at that visit, after another rest of at least 10
minutes, to qualify for the study.
If a subject's BP is exclusionary at screening but the investigator feels that BP is
likely to be below the exclusionary thresholds at admission (Day -2), this criterion
can be re-assessed at admission. Adjustment of doses of anti-hypertensives already
being taken at screening is permissible, but initiation of new agents is not
permissible. For subjects whose BP is exclusionary at Screening and at the first
triplicate assessment on Day -2, triplicate assessments can be repeated up to twice on
Day -2, as needed.
27. Has alanine aminotransferase or aspartate aminotransferase (ALT or AST) of >1.0X upper
limit of normal (ULN) or total bilirubin >1.2X ULN (isolated bilirubin >1.2X ULN is
acceptable if bilirubin is fractionated, and direct bilirubin is within the laboratory
normal range) at Screening or admission. (Note: Subjects who do not meet this
criterion at Screening or at admission may not be rescreened/retested).
28. Has serum amylase or lipase >1.2X the ULN at the Screening Visit.
29. Has a recent history (within past 3 years) or current diagnosis of any of the
following GI (gastro-intestinal) related diseases: intestinal obstruction, GI
perforation, GI motility disorders, adhesions, Clostridium difficile colitis or have

hematological, hepatic, immunological, renal, respiratory, neurologic disorder,
neoplastic, or genitourinary abnormalities or diseases.
33. Has a history of any illness that, in the opinion of the study investigator, might
confound the results of the study or poses an additional risk to the subject by their
participation in the study.
note - *Subject may be included if they are able to return to the site within 7 days of
initial screening and the exclusion criterion is no longer met.
