Criteria
Inclusion Criteria:

- 1. Adult male or females, 28 to 65 years of age (inclusive) at the time of informed
consent with BMI between 28.0 and 45.0 kg/m2 (inclusive).

1. Female subjects of childbearing potential must be non-lactating, not pregnant as
confirmed by a negative urine pregnancy test at Screening and agree to continue
using an effective method of contraception for at least 4 weeks or barrier method
for 2 weeks prior to first study drug administration until 30 days after the last
dose of study drug (Section 8.3.2).

2. Female subjects of childbearing potential must not donate ova during the study
and for at least 30 days after the last dose of study drug.

3. Female subjects of non-childbearing potential must be surgically sterile (e.g.,
hysterectomy, bilateral tubal ligation, oophorectomy) or postmenopausal (no
menses for >1 year with follicle stimulating hormone (FSH) >40 U/L at Screening).

4. Male subjects who have not had a vasectomy and/or subjects who have had a
vasectomy but have not had 2 post surgery negative tests for sperm must agree to
use an acceptable method of contraception from time of first dose of study drug
until 30 days after the last dose of the study drug, and to not donate sperm
during the study and for at least 30 days after the last dose of study drug.

2. Inclusion as per investigator assessment of general medical status and as
documented by medical history, physical examination, vital sign assessments,
12-lead ECG, clinical laboratory assessments, and general observations.

1. Subjects must be on stable doses of medications for underlying obesity-related
conditions for at least 2 months prior to screening.

2. Subjects with diabetes may be treated with metformin, DPP-4 inhibitors, or
sulfonylureas, but must be on stable doses for at least 2 months prior to
screening.

3. At Screening, certain laboratory values may be outside the reference range if
commensurate with the underlying obesity or associated metabolic dysfunction in
the eligible subject (for example, dyslipidemia and hyperglycemia), unless these
abnormalities suggest an underlying condition which may impact subject safety in
the trial or interfere with the evaluation of HU6 or affect interpretation of the
study results.

4. Abnormalities or deviations outside the normal ranges for other assessments that
are considered clinically significant by the Investigator (clinical laboratory
tests, ECG, vital signs, physical examination) may be repeated once at the
discretion of the Investigator(s). Results that continue to be outside the normal
ranges must be judged by the investigator to be not clinically significant and
acceptable for study participation.

5. Subjects with elevation of unconjugated bilirubin due to presumptive Gilbert's
syndrome are permissible.

6. Subject must be euthyroid as assessed by a thyroid profile utilizing thyroid
stimulating hormone (TSH) and free thyroxine (T4) testing at screening. Subjects
