Summary
1. Study Objective - To assess the effect of HSG4112 on body weight - To evaluate the safety and tolerability of HSG4112 2. Background Glaceum Inc. has evaluated the safety, tolerability, and pharmacokinetic/pharmacodynamic properties of HSG4112 in healthy subjects through its Phase 1 trials, and is planning to perform this Phase 2a trial to assess the safety and efficacy of HSG4112 in overweight and obese patients. 3. Number of Subjects This study is a Phase 2a clinical trial designed to evaluate the safety and efficacy of HSG4112 following multiple-dose administration. The subject sample size estimate for the primary efficacy endpoint was based on total body weight, and assumes repeated measurement of body weight occurs at Baseline and every 4 weeks thereafter during the 12-week treatment period. Based on similar weight loss studies with obesity drugs, the covariance matrix for body weight change over time is estimated as AR(1) (sigma = 3.07, rho = 0.9). Thus, with 20 subjects completing each treatment group, this study can detect a mean difference of 6 kg between HSG4112 and matching placebo treatments with 80% power, assuming a two-sided α-level of 0.05. Therefore, the target sample size for this study is 20 subjects/group. 4. Study Design and Protocol This study is a randomized, double-blind, placebo-controlled, parallel-groups trial. Subjects deemed eligible to participate in this study based on the inclusion/exclusion criteria will be assigned a subject number and randomized to one of the 4 treatment groups - 1 group receiving placebo - in a 1:1:1:1 ratio. Subjects will be randomized to double-blind treatments and will receive a once-daily oral dose of the investigational product for 12 weeks according to the study protocol. Body weight and obesity/metabolism-related parameters will be evaluated to assess the efficacy of HSG4112. Assessments including measurement of vital signs, 12-lead ECG, clinical laboratory tests, pregnancy test, physical examination, and adverse event monitoring will be performed to evaluate the safety and tolerability of HSG4112. Blood samples will be collected for pharmacokinetic assessment and samples from subjects who have signed the consent form for the exploratory genetic research will undergo analysis to detect PON2 gene polymorphism.

Criteria
Inclusion Criteria:

1. Able to comprehend and willing to sign an informed consent form approved by the IRB
before Screening.

2. 19 to 70 years, inclusive, at Screening.

3. BMI is 30 to 39.9 kg/m2, inclusive (obese), with or without comorbid conditions, or
BMI is 27 to 29.9 kg/m2, inclusive (overweight), with at least 1 documented treated or
untreated comorbid condition (e.g., hypertension, dyslipidemia, cardiovascular
disease, glucose intolerance, sleep apnea). All comorbid conditions must be considered
by the Investigator to be clinically stable.

☞ (BMI (kg/m2) = Weight (kg) / {Height (m)2})

4. Eligible females will be:

- females of childbearing potential who are not pregnant, evidenced by a negative
serum hCG pregnancy test at Screening

- non-lactating, or

- surgically sterile (defined as documented bilateral tubal ligation, bilateral
tubal occlusion, bilateral oophorectomy, hysterectomy) or postmenopausal (defined
as at least 12 months prior to Screening without menses with no alternative
explanation for the absence of menses).

5. Eligible males should have no plans to have children up to 90 days following the last
day of treatment.

6. A history of at least 1 unsuccessful weight loss attempt, per Investigator judgment.

Exclusion Criteria:

1. Clinically significant new illness, per Investigator judgment, in the 1 month before
Screening and during the screening period.

2. Significant history or clinical manifestation of allergic reaction or hypersensitivity
to the investigational product or any related drug compound.

3. Compliance with placebo self-administration is ≤80% during the 2-week single-blind
placebo run-in period.

4. Weight loss >3% during the 2-week single-blind placebo run-in period.

5. Diabetes mellitus (type 1, type 2, or other). A remote history of gestational diabetes
that has resolved is not exclusionary.

6. Previous or planned (for the duration of the study) bariatric surgery or device (i.e.,
gastric bypass, gastric banding, sleeve gastrectomy, gastric balloon, biliopancreatic
diversion)

7. Anticipated surgery during the study that may interfere with study completion or
compliance with the protocol.

8. Uncontrolled hypertension at Screening, defined as systolic blood pressure ≥160 mmHg
or diastolic blood pressure ≥100 mmHg. Subjects with uncontrolled hypertension at
Screening may be re-screened >3 months following initiation or adjustment of
antihypertensive therapy, if enrollment has not been closed.

9. Any of the following within 3 months of Screening: myocardial infarction, unstable
angina, cerebrovascular accident, transient ischemic attack, and cardiac arrhythmia
requiring medical or surgical treatment.

10. Evidence of any other unstable or untreated clinically significant hepatic, renal,
neurological, immunological, respiratory, endocrine, hematological, cardiovascular,
psychiatric, or neoplastic disease, or disease that, based on Investigator's judgment,
will make the subject inappropriate for the study.

11. Males with the following:

- history of, or known cause of hypogonadism (e.g., treatment for prostate cancer)

- history of infertility

- Klinefelter's syndrome or Kallmann's syndrome
