Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
CBL-514 will be administered via injection into the subcutaneous adipose layer on thigh. The intervention will be administered in a single dose escalation scheme with 4 sequential groups. The eligibility of the subjects in each sequential group are the same.
The design of dose escalation is 320, 480, 640 and 800 mg of CBL-514-active pharmaceutical ingredient which will be administered with 40, 60, 80, 100 injections respectively. The amount of CBL-514 per injection is 1.6 mL in all four groups. One dose of CBL-514 will be divided into two and evenly administered on both thighs. The dosing between groups will be separated by at least 7 days. Subject diary would be provided after dosing for subject to record their conditions.

Outcomes
Primary outcome [1] 324677 0
Safety and tolerability following single dose of CBL-514 as assessed by recording of treatment emergent adverse events (TEAEs), laboratory assessments, vital signs, ECGs, physical examinations, and injection site assessment.

Treatment-emergent adverse events will be summarized by system organ class, preferred term, severity, and suspected relationship to study drug.
The major adverse events may include localised pain, bruising, numbness, redness, swelling, edema, induration, itching, altered sensations, and skin tightness which would be around the injection sites.
Clinical laboratory test includes biochemistry, hematology, urinalysis, pregnancy status, and virology assessments. Physical examinations, vital signs, standard electrocardiogram and any other untoward medical events during the study period will also be recorded for assessment.

Key exclusion criteria
A subject who meets any of the following exclusion criteria must be excluded from the study:
1. Female subject of childbearing potential who is not willing to commit to an acceptable contraceptive regimen with her partner from the time of Screening and throughout study participation until 90 days after the last IP dose, or who is currently pregnant or lactating. Male subject who is not willing to commit to an acceptable contraceptive method.
Females who have been surgically sterilized (hysterectomy or bilateral oophorectomy) or who are post-menopausal (e.g., defined as at least 50 years with greater than or equal to 12 months of amenorrhea with a FSH >40 IU/L) are considered to be of non-childbearing potential.

4. Subject has a clinically significant cardiovascular disease and abnormal findings in electrocardiogram (ECG).
5. Subject with active or prior history of malignancies within 5 years before Screening or being worked-up for a possible malignancy. Except adequately treated basal cell carcinoma of skin and in situ squamous cell carcinoma of skin would be eligible as per Investigator’s discretion.
6. Subject with a history of human immunodeficiency virus (HIV)-1, infection or subjects with active HIV infection at Screening with positive HIV antigen/antibody (Ag/Ab) combo test.
7. Subjects with any hepatic medical condition that would interfere with assessment of safety or efficacy or compromise the subject's ability to undergo study procedures or provide informed consent.
8. Subject has abnormal skin or local skin conditions at the treatment area, which in the opinion of Investigator, is inappropriate to participate in the study, including but not limited to any of the following:
a. Skin manifestations of a systemic disease,
b. Any abnormality of the skin or soft tissues of the area to be treated,
c. Grade III cellulite (Nürnberger and Muller scale, Nürnberger F, 1978) at the area to be treated,
d. Skin or superficial tissue that does not lie flat on its own when the subject is in the supine position,
e. Sensory loss or dysesthesia in the area to be treated,
f. Evidence of any cause of enlargement in the area to be treated other than localized subcutaneous fat,
g. Tattoos on the area to be treated.
9. Subject who has undergone the following procedures:
a. Previous surgery in the anticipated treatment area,
b. Metal implants of any type in the area to be treated,
c. Esthetic procedure i.e. liposuction to the region to be treated within 12 months before Screening or during the study,
d. Esthetic procedure e.g. cryolipolysis, ultrasonic lipolysis, low level laser therapy (LLLT), lipolysis injection to the region to be treated within 6 months before Screening or during the study.
10. Subject is on prescription or OTC weight reduction medication or weight reduction programs within 3 months before Screening or during the study.
11. Subject is undergoing chronic steroid or immunosuppressive therapy.
