Subcutaneous Abdominal Fat
CBL-0204 Enrolling

Subcutaneous Abdominal Fat Research Study (25 Weeks)

Treatment: Injection Age: 18 Years

Recruiting adults aged 18 to 64 for a clinical trial investigating reducing subcutaneous abdominal fat. Eligible participants must have a stable body weight of 50 kg or greater (less than 3 kg weight change in the past 3 months), with a body mass between 18.5 and 30 kg/m2. Participants must also have maintained a stable lifestyle for at least 3 months (e.g., exercise, eating patterns, and smoking habit) and not have poorly-controlled diabetes within the past 6 months (requiring a change in glucose control medications other than day-to-day insulin requirement variations). A participant should not have folding fat or skin while standing, and not have tattoos on the area that is to be treated.

Participants will receive either an investigational injection treatment (study drug) or placebo. Study treatment and study-related assessments will be provided at no cost. Reimbursement for study-related expenses may be provided. Study participation will last about 25 weeks and involve about 9 visits to the study centre.

Caliway Biopharmaceuticals Co., Ltd.

Study Description

  • Brief Summary:

    This is a randomized, placebo-controlled, Phase 2b study to evaluate the efficacy, safety, and tolerability of CBL-514 injection for reducing subcutaneous fat.

  • Condition or Disease:

    Subcutaneous Fat

  • Intervention/Treatment:

    Drug: CBL-514 Injection
    Other: 0.9% Sodium Chloride
  • Phase:

    Phase 2

  • Ages Eligible for Study:

    18 Years and 64 Years (Adult)

  • Sexes Eligible for Study:


Inclusion Criteria:

Male or female, aged 18 years to 64 years old (at Screening), inclusive.
Body mass index (BMI) greater than 18.5 and less than 32 kg/m2 and body weight greater than or equal to 50 kg at Screening and Day 1.
Participant has abdominal fat graded by the Investigator as Grade 2 (mild), Grade 3 (moderate) or Grade 4 (severe) using the Abdominal Fat Rating Scale at Screening.
Participant has stable body weight (identified as less than or equal to 3 kg weight change per participant report) for at least 3 months before Screening and during the study.
Participant who has maintained a stable lifestyle (e.g., exercise, eating patterns, and smoking habit) per participant report for at least 3 months before Screening and during the study.
Voluntarily signs the Informed Consent Form (ICF) and, in the opinion of the Investigator or delegate, is physically and mentally capable of participating in the study, and willing to adhere to study procedures.

Exclusion Criteria:

Female participant of childbearing potential who is not willing to commit to an acceptable contraceptive regimen 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 participant who is not willing to commit to using of a condom and refraining from sperm donation from the time of the first dose of IP, throughout study participation until 90 days after the last IP dose.

Note: Participants who are not of childbearing potential are not required to use contraception. Females not of childbearing potential are defined as those who have been surgically sterilized (hysterectomy or bilateral oophorectomy) or who are post-menopausal (defined as at least 50 years of age with greater than or equal to 12 months of amenorrhea with a follicle stimulating hormone (FSH) greater than 30 IU/L).

Participant diagnosed with coagulation disorders or who is receiving anticoagulant/antiplatelet therapy or medications or dietary supplements that impede coagulation or platelet aggregation.
Participant has hemoglobin A1c (HbA1c) greater than or equal to 9%, delayed wound healing, or poorly controlled diabetes defined as requiring a change in glucose control medications (other than day to day variations in insulin requirements) within the 6 months prior to Screening or for whom a change in glucose control medications is anticipated during the study, or any diabetic risks that, in the opinion of Investigator, make the individual an inappropriate candidate for the study.
Participant with active or prior history of malignancies within 5 years before Screening or currently being evaluated for a possible malignancy, with the exception of adequately treated basal cell carcinoma of skin and in situ squamous cell carcinoma of skin at Investigator’s discretion.
Participant with a history of human immunodeficiency virus (HIV)-1 infection or participant with active HIV infection at Screening with positive HIV antigen/antibody (Ag/Ab) combo test.
Participant with a history of trypanophobia, the extreme fear of medical procedures involving injections or needles, or who experiences vasovagal syncope and faints at the sight of blood or a needle.
Participant with folding fat or skin on abdomen in standing position.
Participant with abdominal visceral fat that causes supra-umbilicus fat to be more bulging than infra-umbilicus fat.
Participant with ventral abdominal or umbilical hernia or previous repair of same

Participant has abnormal skin or local skin conditions at the treatment area, which, in the opinion of Investigator, would increase risk to the participant or inhibit safety or efficacy evaluation, including but not limited to any of the following:

Skin manifestations of a systemic disease,
Any abnormality of the skin or soft tissues of the area to be treated, such as scars, striae, dyspigmentation, etc.,
Asymmetrical fat on abdomen,
Lipomatosis syndromes (familial lipomatosis, nevus lipomatosis, Dercum’s disease, etc.),
Skin laxity on abdomen,
Sensory loss or dysesthesia in the area to be treated,
Tattoo(s) on the area to be treated.

Participant who has undergone the following procedures:

Previous surgery that caused scar tissues on the anticipated treatment area before Screening or during the study, with the exception of laparoscopic surgery and surgery that resulted in minimal scar tissue determined at Investigator’s discretion,
Liposuction or abdominoplasty to the region to be treated before Screening or during the study,
Aesthetic procedure for body contouring or fat reduction, e.g., cryolipolysis, ultrasonic lipolysis, low level laser therapy, EMSculpt, lipolysis injection to the region to be treated within 12 months before Screening or during the study.
Using medication that is delivered via subcutaneous injection at the treatment area within 4 weeks before Screening or during the study.
Participant is on prescription or OTC weight reduction medication, weight reduction programs, or use of any GLP-1 agonists (e.g., semaglutide, terzepatide, liraglutide, etc.) (oral or injectable) within 6 months before Screening or during the study.
Participant is undergoing chronic steroid or immunosuppressive therapy, with the exception of oral steroid inhalation indicated for asthma management or topical steroid application for skin conditions that are not directly applied to or indirectly affect the treatment area.

Requiring continual use of any medication that is known to strongly inhibit or induce CYP1A2 enzymes, sensitive CYP1A2 substrates or drugs with narrow therapeutic index during the study that, in the opinion of the Investigator, may affect the evaluation of the study product or place the participant at undue risk.

Note: If a participant needs to use the above mentioned therapeutic agents during the study for any reason, these therapeutic agents should not be used at least for 2 days prior to dosing and until 1 day post-dose.

Unable to receive local anesthesia (e.g., history of hypersensitivity to lidocaine).
Participant with known allergies or sensitivities to the IP or its components.
Participant with liver cirrhosis, with inadequate liver function at Screening defined as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, total bilirubin (TBIL), or gamma-glutamyl transferase (GGT) greater than 3.0 × upper limit of normal (ULN), or with any hepatic medical condition that would interfere with assessment of safety or efficacy.

Participant with any renal impairment, defined as:

serum creatinine greater than 1.5 × ULN and blood urea nitrogen (BUN) greater than 1.5 × ULN, or
estimated glomerular filtration rate (eGFR) less than 90 mL/min/1.73 m2, or who is currently on dialysis.

Note: Participant with an eGFR greater than or equal to 60 and less than 90 mL/min/1.73 m2 at Screening should be evaluated by the Investigator for pre-existing disease or associated dysfunction. If mild decrease in eGFR is deemed not clinically significant or not related to dysfunction by the Investigator, the participant will not be excluded unless the Investigator deems it necessary.

Participant with contraindications to MRI imaging.
