CBL-0205 Enrolling

Subcutaneous Abdominal Fat Research Study (21 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 27 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 a fear of injections or needles (or faints at the sight of blood or needles), not have folding fat or skin while standing, and not have tattoos on the front and/or lateral side of abdomen.

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.

    Drug: CBL-514 injection
    Drug: CBL-A1 Injection
    Drug: CBL-A2 Injection
    Drug: 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) >18.5 and < 27 kg/m2 and body weight ≥ 50 kg at Screening and Day 1. Participant has abdominal fat graded by the Investigator as Grade 3(moderate) or Grade 4(severe) using the Clinician-Reported Abdominal Fat Rating Scale via in-person examination at Screening. Participant has stable body weight (identified as ≤ 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 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 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. 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) ≥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 active HIV infection at Screening with positive HIV antigen/antibody combo test. Participant with a history of trypanophobia, the extreme fear of medical procedures involving injections or needles, or who experiences vasovagal syncope or faints at the sight of blood or a needle. Participant with folding fat or skin on abdomen in standing position. Participant with severe or very severe abdominal visceral fat using the visceral fat scale. 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 and 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 front and/or lateral side of abdomen. 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 tissues 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 with contraindications to MRI imaging Participant is on prescription or OTC weight reduction medication, weight reduction program, or any GLP-1 agonist (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 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. Unable to receive local anesthesia. 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(ALP), total bilirubin (TBIL), or gamma-glutamyl transferase (GGT) >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 abnormal serum creatinine and blood urea nitrogen (BUN) >1.5× ULN or estimated glomerular filtration rate (eGFR) <90mL/min/1.73 m2, or who is currently on dialysis. Use of any investigational drug or device within 3 months prior to Screening.
