Study Arms (2)

CBL-514 Group 1

EXPERIMENTAL

Eligible participants will be enrolled and randomized into one of 2 dose groups. Group 1 with 10 mg CBL-514 per injection.

Drug: 10 mg CBL-514 per injection

CBL-514 Group 2

EXPERIMENTAL

Eligible participants will be enrolled and randomized to one of 2 dose groups. Group 2 with 15 mg CBL-514 per injection.

Drug: 15 mg CBL-514 per injection

Interventions

10 mg CBL-514 per injection DRUG

The total injection volume per lipoma will be based on the lipoma size, as determined by ultrasound. Dosing sceme is presented as below: Lipoma diameter of ≥1.0cm and ≤2.0cm - 1 injection (2 mL each); total of 10 mg CBL-514. Lipoma diameter of \>2.0cm and ≤3.5cm - 2 injections (2 mL each); total of 20 mg CBL-514. Lipoma diameter of \>3.5cm and ≤5.0cm - 3 injections (2 mL each); total of 30 mg CBL-514. Lipoma diameter of \>5.0cm and ≤6.0cm - 5 injections (2 mL each); total of 50 mg CBL-514.

CBL-514 Group 1

15 mg CBL-514 per injection DRUG

The total injection volume per lipoma will be based on the lipoma size, as determined by ultrasound. Dosing sceme is presented as below: Lipoma diameter of ≥1.0cm and ≤2.0cm - 1 injection (3 mL each); total of 15 mg CBL-514. Lipoma diameter of \>2.0cm and ≤3.5cm - 2 injections (3 mL each); total of 30 mg CBL-514. Lipoma diameter of \>3.5cm and ≤5.0cm - 3 injections (3 mL each); total of 45 mg CBL-514. Lipoma diameter of \>5.0cm and ≤6.0cm - 5 injections (3 mL each); total of 75 mg CBL-514.

CBL-514 Group 2

Eligibility Criteria

• Age: 18 Years - 64 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Male or female, aged 18 years to 64 years old (at Screening), inclusive.
• Body mass index (BMI) \>18.5 kg/m2 at Screening and Day 1.
• Has confirmed Dercum's disease and/or fulfills the following clinical criteria of Dercum's disease in localized nodular form. The final diagnosis of disease is in the opinion of the PI.
• Chronic pain (\> 3 months) in the adipose tissue
• Pain in and around multiple lipomas.
• Has at least 4 painful and well defined lipomas with a diameter of ≥1.0 cm and ≤6.0 cm as determined by ultrasound. Excluding lipomas in proximity to vulnerable anatomic structures, including the salivary glands, lymph nodes, muscles, and along the anatomic landmarks of the marginal mandibular nerve.
• Generally considered healthy according to medical history, physical examination, electrocardiogram (ECG), and laboratory evaluation.
• Voluntarily signs the Informed Consent Form (ICF) and, in the opinion of the PI or designee, is physically and mentally capable of participating in the study, and willing to adhere to study procedures.

You may not qualify if:

• Women of childbearing potential (WOCBP) who are 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 are currently pregnant or lactating. Male participants who are not willing to commit to an acceptable contraceptive method. Female participants who are not WOCBP are not required to use contraception.
• Participants that are unable to tolerate subcutaneous injections.
• Participants that are diagnosed with another disorder with similar characteristics as Dercum's Disease.
• Participants that are diagnosed with coagulation disorders or is receiving anticoagulant/antiplatelet therapy or medications or dietary supplements, which inhibit coagulation or platelet aggregation.
• Participants who has fasting glucose concentration \>200 mg/dL, delayed wound healing, bleeding risk, or any diabetic risks which, in the opinion of PI or designee, is inappropriate to participate in the study.
• Participants with any clinically significant cardiac, hepatic, renal or neurologic/psychiatric disorders that in the opinion of the PI places the participant at significant risk.
• Participants with positive blood screen for Hepatitis B surface antigen (HBsAg), Hepatitis C virus, or Human immunodeficiency virus (HIV).
• Participants with clinical history of active primary or secondary immunodeficiency, autoimmune disease, or is undergoing chronic steroid or immunosuppressive therapy.
• Participants with active, suspected, 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 the skin and in situ squamous cell carcinoma of the skin would be eligible as per PI's discretion.
• Participants with abnormal skin, local skin conditions, or body modifications at the treatment area, which in the opinion of the PI, is inappropriate for participation in the study, including but not limited to prior wound, scar tissue, infection in the treated area, or tatoo in the treated area.
• Participants requiring continual use of the following therapeutic agents during the study: terfenadine, buspirone, fexofenadine, any medication that is known to strongly inhibit or induce CYP enzymes, sensitive CYP substrates or drugs with narrow therapeutic index, in the opinion of the Investigator, may affect the evaluation of the study product or place the participant at undue risk. If a participant requires the abovementioned therapeutic agents during the study for any reason, they should not be used for at least 2 days before dosing and until 1 day postdose.
• Participants that undergone aesthetic procedure (eg, liposuction, cryolipolysis, ultrasonic lipolysis, low level laser therapy \[LLLT\], lipolysis injection) to the region to be treated before Screening or during the study.
• Participants who are unable to receive local anesthesia.
• Participants with known allergies or sensitivities to the IP or its components.
• Participants that are in use of other investigational drug or device within 4 weeks prior to Screening.
