Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
CBL-514 will be administered via injection into the abdominal subcutaneous adipose layer. Eligible subjects will be randomized to 1 of 3 treatment groups: 180, 240, and 300 mg of CBL-514-active pharmaceutical ingredient. Subjects will receive 4 treatments of CBL-514 which will be given once every 2 weeks, over a period of 6 weeks. A total of 60 injections of CBL-514 will be evenly administered by 1.58 cm apart at the treatment area and the amount of each injection is 0.6, 0.8, and 1.0 ml based on the design of dose groups.

If a subject needs to use the above mentioned therapeutic agents during the study for any reason, these therapeutic agents should not be used at least for 48 hours prior to dosing until 24 hours post-dose or the collection of the last PK sample, whichever is later.

13. Unable to receive topical anesthesia (e.g., history of hypersensitivity to lidocaine).

14. Subjects with known allergies or sensitivities to the study drug and/or excipients.
