RZL-012 for Dercum's Disease Lipomas

This is a multi-center, randomized, double blind, placebo controlled clinical trial in DD subjects having lipomas. Subjects will be randomized, in a 1:1 ratio, into two groups injected with either RZL-012 or vehicle.

Once the study ends and codes are opened, 84 days after dosing, placebo-treated subjects will be offered the option of receiving treatment with RZL-012 and followed up for an additional 84 days.

At least 4 lipomas/nodules, preferably 6, and no more than 8, will be injected per subject, two of which will be medium (4-5.9 cm), large (6-7.9 cm) or extra-large (8-10 cm) in diameter. Dosing will be according to lipoma size, where the total injected dose will not exceed 240 mg per patient (48 injections at 5mg/injection).

Inclusion criteria

• At least 4 painful lipomas of appropriate size to be injected on a background of Dercum's Disease.
• Generally considered healthy according to medical history, physical examination, electrocardiogram (ECG) and laboratory evaluation with an emphasis on metabolic parameters (fasting glucose concentration < 200 mg/dL).
• Subjects must be able to adhere to the visit schedule and protocol requirements and be capable of completing the study.
• Males or females in the age of fertility are willing to refrain from sexual activity or agree to use a double-barrier contraceptive device (e.g., condom and spermicide) for 4 weeks after treatment with RZL 012.
• Subjects must sign an informed consent indicating they are aware of the investigational nature of the study.

Exclusion criteria

• Unable to tolerate subcutaneous injections.
• Pregnant women.

• Subjects with dysfunctional gallbladder activity, e.g. underwent cholecystectomy or cholecystitis.
• As a result of medical review and physical examination, the PI (or medically qualified nominee) considers the subject unfit for the study.
• Known sensitivity to components of the injection formulation.
• Prior wound, tattoo or infection in the treated area.
• Prior invasive treatment such as surgery or injectable drug at the RZL-012 injected area.
