Conditions

Dercum's Disease Lipomas

Brief summary

Thirty-eight (38) subjects will be included in the study. Subjects will be randomized in a ration of 1:1 to be treated with RZL-012 or placebo. Subjects will be injected with a different doses of RZL-012 according to their lipomas sizes. The total of 38 subjects will be enrolled in 3 clinical sites.

Detailed description

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 uncontrolled cardiac, hepatic, renal or neurologic/psychiatric disorders, that in the opinion of the investigator places the subject at significant risk. * Positive blood screen for Hepatitis B surface antigen (HbSAg), Hepatitis C virus (HCV), or Human immunodeficiency virus (HIV). * Subjects with a clinical history of active primary or secondary immunodeficiency, autoimmune disease or subjects taking immunosuppressive drugs such as corticosteroids * 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. * Subjects treated chronically at least 3 months prior to study entry with systemic steroids or immunosuppressive drugs. * Subjects treated chronically at least one week prior to study entry with Non-Steroidal Anti-Inflammatory Drugs (NSAIDs). * Current participation or participation within 3 months prior to the start of this study in a drug or other investigational research study.

RZL-012
A single-treatment injection, multiple subcutaneous injections of RZL-012 administered into 4-8 lipomas in each subject, preferably 6. Dosing will be done according to lipomas size, as will be determined by Ultrasound. Each injection contains 0.1mL RZL-012 (5mg). Lipomas in the size of: 2-3.9 cm will be dozed with 0.4mL RZL-012 (20mg). 4-5.9 cm will be dozed with 0.8mL RZL-012 (80mg). 6-7.9 cm will be dozed with 1 mL RZL-012 (100mg). 8-10 cm will be dozed with 1.2 mL RZL-012 (120mg).
