Efficacy - Change in Lipomas DimensionsPrimary· 0-84 days
Evaluation of the efficacy of RZL-012 following injection into lipomas/nodules of Dercum's Disease (DD) subjects. Efficacy will be determined by ultrasound assessment of the lipoma/nodule dimensions after treatment vs baseline. Lipomas Dimensions will be measured for active vs. placebo at days 28,56,84

Time frame: 6 months.
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
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.
