Treatment of Women With Lipedema Involving Substantial Fat Knee of Women and Men With Nodular Dercum's Disease

This is an open label, 2 cohort, clinical trial in women with lipedema with substantial fat above the knee and men with Dercum's disease.

• The 1st cohort will be comprised of subjects with Dercum's disease.
• The 2nd cohort will be comprised of subjects with lipedema with substantial fat above the knee

Within each cohort dosing of the subjects will progress consecutively from one individual to the other with a minimum 7 days between subjects to asses safety. The study design will allow the physicians to monitor safety for at least 7 days prior to dosing the next subject. Cohort 2 will be conducted in a dose escalation manner and the decision to proceed to the next dose level will be made after reviewing all safety data collected by Day 14 within 2+/-1 day of the last dosed subject. The trial will proceed within a cohort provided that no more than one subject experience intolerable side effects in a cohort, and based on the decision made by the Principal Investigator (PI) and the medical monitor.

Inclusion criteria

• Post-menopausal (at least 2 years) women no more than 65 years old, with lipedema involving substantial fat above the knee or nodular Dercum's disease in such women and in men 20 - 65 years with nodular Dercum's disease.
• For Dercum's disease subjects - at least 2 nodules to be injected of at least 2cm diameter each, as determined by ultrasound
• For lipedema subjects - Significant subcutaneous fat above the knee as determined by circumference of 50cm
• Generally considered healthy according to medical history, physical examination, ECG and laboratory evaluation with a special emphasis on metabolic parameters (fasting glucose concentration < 100 mg, normal blood pressure).
• Subjects must be able to adhere to the visit schedule and protocol requirements and be available to complete the study.
• Subjects must sign an informed consent indicating that they are aware of the investigational nature of the study.

Exclusion criteria

• Unable to tolerate subcutaneous injection.

• Subjects with a clinical history of primary or secondary immunodeficiency, autoimmune disease or subjects taking immunosuppressive drugs such as corticosteroids are ineligible.
• As a result of medical review, 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.
