Background:

Partial lipodystrophy is a deficiency of body fat in parts of the body (usually the arms and legs). People with partial lipodystrophy often get high blood triglyceride (fat) level, insulin resistance, diabetes and other problems. Researchers think the new drug ISIS 304801 can help treat health problems caused by partial lipodystrophy.

Objective:

To see if ISIS 304801 will improve blood fat (triglyceride levels), diabetes, and liver disease, and reduce some risks for heart disease caused by partial lipodystrophy.

Eligibility:

Adults at least 18 years old with partial lipodystrophy.

Design:

Participants will be screened during a 1-week stay at NIH. They will have:

Blood and urine tests

Physical exam.

Assignment to get either the study drug or placebo.

Instructions for how to inject the drug.

Body measurements.

Heart tests.

Participants will give themselves injections of the drug or placebo once a week at home. Some may test blood sugar by finger pricks. They will have monthly phone calls and nurse visits to take blood tests.

After 4 months, participants may continue the study for 1 year. All participants will get the study drug.

Participants will have study visits at NIH every 4 months. These may include:

Insulin sensitivity measurement: Insulin and sugar will be infused through 2 intravenous (IV) lines in the arms. Blood will be drawn.

Sugar and fat metabolism measured by IV infusions and blood tests.

Special x-ray scan to measure body fat.

Liquid meal then blood collected by IV catheter in the arm.

Magnetic resonance imaging scans.

Neck ultrasound.

Questionnaires.

Liver biopsy (optional)

Injection of heparin (a blood thinner) before a blood test.

After finishing the drug, participants will have 1 nurse visit and 1 visit to NIH.

Eligibility

INCLUSION CRITERIA:

-Age greater than or equal to 18 years at enrollment (the time of informed consent, week -1)

-Fasting TG levels greater than or equal to 500 mg/dL (greater than or equal to 5.7 mmol/L) at enrollment. If the fasting TG value is <500 mg/dL (<5.7 mmol/L) but greater than or equal to 350 mg/dL (greater than or equal to 4.0 mmol/L) up to two additional tests may be performed in order to qualify, and a single level greater than or equal to 500 mg/dL will permit enrollment.

OR

-Fasting TG levels greater than or equal to 200 mg/DL (2.6mmol/L) with a hemoglobin A1C over 7%.

-Willing to maintain their customary physical activity level and to follow a diet moderate in carbohydrates and fats with a focus on complex carbohydrates and replacing saturated for unsaturated fats

-Clinical diagnosis of lipodystrophy based on deficiency of subcutaneous body fat in a partial fashion assessed by physical examination, and low skinfold thickness in anterior thigh by caliper measurement: men (less than or equal to 10mm) and women (less than or equal to 22mm), plus one of the following:

---Genetic diagnosis of familial PL (e.g., mutations in LMNA, PPARG, AKT2, or PLIN1 genes) OR

--Family history of familial PL or abnormal and similar fat distribution PLUS 1 minor criterion (below), OR

--2 minor criteria (below) in the absence of genetic diagnosis of family history

--MINOR Criteria

--Diabetes mellitus with requirement for high doses of insulin, eg, requiring greater than or equal to 200 U/day,greater than or equal to 2 U/kg/day, or currently taking U-500 insulin

--Presence of acanthosis nigricans on physical examination

--History of polycystic ovary syndrome (PCOS) or PCOS-like symptoms (hirsutism, oligomenorrhea, and/or polycystic ovaries)

--History of pancreatitis associated with hypertriglyceridemia

--Evidence of non-alcoholic fatty liver disease: Hepatomegaly and/or elevated transaminases in the absence of a known cause of liver disease or Radiographic evidence of hepatic steatosis (e.g., on ultrasound or CT)

-Satisfy one of the following:

--Females: Non-pregnant and non-lactating; surgically sterile (e.g., tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy), post-menopausal (defined as 12 months of spontaneous amenorrhea in females >55 years of age or, in females less than or equal to 55 years, 12 months of spontaneous amenorrhea without an alternative medical cause and follicle-stimulating hormone (FSH) levels in the postmenopausal range for the laboratory involved), abstinent, or if engaged in sexual relations of child-bearing potential, patient is using an acceptable contraceptive method from time of signing the informed consent form until at least 13 weeks after the last dose of Study Drug administration.

--Males: Surgically sterile, abstinent, or if engaged in sexual relations with a female of child bearing potential, patient is utilizing an acceptable contraceptive method from the time of signing the informed consent form until at least 13 weeks after the last dose of study drug administration.

Note: Abstinence is only an effective method of birth control when this is the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods), declaration of abstinence for the duration of a trial and withdrawal are not acceptable methods of contraception.

EXCLUSION CRITERIA:

-A diagnosis of generalized lipodystrophy

-Current or history of autoimmune diseases (even with a diagnosis of PL) unless approved by the Investigator and Sponsor Medical Monitor

-Acute pancreatitis within 4 weeks of enrollment

-History within 6 months of enrollment of acute or unstable cardiac ischemia (myocardial infarction, acute coronary syndrome, new onset angina), stroke, transient ischemic attack, or unstable congestive heart failure requiring a change in medication

-Major surgery within 3 months of enrollment

-History of heart failure with New York Heart Association functional classification (NYHA) greater than Class II

-Uncontrolled hypertension (blood pressure [BP] >160/100 mm Hg)

-Any of the following laboratory values at enrollment:

--Cardiac troponin T >ULN

--Measured or estimated (in case of triglycerides > 400 mg/dL) LDL-C >130 mg/dL on maximal tolerated statin therapy

--Hemoglobin HbA1c greater than or equal to 9.5%

--Hepatic:

---Total bilirubin >ULN

---ALT >3.0 x ULN. Higher levels will be permitted after a safety review by a hepatologist, that includes no evidence of cirrhosis.
