Official Title

A Randomized, Double Blind, Placebo-Controlled Study to Assess Efficacy, Safety and Tolerability of ISIS 304801 in Patients With Partial Lipodystrophy With an Open-Label Extension

Brief Summary


      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.


      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.


      Adults at least 18 years old with partial lipodystrophy.


      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.


      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.


Detailed Description


      Lipodystrophy is a rare disease of deficient adipose mass, characterized by severe
      hypertriglyceridemia as well as insulin resistance, diabetes mellitus, fatty liver disease,
      acute pancreatitis, and early cardiovascular events. Apolipoprotein C-III (apoC-III)
      regulates triglyceride metabolism, and apoC-III levels strongly correlate with serum
      triglycerides in a variety of patient populations. Patients with genetically low levels of
      apoC-III have lower triglycerides and reduced cardiovascular disease, while individuals with
      genetically elevated levels of apoC-III have higher triglycerides and increased non-alcoholic
      fatty liver disease and insulin resistance. Pharmacologic reduction of apoC-III using
      anti-sense oligonucleotides (ASOs) reduce triglycerides by ~60-70% in a tested patient


      The purpose of this study is to determine if apoC-III reduction using an ASO to apoC-III
      (ISIS 304801) will reduce triglycerides and improve insulin resistance, diabetes, and hepatic
      steatosis in patients with lipodystrophy.

      The primary hypothesis to be tested is:

        1. ISIS 304801will reduce log10 fasting serum triglycerides.

           Secondary and tertiary hypotheses to be tested are:

        2. ISIS 304801will improve glucose metabolism by improving insulin resistance.

        3. ISIS 304801 will reduce hepatic steatosis.

        4. ISIS 304801 will improve cardiovascular risk markers.

      We will also explore the mechanism of action of apoC-III ASO by studying lipoprotein lipase
      activity and lipoprotein particle distribution.


      This study will enroll up to 20 patients with partial lipodystrophy with a goal of 10 study
      completers. The study will be conducted in two phases. The first is a 16-week, randomized,
      double-blind, placebo-controlled design. Subjects will be treated with ISIS 304801 at a
      target dose of 300 mg per week or placebo. Following this phase, all subjects will enter a 12
      month open-label extension in which they will receive active drug. Patients who experience
      benefit (triglyceride lowering greater than or equal to 50%) may receive an additional 12
      months of open-label drug (up to 24 months, total). Measurement of the primary outcome (serum
      triglycerides) and key secondary outcomes will be performed at baseline prior to the
      intervention, after 13 weeks (primary outcome only) or 16 weeks (primary and secondary
      outcomes) of blinded drug or placebo, and after an additional 4 months of active drug in
      subjects initially randomized to placebo.
