Study to Assess the Effects of Mipomersen on Lipid and Lipoprotein Metabolism in Healthy Subjects

The primary objective of this Phase I exploratory study is to determine the effects of mipomersen on the hepatic production of apolipoprotein-B (apo B) in very low density lipoprotein (VLDL) compared to baseline levels. The study will consist of a Screening Period, a 1-week Run-in Period to establish a stable diet, an approximate 11-week Treatment Period with Placebo or Mipomersen, and a 25-week Post-Treatment Follow-up Period. The total duration of any given subject's participation will be approximately 40 weeks.

Inclusion criteria

  • Non-pregnant, non-lactating, surgically sterile, postmenopausal, abstinent, or the subject or partner is compliant with an acceptable contraceptive regimen for 4 weeks prior to Screening and willing to remain compliant with the contraceptive regimen throughout treatment and for 25 weeks after the last investigational product dose
  • Body weight >50 kg, body mass index (BMI) ≤38 kg/m2, and stable weight (i.e., within 5% of mean body weight) for > 8 weeks prior to Screening
  • Fasting TG levels of ≤170 mg/dL, fasting serum blood glucose of ≤115 mg/dL, and an HbA1c ≤6.5%

Exclusion criteria

  • Presence of any clinically significant abnormal laboratory profiles, physical exams, vital signs, or ECGs
  • History or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, infectious, or psychiatric disease
  • Malignancy (with the exception of basal or squamous cell carcinoma of the skin if adequately treated and no recurrence for >1 year) at Screening
  • History of relevant food and/or drug allergies (i.e., allergy to heparin or any significant food allergy that could preclude a stable diet)
  • The subject is receiving prescription lipid-lowering therapies such as statins, bile acid sequestrants, niacin/nicotinic acid, and/or fibrates or over-the-counter (OTC) fish oils, flaxseed, red rice or nutrient supplements that might affect lipid levels
  • The subject is unwilling to limit alcohol consumption for the entire duration of the study
  • The subject smokes >5 cigarettes per day
