• Use of Mipomersen within 5 months of screening
• NYHA III or IV heart failure, or last known left ventricular ejection fraction < 30%

• Known active infection or major hematologic, renal, metabolic, gastrointestinal or endocrine dysfunction in the judgment of the investigator
• Diagnosis of deep vein thrombosis or pulmonary embolism within 3 months prior to enrollment
• Unreliability as a study participant based on the investigator's (or designee’s) knowledge of the subject (eg, alcohol or other drug abuse, inability or unwillingness to adhere to the protocol, or psychosis)
• Currently enrolled in another investigational device or drug study, or less than 30 days since ending another investigational device or drug study(s), or receiving other investigational agent(s)

• Subject will not be available for protocol-required study visits or procedures, to the best of the subject and investigator’s knowledge.
• Subject has any kind of disorder that, in the opinion of the investigator, may compromise the ability of the subject to give written informed consent and/or to comply with all required study procedures.
