E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of ISIS 678354 as compared to placebo on the percent change in fasting triglycerides (TG) from Baseline |
|
E.2.2 | Secondary objectives of the trial |
• Proportion of patients who achieve ≥ 40% reduction in fasting TG from Baseline • Percent change in fasting apoB-48 from Baseline • Proportion of patients who achieve fasting TG ≤ 750 mg/dL (8.4 mmol/L) • Adjudicated acute pancreatitis event rate in patients with ≥ 2 events of adjudicated acute pancreatitis in 5 years prior to enrollment • Adjudicated acute pancreatitis event rate • Proportion of patients who achieve ≥ 70% reduction in fasting TG from Baseline • Proportion of patients who achieve fasting TG ≤ 500 mg/dL (5.7 mmol/L)
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• A diagnosis of genetically confirmed Familial Chylomicronemia Syndrome (type 1 Hyperlipoproteinemia) • Fasting TG ≥ 880 mg/dL (10 mmol/L) at Screening • History of pancreatitis. Patients without a documented history of pancreatitis are also eligible but their enrollment will be capped at 35%
|
|
E.4 | Principal exclusion criteria |
• Acute coronary syndrome within 6 months of Screening • Major surgery within 3 months of Screening • Active pancreatitis within 4 weeks of Screening • Platelet count < 100K/mm3 at Screening or Qualification. • Have any other conditions, which, in the opinion of the Investigator would make the patient unsuitable for inclusion, or could interfere with the patient participating in or completing the study

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
