Confirmed reduction in fasting plasma glucose (FPG) of >40 mg/dL (>2.2 mmol/L) at the Pre-treatment Visit (Week-1, Day-7) compared to a FPG value taken during the Screening Period; or fasted self-monitored plasma glucose (SMPG) values <140 mg/dL for >75% of measurements collected during Week -3 through Week -2
9. History of diabetic ketoacidosis
10. Treatment with lipid lowering therapy with the exception of statins. Statins are allowed at stable doses (≥3 months) prior to Screening and within the dose levels listed below. Other statin regimens should be discussed with the Sponsor Medical Monitor or designee
• Simvastatin at ≤40 mg/day
• Atorvastatin, fluvastatin, or lovastatin at ≤20 mg/day
• Rosuvastatin or pravastatin at ≤10 mg/day
• Pitavastatin at ≤2 mg/day

15. Treatment with any non-ISIS oligonucleotide (including siRNA) at any time or prior treatment with an ISIS oligonucleotide within 9 months of Screening. Patients who have previously received only a single dose of an ISIS-oligonucleotide as part of a clinical study may be included as long as a duration of ≥4 months has elapsed since dosing
16. Known history of or positive test for human immunodeficiency virus (HIV), hepatitis C or chronic hepatitis B
