Clinical Trial Summary

The purpose is to assess the Safety, Tolerability, and Pharmacodynamics effect of IONIS DGAT2Rx in up to 45 Adult Patients with Type 2 Diabetes.

Description:

This short-term study will assess changes in hepatic steatosis over a 13-week treatment period in a patient population with higher risk for development of Nonalcoholic fatty liver disease (NAFLD) and Nonalcoholic steatohepatitis (NASH), obese type 2 diabetes mellitus (T2DM) with elevated HbA1c.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Absolute Change in Liver Fat Percentage (Randomized Population)	Absolute change in liver fat percentage as quantified by magnetic resonance imaging-estimated proton density fat fraction (MRI-PDFF) from baseline to post-treatment MRI.	Baseline to Week 15
Primary	Absolute Change in Liver Fat Percentage (Per Protocol Population)	Absolute change in liver fat percentage as quantified by MRI-PDFF from baseline to post-treatment MRI.	Baseline to Week 15
Primary	Percentage of Participants With Adverse Events That Were Related to Treatment With IONIS DGAT2Rx	An adverse event (AE) is any unfavorable and unintended sign (including a clinically-significant abnormal laboratory finding, for example), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE is considered related to the investigational drug product.	Up to 176 days
Primary	Percentage of Participants With Adverse Events, Graded by Severity, That Were Related to Treatment With IONIS DGAT2Rx	AEs were graded according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03, June 2010. Grades: mild - the event is easily tolerated by the participant and does not affect the participant's usual daily activities; moderate - the event causes the participant more discomfort and interrupts the participant's usual daily activities; severe - the event is incapacitating and causes considerable interference with the participant's usual daily activities.	Up to 176 days
Secondary	Percent Change in Liver Fat Percentage	Relative percent change in liver fat percentage from baseline to post-treatment MRI.	Baseline to Week 15
Secondary	Percentage of Participants With = 30% Relative Reduction in Liver Fat Percentage	Percentage of participants with = 30% relative reduction in liver fat percentage from baseline to post-treatment.	Week 15
Secondary	Percent Change in Liver Volume	Assessed from Baseline MRI to Post-Treatment MRI.	Baseline to Week 15
Secondary	Percent Change in Plasma Lipoprotein Profile	Percent change in plasma lipoprotein profile (total cholesterol, apolipoprotein B [ApoB], high density lipoprotein (HDL), low density lipoprotein cholesterol [LDL-C], non-HDL, triglycerides, and very low density lipoproteins [VLDL]) from baseline to the average of the post-treatment values assessed 1 and 2 weeks after the last dose (Post-Treatment 1 and Post-Treatment 2 visits).	Week 15
Secondary	Percent Change in Parameters of Insulin Resistance (IR)	Percent change in parameters of IR (fasting plasma glucose [FPG], homeostatic model assessment - insulin resistance [HOMA-IR], and insulin) from baseline to post-treatment.	Week 14
Secondary	Absolute Change in Hemoglobin A1C (HbA1C)	Absolute change in HbA1C from baseline to post-treatment.	Week 14
