A Phase 2 interventional study of ION775 in Hypertriglyceridemia and Severe Hypertriglyceridemia, sponsored by Ionis Pharmaceuticals, Inc.. Recruiting at 18 sites in 2 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-02.
Sponsored by Ionis Pharmaceuticals, Inc. · Phase 2, Interventional, and Treatment
The main objective of this study is to evaluate the effect of ION775 on fasting triglyceride (TG) levels in participants with hypertriglyceridemia (HTG) and severe hypertriglyceridemia (sHTG).
This is an open-label, parallel-dose study consisting of a 4-6 week screening period, a 6-month treatment period and a 6-month post-treatment follow-up period.
324 studies on the registry are indexed under Hypertriglyceridemia; 38 are open to participants now.
This study's planned enrollment of 72 is close to the median of 66 across 288 interventional studies indexed under Hypertriglyceridemia.
Browse Hypertriglyceridemia studies →Ionis Pharmaceuticals, Inc. is the lead sponsor of 118 studies on the registry; 10 are open to participants now.
Of its 49 completed or terminated interventional studies of FDA-regulated products, 22 (45%) have results posted.

Key Inclusion Criteria:
Key Exclusion Criteria:
Note: Other protocol pre-specified inclusion/exclusion criteria may apply.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
