Severe Hypertriglyceridemia

The purpose of this study is to evaluate the safety and efficacy of solbinsiran in lowering triglycerides and other lipid measures compared to placebo in participants with severe hypertriglyceridemia. Participants will receive two subcutaneous injections.

This study will evaluate the efficacy and safety of plozasiran in approximately 288 adult participants with severe hypertriglyceridemia (SHTG) and history of at least two prior acute pancreatitis (AP) events not attributed to other etiologies, with at least one occurring within the last 12 months prior to screening. Eligible participants will be randomly assigned in a double-blind manner to either receive plozasiran 25 mg by subcutaneous (SC) injection every three months (Q3M) or matching placebo. Enrolled participants will be counseled to remain on the specified low-fat diet and background medications throughout the study. Following completion of the double-blind treatment period, or if the participant has a positively adjudicated AP event (whichever occurs first), participants will transition to the 12-month Open-Label Extension (OLE) treatment period receiving plozasiran 25 mg by SC injection Q3M.

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 a multicenter, randomized, double-blind, placebo-controlled Phase 3 trial for adults with severe hypertriglyceridemia whose lipid levels remain uncontrolled under standard Icosapent Ethyl background treatment plus lifestyle management. Eligible participants complete a screening run-in period, then randomize equally to three treatment groups: two active DR10624 subcutaneous injection groups and one placebo group. All subjects maintain fixed oral background lipid therapy throughout long-term double-blind treatment, followed by a short safety follow-up period. The primary objective is to evaluate the triglyceride-lowering effect of DR10624 versus placebo. Secondary assessments include other lipid indicators, liver fat content, overall safety, and anti-drug antibody status. Independent committees monitor interim data and adjudicate key clinical events to ensure participant safety.
