Официальное название

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase III Trial to Evaluate the Efficacy and Safety of DR10624 in Subjects With Severe Hypertriglyceridemia Receiving Stable Lipid-Modifying Therapy

Обзор

This is a multicenter, randomized, double-blind, placebo-controlled Phase 3 clinical trial to assess the efficacy and safety of weekly subcutaneous DR10624 injection in adult patients with severe hypertriglyceridemia (sHTG). Eligible participants have persistently elevated fasting triglycerides despite stable background lipid-lowering therapy. Subjects will be randomized at a 2:2:1 ratio to three treatment arms: DR10624 low dose, DR10624 high dose, or matching placebo, receiving weekly subcutaneous injections for a total of 64 weeks double-blind treatment, followed by a 4-week post-treatment safety follow-up. The primary goal is to evaluate the percentage reduction in fasting triglycerides at Week 26. Secondary assessments include changes in ApoC3, remnant cholesterol, liver fat content measured by MRI-PDFF, incidence of adjudicated acute pancreatitis, and overall safety profile including treatment-emergent adverse events and immunogenicity.

Вмешательства

• Биопрепарат DR10624 Injection
  Novel investigational biologic agent for severe hypertriglyceridemia, administered via weekly subcutaneous injection with two titrated dose regimens (low-dose and high-dose) for 64 weeks double-blind treatment period.
• Другое Matching Placebo for DR10624
  Volume-matched inert subcutaneous injection placebo, visually identical to DR10624 to maintain double-blind masking for all study participants.
