Material Changes and Clinical Data
The primary material change is the regulatory approval of TRYNGOLZA for the treatment of severe hypertriglyceridemia (sHTG). Key clinical data supporting this approval includes:

- Efficacy (CORE and CORE2 Studies):
- Lowered fasting triglyceride levels by up to 72% compared to placebo at six months, sustained at 12 months.
- Reduced acute pancreatitis events by up to 91%.
- 86% of patients achieved TG levels below 500 mg/dL.
- Number Needed to Treat (NNT) to prevent one episode of acute pancreatitis over one year was 20 overall, and 4 in the highest-risk subgroup (TG ≥ 880 mg/dL with prior history).
- Safety: Most common adverse reactions (incidence ≥2% higher than placebo) were injection site reactions and liver enzyme increases.
