“As a physician, I have seen firsthand how challenging it can be for patients with sHTG to lower their triglycerides below 500 mg/dL, despite background lipid-lowering therapies and lifestyle changes, which leaves them at risk of a devastating and potentially life-threatening acute pancreatitis attack. TRYNGOLZA is a transformational new therapy that showed unprecedented, clinically meaningful outcomes for sHTG, with the potential to redefine the treatment paradigm.”

“Acute pancreatitis is a painful and potentially life-threatening condition that often requires urgent hospitalisation. People with triglyceride levels above 10 mmol/L have a four times greater risk of acute pancreatitis compared to those with ideal low levels, and this risk increases progressively as triglyceride levels rise. According to EAS/ESC guidelines, triglyceride levels above 10 mmol/L warrant urgent intervention to prevent acute pancreatitis.”

“These results add to the collective body of evidence for olezarsen, showing the reduction of acute pancreatitis risk in severe hypertriglyceridemia. As rates of acute pancreatitis continue to increase, olezarsen has the potential to be an important part of a preventative approach to disease management in at-risk patients.”

Overview

Expands targeted apoC-III inhibition beyond rare familial syndromes to broader severe.

Key Points

  • To summarize the FDA approval of olezarsen (Tryngolza) for the management of severe hypertriglyceridemia and reduction of acute pancreatitis risk in adults.
  • Evaluation of regulatory data leading to FDA approval of olezarsen, a subcutaneously injected apolipoprotein C-III-directed antisense oligonucleotide.
  • Contextual assessment of olezarsen alongside existing apoC-III-targeted therapies such as plozasiran for severe lipid disorders.
  • Olezarsen received approval to reduce triglyceride levels and acute pancreatitis risk in adult patients with severe hypertriglyceridemia.
  • The therapy expands upon earlier indications for familial chylomicronemia syndrome established by olezarsen and plozasiran.

Structured PICO

Does olezarsen reduce triglyceride levels and the risk of acute pancreatitis in adults with severe hypertriglyceridemia?

P
Population
Adults with severe hypertriglyceridemia and adults with familial chylomicronemia syndrome (FCS)
I
Intervention
Olezarsen (subcutaneously injected apolipoprotein C-III-directed antisense oligonucleotide)
O
Outcome
Reduction in triglyceride levels and risk of acute pancreatitis

The FDA has approved olezarsen, an apoC-III-directed antisense oligonucleotide, for the treatment of severe hypertriglyceridemia to reduce triglycerides and acute pancreatitis risk.

Cite This Study

A 2026 study studied Severe hypertriglyceridemia. Olezarsen was evaluated on Triglyceride levels and risk of acute pancreatitis. The FDA approved olezarsen, a subcutaneous apoC-III-directed antisense oligonucleotide, to reduce triglyceride levels and acute pancreatitis risk in adults with severe hypertriglyceridemia.
