- None.
- None.
- Plozasiran achieved mean max reductions of up to
- In patients with mixed dyslipidemia, mean max reduction in APOC3 was up to
- Company will host a virtual analyst and investor event today, November 13, 2023, at 4:30 pm ET
“The compelling data presented today at AHA support the further development of plozasiran in Phase 3 studies, including in patients with severe hypertriglyceridemia (SHTG), and potentially in a clinical outcomes trial for patients with increased risk for atherosclerotic cardiovascular disease (ASCVD) due to elevated triglyceride rich lipoproteins (TRLs),” said Christie M. Ballantyne, M.D., Baylor College of Medicine. “Numerous epidemiologic studies have shown an association between higher TRLs and an increased risk of ASCVD. Despite potent LDL-C lowering therapies, residual ASCVD risk persists due in part to high levels of atherogenic TRLs. Importantly, plozasiran is the first investigational RNAi-based molecule to demonstrate substantial reductions in TRLs in a mixed dyslipidemia population.”
Plozasiran Data
In the Phase 2 SHASTA-2 study of plozasiran in 226 subjects with SHTG who had baseline triglycerides (TGs) of greater than 500 mg/dL, two doses of 10 mg, 25 mg, or 50 mg of plozasiran once every 12 weeks reduced TGs to near normal levels and achieved TG levels below the risk threshold for acute pancreatitis (less than 500 mg/dL) in over
Plozasiran continues to show a favorable safety profile to date. Treatment emergent adverse events (TEAEs) reported to date reflect the comorbidities and underlying conditions of the study population. Serious TEAEs were not related to plozasiran and were resolved without sequelae, except two subjects with malignancies.
In the Phase 2 MUIR study of plozasiran in 353 subjects with mixed dyslipidemia who had fasting TGs between 150-499 mg/dL and either LDL-cholesterol greater than 70 mg/dL or non-HDL-cholesterol greater 100 mg/dL, two doses of 10 mg, 25 mg, or 50 mg of plozasiran once every 12 weeks or once every 24 weeks silenced APOC3 and demonstrated robust reductions in atherogenic lipoproteins. At 24 weeks, plozasiran reduced TGs to -
TEAEs reported to date reflect the comorbidities and underlying conditions of the study population. Most serious TEAEs recovered with no sequelae.

Zodasiran Data
In the Phase 2 ARCHES-2 study of zodasiran in 204 subjects with mixed dyslipidemia who had fasting TGs between 150-499 mg/dL and either LDL-cholesterol greater than 70 mg/dL or non-HDL-cholesterol greater 100 mg/dL, two doses of 50 mg, 100 mg, or 200 mg of zodasiran once every 12 weeks silenced the expression of angiopoietin-like protein 3 (ANGPTL3) and decreased atherogenic lipoproteins. Treatment with zodasiran resulted in substantial reductions of ANGPTL3 up to -
ARO-ANG3 was also associated with a relative reduction in liver fat fraction at week 24, with no adverse events related to liver function test changes reported to date. ARO-ANG3 TEAEs reported to date are consistent with those expected in this patient population and with associated underlying comorbidities.

Virtual Analyst and Investor Event
The company is hosting a virtual analyst and investor event today, November 13, 2023, at 4:30 pm ET featuring key opinion leaders who will discuss the plozasiran data and its potential as a treatment for SHTG and mixed dyslipidemia in patients with ASCVD. To register for the event, please visit: https://lifescievents.com/event/arrowhead/.
The analyst and investor event will feature presentations from Arrowhead management and three experts in the treatment and management of lipid and lipoprotein disorders:
-
Daniel Gaudet, MD, PhD, Professor of Medicine at Université de
Montréal , who will discuss plozasiran in the context of the current treatment landscape for severe hypertriglyceridemia -
Børge Nordestgaard, MD, Professor & Chief Physician, Copenhagen University Hospital, University of
Copenhagen, Denmark , who will discuss remnant cholesterol and its role in cardiovascular disease - Steven Nissen, MD, Chief Academic Officer for the Heart and Vascular Institute at the Cleveland Clinic, who will discuss the potential of a cardiovascular outcomes study of plozasiran
A copy of the presentation materials and a webcast link for the analyst and investor event will be available on the Events and Presentations page under the Investors section of the Arrowhead website.
About Arrowhead Pharmaceuticals
Arrowhead Pharmaceuticals develops medicines that treat intractable diseases by silencing the genes that cause them. Using a broad portfolio of RNA chemistries and efficient modes of delivery, Arrowhead therapies trigger the RNA interference mechanism to induce rapid, deep, and durable knockdown of target genes. RNA interference, or RNAi, is a mechanism present in living cells that inhibits the expression of a specific gene, thereby affecting the production of a specific protein. Arrowhead’s RNAi-based therapeutics leverage this natural pathway of gene silencing.
