Arrowhead Pharmaceuticals Initiates Phase 3 YOSEMITE Study of Investigational Zodasiran for the Treatment of Homozygous Familial Hypercholesterolemia (Businesswire) - "Arrowhead Pharmaceuticals...announced that it has dosed the first subject in the YOSEMITE Phase 3 clinical trial of zodasiran, the company’s investigational RNA interference (RNAi) therapeutic being developed as a potential treatment for homozygous familial hypercholesterolemia (HoFH), a rare genetic condition that leads to severely elevated LDL-cholesterol and early onset cardiovascular disease. Zodasiran is the fourth investigational RNAi-based candidate developed by Arrowhead to reach late-stage pivotal studies, after investigational drugs plozasiran, fazirsiran (licensed to Takeda) and olpasiran (licensed to Amgen)....YOSEMITE (NCT07037771) is a Phase 3 multicenter, randomized, placebo-controlled study to evaluate the efficacy and safety of zodasiran in adolescent and adult patients with genetically or clinically diagnosed homozygous familial hypercholesterolemia (HoFH) on maximally tolerated lipid lowering therapy."

ANGPTL3: A Breakthrough Target in Treatment for Dyslipidemia and Atherosclerosis. (PubMed, J Atheroscler Thromb) - "Despite conventional treatment with statins, ezetimibe, or PCSK9 inhibitors, there are cases of familial hypercholesterolemia (FH) in which LDL-C levels cannot be sufficiently lowered to the target level, resulting in failure to prevent CVD...In fact, evinacumab, an anti-ANGPTL3 monoclonal antibody, has been shown to substantially reduce LDL-C and TG levels, even in FH patients with LDL receptor gene mutations who are resistant to the conventional treatments described above. Clinical trials have also shown that siRNA therapeutics, such as zodasiran and solbinsiran, improve lipid profiles in patients with dyslipidemia. Recently, we have begun developing a peptide-based anti-ANGPTL3 vaccine and confirmed in a preclinical FH mouse model that it significantly decreases LDL-C and TG levels, reduces atherosclerotic lesions and maintains long-term efficacy without adverse effects. In this review, we discuss the promising advances in ANGPTL3-targeted therapeutics that may..."

Small Interfering RNA (siRNA) in Dyslipidemia: A Systematic Review on Safety and Efficacy of siRNA. (PubMed, J Exp Pharmacol) - "Inclisiran led to a notable 44.09% reduction in LDL and 37.5% in apolipoprotein levels among individuals with hypercholesterolemia. In hyperlipoproteinemia(a), therapies like Lepodisiran and Olpasiran achieved a 75.69% drop in apolipoproteins and 16.25% in LDL. For hypertriglyceridemia, agents such as ARO-APOC3 and Plozasiran showed over 50% reductions in both VLDL and triglycerides...In conclusion, the benefits of siRNA therapy in dyslipidemia management appear to outweigh its potential drawbacks, demonstrating promising efficacy and safety profiles. However, further research is necessary to fully understand its long-term effects and optimize its therapeutic potential."

Novel Therapeutics for Familial Chylomicronemia Syndrome. (PubMed, Curr Atheroscler Rep) - "Volanesorsen, an ASO targeting APOC3, has shown effectiveness in managing FCS, multifactorial chylomicronemia, and familial partial lipodystrophy, but its use is limited by thrombocytopenia. Emerging therapies, Olezarsen (ASO anti-APOC3) and Plozasiran (siRNA anti-APOC3), both conjugated with GalNAc, show promise in reducing acute pancreatitis risk without platelet concerns. ANGPTL3 inhibition requires residual lipoprotein lipase (LPL) activity, with only siRNA-based therapies-zodasiran and solbinsiran-under investigation. Suppressing APOC3 expression and targeting ANGPTL3 via siRNA offer significant potential, but long-term studies are needed to confirm their efficacy and safety. Future research may explore gene-editing strategies using lipid nanoparticle-based CRISPR-Cas9 delivery for more durable treatment outcomes."

Comprehensive evaluation of siRNA therapeutics on Lp(a): A network meta-analysis. (PubMed, Diabetes Obes Metab) - "Lp(a)-targeted siRNA agents have shown robust effectiveness in substantially reducing Lp(a) levels, including both percentage and absolute reductions, with moderate improvements in LDL-C and apo(B) concentrations. Non-Lp(a)-targeted siRNA agents also demonstrate modest reductions in Lp(a) levels. The safety profile is generally favourable, but zerlasiran and inclisiran may increase the incidence of injection-site reactions."

Current and Emerging Treatment Options for Hypertriglyceridemia: State-of-the-Art Review. (PubMed, Pharmaceuticals (Basel)) - "Among apolipoprotein C-III (apoC-III) inhibitors, olezarsen and plozasiran appear to be safer alternatives for volanesorsen regarding the risk of drug-induced thrombocytopenia in patients with FCS or severe HTG. After the failure of vupanorsen, a new angiopoietin-like protein 3 (ANGPTL3) inhibitor, zodasiran, demonstrated the potential to decrease TG levels in patients with moderate HTG. Meanwhile, the fibroblast growth factor 21 (FGF21) analog, pegozafermin, became another candidate for the treatment of severe HTG. This comprehensive review outlines pharmacological targets in TG-rich lipoprotein metabolism, discusses international guidelines, and summarizes the latest evidence from clinical trials to provide insight into the current and emerging treatment options for primary HTG."
