Rona Therapeutics Announces Breakthrough Data on Potential Annual Dosing RNAi Therapy RN026 Targeting Lipoprotein(a) in The National Lipid Association (NLA) Scientific Sessions 2025

SHANGHAI, May 29, 2025 /PRNewswire/ -- Rona Therapeutics, a global leading RNA therapy company, today announced preclinical data for its self-developed RNA interference (RNAi) therapy RN026 at the National Lipid Association (NLA) Annual Scientific Sessions. Preclinical studies revealed that the therapy, targeting lipoprotein(a) (Lp(a))—an independent risk factor for cardiovascular diseases—achieved a 99% reduction in Lp(a) with potential annual dosing regimen in non-human primate (NHP) study.

Key Highlights

1. Unparalleled Efficacy and Durability
   • In transgenic mouse models, a single 2mg/kg subcutaneous injection resulted in 98% reduction in serum Apo(a) protein, which lasted for at least 42 days 
   • In NHP study, a single 2mg/kg subcutaneous injection achieved maximum 99% reduction of serum Lp(a); 95% Lp(a) reduction was maintained at 98 days post-dose with ~80% serum Lp(a) decreasing effect sustained till 154 days, suggesting annual dosing potential in human
2. Precision siRNA Design
   • Targets multiple sites inside and outside of the KIV-2 CNV region to maximize knock-down efficiency
   • Very low hybridization related off-target risk
3. Dual Benefits
   • Accompanied by a 25% reduction in LDL-C levels in NHP study
   • Repeated dose tox studies in SD rats confirmed no adverse findings

About RN026

RN026 demonstrates tremendous potential as a breakthrough therapy in a range of cardiovascular diseases, i.e. ASCVD, aortic stenosis, peripheral arterial disease, with differentiated long-lasting efficacy, potent Lp(a) reduction, and excellent safety profile. There is approximately 10-20% world population that has elevated serum Lp(a) level. RN026 is poised to bring new therapeutic hope to cardiovascular patients globally.
