Prediction of Interspecies Translation for Targeting Delivery Coefficients of GalNAc-siRNA Silencing Apolipoprotein C-III Using a Mechanistic Minimal Physiologically Based Pharmacokinetic/Pharmacodynamic Model. (PubMed, Clin Pharmacokinet) - "This study successfully constructed the mPBPK-PD model and conducted interspecies extrapolation for a GalNAc-siRNA targeting APOC3. Promising quantitative insights into a hepatic-targeted GalNAc-siRNA delivery system are provided to characterize the unique temporal disconnection of PK/PD properties and evaluate the key in vivo delivery processes. It will promote model-informed strategies and quantitative mechanistic understanding to support efficient drug development, evaluation, and clinical application of this modality in the future."

Ribo’s siRNA asset RBD5044 receives Clinical Trial Authorization from Swedish MPA for a Phase II trial in patients with mixed dyslipidemia - "Ribocure Pharmaceuticals AB and Suzhou Ribo Life Science Ltd (Ribo) received authorization from the Swedish Medicinal Product Agency (MPA), to initiate a Phase II clinical trial in Sweden with the lipid-lowering siRNA drug RBD5044 that targets APOC3. The trial will evaluate efficacy and safety in patients with mixed dyslipidemia. A randomized, double-blind, placebo-controlled, multi-center phase II trial evaluating the efficacy and safety of RBD5044 in participants with mixed dyslipidemia will be run. The trial sites include Ribocure Clinic, a specialized phase II unit for high quality functional imaging proof of principle trials, based in GoCo Health Innovation City, Gothenburg, as well as sites in Lund and Uppsala, Sweden."

Combination therapy with GalNAc-siRNA drugs targeting both PCSK9 and APOC3 resulted in enhanced lipid lowering in mice (ESC 2024) - "Conclusions- The combination of RBD7022 targeting PCSK9 and RBD5044 targeting APOC3 simultaneously reduce LDL-C and TC levels. The combination of RBD7022 and RBD5044 could be a better therapeutic option to further reduce LDL-C, particularly for mixed hyperlipidemia patients and other high-risk individuals with both high LDL-C and high TG levels."
