Targeted RNAi Molecule Platform (TRiMTM)
Arrowhead's Targeted RNAi Molecule platform, or TRiMTM, utilizes ligand-mediated delivery and is designed to enable multi-tissue targeting, while being structurally simple. Active targeting has been core to Arrowhead's development strategy and the TRiMTM platform builds on more than a decade of work on actively targeted drug delivery vehicles. Arrowhead scientists now have the ability to progressively "TRiM" away extraneous features and chemistries and retain optimal pharmacologic activity.
New drug candidates utilizing this technology can achieve high levels of target gene knockdown, without an active endosomal escape component, as was required with prior technology platforms.
The TRiMTM platform represents an evolution in RNAi therapeutics from biologic complexity to small molecule precision and execution. The TRiMTM platform comprises the following components optimized, as needed, for each drug candidate: high affinity targeting ligands; various linker chemistries; structures that enhance pharmacokinetics; and highly potent RNAi triggers with sequence specific stabilization chemistries. The platform offers several competitive advantages, including:
- Simplified manufacturing at reduced cost
- Multiple routes of administration (subcutaneous, intravenous, and inhaled)
- Faster time to clinical candidates
- Wide safety margins
- Promise of taking RNAi to tissues beyond the liver
Arrowhead believes that for RNAi to reach its true potential, it must target organs outside the liver. Arrowhead is leading this expansion with the TRiMTM platform that holds the promise of reaching multiple tissues, including the lung and tumors. ARO-Lung1, the first candidate against an undisclosed gene target in the lung, reached almost 90% target knockdown following inhaled administration in rodents. In addition, the ARO-HIF2 candidate targeting renal cell carcinoma achieved 85% target gene knockdown in a rodent tumor model. Clinical Trial Authorization (CTA) filings are planned in Q4 2018 and in 2019 for ARO-Lung1 and ARO-HIF2, respectively.
ARO-AAT, Arrowhead's second generation subcutaneously administered clinical candidate for the treatment of alpha-1 antitrypsin deficiency liver disease, achieved up to 92% knockdown in monkeys, thought to be near complete suppression of hepatic production of the alpha-1 antitrypsin protein. In non-GLP rat and monkey exploratory toxicology studies, no changes in clinical chemistries were observed and no histopathology suggestive of organ toxicity at doses up to 300 mg/kg (100x expected human dose). Arrowhead plans to file a CTA in Q1 2018 to initiate clinical studies, pending completion of GLP toxicology studies.
ARO-HBV, Arrowhead's third generation subcutaneously administered clinical candidate for the treatment of chronic hepatitis B virus infection, achieved up to 99.9% knockdown of hepatitis B surface antigen (HBsAg), e-antigen (HBeAg), and HBV DNA in rodent models. In a non-GLP rat exploratory toxicology study, no changes in clinical chemistries or histopathology changes suggestive of organ toxicity were observed at doses up to 300 mg/kg (75-100x expected human dose). Arrowhead plans to file a CTA in Q2 2018 to initiate clinical studies, pending completion of cross-reactivity and GLP toxicology studies.
ARO-APOC3 and ARO-ANG3
Arrowhead is expanding its cardiovascular disease portfolio utilizing the TRiM™ platform. Added to existing programs, ARO-LPA and ARO-AMG1, both partnered with Amgen; will be ARO-APOC3, targeting apolipoprotein C-III, and ARO-ANG3, targeting angiopoietin-like protein 3 (ANGPTL3). ARO-APOC3 and ARO-ANG3 will both be developed for the treatment of hypertriglyceridemia. CTA filings are planned for one or both candidates by the end of 2018.
