Selected Recent Events

• Announced topline results with Takeda from the Phase 2 SEQUOIA clinical study of investigational fazirsiran for the treatment of liver disease associated with alpha-1 antitrypsin deficiency and provided an outline of a Phase 3 study that was co-developed by Takeda and Arrowhead and will be conducted by Takeda. Key results from SEQUOIA included the following:
  • Fibrosis regression observed in 50% of patients receiving fazirsiran
  • Median reductions of 94% of Z-AAT accumulation in the liver and mean reduction of 68% in histologic globule burden
  • Treatment emergent adverse events were generally well balanced between fazirsiran and placebo groups
  • Results consistent with AROAAT-2002 open-label study previously published in The New England Journal of Medicine
• Earned a $25 million milestone payment from Amgen after the first subject was enrolled in Amgen’s Phase 3 trial of olpasiran for the treatment of cardiovascular disease
• Earned a $15 million milestone payment from Horizon Therapeutics after the first subject was enrolled in Horizon’s Phase 1 study of HZN-457, formerly called ARO-XDH, for the treatment of gout
• Initiated dosing in AROMMP7-1001 (NCT05537025), a Phase 1/2a single ascending dose and multiple ascending dose clinical study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ARO-MMP7, an investigational RNAi therapeutic designed to reduce expression of matrix metalloproteinase 7 (MMP7) as a potential treatment for idiopathic pulmonary fibrosis (IPF), in up to 56 healthy volunteers and in up to 21 patients with IPF
• Presented interim data on the cardiometabolic pipeline in three late-breaking oral presentations at the American Heart Association (AHA) Scientific Sessions 2022 and at a virtual analyst and investor event. Key results included the following:
  • ARO-APOC3, an investigational RNAi therapeutic targeting apolipoprotein C-III (APOC3) being developed as a treatment for patients with cardiovascular disease, severe hypertriglyceridemia (SHTG), and familial chylomicronemia syndrome (FCS), decreased triglycerides by 86%, and non-HDL-C by 45% while increasing HDL-C by 99% in patients with severe hypertriglyceridemia
  • ARO-ANG3, an investigational RNAi therapeutic designed to silence the hepatic expression of angiopoietin-like protein 3 (ANGPTL3) being developed as a treatment for patients with heterozygous and homozygous familial hypercholesterolemia (HeFH and HoFH), decreased triglycerides by 59%, LDL-C by 32%, and was associated with a relative reduction in liver fat fraction in patients with mixed dyslipidemia
  • Olpasiran, which was originally developed by Arrowhead using its proprietary Targeted RNAi Molecule (TRiM™) platform and licensed to Amgen in 2016 and is designed to lower levels of lipoprotein(a) (Lp(a)), a genetically-determined independent risk factor for cardiovascular disease, reduced Lp(a) levels by more than 95% in patients with established atherosclerotic cardiovascular disease. These data were simultaneously published in the New England Journal of Medicine (NEJM)
• Strengthened the balance sheet with the sale of Arrowhead’s royalty interest in olpasiran to Royalty Pharma for:
  • $250 million in cash upfront
  • Up to $160 million in additional payments contingent on the achievement of certain clinical, regulatory, and sales milestones
  • Retained rights to $400 million in development, regulatory, and sales milestone payments potentially due from Amgen from the 2016 out-licensing agreement

Selected Fiscal 2023 First Quarter Financial Results

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.
