Selected Recent Events

• Continued to build the cardiometabolic vertical to include two new additional complementary medicines designed to treat obesity and metabolic disease, both of which are on schedule for clinical trial application (CTA) filings before the end of 2024
  • ARO-INHBE utilizes the liver targeted TRiM™ platform and targets the INHBE gene. INHBE expression is increased in obesity and INHBE loss-of-function variants identified in human genetic databases are protective of type 2 diabetes and are associated with reduced visceral fat and a reduced waste to hip ratio
  • The second is based on Arrowhead’s adipose tissue targeting TRiM™ platform and addresses an undisclosed gene target
• Performed a portfolio review and R&D organization restructuring resulting in key changes, including:
  • Arrowhead will focus investment in late-stage clinical development and build out commercial infrastructure to support sales and marketing of medicines primarily in the cardiometabolic and pulmonary verticals
  • Engaged Bruce Given, M.D., Arrowhead’s former chief operating officer and head of R&D for Arrowhead for several years before his retirement in 2020 after a more than 30-year career in biotechnology and pharmaceutical research, development, and sales and marketing, on an interim basis to serve as chief medical scientist to help with restructuring efforts and the process to recruit new therapeutic area experts to decentralize the chief medical officer function
  • Identified opportunities to reduce forward operating cash burn guidance by up to $100 million, approximately $30 million per quarter, while retaining full funding and investment in core cardiometabolic and pulmonary programs
  • Focused R&D spending for non-core programs on development activities that advance candidates to an attractive stage for potential partnerships
  • Terminated development of ARO-SOD1 and HZN-457
• Strengthened the balance sheet through an underwritten registered offering of common stock gross proceeds of approximately $450 million, before deducting underwriting discounts, commissions, and other offering expenses payable by the company
• Presented data on cardiometabolic pipeline at the American Heart Association Scientific Sessions in November 2023
  • Presented new Phase 2 clinical data from the ongoing SHASTA-2 and MUIR studies of plozasiran (ARO-APOC3) and the ARCHES-2 study of zodasiran (ARO-ANG3)
  • Hosted a webinar to discuss plozasiran featuring experts in the treatment and management of lipid and lipoprotein disorders
• Completed chronic GLP toxicology for pulmonary candidates ARO-RAGE, designed to reduce expression of the receptor for advanced glycation end products as a potential treatment for inflammatory pulmonary diseases, and ARO-MMP7, designed to reduce expression of matrix metalloproteinase 7 as a potential treatment for idiopathic pulmonary fibrosis
  • Results were highly encouraging and suggest sufficient safety margins to proceed to Phase 2 studies
• Filed for regulatory clearance to initiate a Phase 1/2a study of ARO-CFB, Arrowhead’s RNAi therapeutic candidate for patients with complement renal disease such as immunoglobulin A nephropathy (IgAN), which is the world’s most common glomerular disease
• Filed for regulatory clearance to initiate a Phase 1/2a study of Arrowhead’s second RNAi therapeutic candidate targeting skeletal muscle, ARO-DM1, for patients with type 1 myotonic dystrophy

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.
