Selected Recent Events

• Received Breakthrough Therapy designation from the U.S. Food and Drug Administration for ARO-AAT, also known as TAK-999, the company’s second-generation investigational RNA interference (RNAi) therapeutic being co-developed with Takeda Pharmaceutical Company Limited as a treatment for the rare genetic liver disease associated with alpha-1 antitrypsin deficiency.
• Presented additional positive interim 48-week liver biopsy results from the ongoing AROAAT2002 study, an open-label Phase 2 clinical study of ARO-AAT, at The International Liver Congress – The Annual Meeting of the European Association for the Study of the Liver (EASL). The results demonstrate that investigational ARO-AAT treatment led to improvements in multiple measures of liver health, including fibrosis, with substantial and sustained reductions in the level of mutant AAT protein. In addition, ARO-AAT treatment was generally well tolerated after up to 1 year of treatment.
• Presented positive interim results from AROHSD1001, an ongoing Phase 1/2 clinical study of ARO-HSD, the company’s investigational RNAi therapeutic being developed as a treatment for patients with alcohol-related and nonalcohol related liver diseases, such as nonalcoholic steatohepatitis (NASH), at EASL. The data demonstrate that ARO-HSD is the first investigational therapeutic to achieve robust reductions in messenger RNA and protein levels of hepatic HSD17B13, leading to reductions in alanine aminotransferase (ALT), a liver enzyme typically elevated in liver diseases including NASH.
• Announced positive interim results from the first two cohorts of AROHIF21001, a Phase 1b dose-finding clinical study of ARO-HIF2, the company’s investigational RNAi therapeutic being developed as a treatment for patients with clear cell renal cell carcinoma. The data show clear signs of meaningful target engagement and some potentially early signs of efficacy in at least one patient.
• Initiated and began dosing patients in AROANG3-2001, a Phase 2b clinical study of ARO-ANG3, the company’s investigational RNAi therapeutic being developed as a treatment for patients with mixed dyslipidemia.
• Initiated and began dosing patients in AROAPOC3-2001, a Phase 2b clinical study of ARO-APOC3, the company’s investigational RNA interference (RNAi) therapeutic being developed as a treatment for patients with severe hypertriglyceridemia (SHTG). Arrowhead also intends to initiate a Phase 2b study and a Phase 3 study of ARO-APOC3 in two additional patient populations in 2021.
• Announced a global collaboration and license agreement with Horizon Therapeutics for ARO-XDH, a previously undisclosed discovery-stage RNAi therapeutic being developed by Arrowhead as a potential treatment for people with uncontrolled gout. Arrowhead received $40 million as an upfront payment from Horizon and is eligible to receive up to $660 million in potential development, regulatory and commercial milestones, and is further eligible to receive royalties in the low- to mid-teens range on net product sales.
• Earned a $10 million option exercise fee from Janssen Pharmaceuticals, Inc., part of the Janssen Pharmaceutical Companies of Johnson & Johnson, for ARO-JNJ1.
• Presented promising preclinical data on ARO-DUX4, Arrowhead’s first muscle-targeted program being developed as a treatment for patients with facioscapulohumeral muscular dystrophy (FSHD) at the 28th Annual FSHD Society International Research Congress. The data show that the TRiM^TM muscle delivery platform achieved functional delivery to various types of skeletal muscle and achieved deep, durable, and dose-dependent knockdown of target genes. In addition, ARO-DUX4 improved multiple measures of FSHD-like muscle phenotype in relevant preclinical animal models.
• Nominated ARO-C3, which is designed to reduce production of complement component 3 (C3) as a potential treatment for various complement mediated diseases, as a clinical candidate and initiated IND-enabling toxicology studies.

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.
