Arrowhead Pharmaceuticals Reports 2024 Fiscal Year-End Results
Conference Call and Webcast Today, November 26, 2024 at 4:30 p.m. ET

PASADENA, Calif., November 26, 2024 — Arrowhead Pharmaceuticals, Inc. (NASDAQ: ARWR) today announced financial results for its 2024 fiscal year ended September 30, 2024. The Company is hosting a conference call today, November 26, 2024, at 4:30 p.m. ET to discuss the results.
“Arrowhead is well positioned, both individually and with partners, to advance and ultimately commercialize important new medicines using our proprietary TRiMTM technology. We have the potential to impact the lives of millions of patients in need. We believe we now have all the necessary pieces in place to drive significant value for shareholders in the short-term, mid-term, and, more importantly, over the long-term as we seek to build a sustainable, financially sound business,” said Christopher Anzalone, Ph.D., President and CEO at Arrowhead. “Key events have occurred during the recent period that we see as potentially transformational for Arrowhead. Earlier this month, we submitted our first NDA to the U.S. FDA for investigational plozasiran, paving the way for Arrowhead to potentially launch our first commercial product in 2025, subject to FDA review and approval. We also took steps to meaningfully strengthen our balance sheet, including entering into a large licensing and collaboration agreement with Sarepta Therapeutics, which was announced today. Sarepta is an important new partner with extensive clinical, regulatory, and commercial expertise and this collaboration will help us advance and commercialize multiple promising Arrowhead-discovered drug candidates that fall outside of our current commercial focus on the cardiometabolic therapeutic area.”

Selected Recent Financial Events
•Strengthened the balance sheet through a strategic financing agreement and licensing and collaboration agreement. We estimate that together, these transactions extend Arrowhead’s cash runway into 2028 and potentially through multiple new drug launches, including wholly owned and partnered programs. These two events were:
◦Signed a licensing and collaboration agreement with Sarepta Therapeutics. Upon closing, Arrowhead will receive $825 million, consisting of $500 million cash and $325 million as an equity investment priced at $27.2507, representing a 35% premium to the 30-day volume weighted average price. Arrowhead also receives $250 million to be paid over five years and is eligible to receive an additional $300 million in near-term payments. Arrowhead is also eligible to receive royalties on commercial sales and approximately $10 billion in potential milestone payments.
◦Closed a strategic financing agreement with Sixth Street for significant, long-term, non-dilutive capital. The $500 million senior secured credit facility includes $400 million funded at close with an additional $100 million available at Arrowhead’s option, subject to mutual agreement between Sixth Street and Arrowhead, during the seven-year term of the agreement.
Selected Recent R&D Events
•Submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for investigational plozasiran for the treatment of familial chylomicronemia syndrome, a severe and rare genetic disease which currently has no FDA approved treatments.
•Received Breakthrough Therapy designation from the FDA for investigational plozasiran as an adjunct to diet to reduce triglycerides in adults with familial chylomicronemia syndrome.


•Announced new results from the Phase 3 PALISADE study and the open-label extension from the Phase 2 MUIR and SHASTA-2 studies of investigational plozasiran. These data were presented in two oral presentations at the American Heart Association Scientific Sessions 2024 (AHA24) and PALISADE data was simultaneously published in the AHA journal, Circulation. Key results include the following:
◦Plozasiran induced deep and sustained reductions in triglycerides and impacted a wide spectrum of lipoproteins that may be involved with atherosclerotic cardiovascular disease
◦Similar responses were observed in patients with genetically confirmed and clinically diagnosed familial chylomicronemia syndrome
◦Mean reductions in triglycerides of up to -73% in patients from MUIR and -86% in patients from SHASTA-2 with favorable reductions in remnant cholesterol and non-HDL-cholesterol were observed through 15 months follow up in the open-label extension
◦Overall, plozasiran has been generally well-tolerated to date. In the PALISADE study, the most frequently reported treatment emergent adverse events for the 25 mg dose were abdominal pain, COVID-19, nasopharyngitis, and nausea. Across clinical studies and study populations, the most frequently reported treatment emergent adverse events for the 25 mg dose were COVID-19, upper respiratory tract infection, headache, Type 2 diabetes mellitus, and abdominal pain.
•Initiated pivotal Phase 3 SHASTA-3 and SHASTA-4 studies of plozasiran in patients with severe hypertriglyceridemia.
•Launched a new disease awareness campaign, ‘We’ll Get There Soon,’ to inspire hope for the rare disease community affected by familial chylomicronemia syndrome.
•Presented data from the Phase 3 PALISADE study of plozasiran in a late-breaking oral presentation at the European Society of Cardiology (ESC) Congress 2024 and simultaneously published in The New England Journal of Medicine.
•Arrowhead’s Verona, WI manufacturing and testing facility successfully completed requirements to manufacture GMP drug substance to support clinical trials conducted in the United States and many other countries abroad, and recently successfully completed a Qualified Person (QP) audit, which allows for internally produced drug substance to be used in support of clinical programs in EU countries and the United Kingdom.
•Filed for regulatory clearance in New Zealand to initiate a Phase 1/2a clinical trial of ARO-INHBE, the company’s investigational RNAi therapeutic being developed as a potential treatment for obesity.
◦In preclinical studies ARO-INHBE reduced body weight and fat mass with a novel mechanism of action that may preserve lean muscle mass compared to currently approved obesity therapies.
•Completed the 2024 Summer Series of R&D webinars, each highlighting a specific therapeutic area in Arrowhead’s pipeline, including the following events:
▪May 23, 2024 – Muscular
▪June 25, 2024 – Cardiometabolic
▪July 16, 2024 – Pulmonary
▪August 14, 2024 – Obesity/Metabolic
▪September 25, 2024 – Central Nervous System

About Plozasiran
Plozasiran, previously called ARO-APOC3, is a first-in-class investigational RNA interference (RNAi) therapeutic designed to reduce production of apolipoprotein C-III (APOC3) which is a component of triglyceride rich lipoproteins (TRLs) and a key regulator of triglyceride metabolism. APOC3 increases triglyceride levels in the blood by inhibiting breakdown of TRLs by lipoprotein lipase and uptake of TRL remnants by hepatic receptors in the liver. The goal of treatment with plozasiran is to reduce the level of APOC3, thereby reducing triglycerides and restoring lipids to more normal levels.
In multiple clinical studies, investigational plozasiran has demonstrated reductions in triglycerides and multiple atherogenic lipoproteins in patients with familial chylomicronemia syndrome (FCS), severe hypertriglyceridemia (SHTG), and mixed hyperlipidemia. Plozasiran has been generally well tolerated to date with treatment emergent adverse events reported that generally reflect the comorbidities and underlying conditions of the study populations. Across clinical studies and study populations, the most frequently reported treatment emergent adverse events for the 25 mg dose were COVID-19, upper respiratory tract infection, headache, Type 2 diabetes mellitus, and abdominal pain.
Plozasiran is being investigated in the SUMMIT program of clinical studies, including the PALISADE Phase 3 study in patients with FCS, the SHASTA studies in patients with SHTG, and the MUIR and CAPITAN studies in patients with mixed hyperlipidemia.
Plozasiran in the treatment of patients with FCS has been granted Breakthrough Therapy Designation, Orphan Drug Designation, and Fast Track Designation by the U.S. Food and Drug Administration and Orphan Drug Designation by the European Medicines Agency. Investigational plozasiran has not been reviewed or approved to treat any disease.
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.
