Selected Fiscal 2018 Second Quarter and Recent Events

Strengthened the balance sheet with an equity financing yielding gross proceeds of $60.4 million

Received orphan drug designation from the United States Food and Drug Administration (FDA) for ARO-AAT, Arrowhead’s second-generation investigational medicine for the treatment of a rare genetic liver disease associated with alpha-1 antitrypsin deficiency

Initiated dosing in AROAAT1001 (NCT03362242), a Phase 1 single- and multiple-ascending dose study to evaluate the safety, tolerability, pharmacokinetics, and effect of ARO-AAT on serum alpha-1 antitrypsin levels in healthy adult volunteers

Initiated dosing in AROHBV1001 (NCT03365947), a Phase 1/2 study to evaluate the safety, tolerability, and pharmacokinetic effects of single-ascending doses (SAD) of ARO-HBV in healthy adult volunteers, and to evaluate the safety, tolerability, and pharmacodynamic effects of multiple-ascending doses (MAD) of ARO-HBV in patients with chronic HBV

Presented clinical data on ARC-520, the company’s prior generation investigational medicine for the treatment of chronic hepatitis B infection, at The International Liver Congress 2018 (ILC), the annual meeting of the European Association for the Study of the Liver (EASL), including the following key results:

Multiple doses of ARC-520 resulted in s-antigen reductions in all patients by as much as 5.3 Log10

Where measurable, multi-log reductions were also seen in e-antigen, core-related antigen, DNA and HBV RNA

One e-antigen negative patient, while remaining on entecavir, serocleared for all measurable viral markers including s-antigen, core-related antigen, HBV RNA, and HBV DNA. We believe this will represent a functional cure

2 out of 3 e-antigen positive and 2 out of 5 e-antigen negative patients, or half of the patients in the study, achieved productive and sustained host responses. These were characterized by mild ALT elevations coinciding with continued reductions in various viral markers which persisted after ARC-520 therapy was removed

Two patients that experienced sustained host responses but had not yet serocleared, appear poised to potentially seroclear if the trends in the decrease of viral markers continues

Presented preclinical data on both ARO-AAT and ARO-HBV at EASL

Made continued progress on the emerging pipeline of RNAi therapeutics developed using the Targeted RNAi Molecule (TRiMTM) platform including:

The cardiometabolic pipeline, which includes ARO-APOC3, targeting apolipoprotein C-III (ApoC3), and ARO-ANG3, targeting angiopoietin-like protein 3 (ANGPTL3)

The pulmonary pipeline, which includes ARO-ENaC, formerly called ARO-Lung1, which is an inhaled RNAi therapeutic targeting the epithelial sodium channel alpha subunit (aENaC) for the treatment of cystic fibrosis

ARO-HIF2 for the treatment of clear cell renal cell carcinoma
