About ARC-AAT

Arrowhead’s ARC-AAT is being investigated for the treatment of liver

disease associated with alpha-1 antitrypsin deficiency (AATD), a rare

genetic disease that severely damages the liver and lungs of affected

individuals. The mean estimated prevalence of AATD in the U.S. is 1 per

3000-5000, or approximately 100,000 patients. AATD is also an important

cause of pediatric liver disease with an estimated prevalence in

children of approximately 20,000 patients, and 50-80% likely to manifest

liver disease during childhood. It is a rare disease that is frequently

misdiagnosed or undiagnosed. ARC-AAT employs a novel unlocked nucleobase

analog (UNA) containing RNAi trigger molecule designed for systemic

delivery using the Dynamic Polyconjugate delivery system.

ARC-AAT is highly effective at knocking down the alpha-1 antitrypsin

(AAT) gene transcript and reducing the hepatic production of the mutant

AAT (Z-AAT) protein in animal studies. Reduction of liver production of

the inflammatory Z-AAT protein, which is believed to be the cause of

progressive liver disease in AATD patients, is important as it is

expected to halt the progression of liver disease. ARC-AAT was granted

orphan drug designation in both the United States and in Europe, the

latter being held on Arrowhead’s behalf by a local EU representative

Pharma Gateway AB. Arrowhead is conducting a Phase 1 clinical study of

ARC-AAT, with part A in healthy volunteers (now complete) and part B in

AATD patients, and a Phase 2 multiple dose study in AATD patients.

About ARC-F12

Arrowhead’s RNAi-based candidate ARC-F12 is in preclinical development

as a potential treatment for factor XII (F12) mediated diseases.

Arrowhead sees clear unmet need in hereditary angioedema (HAE) and

thromboembolic diseases. The biology of factor 12 as part of the

coagulation cascade and the kinin-kallikrein system suggest that its

reduction through RNAi may present opportunities in both disease areas.

The company is currently conducting studies in order to advance ARC-F12

into clinical trials.

About ARC-LPA

Arrowhead’s RNAi-based candidate ARC-LPA is in preclinical development

as a potential treatment for cardiovascular diseases. ARC-LPA is

designed to reduce production of apolipoprotein(a), a key component of

lipoprotein(a), or Lp(a). Lp(a) levels in humans are genetically defined

and higher levels correlate with increased risk of cardiovascular

diseases, independent of cholesterol and LDL levels. ARC-LPA is

Arrowhead’s first drug candidate to use a subcutaneously administered

delivery construct.

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. The company’s pipeline includes ARC-520 and ARC-521 for

chronic hepatitis B virus infection, ARC-AAT for liver disease

associated with alpha-1 antitrypsin deficiency, ARC-F12 for hereditary

angioedema and thromboembolic disorders, ARC-LPA for cardiovascular

disease, and ARC-HIF2 for renal cell carcinoma.
