The selling stockholders may sell shares to or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders, the purchasers of the shares, or both. If required, the number of shares to be sold, the public offering price of those shares, the names of any underwriters, broker-dealers or agents and any applicable commission or discount will be included in a supplement to this prospectus, called a prospectus supplement.

We recently acquired significant assets from Roche related to RNAi technologies, and Roche retains a right of first negotiation over certain candidates developed based on the acquired RNAi technologies.
On October 21, 2011, we entered into a Stock and Asset Purchase Agreement with Hoffmann-La Roche Inc. and F. Hoffmann-La Roche Ltd, pursuant to which we purchased from Roche (i) all of the outstanding common
2
stock of Roche Madison Inc. and (ii) the intellectual property rights currently held by Roche related to its RNAi business and identified in the RNAi Purchase Agreement. Pursuant to the RNAi purchase agreement, Roche has a limited right of first negotiation on certain product candidates developed by us relating to the purchased assets. This right of first negotiation applies to all three Existing Candidates (disease targets previously studied by Roche) and to up to five other drug candidates that we may develop. The right of first negotiation could delay the process of entering into a strategic relationship related to any product candidates developed based on the acquired RNAi technologies and could adversely impact our ability to attract a partner or acquirer for any such product candidates and could negatively impact the prospects for a larger company to acquire Arrowhead.
The proceeds from the resale of the Shares under this prospectus are solely for the account of the Selling Stockholders. We will not receive any proceeds from the sale of Shares under this prospectus.
The Company has included in this prospectus 1,597,072 shares of Common Stock issued upon the closing of the Private Placement.
In connection with the Private Placement, we have agreed to file a registration statement with the Securities and Exchange Commission covering the resale of the Private Placement Shares.
The following table sets forth certain information regarding the Selling Stockholders and the shares of Common Stock beneficially owned by them, which is based on information that is available to us as of January 6, 2012. Selling Stockholders may offer shares under this prospectus from time to time and may elect to sell none, some or all of the shares set forth next to their name. As a result, we cannot estimate the number of shares of Common Stock that a Selling Stockholder will beneficially own after termination of sales under this prospectus. In addition, a Selling Stockholder may have sold, transferred or otherwise disposed of all or a portion of that holder’s shares of Common Stock since the date on which they provided information for this table. We have not made independent inquiries about this.
Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Shares of our common stock subject to options or warrants that are currently exercisable or exercisable within 60 days of January 6, 2012 are considered outstanding and beneficially owned by the person holding the options or warrants for the purpose of calculating the percentage ownership of that person but not for the purpose of calculating the percentage ownership of any other person.
The Company implemented a 1 for 10 reverse split of its common stock on November 17, 2011. All share amounts have been adjusted to reflect post-split amounts and percentages of beneficial ownership are based on 10,525,941 common shares issued and outstanding as of January 6,
3
2012. Shares not outstanding but deemed beneficially owned by virtue of the right of a person to acquire them as of January 6, 2012, or within sixty days of such date, are treated as outstanding only when determining the percentage owned by such individual and when determining the percentage owned by a group of which such individual is a member.
We are relying on written commitments from the Selling Stockholders to notify us of any changes in their beneficial ownership after the date they originally provided this information. See “Plan of Distribution” beginning on page 5.

The Shares offered by this prospectus may be sold by the Selling Stockholders. Such sales may be made at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, or at negotiated prices, and may be made in the over-the-counter market or any exchange on which our common stock may then be listed, or otherwise. In addition, the Selling Stockholders may sell some or all of their Shares through:
| • | a block trade in which a broker-dealer may resell a portion of the block, as principal, in order to facilitate the transaction; |
| • | purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account; |
| • | ordinary brokerage transactions and transactions in which a broker solicits purchasers; |
| • | in negotiated transactions; |
| • | in a combination of any of the above methods of sale; or |
| • | any other method permitted under applicable law. |
The Selling Stockholders may also engage in short sales against the box, puts and calls and other hedging transactions in the Shares or derivatives of the Shares and may sell or deliver the Shares in connection with these trades. For example, the Selling Stockholders may:
| • | enter into transactions involving short sales of our common stock by broker-dealers; |
| • | sell our common stock short themselves and redeliver such shares to close out their short positions; |
| • | enter into option or other types of transactions that require the Selling Stockholder to deliver shares of common stock to a broker-dealer, who will then resell or transfer the common stock under this prospectus; or |
| • | loan or pledge shares of common stock to a broker-dealer, who may sell the loaned shares or, in the event of default, sell the pledged shares. |
| • | There is no assurance that any of the Selling Stockholders will sell any or all of the Shares offered by them. |
The Selling Stockholders may negotiate and pay broker-dealers commissions, discounts or concessions for their services. Broker-dealers engaged by the Selling Stockholders may allow other broker-dealers to participate in resales. However, the Selling Stockholders and any broker-dealers involved in the sale or resale of our common stock may qualify as “underwriters” within the meaning of the Section 2(a)(11) of the Securities Act. In addition, the broker-dealers’ commissions, discounts or concessions may qualify as underwriters’ compensation under the Securities Act. If the Selling Stockholders qualify as “underwriters,” they will be subject to the prospectus delivery requirements of the Securities Act.
In addition to selling their shares of common stock under this prospectus, the Selling Stockholders may:
| • | transfer their common stock in other ways not involving market makers or established trading markets, including, but not limited to, directly by gift, distribution, privately negotiated transactions in compliance with applicable law or other transfer; or |
| • | sell their common stock under Rule 144 of the Securities Act rather than under this prospectus, if the transaction meets the requirements of Rule 144. Each Selling Stockholder will bear all expenses with respect to the offering of common stock by such Selling Stockholder. |
Under the applicable rules and regulations of the Exchange Act, any person engaged in the distribution of the Shares may not simultaneously engage in market making activities with respect to our common stock for a period of
5
two business days prior to the commencement of such distribution. In addition, each Selling Stockholder will be subject to the applicable provisions of the Exchange Act and the associated rules and regulations under the Exchange Act, including Regulation M, which provisions may limit the timing of purchases and sales of shares of our common stock by the Selling Stockholders.
The Selling Stockholders may from time to time pledge or grant a security interest in some or all of the Shares owned by them and, if they default in the performance of their secured obligations, the pledges or secured parties may offer and sell the Shares from time to time under this prospectus after an amendment has been filed under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of Selling Stockholders to include the pledge, transferee or other successors in interest as selling stockholders under this prospectus.
The Selling Stockholders also may transfer the Shares in other circumstances, in which case the respective pledgees, donees, transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and may sell the Shares from time to time under this prospectus after an amendment has been filed under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of Selling Stockholders to include the pledge, transferee or other successors in interest as selling stockholders under this prospectus.
We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver copies of this prospectus to purchasers at or prior to the time of any sale of the Shares.
We will bear all costs, expenses and fees in connection with the registration of the Shares. The Selling Stockholders will bear all commissions and discounts, if any, attributable to the resale of the Shares. The Selling Stockholders may agree to indemnify any broker-dealer or agent that participates in transactions involving sales of the Shares against certain liabilities, including liabilities arising under the Securities Act.
