Arrowhead Pharmaceuticals, Inc. (ARWR)



Faruqi & Faruqi, LLP Encourages Investors Who Suffered Losses In Excess Of $100,000 Investing In Arrowhead Pharmaceuticals, Inc. To Contact The Firm Before Lead Plaintiff Deadline

Faruqi & Faruqi, LLP, a leading national securities law firm, reminds investors in Arrowhead Pharmaceuticals, Inc. (“Arrowhead” or the “Company”) (NASDAQ:ARWR) of the January 17, 2017 deadline to seek the role of lead plaintiff in a federal securities class action lawsuit filed against the Company and certain officers.

The lawsuit has been filed in the U.S. District Court for the Central District of California on behalf of all those who purchased Arrowhead common stock between May 11, 2015 and November 8, 2016 (the “Class Period”).  The case, Meller v. Arrowhead Pharmaceuticals, Inc. et al, No. 2:16-cv-08505 was filed on November 15, 2016.

The lawsuit focuses on whether the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (i) ARC-520, an RNAi-based therapeutic to treat chronic hepatitis B virus infection, was fatal at certain doses; (ii) consequently, the U.S. Food & Drug Administration (“FDA”) was unlikely to approve ARC-520 as a hepatitis B treatment; (iii) the Company overstated the approval prospects and commercial viability of ARC-520; and (iv) as a result, Arrowhead’s public statements were materially false and misleading.

Specifically, during after-market hours on November 8, 2016, Arrowhead issued a press release announcing that the FDA would be placing a clinical hold on the Company’s Heparc- 2004 clinical study of ARC-520, likely due to deaths at the highest dose of an ongoing non-human primate toxicology study.

After this announcement, Arrowhead’s share price fell from $6.11 per share on November 8, 2016 to a closing price of $4.20 on November 9, 2016—a $1.91 or a 31.26% drop.
