Arrowhead, a biopharmaceutical company, develops novel drugs to treat intractable diseases in the United States. Among the Company’s products under development at all relevant times was ARC-520, an RNAi-based therapeutic in Phase IIb clinical efficacy studies to treat chronic hepatitis B virus infection.

The Complaint alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects.  Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) ARC-520 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) Arrowhead had overstated the approval prospects and commercial viability of ARC-520; and (iv) as a result, Arrowhead’s public statements were materially false and misleading at all relevant times.

On November 8, 2016, post-market, 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.

On this news, Arrowhead’s share price fell $1.91, or 31.26%, to close at $4.20 on November 9, 2016.

On November 29, 2016, post-market, Arrowhead announced that it will “discontinue development of clinical stage drug candidates ARC-520, ARC-521, and ARC-AAT” and cut its workforce by approximately 30%.

On this news, Arrowhead’s share price fell $2.95, or 67.2%, to close at $1.44 on November 30, 2016.
