Arrowhead Is Accused of Misrepresenting Its ARC-520 Drug
According to the complaint, shares of Arrowhead fell $5.48 per share, or nearly 44%, to close at $7.03 per share on October 8, 2014, following the company's announcement that its Phase IIa study of ARC-520, an RNAi therapeutic that targets the hepatitis B virus, only reduced hepatitis B surface agents by 0.3 log reduction in humans. Further, TheStreet.com published an article the same day, noting that Arrowhead had known for months that ARC-520 yielded 0.2 log and 0.3 log reductions based on a 1 mg/kg and 2 mg/kg doses, respectively, in humans despite previously suggesting that ARC-520 was slated to reduce hepatitis B surface antigens by a 0.8 log reduction, similar to the reduction reached by chimpanzees in the Phase I study.
