Arrowhead to Cut Hepatitis B Drug Study Dosage in Mid-Stage Trial  

On January 12, 2015, Arrowhead stock fell over 23% to close at $6.90 per share after the company announced that the U.S. Food and Drug Administration verbally informed the company of a partial clinical hold on its ARC-520 study for patients with chronic hepatitis B. The FDA has informed Arrowhead that it will need to start a new, multi-dose study at one mg/kg instead of the proposed two and four mg/kg. In addition, the FDA has requested additional information from the drug's current mid-stage study.
