Dose Ranging Study of Pegylated Interferon Lambda in Patients With Hepatitis B and Positive for the Hepatitis B e Antigen

Summary

At least 1 dose of pegIFNλ will be identified which is safe, well tolerated, and efficacious for the treatment of chronic hepatitis B virus infection (CHB) Amendment 7, Part B Sub Study: The primary purpose of this amendment is to obtain preliminary data on the safety of pegylated interferon Lambda (Lambda) when administered in combination with Entecavir(ETV) to patients with hepatitis E antigen-positive (HBeAg-positive) chronic hepatitis B(CHB) infection employing a sequential therapy approach
