A Phase IIb Multi-Center, Randomised, Open Label Study to Assess the Efficacy and Safety of Sequential Treatment With GSK3228836 Followed by Pegylated Interferon Alpha 2a in Participants With Chronic Hepatitis B Virus (B-Together)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is intended to evaluate if 12 or 24 weeks of treatment with GSK3228836 followed by up to 24 weeks of pegylated interferon (PegIFN) can increase the rate of hepatitis B virus surface antigen (HBsAg) loss in participants on stable nucleos(t)ide analogue (NA) therapy, and whether virologic response can be sustained once PegIFN treatment is discontinued. Participants will be randomized to receive GSK3228836 for 12 or 24 weeks followed by up to 24 weeks of PegIFN.
