Peg-interferon ADDed to an Ongoing Nucleos(t)Ide Based Treatment in Patients With Chronic Hepatitis B to Induce Decrease of HBs-Antigen (PADD-ON)

February 5, 2020 updated by: Peter R. Galle, Johannes Gutenberg University Mainz

A Prospective, Randomised, Open-label Phase IIb Clinical Trial Assessing the Effect of Pegylated Interferon Alfa-2a (Pegasys®)180 μg Once Weekly for 48 Weeks in Addition to an Ongoing Nucelos(t)Ide Based Treatment on Quantitative HBsAg Levels in Patients With Chronic HBeAg-negative Hepatitis B

A prospective, randomised, open-label phase IIb clinical trial assessing the effect of pegylated interferon alfa-2a(Pegasys®) 180 μg once weekly for 48 weeks added to an ongoing nucleos(t)ide based treatment in patients with chronic HBeAg-negative hepatitis B

The primary objective of the trial is to investigate whether the add-on of pegylated interferon alfa-2a to a continued treatment with nucleos(t)ide analogues increases the percentage of patients who have significant decrease (≥ 1log10) of HBs antigen after 48 weeks.

170 Patients with chronic hepatitis B, HBe antigen negative, already being treated with an oral antiviral regimen and having a nondetectable viral load for at least 12 months are included.

Measure Description
Time Frame
Difference in Percentage of Patients Between Treatment and Comparator Arm Reaching a ≥ 1log10 Decline of Quantitative HBsAg After 48 Weeks
Time Frame: 48 weeks

Outcome Measure
Measure Description
Time Frame
Change in Quantitative HBs Antigen at Week 12
Time Frame: week 12
Change in quantitative HBs antigen at week 12. The data were log transformed before analysis and the changes to baseline were analysed. Therefore, the reported values might be interpreted as percentage changes. Lower scores mean a better outcome.

Change in Quantitative HBs Antigen at Week 24
Time Frame: week 24
Change in quantitative HBs antigen at week 24. The data were log transformed before analysis and the changes to baseline were analysed. Therefore, the reported values might be interpreted as percentage changes. Lower scores mean a better outcome.
