Efficacy & Safety of Tenofovir Disoproxil Fumarate (TDF) Plus Peginterferon α-2a (Peg-IFN) Versus TDF or Peg-IFN Monotherapy in Chronic Hepatitis B

15 июля 2016 г. обновлено: Gilead Sciences

A Phase 4, Randomized, Open-label, Active-Controlled, Superiority Study to Evaluate the Efficacy and Safety of Tenofovir Disoproxil Fumarate (TDF) in Combination With Peginterferon α-2a (Pegasys®) Versus Standard of Care Tenofovir Disoproxil Fumarate Monotherapy or Peginterferon α-2a Monotherapy for 48 Weeks in Non-Cirrhotic Subjects With HBeAg-Positive or HBeAg-Negative Chronic Hepatitis B (CHB)

The primary objective of this study is to evaluate the efficacy of tenofovir disoproxil fumarate (TDF) plus peginterferon α-2a (Peg-IFN) combination therapy for 48 weeks versus standard of care TDF monotherapy or Peg-IFN monotherapy for 48 weeks in non-cirrhotic adults with chronic hepatitis B virus (HBV) as determined by loss of hepatitis B surface antigen (HBsAg).

The study will consist of 2 phases for participants in the TDF+Peg-IFN 48 Weeks, TDF 48 Weeks + Peg-IFN 16 Weeks, and Peg-IFN 48 Weeks groups. Following an initial 48 weeks of treatment, participants in these groups will be monitored for 24 weeks for signs of worsening HBV, and those meeting TDF retreatment and flare management criteria will be eligible to receive TDF monotherapy during a retreatment phase, up to Week 120.

Временное ограничение
Percentage of Participants With HBsAg Loss at Week 72 Following Treatment With 48 Weeks of TDF Plus Peg-IFN Combination Versus Peg-IFN Alone for 48 Weeks or TDF Alone
Временное ограничение: Baseline; Week 72

Loss of HBsAg was defined as change of detectable HBsAg from positive to negative. Proportions are based on a Kaplan-Meier estimate.

The analysis visit window for Week 72 comprised Week 70 through Week 78, so results up to Week 78 are included in this analysis.

Loss of HBeAg was defined as change of detectable HBeAg from positive to negative. HBeAg seroconversion was defined as change of detectable antibody to HBeAg from negative to positive. Percentages were based on the number of subjects with non-missing HBeAg results or missing HBeAg results imputed as failures at each visit.

For the TDF+Peg-IFN 48 Weeks, TDF 48 Weeks + Peg-IFN 16 Weeks, and Peg-IFN 48 Weeks groups, data are presented in the "Not Retreated" column for participants who had not entered the retreatment phase by Week 72, and in the "Retreated" column for participants who did enter the retreatment phase by Week 72.
