Combination Treatment of NAs and Peg IFN α-2b for Hepatitis B Related, Compensatory Cirrhosis Patients

Combination Treatment of NAs and Peg IFN α-2b for Hepatitis B Related, Compensatory Cirrhosis Patients

Combination Treatment of Nucleoside （Acid）Analogue (NAs) and Pegylated Interferon α-2b for NAs Treated, Hepatitis B Related, Compensatory Cirrhosis Patients With Low Level Hepatitis b Virus Surface Antigen (HBsAg)

The study aims to demonstrate that whether treatment of nucleoside （acid）analogues (NAs) plus pegylated interferon (Peg IFN) α-2b for those NAs treated, low level of HBsAg, hepatitis B related compensatory cirrhosis patients will result in higher HBsAg clearance rate and reduce the risk of liver cancer. The investigators plan to enroll about 84 hepatitis B related compensatory cirrhosis patients, who have received NAs treatment more than 1 year with the level of HBsAg <1000IU/ml. These participants will be devided into 2 groups. Group A will receive the treatment of NAs plus Peg IFNα-2b. Group B will be treated with NAs as before enrollment. The participants in both groups will be followed up for 96 weeks. The primary endpoint is to compare the clearance rate of HBsAg between two groups. The secondary endpoint includes: (1) comparing the incidence of liver cancer during the 96 weeks follow-up, (2) comparing adverse side effects between the 2 groups. (3) comparing the virological and biochemical responses between the 2 groups.

Clearance of hepatitis B virus surface antigen (HBsAg) is considered to be the ultimate therapeutic goal for hepatitis B patients, for it is related with low incidence of fibrosis and liver cancer. The investigators' previous study show that nucleoside （acid）analogues (NAs) treated, non-cirrhosis hepatitis B patients switched to /or combined with pegylated interferon (Peg IFN)α-2b could obtain a higher HBsAg clearance rate. Hence, the investigators' hypothesis is that treatment of NAs plus Peg IFNα-2b for those NAs treated, low level of HBsAg, hepatitis B related compensatory cirrhosis patients result in higher HBsAg clearance rate and reduce the risk of liver cancer. The investigators plan to enroll about 84 hepatitis B related compensatory cirrhosis patients, who have received NAs treatment more than 1 year with the level of HBsAg <1000IU/ml. These participants will be devided into 2 groups according to their wishes. Group A will receive the treatment of NAs (patients previously treated with telbivudine will be changed to entecavir) plus Peg IFNα-2b （180ug per week, the dose will be changed to 135ug or 90ug per week during the treatment if patients could not tolerate the side effects of Peg IFNα-2b）. Peg IFNα-2b treatment will be performed until HBsAg <0.05IU/ml, with a maximum duration of 48 weeks. Group B will be treated with NAs as before enrollment. The participants in both groups will be followed up for 96 weeks. The primary endpoint is to compare the clearance rate of HBsAg between two groups. The secondary endpoint includes: (1) comparing the incidence of liver cancer during the 96 weeks follow-up, (2) comparing adverse side effects, such as ascites, gastrointestinal bleeding, encephalopathy, hepatorenal syndrome between the 2 groups. (3) comparing the virological and biochemical responses between the 2 groups.

NAs+Peg IFN Group will receive the treatment of NAs (patients previously treated with telbivudine will be changed to entecavir) plus pegylated interferon (Peg IFN)α-2b.

Participants in NAs+Peg IFN Group will be treated by Peg IFNα-2b （180ug per week, the dose will be changed to 135ug or 90ug per week during the treatment if patients could not tolerate the side effects of Peg IFNα-2b). Peg IFNα-2b treatment will be performed until HBsAg <0.05IU/ml, with a maximum duration of 48 weeks.

Adverse side effects, such as ascites, gastrointestinal bleeding, encephalopathy, hepatorenal syndrome will be compared between 2 groups

The levels of alanine transaminase, glutamic-oxalacetic transaminase, albumin, total bilirubin, INR will be compared between the 2 groups.
