Chronic Hepatitis BPhase 4NCT02362490
Efficacy of Peginterferon Alpha 2a Therapy in Chronic Hepatitis B Patients Being Treated With Nucleoside(Acid) Analogues
A Phase 4 study testing peginterferon alpha 2a in people with Chronic Hepatitis B, run by Beijing Ditan Hospital at 1 site in China.
Trial summary
Antiviral therapy is the most important method to slow and stop the progress of the disease in patients with chronic hepatitis B (CHB). Nucleoside (acid) analogues (NA) can Effectively suppress HBV replication, but it should be continue used and relapse would happen in most patients after withdrawal of therapy.

About this study
Official title: HBsAg Clearance of Peginterferon Treatment in Patients Who Had Chronic Hepatitis B and Were on the Treatment of Nucleoside(Acid) Analogues
Antiviral therapy is the most important method to slow and stop the progress of the disease in patients with chronic hepatitis B (CHB). Nucleoside (acid) analogues (NA) can Effectively suppress HBV replication, but it should be continue used and relapse would happen in most patients after withdrawal of therapy. However, long-term use of NA could induce viral resistance mutation lead to loss of efficacy. Interferon treatment can enhance specific and non-specific immune function in chronic hepatitis B patients, make patients get immune control to HBV infection and obtain sustained response after treatment. Thus the CHB patients on the treatment of NA should be stop NA treatment after interferon treatment. In this study, the effects of interferon treatment in CHB patients who were on the NA treatment and obtained HBsAg level≤250 IU/ml.
Read the detailed description
In this trial, patients who were CHB and treated with NA more than 6 months, still on the treatment and achieved HBsAg level ≤250 IU/ml with HBV DNA undetectable will be randomized enrolled into group A (Intervention group), in which patients switch to interferon therapy for 72 weeks, group B(control group), patients continue treated with NA for 72 weeks. Serum HBV DNA load, HBsAg/anti-HBs level, HBeAg/anti-HBe will be tested at enrollment and every 3 months during the treatment course. Parameters of Liver and kidney function, and liver ultrasound examination will be tested with intervals 1-3 months. The efficacies of interferon treatment were devalued by the rate of HBsAg clearance and decline of HBsAg levels on the 72 weeks of interferon treatment compared with control group.

| Study group | Role | What they receive |
|---|---|---|
| peginterferon alpha 2a | Experimental | in this group, patients who were on treatment of Nucleoside (Acid) Analogues and had achieved HBsAg level ≤250 IU/ml will switch to treatment of peginterferon alpha 2a for 72 week. Receives: Drug: peginterferon alpha 2a |
| control group | No intervention | in this group, patients who were on treatment of Nucleoside(Acid) Analogues and had achieved HBsAg level ≤250 IU/ml will be continue to treatment of Nucleoside(Acid) Analogues for 72 week. |
What is being measured
The primary outcome is the main question the study is designed to answer.
rate of HBsAg loss
the effects of peginterferon alpha 2a will be evaluated by HBsAg loss defined as HBsAg level lower than 0.05 IU/ml after 72 week treatment,compared control group.
Measured: 72 weeks
Secondary outcomes (1)
decline of HBsAg level
secondary outcome was evaluated by the decline of HBsAg level after 72 weeks of peginterferon alpha 2a treatment compared with control group.
Measured: 72 weeks

Antiviral therapy is the most important method to slow and stop the progress of the disease in patients with chronic hepatitis B (CHB). Nucleoside (acid) analogues (NA) can Effectively suppress HBV replication, but it should be continue used and relapse would happen in most patients after withdrawal of therapy. However, long-term use of NA could induce viral resistance mutation lead to loss of efficacy. Interferon treatment can enhance specific and non-specific immune function in chronic hepatitis B patients, make patients get immune control to HBV infection and obtain sustained response after treatment. Thus the CHB patients on the treatment of NA should be stop NA treatment after interferon treatment. In this study, the effects of interferon treatment in CHB patients who were on the NA treatment and obtained HBsAg level≤250 IU/ml.

What does the primary outcome measure?
rate of HBsAg loss (time frame: 72 weeks). It is what the study was designed to measure, not a finding.
