Tolerability, Immunogenicity and Efficacy of HB-110 Administered by Electroporation in Chronic Hepatitis B Patients
An Open-label, Dose-escalating Clinical Study to Evaluate the Tolerability, Immunogenicity and Efficacy of HB-110 Administered by Electroporation (EP) in an Add-on Therapy With Entecavir in Chronic Hepatitis B Patients
Study Overview
Detailed Description
The patients enrolled in the trial will be successively allocated into three cohorts for HB-110 1mg, 2mg, and 4mg in combination with Entecavir according to the classical 3+3 protocol design. They will be administered by Electroporation device.
The scheduled assessments and visits will be carried out over three periods: run-in period, treatment period, and follow-up period.
The run-in period includes the screening visit where a written informed consent is obtained and the screening period where patients are assessed for eligibility. It will be completed within 14 days prior to Visit 1. The patients meeting inclusion criteria will start the treatment period.
During the treatment period, subjects will be administered HB-110 by Electroporation at each visit in combination with antiviral drug, Entecavir.
The Follow-up period starts once subjects complete the treatment period and will continue until the follow-up visit.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: 1mg of HB-110
The subjects in this group will be administered 1 mg of HB-110 according to the protocol.
|
Each patient will be administered HB-110 by Electroporation for 20 weeks based on the protocol and take one pill of Entecavir(0.5 mg) per day during the study period.
The Dose of HB-110 will be determined by the classical 3+3 dose escalation schedule and dose levels are 1mg, 2mg, 4mg respectively.
The number of patients will be ranged from 9 to 18.
