Phase I Study of INO-1800 With or Without INO-9112 + EP in Chronic Hepatitis B Subjects

Phase 1
Completed
Conditions
Hepatitis B
Interventions
Biological: INO-1800
Drug: Nucleos(t)ide Analogue Treatment
Biological: INO-9112
Registration Number
NCT02431312

Brief Summary

This was an open-label study that evaluated the safety, tolerability, and immunogenicity of dose combinations of INO-1800 (DNA plasmids encoding Hepatitis B surface antigen \[HBsAg\] and Hepatitis B core antigen \[HBcAg\]) and INO-9112 (DNA plasmid encoding human interleukin 12) delivered by electroporation (EP) in 90 (ninety) nucleos(t)ide analogue treated participants.

Primary Outcome Measures
NameTimeMethod
Safety Assessment (Composite of multiple measures: pain (VAS), adverse events, lab abnormalities, changes in vital signs)Signing of ICF through up to 76 weeks following the first dose

Composite outcome measure consisting of multiple measures, including:

1. Local pain immediately after Study Treatment/EP and at select times using a visual analog scale (VAS) from 0 to 10, with 0 representing "No Pain" and 10 representing "Worst Pain"

2. Frequency and severity of local and systemic events for at least 7 days after Study Treatment/EP

3. Frequency and severity of laboratory abnormalities

4. Frequency and severity of all adverse events

5. Changes in vital signs

Secondary Outcome Measures
NameTimeMethod
Viral/Antiviral AssessmentScreening and/or first dose and select points up to 76 weeks after the first dose

Composite outcome measure consisting of multiple measures, including:

1. Evaluate effect on HBsAg kinetics as measured in the quantitative HBsAg assay

2. Evaluate effect on maintenance of HBV DNA suppression (\< 90 IU/ml) as measured in the quantitative viral load assay

Immunogenicity AssessmentBaseline (screening and first dose) and select points up to 76 weeks after the first dose

Composite outcome measure consisting of multiple measures, including

1. Breadth and Magnitude of antigen specific cellular immune responses

* Interferon-ɣ ELISpot

* Flow Cytometry for T-cell activation, cytolytic phenotype, memory phenotype

2. Breadth and Magnitude of antigen specific ELISA
