E.5 End points |
E.5.1 | Primary end point(s) |
The failure rate after 24 weeks of treatment based on the trough levels of serum anti-HBs ≤ 100 IU/l and the number of hepatitis B related re-infections in patients with trough levels of serum anti-HBs > 100 IU/l. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
End of 24 weeks of treatment, or at a re-occurence of infection. |
|
E.5.2 | Secondary end point(s) |
Efficacy - The number of all patients with hepatitis B related infections will be assessed by monitoring of clinical signs, liver function and measurement of HBsAg and HBV-DNA.
Efficacy - serum anti-HBs concentrations
Safety - Adverse Event profile, heamatology, clinical chemistry and urinalysis
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Adverse Events - each visit
Hepatitis serology - weekly for the first 8 weeks, then monthly until week 24. |
