Hide Detailed Description
Aims & Objectives:
Peg-IFN has five unique features, namely (i) finite duration of administration, (ii) anti-viral effect, (iii) immune-modulation, (iv) anti-fibrotic effect and (v) delayed virologic response off-treatment. However these benefits come at a cost i.e. the drug is expensive and there are several known adverse events.
ETV is a potent nucleoside analogue (Nuc), which has minimal resistance compared to most other Nucs. It is efficient for inducing rapid decline of HBV DNA. However ETV has no known immune modulatory or anti-fibrotic effect and therefore off-treatment response or improvement of hepatic histology is not expected with ETV. Similar to other NUCs, there is no defined duration of administration of ETV.
It has been hypothesized that if lower-dose of Peg-IFN can be given in combination with ETV in treatment-naïve CHB patients, they are likely to benefit most from the 'best of both the drugs' in terms of viral and biochemical responses, treatment cost and duration and adverse events.
The project aims to evaluate the outcome of first-line combination treatment with 'lower-dose Peg-IFN plus ETV' in treatment-naïve CHB patients to see whether this combination may be further evaluated and eventually recommended as first-line management for HBV related chronic liver diseases (CLD).
Although the best treatment option for CHB is not clarified yet, certain therapeutic concepts can be derived from the experience of treating patients with chronic hepatitis C (CHC) and human immunodeficiency virus (HIV) infections. A major advancement in treating CHC and HIV infections has been the development of first-line combination therapy.
The research question of this study is whether the first-line combination treatment with 'lower-dose Peg-IFN plus ETV' is effective and beneficial in treatment-naïve CHB patients and whether this combination may be evaluated further and eventually recommended as the preferred first-line management for HBV related CLD.
Ethical approval for the study has been obtained from the Ethical Committee at Bangabandhu Sheikh Mujib Medical University. The study will be performed according to principle of the 'Declaration of Helsinki' of 1975 maintaining all the requisites and norms of 'good clinical practice' (GCP).
This will be a prospective, open label, interventional clinical study. The first 20 (twenty) treatment-naive hepatitis B virus 'e' antigen (HBeAg) positive CHB patients with treatment indication, presenting from July 2011 onwards, who can afford the treatment with Peg-IFN and who voluntarily agree to be part of the study will be recruited. Signed voluntary consent in Bengali will be obtained from each participant.
Patients will receive peg-IFN (90 µgms) sub-cutaneously once weekly for 24 weeks in combination with ETV (0.5 mg) once daily orally for the same duration. Administration of Peg-IFN will be supervised and patients will be evaluated regularly both clinically and with biochemical and haematological parameters for early detection and management of adverse event(s) if any.
Virologic and biochemical parameters will be tested (i) at baseline, (ii) at end of treatment (i.e. at 24 weeks) and (iii) at 12 weeks off-treatment.
These will include HBeAg, HBV DNA and serum alaninetransaminase (ALT). Besides for assessment of liver status, patients will undergo ultrasonography (USG) of hepato-biliary system (HBS), endoscopy of upper gastrointestinal tract (UGIT) and if possible liver biopsy or fibroscan of liver at baseline.
Data analysis All data will be collected using pre-designed questionnaire and preserved in a safe place. Data will be analysed using SPSS programme.
