Brief Summary

Hepatitis C is an important health problem in Myanmar affecting around 3% of the population. New drugs have been developed which have transformed the treatment of this disease around the world with very high success rates. Two of these drugs are now registered for use in Myanmar. In this study 200 patients with chronic hepatitis C(100 with HIV co-infection) will be assessed and started on the new treatment. We will observe them and measure treatment effectiveness and tolerability. In 24 patients extra blood samples will be taken for drug measurements to describe the effect of the drugs on patients in Myanmar in more detail.

Detailed Description

Data concerning Hepatitis C virus (HCV) prevalence in Myanmar is scarce. Preliminary results of a survey, conducted in 2015 in different areas in Myanmar estimated a seroprevalence of HCV of around 2.65 %, which represents 1.3 million infected patients. Genotype 6 was mostly found in the northern cities and genotype 3 in the southern and western cities of Myanmar. However, treatment options for HCV in Myanmar remain limited currently, including for patients with HIV co-infection who are generally considered high priority given their increased risk for liver disease.

New direct acting antiviral therapies which can achieve high rates of sustained virological response (SVR) (>90%), defined as complete suppression of the virus 12 weeks after completion of antiviral therapy, are becoming increasingly available worldwide.

In Myanmar, in mid-2015, the guideline for the treatment of chronic hepatitis C infection of the Myanmar GI and Liver Society was revised in line with the recent development of Directly Acting Antiviral (DAA) drugs. This observational study will follow the recommendations for patient care presented in this guideline. Two hundred patients with chronic hepatitis C (100 with HIV co-infection) will be recruited in this observational study of routine care with two newly available antiviral drugs (sofosbuvir+ daclatasvir) in two different groups of patients (with and without HIV coinfection) at two centres in Yangon, Myanmar. Their response to treatment will be monitored. In addition a pharmacokinetic study is planned in a subset of patients to characterise any determinants of treatment response or tolerability in patients in Myanmar. This study will be conducted in compliance with the protocol, GCP and the applicable regulatory requirements
