Worldwide, approximately 325 million people are chronically infected with hepatitis B (HBV) or C (HCV) viruses and 15 million people have hepatitis D and B co-infections. These infections often have an insidious course of disease that targets the liver cells leading to liver cirrhosis or liver cancer. A preventive vaccine against HBV exists. However, once the disease is present, antiviral drugs can only curb viral replication but not stop it. Co-infections with HDV present an additional complication as they are responsible for a particularly rapid development of liver cirrhosis. Over the past few years, patients suffering from hepatitis C infections have been cured with novel virostatic agents (direct acting antivirals, DAA) that demonstrate high success rates and few side effects. However, no vaccine against the virus exists. An ongoing major challenge in hepatitis management is the individualised treatment of patients that are difficult to treat—also with regard to cost optimisation.
DZIF scientists aim to improve prevention and treatment of viral hepatitis, the ultimate goal being to find a cure.
- Epidemiology of viral hepatitis in low-income countries
A large epidemiological study on chronic HBV infection is being conducted in Burkina Faso. Based on this study data, specific measures against viral hepatitis could also be implemented in other low-income countries.
- Identifying new target sites and developing new therapies
Two joint projects are conducting research on cures for hepatitis B and D infections. Amongst others, the specific entry inhibitor myrcludex B is being developed and is already undergoing clinical testing.
- Optimising hepatitis C treatment
Scientists research the role of resistance to antiviral drugs as well as treatment strategies for particularly difficult-to-treat patients—for instance, for patients who have already developed advanced cirrhosis.
- Hepatitis C prevention
Development of vaccines against hepatitis C based on data on the body’s immune response in patients who had a spontaneous cure of hepatitis C infection.
- Developing a network for clinical trials
As a DZIF-wide platform, the infrastructure HepNet Study House provides support with establishing patient cohorts and conducting clinical trials on hepatitis. It enables closely meshed networking within the DZIF as well as in Germany and Europe.
