Introduction
The fixed-dose combination of glecaprevir / pibrentasvir (trade name: Maviret) has been approved in Germany since July 2017 for the treatment of chronic hepatitis C in adults. Since April 2019, it has also been approved for teenagers from the age of 12.
Hepatitis C viruses (HCV) attack the liver, where they can cause acute inflammation. There are seven known forms of hepatitis C viruses, referred to as genotypes 1 to 7. In up to 80 out of 100 people with hepatitis C, the immune system is unable to successfully fight the virus on its own. These people develop a permanent (chronic) inflammation of the liver which can cause cirrhosis. The liver then starts working less effectively. As long as the effect on liver performance isn't noticeable, it is known as “compensated cirrhosis." Signs of advanced (decompensated) cirrhosis include fluid retention in the abdominal cavity, blood clotting problems, and neurological and psychiatric problems, sometimes even as severe as a coma. The risk of liver cancer increases too.
It is currently believed that a treatment can reduce the risk of such complications if patients consistently have no detectable virus in their blood following that treatment. The combination of glecaprevir / pibrentasvir is used to try to keep the viruses from multiplying.
