Chronic Hepatitis C Genotype 1 Previously Treated with an NS5A Inhibitor Regimen

Chronic hepatitis C genotype 1 is a serious liver infection caused by the hepatitis C virus (HCV). It can lead to cirrhosis, liver cancer, and other life-threatening problems. The majority of people with hepatitis C genotype 1 (nearly 80%) will require treatment to help prevent these serious complications.

The standard of care for patients with chronic hepatitis C genotype 1 includes treatment with direct-acting antiviral (DAA) medications. A DAA regimen incorporating an NS5A inhibitor can be used to treat the virus. NS5A inhibitors are antiviral drugs that target a specific protein (called NS5A) that is essential for the virus to survive and replicate.

There is a variety of NS5A inhibitors available, including ledipasvir, ombitasvir, elbasvir, grazoprevir, pibrentasvir, sofosbuvir, and velpatasvir. These drugs are effective when used in combination with other DAAs to treat hepatitis C genotype 1. Studies have found that a DAA-based regimen containing an NS5A inhibitor can result in sustained virological response (SVR) rates of 95-100%. SVR is defined as the absence of detectable virus in the blood 24 weeks after the completion of treatment.

Patients with chronic hepatitis C genotype 1 who are being treated with an NS5A inhibitor-containing DAA regimen should be closely monitored for signs and symptoms of drug-related adverse events. Possible side effects of these drugs can include fatigue, headache, nausea, abdominal pain, and rash. If symptoms are severe or persist, it is important to seek medical advice from a healthcare provider.
