What is Simeprevir?Simeprevir

Simeprevir (formerly TMC435; trade name Olysio) is a drug for the treatment and cure of hepatitis C. It was developed by Medivir and Johnson & Johnson’s pharmaceutical division Janssen Pharmaceutica. In the United States, simeprevir is approved by the Food and Drug Administration for use in combination with peginterferon-alfa and ribavirin for hepatitis C. Simeprevir has been approved in Japan for the treatment of chronic hepatitis C infection, genotype 1.

Simeprevir is indicated treating chronic hepatic C (CHC) infection as a part of a triple antiviral treatment regimen consisting of two other drugs: peginterferon-alfa (PEG-IFN) and ribavirin (RBV). It is primarily efficacious in treating Hepatitis C virus (HCV) genotype 1 infected subjects with compensated liver disease, including cirrhosis. There are currently no studies that show Simeprevir’s effectiveness as a single therapy for HCV. Simeprevir is generally used for HCV genotype 1 infected subjects, but off-label medical use has been indicated for type 4 genotype as well.

Mechanism of action

Simeprevir is a hepatitis C virus protease inhibitor.

Simeprevir is a NS3/4A protease inhibitor, thus preventing viral maturation through inhibition of protein synthesis. Simeprevir is administered as one capsule once daily with pegylated interferon and ribavirin for the treatment of genotype 1 or genotype 4 chronic hepatitis C in adult patients with compensated liver disease (including cirrhosis), with or without HIV-1 co-infection, who are treatment naive or who have failed previous interferon therapy. Genotype 1 is the most prevalent form of hepatitis C virus (HCV) worldwide.

Adverse effects

Pruritis (22%), photosensitivity (5%), and rash (25%) are some of the common adverse effects of Simeprevir experienced by patients taking it during Phase 3 trials.

Hepatitis C Treatment Combination Dangers

In March 2015, Gilead Sciences e-mailed warnings to health care providers about nine patients that began taking its hepatitis C drugs Harvoni (ledipasvir/sofosbuvir) or Sovaldi (sofosbuvir) along with the heart treatments amiodarone, Bristol-Myers Squibb’s Daklinza (daclatasvir), or Johnson & Johnson’s Olysio (simeprevir) developed abnormally slow heartbeats and one died of cardiac arrest. Three required a pacemaker to be inserted. Gilead said the combinations aren’t recommended and product labels will be updated.
