Sofosbuvir has a number of ideal properties, including pan-genotypic activity, once daily dosing, no meal restrictions, few adverse effects, minimal drug-drug interactions, high genetic barrier to resistance, good safety and efficacy in patients with advanced liver disease, and excellent sustained virologic response rates in patients with unfavorable baseline characteristics; due to all these properties it is of special interest among the directly acting antiviral drugs under development.

History

In 2007; Michael Sofia, a scientist at Pharmasset, a pharmaceutical exporter for hospitals discovered Sofosbuvir.

In 2010:  It was first tested in people.

In December 2013:  Sofosbuvir was approved by the FDA for treatment of HCV genotypes.

In January 2014:  it obtained marketing authorization from the European Commission (EC) as a single agent once-daily oral drug for the treatment of CHC genotypes.

Medical use

Sofosbuvir was recommended as first-line therapy in combination with other antivirals for all six genotypes of Hepatitis C by the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) in 2016. Generally, it is indicated for

Depending on the genotype, sofosbuvir is often used in combination with other antivirals to cure, or achieve a sustained virologic response ; antivirals that are used in these combinations include Ledipasvir, Velpatasvir, Daclatasvir, Simeprevir, Elbasvir, Grazoprevir, Ribavirin, Peginterferon alfa-2a, or Peginterferon alfa-2b with the intent, after 12 weeks of daily therapy.

Mechanism

With the development of Direct-Acting Antivirals (DAAs) such as sofosbuvir, treatment options for chronic Hepatitis C have advanced significantly since 2011. sofosbuvir molecule prevents Hepatitis C virus (HCV) to replicate itself. The RNA molecule of the virus is one of the necessary components for replication. A virus uses an enzyme called RNA polymerase to replicate RNA in order to make a copy of RNA for the new virus formation.
Sofosbuvir inhibits enzyme RNA polymerase – the cellular worker that performs the replication process. The existing Hepatitis C viruses could not make new viruses due to sofosbuvir mechanism of action.

Market

Among all the types of hepatitis, Hepatitis C is the most dangerous one. Around 150 million people are infected with hepatitis C around the world and 350,000 people die every year. It is estimated that about 215,000 people in the UK chronically be infected with hepatitis C.
