Summary
The first direct-acting antiviral, telaprevir, is now approved for hepatitis C virus (HCV) treatment. Future therapies may combine novel antivirals without interferon for improved standard of care.
Area of Science:
- Hepatology and Virology
- Drug Development
Context:
- Hepatitis C virus (HCV) infection remains a significant global health concern.
- The recent approval of telaprevir, a first-generation direct-acting antiviral (DAA), marks a significant advancement in HCV treatment.
- Telaprevir targets the HCV NS3/4A serine protease and is used in combination therapy.
Purpose:
- To review the current landscape of hepatitis C virus (HCV) treatment.
- To highlight the emergence of direct-acting antivirals (DAAs) and their impact.
- To discuss the future directions in HCV drug development.
Summary:
- The first-generation protease inhibitor, telaprevir, has been approved in Japan for treating genotype 1 high viral load hepatitis C when combined with pegylated-interferon and ribavirin.
- Over 50 new antivirals targeting various HCV components (NS3/4A protease, NS5B polymerase, NS5A) are in development.
- Future standard of care is expected to involve interferon-free combination therapies using different classes of DAAs.
Impact:
- Telaprevir represents a breakthrough in HCV therapy, offering a new standard of care for specific patient groups.
- The pipeline of novel antivirals promises more effective and potentially curative treatments for hepatitis C.
- Interferon-free regimens are anticipated to improve patient outcomes and treatment accessibility.

01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:30Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
01:10Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
01:29Subviral Agents
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
02:33Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
