Summary
Daclatasvir combined with sofosbuvir effectively treats hepatitis C virus (HCV) genotype 3. High sustained virological response (SVR) rates are seen in patients without cirrhosis, but lower rates occur in those with cirrhosis.
Area of Science:
- Hepatology
- Virology
- Pharmacology
Background:
- Chronic hepatitis C virus (HCV) infection poses a significant global health burden.
- Effective antiviral therapies are crucial for managing HCV, particularly specific genotypes.
Purpose of the Study:
- To review the pharmacology, efficacy, and safety of daclatasvir for treating chronic hepatitis C virus (HCV) infection.
- To assess daclatasvir's role in combination therapy for HCV genotype 3.
Main Methods:
- Literature search of EMBASE and PubMed (1966-2015) using "BMS-790052", "daclatasvir", and "hepatitis C".
- Inclusion of Phase 1, 2, and 3 human studies published in English.
- Review of new drug applications and prescribing information.
Main Results:
- Daclatasvir, a NS5A inhibitor, combined with sofosbuvir is indicated for HCV genotype 3.
- The ALLY-3 trial showed 12-week daclatasvir/sofosbuvir achieved high sustained virological response (SVR) rates (>94%) in non-cirrhotic patients.
- Lower SVR rates (58-69%) were observed in cirrhotic patients; common adverse events included headache, fatigue, and nausea.
Conclusions:
- Daclatasvir plus sofosbuvir is effective for HCV genotype 3, achieving >90% SVR in non-cirrhotic patients.
- Efficacy is reduced in patients with cirrhosis, highlighting the need for tailored treatment strategies.
- The combination demonstrates a favorable safety profile with manageable adverse events.

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.

01:30Inhibitors of Viral Protein Synthesis
26
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...

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

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
15.9K
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’...

1.3K
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...
