Is Daclastavir a substrate?
Daclastavir is a substrate of CYP3A enzymes where its metabolism is predominantly mediated by CYP3A4 isoform. Oxidative pathways included δ-oxidation of the pyrrolidine moiety, resulting in ring opening to an aminoaldehyde intermediate followed by an intramolecular reaction between the aldehyde and the proximal imidazole nitrogen atom. High proportion of the drug in the plasma (greater than 97%) is in the unchanged form.
Does Daclatasvir cause enzyme elevation?
In large randomized controlled trials, daclatasvir was not associated with serum enzyme elevations during therapy. A difficulty in assessing side effects of daclatasvir and other anti-HCV agents, however, is that they are never used as monotherapy, but are also combined with agents active against other HCV targets, such as the viral protease (NS3) or polymerase (NS5B). Daclatasvir is also commonly used in combination with the more traditional agents used for hepatitis C, such as peginterferon and ribavirin, both of which have prominent adverse effects. In combination with asunaprevir (an HCV protease inhibitor), daclatasvir was associated with serum ALT elevations in 3% to 11% of patients and with several instances of acute hypersensitivity and hepatitis, some of which were severe. The cause of the hypersensitivity reaction, however, appeared to be asunaprevir. In combination with sofosbuvir, daclatasvir has not been associated with serum enzyme elevations or with clinically apparent liver injury.

What is the role of Daclatasvir in hepatitis C?
Daclatasvir was discovered as a first-in-class inhibitor of the non-structural viral protein 5A (NS5A), a phosphoprotein that plays an important role in hepatitis C replication. The exact mechanism by which daclatasvir inhibits the NS5A replication complex is unclear, but it is believed that daclatasvir inhibits viral RNA replication and virion assembly. It may also inhibit phosphorylation of the NS4A, and therefore the formation and activation of the HCV replication complex. Based on in vitro data, daclatasvir has shown activity against HCV genotypes 1 through 6, with EC50 values ranging from picomolar to low nanomolar against wild type HCV.

Is Daclatasvir a genotype?
Daclatasvir plus sofosbuvir, with or without ribavirin, is an all-oral option for the treatment of genotype 1 or 3 chronic HCV across a variety of patient populations. Based on the results of the phase 3 ALLY trials, daclatasvir and sofosbuvir is an effective, albeit very expensive option for patients with genotype 1 or 3 HCV, including those with cirrhosis, HIV coinfection, or post-liver transplantation. The use of daclatasvir with sofosbuvir has provided an important ribavirin-free oral option for genotype 3 patients, but the 12 week dual therapy has limited efficacy in cirrhotic genotype 3 patients. Cost, lack of coformulation, and the recommendation of baseline NS5A testing in genotype 1a cirrhotic patients make daclatasvir plus sofosbuvir a less compelling option in this subset of patients.
