Cell experiment: |
HCV genotype 1a and 1b replicon cells are maintained in media containing Daclatasvir at a concentration of 5- to 20-fold above EC50 and 0.5 mg/mL G418. Replicon cells similarly treated with DMSO are maintained as controls. After approximately 4-5 weeks when cell growth is similar to DMSO-treated control cells, selected cells are expanded for resistance testing and analysis by PCR with reverse transcription[1]. |
|
Animal experiment: |
Mice[2] Humanized liver chimeric mice, whose chimeric rate of the liver is estimated as over 40 %, are injected intravenously with 100 µL of HCV-positive human serum samples. After inoculation, their blood is collected from an external jugular vein every 1-4 weeks. The HCV RNA levels are measured by the COBAS TaqMan HCV test in 100-fold diluted serum with a lower measurement range of 3.2 log IU/mL serum. After serum levels of HCV RNA reach plateau levels, mice are administered orally once a day for 4 weeks with one of the following: 40 mg/kg of Asunaprevir plus 30 mg/kg of Daclatasvir, 15 mg/kg of Ledipasvir plus 50 mg/kg of GS-558093 and 50 mg/kg of GS-558093 plus 400 mg/kg of Telaprevir. |

Daclatasvir is a potent HCV NS5A protein inhibitor, with mean EC50 values of 50 and 9 pM against genotype 1a and 1b replicons, respectively.
Daclatasvir (BMS-790052) is a small molecule inhibitor of the HCV NS5A protein that exhibits picomolar half-maximum effective concentrations (EC50) towards replicons expressing a broad range of HCV genotypes and the JFH-1 genotype 2a infectious virus in cell culture. Daclatasvir is a potent inhibitor of the JFH-1 genotype 2a infectious virus that replicates in cell culture (EC50=28 pM), an assay considered to be a more biologically relevant in vitro cell culture system. In addition, Daclatasvir displays similar potency in Huh-7, HeLa and HEK293T cells, demonstrating that the function(s) of NS5A inhibited by Daclatasvir is (are) highly conserved in different cellular environments[1].
In a randomized, double-blind, placebo-controlled, single ascending-dose study, Daclatasvir (BMS-790052) is administered at six dose levels to healthy, non-HCV-infected subjects over a range of 1 to 200 mg as an oral solution. Daclatasvir is safe and well tolerated up to 200 mg with no clinically relevant adverse effects. After oral administration, Daclatasvir is readily absorbed, with dose-proportional exposures over the studied dose range, and all subjects have drug concentrations greater than the protein-binding-adjusted EC90 for genotypes 1a and 1b, as measured in the replicon assay, at and beyond 24 h post-dose. (The protein binding-adjusted EC90 figures are derived from an analysis of the effect of the addition of human serum on antiviral activity in replicons. In the presence of 40% human serum, the EC90 for Daclatasvir is 383 pM (0.28 ng/mL) for the genotype 1a replicon and 49 pM (0.04 ng/mL) for the genotyope 1b replicon)[1]. Mice in each group that developed persistent HCV infection are divided into two treatment groups. One group receive 4 weeks of Asunaprevir/Daclatasvir treatment and the other group received 4 weeks of Ledipasvir/GS-558093 treatment. Asunaprevir/Daclatasvir therapy and Ledipasvir/GS-558093 therapy rapidly decease serum HCV RNA levels to below the sensitivity, and they are not detected after completion of the therapy except for two mice in the Ledipasvir/GS-558093 group[2].

Daclatasvir: A Review of Preclinical and Clinical Pharmacokinetics
Clin Pharmacokinet 2018 Aug;57(8):911-928.PMID:29353349DOI:10.1007/s40262-017-0624-3.
Daclatasvir is a first-in-class, highly selective, hepatitis C virus, non-structural protein 5a polymerase replication complex inhibitor with picomolar potency and broad genotypic coverage in vitro. Daclatasvir undergoes rapid absorption, with a time to reach maximum plasma concentration of 1-2 h and an elimination half-life of ~ 10 to 14 h observed in single-ascending dose studies. Steady state was achieved by day 4 in multiple-ascending dose studies. Daclatasvir can be administered without regard to food or pH modifiers. Daclatasvir exposure is similar between healthy subjects and subjects infected with hepatitis C virus. Intrinsic factors such as age, race, or sex do not impact Daclatasvir exposure. No dose adjustment is necessary for patients with any degree of hepatic or renal impairment. Daclatasvir has low-to-moderate clearance with the predominant route of elimination via cytochrome P450 3A4-mediated metabolism and P-glycoprotein excretion and intestinal secretion. Renal clearance is a minor route of elimination for Daclatasvir. As a result, the dose of Daclatasvir should be reduced from 60 to 30 mg once daily when co-administered with strong inhibitors of cytochrome P450 3A4. No dose adjustment is required when Daclatasvir is co-administered with moderate inhibitors of cytochrome P450 3A4. The dose of Daclatasvir should be increased from 60 to 90 mg once daily when co-administered with moderate inducers of cytochrome P450 3A4. Co-administration of Daclatasvir with strong inducers of cytochrome P450 3A4 is contraindicated. Concurrent medications with inhibitory effects on P-glycoprotein without concurrent inhibition of cytochrome P450 3A4 are unlikely to cause marked changes in Daclatasvir exposure, as the clearance of Daclatasvir is through both cytochrome P450 3A4 and P-glycoprotein. The potential for Daclatasvir to affect the pharmacokinetics of concomitantly administered drugs that are substrates of the cytochrome P450 enzyme system is low. In vitro, Daclatasvir is a weak-to-moderate inhibitor of transporters including organic cation transporter 1, P-glycoprotein, organic transporting polypeptide 1B1, organic transporting polypeptide 1B3, and breast cancer resistance protein, although in clinical studies, Daclatasvir has not altered the pharmacokinetics of concomitantly administered drugs that are substrates of these transporters to an appreciable degree, except for rosuvastatin. In summary, Daclatasvir is a hepatitis C virus, non-structural protein 5a-selective inhibitor with a well-characterized pharmacokinetic profile that forms part of potent and well-tolerated all-oral treatment regimens for chronic hepatitis C virus infection.
Daclatasvir: A Review in Chronic Hepatitis C
Drugs 2016 Sep;76(14):1381-91.PMID:27550544DOI:10.1007/s40265-016-0632-x.
The hepatitis C virus (HCV) NS5A replication complex inhibitor Daclatasvir (Daklinza(®)) is indicated for use in combination with sofosbuvir, with or without ribavirin, in a pangenotypic all-oral regimen. In patients with chronic HCV genotype 1 or 3 infection without cirrhosis, a 12-week regimen of Daclatasvir plus sofosbuvir achieved high sustained virological response rates 12 weeks' post-treatment (SVR12), regardless of prior treatment experience, according to the results of the AI444040 and ALLY-3 trials. In the ALLY-3+ trial, high SVR12 rates were achieved with a 12- or 16-week regimen of Daclatasvir plus sofosbuvir and ribavirin in patients with chronic HCV genotype 3 infection and advanced fibrosis or compensated cirrhosis. A Daclatasvir plus sofosbuvir-based regimen demonstrated efficacy in patients with chronic HCV genotype 1, 3 or 4 infection and advanced cirrhosis or post-transplant recurrence in the ALLY-1 trial, and in patients co-infected with HCV genotype 1, 3 or 4 and HIV-1 in the ALLY-2 trial. Results of clinical trials were supported by real-world data from early-access programmes that included high numbers of patients who would have been excluded from phase 3 trials because of advanced disease and/or concomitant medical conditions. Daclatasvir plus sofosbuvir with or without ribavirin was generally well tolerated. In conclusion, an all-oral regimen comprising Daclatasvir plus sofosbuvir with or without ribavirin is an important option for use in treatment-naive or treatment-experienced patients with chronic HCV genotype 1, 3 or 4 infection, including in patients with advanced liver disease, post-transplant recurrence and HIV-1 co-infection.
Daclatasvir: A NS5A Replication Complex Inhibitor for Hepatitis C Infection
Ann Pharmacother 2016 Jan;50(1):39-46.PMID:26486762DOI:10.1177/1060028015610342.
Objectives: To review the pharmacology, efficacy, and safety of Daclatasvir in the treatment of patients with chronic hepatitis C virus (HCV) infection. Data sources: A literature search through EMBASE and PubMed was conducted (January 1966 to August 2015) using the terms BMS-790052, Daclatasvir, and hepatitis C. References from retrieved articles were reviewed for any additional material. Additionally, the new drug application and prescribing information were retrieved. Study selection/data extraction: The literature search was limited to human studies published in English. Phase 1, 2, and 3 studies describing the pharmacology, pharmacokinetics, efficacy, and safety of Daclatasvir for HCV were identified. Data synthesis: Daclatasvir, a nonstructural 5A protein inhibitor, combined with sofosbuvir, is indicated for adult patients with chronic HCV genotype 3 regardless of treatment or cirrhosis status. The phase III ALLY-3 trial (n = 152) demonstrated that Daclatasvir taken once daily with sofosbuvir for 12 weeks was effective at achieving sustained virological response (SVR) rates in treatment-naïve (97%) and treatment-experienced (94%) patients without cirrhosis. Patients with cirrhosis had significantly lower SVR rates (58 and 69%, respectively). The most common adverse drug events associated with Daclatasvir and sofosbuvir in ALLY-3 were headache (20%), fatigue (19%), and nausea (12%). Conclusions: Daclatasvir, when combined with sofosbuvir, is an effective agent to treat HCV genotype 3, with SVR rates above 90% for patients without cirrhosis who are treatment naïve or experienced. SVR rates for treatment-naïve or -experienced patients with cirrhosis are not as robust (58%-69%).
Daclatasvir as a hepatitis C infection treatment option: an up-to-date evaluation
Expert Opin Pharmacother 2023 Feb;24(2):159-170.PMID:36369914DOI:10.1080/14656566.2022.2145883.
Introduction: Globally, it is estimated that 290,000 patients infected with hepatitis C virus (HCV) died from hepatitis C consequences, including cirrhosis and hepatocellular carcinoma in 2019. Although Daclatasvir (DCV), combined with sofosbuvir (SOF), is effective in HCV patients, the new pan-genotypic combinations are considered by many as more cost-effective and successful in eradicating HCV infection. Areas covered: This review discusses the safety, efficacy, and cost-effectiveness of DCV as an HCV treatment option based on real-world studies and pharmacoeconomic evaluations. Expert opinion: Real-life studies suggest that SOF/DCV has acceptable sustained virological response and can be used successfully to manage HCV. Nonetheless, the use of SOF/DCV is limited by the longer treatment duration in genotype (GT)-3 patients and the need for ribavirin (RBV) in treatment-experienced patients which increases the likelihood of adverse effects. DCV is likely to remain as a therapeutic option for the management of GT-1, GT-2, and GT-4 patients in resource limited settings, while GT-3 patients are more likely to benefit from RBV-free direct-acting antiviral combinations such as SOF/velpatasvir for 12 weeks or glecaprevir/pibrentasvir for 8 weeks. The introduction of generics for these new pan-genotypic drugs would likely eliminate the need for SOF/DCV in the near future.
Daclatasvir for the treatment of chronic hepatitis C
Expert Opin Pharmacother 2015;16(17):2679-88.PMID:26549010DOI:10.1517/14656566.2015.1109631.
Introduction: Following more than 20 years of Interferon (IFN)-based treatment for hepatitis C virus (HCV), the understanding of viral life cycle led to the development of new antiviral drugs directly targeting HCV replication steps. Daclatasvir (DCV) is a potent inhibitor of non-structural NS5A HCV protein with pangenotypic activity and low-moderate barrier to resistance suitable for IFN-free combination with other direct acting antivirals (DAAs). Areas covered: The present review summarizes DCV key pharmacokinetic features and results from Phase II and III trials, discussing also NS5A resistance. Main literature articles have been identified through Pubmed and Medline search; moreover, abstracts from recent international meetings on liver disease have been scrutinized. Expert opinion: DCV in combination with other DAAs has provided IFN-free regimens with increased efficacy and tolerability. However, suboptimal barrier to resistance and the rapid development of new second-generation NS5A inhibitors will probably make DCV a relatively short-lived drug.
