Protocol

Kinase Assay [1]
In vitro inhibition of NS3/4A activity is determined using a fluorescence resonance energy transfer cleavage assay with the RetS1 peptide substrate, derived from the genotype 1a NS4A-4B junction, and bacterially expressed full-length NS3 protease domain, supplemented with an NS4A peptide. Briefly, NS3/4A is preincubated in the presence of TMC435350 for 10 min, and then the RetS1 substrate is added and fluorescence is continuously measured for 20 min (excitation, 355 nm; emission, 500 nm). Cleavage of the substrate is expressed as a percentage of the cleavage seen with the vehicle control.

Cell Assay [1]
Huh7-Luc cells are seeded at a density of 2,500 cells/well in a 384-well plate in Dulbecco's modified Eagle's medium plus 10% fetal calf serum and incubated with a range of concentrations of serially diluted simeprevir (TMC435350), in a final DMSO concentration of 0.5% in the absence of G418. After 72 h of incubation, Steady Lite reagent is added in a 1:1 ratio to the medium, and luciferase signal is measured using a ViewLux reader.

Animal Administration [1]
Twenty-four male specific-pathogen-free Sprague-Dawley rats, weighing between 200 and 300 g at the time of dosing, are divided into eight groups of three rats each. Seven groups are dosed orally (p.o.) by gastric intubation of a vitamin E acetate-d-α-tocopheryl polyethylene glycol 1000 succinate-polyethylene glycol 400 solution of Simeprevir (TMC435350) at 2 mL/kg body weight to provide a dose of 40 mg/kg. One group is dosed intravenously (i.v.) by slow bolus injection in a tail vein of a 20% 2-hydroxypropyl-β-cyclodextrin formulation of TMC435350 (containing TMC435350, 100 mg/mL 2-hydroxypropyl-β-cyclodextrin, 0.1 N NaOH to pH 8.0±0.1, and mannitol-and pyrogen-free water) at 2 mL/kg body weight to provide a dose of 4 mg/kg. Water and food are available ad libitum during the study.

Background on Simeprevir

Simeprevir is a potent inhibitor of HCV NS3/4A protease with Ki value of 0.36 nM [1].
The hepatitis C virus (HCV) NS3/4A protease is a serine protease encoded by HCV and is responsible for cleavage at four sites of the HCV polyprotein. It is essential for viral replication [1].
In Huh-7-Rep cells, Simeprevir inhibited HCV replication with EC50 of 7.8 nM [1]. In the Huh7-Luc HCV genotype 1b replicon cell line, Simeprevir inhibited HCV replication with EC50 and EC90 values of 8 nM and 24 nM respectively in a dose dependent way [2].
In ninety-two naive, HCV genotype 1-infected patients, treatment with Simeprevir (50 or 100 mg QD) for 12 or 24 weeks and peginterferon α-2a/ribavirin (PegIFNα-2a/RBV) for 24 or 48 weeks or PegIFN α-2a/RBV for 48 weeks lonely (PR48 group), RNA reductions in the 4 week were -5.2,-5.2 and-2.9 log10IU/mL for Simeprevir 50 mg combined, 100 mg combined and PR48 groups, respectively, which suggested Simeprevir reduced HCV RNA more rapidly and substantially. Also, Simeprevir increased the virologic response rates [3].

Efficacy, safety, and pharmacokinetics of simeprevir, daclatasvir, and ribavirin in patients with recurrent hepatitis C virus genotype 1b infection after orthotopic liver transplantation: The Phase II SATURN study.[Pubmed:28295849]

Transpl Infect Dis. 2017 Jun;19(3).

BACKGROUND: Recurrent hepatitis C virus (HCV) infection following liver transplantation is associated with accelerated progression to graft failure and reduced patient survival. METHODS: The Phase II, open-label SATURN study (NCT01938625) investigated the combination of Simeprevir (SMV), daclatasvir (DCV), and ribavirin (RBV) administered for 24 weeks in 35 patients with recurrent HCV genotype (GT) 1b infection after orthotopic liver transplantation (OLT). RESULTS: High rates of both on-treatment and sustained virologic response 12 weeks after end of treatment (SVR12) were achieved in patients who were either treatment-naive or had failed post-OLT treatment with peginterferon and RBV. Overall, 91% of patients (32/35) achieved SVR12. The combination was generally well tolerated, with an adverse event profile consistent with that observed in previous clinical trials of SMV or DCV separately. Co-administration of SMV with cyclosporine resulted in significantly increased SMV plasma exposures, which was not the case with the co-administration of SMV with tacrolimus. Therefore, the concomitant use of SMV with cyclosporine is not recommended. CONCLUSION: The interferon-free combination of SMV, DCV, and RBV administered for 24 weeks was shown to be effective and well tolerated in the treatment of post-OLT HCV GT1b-infected patients.

Sofosbuvir-Daclatasvir-Simeprevir Plus Ribavirin in Direct-Acting Antiviral-Experienced Patients With Hepatitis C.[Pubmed:28369411]

Clin Infect Dis. 2017 Jun 1;64(11):1615-1618.

We assessed the broadly used, off-label combination of sofosbuvir, daclatasvir, Simeprevir, and ribavirin in direct-acting antiviral-experienced patients, as recommended in current guidelines despite scarce data. After 24 weeks' treatment, sustained virological response 12 weeks after the end of treatment was achieved in 6 patients (60%). Two cirrhotic patients relapsed and 2 discontinued treatment due to serious adverse events.

Efficacy and safety of telaprevir- and simeprevir-based triple therapies for older patients with chronic hepatitis C.[Pubmed:28261382]

World J Hepatol. 2017 Feb 18;9(5):252-262.

AIM: To evaluate and compare the efficacy and safety of telaprevir (TVR)-and Simeprevir (SMV)-based triple therapies in elderly patients, specifically patients aged 66 years or older. METHODS: The present study enrolled 112 and 76 Japanese patients with chronic hepatitis C virus genotype 1b infection who were treated with a 12-wk TVR-based or SMV-based triple therapy, respectively, followed by a dual therapy that included pegylated interferon alpha and ribavirin (RBV) for 12 wk. The patients were categorized into two groups according to age as follows: A younger group of patients aged 65 years old. Among the patients treated with TVR-based triple therapy, 34 patients were included in the older group. The median ages were 56 years (range: 28-65 years) in the younger group and 69 years (range: 66-81 years) in the older group. Among the patients treated with SMV-based triple therapy, 39 patients were included in the older group. The median ages were 59 years (range: 36-65 years) in the younger group and 71 years (range: 66-86 years) in the older group. The clinical, biochemical and virological data were analyzed before and during treatment. RESULTS: Among the patients treated with the TVR-based triple therapy, no significant difference in the sustained virological response (SVR) was found between the younger (80.8%) and older (88.2%) groups. The SVR rates for patients with the interleukin 28B (IL28B) (rs8099917) TG/GG-genotypes (73.9% and 60.0% in the younger and older groups, respectively) were significantly lower than for patients with the IL28B TT-genotype (86.3% and 92.9%, respectively). The cumulative exposure to RBV for the entire 24-wk treatment period (as a percentage of the target dose) was significantly higher in the younger group than in the older group (91.7% vs 66.7%, respectively, P < 0.01), but the cumulative exposure to TVR was not significantly different between the younger and older groups (91.6% vs 81.9%, respectively). A multivariate analysis identified the TT-genotype of IL28B (OR = 8.160; 95%CI: 1.593-41.804, P = 0.012) and the adherence of RBV (> 60%) (OR = 11.052; 95%CI: 1.160-105.273, P = 0.037) as independent factors associated with the SVR. Adverse events resulted in discontinuation of the treatment in 11.3% and 14.7% of the younger and older groups, respectively. Among the patients treated with the SMV-based triple therapy, no significant difference in the SVR rare was found between the younger (81.1%) and older (82.1%) groups. The SVR rates for patients with the IL28B TG/GG-genotypes (77.8% and 64.7% in the younger and older groups, respectively) were significantly lower than for patients with the IL28B TT-genotype (88.2% and 100%, respectively). A multivariate analysis identified the TT-genotype of IL28B as an independent factor associated with the SVR (OR = 9.677; 95%CI: 1.114-84.087, P = 0.040). Adverse events resulted in discontinuation of the treatment in 7.0% and 14.3% of patients in the younger and older groups, respectively. CONCLUSION: Both TVR- and SMV-based triple therapies can be successfully used to treat patients aged 66 years or older with genotype 1b chronic hepatitis C. Genotyping of the IL28B indicates a potential to achieve SVR in these difficult-to-treat elderly patients.

Aplastic Anemia and Severe Myelosuppression with Boceprevir or Simeprevir-Containing Hepatitis C Virus Treatment.[Pubmed:28233734]

Ann Hepatol. 2017 March-April;16(2):312-317.

The addition of the new protease inhibitors (PIs) to peg-interferon (IFN) and ribavirin (RBV), approved for chronic hepatitis C, has clearly improved sustained virological response (SVR) rates although several adverse events have been reported with this regimens, including mild hematological toxicity. Moreover, severe pancytopenia and aplastic anemia during triple therapy with telaprevir has recently been described in seven patients. We report here two cases of severe agranulocytosis/aplastic anemia using boceprevir or Simeprevir in interferon-based combination and 2 additional cases of severe myelosupression in IFN-free therapy with sofosbuvir and Simeprevir plus RBV. Our observations suggest that PIs could have a sort of class-effect in developing severe hematologic toxicity or, at least, an additive interaction with other potentially myelotoxic agents such as IFN or RBV that are used in the classical regimens against HCV. Unfortunately, the mechanisms behind this phenomenon are currently unknown. In conclusion, given the lifethreatening character of these complications, close monitoring is mandatory in patients under PIs based therapy to promptly detect serious hematological toxicities and to carefully evaluate treatment discontinuation. Prospective studies assessing the usefulness of RBV in the era of new IFN-free combinations are needed.
