BMS-790052

BMS-790052 Uses, Dosage, Side Effects, Food Interaction and all others data.

BMS-790052 stops HCV viral RNA replication and protein translation by directly inhibiting HCV protein NS5A. NS5A is critical for HCV viral transcription and translation.

BMS-790052 is a direct-acting antiviral agent that targets the NS5A and causes a decrease in serum HCV RNA levels. It disrupts HCV replication by specifically inhibiting the critical functions of an NS5A protein in the replication complex . It is shown to cause downregulation of the hyperphosphorylation of NS5A. It does not appear to prolong the QT interval even when given at 3 times the maximum recommended dose.

Uses

BMS-790052 is used for combination with Sofosbuvir for the treatment of chronic hepatitis C virus (HCV) infection in adults.

BMS-790052 is also used to associated treatment for these conditions: Chronic Hepatitis C Genotype 1, Chronic Hepatitis C Virus (HCV) Infection, Chronic hepatitis C genotype 2, Chronic hepatitis C genotype 3

How BMS-790052 works

NS5A is a viral nonstructural phospoprotein that is part of a functional replication complex in charge of viral RNA genome amplification on endoplasmic reticulum membranes. It has the ability to bind to HCV RNA. It is shown to have two distinct functions in HCV RNA replication based on phosphorylated states. Maintaining the HCV replication complex is mediated by the cis-acting function of basally phosphorylated NS5A and the trans-acting function of hyperphosphorylated NS5A modulates HCV assembly and infectious particle formation . BMS-790052 is shown to disrupt hyperphosphorylated NS5A proteins thus interfere with the function of new HCV replication complexes. It is also reported that daclatasvir also blocks both intracellular viral RNA synthesis and virion assembly/secretion in vivo .

Dosage

BMS-790052 dosage

The recommended dose of BMS-790052 is 60 mg once daily, to be taken orally with or without meals. BMS-790052 must be administered in combination with other medicinal products.HCV-monoinfected or HCV/HIV coinfected patients with chronic hepatitis C without cirrhosis, including treatment-naïve patients and patients who failed on a treatment based on Peginterferon alfa & Ribavirin

  • All genotypes: BMS-790052 + Sofosbuvir for 12 weeks

HCV-monoinfected or HCV/HIV coinfected patients with chronic hepatitis C with compensated (Child-Pugh A) cirrhosis, including treatment-naïve patients and patients who failed on a treatment based on Peginterferon alfa & Ribavirin

  • Genotype 1,4,5,6: BMS-790052 + Sofosbuvir for 24 weeks or BMS-790052 + Sofosbuvir + Ribavirin for 12 weeks
  • Genotype 2: BMS-790052 + Sofosbuvir for 12 weeks
  • Genotype 3: BMS-790052 + Sofosbuvir + Ribavirin for 24 week

The dose of Ribavirin, when combined with BMS-790052, is weight-based (1000 or 1200 mg in patients <75 kg or ≥75 kg, respectively).

Side Effects

BMS-790052 in combination with Sofosbuvir: Fatigue, headache, nausea. BMS-790052 in combination with Peginterferon alfa and Ribavirin: The most frequently reported adverse reactions were fatigue, headache, pruritus, insomnia, influenza-like illness, dry skin, nausea, decreased appetite, alopecia, rash, asthenia, irritability, myalgia, anaemia, pyrexia, cough, dyspnoea, neutropenia, diarrhoea and arthralgia.

Toxicity

The most common adverse effects experienced in patients undergoing daclatasvir and sofosbuvir therapy include headache, fatigue, nausea and diarrhea. Similar side effects are seen when ribavirin is added, in addition to rash, insomnia, anemia, dizziness and somnolence. There are postmarketing cases that link serious symptomatic bradycardia with Daklinza when used in conjunction with sofosbuvir and amiodarone. Coadministration of these three drugs is not recommended unless there are no other alternatives.

Precaution

Bradycardia with Sofobuvir and Amiodarone coadministration: Serious symptomatic bradycardia may occur in patients taking amiodarone with Sofosbuvir in combination with BMS-790052, particularly in patients also receiving beta blockers, or those with underlying cardiac comorbidities and/or advanced liver disease. Coadministration of amiodarone with Sofobuvir in combination with BMS-790052 is not recommended.

BMS-790052 must not be administered as monotherapy. BMS-790052 must be administered in combination with other medicinal products for the treatment of chronic HCV infection

Interaction

Strong or moderate CYP3A4 or P-gp inducers (eg, phenytoin, carbamazepine, phenobarbital, rifampicin, systemic dexamethasone. Strong CYP3A4 inhibitors (eg, boceprevir, telaprevir, HIV protease inhibitors, cobicistat, macrolides, azole antifungals, calcium channel blockers). NNRTIs, dabigatran, digoxin, oral contraceptives, statins, amiodarone

Food Interaction

  • Avoid grapefruit products. Grapefruit inhibits the CYP3A metabolism of daclatasvir, which may increase its serum concentration. Dose changes may be necessary.
  • Avoid St. John's Wort. This herb induces the CYP3A metabolism of daclatasvir and may reduce its serum concentration. Co-administration of daclatasvir with St. John's Wort is contraindicated.
  • Take with or without food. BMS-790052 AUC and Cmax are slightly reduced when administered with food.

Volume of Distribution

The approximate volume of distribution of daclatasvir is 47 L in patients who was orally administered 60 mg tablet followed by 100 µg [13C,15N]-daclatasvir intravenously.

Elimination Route

Studies demonstrated that peak plasma concentrations typically occurred within 2 hours after administration of multiple oral doses ranging from 1 - 100 mg once daily. Steady state is reached after approximately 4 days of once-daily daclatasvir administration. The absolute bioavailability of the tablet formulation is 67%.

Half Life

Following multiple dose administration of daclatasvir in HCV-infected subjects, with doses ranging from 1 mg to 100 mg once daily, the terminal elimination half-life of daclatasvir ranged from approximately 12 to 15 hours.

Clearance

In subjects who received daclatasvir 60 mg tablet orally followed by 100 µg radiolabeled daclatasvir intravenously, the total clearance was 4.2 L/h.

Elimination Route

Approximately 88% of total dose of daclatasvir is eliminated into bile and feces in which 53% remains as unchanged form, while 6.6% of the total dose is eliminated primarily unchanged in the urine.

Pregnancy & Breastfeeding use

BMS-790052 should not be used during pregnancy or in women of childbearing potential not using contraception. Use of highly effective contraception should be continued for 5 weeks after completion of BMS-790052 therapy. It is not known whether daclatasvir is excreted in human milk.

Contraindication

Strong inducers of CYP3A, including phenytoin, carbamazepine, rifampicin, and St. John’s wort Hypersensitivity to the active substance or to any of the excipients
