What is Virkil?

Darunavir, cobicistat, emtricitabine, and Virkil alafenamide combination is used to treat human immunodeficiency virus (HIV) infection. HIV is the virus that causes acquired immune deficiency syndrome (AIDS). Darunavir, cobicistat, emtricitabine, and Virkil alafenamide is usually given to patients who have yet not received any medicine for HIV infection.

Darunavir, cobicistat, emtricitabine, and Virkil alafenamide combination will not cure or prevent HIV infection or AIDS. It helps keep HIV from reproducing and appears to slow down the destruction of the immune system. This may help delay problems that are usually related to AIDS or HIV disease from occurring. Darunavir, cobicistat, emtricitabine, and Virkil alafenamide will not keep you from spreading HIV to other people. People who receive darunavir, cobicistat, emtricitabine, and Virkil alafenamide may continue to have other problems usually related to AIDS or HIV disease.

Darunavir, cobicistat, emtricitabine, and Virkil alafenamide is available only with your doctor's prescription.

Virkil indications

infoAn indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

HIV-1 Infection: Virkil is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults and pediatric patients 12 years of age and older.

The following points should be considered when initiating therapy with Virkil for the treatment of HIV-1 infection: Virkil should not be used in combination with STRIBILD, TRUVADA or other products containing Virkil disoproxil fumarate.

Chronic Hepatitis B: Virkil is indicated for the treatment of chronic hepatitis B in adults. The following points should be considered when initiating therapy with Virkil for the treatment of HBV infection: The indication in adults is based on safety and efficacy data from treatment of subjects who were nucleoside-treatment-naïve and subjects who were treatment-experienced with documented resistance to lamivudine. Subjects were adults with HBeAg-positive and HBeAg-negative chronic hepatitis B with compensated liver disease.

Virkil was evaluated in a limited number of subjects with chronic hepatitis B and decompensated liver disease..

The numbers of subjects in clinical trials who had adefovir resistance-associated substitutions at baseline were too small to reach conclusions of efficacy.

Virkil is indicated for the treatment of chronic hepatitis B in adolescents 12 to <18 years of age with: Compensated liver disease and evidence of immune active disease, i.e. active viral replication, persistently elevated serum ALT levels and histological evidence of active inflammation and/or fibrosis.

How should I use Virkil?

Use Virkil powder as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • An extra patient leaflet is available with Virkil powder. Talk to your pharmacist if you have questions about this information.
  • Take Virkil powder by mouth with food as directed.
  • Only use the dosing scoop that comes with Virkil powder to measure your dose. Ask your pharmacist for help if you are unsure of how to measure your dose.
  • Wash and dry your hands immediately before preparing your dose.
  • Mix the prescribed dose of Virkil powder with 1/4 to 1/2 cup (2 to 4 oz) of a soft food that can be swallowed without chewing (eg, applesauce, baby food, yogurt). Do NOT mix Virkil powder with liquid. It may float to the top even after stirring.
  • Stir the mixture with a spoon until it is well mixed. Take your dose right away after mixing to avoid a bad taste.
  • Wash and dry the dosing scoop after each use. Do NOT store it in the bottle.
  • Continue to take Virkil powder even if you feel well. Do not miss any doses.
  • Taking Virkil powder at the same time each day will help you remember to take it.
  • Do not suddenly stop taking Virkil powder without checking with your doctor. This may cause the virus to become less sensitive to this or other medicines. If you have hepatitis B, your condition could become worse if you suddenly stop taking Virkil powder.
  • If you miss a dose of Virkil powder, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Virkil powder.

Uses of Virkil in details

infoThere are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Virkil is used in combination with other antiviral drugs in the treatment of human immunodeficiency virus (HIV) infections. It may also be used in very limited cases of long-term infections of liver caused by hepatitis B virus.

Virkil description

Virkil is the brand name for Virkil disoproxil fumarate (a prodrug of Virkil) which is a fumaric acid salt of bis-isopropoxycarbonyloxymethyl ester derivative of Virkil. In vivo Virkil disoproxil fumarate is converted to Virkil, an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5'-monophosphate. Virkil exhibits activity against HIV-1 reverse transcriptase.

The chemical name of Virkil disoproxil fumarate is 9-[(R)2[[bis[[(isopropoxycarbonyl)oxy]methoxy]phosphinyl]methoxy]propyl]adenine fumarate (1:1). It has a molecular formula of C19H30N5O10P·C4H4O4 and a molecular weight of 635.52.

Virkil disoproxil fumarate is a white to off-white crystalline powder with a solubility of 13.4 mg/mL in distilled water at 25°C. It has an octanol/phosphate buffer (pH 6.5) partition coefficient (log p) of 1.25 at 25°C.

Virkil tablets are for oral administration. Each tablet contains 300 mg of Virkil disoproxil fumarate, which is equivalent to 245 mg of Virkil disoproxil.

Excipients/Inactive Ingredients: Croscarmellose sodium, lactose monohydrate, magnesium stearate, microcrystalline cellulose, and pregelatinized starch. The tablets are coated with Opadry II Y–30–10671–A, which contains FD&C blue #2 aluminum lake, hypromellose 2910, lactose monohydrate, titanium dioxide, and triacetin.

In this insert, all dosages are expressed in terms of Virkil disoproxil fumarate except where otherwise noted.

Recommended Dose In Adults And Pediatric Patients 12 Years Of Age And Older (35 kg or more)

For the treatment of HIV-1 or chronic hepatitis B: The dose is one 300 mg Virkil tablet once daily taken orally, without regard to food.

For patients unable to swallow Virkil tablets, the oral powder formulation (7.5 scoops) may be used.

In the treatment of chronic hepatitis B, the optimal duration of treatment is unknown. Safety and efficacy in pediatric patients with chronic hepatitis B weighing less than 35 kg have not been established.

Recommended Dose In Pediatric Patients 2 Years To Less Than 12 Years Of Age

HIV-1 Infection

For the treatment of HIV-1 in pediatric patients 2 years of age and older, the recommended oral dose of Virkil is 8 mg of Virkil disoproxil fumarate per kilogram of body weight (up to a maximum of 300 mg) once daily administered as oral powder or tablets.

Virkil oral powder should be measured only with the supplied dosing scoop. One level scoop delivers 1 g of powder which contains 40 mg of Virkil disoproxil fumarate. Virkil oral powder should be mixed in a container with 2 to 4 ounces of soft food not requiring chewing (e.g., applesauce, baby food, yogurt). The entire mixture should be ingested immediately to avoid a bitter taste. Do not administer Virkil oral powder in a liquid as the powder may float on top of the liquid even after stirring. Further patient instructions on how to administer Virkil oral powder with the supplied dosing scoop are provided in the FDA-approved patient labeling (Patient Information).

Virkil is also available as tablets in 150, 200, 250 and 300 mg strengths for pediatric patients who weigh greater than or equal to 17 kg and who are able to reliably swallow intact tablets. The dose is one tablet once daily taken orally, without regard to food.

Tables 1 and 2 contain dosing recommendations for Virkil oral powder and tablets based on body weight. Weight should be monitored periodically and the Virkil dose adjusted accordingly.

Dose Adjustment For Renal Impairment In Adults

Significantly increased drug exposures occurred when Virkil was administered to subjects with moderate to severe renal impairment. Therefore, the dosing interval of Virkil tablets 300 mg should be adjusted in patients with baseline creatinine clearance below 50 mL/min using the recommendations in Table 3. These dosing interval recommendations are based on modeling of single-dose pharmacokinetic data in non-HIV and non-HBV infected subjects with varying degrees of renal impairment, including end-stage renal disease requiring hemodialysis. The safety and effectiveness of these dosing interval adjustment recommendations have not been clinically evaluated in patients with moderate or severe renal impairment, therefore clinical response to treatment and renal function should be closely monitored in these patients. There are no data to recommend use of Virkil tablets 150, 200 or 250 mg or Virkil oral powder in patients with renal impairment.

No dose adjustment of Virkil tablets 300 mg is necessary for patients with mild renal impairment (creatinine clearance 50–80 mL/min). Routine monitoring of estimated creatinine clearance, serum phosphorus, urine glucose, and urine protein should be performed in patients with mild renal impairment.

Table 3 : Dosage Adjustment for Patients with Altered Creatinine Clearance

Creatinine Clearance (mL/min) Generally once weekly assuming three hemodialysis sessions a week of approximately 4 hours duration. Virkil should be administered following completion of dialysis.

The pharmacokinetics of Virkil have not been evaluated in non-hemodialysis patients with creatinine clearance below 10 mL/min; therefore, no dosing recommendation is available for these patients.

No data are available to make dose recommendations in pediatric patients with renal impairment.

What other drugs will affect Virkil?

sponsored

This section describes clinically relevant drug interactions with Virkil. Drug interactions trials are described elsewhere in the labeling.

Didanosine

Coadministration of Virkil and didanosine should be undertaken with caution and patients receiving this combination should be monitored closely for didanosineassociated adverse reactions. Didanosine should be discontinued in patients who develop didanosine-associated adverse reactions.

When administered with Virkil, Cmax and AUC of didanosine increased significantly. The mechanism of this interaction is unknown. Higher didanosine concentrations could potentiate didanosine-associated adverse reactions, including pancreatitis and neuropathy. Suppression of CD4cell counts has been observed in patients receiving Virkil with didanosine 400 mg daily.

In patients weighing greater than 60 kg, the didanosine dose should be reduced to 250 mg once daily when it is coadministered with Virkil. In patients weighing less than 60 kg, the didanosine dose should be reduced to 200 mg once daily when it is coadministered with Virkil. When coadministered, Virkil and didanosine EC may be taken under fasted conditions or with a light meal (less than 400 kcal, 20% fat). For additional information on coadministration of Virkil and didanosine, please refer to the full prescribing information for didanosine.

HIV-1 Protease Inhibitors

Virkil decreases the AUC and Cmin of atazanavir. When coadministered with Virkil, it is recommended that atazanavir 300 mg is given with ritonavir 100 mg. Virkil should not be coadministered with atazanavir without ritonavir.

Lopinavir/ritonavir, atazanavir coadministered with ritonavir, and darunavir coadministered with ritonavir have been shown to increase Virkil concentrations. Virkil disoproxil fumarate is a substrate of Pglycoprotein (Pgp) and breast cancer resistance protein (BCRP) transporters. When Virkil disoproxil fumarate is coadministered with an inhibitor of these transporters, an increase in absorption may be observed. Patients receiving Virkil concomitantly with lopinavir/ritonavir, ritonavir-boosted atazanavir, or ritonavir-boosted darunavir should be monitored for Virkil-associated adverse reactions. Virkil should be discontinued in patients who develop Virkil-associated adverse reactions.

Hepatitis C Antiviral Agents

Coadministration of Virkil disoproxil fumarate and HARVONI (ledipasvir/sofosbuvir) has been shown to increase Virkil exposure.

In patients receiving Virkil concomitantly with HARVONI without an HIV-1 protease inhibitor/ritonavir or an HIV-1 protease inhibitor/cobicistat combination, monitor for adverse reactions associated with Virkil disoproxil fumarate.

In patients receiving Virkil concomitantly with HARVONI and an HIV-1 protease inhibitor/ritonavir or an HIV-1 protease inhibitor/cobicistat combination, consider an alternative HCV or antiretroviral therapy, as the safety of increased Virkil concentrations in this setting has not been established. If coadministration is necessary, monitor for adverse reactions associated with Virkil disoproxil fumarate.

Drugs Affecting Renal Function

Since Virkil is primarily eliminated by the kidneys, coadministration of Virkil with drugs that reduce renal function or compete for active tubular secretion may increase serum concentrations of Virkil and/or increase the concentrations of other renally eliminated drugs. Some examples include, but are not limited to, cidofovir, acyclovir, valacyclovir, ganciclovir, valganciclovir, aminoglycosides (e.g., gentamicin), and high-dose or multiple NSAIDs.

In the treatment of chronic hepatitis B, Virkil should not be administered in combination with HEPSERA (adefovir dipivoxil).

Virkil side effects

What are the possible side effects of Virkil?

The following adverse reactions are discussed in other sections of the labeling:

  • Lactic Acidosis/Severe Hepatomegaly with Steatosis
  • Severe Acute Exacerbation of Hepatitis B
  • New Onset or Worsening of Renal Impairment

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adverse Reactions in Adult Subjects with Chronic Hepatitis B and Compensated Liver Disease

The safety assessment of Virkil was based on pooled data through the Week 48 data analysis from 1298 subjects in two randomized, double-blind, active-controlled trials, Study 108 and Study 110, in adult subjects with chronic hepatitis B and compensated liver disease. A total of 866 subjects received Virkil 25 mg once daily.

The proportion of subjects who discontinued treatment with Virkil or Virkil disoproxil fumarate due to adverse reactions of any severity was 1.0% and 1.2%, respectively. Table 1 displays the frequency of the adverse reaction (all Grades) greater than or equal to 5% in the Virkil group.

Renal Laboratory Tests

In a pooled analysis of Studies 108 and 110 in adult subjects with chronic hepatitis B and a median baseline eGFR of 106 and 105 mL per minute (for the Virkil and Virkil disoproxil fumarate [TDF] groups, respectively), mean serum creatinine increased by less than 0.1 mg/dL and median serum phosphorus decreased by 0.1 mg/ dL in both treatment groups. Median change from baseline in eGFR was -1.2 mL per minute in the Virkil group and -5.4 mL per minute in those receiving TDF. The long-term clinical significance of these renal laboratory changes on adverse reaction frequencies between Virkil and TDF is not known.

Decrease in Bone Mineral Density

In a pooled analysis of Studies 108 and 110, the mean percentage change in bone mineral density (BMD) from baseline to Week 48 as assessed by dual-energy X-ray absorptiometry (DXA) was -0.6% with Virkil compared to -2.4% with TDF at the lumbar spine and -0.2% compared to -1.9% at the total hip. BMD declines of 5% or greater at the lumbar spine were experienced by 6% of Virkil subjects and 20% of TDF subjects. BMD declines of 7% or greater at the femoral neck were experienced by 3% of Virkil subjects and 6% of TDF subjects. The long-term clinical significance of these BMD changes is not known.

Laboratory Abnormalities

The frequency of laboratory abnormalities (Grades 3–4) occurring in at least 2% of subjects receiving Virkil in Studies 108 and 110 are presented in Table 2.
