Cautions
HCV and HBV Coinfection
- Hepatitis B virus (HBV) reactivation reported in HCV/HBV coinfected patients undergoing or had completed treatment with HCV direct-acting antivirals, and who were not receiving HBV antiviral therapy
- Some cases have resulted in fulminant hepatitis, hepatic failure, and death; cases have been reported in patients who are HBsAg positive and also in patients with serologic evidence of resolved HBV infection (eg, HBsAg negative and anti-HBc positive)
- HBV reactivation also reported in patients receiving certain immunosuppressants or chemotherapeutic agents
- Risk of HBV reactivation associated with treatment with HCV direct-acting antivirals may be increased in these patients
- HBV reactivation is characterized as abrupt increase in HBV replication manifesting as a rapid increase in serum HBV DNA level; in patients with resolved HBV infection, reappearance of HBsAg can occur
- Reactivation of HBV replication may be accompanied by hepatitis, eg, increases in aminotransferase levels and, in severe cases, increases in bilirubin levels, liver failure, and death can occur
- Test all patients for evidence of current or prior HBV infection by measuring HBsAg and anti-HBc before initiating HCV therapy
- In patients with serologic evidence of HBV infection, monitor for clinical and laboratory signs of hepatitis flare or HBV reactivation during HCV treatment and during post-treatment follow-up; initiate appropriate patient management for HBV infection as clinically indicated

- If drug combination administered with ribavirin, the warnings and precautions for ribavirin, in particular, the pregnancy avoidance warning, apply to this combination regimen; refer to ribavirin prescribing information for a full list of warnings and precautions for ribavirin
- Ledipasvir and sofosbuvir are substrates of P-gp and BCRP; coadministration with P-gp inducers (eg, rifampin, St. John’s wort) is not recommended; may significantly decrease ledipasvir and sofosbuvir plasma concentrations and reduce therapeutic effect
- Ledipasvir is an inhibitor of P-gp and BCRP; may increase intestinal absorption of coadministered substrates for these transporters
- Coadministration of ledipasvir with acid-reducing agents may decrease ledipasvir solubility, resulting in decreased serum concentrations
- Frequent monitoring of relevant laboratory parameters (eg, International Normalized Ratio [INR] in patients taking warfarin, blood glucose levels in diabetic patients) or drug concentrations of concomitant medications such as cytochrome P450 substrates with a narrow therapeutic index (eg, certain immunosuppressants) is recommended to ensure safe and effective use; dose adjustments of concomitant medications may be necessary
-
Bradycardia with amiodarone coadministration
- Postmarketing cases of symptomatic bradycardia, as well as fatal cardiac arrest and cases requiring pacemaker intervention, reported when the drug combination is administered with amiodarone
- Bradycardia has generally occurred within hours to days, but cases reported up to 2 weeks after initiating HCV treatment; patients also taking beta-blockers, or those with underlying cardiac comorbidities and/or advanced liver disease, may be at increased risk for symptomatic bradycardia with coadministration of amiodarone
- Bradycardia generally resolved after discontinuation of HCV treatment; the mechanism for this effect is unknown
- Coadministration of amiodarone not recommended; for patients taking amiodarone with no other alternative, viable treatment options should counsel patients about risk of serious symptomatic bradycardia; cardiac monitoring in an in-patient setting for first 48 hours of coadministration is recommended, after which outpatient or self-monitoring of heart rate should occur on a daily basis through at least first 2 weeks of treatment; patients on the drug combination who need to take amiodarone should use the same approach as described above
- Due to amiodarone’s long half-life, patients discontinuing amiodarone should undergo cardiac monitoring prior to starting therapy; patients who develop signs or symptoms of bradycardia, including near-fainting or fainting, dizziness or lightheadedness, malaise, weakness, excessive tiredness, shortness of breath, chest pains, confusion or memory problems should seek medical evaluation immediately
Pregnancy & Lactation
Pregnancy
If the drug combination is administered with ribavirin, the combination regimen is contraindicated in pregnant women and in men whose female partners are pregnant; refer to ribavirin prescribing information for more information on ribavirin-associated risks of use during pregnancy
No adequate human data are available to establish whether or not the drug combination poses a risk to pregnancy outcomes; in animal reproduction studies, no evidence of adverse developmental outcomes was observed with the drug combination ledipasvir or sofosbuvir at exposures greater than those in humans at the recommended human dose (RHD)
Lactation
It is not known whether ledipasvir or sofosbuvir, the drug combination, or their metabolites are present in human breast milk, affect human milk production or have effects on the breastfed infant.
The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for the drug combination and any potential adverse effects on the breastfed child from the drug combination or from the underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Ledipasvir: Inhibits HCV NS5A protein, which is required for viral replication; resistance selection in cell culture and cross-resistance studies indicate ledipasvir targets NS5A as its mode of action
Sofosbuvir: Nucleotide prodrug that undergoes metabolism to the active uridine analog triphosphate, an inhibitor of HCV NS5B RNA-dependent polymerase; its inhibition, in turn, suppresses viral replication
Absorption
Peak plasma concentration
- ledipasvir: 4-4.5 hr
- sofosbuvir: 0.8-1 hr
- GS-331007: 3.5-4 hr
Peak plasma level
- ledipasvir: 323 ng/mL
- sofosbuvir: 618 ng/mL
- GS-331007: 707 ng/mL
AUC
- ledipasvir: 7,290 ng•hr/mL
- sofosbuvir: 1,320 ng•hr/mL
- GS-331007: 12,000 ng•hr/mL
Distribution
Protein bound
- ledipasvir: >99.8%
- sofosbuvir: 61-65%
- GS-331007: minimal
Metabolism
ledipasvir: No detectable metabolism
sofosbuvir: Extensively metabolized in liver to form the pharmacologically active nucleoside analog triphosphate GS-461203; dephosphorylation results in formation of GS331007 (accounts for <90% of total systemic exposure of sofosbuvir)
Elimination
Half-life, terminal
- ledipasvir: 47 hr
- sofosbuvir: 0.5 hr
- GS-331007: 27 hr
Excretion
- ledipasvir: >98% feces (mostly unchanged); <1% urine
- GS-331007: 14% feces; 80% urine; 2.5% expired air

LEDIPASVIR/SOFOSBUVIR - ORAL
(le-DIP-as-vir/soe-FOS-buer-vir)
COMMON BRAND NAME(S): Harvoni
WARNING: Although this medication is used to treat hepatitis C, it may rarely make another liver problem called hepatitis B get worse. Before starting this medication, tell your doctor if you have ever had hepatitis B. Tell your doctor right away if you have new or worsening symptoms of liver disease, such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, dark urine or yellowing eyes/skin.
USES: This medication is a combination of ledipasvir and sofosbuvir and is used to treat chronic (long-lasting) hepatitis C, a viral infection of the liver. It may sometimes be used with another antiviral medication (ribavirin). These drugs work by reducing the amount of hepatitis C virus in your body, which helps your immune system fight the infection and may help your liver recover. Chronic hepatitis C infection can cause serious liver problems such as scarring (cirrhosis), or liver cancer.It is not known if this treatment can prevent you from passing the virus to others. Do not share needles, and practice "safer sex" (including the use of latex condoms) to lower the risk of passing the virus to others.
HOW TO USE: Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start taking ledipasvir/sofosbuvir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth with or without food as directed by your doctor, usually once daily. The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on weight.If you are using the pellet form of this medication, gently shake the packet before use.
