  • No data
  • Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued anti-hepatitis B therapy, including entecavir. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue anti-hepatitis B therapy. If appropriate, initiation of anti-hepatitis B therapy may be warranted [].
  • Limited clinical experience suggests there is a potential for the development of resistance to HIV (human immunodeficiency virus) nucleoside reverse transcriptase inhibitors if entecavir tablets are used to treat chronic hepatitis B virus (HBV) infection in patients with HIV infection that is not being treated. Therapy with entecavir tablets are not recommended for HIV/HBV co-infected patients who are not also receiving highly active antiretroviral therapy (HAART) [].
  • Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogue inhibitors alone or in combination with antiretrovirals [].
  • WARNING: SEVERE ACUTE EXACERBATIONS OF HEPATITIS B, PATIENTS CO-INFECTED WITH HIV AND HBV, and LACTIC ACIDOSIS AND HEPATOMEGALY
  • See full prescribing information for complete boxed warning
  • Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued anti-hepatitis B therapy, including entecavir. Hepatic function should be monitored closely for at least several months after discontinuation. Initiation of anti-hepatitis B therapy may be warranted. ()
  • Entecavir tablets are not recommended for patients co-infected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) who are not also receiving highly active antiretroviral therapy (HAART), because of the potential for the development of resistance to HIV nucleoside reverse transcriptase inhibitors. ()
  • Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogue inhibitors. ()
  • Entecavir tablets are indicated for the treatment of chronic hepatitis B virus infection in adults and pediatric patients 2 years of age and older with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (ALT or AST) or histologically active disease.
  • Entecavir tablets are a hepatitis B virus nucleoside analogue reverse transcriptase inhibitor indicated for the treatment of chronic hepatitis B virus infection in adults and children at least 2 years of age with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (ALT or AST) or histologically active disease.

  • The following adverse reactions are discussed in other sections of the labeling:
  • To report SUSPECTED ADVERSE REACTIONS, contact Teva Pharmaceuticals USA, Inc. at 1-888-838-2872 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
  • In adults, the most common adverse reactions (u22653%, all severity grades) are headache, fatigue, dizziness, and nausea. The adverse reactions observed in pediatric patients were consistent with those observed in adults. ()
  • Since entecavir is primarily eliminated by the kidneys [], coadministration of entecavir with drugs that reduce renal function or compete for active tubular secretion may increase serum concentrations of either entecavir or the coadministered drug. Coadministration of entecavir with lamivudine, adefovir dipivoxil, or tenofovir disoproxil fumarate did not result in significant drug interactions. The effects of coadministration of entecavir with other drugs that are renally eliminated or are known to affect renal function have not been evaluated, and patients should be monitored closely for adverse events when entecavir is coadministered with such drugs.
  • No data
  • Liver transplant recipients: Limited data on safety and efficacy are available. ()
  • There is limited experience of entecavir overdosage reported in patients. Healthy subjects who received single entecavir doses up to 40 mg or multiple doses up to 20 mg/day for up to 14 days had no increase in or unexpected adverse events. If overdose occurs, the patient must be monitored for evidence of toxicity, and standard supportive treatment applied as necessary.
  • Following a single 1 mg dose of entecavir, a 4-hour hemodialysis session removed approximately 13% of the entecavir dose.
  • Entecavir, USPu00a0is a guanosine nucleoside analogue with selective activity against HBV. The chemical name for entecavir is 2-amino-1,9-dihydro-9-[()-4-hydroxy-3-(hydroxymethyl)-2-methylenecyclopentyl]-6-purin-6-one, monohydrate. Entecavir has the following structural formula:
  • CHNOu2022HO M.W. 295.3
  • Entecavir monohydrate, USP is a white to off-white crystalline powder. It is slightly soluble in water (2.4 mg/mL), and the pH of the saturated solution in water is 7.9 at 25u00b0 C u00b1 0.5u00b0 C.
  • Each film-coated tablet, for oral administration, contains either 0.533 mg or 1.065 mg of entecavir monohydrate, USP equivalent to 0.5 mg or 1 mg of entecavir. In addition, each film-coated tablet contains the following inactive ingredients: crospovidone, magnesium stearate, mannitol, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, pregelatinized corn starch, talc, and titanium dioxide. In addition, the 1 mg contains FD&C blue #2 aluminum lake, FD&C red #40 aluminum lake, and iron oxide yellow.
  • No data
  • Carcinogenesis
  • Long-term oral carcinogenicity studies of entecavir in mice and rats were carried out at exposures up to approximately 42 times (mice) and 35 times (rats) those observed in humans at the highest recommended dose of 1 mg/day. In mouse and rat studies, entecavir was positive for carcinogenic findings. It is not known how predictive the results of rodent carcinogenicity studies may be for humans .
  • In mice, lung adenomas were increased in males and females at exposures 3 and 40 times those in humans. Lung carcinomas in both male and female mice were increased at exposures 40 times those in humans. Combined lung adenomas and carcinomas were increased in male mice at exposures 3 times and in female mice at exposures 40 times those in humans. Tumor development was preceded by pneumocyte proliferation in the lung, which was not observed in rats, dogs, or monkeys administered entecavir, supporting the conclusion that lung tumors in mice may be a species-specific event. Hepatocellular carcinomas were increased in males and combined liver adenomas and carcinomas were also increased at exposures 42 times those in humans. Vascular tumors in female mice (hemangiomas of ovaries and uterus and hemangiosarcomas of spleen) were increased at exposures 40 times those in humans. In rats, hepatocellular adenomas were increased in females at exposures 24 times those in humans; combined adenomas and carcinomas were also increased in females at exposures 24 times those in humans. Brain gliomas were induced in both males and females at exposures 35 and 24 times those in humans. Skin fibromas were induced in females at exposures 4 times those in humans.
  • Mutagenesis
  • Entecavir was clastogenic to human lymphocyte cultures. Entecavir was not mutagenic in the Ames bacterial reverse mutation assay using and strains in the presence or absence of metabolic activation, a mammalian-cell gene mutation assay, and a transformation assay with Syrian hamster embryo cells. Entecavir was also negative in an oral micronucleus study and an oral DNA repair study in rats.
  • Impairment of Fertility
  • In reproductive toxicology studies, in which animals were administered entecavir at up to 30 mg/kg for up to 4 weeks, no evidence of impaired fertility was seen in male or female rats at systemic exposures greater than 90 times those achieved in humans at the highest recommended dose of 1 mg/day. In rodent and dog toxicology studies, seminiferous tubular degeneration was observed at exposures 35 times or greater than those achieved in humans. No testicular changes were evident in monkeys.

  • See FDA-approved patient labeling (Patient Information).
  • Severe Acute Exacerbation of Hepatitis after Discontinuation of Treatment
  • Inform patients that discontinuation of anti-hepatitis B therapy, including entecavir, may result in severe acute exacerbations of hepatitis B. Advise the patient to not discontinue entecavir without first informing their healthcare provider .
  • Risk of Development of HIV-1 Resistance in Patients with HIV-1 Coinfection
  • Inform patients that if they have or develop HIV infection and are not receiving effective HIV treatment, entecavir may increase the risk of development of resistance to HIV medication .
  • Lactic Acidosis and Severe Hepatomegaly
  • Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with use of drugs similar to entecavir. Advise patients to contact their healthcare provider immediately and stop entecavir if they develop clinical symptoms suggestive of lactic acidosis or pronounced hepatotoxicity n
  • Missed Dosage
  • Inform patients that it is important to take entecavir on a regular dosing schedule on an empty stomach (at least 2 hours after a meal and 2 hours before the next meal) and to avoid missing doses as it can result in development of resistance n
