Undesirable effects Entecavir Cristers

Summary of the job security profile

In clinical studies in patients with compensated liver disease, the most common adverse effects, regardless of severity, with at least one causal relationship to entecavir, are headache (9%), fatigue (6%), dizziness (4%) and nausea (3%). Exacerbations of hepatitis during and after stopping treatment with entecavir have also been reported (see Warnings and Precautions and (c) Description of Specific Adverse Reactions).

Summary table of adverse effects


The adverse reaction assessment is based on the experience gained since the drug's launch and four clinical trials in which 1, 720 patients with chronic hepatitis B infection and compensated liver disease received double-blind treatment with entecavir (n = 862) or lamivudine (n = 858) for up to 107 weeks (see section 5.1 ). In these studies, safety profiles, including laboratory abnormalities, were comparable for entecavir 0.5 mg once daily (679 HBeAg positive or negative patients who had never received treatment with a nucleoside analogue, treated with average duration of 53 weeks), entecavir 1 mg once daily (183 lamivudine-resistant patients treated for an average of 69 weeks) and lamivudine.

Adverse reactions considered to be attributable to treatment with entecavir are listed below by organ class. Frequency is defined as: very common (≥ 1/10); frequent (≥ 1/100 to <1/10); uncommon (≥ 1 / 1, 000 to <1/100); rare (≥ 1 / 10, 000 to <1 / 1, 000). Within each group frequency, adverse effects should be presented in order of decreasing severity.

Immune system disorders

rare: anaphylactoid reaction

Psychiatric disorders

frequent: insomnia

Nervous system disorders

frequent: headache, dizziness, drowsiness

Gastrointestinal disorders

frequent: vomiting, diarrhea, nausea, dyspepsia

Hepatobiliary disorders

frequent: increased transaminases

Skin and subcutaneous tissue disorders

uncommon: rash, alopecia

General disorders and administration site conditions

frequent: tiredness

Cases of lactic acidosis have been reported, often in association with hepatic decompensation, other serious medical conditions or drug exposures (see Warnings and Precautions section ).

Treatment beyond 48 weeks: continuous treatment with entecavir for an average of 96 weeks did not show any changes in the safety profile of entecavir.

Description of selected adverse effects Biological abnormalities

In clinical trials in patients who have never received treatment with a nucleoside analogue, 5% of patients had an elevation of ALT> 3 times baseline, and 2 times baseline with total bilirubin> 2 times the upper limit of normal (ULN) and> 2 times the initial level. Albumin levels <2.5 g / dl occurred at 3 times baseline, 11% lipase> 3 times baseline, and <1% of patients had platelet counts <50, 000 / mm³.

In clinical trials in lamivudine-resistant patients, 4% of patients had an elevation of ALT> 3 times the baseline, and twice the baseline with total bilirubin> 2 times ULN and> 2 times the baseline. initial level. 2% of patients had amylasemia> 3 times baseline, 18% had lipase> 3 times baseline, and <1% had platelet counts <50, 000 / mm3

Exacerbations during treatment

In studies in patients who have never received treatment with a nucleoside analogue, an increase in ALT under treatment> 10 times ULN and> 2 times the baseline was observed in 2% of patients treated with entecavir versus 4% of patients treated with lamivudine. In studies with lamivudine-resistant patients, an elevation of ALT under treatment> 10 times ULN and> 2

the baseline was observed in 2% of patients treated with entecavir versus 11% of patients treated with lamivudine. Among the patients treated with entecavir, an elevation of ALT under treatment was observed after a mean time of 4-5 weeks and generally gave way with the continuation of treatment, and in most cases this elevation has been associated with a reduction in viral load ≥ 2 log 10 / ml, before or at the same time as the increase in ALAT. Periodic control of liver function is recommended during treatment.

Exacerbations after stopping treatment

Acute exacerbations of hepatitis have been reported in patients who discontinued anti-hepatitis B therapy, including treatment with entecavir (see Warnings and Precautions ). In studies in nucleoside-naive patients, 6% of entecavir-treated patients and 10% of lamivudine-treated patients experienced elevations of ALT (> 10-fold ULN and> 2-fold baseline [minimum value between the initial value and the value of the latest biological analyzes]) during post-treatment follow-up. Among the nucleoside-naive patients treated with entecavir, ALT elevations occurred on average 23 to 24 weeks after discontinuation of therapy, and 86% (24/28) of these ALT elevations occurred in HBeAg patients. negative. In studies in lamivudine-resistant patients, with a limited number of patients being followed, 11% of patients treated with entecavir and none of the lamivudine-treated patients developed an increase in ALT during post-treatment follow-up.

In clinical studies, treatment with entecavir has been discontinued in patients achieving a predefined response. If treatment is stopped for any reason other than a response to treatment, the frequency of ALT increases after treatment may be higher.

Pediatric population

The safety of entecavir in pediatric patients aged 2 years to less than 18 years old is based on two ongoing clinical studies in subjects with chronic HBV infection: a Phase 2 pharmacokinetic study (Study 028). ) and a Phase 3 study (Study 189). These studies provide data from 195 Ag-HBe positive, nucleoside-treatment-naive subjects treated with entecavir over a median of 99 weeks. Adverse events observed in pediatric patients treated with entecavir are consistent with those observed in adult entecavir clinical studies (see Safety Summary Summary and Pharmacodynamic Properties section). ).

Other special populations

Data in patients with decompensated liver disease

The safety profile in patients with decompensated liver disease was evaluated in a randomized, open-label comparative study in patients receiving entecavir 1 mg / day (n = 102) or Adefovir dipivoxil 10 mg / day (n = 89) (Study 048). Regarding the side effects listed in section b. Summary table of adverse events, an additional adverse effect [decreased blood bicarbonate levels (2%)] was observed in patients treated with entecavir for 48 weeks. The cumulative mortality rate in the study was 23% (23/102) and the causes of death were generally related to liver function, as expected in this patient population. The cumulative rate of hepatocellular carcinoma (HCC) in the study was 12% (12/102). Serious adverse events were generally related to the liver with a cumulative frequency during the study of 69%. Patients with a high CPT score at baseline were at higher risk of developing serious adverse events (see Warnings and Precautions section ).

Biological abnormalities

At 48 weeks, among patients treated with entecavir and with decompensated liver disease, none had elevations of ALT at both> 10-fold ULN and> 2-fold baseline, and 1 per cent of patients had elevations of 'ALAT> 2 times baseline with total bilirubin> 2 times ULN and> 2 times baseline. Albumin levels 3 times the initial level in 10% and platelets <50, 000 / mm³ in 20%.

Data in patients co-infected with HIV

The safety profile of entecavir in a limited number of patients co-infected with HIV and HBV under HAART (Highly Active Antiretroviral Therapy) containing lamivudine was similar to the safety profile of patients monoinfected with HBV (see section Warnings and precautions for use ).

Age / sex

There was no difference in entecavir safety profile by sex (≈ 25% of women in clinical trials) or age (≈ 5% of patients were> 65 years of age).

Reporting of suspected adverse reactions

The reporting of suspected adverse reactions after authorization of the drug is important. It allows continuous monitoring of the benefit / risk ratio of the drug. Health professionals declare any suspected adverse reaction via the national reporting system: National Agency for the Safety of Medicines and Health Products (ANSM) and the network of Regional Pharmacovigilance Centers - Website: www.ansm.sante.fr.
