Bristol-Myers
Squibb Company (NYSE: BMY) today announced data from a cohort of
nucleoside-naive HBeAg-negative chronic hepatitis B patients (ETV-027/901,
n=99). These data showed that patients who experienced recurrent levels of
hepatitis B virus in the blood after interruption of treatment with
BARACLUDE(R) (entecavir) achieved viral suppression and liver enzyme (ALT)
normalization when re- treated for 48 weeks with BARACLUDE. The study
results were presented at the 42nd Annual Meeting of the European
Association for the Study of Liver Diseases (EASL) in Barcelona, Spain.
In this cohort, 93 percent of patients who were re-treated with
BARACLUDE had undetectable viral load - the level of the hepatitis B virus
in the blood - (HBV DNA
The analysis cohort was defined regardless of treatment response at the
end of dosing in study ETV-027, and independent of virologic or ALT
measurements at the start of dosing in study ETV-901. During off-treatment
follow-up, the majority of patients had recurrent levels of hepatitis B
virus in the blood (viremia) and increases in ALT.
Data Results
At the end of dosing for study ETV-027:
-- 94 percent (n=93/99) of the re-treatment cohort had undetectable viral
load
-- 78 percent (n=77/99) had ALT normalization
At entry into ETV-901:
-- Four percent (n=4/99) of patients had undetectable viral load
-- Eight percent (n=8/97) of patients had ALT normalization
Following re-treatment in study ETV-901:
-- 93 percent (n=82/88) of patients had undetectable viral load (HBV DNA
2 times baseline and >10 times the upper level of normal)
About BARACLUDE(R) (entecavir)
Discovered at Bristol-Myers Squibb, BARACLUDE(R) (entecavir) is a
nucleoside analogue indicated for the treatment of chronic hepatitis B
virus infection in adults with evidence of active viral replication with
either evidence of persistent elevations in serum aminotransferases (ALT or
AST) or histologically active disease. BARACLUDE has been approved in more
than 60 countries and regions around the world.
Important Information About BARACLUDE(R) (entecavir) 0.5mg/1mg Tablets
BARACLUDE(R) (entecavir) is a prescription medicine used for chronic
infection with hepatitis B virus (HBV) in adults where the virus is
multiplying and damaging the liver. BARACLUDE does not cure HBV or stop the
spread of HBV to others.
People should not take BARACLUDE if they are allergic to it or any of
its ingredients. BARACLUDE has not been studied in children and is not
recommended for anyone less than 16 years of age.
People taking BARACLUDE(R) (entecavir) should tell their healthcare
provider right away if they feel very weak or tired, have unusual muscle
pain, have trouble breathing, have stomach pain with nausea and vomiting,
feel cold - especially in their arms and legs, feel dizzy or lightheaded,
or have a fast or irregular heartbeat, as they may be signs of a serious
condition called lactic acidosis (buildup of an acid in the blood).
Lactic acidosis is a medical emergency and must be treated in the
hospital. Some people who have taken medicines like BARACLUDE have
developed serious liver problems called hepatotoxicity. This may occur with
liver enlargement (hepatomegaly) and fat in the liver (steatosis).
People should call their healthcare provider right away if they get any
of the following signs of liver problems: yellowing (jaundice) of the skin
or the white part of the eyes, darkening of the urine, lightening in the
color of bowel movements (stools), not feeling like eating food for several
days or longer, feeling sick to the stomach (nausea), or having lower
stomach pain. Lactic acidosis and hepatotoxicity have happened in some
people taking medicines like BARACLUDE.
In some people, hepatitis B symptoms may get worse or become very
serious when they stop taking BARACLUDE. People should not stop BARACLUDE
without talking to their healthcare provider. Healthcare providers will
need to follow their patients and do blood tests to check the liver when
BARACLUDE is stopped. People should tell their healthcare provider if they
have or develop kidney problems because their healthcare provider may want
to do tests to see if a lower dose is needed or a different dose schedule.
Because BARACLUDE is removed from the body through the kidneys, a lower
dose or a different dose schedule may be required. Healthcare providers may
want to perform tests to determine whether a patient needs a lower dose or
should take BARACLUDE less often than once a day.
It is not known if BARACLUDE is safe to use during pregnancy. It is not
known if BARACLUDE helps to prevent a pregnant mother from passing HBV to
her baby. A pregnant woman and her healthcare provider will need to decide
if BARACLUDE is right for her. A woman should not breastfeed if she is
taking BARACLUDE.
People should discuss with their healthcare provider all prescription
and non-prescription medicines, vitamins, herbal supplements, and other
health preparations they are taking or plan to take. BARACLUDE(R)
(entecavir) may interact with medicines that leave the body through the
kidneys. The most common side effects of BARACLUDE in clinical studies were
headache, tiredness, dizziness, and nausea.
This list of side effects is not complete at this time because
BARACLUDE is still under study. People should report any new or continuing
symptom to their healthcare provider. BARACLUDE should be taken once daily
on an empty stomach (at least two hours after a meal and two hours before
the next meal). To learn more about BARACLUDE and for Full Prescribing
