Abbott Introduces Hepatitis B Sequencing Test in Europe

WIESBADEN, Germany, March 31, 2011 /PRNewswire/ -- Abbott Molecular announced

today that it has received CE Marking (Conformite Europeene) to market the

Abbott HBV Sequencing test in the European Union. This molecular diagnostic

test, developed to identify genomic sequences of the hepatitis B virus (HBV) and

help physicians monitor HBV infections, guide treatment decisions, and predict

or discover drug resistance, is the first DNA sequencing assay developed and

introduced by Abbott Molecular.

The CE-Marked Abbott HBV Sequencing test identifies the DNA sequence of the HBV

polymerase gene including all clinically relevant HBV drug resistant mutations.

The test is not intended for screening blood donors, plasma or tissue donors for

HBV, or to be used as a diagnostic test to confirm the presence of HBV

infection.

HBV is classified into eight separate genotypes (labeled A-H). HBV genotype is a

prognostic indicator because it correlates with disease severity and response to

interferon therapy. For example, genotype C is prevalent in Asia and associated

with more severe liver disease and development of liver cancer. In contrast,

genotype B (also prevalent in Asia) has a better prognosis and is rarely

associated with progression to liver cancer. Also, patients with HBV genotypes A

and B seem to respond better to interferon therapy than those with genotypes C

and D.

Significant progress has occurred in recent years in developing antiviral

therapies for HBV. Several anti-polymerase drugs are available worldwide. The

new HBV Sequencing assay can be used in tandem with Abbott's RealTime HBV viral

load assay to monitor the efficacy of HBV treatments.

" The addition of the Abbott HBV Sequencing assay offers laboratories a highly

precise method for managing HBV patients. After assessing patient viral loads,

physicians can order the HBV Sequencing test to select or change antiviral

therapies based on known drug resistance of specific viral genotypes, " said

a Rodnikova, divisional vice president and general manager of Abbott's

molecular diagnostics business in Europe.

" The Abbott RealTime HBV viral load and HBV Sequencing assays are examples of

how molecular diagnostic technologies are helping clinicians worldwide manage

serious infectious diseases more precisely and effectively through optimal

utilization of antiviral drugs. "

The Abbott HBV Sequencing assay was developed for use on the Life Technologies

ABI 3130 DNA sequencing system.

About Hepatitis B

A serious global public health problem, hepatitis B is an inflammatory liver

disease caused by the hepatitis B virus that results in liver cell damage. The

damage can lead to scarring of the liver (cirrhosis) and increased risk of liver

cancer.

Hepatitis B is preventable with safe and effective vaccines that have been

available since 1982, according to the World Health Organization (WHO). But

today some two billion people have been infected with the hepatitis B virus, and

more than 350 million are chronic carriers. In countries with a high prevalence

of chronic HBV infection, the most common route of infection is from mother to

child at birth or from young children infecting each other. In areas of low

prevalence, HBV usually is transmitted during adulthood from intravenous drug

use or high-risk sexual activity.

Ninety-five percent of adults infected with HBV develop antibodies and recover

within six months. Upon recovery, they develop immunity to the virus and are not

infectious to others. Those with chronic HBV infections are at high risk for

cirrhosis of the liver and liver cancer, which account for about one million

deaths every year.

About Abbott Molecular

Abbott Molecular, abbottmolecular.com, is an emerging leader in molecular

diagnostics — the analysis of DNA, RNA, and proteins at the molecular level.

Some of Abbott Molecular's tests are designed to detect subtle but key changes

in human genes and chromosomes. The results of these tests may aid in the

earlier detection or diagnosis of disease, may influence the selection of

appropriate therapies, and may improve monitoring of disease progression.

About Abbott

Abbott (NYSE: ABT) is a global, broad-based health care company devoted to the

discovery, development, manufacture and marketing of pharmaceuticals and medical

products, including nutritionals, devices and diagnostics. The company employs

nearly 90,000 people and markets its products in more than 130 countries.
