The indication is in adults with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (ALT or AST) or histologically active disease.
Entecavir is an oral antiviral therapy specifically designed to block the replication of hepatitis B virus (HBV) in the liver.
The drug will be available in the Philippines in the first quarter.
Chronic hepatitis B infection is a potentially life-threatening disease. More than half a million people worldwide die each year from primary liver cancer (hepatocellular carcinoma), and up to 80 percent of primary liver cancers are caused by chronic hepatitis B.
In the Philippines, the prevalence rate of chronic hepatitis B ranges from five to 16 percent, placing the country in the intermediate to high endemic region.
More than half or 59 percent of the Filipino patients with cirrhosis and 82 percent of patients with liver cancer have had hepatitis B infection.
Primary liver cancer is the most common gastrointestinal cancer and third most common cancer in the Philippines.
"With the approval of entecavir in the Philippines, Bristol-Myers Squibb will now be able to address another area of significant unmet medical need: hepatitis B," said David Elsaputra, general manager of Bristol-Myers Squibb Philippines Inc.
"Developed in our own laboratories, entecavir is an important step forward for patients and our company, as we seek to realize our mission of extending and enhancing human life by focusing on discovering, developing and providing innovative treatments for serious diseases," he said.
According to the Asian-Pacific consensus statement on the management of chronic hepatitis B (2005 update), sustained viral suppression is the key to reduction or prevention of hepatic injury and disease progression, and that the primary goal of treatment for chronic hepatitis B is to eliminate or permanently suppress the hepatitis B viral load.
The viral load is a key predictor of progression to serious liver disease and hepatocellular carcinoma (HCC or liver cancer). The higher the viral load, the greater the risk of developing cirrhosis and HCC.
With the approval of entecavir, physicians have an important new medication to treat chronic hepatitis B by reducing the viral load and the associated risk of developing cirrhosis and liver cancer.
Discovered at Bristol-Myers Squibb, entecavir is a nucleoside analog approved for marketing in the United States by the US Food and Drug Administration (FDA) on March 29, 2005.
To date, entecavir has also been approved in several countries, including China, Macau and Indonesia.
Bristol-Myers Squibb has submitted marketing applications for entecavir in other regions and countries, including Taiwan, Korea and Hong Kong.
