| In 2005, 
                  the US Food and Drug Administration (FDA) approved PEGASYS for 
                  the treatment of chronic hepatitis B. Already the most prescribed 
                  hepatitis C medication in the United States, PEGASYS is the 
                  first and only pegylated interferon 
                  approved for the treatment of chronic hepatitis B, including 
                  both main types of the virus. PEGASYS 
                    helps in two important ways:  
                    - PEGASYS 
                      slows replication of the hepatitis B virus. - PEGASYS boosts the body's immune system.
