Avastin and Herceptin

Hi,
Is anybody taking part in the herceptin and avastin trial? I would like to know how you are responding and if there are any side effects to it? Did the doc inform you of any of the likely side effects? I understand that it is a monoclonal antibody which causes the blood vessels to shrink and there by cutting off vital supply to the tumor cells. I would appreciate any response from anyone who is enrolled in this trial. Thank you
