ROBERT GREENBERG, MD: The results for the biologic agents seem to improve the longer the patient is receiving the medication. The initial responses are what the majority of the studies have been done on, but the longer the patient seems to be treated with these medicines, the responses seem to get better over time.
ANNOUNCER: Biologic treatment involves brief injections, but how they're given, for how long, and what patients can expect will differ.
PAUL YAMAUCHI, MD: The patient who receives Amevive comes to the doctor's office once a week to get a shot in the muscle. So patients on Amevive receive a twelve-week course once a week and then they are off of it for a minimum of twelve weeks before the doctor decides whether they receive another twelve-week course.
We've had quite a few patients who have received Amevive and, after one course, got a pretty good response. But with this drug, when you're off of it, the psoriasis continues to improve, which we saw in our patients. But when patients received a second or a third course of Amevive, the results were more dramatic. The more courses of Amevive they receive, the better response rate, the better the longer the remission.
ROBERT GREENBERG, MD: Raptiva is a medicine that is given on a weekly injection by the patient at home. Raptiva is given on an ongoing basis by the patient. Raptiva is not stopped while they're responding to the therapy.
