Thanks dewophile, and gofishmarko, for your views.
i forwarded the questions and suggestions to my sister who will meet with Dr. Schiff sometime next week. my mother is tx refractory gen 1 and she has been on all the drugs approved to treat her hcv. i rememeber before some of the drugs were approved here in the states we used to get them from mexico for her. she is now over seventy and i have noticed that sometimes these studies exclude patients over certain ages, i have to believe that her doctors Schiff and Jeffers had thought of her for the trial and there may have been a disqualifying factor, but we will know more next week.
thanks for the helpful ideas.
