I'd definitely ask about the trial and let us know which one it is. Is this a trial to monitor how he handles stopping medication for a few months? I know there was research on this. Or is it a cure trial and in order for him to qualify, they need his levels to rise? I don't think there is any cure trial that does this but I could be wrong. Usually all they care about is whether you have been diagnosed as Hepatitis B positive within the past 6 months... but I could be wrong here as well. Personally, I would not risk this unless it was a guarantee cure but you put yourself in a bad situation with liver damage already this way.
