TVR(vx950) is in Phase 2, will be available in a few years, and for now it is the best drug candidate for the type of HCV you have. However, TVR has to be taken along with interferon and ribavirin to show its efficacy for now. The chance of getting rid of your virus is as high as 60% and as low as 40% when the above triple combination is used against your strand because you have already gone through Ifn and Rbv. You may have to wait longer than 3 years if you don't want to take Rbv again. Better drugs and drug combinations will come along in future.
