other than peg-intron, are there any other more recent treatments that offer higher sustainable remission rates for a person with Genotype 1A who quickly becomes negative following 3-6 mos of therapy; remains on therapy for total of 12 mos, with weight based dosing of peg intron, but relapses within 3-6 months of ending therapy? is a lower ongoing maintenance dosing appropriate to sustain remission after 12 mos of therapy?

There are two brands of pegylated interferon, the peg intron that you mention and the pegasys brand. They are very similar. I usually switch brands when re treating. However our team usually treats the relapsers longer than 12 months often for 18 months. We think that will help prevent relapse. DTD
