i) Obtain preliminary information on the association between important baseline and on-treatment factors and SVR in this patient population. Variables to be examined may include gender, age, advanced fibrosis or cirrhosis (F3 or F4 estimated by Fibroscan), baseline viral load, RVR, wk 8 viral load, end-of-treatment viral response.

ii) Evaluate adverse events. iii) Evaluate viral resistance.
