Q2. Correct Answer: D
Elbasvir and grazoprevir are hepaticaly metabo¬lized and undergo minimal renal elimination making them safe for use in patients with end stage renal disease. The C-Surfer trial evaluated elbasvir and grazoprevir in genotype 1 patients with advanced renal disease inclusive of patients on hemodialysis. Cure rates in this trial were 94- 99 percent. Sofosbuvir containing regimen are not approved for patient with CKD stage 4-5 or those on hemodialysis, even when given in a dose reduced or post-dialysis fashion.
