“Sometimes I’m blocked by insurance companies because this isn’t officially approved,” noted Dr. Flamm, professor of medicine and chief of the hepatology program at Northwestern University, Chicago.
“You’re right,” Dr. Terrault commented, “we have to make a pretty compelling argument to the insurer as to why we’re treating. But ‘treat to prevent transmission to others’ usually is successful in our hands.”
HCV in patients with end-stage renal disease
The product labeling for sofosbuvir (Sovaldi) says the drug’s safety and efficacy haven’t been established in patients with severe renal impairment or end-stage renal disease. However, a small multicenterpresented at the 2017 AASLD meeting demonstrated that 12 weeks of ledipasvir/sofosbuvir achieved a 100% SVR rate in patients with genotype 1 HCV and severe renal impairment, including some on dialysis, with no clinically meaningful change in estimated glomerular filtration rate or any signal of cardiac arrhythmia.
“The serum drug levels went up significantly, but reassuringly they saw no meaningful safety signals,” according to Dr. Terrault. “This, I think, is initial reassuring information that we were all very much waiting for.”
