Which Hep C Treatments Are The Most Cost-Effective?
Newer hepatitis C (HCV) regimens have shorter treatment periods and increased rates of sustained viralogic response compared to the existing therapies, but are much more expensive.
In order to evaluate the cost-effectiveness of these treatments, researchers conducted a review examining treatment-naïve participants with chronic HCV genotype 1, 2, and 3.

“Usual care (boceprevir–ribavirin–pegylated interferon [PEG]) was compared with sofosbuvir–ribavirin–PEG and 3 PEG-free regimens: sofosbuvir–simeprevir, sofosbuvir–daclatasvir, and sofosbuvir–ledipasvir,” said the study’s researchers.
“For genotypes 2 and 3, usual care (ribavirin–PEG) was compared with sofosbuvir–ribavirin, sofosbuvir–daclatasvir, and sofosbuvir–ledipasvir–ribavirin (genotype 3 only),” they said.
Assuming that sofosbuvir, simeprevir, daclastasvir, and ledipasvir cost $7000, $5500, $5500, and $875, respectively, researchers found that sofosbuvir-ledipasvir appeared to be the most cost-effective for genotype 1. The drugs cost $12,825 more per quality-adjusted life-years (QALY) compared to usual care.
For genotype 2, sofosbuvir-ribavirin cost $110,000 and sofosbuvir-daclatasvir cost $691,000 per QALY.
Further, sofosbuvir-ledipasvir-ribavirin cost $73,000 per QALY, sofosbuvir-declastasvir cost over $396,000 per QALY at assumed prices, and sofosbuvir-ribavirin was more expensive and less effective than usual care for genotype 3.
The researchers discovered that sofobuvir-ledipasvir was the optimal strategy for genotype 1 and would be cost-effective if the drug cost less than $5500.
For genotype 2, sofosbuvir-ribavirin-PEG would be cost-efficient if sofobuvir cost less than $2250 every week, and sofosbuvir-ledipasvir-ribavirin would be the most cost-saving for genotype 3 if sofosbuvir cost less than $1500 per week.
