BACKGROUND: Sofosbuvir and ledipasvir, which have recently been approved for
treatment of chronic hepatitis C virus (HCV) infection, are more efficacious and
safer than the old standard of care (oSOC) but are substantially more expensive.
Whether and in which patients their improved efficacy justifies their increased
cost is unclear. OBJECTIVE: To evaluate the cost-effectiveness and budget impact
of sofosbuvir and ledipasvir. DESIGN: Microsimulation model of the natural
history of HCV infection. DATA SOURCES: Published literature. TARGET POPULATION:
Treatment-naive and treatment-experienced HCV population defined on the basis of
HCV genotype, age, and fibrosis distribution in the United States. TIME HORIZON:
Lifetime. PERSPECTIVE: Third-party payer. INTERVENTION: Simulation of
sofosbuvir-ledipasvir compared with the oSOC (interferon-based therapies).
OUTCOME MEASURES: Quality-adjusted life-years (QALYs), incremental
cost-effectiveness ratios (ICERs), and 5-year spending on antiviral drugs.
RESULTS OF BASE-CASE ANALYSIS: Sofosbuvir-based therapies added 0.56 QALY
relative to the oSOC at an ICER of $55 400 per additional QALY. The ICERs ranged
from $9700 to $284 300 per QALY depending on the patient's status with respect to
treatment history, HCV genotype, and presence of cirrhosis. At a
willingness-to-pay threshold of $100 000 per QALY, sofosbuvir-based therapies
were cost-effective in 83% of treatment-naive and 81% of treatment-experienced
patients. Compared with the oSOC, treating eligible HCV-infected persons in the
United States with the new drugs would cost an additional $65 billion in the next
5 years, whereas the resulting cost offsets would be $16 billion. RESULTS OF
SENSITIVITY ANALYSIS: Results were sensitive to drug price, drug efficacy, and
quality of life after successful treatment. LIMITATION: Data on real-world
effectiveness of new antivirals are lacking. CONCLUSION: Treatment of HCV is
cost-effective in most patients, but additional resources and value-based patient
prioritization are needed to manage patients with HCV. PRIMARY FUNDING SOURCE:
