The price tag of a potential cure for chronic hepatitis B infection: A cost threshold analysis for USA, China and Australia.

We show that in purely economic terms, a CHB cure will be highly cost-effective even if effective in only 30% of treated patients. The threshold price for cure is largely determined by the current antiviral drug costs, since it will replace a daily antiviral pill that is inexpensive and effective, although not curative. The likely need for combination therapies to achieve cure will also present cost challenges. While cost-effectiveness is important, it cannot be the only consideration, as cure will provide many benefits in addition to reduced liver disease and HCC, including eliminating the need for a long-term daily pill and reducing stigma often associated with chronic viral infection.
