Successful prolonged treatment with sofosbuvir/velpatasvir for a hepatitis C patient with decompensated cirrhosis and treatment failure after 12-week therapy.

ABSTRACT

There is no established rescue therapy for hepatitis C patients with decompensated cirrhosis who experience treatment failure on 12-week sofosbuvir (SOF)/velpatasvir (VEL) therapy that is the only approved regimen for decompensated cirrhosis in Japan. We experienced a patient with decompensated cirrhosis who showed virologic relapse at post-treatment week 7 following 12-week SOF/VEL therapy. She had resistance-associated substitutions (RASs) against VEL before therapy but did not achieve new RASs against VEL or SOF after therapy. We considered rescue therapy following strong demand from her and her family. The drug adherence of therapy was 100%, and the treatment was well tolerated. Because we prioritized the safety and drug adherence of the regimen, we performed prolonged 24-week SOF/VEL therapy without ribavirin at her own expense with the approval of the ethics board in the hospital where the first author belongs. Fortunately, a sustained virologic response 24 was achieved without any adverse events. Hepatocellular carcinoma that had developed after 12-week SOF/VEL therapy recurred and was treated near the end of rescue therapy, but hepatic functional reserve improved. Although this was a single case report and was assumed to be very rare, the same regimen might be effective for treatment failure with 12-week SOF/VEL therapy.
