Abstract

Phase 3 clinical studies have shown that long-term treatment with tenofovir disoproxil fumarate (TDF) can suppress hepatitis B viral load and promote significant fibrosis regression and cirrhosis reversal in a majority of treated chronic hepatitis B (CHB) patients. This retrospective analysis investigated the impact of baseline cirrhosis status on virologic, serologic, and histologic outcomes in patients treated with TDF. Patients enrolled in studies GS-US-174-0102 and GS-US-174-0103 who had baseline liver biopsy-diagnosed cirrhosis and entered the open-label phase of the studies were included in the virologic and serologic analyses. Patients (both HBeAg positive and negative) with paired liver biopsies at baseline and 5 years (N = 348) were included in a histologic analysis. After 5 years on study, comparing patients with and without baseline cirrhosis, respectively: 99.2 and 98.0% achieved virologic response (hepatitis B viral load < 69 IU/ml) (p = 0.686); 79.7 and 81.9% had normal serum levels of alanine aminotransferase (p = 0.586); 4.0 and 1.2% developed hepatocellular carcinoma (p = 0.044). In HBeAg-positive patients with and without baseline cirrhosis, HBsAg loss occurred in 14.4 and 8.3% of patients, respectively (p = 0...Continue Reading
