ABSTRACT

BACKGROUND: In China, the optimal management of individuals living with chronic HBV infection (CHB) remains an unmet need. The EVOLVE Study was a 5-year prospective, longitudinal, observational study that compared the clinical outcomes in treatment-naive CHB patients receiving entecavir (ETV) or lamivudine (LAM)-based therapies. METHODS: Males or females aged ≥18 years, diagnosed with CHB regardless of cirrhosis or hepatitis B e antigen (HBeAg) status were enrolled from tier 2 city hospitals (between 2012-2014). The choice of initial therapy and subsequent treatment modifications was at the discretion of treating physicians. Key outcomes included treatment modifications, virological response (HBV DNA <300 copies/ml) and HBV disease progression. RESULTS: Of the 3,408 patients enrolled, 1,807 and 628 received ETV and LAM-based therapy, respectively. The mean age was 39.5 years, 74% were male and 22.9% had cirrhosis. The rate of treatment modification was higher in the LAM-based versus ETV group (25.9% versus 13.7%); viral breakthrough was the most common reason in the LAM-based group versus financial reasons in the ETV group. At week 240, the virological response rate was 73% in both treatment groups. Compared with LAM-based therapy, ETV was associated with a significantly lower incidence of viral breakthrough (12.6% versus 2.1%) and genotypic resistance (10.1% versus 1.2%; P<0.0001 for both); significantly lower risk of HBV disease progression (14.0% versus 10.7%; P=0.0113); and lower rates of progression to decompensated cirrhosis (9.6% versus 6.4%) and hepatocellular carcinoma (1.9% versus 0.8%). CONCLUSIONS: This real-world, longitudinal study demonstrated a significantly lower risk of HBV-related disease progression, viral breakthrough and resistance with ETV versus LAM-based therapy. ClinicalTrials.gov NCT01726439.

ABSTRACT

BACKGROUND: This 5-year follow-up of the CCgenos cross-sectional study aimed to observe real-life outcomes in a cohort of 997 Han Chinese patients with chronic HCV infection and to explore the impacts of HCV genotype, patient characteristics and treatment status. METHODS: Clinical information and centralized HCV RNA measures were collected every 6/3 months for untreated/treated patients. Overall disease progression was defined as ≥1 of: de novo development of cirrhosis, Child-Turcotte-Pugh score increased by ≥2 points (if cirrhosis at baseline), progression to decompensated cirrhosis, hepatocellular carcinoma (HCC), liver transplant or death. Cox regression assessed risk factors for the time from estimated infection to cirrhosis or HCC. Logistic regression assessed risk factors for incidence rates of cirrhosis and overall disease progression. RESULTS: 281 of 514 patients enrolled across China completed 5 years of follow-up. Overall disease progression occurred in 36/364 (9.9%) treated patients and 35/148 (23.6%) untreated patients (odds ratio = 0.35; 95% CI 0.21, 0.59; P<0.0001). Overall disease progression occurred in 6/231 (2.6%) patients achieving sustained virological response at 24 weeks (SVR24) versus 11/82 (13.4%) who did not (P=0.0002). Cirrhosis development was significantly associated with abnormal aspartate aminotransferase (AST), age ≥40 years, body mass index ≥28 kg/m2, HCV GT1, platelet count <100×109/l, and AST to platelet ratio index (APRI) ≥2 (multivariate Cox regression, P<0.05). HCC was significantly associated with HCV GT1 and platelet count <100×109/l (multivariate Cox regression, P<0.05). CONCLUSIONS: Achieving SVR24 significantly reduced the probability of overall disease progression but no significant difference was seen for both cirrhosis and HCC during 5 years of follow-up.
