Chronic infection with hepatitis B virus (HBV) causes liver disease and cirrhosis. It is not clear how treatment of chronic HBV infection affects patient-reported outcomes (PROs). We aimed to assess changes in PROs in patients treated for chronic HBV infection.We collected and analyzed PRO data from 242 patients with chronic HBV infection (without advanced fibrosis or cirrhosis) enrolled in 2 international phase 2 blinded controlled clinical trials from 2015 through 2017. In these trials, patients were treated with an approved oral antiviral regimen (tenofovir, entecavir, adefovir, lamivudine, or telbivudine) and then randomly assigned to groups given vesatolimod (an oral agonist of toll like receptor 7) or placebo. PROs were collected using the Short Form-36, the Chronic Liver Disease Questionnaire, and the Work Productivity and Activity Impairment: Specific Health Problem scoring system before treatment, on treatment weeks 12, 24, and 48.We did not observe significant differences in PROs between patients receiving vesatolimod vs placebo. At baseline, patients with viral suppression (level of HBV DNA <20 IU/mL) had higher PRO scores (by up to +10.6% of a PRO range size). During treatment, there were significant increases in scores for some domains of Chronic Liver Disease Questionnaire and in General Health scores of Short Form-36 (increases of up to 4.9%; P<.05). Patients with a decrease of at least 2.7 log10IU/mL in level of HBV DNA had substantially larger increases in PRO scores (mean increases of up to 7.2% by week 48; P<.05 for 10 of 22 studied PROs). In multivariate analysis, a reduction in viral load was independently associated with increases in PROs (betas values up to 1.6% per log10IU/mL decrease; P<.05).In an analysis of data from phase 2 trials, we associated active treatment of chronic HBV infection with increased PRO scores. These findings support inclusion of PRO endpoints in assessments of efficacy and safety in clinical trials of treatments for HBV infection.
