Program Abstract
Background and aims: IFN causes substantial impairment of QoL. We compared PROs and QoL between IFN-free and IFN-containing-SOF regimens.
Methods: 525 patients receiving IFN+RBV+SOF (NEUTRINO) or RBV+SOF (FUSION) completed PRO questionnaires: CLDQ-HCV (QoL), FACIT-F (Fatigue) and WPAI-SHP (work productivity and activity). Subjects were blinded to virologic data.
Results: Baseline depression/anxiety, insomnia and fatigue were similar between IFN-free or IFN-containing regimens (p>0.05). By the end-of-treatment, decrements in PRO scores were higher in those receiving IFN-regimen: physical well-being (decrement=18.9% IFN-based vs. 4.6% IFN-free, p< 0.0001), functional well-being (13.2% vs. 6.1%, p=0.0002), fatigue (19.4% vs. 2.7%, p< 0.0001), total-FACIT-F (12.2% vs. 2.4%, p< 0.0001), all domains of CLDQ-HCV (9.5% to 19.3% vs. 0.3% to -3.3%, p< 0.05), work productivity (23.2% vs. 5.7%, p=0.004) and activity impairment (22.2% vs. 6.5%, p=0.002). In multivariate analysis, predictors of poor PROs at baseline were depression (beta=-9.4 to -13.6%, p< 0.05) and fatigue (beta=-12.2 to -22.5%, p< 0.05). At the end-of-treatment, predictors of poor PROs included receiving IFN (beta=-4.7 to -13.2%, p< 0.05), depression (beta=-6.4 to -6.5%, p< 0.05), fatigue (beta=-10.9 to -16.5%, p< 0.05) and female gender (beta=-7.8 to -9.4%, p< 0.05). By follow-up week 12, predictors of poor PROs included depression, anxiety, fatigue and cirrhosis (p-values< 0.05). In subjects with SVR-12, predictors of residual PRO impairment included anxiety (beta=-5.4 to -7.0%, p< 0.05), depression (beta=-6.8 to -11.3%, p< 0.05), fatigue (beta=-8.0 to -12.4%, p< 0.05) and cirrhosis (beta=-4.4 to -11.8%, p< 0.05).
Conclusions: Fatigue and depression are the main drivers of PRO impairment. During treatment, IFN is another predictor of poor PROs.
