Patient-reported outcomes assessment in chronic hepatitis C treated with sofosbuvir and ribavirin: The VALENCE study

Published:April 07, 2014DOI:https://doi.org/10.1016/j.jhep.2014.04.003

      Background & Aim

      Interferon (IFN) negatively impacts patients’ well-being and patient-reported outcomes (PROs). Our aim was to assess PROs during treatment with an IFN-free regimen [sofosbuvir (SOF) + ribavirin (RBV)].

      Methods

      Four PRO questionnaires [Short Form-36 (SF-36), Chronic Liver Disease Questionnaire-HCV (CLDQ-HCV), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Work Productivity and Activity Index: Specific Health Problem (WPAI:SHP)] were administered at baseline, end-of-treatment and post-treatment to 334 HCV genotype 2 and 3 patients (naïve or treatment-experienced) enrolled in the VALENCE study. Of these, 250 genotype 3 patients were treated for 24 weeks while 73 genotype 2 and 11 genotype 3 patients received 12 weeks of treatment.

      Results

      Baseline PRO scores were similar between the two arms of the study. Throughout and after treatment, patients receiving 12 or 24 weeks had similar FACIT-F, CLDQ-HCV, SF-36 and WPAI:SHP scores (all p >0.05). Compared to their own baseline scores, patients receiving SOF + RBV experienced modest declines in some aspects of SF-36, CLDQ-HCV, fatigue and WPAI:SHP scores (p = 0.04 to <0.0001). By follow-up week 12, all PRO scores returned to the pre-treatment levels (p >0.05). In patients achieving SVR-12 (regardless of the regimen), significant improvements were noted in general health (p = 0.0004), CLDQ-HCV (p <0.0001), fatigue (p = 0.005), emotional well-being (p <0.0001) and physical component summary score of SF-36 (p = 0.0022). In multivariate analysis, baseline depression, fatigue, insomnia, cirrhosis, and treatment-related adverse events were the most consistent predictors of PRO impairment (all p <0.05).

      Conclusions

      PROs are minimally impacted by SOF + RBV regimens. An additional 12 weeks of treatment does not substantially add to the PRO burden.
