BACKGROUND: Until recently, the approved treatment regimens for patients with hepatitis C virus (HCV) genotypes (GTs) 2 and 3 contain sofosbuvir (SOF) and ribavirin (RBV) for 12 or 24 weeks. The impact of RBV-free pan-genotypic regimen with SOF and velpatasvir (SOF/VEL) on patient-reported outcomes (PROs) of patients with genotype 2 and 3 has not been described. METHODS: PROs data were collected from participants of ASTRAL-2 and ASTRAL-3 studies before, during, and after treatment using 4 PRO instruments (Short Form-36, Chronic Liver Disease Questionnaire-HCV, Functional Assessment of Chronic Illness Therapy-Fatigue, and Work Productivity and Activity Index: Specific Health Problem), and compared between the SOF/VEL and SOF + RBV groups. RESULTS: A total of 818 HCV patients were included: 78% treatment naive, 25% cirrhosis. The rates of nearly all adverse events were lower in the RBV-free SOF/VEL group (all P < .03). The SOF/VEL group also experienced improvement of their PROs by treatment week 4 (+1.8% on average across all PROs), which continued throughout treatment (+4.1%) and post-treatment (+5.5%). In contrast, those in the SOF + RBV group had a modest decline in their PROs starting at treatment week 4 (up to -3.7%), which lasted until the end of treatment (up to -6.4%). In multiple regression analysis, the association of a treatment regimen with end-of-treatment PROs was significant for nearly all PROs; the average beta was +5.0% for the use of SOF/VEL (reference: SOF + RBV). CONCLUSIONS: Patients receiving ribavirin-free SOF/VEL reported significantly better PRO scores during treatment compared with those receiving the RBV-containing regimen. Furthermore, the interferon- and ribavirin-free SOF/VEL regimen resulted in a rapid improvement of PROs in HCV GTs 2 and 3 patients during treatment and after achieving sustained virologic response.
背景:直到最近,丙型肝炎病毒(HCV)基因2型和3型患者的获批治疗方案都包含索磷布韦(SOF)和利巴韦林(RBV),疗程为12周或24周。不含RBV的索磷布韦和维帕他韦泛基因型方案(SOF/VEL)对基因2型和3型患者报告结局(PRO)的影响尚未见报道。 方法:使用4种PRO工具(简明健康状况调查问卷36项简短形式、丙型肝炎慢性肝病问卷、慢性病治疗功能评估-疲劳以及工作效率和活动指数:特定健康问题),在治疗前、治疗期间和治疗后从ASTRAL-2和ASTRAL-3研究的参与者中收集PRO数据,并在SOF/VEL组和SOF + RBV组之间进行比较。 结果:共纳入818例HCV患者:78%为初治患者,25%有肝硬化。不含RBV的SOF/VEL组几乎所有不良事件的发生率均较低(所有P <.03)。SOF/VEL组在治疗第4周时PRO也有改善(所有PRO平均提高1.8%),在整个治疗期间(提高4.1%)和治疗后(提高5.5%)持续改善。相比之下,SOF + RBV组患者的PRO从治疗第4周开始有适度下降(降幅高达3.7%),一直持续到治疗结束(降幅高达6.4%)。在多元回归分析中,治疗方案与治疗结束时的PRO之间的关联对几乎所有PRO均有显著意义;使用SOF/VEL时的平均β值为+5.0%(参考:SOF + RBV)。 结论:与接受含RBV方案的患者相比,接受不含利巴韦林的SOF/VEL治疗的患者在治疗期间报告的PRO评分显著更好。此外,不含干扰素和利巴韦林的SOF/VEL方案在治疗期间以及实现持续病毒学应答后,使HCV基因2型和3型患者的PRO迅速改善。
