Patients with chronic hepatitis C virus (HCV) and cirrhosis are in critical need of treatment that is both effective and tolerable. The combination of simeprevir (SMV), a protease inhibitor, and sofosbuvir (SOF), a polymerase inhibitor, without peginterferon and/or ribavirin (PEGINF/RBV) has been shown to achieve sustained virologic response (SVR) exceeding 90% in patients with HCV genotype 1 with prior nonresponse and/or cirrhosis. The present report describes the efficacy of SMV and SOF in patients with cirrhosis, prior or current hepatic decompensation, and other contraindications to PEGINF/RBV.
A total of 120 consecutive patients with cirrhosis and contraindications to PEGINF/RBV were treated with SMV and SOF for 12 weeks. The primary end point was SVR at 12 weeks after the completion of treatment.
The mean age of the cohort was 60 years; 63% were male, 48% were Caucasian, 44% were African American, 69% were of genotype 1A, 49% were treatment naïve, 96% were interleukin-28B non-CC, 33% were of Child class B or C, and 25% had prior hepatic decompensation. The SVR by intention-to-treat was 81% with a relapse rate of 14%. The SVR by per-protocol analysis was 87% with a relapse rate of 13%. The only baseline factor associated with SVR by multifactor analysis was Child class. SVR in patients with Child class A, B, and C was 87, 77, and 67%, respectively. Eleven percent of the patients developed severe adverse events, which included sepsis (two), variceal bleeding (two), hepatocellular carcinoma (two), and hyperbilirubinemia (eight). One of the patients with sepsis died. Two patients developed relapse more than 12 weeks after stopping SMV and SOF.
The combination of SMV and SOF achieves high rates of SVR in patients with advanced cirrhosis but is lower with worsening Child class.
慢性丙型肝炎病毒(HCV)和肝硬化患者迫切需要有效且耐受性良好的治疗方法。蛋白酶抑制剂西米普明(SMV)和聚合酶抑制剂索非布韦(SOF)联合使用,不使用聚乙二醇干扰素和/或利巴韦林(PEGINF/RBV),已被证明在既往无应答和/或肝硬化的HCV 1型患者中实现持续病毒学应答(SVR)的比例超过90%。本报告描述了SMV和SOF在肝硬化、既往或当前肝失代偿以及其他PEGINF/RBV禁忌证患者中的疗效。
总共120例连续的肝硬化且有PEGINF/RBV禁忌证的患者接受了SMV和SOF治疗12周。主要终点是治疗完成后12周时的SVR。
该队列的平均年龄为60岁;63%为男性,48%为白种人,44%为非裔美国人,69%为1A基因型,49%为初治患者,96%为白细胞介素-28B非CC型,33%为Child B或C级,25%有既往肝失代偿。意向性治疗的SVR为81%,复发率为14%。符合方案分析的SVR为87%,复发率为13%。多因素分析中与SVR相关的唯一基线因素是Child分级。Child A、B和C级患者的SVR分别为87%、77%和67%。11%的患者发生了严重不良事件,包括败血症(2例)、静脉曲张出血(2例)、肝细胞癌(2例)和高胆红素血症(8例)。其中1例败血症患者死亡。2例患者在停用SMV和SOF后12周以上出现复发。
SMV和SOF联合使用在晚期肝硬化患者中实现SVR的比例较高,但随着Child分级恶化而降低。
