Safety and Efficacy of Simeprevir/Sofosbuvir in Hepatitis C-Infected Patients With Compensated and Decompensated Cirrhosis.

ABSTRACT:

Unlabelled

Risks and benefits of simeprevir plus sofosbuvir (SIM+SOF) in patients with advanced cirrhosis are unknown. We assessed the safety and sustained virological responses (SVR) of SIM+SOF with and without ribavirin (RBV) in patients with Child-Pugh (CP)-B/C versus CP-A cirrhosis and compared to matched untreated controls. This study was of a multicenter cohort of adults with hepatitis C virus genotype 1 and cirrhosis treated with SIM+SOF with/without RBV for 12 weeks. Controls were matched on treatment center, age, CP class, and Model for End-Stage Liver Disease (MELD) score. Of 160 patients treated with SIM+SOF with/without RBV, 35% had CP-B/C and 64% had CP-A, with median baseline MELD 9 (interquartile range, 8-11). Sustained virological response at week 12 (SVR12) was achieved by 73% of CP-B/C versus 91% of CP-A (P < 0.01). CP-B/C versus CP-A had more early treatment discontinuations (11% vs. 1%), adverse events (AEs) requiring hospitalization (22% vs. 2%), infections requiring antibiotics (20% vs. 1%), and hepatic decompensating events (20% vs. 3%; all P < 0.01). There were 2 deaths: 1 CP-B/C (liver related) and 1 CP-A (not liver related). In multivariate analysis, CP-B/C independently predicted lack of SVR12 (odds ratio, 0.27; 95% confidence interval: 0.08-0.92). In comparing SIM+SOF-treated patients versus matched untreated controls, AEs requiring hospitalization (9% vs. 13%; P = 0.55), infections (8% vs. 6%; P = 0.47), and events of decompensation (9% vs. 10%; P = 0.78) occurred at similar frequency.

Conclusions

SIM+SOF with/without RBV has lower efficacy and higher rates of AEs in patients with CP-B/C cirrhosis, compared to CP-A. Frequency of adverse safety outcomes were similar to matched untreated controls, suggesting that safety events reflect the natural history of cirrhosis and are not related to treatment.

Project description:UnlabelledEffective antiviral therapy is essential for achieving sustained virological response (SVR) in hepatitis C virus (HCV)-infected patients. The phase 2 COSMOS study reported high SVR rates in treatment-naive and prior null-responder HCV genotype (GT) 1-infected patients receiving simeprevir+sofosbuvir±ribavirin for 12 or 24 weeks. OPTIMIST-1 (NCT02114177) was a multicenter, randomized, open-label study assessing the efficacy and safety of 12 and 8 weeks of simeprevir+sofosbuvir in HCV GT1-infected treatment-naive and treatment-experienced patients without cirrhosis. Patients were randomly assigned (1:1; stratified by HCV GT/subtype and presence or absence of NS3 Q80K polymorphism [GT1b, GT1a with Q80K, GT1a without Q80K]), prior HCV treatment history, and IL28B GT [CC, non-CC]) to simeprevir 150 mg once daily+sofosbuvir 400 mg once daily for 12 or 8 weeks. The primary efficacy endpoint was SVR rate 12 weeks after end of treatment (SVR12). Superiority in SVR12 was assessed for simeprevir+sofosbuvir at 12 and 8 weeks versus a composite historical control SVR rate. Enrolled were 310 patients, who were randomized and received treatment (n = 155 in each arm). SVR12 with simeprevir+sofosbuvir for 12 weeks (97% [150/155; 95% confidence interval 94%-100%]) was superior to the historical control (87%). SVR12 with simeprevir+sofosbuvir for 8 weeks (83% [128/155; 95% confidence interval 76-89%]) was not superior to the historical control (83%). The most frequent adverse events were nausea, headache, and fatigue (12-week arm: 15% [23/155], 14% [22/155], and 12% [19/155]; 8-week arm: 9% [14/155], 17% [26/155], and 15% [23/155], respectively). No patients discontinued treatment due to an adverse event. One (1%, 12-week arm) and three (2%, 8-week arm) patients experienced a serious adverse event (all unrelated to study treatment).ConclusionSimeprevir+sofosbuvir for 12 weeks is highly effective in the treatment of HCV GT1-infected patients without cirrhosis, including those with Q80K.

Project description:BackgroundWith the appearance of oral direct-acting antivirals (DAAs), the field of hepatitis C virus (HCV) treatment has been dramatically changed. This evolution makes possible for all oral treatments to be available for the treatment of HCV-infected patients. The aims of this review were to report the efficacy and safety of sofosbuvir (SOF)-based regimens for the treatment of patients with chronic HCV infection and to provide our clinical perspectives on these regimens.MethodsA literature search of clinical studies published in PubMed and posted on ClinicalTrials.gov website was performed to identify studies evaluating the efficacy or safety of SOF-containing treatment regimens.ResultsA total of 23 clinical trials were examined in the review. The evaluated SOF-based regimens are as follows: SOF/daclatasvir (DCV) ± ribavirin (RBV), SOF/ledipasvir (LDV) ± RBV, SOF/simeprevir (SMV), SOF/velpatasvir (VEL) ± RBV, and SOF/RBV ± peginterferon (peg-IFN). These SOF-based regimens were at least effective and safe for HCV-infected patients with or without cirrhosis. The SOF/VEL ± RBV regimen, a pan-genotypic DAA regimen, was effective for the treatment of patients with HCV genotype 1, 2, 3, 4, 5, or 6 infection. The 24-week SOF/RBV regimen was as effective as the 12-week SOF/RBV/peg-IFN regimen. Patients with HCV genotype 3 infection could have benefits from the use of the 24-week SOF/RBV regimen. For cirrhotic patients with HCV genotype 3 infection, the 12-week SOF/RBV/peg-IFN regimen could be considered as an alternative treatment option when access to SOF-based regimens with other DAAs is limited. In the included studies, significant adverse events due to SOF-based regimens were not reported.ConclusionThe clinical trials suggest that SOF-based treatment regimens for HCV-infected patients with or without cirrhosis can be at least effective and safe patient-convenient medications. However, it is necessary to monitor HCV-infected patients, since rare adverse events, drug-drug interactions, and drug-disease interactions can occur in real clinical settings.

Project description:UnlabelledHepatitis C virus (HCV)-infected patients with cirrhosis are historically a difficult-to-treat population and are at risk of hepatic decompensation. In the phase 2 COSMOS study that evaluated simeprevir (HCV NS3/4A protease inhibitor) + sofosbuvir (HCV nucleotide analogue NS5B polymerase inhibitor) ± ribavirin for 12 or 24 weeks in HCV genotype (GT)1-infected patients, high rates of sustained virologic response 12 weeks after planned end of treatment (SVR12) were achieved, including in patients with cirrhosis (METAVIR score F4). This phase 3, open-label, single-arm study (OPTIMIST-2 [NCT02114151]) evaluated the efficacy and safety of 12 weeks of simeprevir + sofosbuvir in HCV GT1-infected treatment-naive or treatment-experienced patients with cirrhosis. Patients (aged 18-70 years) with chronic HCV GT1 infection and documented presence of cirrhosis received oral simeprevir 150 mg once daily + sofosbuvir 400 mg once daily for 12 weeks. The primary efficacy endpoint of the study was the proportion of patients achieving SVR12 versus a composite historical control (SVR12 rate of 70%). Safety and patient-reported outcomes were assessed. Overall, 103 patients received treatment. SVR12 with simeprevir + sofosbuvir (83%, 95% confidence interval 76%-91%) met the primary objective of superiority versus the historical control (70%). SVR12 rates for treatment-naive and treatment-experienced patients were 88% (44/50) and 79% (42/53), respectively. Adverse events occurred in 72 (70%) patients, with most (64%) being grade 1 or 2. Serious adverse events (none considered related to study treatment) occurred in five (5%) patients, and three (3%) patients discontinued all study treatment due to adverse events. Patient-reported outcomes improved from baseline to follow-up week 12.ConclusionSimeprevir + sofosbuvir for 12 weeks achieved superiority in SVR12 rates versus the historical control in treatment-naive and treatment-experienced HCV GT1-infected patients with cirrhosis and was generally safe and well tolerated.
