The Real-World Safety and Efficacy of Daclatasvir and Asunaprevir for Elderly Patients. Gut Liver 2018; 12:86-93. [PMID: 28798288 PMCID: PMC5753689 DOI: 10.5009/gnl17048] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2017] [Revised: 03/22/2017] [Accepted: 03/22/2017] [Indexed: 01/10/2023] Open
Abstract
Background/Aims Although daclatasvir with asunaprevir was approved in Japan for interferon ineligible or intolerant patients, patients aged ≥75 years were excluded in the phase III trial. The present study aimed to evaluate the safety and efficacy of this therapy for elderly patients aged ≥75 years and to clarify whether an extremely high sustained virological response (SVR) rate can be achieved, even in a real-world setting when patients with resistance-associated substitutions (RASs) to nonstructural protein 5A (NS5A) inhibitors or prior simeprevir failure are excluded. Methods Daclatasvir (60 mg) and asunaprevir (100 mg) were orally administered daily for 24 weeks. Patients without pre-existing NS5A RASs and simeprevir failure were enrolled in this study. Results Overall, 110 patients were treated. The median age was 73 years old. The SVR rates of total patients, those aged ≥75 years, and those aged <75 years were 97% (107/110), 98% (46/47), and 97% (61/63), respectively. The treatment of two patients (2%) was discontinued because of adverse events. Conclusions Daclatasvir with asunaprevir was a safe treatment, even in patients aged ≥75 years. When patients without pre-existing NS5A RASs and prior simeprevir failure were selected, an extremely high SVR rate could be achieved irrespective of age.

Simeprevir-Based Triple Therapy with Reduced Doses of Pegylated Interferon α-2a Plus Ribavirin for Interferon Ineligible Patients with Genotype 1b Hepatitis C Virus. Gut Liver 2018; 11:551-558. [PMID: 28506030 PMCID: PMC5491091 DOI: 10.5009/gnl16525] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2016] [Revised: 12/10/2016] [Accepted: 12/23/2016] [Indexed: 12/28/2022] Open
Abstract
Background/Aims The present study aimed to evaluate the safety and efficacy of simeprevir-based triple therapy with reduced doses of pegylated interferon (PEG-IFN) and ribavirin for interferon (IFN) ineligible patients, such as elderly and/or cirrhotic patients, and to elucidate the factors contributing to a sustained virologic response (SVR). Methods One hundred IFN ineligible patients infected with genotype 1b hepatitis C virus (HCV) were treated. Simeprevir (100 mg) was given orally together with reduced doses of PEG-IFN-α 2a (90 μg), and ribavirin (200 mg less than the recommended dose). Results The patients’ median age was 70 years, and 70 patients were cirrhotic. Three patients (3%) discontinued treatment due to adverse events. The SVR rate was 64%. Factors that significantly contributed to the SVR included the γ-glutamyl transferase and α-fetoprotein levels, interleukin-28B (IL28B) polymorphism status, and the level and reduction of HCV RNA at weeks 2 and 4. The multivariate analysis showed that the IL28B polymorphism status was the only independent factor that predicted the SVR, with a positive predictive value of 77%. Conclusions Simeprevir-based triple therapy with reduced doses of PEG-IFN and ribavirin was safe and effective for IFN ineligible patients infected with genotype 1b HCV. IL28B polymorphism status was a useful predictor of the SVR.

Low-Dose Pegylated Interferon α-2b Plus Ribavirin for Elderly and/or Cirrhotic Patients with Genotype 2 Hepatitis C Virus. Gut Liver 2017; 10:617-23.

Abstract
Background/Aims This study aimed to predict sustained viral response (SVR) to low-dose pegylated interferon (PEG-IFN) plus ribavirin of elderly and/or cirrhotic patients with genotype 2 hepatitis C virus (HCV) using viral response within 2 weeks. Methods Low-dose PEG-IFN-α-2b plus ribavirin was administered to 50 elderly and/or cirrhotic patients with genotype 2 HCV for 24 weeks. The dynamics of HCV RNA and HCV core antigen levels within 2 weeks were measured. Results The patients’ median age was 66 years. There were 21 male and 29 female patients. The median baseline HCV RNA level was 5.7 log IU/mL. Rapid viral response was achieved in 17 patients (34%), SVR in 28 (56%), and two (4%) discontinued treatment. Univariate analysis of factors contributing to SVR showed significant differences for sex, baseline virus level, and response within 4 weeks. When 40 fmol/L was set as the cutoff value for the core antigen level at 1 week, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for predicting SVR were 93%, 75%, 84%, 88%, and 85%, respectively. Conclusions Low-dose PEG-IFN plus ribavirin was a safe and cost-effective treatment for elderly and/or cirrhotic patients with genotype 2 HCV, and the viral response within 2 weeks was a useful predictor of SVR.

Prediction of Sustained Virological Response to Telaprevir-Based Triple Therapy Using Viral Response within 2 Weeks. HEPATITIS RESEARCH AND TREATMENT 2014; 2014:748935. [PMID: 25328696 PMCID: PMC4195394 DOI: 10.1155/2014/748935] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/13/2014] [Revised: 09/21/2014] [Accepted: 09/22/2014] [Indexed: 01/04/2023]
Abstract
The aim of the present study was to predict sustained virological response (SVR) to telaprevir with pegylated interferon (PEG-IFN) and ribavirin using viral response within 2 weeks after therapy initiation. Thirty-six patients with genotype 1 hepatitis C virus (HCV) and high viral load were treated by telaprevir-based triple therapy. SVR was achieved in 72% (26/36) of patients. Significant differences between the SVR group and non-SVR group were noted regarding response to prior PEG-IFN plus ribavirin, interleukin (IL)28B polymorphism, amino acid substitution at core 70, cirrhosis, hyaluronic acid level, and HCV-RNA reduction within 2 weeks. Setting 4.56 logIU/mL as the cut-off value for HCV-RNA reduction at 2 weeks, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for predicting SVR were 77%, 86%, 95%, 50%, and 79%, respectively, and for neither the IL28B minor allele nor core 70 mutant were 80%, 71%, 91%, 50%, and 78%, respectively. In conclusion, evaluation of viral reduction at 2 weeks or the combination of IL28B polymorphism and amino acid substitution at core 70 are useful for predicting SVR to telaprevir with PEG-IFN and ribavirin therapy.
