Proof of Concept Study To Evaluate the Efficacy and Justification Of OBV/PTV/r and DSV In Adults With Chronic Hepatitis C Virus Genotype 2K/1B
An Open-Label, Proof of Concept Study To Evaluate the Efficacy and Justification Of OBV/PTV/r and DSV In Adults With Chronic Hepatitis C Virus (HCV) Infection Genotype 2K/1B- NINJA Study
HCV infection is one of the most prevalent etiologies for liver cirrhosis and hepatocellular carcinoma. HCV is highly heterogeneous, with seven confirmed major genotypes. Each genotype displays a different geographic distribution.
Since different HCV genotypes react differently on available antiviral therapies, the correct identification of HCV genotype serves as a marker of responsiveness and an indicator for duration of treatment.
The recombinant HCV genotype 2k/1b was first described in Saint Petersburg in 2002.
A sequencing strategy led to the detection of HCV genotype 2k/1b. However, clinical laboratories often use the VERSANT HCV Genotype 2.0 Assay for routine HCV genotyping. This assay may potentially misclassify these HCV strains as genotype 2a/2c. Based on these findings, the number of patients with 2k/1b may be underestimated.
AbbVie's IFN-free regimen for the treatment of chronic HCV genotype 1b infection includes 3 DAAs with distinct mechanisms of action and non-overlapping resistance pattern to target HCV proteins essential for viral replication. The high efficacy of the 3D regimen was proven in registration clinical trials and RW for 1b population.
3D regimen has not been evaluated for patients with HCV genotype 2K/1B. Primary Objective
• Evaluate the efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir (3D) in an interferon-free treatment regimen as assessed by SVR in adult patients with HCV 2k/1b.
Study Design:
.The study will include 1 group. Patients with HCV GT 2k1b will be treated according to label recommendation as for GT1b (with and without cirrhosis) for 12 weeks. All subjects will receive Ombitasvir/Paritaprevir/Ritonavir and Dasabuvir. Subjects will be assessed for antiviral response, clinical outcomes, patient reported adverse events and presence and emergence of resistance associated variants. Subjects will be followed for up to 12 weeks of treatment and extra 24 weeks of follow up. Scheduled visits will include: physician assessment and blood tests including HCV resistance mutations.
調査の概要
詳細な説明
Study Procedures:
Initial screening period:
HCV GT2K/1B -infected subjects who will be meeting eligibility criteria, will provide written informed consent, perform baseline RAS testing and will be enrolled to the study.
Baseline period:
On day 0, all patients will be assessed by a general physical examination, blood and urine tests including HCV resistance mutations (elaborated in the budget file), Fibroscan or SHEAR WAVE Elastography and abdominal ultrasound. After the initial assessment all included will be allocated for treatment.
Study configuration:
The study will include 1 group of patients infected GT 2k1b. Patients will be treated according to label recommendation for GT1b (with and without cirrhosis) for 12 weeks. All subjects will receive Ombitasvir/Paritaprevir/Ritonavir and Dasabuvir. Scheduled visits will take place in 0, 4, 12 and 24 weeks for all patients.
All visits will include: physician assessment and blood tests as elaborated in the Study Flowchart. Subjects will be assessed for antiviral response, clinical outcomes, patient reported adverse events and presence and emergence of resistance associated variants.
