简要总结
- Achieve sustained virologic response (SVR) in patients infected with HCV genotype 1, cirrhosis, and early clinical decompensation using 12 weeks of Olysio/Sovaldi/Ribavirin (or known as: Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin (RBV).
- Hepatic improvement during and after Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin(RBV) treatment using a new test of liver function, HepQuant-SHUNT.
详细描述
The proposed study will quantify hepatic improvement and antiviral efficacy of the open-label interferon-free combination of 12 weeks of simeprevir (SMV, Simeprevir), sofosbuvir (SOF, Sofosbuvir), and ribavirin (RBV) in patients with HCV genotype 1 infection and early decompensation of cirrhosis. Early decompensation is defined by clinical complications or laboratory deterioration but with a model for end-stage liver disease (MELD) score of 10 or less.
The primary objective of this trial is determination of hepatic functional improvement as measured by the HepQuant (HQ) test during and after Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin(RBV). Standard laboratory tests, clinical models (MELD, CTP), liver biopsy, hepatic venous pressure gradient (HVPG), and other imaging tests are insensitive, invasive, or nonspecific.
They may not adequately assess the liver's improvement after viral eradication. In contrast, HepQuant (HQ) tests (Systemic Hepatic Filtration Rate (HFR), Portal HFR, SHUNT,single point cholate concentration (STAT), and DSI) are noninvasive, sensitive, specific, and target an endogenous function, the hepatic uptake of cholate. HQ tests uses serum sampling over a time period of up to 90 minutes to quantify the systemic circulation, portal circulation, and portal-systemic shunt and to derive a disease severity index (DSI) in intact human subjects. The primary endpoint in this treatment trial will be improvement in hepatic function measured by HepQuant (HQ) tests that occurs during and after successful Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin(RBV).

入选标准
- •HCV genotype 1 infection (all subtypes and Q80K a type of mutation are allowed), and have been approved by a third party payer for the FDA-approved combination of sofosbuvir (SOF) plus ribavirin. The study drug, simeprevir (SMV)
- •Biopsy proven cirrhosis, or clinical cirrhosis with APRI (AST to Platelet Ratio Index to determine clinical cirrhosis)> 2, Fibrotest > 0.75, or Fibroscan > 12.5 Results Stiffness (kPa).
- •MELD 10 or less
- •Expected survival without liver transplantation of >1 year
- •Patients with Hepatocellular carcinoma (HCC) are included as long as disease MELD is 10 or less, and anticipated time to transplant is >1 year. An example, might be a patient with a subcentimeter HCC who is undergoing serial imaging to document tumor growth to tumor diameter >2 cm prior to listing for transplantation (in order to secure MELD exception). In this case, there could be a time lapse of 3 months or more while monitoring tumor growth, and a further time lapse of 9 months or more until the time of transplantation.
- •Patients with TIPS or Portal Vein Thrombosis may be included. -
排除标准
- •Inability to provide informed consent
- •Known hypersensitivity or serious adverse reaction to any of the study drugs
- •Age <18 or >80 years
- •Pregnancy as determined by subject reporting and urine dipstick testing at screening.
- •Other underlying chronic liver disease - examples that would exclude a patient from participating include but are not limited to nonalcoholic liver disease, alcoholic liver disease, hepatitis B, hemochromatosis, and autoimmune liver disease.
- •Serious other underlying medical condition - examples include but are not limited to unstable cardiovascular, coronary, or pulmonary disease including right and left sided heart failure, active malignancy other than HCC, or serious infection.
- •Estimated creatinine clearance < 30 mL min-1 1.73 m2 surface area (BSA)
- •Hemoglobin <10 g/dL
- •Neutrophils <500 /μL
- •Platelets <50,000 /μL
- •Bilirubin >4 mg/dL
- •Albumin < 2.8 g/dL
- •Blood Clotting: International Normalised Ratio (INR) > 2
- •Child-Turcotte-Pugh class B or C; or, CTP score >7
- •Conditions that would affect the absorption of orally administered cholate used in the HepQuant® test - such as, extensive intestinal resection, diabetic gastroparesis, and ileal disease or resection.
- •Concomitant use of both beta-blocker and ACE inhibitor
- •Subjects taking any other medications with significant drug drug interactions related to the study medications (sofosbuvir, simeprevir, or ribavirin) who cannot discontinue or substitute that medication, will be excluded.

时间窗: 12 weeks
Number of participants who cleared Hepatitis C (HCV) after 12 weeks was collected (HCV RNA level was "Not Detected".
Hepatic Improvement During and After Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin(RBV) Treatment Using a New Test of Liver Function, HepQuant-SHUNT: 12 Weeks
时间窗: 12 Weeks
Liver function as assessed via MELD score. The Model For End-Stage Liver Disease (MELD) score assesses the severity of patient liver disease. Possible scores range from 6 to 40, with higher scores indicating more severe liver disease and a worse outcome.
