Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
CTP class B cirrhosis: A single 5 and 10 mg IV bolus injections of Sildenafil. CTP class C cirrhosis: A single 2.5, 5, 8 and 10 mg IV bolus injections of Sildenafil.
iv bolus injection of sildenafil Revatio
Dose escalation will be performed (in different participants). The doses will be as follows: CTP class B cirrhosis: A single 5 and 10 mg IV bolus injections of Sildenafil. CTP class C cirrhosis: A single 2.5, 5, 8 and 10 mg IV bolus injections of Sildenafil.

Primary Outcomes

Number of participants with "suspected adverse reaction" of IV Sildenafil that is both "serious" and "unexpected" as a measure of safety and tolerability.
time frame: The total time to assess the primary outcome measure will be 48 hours after Sildenafil injection (starting from Sildenafil injection time until 48 hours after Sildenafil injection).

Eligibility Criteria

Male or female participants at least 18 years old.

Subjects will be eligible for the study if they meet the following inclusion criteria: 1. Cirrhosis. Diagnosis of cirrhosis will be based on either liver biopsy OR clinical characteristics (e.g. history of ascites or encephalopathy or esophageal varices or gastric varices or splenomegaly or spider angioma or any clinical sign of portal hypertension/cirrhosis), laboratory (e.g. history of thrombocytopenia or history of APRI (Reference: Wai CT, Greenson JK, Fontana RJ, Kalbfleisch JD, Marrero JA, Conjeevaram HS, Lok AS. A simple noninvasive index can predict both significant fibrosis and cirrhosis in patients with chronic hepatitis C. Hepatology 2003;38:518-26) [Aspartate aminotransferase (AST) to platelet ratio index] score consistent with cirrhosis or history of abnormal liver function tests) and abdominal imaging (Magnetic Resonance Imaging or Computed Tomography or ultrasound of the abdomen) data 2. CTP Class B or C cirrhosis 3. Age 18 years or older at the time of enrollment 4. Variceal screening with an upper endoscopy within 1 year before enrollment 5. Renal dysfunction [GFR ≥ 15 and < 60 ml/min/1.73m2 estimated by 6-variable MDRD equation (Reference: Levey AS, Coresh J, Greene T, Stevens LA, Zhang YL, Hendriksen S, Kusek JW, Van Lente F. Using standardized serum creatinine values in the modification of diet in renal disease study equation for estimating glomerular filtration rate. Ann Intern Med 2006;145:247-54)] 6. Hemoglobin level ≥ 8 mg/dl within 4 weeks before enrollment 7. Serum sodium level ≥ 125 mmol/L within 4 weeks before enrollment Subjects will be excluded if they have any of the following: 1.

Treatment with organic nitrates, ritonavir, erythromycin, saquinavir, ketoconazole, itraconazole, cimetidine, bosentan, rifampin, Sildenafil or any other PDE-5 inhibitors, alpha-blockers, and anticoagulants within 7 days before enrollment 4.

Previous reaction to PDE-5 inhibitors including, but not limited to Sildenafil, Vardenafil, Tadalafil, Avanafil (Myocardial infarction, ventricular arrhythmia, sudden cardiac death, cerebrovascular hemorrhage, transient ischemic attack, stroke, transient global amnesia, subarachnoid and intracerebral hemorrhages, seizure, recurrence in seizures, pulmonary hemorrhage, sudden decrease of hearing, loss of hearing, anxiety, prolonged erection, priapism, ocular redness, ocular burning, diplopia, temporary vision loss/decreased vision, ocular swelling, ocular pressure, increased intraocular pressure, retinal problems in the eye, vitreous detachment, vitreous traction, paramacular edema, non-arteritic anterior ischemic optic neuropathy) 6. History of untreated severe left ventricular outflow obstruction (e.g. aortic stenosis, idiopathic hypertrophic subaortic stenosis) 7. History of pulmonary veno-occlusive disease 8. History of unstable angina, myocardial infarctus, life-threatening arrhythmia or stroke within 6 months before enrollment 9. History of retinitis pigmentosa 10.
