sorafenib for hepatopulmonary syndrome

Conditions: Hepatopulmonary Syndrome

Summary: the main purpose of this clinical trial is to determine the safety and effects of the study drug, sorafenib, in adults diagnosed with hepatopulmonary syndrome (hps). the study will evaluate how well the drug is tolerated and its effect on the level of oxygen in the blood and the function of the lung vessels.
