The Pfizer New Haven Clinical Research Unit is conducting a study of a new investigational drug being studied to treat people with pulmonary (lung) arterial hypertension (PAH). An “investigational drug” is a drug that has not been approved to treat disease. PAH is a disease that affects the arteries of the lungs, making them smaller and less able to carry blood. This causes the heart to work harder to pump blood through the lungs which causes high blood pressure (hypertension) on the right side of the heart. This is different from “typical” high blood pressure (as measured, for example, in your arm) which comes from increased pressures in the left side of the heart. This research study will be the first time the study drug will be given to people. Study drug and placebo will be given as a suspension (liquid), which you will drink or as 1 or more tablets that you will swallow, depending on which part of the study you are accepted into.
