Clinical Research

Clinical Trials

Offering pulmonary vascular disease patients the latest in diagnostics, prevention, and treatment is at the forefront of the Vera Moulton Wall Center's mission. In addition to access to the latest large scale pharmaceutical trials, the Center is also conducting a number of smaller Stanford initiated trials. These trials, which are only available at Stanford, have been developed by Stanford researchers and are bringing the latest discoveries out of the laboratory and to the bedside.

The Center has anywhere from 5-10 studies actively recruiting patients most of the time. Studies range from investigating the safety and efficacy of new medications and evaluating combination therapies of FDA approved therapies to participating in database and biobanking projects.

PH Patient Database Project

The Vera Moulton Wall Center has one of the largest academic pulmonary hypertension databases in the world.  Developed almost 20 years ago it has served as the model for other large scale PH databases.  In addition to standard demographic data, the database tracks patient visits, admissions, and more than 200 other data points from various tests and lab studies.  Stanford PH patients simply need to sign an informed consent and agree to participate, no other visits or tests are needed beyond routine patient care. 

This aggregate data allows researchers to look at the 'bigger picture' and look for trends and patterns among larger PH populations and also much smaller, very specific groups to better understand patterns and trends across groups of PH patients.
