Medication Treatment Study for snOH in Subjects with Primary Autonomic Failure

The SEQUOIA Study is a research study looking at a study drug for people with conditions such as Parkinson’s disease (PD) or multiple system atrophy (MSA) who have a drop in blood pressure upon standing. We want to learn how safe the study drug is and whether it can reduce these symptoms. Participation will last about 9 weeks, with 7 study visits.

In order to participate you must meet the following criteria:

• Have been diagnosed with Parkinson’s disease (PD) or multiple system atrophy (MSA),
• Have symptoms such as dizziness, light-headedness, feeling faint, or feeling like you might black out upon standing.
• Are 30 years of age or older.
• Meet additional eligibility criteria.

This is a partial list of inclusion and exclusion criteria.
