Relationship Between Genes Important in Blood Pressure Regulation and Blood Pressure Therapy in Hypertension

Assessment of the Relationship Between Genes That Encode Proteins Important in Blood Pressure Regulation and Blood Pressure Therapy in Patients With Hypertension

Whether patients with a functional genotype of a protein important in blood pressure regulation respond better to a drug therapy class/combination of therapy classes that target that specific pathway using the Geneticure panel for high blood pressure

2.1 Study Design and Protocol Overview This is a post-hoc association study of patients who have been diagnosed with high blood pressure and have been stable on medication treatment for at least 6 months. The purpose of this study is to evaluate the relationship between optimal medication therapy (or the therapy that has resulted in the most stable blood pressure for that particular patient) and the predicted optimal medication therapy based on a patient's genetic profile.

Chart reviews for the patient's history of antihypertensive therapy will be coupled with buccal swabs and blood pressure readings collected from eligible patients who have provided informed consent. The swab will be analyzed for fourteen genetic variants that are associated with antihypertensive therapy response (efficacy, side-effects).

2.2 Study Objective To assess the relationship between the drug therapy class/combination of therapy classes that resulted in the best blood pressure control for a patient vs. what the Geneticure high blood pressure panel would have predicted.

2.3 Secondary Objectives

• To assess the clinical time to achieve optimal blood pressure treatment.
• To assess the number of office visits required to achieve optimal blood pressure treatment.

Inclusion Criteria:

   • Angiotensin Receptor Blocker (ARB)
   • Beta-blockers

Exclusion Criteria:

1. Subject has clinically significant kidney disease as determined by the investigator.
2. Subject has clinically significant cardiac disease as determined by the investigator.
3. Subject has clinically significant vascular disease as determined by the investigator.
4. Subject has a diagnosis of secondary hypertension or is experiencing a complication of pregnancy.
5. Subject is currently prescribed and taking any additional class of medication(s) for high blood pressure not included in the list above, with the exception of a Ca+ channel blocker.
6. Subject has Systolic BP > 190 or Diastolic BP > 120 documented within the six months prior to visit.
7. Subject has a regular alcohol intake of greater than 21 units per week in the past 6 months
8. Subject has smoked greater than two packs of cigarettes (total) or equivalent nicotine intake in the past 6 months.
9. Subject has an anticipated survival less than 12 months.
