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

18. mars 2017 oppdatert av: Geneticure, LLC

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

Detaljert beskrivelse

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.
