Clinical Trial Summary

The purpose of this study is to evaluate and compare the efficacy of B244 in treating patients with hypertension.

Description:

This is a Prospective, Vehicle Controlled, Double Blinded, Multicenter, Randomized Phase II trial, comparing the effect of twice daily B244 application for 4 weeks vs vehicle application on BP and inflammatory biomarkers.

Eligibility

Inclusion Criteria:

• Willing to refrain from using any antihypertensive treatments, other than the investigational product, including herbal supplements, systemic use of steroids, chronic use of NSAIDS, any antihypertensive agents, such as beta-blockers, diuretics, ACE inhibitors, CA channel blockers, Alpha blockers, Central Acting agents and vasodilators.
• Ability to comprehend and comply with procedures
• Agree to commit to participate in the current protocol
• Provide written informed consent prior to any study procedure being performed (all subjects should be able to understand the informed consent form and any other documents that subjects are required to read)

Exclusion Criteria:

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Difference in Inflammatory Biomarkers Between Active and Vehicle Groups	To evaluate if B244 administration on the skin twice daily will affect the levels of immune biomarkers.	Baseline-Week 4
Other	Microbial Content	Evaluate if B244 administration on skin twice daily will affect the microbial content on collected skin swab samples.	Baseline, Day 28, Day 42
Other	Microbial Composition	Evaluate if B244 administration on skin twice daily will affect the microbial composition on collected skin samples.	Baseline, Day 28, Day 42
Primary	Number of Participants With Treatment-related Adverse Events as Assessed by CTCAE v4.0	Safety and tolerability endpoints will consist of all treatment related adverse events reporting during the study duration.	Baseline-6 weeks
Primary	Difference in Mean in Clinic Systolic BP Between the Active and Vehicle Groups	Clinical systolic blood pressure (BP) readings were obtained at every visit using a calibrated electronic sphygmomanometer. Three measurements were taken at each visit. The average of the second and third readings was documented. Data was analyzed using mixed-effects model repeated measures (MMRM). Difference was calculated as the change from Baseline to Day 28.	Baseline-Week 4
Secondary	Difference in Mean in Clinic Diastolic BP Between the Active and Vehicle Group	Clinical diastolic blood pressure (BP) readings were obtained at every visit using a calibrated electronic sphygmomanometer. Three measurements were taken at each visit. The average of the second and third readings was documented. Data was analyzed using mixed-effects model repeated measures (MMRM). Difference was calculated as the change from Baseline to Day 28.	Baseline-Week 4
Secondary	Difference in Mean Ambulatory Systolic and Diastolic Daytime Blood Pressure	An ambulatory blood pressure measurement (ABPM) device was placed on a subject's arm during the clinic visit to record 24-hour blood pressure and heart rate measurements.	Baseline-Week 4
