Details and patient eligibility

About

Part 1 of the study will assess the effect of 1g, 2g and 5g doses of NWT-03 on systolic and diastolic blood pressure in a cross-over designed study in healthy adults with normal, high normal and mild hypertension. Based on results from this study, one dose will be selected for a placebo controlled parallel study assessing a single dose of NWT-03 on systolic and diastolic blood pressure and endothelial function in a similar population.

Enrollment: 92 patients

Sex: All

Ages: 35 to 75 years old

Volunteers: Accepts Healthy Volunteers
