NCT ID: NCT02148198

Last Updated: 2014-05-28

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 92 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-05-31

Brief Summary

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.
