Clinical Trial 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.

• Subjects may not be receiving treatment involving experimental drugs,

• If the subject has been in a recent experimental trial, these must have been completed not less than 60 days prior to this study. An exception will be made where subjects have participated in part 1 of the study,

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in average daytime systolic blood pressure at 5 days	Blood pressure will be measured two times for 48h during each intervention period; 48h before the baseline measurement and 5 days after baseline measurement.	For both intervention periods: 48h ABPM before baseline visit and 5 days after baseline visit	No
Secondary	Change from baseline in average daytime diastolic blood pressure at 5 days	Blood pressure will be measured two times for 48h during each intervention period; 48h before the baseline measurement and 5 days after baseline measurement.	48h ABPM before baseline visit and 5 days after baseline visit	No
Secondary	Change from baseline in 48h systolic blood pressure at 5 days	Blood pressure will be measured two times for 48h during each intervention period; 48h before the baseline measurement and 5 days after baseline measurement.	48h ABPM before baseline visit and 5 days after baseline visit	No
Secondary	Change from baseline in 48h diastolic blood pressure at 5 days	Blood pressure will be measured two times for 48h during each intervention period; 48h before the baseline measurement and 5 days after baseline measurement.	48h ABPM before baseline visit and 5 days after baseline visit	No
