  Purpose

This is a multi-center, randomized, placebo-controlled, time-lagged, parallel-group study in healthy and hypertensive subjects to evaluate safety and tolerability of the vaccine CYT006-AngQb. The trial is double-blind for active vs. placebo within each treatment arm, but open with respect to AngQb dose escalation.

In the first arm, 16 healthy normotensive volunteers are treated with a one dose regimen consisting of a single s.c. injection of 100µg of AngQb or placebo. Upon satisfying safety and tolerability profile, as judged by the independent safety monitoring board, arm two is enrolled.

In arm two 36 patients with mild to moderate hypertension receive three s.c. injections of 100µg CYT006-AngQb (24 patients) or placebo (12 patients). The second and third injections are given 4 and 12 weeks after the first injection, respectively. Upon satisfying safety and tolerability profile, as judged by the independent safety monitoring board, arm three is enrolled.

In arm three 36 patients with mild to moderate hypertension receive three s.c. injections of 300µg CYT006-AngQb (24 patients) or placebo (12 patients). The second and third injections are given 4 and 12 weeks after the first injection, respectively.

The primary objective of the trial is to evaluate safety / tolerability of 3 dose regimens of CYT006-AngQb in healthy volunteers and patients with mild to moderate essential hypertension. Secondary objectives include the assessment of pharmacodynamic effects and their dose-response (immunogenicity and biomarkers of the renin-angiotensin system), and the exploration of clinical efficacy (effects on systolic and diastolic blood pressure)
