The Lancet：高血压疫苗有望五年内上市
ambulatory blood pressure was measured before treatment and at week 14. The primary outcomes were safety and tolerability. Analyses were done by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00500786.
Findings
Two patients in the 100 μg group, three in the 300 μg group, and none in the placebo group discontinued study treatment. All patients were included in safety analyses; efficacy analyses did not include the five dropouts, for whom no data were available at week 14. Five serious adverse events were reported (two in the 100 μg group, two in the 300 μg group, and one in the placebo group); none were deemed to be treatment related. Most side-effects were mild, transient reactions at the injection site. Mild, transient influenza-like symptoms were seen in three patients in the 100 μg group, seven in the 300 μg group, and none in the placebo group. In the 300 μg group, there was a reduction from baseline in mean ambulatory daytime blood pressure at week 14 by −9·0/−4·0 mm Hg compared with placebo (p=0·015 for systolic and 0·064 for diastolic). The 300 μg dose reduced the early morning blood-pressure surge compared with placebo (change at 0800 h −25/−13 mm Hg; p<0·0001 for systolic, p=0·0035 for diastolic).
Interpretation
Immunisation with CYT006-AngQb was associated with no serious adverse events; most observed adverse events were consistent with local or systemic responses similar to those seen with other vaccines. The 300 μg dose reduced blood pressure in patients with mild-to-moderate hypertension during the daytime, especially in the early morning.
