ADASUVE 2-dose Thorough QT/QTc Study

Thorough QT/QTc Study of 2 Doses of ADASUVE® in Healthy Volunteers

Assess the potential effects on the QT interval of 2 consecutive doses of ADASUVE administered 2 hours apart, in relation to placebo and an active control in healthy volunteers.

It has been shown in a pre-marketing clinical study that clinically relevant QT prolongation does not appear to be associated with a single dose of ADASUVE. The potential risk of QTc prolongation following repeat dosing is unknown. Therefore the current study will assess the potential effects on the QT interval of 2 consecutive doses of ADASUVE administered 2 hours apart, in relation to placebo and an active control in healthy volunteers.

The study hypothesis H0: Placebo-subtracted max mean dQTc > 10 msec
