Condition(s) targeted: Healthy Volunteers

Intervention: ADASUVE 10 mg 2 doses 2 hours apart (Drug); Oral moxifloxacin 400 mg (Drug); Staccato Placebo 2 doses 2 hours apart (Drug); Placebo (for moxifloxacin) (Drug)

Phase: Phase 1

Status: Completed

Teresa Nunes, MD, Principal Investigator, Affiliation: PRA Health Sciences


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
