About this study

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

    Time frame: Predose, 2 min, 1, 1.5 hr, 2 hr 2 min, 2 hr 5 min, 2.5, 3, 5, 8, 12, and 24 hr

    Time-matched differences in QTcI values between the maximum of the mean difference from baseline of the QTcI interval after time-matched placebo subtraction for ADASUVE treatment at 12 post-inhalation times.

Secondary outcomes

  1. QTc Versus Loxapine Concentration

    Time frame: Predose, 2 min, 1, 1.5 hr, 2 hr 2 min, 2 hr 5 min, 2.5, 3, 5, 8, 12, and 24 hr

  2. Subjects With QTcI > 450 ms

    Time frame: Predose, 2 min, 1, 1.5 hr, 2 hr 2 min, 2 hr 5 min, 2.5, 3, 5, 8, 12, and 24 hr

    Numbers of Subjects with QTcI > 450 ms at any time point

  3. Subjects With QTcI > 480 ms

    Time frame: Predose, 2 min, 1, 1.5 hr, 2 hr 2 min, 2 hr 5 min, 2.5, 3, 5, 8, 12, and 24 hr

    Numbers of Subjects with QTcI > 480 ms (or 500 ms) at any time point

  4. Subjects With QTcI Increase > 30 ms From Baseline

    Time frame: Predose, 2 min, 1, 1.5 hr, 2 hr 2 min, 2 hr 5 min, 2.5, 3, 5, 8, 12, and 24 hr

    Numbers of Subjects with QTcI Increase > 30 ms from Baseline at any time point

Other outcomes

  1. Maximum Effect of Moxifloxacin on Cardiac Repolarization (QTc Interval Duration) Compared to Placebo (Study Assay Sensitivity)
