What researchers measure

Primary outcomes

  1. Placebo-corrected change-from-baseline QTcF (ΔΔQTcF) following AKB-6548 administration.

    Time frame: multiple timepoint evaluations from pre-dose to 24 hours post-dose

Secondary outcomes

  1. Placebo-corrected change-from-baseline heart rate (HR), PR interval, QRS interval

    Time frame: multiple timepoint evaluations from pre-dose to 24 hours post-dose

  2. Categorical outliers defined as QTcF >450 msec, 480 msec and 500 msec at any timepoint and change-from-baseline QTcF (ΔQTcF) >30 msec (increased by 30 msec) and >60 msec

    Time frame: multiple timepoint evaluations from pre-dose to 24 hours post-dose

  3. Categorical outliers for HR, PR interval, QRS interval

    Time frame: multiple timepoint evaluations from pre-dose to 24 hours post-dose

  4. Frequency of T wave morphology changes

    Time frame: multiple timepoint evaluations from pre-dose to 24 hours post-dose

  5. Placebo-corrected change-from-baseline QTcF (ΔΔQTcF) following moxifloxacin administration

    Time frame: multiple timepoint evaluations from pre-dose to 24 hours post-dose

  6. Safety parameters to include adverse events; changes in routine clinical laboratory measures including chemistry, hematology, and urinalysis; and clinically significant changes noted during physical examinations or in vital signs

    Time frame: from first dose of study medication through the final protocol required visit
