Primary Outcome Measures:
  • To evaluate whether a single dose of dexpramipexole prolongs the QTC interval as measured by frequent ECG measurements (using Holter monitoring) of individually corrected QT intervals (QTcI) [ Time Frame: change from baseline ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Area Under Curve (AUC) of dexpramipexole [ Time Frame: pre-dose and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, and 23 hours after dosing on Day 1 of each treatment period ] [ Designated as safety issue: Yes ]
  • Change in ECG measurements [ Time Frame: baseline and Day 7 ] [ Designated as safety issue: Yes ]
  • Cmax of dexpramipexole [ Time Frame: pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, and 23 hours after dosing on Day 1 of each treatment period ] [ Designated as safety issue: Yes ]
  • Tmax of dexpramipexole [ Time Frame: pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, and 23 hours after dosing on Day 1 of each treatment period ] [ Designated as safety issue: Yes ]

Detailed Description:

This is a Phase I, single-center, blinded (with respect to dexpramipexole administration), randomized, placebo- and active-controlled, 4-period crossover study in approximately 68 healthy volunteers. This thorough QT/QTc study will be conducted to formally evaluate the effect of dexpramipexole on QT prolongation.

  Eligibility

Ages Eligible for Study:   18 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Aged 18 to 60 years old inclusive on Day 1.
  • Subjects who, in the opinion of the Investigator, are healthy as determined by pre study medical history, physical examination, and 12 lead ECG.
  • Male subjects and female subjects of childbearing potential must practice effective contraception (per protocol specifications).
  • Normal systemic blood pressure defined as a systolic blood pressure of 90 to 140 mmHg and a diastolic blood pressure of 50 to 90 mmHg.

Exclusion Criteria:

  • History of cardiovascular disease (e.g., hypertension, arrhythmia, heart failure, Long QT Syndrome, or other conditions/diseases causing prolongation of the QT/QTc interval), in the opinion of the Investigator.
  • A prolongation of QT/QTc interval (e.g., repeated demonstration of a QT/QTc interval >450 ms before study treatment administration.
  • Clinically important abnormalities in resting ECG that may interfere with the interpretation of QTc interval changes at screening, check-in, or pre-dose on Day -1 of the first treatment period.
  • Other medically significant illness.
  • Clinically significant abnormal laboratory values.
  • Pregnant women or women breastfeeding.
