Brief Summary:
To evaluate whether dexpramipexole prolongs the QTc interval when orally administered to healthy volunteers.

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: Dexpramipexole Drug: Dexpramipexole Placebo Drug: Moxifloxacin Phase 1

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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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 ]

Secondary Outcome Measures :
  1. 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 ]
  2. Change in ECG measurements [ Time Frame: baseline and Day 7 ]
  3. 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 ]
  4. 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 ]

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
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.
