55 YearsInclusion Criteria:
- Must give written informed consent.
- Adult males/females aged 18 to 55 years inclusive and between 19 and 30 kg/m2 body mass index (BMI), inclusive at screening.
- Subjects who are healthy as determined by prestudy medical history, physical examination and 12-lead ECG.
- Subjects of childbearing potential must practice effective contraception during the study and be willing and able to continue contraception for 1 month (females) or 3 months (males) after their last dose of study treatment.
- 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.
- History of cardiovascular disease (e.g., hypertension, arrhythmia, heart failure, Long QT Syndrome, or other conditions/diseases causing prolongation of the QT/QTc interval).
- A prolongation of QT/QTc interval (e.g., repeated demonstration of a QT/QTc interval >450 ms before study treatment administration) at screening, admission or pre-dose on Day 1.
- Any clinically important abnormalities in resting ECG that may interfere with the interpretation of QTc interval changes at screening, admission or pre-dose on Day 1.
- Prior exposure to dexpramipexole.
- Treatment with pramipexole or any dopamine agonist within 1 year.
- Treatment with another investigational drug or approved therapy for investigational use within 30 days, or 5 half-lives (whichever is longer), or in follow up for any other drug, biologic, or device study.
- Currently active infection or serious infection (e.g., pneumonia, septicemia) within the 2 months prior to Day -2 as determined by the Investigator.
- Female subjects who are pregnant, currently breastfeeding, or attempting to conceive during the study.
