• Age range between 21 to 85 years, inclusive, at the Screening Visit
• Subjects who have experienced an ischemic stroke documented by CT or MRI resulting in an upper extremity deficit that, in the opinion of the Investigator, warrants the need for rehabilitation therapy
• Medically stable subjects who are able to be randomized to study medication beginning between ≥ 2 and ≤ 52 weeks post-stroke
• Subjects who have initiated, are undergoing, have completed or agree to begin physical or occupational rehabilitation for at least 2 weeks prior to study Day 1.

• Subjects with unresolved upper or lower motor deficits (e.g., range of motion or strength deficits) from any prior stroke
• Significant hemorrhagic stroke
• Any history of seizure disorder or a spontaneous seizure that had occurred at any time after the stroke
