Treatment and study plan

placebo/dalfampridine-ER

Drug

Sequence A: placebo in Period 1 and dalfampridine-ER in Period 2. 10mg tablets, will be taken orally, twice daily approximately 12 hours apart

dalfampridine-ER/placebo

Drug

Sequence B: dalfampridine-ER in Period 1 and placebo in Period 2. 10mg tablets, will be taken orally, twice daily approximately 12 hours apart

Primary outcomes

  1. Safety and Tolerability of Dalfampridine-ER in Subjects With Chronic Deficits After Ischemic Stroke Assessed by Number of Treatment Emergent Adverse Events (TEAEs)

    Time frame: up to 36 days

    A TEAE is defined as any adverse event with date of onset (or worsening) on or after the start-date of double-blind treatment through 7 days after the last dose of double-blind treatment.

    The severity categories of mild, moderate or severe, are defined below:

    • Mild is defined as causing no limitation of usual activities
    • Moderate is defined as causing some limitation of usual activities
    • Severe is defined as causing inability to carry out usual activities

Other outcomes

  1. Walking Speed Measured by the Timed 25 Foot Walk Test (T25FW)

    Time frame: Screening visit, Days 1, 8, 15, 22, 29 and 36

  2. Motor and Sensory Function as Measured by the Fugl-Meyer Assessment (FMA)

    Time frame: Screening visit, Days 1, 8, 15, 22, 29, and 36

  3. Manual Dexterity as Measured by the Box and Block Test

    Time frame: Days 1, 8, 15, 22, 29, and 36

  4. Assistance Required to Perform Activities of Daily Living (ADL) by the Functional Independence Measure (FIM) Scale

    Time frame: Days 1, 8, 15, 22, 29, and 36

  5. Subject Global Impression (SGI) Scale

    Time frame: Days 8, 15, 22, 29 and 36

  6. Clinician Global Impression (CGI) Scale

    Time frame: Days 8, 15, 22, 29 and 36

  7. Hand Strength as Measured by the Grip Test and Pinch Tests

    Time frame: Days 1, 8, 15, 22, 29, and 36
