Arm | Intervention/treatment |
---|---|
Placebo Comparator: (PART A) AB: dalfampridine-ER 10mg then placebo
Each subject randomized to the AB arm will receive a single witnessed dose of (A) dalfampridine-ER 10 mg, and a single witnessed dose of (B) placebo, two days apart
|
Drug: dalfampridine-ER 10mg Other: Placebo |
Placebo Comparator: (PART A) BA: placebo then dalfampridine-ER 10mg
Each subject randomized to the BA arm will receive a single witnessed dose of (B) placebo, and a single witnessed dose of (A) dalfampridine-ER 10 mg, two days apart
|
Drug: dalfampridine-ER 10mg Other: Placebo |
Placebo Comparator: (PART B) AB: dalfampridine-ER 10mg then placebo
Each subject randomized to the AB arm will receive multiple doses of (A) dalfampridine-ER 10mg and multiple doses of (B) placebo
|
Drug: dalfampridine-ER 10mg Other: Placebo |
Placebo Comparator: (PART B) BA: Placebo then dalfampridine-ER 10mg
Each subject randomized to the BA arm will receive multiple doses of (B) placebo, and multiple doses of (A) dalfampridine-ER 10mg

- Safety and Tolerability of Dalfampridine-ER 10mg in Subjects With Cerebral Palsy (CP) [ Time Frame: up to 31 days ]
Safety and tolerability will be assessed primarily by monitoring Treatment Emergent Adverse Events (TEAEs)
TEAEs are defined as Adverse Events (AEs) with date of onset (or worsening) on or after the start-date of double-blind treatment and no more than 5 days after the last dose of double-blind treatment for Part A of the study and no more than 9 days for Part B of the study.
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
- Measure the Effects of Both Single and Multiple Doses of Dalfampridine-ER 10 mg on Sensorimotor Function [ Time Frame: up to 31 days ]
- Hand strength as measured by a composite Z-score derived from the grip test, and key, tip and palmar pinch tests
- Manual dexterity as measured by the Box and Block Test
- Walking speed as measured by the Timed 25 Foot Walk (T25FW)
- Gait as measured by gait analysis equipment (to be performed by sites that have the capability to perform it)
-
For Part B only, subjective impressions of treatment as measured by:
- Subject Global Impression (SGI)
- Clinician Global Impression (CGI)
