A randomized placebo controlled double-blind cross-over trial of Dalfampridine ER for effect on ambulatory activity in people with multiple sclerosis

Study summary:

This is a parallel-group, double-blind, randomized controlled crossover trial with a 1:1 randomization. There are two treatment periods of 4 weeks and a two-week off treatment washout period. Treatment periods are DER (dalfampridine ER) followed by placebo (group A) and placebo followed by DER (group B), respectively. All dosages will be administered twice a week. Purpose of the study is to see if using the study drug(dalfampridine Er) for a short period of time will improve the way subjects with multiple sclerosis (MS) walk.

Exclusion Criteria: - use of 4-aminopyridine within 6 months of screening - Any contraindication to DER: - Allergy to DER - history of seizure disorder or history of EEG showing epileptiform activity - Renal insufficiency (estimated GFR < 60. - Any condition that would exclude 6 minute walking testing: - Cardiac surgery or myocardial infarction within the last 3 months. - Severe aortic stenosis or hypertropic cardiomyopathy. - Pulmonary embolus or infarction in the last 6 months. - Uncontrolled hypertension by history or by screening or baseline diastolic blood pressure > 170, or systolic blood pressure > 105. - Use of oxygen at home for 24 hours/day or severe lung disease. - History of ventricular arrhythmia or finding of significant ventricular arrhythmia. atrial arrhythmia or 2nd or 3rd degree heart block on screening ECG. - Concomitant neurological disease, such as ALS, Parkinson Disease, stroke. - Hospitalization in the last 6 months for psychiatric illness. - Alcohol or drug abuse within the past year. - Females who are breast-feeding, pregnant or have potential to become pregnant during the course of the study( fertile and unwilling/unable to use effective contraceptive measures) - Cognitive deficits that would interfere with the subject's ability to give informed consent or preform study testing. - Any other serious and/or unstable medical condition. - Use of mitoxantrone (Novantrone) within 6 months of baseline visit.
