Brief Summary:
This randomized, double-blind, controlled, outpatient two-period, two-treatment crossover study is designed to evaluate the efficacy and safety of amifampridine phosphate in patients (ages 2 and above) diagnosed with certain genetic subtypes of CMS and demonstrated open label (amifampridine phosphate) or history of sustained amifampridine benefit from treatment.
Detailed Description:
Each patient will participate in an open-label unblinded drug escalation/treatment run-in phase for up to 4 weeks until stable dose and frequency of amifampridine phosphate is achieved for 7 days. After this phase, blinded treatment effect will be assessed in a randomized fashion of continuation or cessation of drug (Placebo) starting with Period I (duration 7 days). Following experimental Period 1, patients will be returned to the stable dose administered at the end of the open-label run-in period for approximately 2 weeks, followed by cross over treatment in Period 2 dosing for 7 days. After completion of Period 2, patients will be eligible for expanded access with restoration of open-label amifampridine phosphate at the same dose and frequency as established in the run in phase of the study.
