* Negative urine pregnancy test for females of childbearing potential at Screening.
* If sexually active and of childbearing potential, willing to use 2 acceptable methods of contraception from screening visit until 3 months after the last dose of investigational product. No adequate clinical data on exposed pregnancies are available for amifampridine. No nonclinical safety data are available regarding the effects of amifampridine on reproductive function. Amifampridine phosphate should not be used during pregnancy. It is unknown whether amifampridine is excreted in human breast milk. The excretion of amifampridine in milk has not been studied in animals. Amifampridine phosphate should not be used during breastfeeding.
* Any subject currently participating in study CMS 001 is immediately eligible for enrollment into study EAP-001, as long as inclusion/exclusion criteria are still met.
* Willing and able to provide written informed consent after the nature of the study has been explained and before the start of any research-related procedures.

* Known active brain metastasis. Patients with treated brain metastasis (radiotherapy and/or surgery) who have completed treatment for their brain metastasis \>90 days before Screening, are neurologically stable (neurological symptoms grade \<1), are on a stable dose of corticosteroids and have no evidence of new disease on magnetic resonance imaging (MRI) are eligible, provided they meet the other inclusion/exclusion criteria.
* Current use of dalfampridine (Ampyra®; 4-aminopyridine), and any form of 3,4 DAP other than the investigational product provided, such as amifampridine base and does not agree to discontinue use for the duration of the study.
* Use of guanidine hydrochloride within 7 days of starting amifampridine phosphate treatment.
* History of drug allergy to any pyridine-containing substances or any amifampridine phosphate excipients (i.e. microcrystalline cellulose, colloidal silicon dioxide or calcium stearate).
* Use of any other investigational product (other than 3,4 DAP or amifampridine phosphate) or investigational medical device within 30 days before starting treatment or requirement for any investigational agent before completion of all scheduled study assessments.
* An electrocardiogram (ECG) within 6 months before starting treatment that shows clinically significant abnormality(ies), in the opinion of the patient's personal physician for pediatric subjects \<18 years of age.
