Brief Summary:
The purpose of the study is to collect long-term safety data from subjects with Amyotrophic Lateral Sclerosis (ALS) exposed to dexpramipexole.

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: Dexpramipexole Phase 3

Detailed Description:
Amyotrophic Lateral Sclerosis (ALS) is a rapidly progressive, degenerative disease of motor neurons in the brain and spinal cord that leads to muscle atrophy and spasticity in limb and bulbar muscles resulting in weakness and loss of ambulation, oropharyngeal dysfunction, weight loss, and ultimately respiratory failure. The purpose of this study is to collect long-term safety data from subjects with Amyotrophic Lateral Sclerosis (ALS) exposed to dexpramipexole.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 80 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subject has the ability to understand the purpose and risks of the study and provide signed and dated informed consent (or have the consent confirmed by a witness if unable to write) and authorization to use protected health information (PHI) in accordance with national and local subject privacy regulations.
  • Subject was enrolled in either CL211 (NCT00931944) or Study 223AS302 (NCTO1281189).
  • Subject has completed their last visit in Study CL211 (NCT00931944) or Study 223AS302 (NCTO1281189).
  • Subjects of childbearing potential must practice effective contraception during the study and be willing and able to continue contraception for 1 month (females) or 3 months (males) after their last dose of study treatment.

Exclusion Criteria:

  • Subject withdrew prematurely from Study CL211 (NCT00931944) or Study 223AS302 (NCTO1281189).
  • Subject permanently discontinued study treatment in Study CL211 (NCT00931944) or Study 223AS302 (NCTO1281189) for any reason other than enrollment into this study.
  • Subject from Study CL211 (NCT00931944) or Study 223AS302 (NCTO1281189) has a significant change in medical history (including laboratory tests or a clinically significant condition) that in the opinion of the Investigator would impair the subject's medical fitness for participation and preclude treatment.
  • Female subject who is pregnant or breastfeeding.
  • Subject is currently enrolled in any investigational drug study other than Study CL211 (NCT00931944) or Study 223AS302 (NCTO1281189).
  • Subject is taking pramipexole, other dopamine agonists, any other agent with dopaminergic activity, or any other disallowed concomitant medication.
  • Subject is unwilling or unable to comply with the requirements of the protocol including the presence of any condition (physical, mental, or social) that is likely to affect the subject's ability to comply with the protocol. At a minimum, subjects who are not able to travel to the study site must be willing to agree to remote blood draws for clinical laboratory evaluations and telephone visits to report Adverse Events, concomitant medications, and Amyotrophic Lateral Sclerosis Functional Rating Scale (revised) (ALSFRS-R) scores.
