Study Type Interventional
Study Design Allocation: N/A;   Intervention Model: Single Group Assignment;   Masking: None (Open Label);   Primary Purpose: Treatment
Condition Amyotrophic Lateral Sclerosis
Intervention Drug: lithium carbonate
Enrollment 109
Recruitment Details Patients were enrolled between May 2008 and February 2009. Inclusion criteria were a diagnosis of probable or definite ALS (12), age 21-85 years, forced vital capacity (FVC) greater than or equal to 75% of predicted, and onset of weakness within 3 years. Patients taking riluzole were on a stable dose for at least 30 days.
Pre-assignment Details

This was an open label single-arm Phase II screening trail. All enrolled subjects (n=109) were treated. Their results were compared with placebo subjects from an historical database of ALS placebo patients from recent studies (n=249). Thus the number enrolled (n=109) does not equal the total number of subjects (n=358).

Enrolled subjects started lithium carbonate at 150 mg twice daily. If subjects did not tolerate a dose it was tapered by 150 mg increments to the maximum tolerated dosage.

1.Primary Outcome
Title Change in Monthly Rate of Decline in ALSFRS-R (Amyotrophic Lateral Sclerosis Functional Rating Score - Revised)
Hide Description This questionnaire has 12 questions about the patient's ability to complete certain daily activities. There are three questions each about the mouth area, arms, legs, and breathing. A normal score is 48 with each question scored at 0 (worst) to 4 (normal function). In research studies, the change in slope is measured in number of points changed per month. Maximum possible=48 (normal) Minimum=0 (severe dysfunction)

2.Secondary Outcome
Title Vital Capacity
Hide Description Vital Capacity (VC) is a breathing test in which the patient is asked to take a deep breath and then blow out all of the breath through a tube. The volume is measured in number of liters. It is converted to a percent predicted for the patient's age, height, and gender.
