Clinical Trial Summary

This is a Phase II screening study of lithium carbonate in ALS. The purpose of this study is to find out if lithium carbonate is safe to be used in people with ALS and if it can slow the progression of the disease. Since there is no placebo in this study, all patients will be taking lithium carbonate.

Description:

This is a Phase II Screening study. There is no placebo (inactive or 'fake' drug) in this study, meaning that all participants will be taking lithium carbonate. The purpose of this study is to find out if lithium carbonate is safe to be used in people with ALS and if it can slow the progression of the disease.

A recent article was published in a highly regarded medical journal that showed a positive effect of lithium carbonate on an ALS type mouse. The researchers then studied a very small number of people with ALS, giving 16 people lithium carbonate with riluzole and giving 28 people only riluzole. The people who took lithium remained stronger for a considerably longer period of time. However, the study was very small and we cannot really tell if lithium works unless a larger study is performed. It is not well understood why lithium carbonate might be helpful but it is believed that it may play a role in protecting the motor nerves from the damage of ALS.

If you choose to participate, you will need to go to your study clinic for research study visits 7 times in one year and you will have 4 telephone interviews during that time. These visits and phone calls could take up to 17 hours in total.

Caution: Lithium is an FDA approved drug used for some psychiatric disorders. It is not FDA approved for ALS. Lithium has many potentially serious side effects and must only be taken under close supervision of your physician.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Monthly Rate of Decline in ALSFRS-R (Amyotrophic Lateral Sclerosis Functional Rating Score - Revised)	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)	Baseline, Month 1,3,4.5,6,7.5,9,10.5,12,13
Secondary	Vital Capacity	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.	Screen, Baseline, Month 1,3,6,9,12
