Amyotrophic Lateral SclerosisPhase 2NCT00005674
Clinical Trial of Creatine in Amyotrophic Lateral Sclerosis [ALS]
A Phase 2 study testing Creatine in people with Amyotrophic Lateral Sclerosis, run by National Center for Research Resources (NCRR) at 1 site in United States.
Trial summary
The purpose of this study is to evaluate the safety and effectiveness of creatine treatment in amyotrophic lateral sclerosis (ALS). There is currently no known effective treatment for ALS. It is known that nerve cells die in the brains and spinal cords of patients with ALS but the cause of the cell death is unknown. Read more about this study

About this study
The purpose of this study is to evaluate the safety and effectiveness of creatine treatment in amyotrophic lateral sclerosis (ALS). There is currently no known effective treatment for ALS. It is known that nerve cells die in the brains and spinal cords of patients with ALS but the cause of the cell death is unknown. It has been shown that there is overactive nerve activity due to increased levels of a chemical called glutamate and that there is abnormal cellular metabolism along with increased production of substance called "free radicals." Improving cellular metabolism and readjusting the activity of glutamate in the brain may be beneficial to ALS patients.
Creatine is a naturally occurring compound, which improves energy metabolism in cells. Creatine has been given to patients with energy metabolism defects in their muscles, and to athletes. Creatine improves survival in a mouse model of ALS. Three human subjects with ALS have received creatine for up to six months without any side effects. Overall, creatine has been well tolerated and safe.
Read the detailed description
Half of the subjects in this study will be selected by chance to receive creatine treatment for 6 months and the other half to receive placebo. Neither the subject nor the investigator will know which drug the subject is receiving, although this information will be available in case of emergency. It is anticipated that all subjects will have the choice to receive creatine after the 6 months study in an open-label study for an additional 12 months. A total of 114 patients will participate at 15 centers. Approximately 8 subjects will be enrolled at the Washington University.
The effectiveness of creatine will be determined first by assessing any changes in strength in the arms and second by changes in grip strength, functional activities, electromyography changes or changes of the level of SOH 2'dG in the urine.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Creatine in people with Amyotrophic Lateral Sclerosis, run by National Center for Research Resources (NCRR) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2005; AzTrials last refreshed its copy on 8 Nov 2026.
