A Longitudinal Study of Amyotrophic Lateral Sclerosis (ALS) Biomarkers

A Multicenter Study for the Discovery and Validation of ALS Biomarkers

The purpose of this study is to collect biofluid samples for the banking and usage in ALS research. Through comparison of these samples, the researchers hope to learn more about the underlying cause of ALS, as well as find unique biological markers, which could be used to develop new therapies.

The purpose of the research study is to collect blood samples and cerebrospinal fluid (CSF) from people with amyotrophic lateral sclerosis (ALS). These samples will be collected approximately every 4 months.

Inclusion Criteria:

• Age 18 or older
• Diagnosis of suspected, possible, probable or definite ALS according to El Escorial Criteria
• Vital capacity (VC) at least 50 percent predicted
• Able to undergo multiple lumbar punctures

Exclusion Criteria:

• Abnormal CSF pressure or intracranial/intraspinal tumors

• Use of anticoagulant medication that cannot be safely withheld

• Bleeding disorders
