Monthly interim analyses will monitor the subjects using validated ALS scales such as the ALSFRS-R and Appel Scale, which incorporates muscle strength and dysfunction, activities of daily living and pulmonary function. The analyses will also include interim medical history and physical exam, EKG when indicated, safety labs (such as CBC, chemistry, liver function, T4 and TSH) as well as more technical research labs such as T Regulatory Cell, Th1 and Th17 counts, FoxP3 RNA expression, and Treg Suppression Assays. A PT/PTT will be performed only if the subject has an abnormal coagulation result at baseline or if the subject is on anti-coagulation therapy.
