Summary
The objectives of this trial are: to establish a safety profile for use of Hydroxyurea in children with Type I Spinal Muscular Atrophy; to identify reliable outcome measures for HU treatment in Type I SMA; and to detect the clinical efficacy of HU treatment in children with Type I SMA.
Eligibility Criteria
Inclusion Criteria:1. Laboratory confirmation of a homozygous deletion or mutation of the SMN1 gene 2. Clinical Diagnosis of Type I SMA (never achieved independent sitting) 3. Onset of disease before the age of 6 months 4. Enrollment in study within 6 months of diagnosis Exclusion Criteria:1. Known hematological disorders, such as chronic anemia (defined as platelet count less than 100,000/mm^3) in two contiguous measures in two weeks 2. Severe systemic disorders such as congenital heart disease, other major birth defects involving internal organs, or severe birth asphyxia 3. Participation in SMA clinical trials for other experimental drugs 4. Requiring continuous respiratory support before the initiation of HU treatment
