Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Valproic acid (VPA) is a medicine that has been used for many years to treat patients with epilepsy. Recent research suggests that VPA may be able to upregulate expression of a backup copy of the SMN gene in SMA patient cell lines. In addition, some preliminary data suggests it may prolong survival in animal models of SMA. Because VPA can deplete carnitine in children with SMA Type I, carnitine is added to help prevent possible toxicity.
In this multi-center trial, we will evaluate the effects of VPA/carnitine on infants with SMA type I. A variety of outcome measures, including assessment of safety, will be performed at each study visit to follow the course of the disease. The protocol includes two baseline visits over a period of two weeks, two clinical assessments on medication at 3 and 6 months, and then 6 months additional followup via telephone. Total duration of the study will be approximately 12 months.

Exclusion Criteria

Liver transaminases (AST, ALT), lipase, amylase: \> 1.5 x ULN White Blood Cell Count: \< 3 Neutropenia: \<1 Platelet: \<100K Hematocrit: \<30, persisting over a 30-day period
* Serious illness requiring systemic treatment and/or hospitalization within two weeks prior to study entry.
* Use of medications or supplements within 30 days of study enrollment that interfere with VPA or carnitine metabolism; that increase the potential risks of VPA or carnitine; or that are hypothesized to have a beneficial effect in SMA animal models or human neuromuscular disorders, including riluzole, valproic acid, hydroxyurea, oral use of albuterol, sodium phenylbutyrate, butyrate derivatives, creatinine, growth hormone, anabolic steroids, probenecid, oral or parenteral use of corticosteroids at entry, or agents anticipated to increase or decrease muscle strength or agents with presumed histone deacetylase (HDAC) inhibition.
* Infants who have participated in a treatment trial for SMA within 30 days of study entry or who will become enrollees in any other treatment trial during the course of this study.
* Unwillingness to travel for study assessments.
* Coexisting medical conditions that contradict use of VPA/carnitine or travel to and from study site.
