Filter by:Urea cycle disorders are rare inherited diseases that generally have a poor outcome. In this study, neonates and infants with UCD will be included within the first 3 months of life and will be treated by repetitive application of human liver cells to reduce the risk of neurological deterioration while awaiting OLT.
The purpose of this study is to determine whether HPN-100 is safe and tolerable in subjects with Urea Cycle Disorders.
Urea cycle disorders are inherited illnesses in which the body does not produce enough of the chemicals that remove ammonia, a byproduct of protein metabolism, from the blood stream. Elevated ammonia levels can lead to brain damage and death. Argininosuccinic aciduria (ASA) is a type of urea cycle disorder that is characterized specifically by high levels of argininosuccinic acid, a chemical involved in the urea cycle. People with ASA are at risk for serious liver damage, which may be due to the elevated levels of argininosuccinic acid. Sodium phenylbutyrate (Buphenyl-TM) is a drug that has been used to treat other types of urea cycle disorders. This study will evaluate whether Buphenyl-TM in conjunction with decreased arginine dose (in addition to a normal regimen of protein) will improve short-term liver function and decrease plasma citrulline and ASA levels in people with ASA.
Urea cycle disorders (UCD) are a group of rare inherited metabolism disorders. Infants and children with UCD commonly experience episodes of vomiting, lethargy, and coma. The purpose of this study is to perform a long-term analysis of a large group of individuals with various UCDs. The study will focus on the natural history, disease progression, treatment, and outcome of individuals with UCD.
