Brief Summary:

Molybdenum Cofactor Deficiency Type A (MoCD) is a very rare autosomal recessive disorder that is essentially fatal early in life. Naturally occurring cPMP is present in the body of all healthy normal individuals. It is processed to molybdopterin, which is further processed to molybdenum cofactor. Molybdenum cofactor is essential for the function of important enzymes.

There is currently no treatment for MoCD, and affected infants develop severe neurological damage which often results in infant death.

This study is the first clinical trial to investigate the potential of replacement of cPMP to infants with MoCD Type A. The safety, tolerability, and pharmacodynamics of daily intravenous administration of cPMP over 3 months will be determined.

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Neonate or infant, less then 6 weeks at the time of diagnosis, age less than 8 weeks at start of treatment with the study medication. It is important to diagnose the condition and initiate treatment as soon after birth as possible.
  • Documented diagnosis of molybdenum cofactor deficiency (MoCD) Type A based on the absence of cPMP and the presence of sulfite and s-sulfocysteine in the urine, absence of urothione in the urine and genetic analysis showing a mutation in the MOCS1 gene
  • A parent or legal guardian voluntarily provided written informed consent to participate in the study and comply with study procedures.
  • Approval of the study protocol by the local HE / IRB and government or regulatory authorities (if applicable)

Exclusion Criteria:

  • MoCD Type B (MOCS2 mutation) or Type C (gephyrin gene mutation)
  • Sulfite oxidase deficiency
  • Patients older than 6 weeks at the time of diagnosis
