Trial 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. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 6 weeks
  • All sexes
  • No healthy volunteers
  • Child

Who may be able to join

  • 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)

Who cannot join

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

About this study

Official title: A Multicenter, Open-Label Study of the Safety, Tolerability, and Pharmacodynamics of Intravenously Administered cPMP (Precursor Z) in Patients With Molybdenum Cofactor Deficiency Type A

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • cPMPDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Urine biomarkers SSC and sulfite

    Measured: Daily collection throughout study; analyzed at 3 months

Secondary outcomes (2)
  1. neurological examination

    Measured: collected daily; analyzed at 3 months

  2. Safety measures (vital signs, adverse events)

    Measured: collected daily; analyzed at 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing cPMP in people with Molybdenum Cofactor Deficiency Type A, run by Orphatech Pharmaceuticals, GmbH at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 1 Feb 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Urine biomarkers SSC and sulfite (time frame: Daily collection throughout study; analyzed at 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00957749, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2011; AzTrials last refreshed its copy on 7 Nov 2026.
