About this study
Official title: A Randomized, Single-blind, Trial of Tralement Versus a Fixed-dose Trace Element Combination Product of Zinc, Copper, and Selenious Acid to Evaluate Manganese Safety in Adult Patients Requiring Long-term Parenteral Nutrition
Tralement versus a fixed-dose trace element combination product of zinc, copper, and selenious acid to evaluate product safety in adult patients requiring long-term parenteral nutrition.
Read the detailed description
A Phase IV, multi-center, randomized single-blind trial to evaluate the safety profile of Tralement versus a fixed-dose trace element product of zinc, copper, and selenious acid in adult patients who are expected to require at least six-months of home parenteral nutrition.
This study will enroll new prescribed home parenteral nutrition users, i.e. a patient enrolled in the study within six weeks of initiating first-time use of parenteral nutrition requiring trace element additives. Note: a portion of patients who meet inclusion criteria may have received parenteral nutrition in an inpatient setting before discharge home.
Eligible participants who satisfy the inclusion requirements and no exclusion criteria will be consented to participate in this study and enter the screening study phase.
The screening evaluation will be conducted within 5 days of the dose administration of study drug. Study participants meeting entry criteria of normal brain MRI and laboratory manganese concentrations (whole blood/plasma/serum/RBC) will begin study drug on Day 1.
Participants will undergo 2 additional post-baseline brain MRI scans at Months 3 and 6 and have 5 separate neuropsychological tests at Day 1, Month 3, and Month 6. Additional clinical monitoring including safety and laboratory assessments will occur during the 6-month opt-in extension study.
All patients in each assigned trace element parenteral nutrition group will have parenteral nutrition formulations evaluated for manganese content at Day 1, Month 1, Month 3, and Month 6.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Tralement and Fixed-dose trace element combination product of zinc, copper, and selenious acid in people with Manganese Safety in Adults, run by American Regent, Inc..
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 7 inclusion and 12 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 12 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
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 phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
To assess brain deposition of manganese in Tralement versus a fixed-dose trace element product of zinc, copper, and selenious acid. (time frame: 6 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 12 Feb 2025.
