About
Tralement versus a fixed-dose trace element combination product of zinc, copper, and selenious acid to evaluate product safety in pediatric patients >3 to 17 years of age requiring long-term parenteral nutrition.
Full 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 pediatric 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 either 2 (3.5-<7 years of age) and 4 (7-16 years of age) 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.

Inclusion criteria
- Pediatric (≥3 to 17 years of age) participants weighing >10 kg with assent to participation and his/her parent or legal guardian is willing and able to sign the informed consent approved by the Institutional Review Board (IRB) or Independent Ethics Committee (IEC).
- Male and female participants who are new users to home parenteral nutrition as a source of trace elements when oral or enteral nutrition is not possible, insufficient, or, contraindicated.
- Anticipated duration of home parenteral nutrition use is 6 months or greater.
- A normal baseline brain MRI scan.
- A normal blood manganese concentration.
- Ability to undergo additional 2 brain MRI scans over the six-month study period (Sedation, if appropriate, to be determined by the Principal Investigator's study site, institutional review board recommendations, and parent/guardian assent).
- Definitive contraception for females of reproductive age.
Exclusion criteria

- Baseline Transferrin Saturation (TSAT) ≥45% or below 20%.
- Prior or current cholestatic liver disease defined as a clinical condition associated with decrease in bile flow due to impaired secretion by hepatocytes or to obstruction of bile flow through intra-or extrahepatic bile ducts.
- Liver function studies with transaminases greater than two-fold normal or total bilirubin >2 mg/dL.
- Brain MRI exclusion criteria: MRI-unsafe metal implants, claustrophobia.
