Brief summary

A randomised, open-label study evaluating the pharmacokinetics, safety, and tolerability of a new once daily dose of 900mg of TETA 4HCL by comparing it against the current marketed Cuprior® formulation (450mg trientine base, twice daily) in healthy male and female participants.

Detailed description

This is a single centre, phase I, randomized, controlled trial with a crossover design to evaluate the pharmacokinetics (PK), safety, and tolerability of a new once daily TETA 4HCL formulation (300mg) (3x300mg trientine base tablets, OD) compared to the current marketed Cuprior® formulation (150mg) (3x150mg trientine base tablets, BD) in adult healthy male and female participants. Participants: 26 healthy participants will be enrolled to ensure 24 participants complete the study, with a balanced gender split. Treatment: Participants will be randomized to receive either the new or the current formulation of the drug, and then switch to the other formulation after a period of time (see study flow chart below). To remain in line with current EU SmPC and US PIL, being: * EU daily dose range of 450-975 mg of trientine base * US daily dose range of 150-1500mg trientine base the following treatments will be administered according to the treatment allocation schedule below: A: 900mg TETA 4HCl once a day / new formulation = 3 tablets of 300mg trientine base as a single dose B: 900mg TETA 4HCl marketed Cuprior formulation = 6 tablets of 150mg trientine base in two equally divided doses Patients will be randomised in a 1:1 ratio to either one of the following sequences: Treatment Sequence Period 1 Period 2 Sequence 1 Treatment A Treatment B Sequence 2 Treatment B Treatment A Assessments: Participants will be assessed for eligibility criteria and will be monitored closely throughout the study. Assessments will be performed during the study and at the end of the study follow-up visit. Duration: The duration of the study will be up to approximately 7 weeks, from screening to follow-up: * Screening will take place between days -28 and -2 * In-house period from D-1 to D3 with dosing on D1 of each treatment period * Follow-up will take place on D7 of Treatment Period 2 At least 5 days and a maximum of 10 days between treatment period study drug administration Objective: To evaluate the PK, safety, and tolerability of the new once daily TETA 4HCL formulation compared to the current marketed Cuprior® formulation.

To Compare the Safety and Tolerability of the Two TETA 4HCL Tablet Formulations.

The incidence, severity, and relationship of Treatment-Emergent Adverse Events (TEAEs).

Time frame: Adverse events were collected from the patient signing the ICF until the end of study/follow-up (EOS/FU) visit. The Mean (Min, Max) number of days between signing ICF and the EOS/FU visit in the study was 20.2 (16, 25). All patients completed the study.
