Introduction to Trientine Tetrahydrochloride
Trientine tetrahydrochloride, marketed as Cuvrior™, is a copper chelating agent developed by Orphalan Inc. for the treatment of Wilson’s disease, a rare inherited disorder of copper transport that primarily affects the liver and brain. Here, we will delve into the recent clinical trials, market analysis, and future projections for this drug.
Clinical Trials Overview
CHELATE Trial
The CHELATE trial is a pivotal Phase 3 study that compared trientine tetrahydrochloride with d-Penicillamine, the traditional first-line treatment for Wilson’s disease. This multicenter, randomized, open-label, active-controlled, non-inferiority study was conducted in 9 countries across 15 centers. The trial involved 53 adult patients with stable Wilson’s disease who were followed for a baseline period of 12 weeks before being randomized to either trientine tetrahydrochloride or d-Penicillamine.
Key Findings:
- Trientine tetrahydrochloride was found to be non-inferior to d-Penicillamine in maintaining serum non-ceruloplasmin copper (NCC) levels, the primary endpoint[2][4].
- More patients treated with trientine tetrahydrochloride achieved the composite endpoint of NCC and 24-hour urinary copper excretion (UCE) within therapeutic target ranges compared to those treated with d-Penicillamine (50% vs 24%)[2].
Pediatric Clinical Trials
The FDA has mandated a clinical trial to study the safety and efficacy of trientine tetrahydrochloride in the pediatric population. This trial will evaluate dosing changes using half-tablet administration to accommodate young children. The timeline for this study includes:
- Draft Protocol Submission: August 2022
- Final Protocol Submission: December 2022
- Trial Completion: December 2025
- Final Report Submission: June 2026[1].
Safety and Tolerability
Trientine tetrahydrochloride has demonstrated a favorable safety and tolerability profile. The CHELATE trial and other studies have shown that it is well tolerated, with fewer adverse effects compared to d-Penicillamine. This is crucial for patients with Wilson’s disease, as interrupting or stopping treatment can lead to severe consequences[2][4].
