Impact of the Presence of a Feeding Tube on Tiratricol Maintenance Dosing and Efficacy Outcomes in Patients with MCT8 Deficiency

Groeneweg Stefan , Edward Visser W.(on behalf of the Triac Trial I investigators)

Objective: The Triac Trial I was a multicentre, open-label, single-arm, Phase II study of tiratricol (triac) in the treatment of monocarboxylate transporter 8 (MCT8) deficiency. The study demonstrated the beneficial effect of tiratricol in alleviating peripheral thyrotoxicosis. A subset of patients entered the study whilst having a feeding tube. Here, we investigate the impact of the presence of a feeding tube on tiratricol dosing and reaching the serum total ...

Introduction: Mutations in the thyroid hormone (TH) transporter MCT8 result in MCT8 deficiency, which is characterized by severe intellectual and motor disability and high serum T3 concentrations inducing thyrotoxicity in peripheral tissues. At present, no effective treatment is available, although preclinical studies suggest that the T3 analog Triac is a promising candidate to i) normalize serum T3 levels and thus alleviate the thyrotoxicosis and ii) restore TH signaling in t...
