First EU-Authorised Treatment for MCT8 Deficiency (Allan-Herndon-Dudley)

Emcitate (tiratricol) — dispersible tablets for peripheral thyrotoxicosis in MCT8 deficiency

Compassionate Access · United States, European Union · September 22, 2026

Condition: MCT8 Deficiency (Allan-Herndon-Dudley Syndrome)

Who this is for

This is for people living with MCT8 deficiency (Allan-Herndon-Dudley syndrome) — and the caregivers who help them — who need an honest by-country path to tiratricol. It explains the first EU-authorised treatment for peripheral thyrotoxicosis from birth (EC 12 Feb 2025), Germany commercial launch, T3 titration from the SmPC, the main Triac / ReTRIACt / real-world evidence, and the US Expanded Access door (NCT05911399) while FDA review continues toward a 28 Sep 2026 PDUFA date — without claiming US or Canadian approval, treating completed research as walk-in enrolment, or importing foreign packs. Authorized is not funded.

Access doors

FDA Expanded Access (Patient Affairs)
US Food and Drug Administration path for a licensed clinician to request an investigational medical product for a patient with a serious or immediately life-threatening condition when no comparable approved therapy is available. This is a request path, not a labelled indication. Authorized is not funded.

CTIS (EU Clinical Trials Information System)
European Union public portal for clinical trials submitted under the Clinical Trials Regulation. Search by medicine, condition, and member state. A CTIS record is not an EMA marketing authorisation and is not enrolment.
https://euclinicaltrials.eu/
ClinicalTrials.gov
US National Library of Medicine registry of clinical studies. Search by condition, drug, NCT number, and location. A listing is not enrolment, eligibility, or funding. Talk with the trial contact and a clinician before assuming a slot exists.
