Study Endpoints

Primary Endpoints

Maximum Serum Concentration in Pre Dose Corrected Data (Cmax[aj]) of Levothyroxine (T4)
Pre-dose, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.25, 3.5, 3.75, 4.0, 4.25, 4.5, 4.75, 5.0, 5.5, 6.0, 6.5, 8.0, 10.0, 12.0, 24.0, 36.0 and 48.0 hours post-dose

Cmax was obtained from the concentration time curve. Cmax\[aj\] was the maximum serum concentration in pre dose corrected data where pre dose corrected data was obtained by subtracting pre dose level of Levothyroxine (T4) from level of Levothyroxine (T4) after administration.

Area Under Serum Concentration-Time Curve From Time Zero to The Last Sampling Time in Pre Dose Corrected Data (AUC0-t [aj]) of Levothyroxine (T4)
Pre-dose, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.25, 3.5, 3.75, 4.0, 4.25, 4.5, 4.75, 5.0, 5.5, 6.0, 6.5, 8.0, 10.0, 12.0, 24.0, 36.0 and 48.0 hours post-dose

AUC0-t was defined as area under the curve of the serum concentration as a function of time, from time 0 until the last sampling time by means of the trapezoidal rule. AUC0-t \[aj\] was the area under the serum concentration-time curve from time zero to the last sampling time in pre dose corrected data where pre dose corrected data was obtained by subtracting pre dose level of Levothyroxine (T4) from level of Levothyroxine (T4) after administration.

Secondary Endpoints

Time to Reach Maximum Serum Concentration (Tmax) of Levothyroxine (T4)

Elimination Half-Life (t1/2) of Levothyroxine (T4)
Pre-dose, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.25, 3.5, 3.75, 4.0, 4.25, 4.5, 4.75, 5.0, 5.5, 6.0, 6.5, 8.0, 10.0, 12.0, 24.0, 36.0 and 48.0 hours post-dose
Area Under The Curve of the Serum Concentration as a Function of Time, From Time Zero to The Last Sampling Time (AUC0-t) of Levothyroxine (T4)
Pre-dose, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.25, 3.5, 3.75, 4.0, 4.25, 4.5, 4.75, 5.0, 5.5, 6.0, 6.5, 8.0, 10.0, 12.0, 24.0, 36.0 and 48.0 hours post-dose

Frequently asked questions about Reference Eutirox

What is Eutirox?

Eutirox is a small molecule therapeutic developed by Merck KGaA. It is in Phase 1 clinical development. The specific indications for Eutirox are undisclosed, and it is classified within a therapeutic area outside the main categories. Eutirox is also known as Reference Eutirox and Eutirox.

Who makes Eutirox?

Eutirox is developed by Merck KGaA, which trades under the ticker MKGAF. Merck KGaA is the company responsible for the clinical development of Eutirox, including the Phase 1 study conducted in Mexico.

What phase is Eutirox in?

Eutirox is in Phase 1 clinical development. It has completed one Phase 1 trial and has no active trials at this time. Eutirox is investigational and has not been approved by the FDA for any indication.

What clinical trials is Eutirox in?

Eutirox has been studied in one completed Phase 1 trial, NCT03979274, titled A Comparative Study of New Formulation and Approved Formulation for Levothyroxine in Healthy Volunteers. The trial enrolled 44 healthy volunteers in Mexico, was randomized and controlled, and included both male and female participants aged 18 years and older.

Is Eutirox the same as Reference Eutirox?

Yes, Eutirox is also known as Reference Eutirox, Reference Eutirox, and Eutirox. These names refer to the same investigational small molecule therapeutic developed by Merck KGaA. Searches for any of these alternative names will lead to the same drug asset.
